technical field

The invention belongs to the technical field of front pillar assemblies of vehicles, and in particular relates to a positioning structure of a mounting seat on a front pillar and a hub package assembly and an automobile.

Background technique

In the automobile suspension system, the front pillar mount is the connecting structure between the front pillar and the body, and it is also used to absorb the impact of the front suspension of the car from the road and reduce vibration, accelerate the attenuation of the vibration of the frame and the body, and improve the quality of the car. Transition parts for ride comfort. It affects the dynamic performance of the suspension to a certain extent, and then affects the handling stability and ride comfort of the vehicle.

The front pillar generally includes dampers, springs, buffer blocks, upper mounts, spring pads, etc. The mounting seat on the front pillar is connected with the hub package of the car body through bolts and nuts.

In the traditional vehicle assembly process, the structure with bolts on the upper mounting seat requires manual hand support to complete the final assembly of the vehicle, or the structure with nuts on the upper mounting seat requires additional tooling to assist manual assembly of the front pillar assembly and the vehicle body. These two structures are unable to satisfy the robot automatic assembly of the front suspension and the car body.

Contents of the invention

The purpose of the present invention is to provide a positioning structure for the mounting seat on the front pillar and the hub package assembly and an automobile. The outer body of the upper mounting seat and the rough positioning hole are matched with each other through the protrusion in the middle of the mounting seat body, and the matching installation The seat body is fixedly arranged on the same side of the upper mounting seat shell and the positioning pins are matched with the fine positioning holes to complete the mutual positioning of the front pillar upper mounting seat and the car body hub package, and then solve the robot automation of the front suspension as a whole and the car body Fitting positioning problem.

For realizing above-mentioned technical purpose, the technical scheme that the present invention adopts is as follows:

A positioning structure of a mounting seat and a hub package assembly on a front pillar, comprising a car body hub package and a mounting seat body fixedly connected to the vehicle body hub package, the mounting seat body is a hollow structure, and the middle part of the mounting seat body faces The outer casing of the upper mounting seat is formed by protruding in the direction away from the hub of the car body. The body of the mounting seat is fixed with positioning pins on the same side of the outer casing of the upper mounting seat. Coarse positioning holes that match, and fine positioning holes that match the positioning pins are also provided on the hub of the vehicle body.

It is further defined that a rubber bushing is provided in the mounting seat body, the mounting seat body and the rubber bushing are in interference fit, the rubber bushing is provided with a bushing inner skeleton, and the mounting seat body is in the rubber bushing A support ring is fixed below the sleeve, and an upper cover plate of the mounting seat is fixed above the rubber bushing inside the mounting seat body. Such a structural design completes the fixing of the rubber bush through the fixed connection of the support ring, the upper mounting seat cover plate and the mounting seat body, which has a simple structure and strong practicability.
