Abstract

The utility model discloses a polyurethane bushing assembly with retainer rings, which includes a middle shaft, an outer sleeve and an inner sleeve; the middle part of the middle shaft is sleeved with the inner sleeve; and a middle shaft support is arranged outside the inner sleeve, and is sleeved with the outer sleeve. The polyurethane bushing assembly has the structural characteristics that gaskets capable of buckling two sides of the inner sleeve are arranged on the middle shaft on two sides of the inner sleeve respectively, the outer side of each gasket on the middle shaft is buckled and fixed through an elastic retainer ring, an outer sleeve retainer ring is arranged on the inner side of the outer sleeve, an inner sleeve retainer ring is arranged on the outer side of the inner sleeve, and the outer sleeve retainer ring and the inner sleeve retainer ring are tightly embedded together into the middle shaft support. Therefore, the middle shaft, the outer sleeve and the inner sleeve can be tightly matched together, the displacement is difficult, the firmness is ensured, the release is avoided, and the service life is prolonged. The polyurethane bushing assembly has the characteristics of simple structure, prolonged service life, low possibility of release, etc.

Description

The polyurethane bush Assembly of band back-up ring

Technical field:

The utility model relates to a kind of automobile bush Assembly, relates in particular to a kind of polyurethane automobile bush Assembly with back-up ring.

Background technique:

Existing bush Assembly generally comprises axis, overcoat and interior cover, the interior middle part that is placed in axis, in interior cover outside is bottom bracket, bottom bracket is with overcoat outward, bottom bracket generally adopts the thermoplastic polyurethane material to make, owing to pressuredly between overcoat and interior cover and the bottom bracket tightly be connected, thereby have the fastness problem, easily generation comes off, and is not durable.

Summary of the invention:

The purpose of this utility model provides a kind of degree of balance height, the polyurethane bush Assembly of the band back-up ring of durable, wear-resisting and difficult drop-off.

The purpose of this utility model is to realize like this, the polyurethane bush Assembly of described band back-up ring, comprise axis, overcoat and interior cover, the interior middle part that is placed in axis, in interior cover outside is bottom bracket, bottom bracket is with overcoat outward, its structural feature is for respectively being provided with the pad that can fasten the cover both sides on the axis that is positioned at the cover both sides, each pad outside on the axis is withheld fixing by circlip, described overcoat inboard is provided with the overcoat back-up ring, cover back-up ring in the cover outside is provided with in described, the overcoat back-up ring closely is embedded in together with bottom bracket mutually with interior cover back-up ring.

The utlity model has following characteristics and advantage: the utility model makes axis, overcoat can closely cooperate with interior cover and is in the same place because overcoat back-up ring and interior cover back-up ring closely are embedded in bottom bracket, is difficult for displacement, does not firmly take off life-saving.Have characteristics such as simple in structure, ILS, difficult drop-off, be applicable to the automobile of various vehicles, irrigate, seize by force vehicles such as dragon, steyr, day dragon, Reynolds, iron-clad horses, Ou Man, Ao Wei, benz, a vapour, Second Automobile Works, Shan vapour, Shanghai Automobile Factory, heavy vapour, willow vapour as brave prestige, golden prince, person of outstanding talent, the bush Assembly of using as the automotive suspension device uses.
