- the two shafts can be connected.
- the joint force is high before the joining of the second joint surface having a low joint force is completed. Since the joining of the first joining surface is completed, shock due to the joining of the first joining surface is unlikely to occur, and the connection is completed because the entire joining is completed by the smooth joining of the second joining surface with low joining force There is no shock.
- the torque transmitting member rotates at a rotational speed that is delayed from the output shaft of the engine by the torque of the magnetic drag. For this reason, at the time of shifting, the torque transmitting member does not have an inherent inertial force and follows the output shaft of the engine. As a result, the rotational speed difference between the torque transmitting member and the first clutch member is It tends to be smaller, and joining of the first joining surface becomes easier.
- the magnetic drag generated between the second clutch member and the torque transmitting member generates creep when stopped, and can be used for starting on a slope and smooth starting.
- the torque transmitting member is interposed between the second clutch member and the first clutch member, the application of the load by the load applying means is released, and if the joining of the first joining surface is released, the first The clutch member is not affected by the inner clutch of the second clutch member and the torque transmitting member connected to the output shaft of the engine. For this reason, the inertia of only the first clutch member is applied to the synchronization mechanism, and no excessive load is generated. This places a burden on the synchronization mechanism of the transmission. Since no shift is given, extremely quick shifting can be completed. Industrial applicability
- the starting device is provided between the transmission and the engine, and is used for connection and disconnection between the transmission and the engine.
- the engine may be any driving force generating device such as an internal combustion engine or an electric motor.
- the transmission includes not only a stepped transmission but also a continuously variable transmission.
