Planetary Gear Transmission Systems Or Components > With Means To Vary Drive Ratio Or Disconnect Drive (e.g., Brake Or Clutch) > Plural Elements Selectively Braked > Transmission Includes Three Relatively Rotatable Sun Gears > With Brake For Sun, Carrier And Orbit With Brake For Sun, Carrier And OrbitWith Brake For Sun, Carrier And Orbit patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.02/22/07 - 20070042858 - Electrically variable transmission having three planetary gear sets and two fixed interconnections and a stationary interconnection The electrically variable transmission family of the present invention provides low-content, low-cost electrically variable transmission mechanisms including first, second and third differential gear sets, a battery, two electric machines serving interchangeably as motors or generators, and up to five selectable torque-transfer devices, and possibly a dog clutch. The selectable torque ... 10/05/06 - 20060223666 - Transmission, in particular an automated power-branched multi-speed gearing A transmission (1) is proposed, especially an automated power-split multi-speed transmission, comprises at least three power branches (P1, P2, P3), which are each connected to a shaft (2, 3, 4) of a downstream planetary gearset (5) and are configured with at least one partial transmission ratio (i1, i2, i3). Each ... 08/10/06 - 20060178243 - Planetary transmissions having two non-continuously interconnected gear members The family of transmissions has a plurality of members that can be utilized in powertrains to provide at least eight forward speed ratios and one reverse speed ratio. The transmission family members include three planetary gear sets having seven torque-transmitting mechanisms and three interconnecting members. The powertrain includes an engine ... 07/06/06 - 20060148610 - Planetary transmissions having two interconnecting members and clutched input members The family of transmissions has a plurality of members that can be utilized in powertrains to provide at least eight forward speed ratios and one reverse speed ratio. The transmission family members include three planetary gear sets having seven torque-transmitting mechanisms and two interconnecting members. The powertrain includes an engine ... 06/15/06 - 20060128517 - Multi-stage automatic transmission with three planetary gearwheel assemblies A multi-stage automatic transmission comprises a drive input shaft (AN), a drive output shaft (AB), three planetary gearwheel assemblies (RS1, RS2, RS3) arranged next to one another in series and five shift control elements (A to E). A sun gearwheel (SO3) of the third planetary gearwheel assembly (RS3) can be ... 06/01/06 - 20060116233 - Electric drive axle An electric drive axle, which is located between and powers the left and right drive wheels of an automotive vehicle, includes an electric motor and left and right torque couplings. Torque developed by the motor transfers through the torque couplings to axle shafts which are connected to the drive wheels. ... 02/02/06 - 20060025275 - Six-speed powertrain of an automatic transmission A variable compound planetary gearset forms five operational elements by having its single and double pinion planetary gearsets be interconnected by a shared planet carrier. The variable compound planetary gearset forms six forward speeds and one reverse speeds by receiving input torque through two input routes fixedly or variably connected ... 11/24/05 - 20050261102 - Multi-step transmission A multi-step transmission comprises an input and output shaft arranged in a housing, three spider supported planetary gear sets, seven rotatable shafts; six switch elements; input occurs via a shaft, in connection with the planet carrier of the first planetary gear set, output occurs via a shaft, in connection with ... ### FreshPatents.com Support |
