JPS60191828A - Mechanism for controlling torque vibration of vehicle - Google Patents

Abstract

PURPOSE:To prevent easily a clutch from the occurrence of judder when torque vibration corresponding to the judder from a transmission and the clutch is detected, by controlling the clutch to the semi-clutched condition. CONSTITUTION:When a clutch 12 is turned on, the power of an engine 11 is transmitted to rear wheels 16 through the clutch 13, a transmission 13, a propeller shaft 15, etc. Then, when torque vibration such as judder is caused by the low speed rotation of the engine 11, knocking, etc. rotation fluctuation is detected in a control circuit 33 for receiving voltage signals corresponding to engine rotation generated from a DC tacho-generator 18. When voltage proportional to the fluctuation exceeds a predetermined value, a solenoid in an actuator mechanism 31 is excited so that a rod 26 in a sleeve cylinder 25 projects to set the clutch 12 to the semi-clutched condition through a release lever 20.
