Description

A gas tightness detection device for car stabilizer bar assembly

Technical Field

The utility model belongs to the technical field of the gas tightness detection device, especially, relate to a gas tightness detection device for car stabilizer bar assembly.

Background

Stabilizer bars, also known as sway bars and stabilizer bars, are auxiliary elastic elements in vehicle suspensions, and in order to improve the ride comfort of a vehicle, the suspension stiffness is usually designed to be relatively low, which results in affecting the vehicle running stability. Therefore, a transverse stabilizer bar structure is adopted in the suspension system to improve the roll angle rigidity of the suspension and reduce the inclination angle of a vehicle body. The stabilizer bar serves to prevent the vehicle body from being excessively laterally tilted during turning, and to keep the vehicle body in balance as much as possible. The purpose is to reduce the lateral roll degree of the automobile and improve the smoothness. The stabilizer bar is in fact a torsion bar spring lying transversely and can be considered functionally as a special elastic element. When the vehicle body only moves vertically, the suspensions on the two sides deform the same, and the transverse stabilizer bar does not work. When the automobile turns, the automobile body inclines, the suspensions on the two sides jump inconsistently, the suspensions on the outer sides press the stabilizer bars, the stabilizer bars are twisted, and the elastic force of the rod bodies can prevent the wheels from being lifted, so that the automobile body keeps balance as much as possible, and the transverse stabilizing rod is used for increasing the rigidity of the inclination angle of the whole automobile if the rigidity of the inclination angle of the whole automobile is low and the inclination angle of the automobile body is too large. The stabilizer bars may be mounted on the front and rear suspensions individually or simultaneously as required. When designing a stabilizer bar, the roll angle rigidity ratio of front and rear suspensions should be considered in addition to the total roll angle rigidity of the entire vehicle. To provide understeer characteristics to the vehicle, the roll stiffness of the front suspension should be made slightly greater than that of the rear suspension. Therefore, in a relatively large number of vehicle types, a stabilizer bar is mounted on a front suspension.

The existing air tightness detection device for most of automobile stabilizer bar assemblies is easy to deviate when detecting the automobile stabilizer bar assemblies, and a mold can not be replaced according to different automobile stabilizer bar assemblies.
