Description

Shock absorber buffer block guide structure

Technical Field

The utility model relates to a bumper shock absorber technical field specifically is a shock absorber buffer block guide structure.

Background

The damping system is one of the important systems of the automobile, and influences the operating stability and the comfort of the automobile. It typically contains dampers, springs, bumpers, bushings, etc. In many vehicle models, shock absorbers and shock absorbers are assembled together. One of them is mounted on the shock absorber, and the dust cover is mounted on the shock absorber. Because the buffer block and the piston rod have a certain gap, the structure causes the inclination and the deviation of the buffer block to cause the interference of the dust cover and the shock absorber cylinder in the moving process of the automobile, thereby causing the abnormal abrasion of the dust cover, the oil leakage of the shock absorber and other faults. In order to solve the problem, the invention designs a guide structure for the buffer block of the shock absorber to prevent the buffer block from generating inclined deviation.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The shock absorber buffer block guide structure comprises a buffer block mounting seat 1 and is characterized in that a buffer block 2 is fixedly mounted at the lower end of the buffer block mounting seat 1, the buffer block mounting seat 1 and the buffer block 2 are respectively sleeved on a piston rod 3, a clamping convex edge 4 is arranged on the outer surface of the buffer block 2, the clamping convex edge 4 is in a circular ring shape, a dust cover 5 is clamped on the clamping convex edge 4, a shock absorber liquid storage cylinder 6 is arranged at the lower end of the dust cover 5, the piston rod 3 is inserted into the shock absorber liquid storage cylinder 6, a plurality of layers of bulges 7 are arranged on the inner wall of the buffer block 2 along the vertical direction, the cross section of each bulge 7 is semicircular, the diameter of the semicircle is R, the diameter of the piston rod 3 is R, and R = R +0.1 mm.

Preferably, the buffer block mounting seat 1 and the buffer block 2 are fixedly connected by gluing. The bulges 7 are provided with 3 layers, and a plurality of bulges 7 are uniformly distributed on each layer along the radial direction of the inner wall of the buffer block 2. The protrusion 7 and the buffer block 2 are integrally formed. Still be equipped with on the buffer block mount pad 1 and bordure 8, buffer block mount pad 1 is the type setting with bordure 8 an organic whole.

The utility model discloses a realize like this, through increasing protruding 7 in buffer block 2 inside, protruding 7 positions set up with 2 integrated into one piece of buffer block. The total number of the layers is 3, and 4 layers are uniformly distributed in each layer. The interval radian of the structures of the adjacent bulges 7 on the same layer is pi/4, and the diameter of a circle formed by the cross section of the bulges 7 on the same layer is 1mm larger than the diameter of the piston rod 3. These projections 7 can guide the buffer block 2, and effectively prevent the buffer block 2 from being tilted. And the buffer block 2 is integrally formed, so that the structure is simple and the cost is low. Meanwhile, the design does not influence the performance of the buffer block 2 and the liquid storage cylinder 6 of the shock absorber and does not occupy other spaces.

The above-described embodiments are illustrative of the present invention and not restrictive, it being understood that various changes, modifications, substitutions and alterations may be made herein without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
