AUTOMOBILE GEAR-CHANGING APPARATUS WITHOUT CLUTCH PEDAL

摘要

A guide hole is drilled in a touching part (2) of a gear change lever (1) and a pressing unit (4a) with a coil spring (5) is positioned in the guide hole. A plate (4) is attached to the inner of the hole to apply electric current to switching terminals (3)(3'). A piston rod (12a) of an oil cylinder (11) is connected to an operating lever (17) of a clutch unit (16), and oil to be supplied to the oil cylinder through a solenoid hydraulic valve (7) is pumped by a oil pump (13). Exhaust ports (7a)(7b)(7c) of a hydraulic valve (7) is selectively closed and opened by a relay unit (6) so that when an operator touches the touching part, the operation of change speed is performed without the action of clutch pedal.
