Description
Technical field
The present invention relates to technical field of automobile parts, in particular to a kind of vehicle stabilizer bar assembly.
Background technique
Existing automotive suspension is typically designed softer, run at high speed turn to when, vehicle body can generate very big lateral roll
And Traverse angular vibration often adds stabiliser bar to reduce lateral inclination in suspension, stabiliser bar is used cooperatively with damper,
To provide additional stability for running car.Currently, stabiliser bar can be divided into solid stabilizing rod and hollow according to raw material structure
Stabiliser bar, hollow stabilizing rod material is more expensive, and because bending machine tooling or fixture limit, hollow stabilizing rod should not also be realized more
Complicated shape.Solid stabilizing rod material cost is lower, but stabiliser bar heavier mass, is unfavorable for the light-weight design of vehicle.Separately
On the one hand, it is the axial limiting for realizing stabiliser bar upper bushing structure, needs to increase retaining ring or yoke configurations on stabiliser bar.Using gear
When coil structures, retaining ring need to be inserted on stabiliser bar before stabilizer bar end molding, when carrying out bead to stabiliser bar, retaining ring portion
Point stabiliser bar can not direct bead, need stabiliser bar overturn after carry out secondary bead.And when using yoke configurations,
Stabiliser bar axial direction pulling-out force is smaller, is easy to appear and pulls phenomenon.
Summary of the invention
In view of this, the present invention is directed to propose a kind of vehicle stabilizer bar assembly is provided with overcoming deficiency in the prior art
A kind of stabilization, practical stabiliser bar assembly structure.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
