Description

Technical Field

[0001] This utility model relates to the technical field of vibration dampers, and in particular to a guide seat assembly. Background Technology

[0002] Shock absorbers are devices designed to reduce vibrations between the vehicle frame and body, improving ride comfort. Most car suspension systems include shock absorbers. The structure of a shock absorber consists of a piston rod inserted into an oil-filled cylinder. A guide is a guiding device at the cylinder's sealing point, guiding the piston rod during its movement. To prevent oil leakage through the gap between the guide and the piston rod, an oil seal is typically installed inside the guide seat. The oil seal is fixed by an oil seal pressure plate, usually using a flanged design, which is a relatively complex method. Utility Model Content

[0003] The purpose of this invention is to provide a guide seat assembly, which aims to solve the problem of the cumbersome method of fixing the oil seal pressure plate in existing shock absorbers.

[0004] To achieve the above objectives, this utility model discloses a guide seat assembly, including a guide seat body, an oil seal, and an oil seal pressure plate. The guide seat body has a T-shaped receiving cavity, the oil seal is disposed in the receiving cavity, and the upper end face of the oil seal abuts against the end face of the receiving cavity. The oil seal pressure plate is disposed on the lower end face of the oil seal and is accommodated in the receiving cavity. The lower end face of the receiving cavity has a plurality of rivet points, which constrain and fix the oil seal pressure plate.

[0005] Preferably, the guide seat body, the receiving cavity, the oil seal, and the oil seal pressure plate are all coaxially arranged; all the rivet points are arranged in a ring around the axis of symmetry of the oil seal pressure plate.

[0006] Preferably, there are four rivet points.

[0007] Preferably, an annular groove is formed on the upper end surface of the oil seal pressure plate; the annular groove is located between the outer side wall and the inner side wall of the oil seal pressure plate.

[0008] The beneficial effects of this utility model are as follows: When installing the guide seat assembly provided by the above technical solution, the oil seal and oil seal pressure plate can be placed in the receiving cavity first, and then the lower end face of the receiving cavity can be riveted to form a number of riveting points. The riveting points constrain and fix the oil seal pressure plate. The fixing method is relatively simple and solves the problem that the fixing method of the oil seal pressure plate in the existing shock absorber is relatively cumbersome.

[0017] refer to Figures 1 to 3A guide seat assembly includes a guide seat body 100, an oil seal 120, and an oil seal pressure plate 130. The guide seat body 100 has a T-shaped receiving cavity. The oil seal 120 is disposed in the receiving cavity, and the upper end face of the oil seal 120 abuts against the end face of the receiving cavity. The oil seal pressure plate 130 is disposed on the lower end face of the oil seal 120 and is received in the receiving cavity. The lower end face of the receiving cavity has a plurality of rivet points 140, and the rivet points 140 constrain and fix the oil seal pressure plate 130. During installation, the oil seal 120 and oil seal pressure plate 130 can be placed in the receiving cavity first. At this time, the lower end face of the receiving cavity is slightly protruding from the lower end face of the oil seal pressure plate 130. The inner wall of the lower end face of the receiving cavity is riveted using tooling and a riveting machine. Several riveting points 140 are formed downward and inward on the inner wall of the lower end face of the receiving cavity. The riveting points 140 constrain and fix the oil seal pressure plate 130. The fixing method is relatively simple and solves the problem of the cumbersome fixing method of the oil seal pressure plate in the existing shock absorber.

[0018] In one embodiment, the guide seat body 100, the receiving cavity, the oil seal 120, and the oil seal pressure plate 130 are all coaxially arranged; all the rivet points 140 are arranged in a ring around the axis of symmetry of the oil seal pressure plate 130. The guide seat body 100, the receiving cavity, the oil seal 120, and the oil seal pressure plate 130 are all provided with through holes for piston rod movement. The guide seat body 100, the receiving cavity, the oil seal 120, and the oil seal pressure plate 130 are all coaxially arranged, and all the rivet points 140 are arranged in a ring around the axis of symmetry of the oil seal pressure plate 130. All the rivet points 140 apply a relatively balanced constraint and fixing force to the oil seal pressure plate 130, reducing the risk of the oil seal pressure plate 130 falling out of the receiving cavity.

[0019] In one embodiment, there are four rivet points 140. The four rivet points 140 are equidistantly spaced to apply a more balanced constraint and fixing force to the oil seal pressure plate 130, reducing the risk of the oil seal pressure plate 130 falling out of the receiving cavity.

[0020] In one embodiment, an annular groove 131 is formed on the upper end face of the oil seal pressure plate 130; the annular groove 131 is located between the outer side wall and the inner side wall of the oil seal pressure plate 130. The oil seal 120 is generally made of rubber. When the piston rod moves, the oil seal 120 may deform, causing the oil in the cylinder to leak outward from the guide cavity. The annular groove 131 formed on the upper end face of the oil seal pressure plate 130; the annular groove 131 is located between the outer side wall and the inner side wall of the oil seal pressure plate 130. The annular groove 131 can match the lower end face of the oil seal 120, reducing the movement space of the oil seal 120, reducing the possibility of deformation of the oil seal 120, and further reducing the risk of oil in the cylinder leaking outward from the guide cavity.

[0021] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
