Abstract
In a power transmission apparatus, a sub-clutch apparatus is arranged between the input shaft and an intermediate rotary body, a main clutch apparatus is arranged between the intermediate rotary body and the output shaft, and a cam apparatus converting the frictional engagement force of the sub-clutch apparatus into the pressing force for the main clutch apparatus.
Claims4
A power transmission apparatus arranged between an input shaft and an output shaft, so as to execute a torque transmission comprising:
- a sub-clutch apparatus arranged between the input shaft and an intermediate rotary body and operated by an electric current application, so as to be frictionally engaged, thereby executing a torque transmission between the input shaft and the intermediate rotary body;
- a main clutch apparatus arranged between the intermediate rotary body and the output shaft and frictionally engaged by a pressing force, thereby executing a torque transmission between the intermediate rotary body and the output shaft;
- and
- a cam apparatus arranged and constructed to convert the frictional engagement force of the sub-clutch apparatus into the pressing force for the main clutch apparatus.
