Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic clutches, in particular to a novel release bearing for a hydraulic clutch. Background Art

[0002] The clutch release bearing is a relatively important part on the car. If it fails due to poor maintenance, it will not only cause economic losses, but also be quite troublesome to disassemble and assemble, which takes a lot of man-hours. Therefore, it is important to find out the cause of the clutch release bearing failure and perform reasonable maintenance and care during use to extend the life of the release bearing and improve labor productivity. The release bearing can make the release lever rotate while moving along the clutch output axis, ensuring that the clutch can engage smoothly, making the separation softer and reducing wear, thereby extending the service life of the clutch and the entire transmission system.

[0003] At present, a release bearing is required in a hydraulic clutch to enable a release lever to rotate and move at the same time. Existing release bearings are mostly riveted, which are not very strong and have many parts. The more parts there are, the more quality problems there are. Utility Model Content

[0019] In the utility model, firstly, the original riveted structure is cancelled, and the integral casting method is directly adopted, and the position of the oil inlet guide hole is directly reserved to avoid the oil leakage during use. After casting, the housing and the bearing are connected by a return spring, and the sealing ring is further entered into the slide groove and slides by the injected oil, thus avoiding the problem of low firmness caused by riveting. In addition, because the casting method reduces the number of parts, the fewer the parts, the fewer the quality problems. BRIEF DESCRIPTION OF THE DRAWINGS
