Torque-transmitting torque to thrust apply mechanism having amplified thrust |
摘要 |
A torque-to-thrust apply mechanism for a torque-transmitting mechanism includes an input electric motor supplying torque to a first rotary to thrust ball and ramp mechanism which converts rotary motion to an apply force between an apply plate and a plurality of friction discs within a torque-transmitting mechanism. The mechanism also includes a second rotary-to-thrust mechanism which receives input rotation from the first apply member as a result of reaction torque. The rotation of the second mechanism results in additional thrust on the friction plates to amplify the apply force of the torque-to-thrust apply mechanism.
