Multipurpose spiral spring installation base

Abstract

The invention relates to a multipurpose spiral spring installation base which comprises a positioning plate, an installation supporting frame connected with one side of the bottom face of the positioning plate and a connection part of which the upper end portion is connected with the other side of the bottom face of the positioning plate and the lower end portion is connected with one side of the installation supporting frame. A protrusion is arranged at one end portion on the positioning plate. The protrusion is in interference fit with the lower portion of a spring support. Two buffering seat positioning holes are formed in the other end portion on the positioning plate. The section of the installation supporting frame is in an inverted U shape. Two inner sides of the installation supporting frame are fixedly connected with two outer sides of a vehicle body carling. The upper face of the spring support abuts against the lower end of a spiral spring. The two buffering seat positioning holes correspond to two through holes in a buffering seat respectively and connected and fixed through a threaded fastener. According to the multipurpose spiral spring installation base, the spiral spring and the buffering seat can be installed, the number of vehicle body parts is reduced, the positioning precision of the parts is improved and welding is convenient.

Description

technical field [0001] The invention relates to an automobile chassis suspension system, in particular to a multipurpose coil spring mounting seat. Background technique [0002] With the continuous improvement of people's living standards, the requirements for the operability, safety and ride comfort of the car are getting higher and higher. For the car whose chassis suspension system adopts the coil spring structure, the installation structure of the coil spring is usually connected with the The other installation structures of the body are independent, and the structural form is relatively simple. It is often ensured by increasing the thickness of the part material and increasing the weld seam connecting with the body to ensure sufficient rigidity and fatigue strength. The rear buffer seat is usually also independent of other installation structures of the vehicle body. Such a structure not only increases the number of vehicle body parts, but also makes welding operati...

AI Technical Summary

Problems solved by technology

And the rear buffer seat is usually independent from other installation structures of the car body. Such a structure not only increases the number of car body parts, but also makes the welding operation inconvenient due to too many weld connections, which is not conducive to the improvement of production efficiency.

For example, the invention patent with the notification number CN 102166934 A discloses a rear coil spring installation structure of the chassis suspension system. Although this structure can well play the functions of buffering and position limiting, the coil spring and the rear buffer seat respectively adopt The installation structure increases the difficulty of assembly for workers, which is not conducive to improving production efficiency. In addition, its positioning accuracy is also difficult to control
