Front suspension control arm

Abstract

A front suspension control arm comprises a control arm body which is integrally stamped and formed, The control arm body extends to the inside of the vehicle body with first and second connecting armsconnected to the subframe, the overhanging ends of the first and second connecting arms are arranged along the front and rear directions of the vehicle body, the control arm body extends to the outside of the vehicle body with a third connecting arm connected to the steering knuckle, and the arms of the first, second and third connecting arms are provided with a reinforcing plate. The invention adopts the structure of plate stamping and forming combined with reinforcing plate, which not only ensures the strength of the control arm, but also effectively reduces the weight of the control arm, reduces the production cost, and improves the processing efficiency and the finished product rate. By setting the space structure of the control arm body reasonably, the front axle load of the whole vehicle can be satisfied with 700-1000Kg, so as to realize the universalization of multi-vehicle models and wide application.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension systems, and in particular relates to a front suspension control arm. Background technique [0002] The control arm of the front suspension of the car belongs to the suspension guide part, which is used to connect the subframe and the steering knuckle, not only to transmit the load on the steering knuckle, but also to limit the positioning parameters of the front suspension during the driving process of the vehicle, so that the wheels can be relatively The body has a certain space for turning and jumping, and it can be reliably connected with the subframe. Therefore, the control arm needs to have good rigidity and strength. [0003] The control arm used in the McPherson suspension of automobiles is widely used in the field of passenger vehicles due to its simple structure and small footprint. Most of the control arms of the models sold on the market with a full load of the front axl...

AI Technical Summary

Problems solved by technology

When the control arm adopts the buckle-welded structure of the upper and lower plates, there are problems of low production efficiency and unguaranteed welding effect. When casting parts are used, there are problems that the defects of the casting body are complicated and difficult to eliminate, poor in versatility, and high in development costs. Therefore, how to Improving the production efficiency of the main body of the control arm while ensuring its quality has become an urgent problem for enterprises to solve
