Problems solved by technology

At present, the stabilizer bar can be divided into solid stabilizer bar and hollow stabilizer bar according to the structure of the raw material. The material of the hollow stabilizer bar is relatively expensive. Due to the limitation of the tooling or fixture of the pipe bending machine, the hollow stabilizer bar is not suitable for more complicated shapes.
The material cost of the solid stabilizer bar is lower, but the mass of the stabilizer bar is heavier, which is not conducive to the lightweight design of the vehicle

Embodiment 1

[0038] The invention relates to a vehicle stabilizer bar assembly, which includes a stabilizer bar body composed of a rod body and longitudinal arms symmetrically connected to two ends of the rod body, and an outwardly convex limiting portion is configured at the joint between the longitudinal arm and the rod body. The vehicle stabilizer bar assembly also includes a bushing fitted on the stabilizer bar body by fitting with the aforementioned limiting portion, and a stabilizer bar bracket clamped on the bushing. The vehicle stabilizer bar assembly constructs a protruding limiting portion on the stabilizer bar body, and inserts the bushing on the limiting portion. The integral structure of the limiting portion and the stabilizer bar body can avoid Disadvantages caused by installing retaining rings or clamps on the stabilizer bar body, and can also increase the contact area between the bushing and the stabilizer bar body, which is beneficial to improve the torsional stiffness of t...

Embodiment 2

[0048] This embodiment relates to a vehicle stabilizer bar assembly, which has substantially the same structure as that of the vehicle stabilizer bar assembly in Embodiment 1, except that Figure 8 As shown in , the limiting portion formed on the main body of the stabilizer bar in this embodiment is a rod body protrusion formed at the end of the rod body 1 , and the rod body protrusion can be formed at the end of the rod body 1 through a crimping process. At the end of the left trailing arm 2 there is also an embedded portion with the same outer diameter as the inner diameter of the rod body 1 , and the embedded portion can be formed at the end of the left trailing arm 2 by turning and milling. When the vehicle stabilizer bar assembly is assembled, the embedded part of the end of the left trailing arm 2 is embedded in the rod body 1, and the left trailing arm 2 and the rod body 1 are welded together, and then the groove on the bushing is aligned with the end of the rod body 1. ...

Embodiment 3

[0050] This embodiment relates to a vehicle stabilizer bar assembly, which has substantially the same structure as that of the vehicle stabilizer bar assembly in Embodiment 1, except that Figure 9 As shown in , the limit part formed on the main body of the stabilizer bar in this embodiment is a snap ring 7 snapped on the end of the rod body 1, and an outer diameter and an inner diameter of the rod body 1 are also formed at the end of the left longitudinal arm 2 The same embedded part, which can be formed at the end of the left trailing arm 2 by turning and milling process. When the vehicle stabilizer bar assembly is assembled, the embedded part at the end of the left trailing arm 2 is embedded in the rod body 1, and the left trailing arm 2, the rod body 1 and the snap ring 7 are welded together, and then the groove on the bush is aligned with the rod body The snap ring 7 at the end of 1 can be embedded and fitted. The above is an example of the limiting part on the side of t...

Abstract

The invention provides a vehicle stabilizer bar assembly. The vehicle stabilizer bar assembly comprises a stabilizer bar main body, which is formed by a bar body and longitudinal arms, wherein the longitudinal arms are symmetrically connected with the two ends of the bar body; convex limiting parts are arranged at the connected parts between the longitudinal arms and the bar body; and the vehicle stabilizer bar assembly further comprises a bushing and a stabilizer bar bracket, wherein the bushing is matched with the limiting parts in an embedded manner and sleeves the stabilizer bar main body, and the stabilizer bracket is clamped on the bushing. According to the vehicle stabilizer bar assembly, shortcomings in the prior art can be overcome to provide a stable and practical stabilizer bar assembly structure.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a vehicle stabilizer bar assembly. Background technique [0002] Existing car suspensions are generally designed to be relatively soft. When turning at high speeds, the vehicle body will generate large lateral roll and lateral angular vibration. In order to reduce lateral roll, a stabilizer bar is often added to the suspension. The stabilizer bar and the Shock absorbers are used in conjunction to provide additional stability to the vehicle. At present, the stabilizer bar can be divided into solid stabilizer bar and hollow stabilizer bar according to the structure of the raw material. The material of the hollow stabilizer bar is relatively expensive. Due to the limitation of the tooling or fixture of the pipe bending machine, the hollow stabilizer bar is not suitable for more complex shapes. The material cost of the solid stabilizer bar is low, but the mass of the stabilizer b...
