  • Hydraulic clutch release mechanism for motor vehicles
    Patent number: 4069904
    Abstract: A hydraulic release mechanism for automotive clutches and the like comprising a housing and a bearing assembly. The assembly comprises a non-rotating race ring, a rotatable race ring adapted to be connected to an operating element for said clutch and a plurality of rolling elements arranged therebetween. The bearing assembly is mounted with respect to the housing for axially slidable movement and radially floating movement. The housing under pressure, the force of which is transmitted through the end of the non-rotating race ring, the rolling elements, and the rotating race ring to the clutch operating element. Preferably, the means for mounting the bearing assembly with respect to said housing comprises a flexible bellows.

  • Hydraulic release mechanism for clutches
    Patent number: 3970177
    Abstract: A hydraulic release mechanism for automobile clutches comprising a housing open at one end and a bearing. The bearing comprises a rotating race ring adapted to be connected to the operating member of the clutch, a non-rotating race ring and a plurality of rolling elements located therebetween. The non-rotating race ring is slidably arranged with respect to the housing, and seal means is arranged between the housing and the axial frontal end of the non-rotating race ring to enclose space between the sliding surfaces while permitting the race ring to move on introduction of pressurized fluid into the housing.
