Abstract
A rubber composite bushing of a plate spring support of a passenger car is a composite structure formed by vulcanizing an inner steel bushing and an outer steel bushing from an original pure rubber structure, wherein the inner steel bushing and the outer steel bushing are respectively bonded on the inner side surface and the outer side surface of a bushing rubber layer through rubber vulcanization. The utility model discloses a compound bush of passenger train leaf spring support rubber simple structure, during the use, the pressure that the round pin axle was applyed makes interior steel sheathing the latter half receive the ascending holding power of the latter half rubber, and the first half of interior steel sheathing receives the ascending pulling force of first half rubber simultaneously, and the round pin axle is applyed the power of steel sheathing including, through the effective dispersion relief pressure of vulcanized rubber buffering, improves the life of bush greatly.
Description
Technical Field
The utility model relates to a compound bush of passenger train leaf spring support rubber.
Background
The existing plate spring support bushing of the passenger car is made of natural rubber materials, and the bushing is frequently damaged by impact force exerted on the bushing by a pin shaft, needs to be frequently replaced, and is time-consuming and cost-consuming.
Disclosure of Invention
The utility model aims at providing a simple structure, long service life's compound bush of passenger train leaf spring support rubber.
The utility model discloses a compound bush of passenger train leaf spring support rubber is the composite construction who vulcanizes forming by inside and outside steel bushing with former pure rubber structure change into, vulcanizes through rubber on the inside and outside lateral surface on the bush rubber layer and bonds respectively and have inside steel bushing, outer steel bushing.
The utility model discloses a compound bush of passenger train leaf spring support rubber simple structure, during the use, the pressure that the round pin axle was applyed makes interior steel sheathing the latter half receive the ascending holding power of the latter half rubber, and the first half of interior steel sheathing receives the ascending pulling force of first half rubber simultaneously, and the round pin axle is applyed the power of steel sheathing including, through the effective dispersion relief pressure of vulcanized rubber buffering, improves the life of bush greatly.
