Automotive Clutch Bearings

Abstract

The invention discloses a vehicle clutch bearing, which comprises an inner ring, an outer ring, a plurality of balls arranged between the inner and outer rings, and a cage for holding the balls in a rotatable manner. A first sealing unit is arranged between them, one side end of the inner ring is formed with a radially inwardly extending inner ring rib, and one side end of the outer ring is formed with a radially inwardly extending outer Ring convex strip, a second sealing unit is arranged between the inner ring convex strip and the outer ring convex strip; the cage includes a front retaining piece and a rear retaining piece, the front retaining piece is located at the front end of the ball, and the rear retaining piece Located at the rear end of the ball, the front retaining piece and the rear retaining piece are connected by a connecting piece; the vehicle clutch bearing has a simple structure, can effectively seal, prevent external foreign matter from entering the bearing, and avoid the influence of high-speed centrifugal force, reducing torque loss.

Description

technical field [0001] The invention relates to a clutch sealing technology, in particular to a vehicle clutch bearing which can effectively prevent leakage and prolong service life. Background technique [0002] With the frequent use of vehicles, the importance of the clutch in the driving parts of the car has become more and more prominent, and the seal of the clutch is one of the keys to whether the clutch can withstand sufficient pressure and rotation speed. Therefore, the clutch such as The sealing part of the bearing is also becoming more and more important. The commonly used clutch bearings can be divided into the outer ring rotating in contact with the rotating parts of the clutch mechanism, such as diaphragm springs, and the inner ring fixed type and the inner ring and the clutch mechanism. The fixed outer ring / rotating inner ring type in which the rotating parts rotate in contact, and in the bearing, once water invades the inside of the bearing, it will affect the ...

AI Technical Summary

Problems solved by technology

And, when mud water intrudes into the gap between the outer ring and the inner ring at the rear side of the clutch release bearing, if the interference of the seal lip does not exist or the interference is small, the mud water passes through the inner ring and the seal The gap between the lips penetrates into the interior of the bearing to degrade lubricating oil such as grease, thereby shortening the life of the bearing

[0006] On the other hand, the seal on the rear side rotates with the outer ring, and due to the influence of centrifugal force in the high-speed rotation range, the interference of the sealing lip is sometimes lost, resulting in torque loss
