Abstract
A multi-spring system pressure plate member is provided for a spring biased clutch. The pressure plate member has a spring side and an opposed clutch side. The spring side of the pressure plate member includes spring confinement members for at least two clutch spring systems. The spring confinement members serve to hold spring members on said spring side in operative association with said pressure plate member. The spring confining members are provided to confine at least a diaphragm spring element and a compression coil spring element. The pressure plate member is configured to accept without modification either a diaphragm spring element or a set of compression coil spring elements. The clutch can be converted from one spring system to another by simply changing the spring elements.
Claims12
A clutch spring kit comprising:
- a pressure plate member, said pressure plate member having a spring side and a clutch side, and a spring confining member including at least a diaphragm spring confining member adapted to confining at least one diaphragm spring member on said spring side, and a compression coil spring confining member adapted to confining at least one compression coil spring member on said spring side;
- a plurality of shoulder bolt elements, said shoulder bolt elements being adapted to projecting axially slidably through said pressure plate member, said shoulder bolt elements being adapted to retaining at least one said compression coil spring member and/or at least one said diaphragm spring member on said spring side in spring biasing association with said pressure plate member;
- and
- at least one said diaphragm spring member.
A clutch spring kit comprising:
- a pressure plate member for a spring biased clutch, said pressure plate member having a spring side and an opposed clutch side, said pressure plate member including a spring confining member adapted to confining a spring member on said spring side in operative association with said pressure plate member, said spring confining member including at least a diaphragm spring element confining member and a compression coil spring confining member, and an array of axial bores extending through said pressure plate member;
- a plurality of shoulder bolt elements, said shoulder bolt elements being adapted to projecting generally axially and slidably through said array of axially bores and to being retentively associated on said spring side with said spring member;
- and
- said spring member comprising either at least one diaphragm spring element or at least one compression coil spring element, said spring member being adapted to resiliently biasing said pressure plate member in an axial direction that said clutch side faces.
A multi-spring system pressure plate member comprising:
- a said pressure plate member for a spring biased clutch, said pressure plate member having a spring side and an opposed clutch side, said pressure plate member including a spring confining member adapted to confining a spring member on said spring side in operative association with said pressure plate member, said spring confining member including at least a diaphragm spring element confining member and a compression coil spring element confining member.
