Abstract:
A system for altering the bias of a clutch spring in and for thus changing the condition of an engageable and disengageable friction clutch between a rotary output element of a prime mover and a rotary input element of a change-speed transmission having a composite transmission housing and being disposed in the power train of a motor vehicle, comprising:a primary unit having an output; means for actuating said primary unit to thus transmit a pulse by way of said output; a clutch release device having an at least partially plastic composite casing and a mobile bearing coaxial with said input element and arranged to alter the bias of said clutch spring in response to movement axially of said input element; and means for operatively connecting said output with said device to move said bearing axially of said input element in response to actuation of said primary unit to transmit a pulse by way of said output; wherein said device is coupled to said transmission housing in a place that is axially opposite said bearing, the coupling of said device to said housing being effected by a direct engagement between said plastic composite casing and said housing.
