Description

A connection structure for a front stabilizer bar bracket of an automobile

technical field

The utility model belongs to the field of automobiles, in particular to a connection structure between a front auxiliary frame and a front transverse stabilizer bar of a small electric vehicle.

Background technique

The car front stabilizer bar is an important part of the car suspension system. It has the function of balancing and stabilizing the coordinated movement of the left and right suspension devices. For the existing cars that use McPherson suspension as the front axle suspension, the stabilizer bar is generally used to directly connect the subframe, but this connection method will produce damage during driving and braking. A large torsional moment causes relatively severe vibration, which affects the connection strength of the stabilizer bar.

Based on this, there is a need for a structure that can meet the needs of small electric vehicles to enhance the connection strength of the front subframe and the stabilizer bar, and meet the layout requirements while ensuring the connection strength of the subframe and the stabilizer bar.

Utility model content

The purpose of this utility model is to overcome the above-mentioned problems, and propose a connection structure for the front stabilizer bar bracket of a small electric vehicle, which has the advantages of simple structure, small space occupation and low cost while improving the connection strength of the front sub-frame and the stabilizer bar. The advantage of being low, thus leaving enough space for the arrangement and installation of the associated mechanism and peripheral components, which is convenient for arrangement and installation.

The technical scheme of the utility model includes a front sub-frame assembly with left and right longitudinal beams and a front and rear beam enclosing structure, the front beam of the assembly is connected with the two ends of the front transverse stabilizer bar

Then, the stabilizer bar bracket is fixed on the supporting surface surface of two identical 7-shaped mounting brackets arranged on the upper surface and the rear surface of the front beam, and the mounting brackets are respectively welded on the upper surface and the rear surface of the front beam to reduce the occupied space, Facilitate the installation of other components.

In order to further improve the connection strength, the upper surface of the mounting frame is lapped and welded to the support surfaces on the left and right sides through the rear flanging.

Further, in order to facilitate the installation of the front stabilizer bar bracket, two installation through holes are opened on the upper surface of the installation bracket, and two square projection welding nuts are welded on the lower surface of the installation bracket for connecting the bolts and the front stabilizer bar bracket to fix the front transverse stabilizer bar.
