The upper edge of the stop block is provided with a notch, so that the stop block and the dustproof cover cap assembly form an avoiding structure of the upper support assembly. The surface coating of part of types of shock absorbers can be changed into electrophoresis, so that the salt spray resistance of surface protection is improved; meanwhile, the structure has high connection strength, and can avoid interference abnormal sound generated by deformation of the upper support assembly; the energy consumption in the production process is reduced; the assembly of the sliding column is simpler and more convenient, and the production efficiency is high; the applicability is stronger.
Description
Technical Field
The utility model relates to a dustproof cover cap connecting structure for a vibration absorber; the electrophoresis protection device is particularly suitable for carrying out electrophoresis protection on the shock absorber when the suspension structure and the process limit exist.
Background
The automobile shock absorber is a part of an automobile chassis, and the working condition of the automobile shock absorber is quite severe. Particularly, the surface protective coating is often damaged and corroded by various chemical reagents such as muddy water, sand, acid rain, snow melting agent and the like, the external factors are easy to cause the defects of the surface coating of the shock absorber, metal parts of the shock absorber are corroded and rusted, the metal strength is further reduced, even the shock absorber is rusted to cause serious safety accidents such as oil leakage and the like, and therefore the emphasis on protection is needed.
As shown in fig. 1, due to the structural limitation of the suspension, only a connecting screw, a dust-proof cover cap and a piston rod can be used for butt welding of some types of shock absorbers, the structure cannot perform electrophoresis protection on the shock absorbers due to the process technological limitation, only can perform electrostatic spraying on the whole shock absorbers after edge rolling and sealing, and is high in cost and complex in production process.
Disclosure of Invention
The utility model discloses a dustproof cover connection structure for shock absorber to solve among the prior art and work as having suspension structure and technology restriction, can't carry out the electrophoresis protection scheduling problem to the shock absorber.
The utility model comprises a shock absorber body, a spring, an upper support assembly, a dustproof cover, a piston rod, a connecting screw rod, a dustproof cover cap and a stop block; the dustproof cover is connected with the stop block to form a stop block and dustproof cover assembly; the inner holes of the stop block and the dustproof cover cap assembly are in clearance fit with the piston rod; the production process is simplified, and the defect that the structure of part of the shock absorbers cannot be subjected to electrophoresis is overcome.
The upper support assembly may slightly deform after the shock absorber works for a long time, and the edge of the upper part of the stop block is provided with a notch, so that the stop block and the dustproof cover assembly form an avoiding structure of the upper support assembly; deformation generated by the upper support assembly can be avoided, and abnormal sound generated by the sliding column assembly is avoided finally.
The dust cover is connected with a dust cover connecting structure of the electrophoresis protection in a press-fitting manner; the connection strength is about 10kN, and the use requirement of the shock absorber is completely met.
The utility model has the advantages of: the surface coating of part of types of shock absorbers can be changed into electrophoresis, so that the salt spray resistance of surface protection is improved; meanwhile, the structure has high connection strength, and can avoid interference abnormal sound generated by the deformation of the shock absorber; the energy consumption in the production process is reduced; the assembly of the sliding column is simpler and more convenient, and the production efficiency is high; the applicability is stronger.

Detailed Description
An embodiment of the present invention is described in detail below with reference to the accompanying drawings.
The embodiment of the utility model is shown in fig. 2 and 3, and comprises a shock absorber body 1, a spring 3, an upper support assembly 4, a dust cover 5, a piston rod 6, a connecting screw rod 7, a dust cover 8 and a stop block 9; the dustproof cover 8 is connected with the stop block 9 to form a stop block and dustproof cover assembly 2; the inner hole of the stop block and dust cover assembly 2 is in clearance fit with the piston rod 6; the production process is simplified, and the defect that the structure of part of the shock absorbers cannot be subjected to electrophoresis is overcome.
The upper support assembly 4 may slightly deform after the shock absorber works for a long time, and the upper edge of the stop block 9 is provided with a notch 9a, so that the stop block and the dust cover assembly 2 form an avoiding structure of the upper support assembly 4; abnormal noise of the strut assembly caused by deformation of the upper support assembly 4 can be avoided.
The dust cover 5 is connected with the dust cover connecting structure 2 for electrophoresis protection in a press-fitting manner; the connection strength of the dustproof cover connection structure 2 is about 10kN, and the use requirement of the shock absorber is completely met.
The utility model discloses can make and assemble according to conventional technology order and seal behind the 1 electrophoresis of shock absorber, behind the 2 electrophoresis protections of dustproof shroud connection structure, be in the same place dust cover 5 and 2 pressure equipments of dustproof shroud connection structure, then install on shock absorber body 1, install spring 3 again and go up support assembly 4.
