Description

Technical Field

[0001] This utility model belongs to the field of release bearing technology, and specifically relates to a sealed clutch release bearing. Background Technology

[0002] The clutch release bearing, installed between the clutch and transmission in a manual transmission vehicle, is a crucial component for disconnecting or connecting the power system and requires excellent self-aligning performance. During vehicle operation, the driver depresses or releases the clutch pedal according to driving conditions. Force is transmitted to the clutch release bearing, which alters the force on the diaphragm spring to engage or disengage power. Damage to the clutch release bearing can endanger the driver and the vehicle.

[0003] Currently, the sealing structure of commonly used clutch bearings on the market is a common sealing ring. Because the outer ring wall of this bearing is very prone to deformation during machining and heat treatment, the fit between the sealing ring and the outer ring sealing groove often becomes too loose. Furthermore, due to the special installation location and relatively large external vibrations, this bearing frequently detaches during use, leading to abnormal bearing failure due to sealing problems. Utility Model Content

[0004] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing a sealed clutch release bearing to ensure that the product has good sealing performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sealed clutch release bearing includes an outer ring, an inner ring, a cage, and rolling elements. Multiple rolling elements are tactilely disposed between the outer ring and the inner ring, and all rolling elements are tactilely connected to the cage. The bearing also includes a housing and an elastic seal, both of which are annular structures. The housing is snap-fitted to the end of the outer ring, and the inner side of the housing is fixedly connected to the outer side of the elastic seal. The inner side of the elastic seal presses against the inner ring.

[0006] To better realize this utility model, the above structure is further optimized. The middle part of the cover is a U-shaped structure and wraps around the end of the outer ring. The outer side of the cover is snapped into the bend of the outer ring.

[0007] To better realize this utility model, the above structure is further optimized, and the cover is made of cold-rolled steel.

[0008] To better realize this utility model, the above structure is further optimized by providing a slot on the outer side of the elastic seal and inserting the inner side of the cover into the slot for fixed connection.

[0009] To better realize this utility model, the above structure is further optimized, and the elastic seal is made of nitrile rubber.

[0010] To better realize this utility model, the above structure is further optimized by providing a retaining ring at the end of the inner ring.

[0011] To better realize this utility model, the above structure is further optimized by including a bushing and a top cover. One end of the top cover is fixedly connected to the bushing, and the other end is movably connected to the inner ring. A spring washer is provided between the top cover and the inner ring.

[0012] To better realize this utility model, the above structure is further optimized. The bushing is made of plastic material, and the upper cover is fixedly connected to the bushing with a snap fastener.

[0013] Compared with the prior art, this utility model has the following advantages: The sealed clutch release bearing provided by this utility model combines the housing and the elastic seal into a whole. After the housing is rolled, it fits tightly with the outer ring, which has a very large locking force. This ensures that the elastic seal will not loosen or rotate due to rotation or force, and keeps the sealing lip of the elastic seal in good contact with the outer diameter of the inner ring, ensuring that the product has good sealing performance.
