  • Auxiliary-power-activated clutch and gear-shifting device
    Patent number: 5056632
    Abstract: Auxiliary power actuated clutch and gear shifting device for a motor vehicle transmission with function selector and a gear change mechanism controlled by the driver through a clutch actuating mechanism at the clutch pedal wherein a response signal to the driver is received when a gear is engaged in the transmission or the transmission is in neutral. Located at the clutch pedal and connected with it mechanically is a safety device that holds the actuated clutch pedal against movement when a gear is disengaged in the transmission during the shifting of gears. The safety device holds the clutch pedal clamped in actuated position until a gear is engaged in the transmission whence the driver can carry out the procedure of engaging the clutch again in known fashion. The safety device consists of a clamping mechanism that grips a piston rod connecting to the clutch pedal to prevent further operation until the clutch pedal is released.
