Description

Technical Field

[0001] The present application relates to the technical field of automobile suspension, and in particular to a stabilizer bar assembly and a vehicle. Background Art

[0002] The stabilizer bar is an auxiliary elastic element installed in the suspension system of the car, which is used to increase the suspension roll angle stiffness and reduce the body roll angle, thereby preventing the body from excessive lateral roll when turning. The stabilizer bar is connected to the suspension of the car through bushings and clamps. The bushing is sleeved on the stabilizer bar, and the outer periphery of the bushing is wrapped and fixed by the clamp. The installation of the stabilizer bar is completed by fixing the clamp on the suspension.

[0003] In the prior art, the bushing is made of rubber material with low rigidity and low strength. During the torsional deformation of the stabilizer bar, the bushing is easily severely worn, thereby reducing the service life of the bushing and increasing the cost. When the clamp sleeve is arranged outside the bushing, the fitting surface of the clamp and the bushing is a plane, which cannot effectively limit the axial movement of the bushing. After repeated squeezing and pulling, the clamp is easy to twist or deform outward, and it is easy to produce abnormal noise, which affects the noise, vibration and acoustic roughness (English full name: Noise, Vibration, Harshness, abbreviated as: NVH) performance and ride comfort of the entire vehicle.
