Clutch apparatus for vehicle

Abstract

Abstract PURPOSE: To prolong life of clutch, eliminating unnecessary half-clutch condition, by using engine revolution number signal and also car speed signal with hysteresis having difference in power output area at speed increasing and speed reducing time, as clutch control signal. CONSTITUTION: Output power of revolution number sensor 140 is inputted to f-V conversion circuit 201 via rectagular wave rectifying circuit 200. According to the comparison of output power voltage with fixed voltage, when revolution number is less than lower side fixed value N 1 , [H] signal is outputted from comparison circuit 262 as a signal, and when revolution number is exceeded higher side fixed value N 2 , then [H] signal is outputted from comparison circuit 204 as b signal. On the otherhand, comparison circuit 204, 205 make comparison on upper limit and as well lower limit of allowable area of torque conductivity of clutch, and comparison circuit 209 make comparison on high and low car speed side fixed value V 1 , V 2 with output power of car speed sensor 110. Its theoretical circuit 400 serves for connection control of torque transmission when no output of signal from comparison circuit 209 is made. COPYRIGHT: (C)1980,JPO&Japio
