Description

Technical Field

[0001] The utility model relates to the technical field of retaining frames, in particular to a built-in retaining frame structure for a vehicle ball cage. Background Art

[0002] The automotive ball cage cage is one of the key components in the automotive drive system. It is mainly used to hold and support the rolling elements (such as spherical bearings) in the ball joint to ensure the smooth rotation of the drive shaft.

[0003] Patent No. CN216895440U discloses a ball cage retainer, belonging to the field of ball cage technology. The patent includes a frame, a steel ball hole is opened on the outer wall of the frame, an oil injection hole is opened on the side wall of the frame, and a diversion hole is opened on the outer wall of the frame. The frame is provided with an oil storage component and a circulation sealing component inside, the oil storage component is connected to the oil injection hole, and the circulation sealing component is connected to the diversion hole. The patent uses the oil storage component and the circulation sealing component in combination to allow the lubricating grease in the oil storage tank to flow into the steel ball hole through the oil outlet groove, and the use of oil storage cotton can absorb excess lubricating grease in the steel ball hole. The oil storage cotton can be squeezed during the rotation of the steel ball to keep the steel ball in a lubricated state for a long time, saving lubricating grease. At the same time, the lubricating grease can be transported to the outer wall of the frame, reducing the friction between the retainer and the outer wheel, and increasing the service life of the device.

[0004] As shown in the above technology, a common ball cage retainer is installed inside the ball cage. The retainer helps to keep the rolling elements in their working position and prevent them from contacting each other, thereby ensuring smooth rotation. However, the internal lubricating oil is affected by gravity. During operation, the lubricating oil is easily deposited at the bottom of the ball cage for a long time, and the surface lubrication is limited. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a built-in retainer structure for a vehicle ball cage, which solves the problem that lubricating oil is easily deposited on the bottom of the ball cage for a long time during operation, resulting in limited surface lubrication.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a built-in retainer structure for a vehicle ball cage, comprising:

[0007] The retainer body has a ball receiving groove on its side, a ball bearing groove on its top and bottom, and the inner ring and outer ring of the retainer body are polished smooth.

[0008] Preferably, a warp groove is formed on the inner wall of the retaining frame body, and the inner wall of the warp groove is roughened.

[0009] Preferably, heat dissipation holes are provided on the surface of the retainer body, and the heat dissipation holes are provided in a plurality and are evenly arranged on the surface of the retainer body.

[0010] Preferably, the surface of the ball receiving groove is fixedly connected with an annular edge, the material of the annular edge is aluminum oxide, and the aluminum oxide sheet is bonded using industrial adhesive.

[0011] Preferably, a wear-resistant edge is fixedly connected to the surface of the ball bearing groove, and the material of the wear-resistant edge is chromium-nickel alloy, which is connected by welding.

[0012] The utility model provides a built-in retainer structure for a vehicle ball joint. Compared with the prior art, it has the following advantages:

[0013] (1) The built-in retainer structure used in the automobile ball cage utilizes the arrangement of the ball receiving groove, the ball bearing groove, and the warp groove. The inner wall of the retainer is designed to be concave. The concave structure can reduce the contact area with the ball, thereby reducing the friction coefficient. The concave structure can help evenly distribute the lubricant and improve the lubrication effect. The grooves can increase the surface area, help dissipate heat, and reduce the heat generated by friction. The concave grooves can enhance the structural strength of the retainer to a certain extent and provide better support effect.

[0014] (2) The built-in retainer structure used in the automobile ball cage utilizes the setting of annular edges and wear-resistant edges to have good wear resistance to withstand repeated friction of the rolling elements, extend the service life, facilitate fine processing, maintain a smooth surface to reduce the friction coefficient, reduce energy loss and wear, and the geometric shape and size need to be precise to ensure good fit with the rolling elements and ensure smooth movement.
