Damping device with two-rider for lubricating for automobile

Abstract

The invention is a car damper with two guides and lubrication which can reduce the wear and enhance the damping effect. It includes an oil storing cylinder, a working oil cylinder is arranged in the oil storing cylinder, the bottom of the oil storing cylinder and the working oil cylinder are connected with bottom valve, a piston device is arranged in the working oil cylinder, the top of the working oil cylinder is arranged with a guiding cover and the second guiding cover, the two covers are covered out of the guiding bearing, a oil seal is arranged at top of the covers. The character is that tubes are arranged on the link shaft at two ends of the piston, interrupting spring bracket is arranged at two ends of the tube, interrupting spring is arranged on the interrupting bracket reversely, a oil storing slot is arranged on top of a guiding cover, a oil returning aperture penetrating the guide cover subjacent part on the cover, a ring slot is arranged on top of the second guide cover, a oil returning aperture is arranged on the inner wall of the ring slot, the guide cover oil returning aperture is connected to the second cover oil returning aperture.

Description

technical field [0001] The invention belongs to the field of automobile shock absorbers, in particular to a two-guided and lubricated automobile shock absorber. Background technique [0002] At present, automobile shock absorbers have a variety of structures, most of which are welded structures. The problem is that they can only be used once, and they are easy to wear and leak oil. In order to solve these problems, a kind of automobile shock absorber is introduced in the patent No. 99122594.5, and this shock absorber can solve the above-mentioned problems, and has better use value. But the lubricating performance of the second guide sleeve of this patent shock absorber is not good, and the oil storage capacity of the first guide sleeve is small, so the lateral friction force of the piston rod is large, and there is still the problem of fast wear and tear of parts. Contents of the invention [0003] The object of the invention is to provide a two-guided and lubricated auto...

AI Technical Summary

Problems solved by technology

[0002] At present, automobile shock absorbers have various structures, most of which are welded structures. The existing problems are that they can only be used once, and are easy to wear and leak oil.

However, the lubricating performance of the second guide sleeve of the patented shock absorber is not good, and the oil storage capacity of the first guide sleeve is small, so the lateral friction of the piston rod is large, and there is still the problem of fast wear of parts.
