Novel damper suitable for automobile tail door electric push rod

Abstract

The invention provides a novel damper suitable for an automobile tail door electric push rod. The novel damper comprises a brake coupling, a brake outer sleeve, brake gaskets, a brake friction plate,a brake disc elastic piece and a brake threaded end cover, the brake outer sleeve, the brake gaskets, the brake friction plate, the brake disc elastic piece and the brake threaded end cover are arranged on the brake coupling in a sleeving fit mode, the inner space of the brake outer sleeve is of a structure with the wider upper portion and the narrower lower portion, the lower portion of the brakeouter sleeve is attached to the lower portion of the brake coupling, the two brake gaskets are located above the attaching portion between the brake coupling and the brake outer sleeve, the brake friction plate is arranged between the two brake gaskets, the brake disc elastic piece is arranged on the brake gaskets, and the brake threaded end cover is arranged on the brake disc elastic piece. Thenovel damper has the beneficial effects that the structure is simple and reasonable, the assembly efficiency is improved, the requirements of the assembly process and the height of the damper are reduced; and the strength of the structural material is relatively high, the service life is prolonged, and the universality of the product is improved.

Description

【Technical field】 [0001] The invention relates to an electric push rod damper for an automobile tailgate, in particular to a novel damper suitable for an electric push rod for an automobile tailgate. 【Background technique】 [0002] At present, the important structural parts of the one-way damper of the electric push rod of the automobile tailgate are large torsion spring and small torsion spring. The assembly process of large torsion spring and small torsion spring is difficult, and the height of the damper is relatively high; the material of the brake coupling is cast aluminum. The strength of the alloy material is low; the damper is installed by spin riveting, and the assembly requires spin riveting equipment. 【Content of invention】 [0003] The purpose of the invention is to solve the problems of difficult assembly process and low material strength of the current one-way damper of the electric push rod of the tailgate of the automobile, and provide a new type of damper ...
