Actuating device for friction coupling in motor vehicle drive train between engine and gearbox has all components except compressed air source in housing bell cooling device for electronic controller

摘要

The device has a disengagement bearing arrangement, a pneumatically operated annular cylinder arrangement (6), a displacement sensor, a control valve (8), an electronic controller (10) and a compressed air source. All components apart from the compressed air source together with a temperature sensor are arranged in the housing bell. At least the electronic controller is acted upon by a cooling device depending on its controller temperature.
