20060194667 - Pressing device for tensioning two gearing elements, gearing provided with a pressing device of this type, and method for operating such a friction gearing: A press-on apparatus including two press-on apparatus parts for two gear members running together is proposed, with the second press-on apparatus part partially accommodating the force applied by the first press-on apparatus part....

20060194668 - Traction drive power transmission device: A traction drive power transmission device, where a lubrication oil can be stably and continuously applied for a long period to portions at which rollers and a shaft are in contact with each other, shortage of the lubrication oil does not occur at the contact portions, the lubrication oil is...

20060194669 - Variator disk and variator for a toroidal transmission: What is proposed is a variator disk for a toroidal variator, in particular for a motor vehicle toroidal transmission. The variator disk has a curved running surface which is oriented coaxially with respect to a variator axis and on which rollers of the toroidal variator can roll. The variator disk...

20060189434 - Transmission: A transmission includes: a casing of the transmission; a shaft rotatably supported by the casing and having an oil passage; plural gears mounted on the shaft. The lubricant is partly lifted and stirred in response to a shift operation implemented by selectively engaging and rotating the gears. The transmission further...

20060189435 - Variator and variator arrangement: A variator for a toroidal transmission, with a driving disk and with a driven disk, between which is set up a toroidal space which defines a toroidal reference circle. The variator, further, comprises at least two rollers which are arranged in the toroidal space for torque transfer between the driving...

20060183594 - Variable speed drive for a continuously variable transmission: A friction ring variable speed drive with a continuously variable transmission ratio. A concavely curved first transmission element is rotatable around a first axis of rotation and a convexly curved second transmission element is rotatable around a second axis of rotation. The first and second transmission elements receive between them...
