Abstract
A bearing carrier for a pull-type clutch, and which forms part of the clutch mechanism assembly, has a crenellated rim provided with longitudinally projecting tooth-like portions, cut-out portions being provided between consecutive projecting portions. A separate tubular member, forming part of the clutch control mechanism, has a correspondingly crenellated rim provided with longitudinally projecting portions and cut-out portions between consecutive projecting portions. One of the crenellated rims has a peripheral groove in which is disposed an expandable resilient ring, and the other crenellated rim has a corresponding peripheral groove and is provided at the leading edge of its projecting portion with a ramp for expanding the ring when the one of the crenellated rims is pushed into the other crenellated rim for coupling the bearing carrier with the tubular member during assembly of the bearing carrier with the tubular member. The clutch control mechanism is preferably an annular hydraulic cylinder having an annular piston attached to the other end of the tubular member. The annular cylinder, installed within the bell housing of the clutch mechanism, is connected to the master cylinder via a connector or a connection block fastened through an opening in the bell housing. The annular cylinder is connected to the connector or the connection block through a conduit disposed within the bell housing. A second conduit provided at an end with a complementary leak-proof connector member connects the connector or the connection block to the master cylinder.
