Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a shock absorber rubber bushing assembly. Background Art

[0002] The shock absorber rubber bushing assembly plays an important role in the automobile shock absorption system, such as absorbing and reducing vibration, separating the vibration source and protecting other components. It is one of the key components to ensure the smooth, comfortable and safe driving of the vehicle.

[0003] In the prior art, for example, the Chinese patent number is CN219119692U, "A shock absorber rubber bushing assembly", which includes a main body. After injecting lubricating oil into the interior of the storage box and pressing it, the limit block is engaged and connected to the interior of the limit slot to form a limit. At this time, the lubricating oil slowly flows down through the baffle ring and is discharged outward through the flow cotton to flow between the main body and the pin rod. The operation is simple. The main body can be lubricated in real time through this mechanism to ensure the stable performance of long-term operation, and it can also effectively avoid the situation where the lubricating oil is consumed too quickly and needs to be added multiple times; by pushing up the dust blocking frame and placing it inside one end of the main body and engaging the top block to the inside of the tooth groove, the U-shaped plate is pushed outward by the elastic folding plate to prevent loosening. At this time, the dust is guided by the guide plate and flows to the inner side of the dust blocking frame and is adsorbed by the adsorption cotton. The simple structure can effectively prevent excessive dust from entering the interior to increase friction and ensure the subsequent use effect.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that when installing the rubber bushing assembly on the shock absorber, the shock absorber needs to be completely disassembled, and then the rubber bushing assembly needs to be put on the shock absorber, which reduces the installation efficiency, prolongs the failure time, and increases the work intensity of the maintenance personnel. At the same time, when installing the rubber bushing assembly, the above dustproof device also needs to be removed before the rubber bushing assembly can be installed, which further reduces the installation efficiency of the rubber bushing assembly, further prolongs the failure time and increases the work intensity of the maintenance personnel.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1.

When the dust cover 1 rotates in the opposite direction, the spring 1 obtains elastic potential energy, and then the fixing block is inserted into the limiting groove 1. Because the width of the limiting groove 1 is limited, the clamping block makes a circular motion with the fixing rod as the center, and drives the spring 2 to rotate, so that the spring 2 obtains elastic potential energy. Then, when the clamping block moves to the limiting groove 2, At this time, the space of limit groove one is increased so that limit groove one no longer hinders the card block, and spring two releases elastic potential energy to make the card block rotate. Finally, the card block will rotate in limit groove two, and then the dust cover one will no longer rotate. At this time, spring one releases elastic potential energy to make the card block tightly stuck in limit groove two, so that dust cover one and dust cover two can be separated and fitted by rotating dust cover one, which is convenient for replacement of rubber sleeve, further improving installation efficiency, reducing maintenance time, and further reducing the workload and failure time of maintenance personnel.

[0034] Working principle: This device is a shock absorber rubber bushing assembly. When installing, first install the positioning pin 1 on the shock absorber. When the positioning pin 1 is installed, the mainspring 13, the dust cover 12 and the dust cover 2 11 are also installed. At first, the dust cover 12 and the dust cover 2 11 are separated, and the dust cover 2 11 can move up and down on the outer surface of the positioning pin 1. Then manually rotate the liner 2 and the rubber sleeve 7 so that the installation groove 1 5 on the liner 2 and the installation groove 2 8 on the rubber sleeve 7 are at the same position. Then manually pry apart the liner 2 and the rubber sleeve 7 to increase the space between the installation groove 1 5 and the installation groove 2 8. Then use the space between the installation groove 1 5 and the installation groove 2 8 to install the liner 2 and the rubber sleeve 7 on the positioning pin 1. Then When the liner 2 is manually rotated, the installation groove 1 5 on the liner 2 and the installation groove 2 8 on the rubber sleeve 7 are not in the same position. The rotation of the liner 2 drives the multiple slide bars 6 to move on the inner surface of the multiple slide grooves 9. The notch 3 is filled with graphite powder. Graphite powder is an excellent lubricating material with good wear resistance and high temperature stability. It can maintain the lubrication effect inside the rubber sleeve 7. The material of the lubricating layer 4 is polytetrafluoroethylene. Polytetrafluoroethylene has excellent wear resistance and low friction coefficient. It can be used to coat the inside of the liner 2 to reduce friction and wear. The steel wire 10 can increase the rigidity of the rubber sleeve 7 and increase the service life of the rubber sleeve 7. In this way, the liner 2 and the rubber sleeve 7 can be quickly installed on the positioning pin 1, which improves the installation efficiency and reduces The labor intensity of the maintenance personnel is reduced and the failure time is reduced. After the lining 2 and the rubber sleeve 7 are installed on the positioning pin 1, the dust cover 12 and the dust cover 2 11 are moved close, and the dust cover 12 is manually rotated in the opposite direction to align the fixing block 20 on the dust cover 12 with the limiting groove 17. When the dust cover 12 rotates in the opposite direction, the spring 13 obtains elastic potential energy, and then the fixing block 20 is inserted into the limiting groove 17. Because the width of the limiting groove 17 is limited, the block 16 makes a circular arc motion with the fixing rod 14 as the center, and drives the spring 2 15 to rotate, so that the spring 2 15 obtains elastic potential energy. Then, when the block 16 moves to the limiting groove 2 18, because the space of the limiting groove 17 is increased at this time, the limiting groove 1 7 no longer hinders the block 16, the spring 2 15 releases the elastic potential energy to make the block 16 rotate, and finally the block 16 will rotate in the limit groove 2 18, and then the dust cover 1 12 will no longer rotate. At this time, the spring 13 releases the elastic potential energy to make the block 16 tightly stuck in the limit groove 2 18. The anti-corrosion layer 19 is made of epoxy resin, which usually has good adhesion and wear resistance, and can effectively protect the dust cover 1 12 and the dust cover 2 11 from external erosion. In this way, the dust cover 1 12 can be separated and fitted with the dust cover 2 11 by rotating the dust cover 12, which is convenient for replacing the rubber sleeve 7, further improving the installation efficiency, reducing the maintenance time, and further reducing the work intensity and failure time of the maintenance personnel.
