Abstract:
A clutch engaging and disengaging apparatus comprising:a driving mechanism being configured to rotate to engage and disengage a clutch with said clutch engaging and disengaging apparatus; a motion converting mechanism having a push rod having first and second ends, said motion converting mechanism being configured to convert rotational motion of said driving mechanism into linear motion; a load storing mechanism being configured to store a load when said motion converting mechanism moves linearly in a first direction, said load storing mechanism being configured to release said load when said motion converting mechanism moves linearly in a second direction; and a hydraulic mechanism being configured to use said linear motion of said motion converting mechanism to produce hydraulic pressure and engage or disengage the clutch, said hydraulic mechanism being configured to be pushed by said first end of said push rod, said load storing mechanism having a spring being connected to said motion converting mechanism, said spring being extendable and compressible in response to said linear motion of said motion converting mechanism, said load storing mechanism having a support member being configured to support an axially facing end part of said spring, said spring being arranged on said second end of said push rod, and said spring being configured to push said rush rod toward said hydraulic mechanism.
