Automobile suspension bushing and suspension

Abstract

The utility model discloses an automobile suspension bushing and a suspension. The automobile suspension bushing comprises an outer pipe, an outer rubber body, an inner rubber body and an inner pipe.An adjusting pipe is arranged between the outer rubber body and the inner rubber body, and limiting structures limiting each other are arranged on the section pipe and the outer pipe to limit the axial rotation amount of the inner pipe relative to the outer pipe. Under the condition that the vehicle makes a small turn or jolts slightly, the requirement of the vehicle for the suspension bushing ismet through the inner pipe, the adjusting pipe and the inner rubber body with the large rigidity. Under the condition of large turning or strong bumping of a vehicle, the shaft pin inner pipe penetrating through the inner pipe, the inner rubber body and the adjusting pipe rotate firstly, and the outer rubber body is driven to form a large bush after the shaft pin inner pipe, the inner rubber bodyand the adjusting pipe rotate to the adjusting pipe upper limiting structure and the outer pipe upper limiting structure to be combined in a protruding mode. Therefore, the large axial pull-out forcecan be met. Meanwhile, the large radial force requirement can be met, and the rigidity requirement and the comfort requirement are met.

Description

technical field [0001] The invention belongs to automobile chassis suspension components, in particular to a suspension bushing structure. Background technique [0002] Automobile suspension is the general term for the force transmission device between the frame and the wheel of the vehicle, and its function is to transmit the force and torque acting between the wheel and the frame. [0003] In the prior art, a general automobile suspension bushing includes an inner tube, an outer tube and a rubber body arranged between the inner tube and the outer tube, and a shaft pin is connected to the inner tube. When the vehicle is turning or the wheels are bumping, the suspension bushing will be affected by axial and radial forces, and the shaft pin will be pulled off and separated from the outer cylinder. Driving feel and the protective effect of the bushing on the suspension. Contents of the invention [0004] The invention provides an automobile suspension bushing and an automo...
