Spring fixing structure of lower control arm for rear suspension of automobile

摘要

The present invention provides a simple and easy structure in which a coil spring mounted on a lower control arm of a suspension can be easily and easily mounted to reduce the number of assembling steps to improve productivity, A spring seat is welded on the upper portion of the vehicle, or a floor height of the vehicle is lowered to increase the commerciality of the vehicle. In this case, a stress problem occurs in the coil spring, In the present invention, since the coil spring 12 is formed by forming the built-in groove 14 at a predetermined point of the lower control arm 10, there is a problem that the spring ratio is increased when designing, So that even if the floor height is low, the coil spring The coil spring can be easily designed, the ride can be improved, the coil spring can be easily mounted, and the safety and rigidity of the mounting structure can be improved. Thereby providing a spring fixing structure of the lower control arm for the rear suspension.
