Moreover, some of the above terms may be used to indicate other meanings besides the orientation or positional relationship, for example, the term "on" may also be used to indicate some kind of attachment or connection relationship in some cases. The specific meanings of these terms in the present invention can be understood by those skilled in the art as appropriate.
Furthermore, the terms "mounted," "disposed," "provided," "connected," and "connected" are to be construed broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; can be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The specific meanings of the above terms in the present invention can be understood by those of ordinary skill in the art according to specific situations.
Furthermore, the terms "first," "second," and the like, are used primarily to distinguish one device, element, or component from another (the specific nature and configuration may be the same or different), and are not used to indicate or imply the relative importance or number of the indicated devices, elements, or components. "plurality" means two or more unless otherwise specified.
In order to keep the vehicle body as balanced as possible, the stabilizer bar is an auxiliary elastic element in the vehicle suspension, which prevents the vehicle body from being excessively laterally tilted during cornering, and is generally mounted by connecting both end portions of the stabilizer bar to the left and right suspensions, the vehicle body, or the sub-frame, and by attaching the stabilizer bar to the vehicle body, the sub-frame, or the suspensions through bushings in the middle thereof.
When the automobile runs, if the left wheel and the right wheel jump up and down simultaneously, namely the automobile body only moves vertically and the suspensions on the two sides deform equally, the transverse stabilizer bar rotates freely in the bushing and does not work. When the suspensions on both sides are deformed differently and the vehicle body is inclined laterally with respect to the road surface, one side of the frame is moved closer to the spring seat, the end of the stabilizer bar on the side is moved upward with respect to the frame, the other side of the frame is moved away from the spring seat, and the end of the corresponding stabilizer bar is moved downward with respect to the frame. Thus, when the vehicle body is tilted, the longitudinal portions of both sides of the stabilizer bar are deflected in different directions, and the stabilizer bar is twisted, and the torsion internal moment generated by the stabilizer bar interferes with the deformation of the suspension spring, thereby reducing the lateral tilt and lateral angular vibration of the vehicle body. Wherein, the bush can play the effect such as shock attenuation noise reduction.
In the prior art, in order to prevent the stabilizer bar bushing from moving in the axial direction of the stabilizer bar, the stopper rings are generally provided on both sides of the bushing, and when the stabilizer bar bushing is used, the bushing is mounted on a subframe, a vehicle body or a vehicle frame, and then the rubber bushing and the stopper rings on both sides thereof are fitted over the stabilizer bar. However, when the car turns, the stabilizer bar functions, and the stopper rings on both sides of the bush are easily twisted and wear the bush due to the difference in frictional force between the brake ring and the bush and the stabilizer bar, resulting in a reduction in the life of the bush.
In view of the above, the present invention provides a stabilizer bar assembly including a stabilizer bar, a bushing, and a fixing seat; the stabilizer bar comprises a bar body and a limiting ring connected to the middle of the bar body, 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 axial section edge of the bar body; the bush sleeve is arranged on the outer side of the stabilizer bar in the circumferential direction, at least part of the inner wall surface shape of the bush is matched with the outer wall shape of the limiting ring, in addition, the bush can be contained in the fixing seat, the fixing seat can be fixedly arranged on the suspension structure, when the stabilizer bar acts, the limiting ring can limit the bush to transversely move along the stabilizer bar, and the stress inside the bush can be timely released due to the fact that the bush sleeve is arranged outside the limiting ring in a sleeved mode, abrasion between the limiting ring and the bush is weakened, and the service life of the bush is prolonged.
