Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically relates to a long-service-life automotive shock absorber suspension bearing. Background Technology

[0002] Automotive suspension bearings are key components in automotive suspension systems that support rotating parts. Their main function is to ensure that the wheels rotate synchronously with the suspension system, maintaining vehicle stability and handling. They are usually located at the top of the front shock absorber and bear axial pressure.

[0003] The applicant originally designed a high-sealing automotive suspension bearing [Application No.: 202322157662.7; Authorization Announcement No.: CN220365868U], which includes an upper cover, a lower cover, and steel balls. The lower cover has an integral seal. The outer edge of the upper cover has a flange, and the bottom of the flange has an inwardly folded retaining edge. The outer wall of the lower cover has a radially outwardly convex ring. The seal has a sealing part that covers the convex ring. The sealing part has an outer sealing lip that is bent above the retaining edge. The bend of the outer sealing lip is located at its top. The outer sealing lip is in an interference fit against the inner wall of the flange. The lower cover has circumferentially distributed blind holes at the top of its inner edge. The seal has a connecting part fixed in the blind holes. The seal has an inner sealing lip that is in an interference fit against the inner wall of the inner edge of the upper cover.

[0004] The aforementioned high-sealing automotive suspension bearings have good anti-pull-out effect and good sealing performance. However, the core load-bearing components (such as the lower cover) are made of engineering plastics. Although plastic parts have the advantages of low cost and light weight, their compressive strength, fatigue resistance and long-term creep performance are limited. Under the harsh conditions of vehicles being subjected to severe impact loads and alternating stresses for a long time, these plastic parts are prone to plastic deformation, cracking and crushing. This has become one of the main reasons for the early failure and shortened service life of the entire suspension bearing. To solve the above technical problems, we have designed a long-service-life automotive shock absorber suspension bearing. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an automotive shock absorber suspension bearing that has strong load-bearing capacity, good deformation resistance, and a long service life.

[0006] The purpose of this utility model can be achieved through the following technical solution: a long-service-life automotive shock absorber suspension bearing, including a mounting base, a rubber vibration isolation seat mounted on the top of the mounting base, a load-bearing cup seat mounted on the top of the inner cavity of the rubber vibration isolation seat, a through hole opened at the bottom of the inner cavity of the load-bearing cup seat, a limit locking hole opened on the side wall of the inner cavity of the load-bearing cup seat, and a limit locking buckle fixedly connected to the side wall of the inner cavity of the rubber vibration isolation seat.

[0007] This long-life automotive shock absorber suspension bearing, through the combined use of mounting base, rubber vibration isolation base, limit hole, limit buckle and metal cup body, has the advantage of significantly improving service life. The load-bearing cup seat is cold-stamped carbon structural steel, and its higher strength and hardness ensure that it will not fail under extreme working conditions.

[0008] In the aforementioned long-service-life automotive shock absorber suspension bearing, the number of limiting holes and limiting buckles are the same and they are equidistantly distributed. The top of the inner cavity of the limiting buckle is chamfered, and the load-bearing cup seat is cold-stamped from carbon structural steel. By setting the limiting holes and limiting buckles, the load-bearing cup seat can be easily fixedly installed in the rubber vibration isolation seat.

[0009] In the aforementioned long-service-life automotive shock absorber suspension bearing, the bottom of the mounting base has a mounting hole, and a support ring is installed between the bottom of the inner cavity of the rubber vibration isolation seat and the load-bearing cup seat. The support ring facilitates support for the bottom of the load-bearing cup seat.

[0010] In the aforementioned long-service-life automotive shock absorber suspension bearing, the bearing cup seat includes a metal cup body. A raceway is formed on the top end face of the metal cup body, and an oil reservoir is formed on the outer side of the inner wall of the raceway. By providing the oil reservoir, more lubricating grease can be conveniently stored.

[0011] In the aforementioned long-service-life automotive shock absorber suspension bearing, an oil injection hole is provided on the side wall of the inner cavity of the oil reservoir, and a plug is threaded onto the inner cavity of the oil injection hole. By providing the oil injection hole, grease can be easily injected into the oil reservoir. The plug is made of hard rubber, and after being unscrewed from the oil injection hole, a grease injector can be used to add grease into the oil reservoir.

[0012] In the aforementioned long-service-life automotive shock absorber suspension bearing, a reinforcing rib is fixedly connected to the bottom of the metal cup body, and a sealing groove is formed at the bottom of the end face of the metal cup body, with a sealing gasket filling the inner cavity of the sealing groove. By setting the reinforcing rib, its compressive and deformation resistance can be greatly improved, and by setting the sealing gasket, the sealing performance between the metal cup body and the rubber vibration isolation seat can be increased.

[0013] Compared with existing technologies, this long-life automotive shock absorber suspension bearing, through the combined use of mounting base, rubber vibration isolation base, limit hole, limit buckle and metal cup body, has strong load-bearing capacity, good deformation resistance and long service life.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this long-life automotive shock absorber suspension bearing includes a mounting base 1, a rubber vibration isolation seat 2 mounted on the top of the mounting base 1, a load-bearing cup seat 3 mounted on the top of the inner cavity of the rubber vibration isolation seat 2, a through hole 6 opened at the bottom of the inner cavity of the load-bearing cup seat 3, a limit locking hole 4 opened on the side wall of the inner cavity of the load-bearing cup seat 3, and a limit locking buckle 5 fixedly connected to the side wall of the inner cavity of the rubber vibration isolation seat 2.

[0023] In actual manufacturing, the number of limiting holes 4 and limiting buckles 5 are the same and they are equidistantly distributed. The top of the inner cavity of the limiting buckle 5 is chamfered. The load-bearing cup seat 3 is cold-stamped from carbon structural steel. The bottom of the mounting base 1 is provided with mounting holes. A support ring is installed between the bottom of the inner cavity of the rubber vibration isolation seat 2 and the load-bearing cup seat 3.

[0024] In use, the load-bearing bowl 3 is cold-stamped from 08Al steel and carburized and quenched to achieve a surface hardness of HRC58-62, replacing the plastic parts in the original technology. It is installed in the inner cavity of the rubber vibration isolation seat 2 through the cooperation of the limiting buckle 4 and the limiting buckle 5. Its compressive strength and impact resistance are fundamentally improved, and it can withstand greater pressure and impact loads, fundamentally avoiding the risk of crushing and plastic deformation, and significantly extending its service life. Example 2

[0025] like Figure 4 , Figure 5 and Figure 6 As shown, the load-bearing bowl seat 3 includes a metal bowl body 14, a raceway 7 is provided on the top end face of the metal bowl body 14, and an oil storage groove 10 is provided on the outer side of the inner wall of the raceway 7.

[0026] In actual manufacturing, an oil injection hole 13 is provided on the side wall of the inner cavity of the oil reservoir 10, and a sealing head 9 is threadedly installed in the inner cavity of the oil injection hole 13. A reinforcing rib 8 is fixedly connected to the bottom of the metal bowl body 14, and a sealing groove 12 is provided at the bottom of the end face of the metal bowl body 14. The inner cavity of the sealing groove 12 is filled with a sealing gasket 11.

[0027] In use, a raceway 7 is machined on the top end face of the metal bowl body 14, making it the lower ring of the thrust bearing itself, eliminating a separate part and improving the system rigidity and precision. An annular oil reservoir 10 is opened on the side wall of the raceway 7 to store more grease. When the bearing starts working, due to temperature and vibration, the viscosity of the grease in the oil reservoir 10 decreases and becomes softer. The soft grease will slowly and continuously penetrate and spread to the main force-bearing raceway 7 to lubricate the rolling elements (steel balls) and extend the product life cycle.
