The transverse stabilizer bar in the front suspension system of automobile usually interferes with the body or the fixed parts of the body through the conical buffer. Therefore the stabilizer bar bushing assembly and the stabilizer bar installation should be able to effectively limit the stabilizer bar transverse channeling The function of the rubber door buffer is to prevent the body from turning too much lateral roll. The purpose is to prevent lateral tilting and improve ride comfort. The lateral stabilizer bar is a torsion bar spring made of spring steel. It is shaped like a "U" and is placed horizontally on the front and back end of the car. The middle part of the rod body is hinged with a sleeve and the frame and the two ends of the rod are respectively fixed on the left and right hanging lower brackets or shock absorber sliding column. The appearance of rubber sleeves can reduce friction.
