Adjustable hydraulic clutch release bearing assembly with inner ring rotation

Abstract

The invention discloses a center-adjustable hydraulic clutch release bearing assembly with a rotating inner ring and belongs to an automobile part. An existing hydraulic clutch release bearing assembly is short in service life, and dust easily falls into a rolling channel. The center-adjustable hydraulic clutch release bearing assembly comprises a hydraulic oil cylinder and a release bearing, wherein the hydraulic oil cylinder comprises an outer cylinder wall, an inner cylinder wall and a plunger piston, and the release bearing comprises an outer ring, an inner ring, a rolling body, a retainer and a sealing ring. The center-adjustable hydraulic clutch release bearing assembly is characterized in that a sleeve body is assembled on the plunger piston, the release bearing can be assembled on the sleeve body in a radial center-adjusting mode, and the outer end face of the inner ring is a friction face in contact with a clutch press disc spring piece. When the assembly works, the inner ring rotates with a clutch press disc, the contact circulation service life of the rolling body can be prolonged (about 20%-30%), the dust-proof bearing sealing can be improved, and waste falling into the rolling channel of the bearing can be decreased.

Description

technical field [0001] The invention belongs to auto parts, in particular to a center-adjustable hydraulic clutch release bearing assembly with an inner ring rotating. Background technique [0002] The existing hydraulic clutch release bearing assembly such as figure 1 As shown, the outer ring of the release bearing rotates with the clutch pressure plate. Under the premise of other inconveniences, at the same clutch pressure plate speed, the number of contact cycles of the rolling elements when the outer ring of the bearing rotates is about 30% more than that of the rolling elements when the inner ring of the bearing rotates, that is to say, the number of contact cycles of the rolling elements when the outer ring rotates The theoretical life of the bearing is about 20-30% shorter than that of the inner ring rotating bearing. [0003] In addition, the clutch pressure plate is in contact with the outer end surface of the outer ring of the bearing, and it is very easy to push...
