Antiseizing device of electromagnetic powder type clutch for vehicle

Abstract

Abstract PURPOSE:To inhibit seizing of a clutch for an automobile which is capable of starting in second gear, by inhibiting the second starting whenever its electromagnetic powder type clutch is heated due to frequent repetition of the second starting. CONSTITUTION:As an accelerator switch 40 is turned on in case of normal first gear starting, a given clutch current flows from a controller 38 to produce preset clutch torque with an electromagnetic powder type clutch 1, which gets the vehicle started smoothly. In case of starting in second gear, lack of any signal from a clutch temperature sensor 49, despite the second switch 50 being turned on, allows the vehicle get started. As the clutch temperature rises to a preset level due to frequent and repeated second gear starting, the sensor 49 issues a signal to increase the clutch current from the controller 38, which increases clutch torque to inhibit starting and an alarm buzzer 48 is sounded.
