The stabilizer bar is an auxiliary elastic element in an automobile suspension, and has the function of preventing the automobile body from excessively laterally rolling when the automobile turns, so that the automobile body is balanced as much as possible.
In the running process of the automobile, if the left wheel and the right wheel jump up and down at the same time, namely when the automobile body only moves vertically and the suspensions at two sides deform equally, the transverse stabilizer bar rotates freely in the bushing, and the transverse stabilizer bar does not act. When the two side suspensions are deformed unevenly and the vehicle body is inclined transversely to the road surface, one side of the vehicle frame moves closer to the spring support, the end of the side of the stabilizer bar moves upwards relative to the vehicle frame, the other side of the vehicle frame is far away from the spring support, the end of the corresponding stabilizer bar moves downwards relative to the vehicle frame, and when the vehicle body and the vehicle frame are inclined, the middle part of the transverse stabilizer bar does not move relatively to the vehicle frame. When the vehicle body is inclined, the longitudinal parts on both sides of the stabilizer bar deflect in different directions, so that the stabilizer bar is twisted, and the torsion internal moment generated by the stabilizer bar prevents the deformation of the suspension spring, thereby reducing the transverse inclination and transverse angular vibration of the vehicle body. Wherein, the bush can play shock attenuation noise reduction etc. effect.
In the prior art, in order to prevent the stabilizer bar bushing from moving along the axial direction of the stabilizer bar, stop rings are generally arranged on two sides of the bushing, and when the stabilizer bar is used, the bushing is mounted on an auxiliary frame, a vehicle body or a vehicle frame, and then the rubber bushing and the stop rings on two sides of the rubber bushing are sleeved on the stabilizer bar. However, when the automobile turns, the stabilizer bar acts, and the stopper rings on both sides of the bushing are liable to twist and abrade the bushing due to the difference in friction between the stopper rings and the bushing and the stabilizer bar, resulting in a reduction in the life of the bushing.
In view of the above, the present invention provides a stabilizer bar assembly comprising a stabilizer bar, a bushing and a fixing base; the stabilizer bar comprises a bar body and a limiting ring connected to the middle part of the bar body, wherein the limiting ring circumferentially surrounds the outer side of the bar body, and the outer wall of the limiting ring is arc-shaped along the section edge of the bar body in the axial direction; the bush cover is established in the circumference outside of stabilizer bar, and the outer wall shape phase-match of at least part internal face shape and the spacing ring of bush, in addition, the bush can be acceptd in the fixing base, and fixing base can fixed mounting on suspended structure, and when the stabilizer bar action, the spacing ring can restrict bush along stabilizer bar lateral shifting, and because the bush cover is established outside the spacing ring, the inside stress of bush can in time release for wearing and tearing between spacing ring and the bush weaken, the bush life-span is improved.
