Lower arm support bush in front suspension

摘要

The present invention relates to a bush, and more particularly, to a bush for supporting the lower arm of the front suspension (abbreviated as G-point bush for convenience according to the layout of the bush).;According to the present invention, a torsion spring is embedded in the bush housing, the torsion spring is coupled to one side of the bush housing by a bolt, and a separate leaf spring member is coupled to the other surface of the bush housing by bolts, The leaf spring is coupled by a bolt to the curved portion of the torsion spring, the leaf spring being provided with a lower arm support bush of the front suspension to be welded to the curved portion of the torsion spring; The supporting bush has a river bush attached to a portion of the inner surface of the torsion spring to prevent the adjacent winding parts of the torsion spring from colliding with each other when the arm shaft is displaced laterally, and the rubber bush is torsion in a curved shape. It is characterized in that attached to the inner surface of the spring.;According to the above configuration, when the lateral displacement of the arm shaft becomes large, the rubber bush absorbs the impact force of the arm shaft in addition to the torsion spring, thereby ensuring the reliable operation of the torsion spring and improving the riding comfort.
