Embodiment Construction

[0010] attached by figure 1 It can be seen that the present invention includes a dust cover 1 and a buffer block 2 provided in the dust cover 1, and a piston rod 3 is provided in the buffer block 2, and the dust cover 1 and the buffer block 2 are integrally structured.

[0011] In the invention, the original blow molding process dust cover and the injection molding process rubber buffer block are rationally improved and designed. Its structure abandons the previous clamping structure, and changes it to a part that uses rubber integral injection molding. In the present invention, the dust cover 1 and the buffer block 2 are designed as an integrated structure, which can be obtained directly by injection molding process, and the original production efficiency is shortened. The original material is replaced with rubber to improve the impact resistance of the dust cover 1 itself and prolong the service life. Due to the integrated structure design, the dust cover 1 and the buffer...

Abstract

The invention provides a shock absorber dustproof-cover and buffer block integrated injection molding structure and relates to shock absorber dustproof-cover and buffer block integrated improvement. The shock absorber dustproof-cover and buffer block integrated injection molding structure comprises a dustproof-cover and a buffer block arranged in the dustproof-cover, wherein a piston rod is arranged in the buffer block; the dustproof-cover and the buffer block are integrally formed. The shock absorber dustproof-cover and buffer block integrated injection molding structure has the benefits as follows: the conventional clamping structure is eliminated and the part obtained by integrated injection molding of rubber is used, so that good coaxiality of the dust-cover and the buffer block is ensured and the compatibility of the shock absorber dustproof-cover and buffer block integrated injection molding structure and the piston rod is improved.

Description

technical field [0001] The invention relates to an integrated improvement of an automobile shock absorber dust cover and a buffer block. Background technique [0002] In recent years, due to the deepening of people's understanding of cars, the requirements for car safety, comfort and stability are also increasing. As an important part of the automobile suspension system, the shock absorber has a significant impact on the above performance. The working condition and environment of the shock absorber in the actual driving of the vehicle are generally complicated and harsh. Therefore, good dust-proof sealing performance can improve the service life and safety performance of the shock absorber. The original structure is as figure 2 As shown: the dust cover needs to be produced by blow molding process, the production cycle of the part is long and the stress and impact resistance is insufficient, which is prone to cracking, damage and other problems. In the actual assembly pro...
