Problems solved by technology

[0002] Leaf springs are widely used in heavy-duty automobile balance suspension and passenger car leaf spring suspension systems, and the leaf spring and the frame hanger are connected through a bushing; currently, the bushing used to connect the leaf spring and the frame hanger is mainly Rigidly connected bimetallic bushings are used. This kind of bimetallic bushings is expensive to manufacture and inconvenient to install. Lubricating oil needs to be applied between the pins, bushings and lifting lugs during vehicle operation, and it is prone to abnormal noise. At the same time, due to the load Too large, easy to wear and cause damage, can not meet the operating requirements

Abstract

A shaft housing for a heavy vehicle equalizing suspension and a bus leaf spring suspension comprises metal core shafts, a spacer bush, a shell, baffle rings and two layers of elastic rubber bodies, wherein the spacer bush is positioned between the two layers of elastic rubber bodies; the metal core shafts, the spacer bush, the shell and the elastic rubber bodies are integrally vulcanized; and the elastic rubber body of the inner layer is longer than that of the outer layer in an axial direction so as to ensure that the stressed surfaces of the elastic rubber bodies of the two layers are equal and that stress applied to the elastic rubber bodies of the two layers is equal. The shaft housing is characterized in that: the shell, the spacer bush and the elastic rubber bodies are circumferentially disconnected, namely, nicks are reserved on the spacer bush and the elastic rubber bodies, and the nicks reserved on the shell, the spacer shell and the elastic rubber bodies are open C-shaped groove nicks; the baffle rings are arranged on the core shafts on the two sides of the axial direction of an elastic body formed by the spacer bush and the elastic rubber bodies; the inner circles of the baffle rings are tightly sleeved on the core shafts, while periphery is arranged in the shell; and a certain gap is reserved between each baffle ring and the shell.

Description

technical field [0001] The invention belongs to an elastic damping component and its assembly method, in particular to an elastic bush product used between the leaf spring of the heavy-duty automobile balance suspension and the bus leaf spring suspension system and the suspension lug of the vehicle frame and its production The assembling method is mainly used in heavy-duty automobile balance suspension and bus leaf spring suspension system, and can be extended to steel plate guide arm suspension system. Background technique [0002] Leaf springs are widely used in heavy-duty automobile balance suspension and passenger car leaf spring suspension systems, and the leaf spring and the frame hanger are connected through a bushing; currently, the bushing used to connect the leaf spring and the frame hanger is mainly Rigidly connected bimetallic bushings are used. This kind of bimetallic bushings is expensive to manufacture and inconvenient to install. Lubricating oil needs to be a...
