Power transmitting system for automotive vehicle, incorporating automatically-operated constant-mesh transmission and clutch device |
摘要 |
An automatic power transmitting system operatively connected to an engine of an automotive vehicle, having a constant-mesh transmission with at least one synchromesh device which is operated by an actuator device to selectively establish a plurality of gear positions. The system includes a first and a second clutch which are disposed in parallel relation with each other, between between the engine of the vehicle and the constant-mesh transmission. The first clutch has a one-way clutch operable to transmit an output of the engine to the constant-mesh transmission, and is engaged while the vehicle is in a normal drive mode. The second clutch is engaged while the vehicle is in an engine brake mode. Each synchromesh device is operated to effect a shifting operation after the opening of the throttle valve of the engine is reduced, and without disengaging the first clutch before the operation of the synchromesh device.
