CROSS REFERENCE TO RELATED APPLICATIONS

This application is a National Phase application of International Application No. PCT/JP2005/013562, filed Jul. 25, 2005, which claimed priority to Japanese Application No. 2004-216937, filed Jul. 26, 2004, each of which is hereby incorporated by reference herein in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to saddle type vehicles and, more particularly, to a speed change controller for saddle-type vehicle.

2. Description of the Related Art

Conventionally, it is usual in vehicles that a driver's speed change device is mechanically and directly transmitted to a transmission by the use of a link, a rod, or wire to perform speed change operation. In recent years, however, there is proposed to adopt a shift actuator making use of an electric motor or the like to perform speed change operation for the purpose of making speed change operation by a driver easier. For example, JP-A-2001-050389 is as an example of such a shift actuator.

However, the above-referenced publication includes only a description to the effect that instructions of speed change for electrically-driven speed change control may be input into a control unit by a foot-moving type speed change pedal, and does not describe any concrete means for execution of such instructions of speed change. Accordingly, there remains a need for a speed change controller suited to manipulation by a foot.

DETAILED DESCRIPTION

OF THE PREFERRED EMBODIMENTS

“Motorcycle” referred to in the specification of the present application means a motorcycle, includes a bicycle with a motor (motorbike), scooter, and specifically means a vehicle capable of turning with a vehicle body inclined. Accordingly, “motorcycle” includes three-wheeler, four-wheeler (or more), in which at least one of a front wheel and a rear wheel comprises two or more wheels and which is three and four in number of tires. Also, “motorcycle” is not limited to motorcycles but applicable to other vehicles, which can make use of the effect of the invention. “Motorcycle” is applicable to, for example, a so-called saddle-ride type vehicle including four-wheel buggy (ATV (all-terrain vehicle)) and snowmobile.

“Saddle-type vehicle” widely includes vehicles assuming the same ride configuration as or similar to that of a motorcycle.

Also, “operation part” of a saddle-type vehicle disclosed herein can include a part (for example, a shift pedal in a motorcycle) directly manipulated by a foot, and a part (that is, a part indirectly manipulated on the basis of manipulation of a foot) linking with the former part to operate interlocking with the motion of the former part. Accordingly, the part directly manipulated by a foot included in the operation part and the part indirectly manipulated on the basis of manipulation of a foot, both the parts being included in the manipulating part, can be arranged in different regions of a vehicle while interlocking mutually by a link member.

While preferred embodiments of a speed change controller (typically, a device being electrically driven to exercise speed change control) for saddle-type vehicles will be described below with reference to the drawings, it is not intended that the invention is limited to such illustrated examples.

First, a first embodiment of a speed change controller disclosed herein will be described with reference to FIGS. 1 to 5. FIG. 1 is a side view showing an outward appearance of a motorcycle 1 being a typical example of a saddle-ride type vehicle.

As shown in FIG. 1, the motorcycle 1 according to the embodiment is a sport type motorcycle 1 provided with a large-sized cowling 2, and generally comprises a front wheel 3, a rear wheel 4, a handle 5, a fuel tank 6, and a seat 7. An engine 12 can be supported by a vehicle body frame 10 and can be arranged below the fuel tank 6 and the seat 7. In the illustrated embodiment, a unit 100 (referred below to as “operation unit 100”), which comprises a detection mechanism of a speed change controller according to the illustrated embodiment, is arranged in a state of being supported on the vehicle body frame on a left side (specifically, a neighborhood of a left foot, which performs speed change operation) as viewed from a driver (referred below to as “rider”) in a riding state. Details of the operation unit 100 will be described below.

A general transmission (not shown) can be arranged in an engine casing 14 of the engine 12. The transmission can be a general, so-called dog clutch type transmission and can have, for example, four to six number of speeds. Motive power from a crankshaft of the engine 12 can be transmitted to a main axle and then transmitted to drive axles via gears and dogs of the respective number of speeds.

Speed change of the transmission can be performed by a speed change mechanism 20 of the speed change controller according to the illustrated embodiment. That is, as shown in the illustrated embodiment of FIG. 2, the speed change mechanism 20 comprises a shift fork 22 provided slidably on a slide rod 21 to regularly move slide gears of the transmission. Also, a shift cam 24 cant be provided rotatably to slide the shift fork 22.

A cam groove 24A can be formed on a periphery of the shift cam 24. The cam groove 24A can be formed to be shaped as shown in FIG. 3 and the shift fork 22 slides along the cam groove 24A.

Also, the shift cam 24 can be rotated via a ratchet mechanism 27 upon rotation of a shift shaft 23. The ratchet mechanism 27 can rotate the shift fork 22 by a uniform interval (angle) to regularly move the shift fork 22 and can have a ratchet function in both forward and backward directions to effect speed change one stage by one stage. A shift arm 25 of the ratchet mechanism 27 transmits rotation of the shift shaft 23 to the shift cam 24 and simultaneously restricts a stroke of the shift shaft 23 to prevent overrun of the shift cam 24. Also, a stopper plate 26 of the ratchet mechanism 27 can serve to fix the shift cam 24 to a predetermined position.

The shift shaft 23 can be turned in a predetermined direction by a driving force of a shift actuator 23B, a signal from the operation unit (detection mechanism) 100 described later can be inputted into an engine control unit (ECU) (depiction of which is omitted), and a signal from the engine control unit can drivingly control the shift actuator 23B. In addition, a detailed construction of the speed change mechanism may be the same as that of a conventional motorcycle.

Subsequently, the operation unit (detection mechanism) 100 according to the illustrated embodiment will be described in detail with reference to FIGS. 4 and 5.

In the illustrated embodiment, the operation unit 100 comprises a base plate 102 corresponding to “base” detachably mounted to the vehicle body frame 10 (or the engine casing 14 in another embodiment). The base plate 102 can be a substantially rectangular-shaped plate and can be mounted through mount holes 105A to 105D in four locations in total by screws (not shown) as shown in FIG. 4. The mount holes 66a can be a little larger in diameter than the thread diameter. Thereby, positional adjustment relative to an engine casing 14 is made possible.

Mounted to the base plate 102 can be an operation part 101, which can be operated by a foot for speed change. Also, formed on the base plate 102 can be a foot rest mount 103, to which a foot rest 9 affording placing a rider\'s left foot thereon is pivotally mounted.

The operation part 101 can comprise a shift pedal 110 corresponding to a moving part in the embodiment. The shift pedal 110 can comprise an arm portion 112, of which one end 112A can be mounted pivotally to an inner surface side (e.g., a side facing a vehicle body). The same can be applied in the base plate 102 and a pedal portion 114 being that portion, which is mounted to the other end 112B of the arm portion 112 can bee manipulated directly by a foot (a tip toe). Specifically, as shown in the illustrated embodiment of FIGS. 4 and 5, the end 112A of the arm portion 112 of the shift pedal 110 is mounted to a boss 104 of the base plate 102 in the vicinity of the foot rest 9 (that is, the foot rest mount 103) by a screw member 108 to freely turn (e.g., being able to swing in two vertical directions) about the screw member 108. Also, a pedal portion (pushed portion) 114 applied by a load from a foot can be provided substantially horizontally on the tip end 112B of the shift pedal 110 (the arm portion 112).

A detection unit 120 according to the illustrated embodiment can be provided on an outer surface side of the base plate 102. That is, the base plate 102 can comprise a sensor, for example, a potentiometer (e.g., a rotation sensor or an angle sensor, which is composed of a potentiometer having a variable resistance element) 122, which comprises a detection unit that detects that the shift pedal (moving part) 110 is moved a predetermined amount or more by manipulation of a foot. A sensor body 123 of the sensor 122 is fixed to the base plate 102. A turning plate 124 can be mounted to the sensor body 123 and can be configured to turn. The turning plate 124 can be turned whereby movement (turning) of the moving part in a predetermined direction can be detected. A detection signal can be transmitted to the engine control unit (ECU).

The turning plate 124 can be formed with a latch notch 125 as shown in FIGS. 4 and 5. Inserted into the latch notch 125 can be a latch pin 116, which can be protrusively provided on the shift pedal 110. With such construction, when the shift pedal 110 is turned, the turning plate 124 can be turned via the latch pin 116.

Also, in the illustrated embodiment, on an inner surface side of the base plate 102 can be provided spring, which can be in the form of a pine-needle shaped spring (e.g., as shown in the figure, a spring made of a metallic rod, of which a central portion is wound several turns and an angle between both straight ends of which is an acute angle) 131, which acts as “return mechanism” to return the shift pedal 110 to a predetermined neutral position.

The pine-needle shaped spring 131 can comprise a pair of rods (straight ends) 131A, 131B to generate spring elasticity. Interposed between the pair of rods 131A, 131B can be a part (referred below to as “push portion 112D”) of the arm portion 112 of the shift pedal 110 and a latch piece 109A of a retainer 109. As shown in FIG. 5, the retainer 109 can be fixed to the boss 104 of the base plate 102.

In addition, the push portion 112D can be formed on a bent part of the arm portion 112 of the shift pedal to be the same in width as other portions as shown in FIG. 5.

As described above, according to the illustrated embodiment, the moving part (shift pedal), the detection unit, and the return mechanism of the operation part are mounted to the base plate 102 to form an integral or single operation unit, so that the operation unit can be mounted integrally or as a group and detachably to the vehicle body frame 10 (or the engine casing 14). Therefore, the operation unit can contribute to an improvement in productivity of motorcycles.

Also, in the illustrated embodiment, two stopper pins 106, 107 can be mounted to the base plate 102. More specifically, as shown in FIGS. 4 and 5, the ascent stopper pin 106 can be mounted in a position, in which it abuts against an upper edge of the shift pedal 110 to be able to stop turning thereof when the shift pedal 110 is moved (turned) a predetermined amount upward as indicated by a two-dot chain line in FIG. 4. On the other hand, as shown in FIG. 4, the descent stopper pin 107 can be mounted in a position, in which it abuts against a lower edge of the shift pedal 110 to be able to stop turning thereof when the shift pedal 110 is moved (turned) a predetermined amount downward as indicated by a dashed line in FIG. 4.

In the illustrated embodiment, also provided on the base plate 102 can be a plunger 160 that comprises an operating force changing mechanism. As shown in FIG. 5, a coil spring 162 can be inserted into a cylindrical-shaped body of the plunger 160. Mounted at a tip end of the plunger 160 is a moving ball 164 connected to the spring 162. The moving ball 164 can be supported by the spring 162 such that when the moving ball 164 is pushed axially of the cylindrical-shaped body with a predetermined force or more, the spring 162 yields to the push force to contract with the result that the moving ball 164 retreats into the cylindrical-shaped body. On the other hand, when such push disappears, the spring 162 is elongated by elasticity and the moving ball 164 returns to an original position (see FIG. 5) at the tip end of the plunger 160.

On the other hand, insertion grooves 118 can be formed in two locations on the shift pedal 110 to correspond to the plunger 160 and to comprise the operating force changing mechanism. Specifically, the insertion grooves 118 can be formed in those positions to realize insertion of the moving ball 164 at the tip end of the plunger 160 into the insertion groove 118 when the shift pedal 110 is manipulated by a foot to turn (swing) vertically from the predetermined neutral position (position indicated by solid lines) in FIG. 4 to move to positions indicated by the dashed line and the two-dot chain line (respectively, referred below to as “shift-down bodily sensation signal generating position” and “shift-up bodily sensation signal generating position”).

That is, in the predetermined neutral position and in a position therearound, the moving ball 164 comes into pressure contact with a wall surface of the shift pedal 110 (the arm portion 112), and such pressure applies a predetermined torque on a foot (that is, a left foot operating a shift change) operating the shift pedal. On the other hand, when the shift pedal 110 moves to the shift-down bodily sensation signal generating position or the shift-up bodily sensation signal generating position, the moving ball 164 is inserted into the insertion groove 118. At the time of such insertion, torque required for operative movement of the shift pedal 110 is momentarily changed and further torque is momentarily changed when the moving ball 164 is once fixed in the insertion groove 118. Such change is transmitted as bodily sensation signal (that is, a signal can be perceived by sensation of the body (e.g., here, a foot). The same is applied below.) to a rider. Specifically, such torque change is perceived as feeling of click through a foot\'s sensation by a rider.

An explanation will be given to function and effect, which can be produced as a result of the construction of the embodiment described above at the time of shift change.

First, in order to change a transmission in speed, a rider can turn (swing) the shift pedal 110 upward or downward with a foot until the arm portion 112 of the shift pedal 110 abuts against the respective stopper pins 106, 107.

At this time, one 131A of the rods is pushed by the push portion 112D of the shift pedal 110 to be elastically deformed. When a manipulating force on the shift pedal 110 by a foot is released, the shift pedal 110 is returned to the neutral position (predetermined position) indicated by solid lines in FIG. 4 by an elastic force of the rod 131A. In addition, as described above, when the shift pedal 110 comes to the position (shift-down bodily sensation signal generating position) indicated by the dashed line or the position (shift-up bodily sensation signal generating position) indicated by the two-dot chain line in FIG. 4, feeling of click is gotten by the operating force changing mechanism (plunger 160) constructed in a manner described above.

Also, turning of the shift pedal 110 causes the turning plate 124 to turn via the latch pin 116. At this time, it is detected by the sensor 122 that the shift pedal 110 has been turned in a predetermined direction, and its signal is transmitted to the engine control unit. According to the illustrated embodiment, output of a detection signal from the sensor 122 and timing, in which feeling of click is gotten, are synchronized with each other. Thereby, a rider can perceive the start of speed change control processing through the feeling of click by sensation of a foot although the speed change operation is performed by a foot as compared with a hand.

Then the shift actuator 23B is operated by a signal from the engine control unit and the shift shaft 23 (FIG. 2) is turned in a predetermined direction.
