Push type self-aligning hydraulic release bearing wheel cylinder unit

Abstract

The invention discloses a push type self-aligning hydraulic release bearing wheel cylinder unit, relating to a vehicular release bearing unit. The push type self-aligning hydraulic release bearing wheel cylinder unit is especially suitable for passenger cars and commercial vehicles using push type clutches, in particular cars using the push type clutches and belongs to the technical field of automobile bearings. The push type self-aligning hydraulic release bearing wheel cylinder unit comprises a self-aligning bearing mechanism, a hydraulic wheel cylinder mechanism and an air bleeder, wherein the self-aligning bearing mechanism consists of an outer ring, an inner ring, a retainer, a steel ball, an inner dustproof cover, an outer cover, an aligning leaf spring, a sleeve and a sleeve seat; the hydraulic wheel cylinder mechanism consists of a cylinder body, a mandrel, a leather ring, a mandrel sealing ring, a return spring and a spring seat; and the air bleeder comprises an oil feeding connector, a clamp, a first O-shaped ring, a second O-shaped ring, an exhaust valve tee joint, an air bleed screw sealing ring, an air bleed screw, an air bleed screw cap, an air feeding connector screw and a choke plug. The push type self-aligning hydraulic release bearing wheel cylinder unit disclosed by the invention has the use function of the release bearing and the function of the wheel cylinder and is hydraulically driven. The push type self-aligning hydraulic release bearing wheel cylinder unit has the advantages of higher service efficiency, longer service life and higher flexibility in operation.

Description

technical field

[0001] The push-type self-aligning hydraulic release bearing sub-pump unit of the present invention relates to a release bearing unit for vehicles, which is especially suitable for passenger cars and commercial vehicles using push clutches, especially cars using push clutches, and belongs to Automotive bearing technology field. Background technique

[0002] The working principle of the traditional automobile clutch is divided into two types, one is the mechanical pull bar mechanism: step on the clutch pedal, pull the shift fork through the pull bar, the shift fork pushes or pulls the release bearing to separate the active and passive friction plates of the clutch, cut off The power output of the engine, so as to realize the clutch function. The other is a hydraulic transmission mechanism: step on the clutch pedal, the power is transmitted to the clutch master cylinder, the master cylinder outputs oil pressure to the slave cylinder, the slave cylinder pushes ...
