FOUR-POINT SUSPENSION ARM Russian patent published in 2021 - IPC B60G7/00 

FIELD: vehicles.

SUBSTANCE: invention relates to the suspension of the vehicle wheel. The four-point suspension arm for the suspension of the vehicle wheel contains a middle element, a thread, and four bushings. The thread is pre-impregnated with resin. The middle element has a torsion element and four load-bearing arms that are integrally connected to the torsion element. The middle element and the corresponding bushing are at least partially wrapped with thread. The corresponding bushing to accommodate the corresponding support element is located at the corresponding distal end of the corresponding support arm. The bushing has at least one rigid attachment element. There is at least one undercut between at least one rigid attachment element and the bushing. The middle element engages with the undercut to connect with the geometric closure of the bushing with the bearing arm of the middle element. For the placement and direction of the thread during the winding process, the corresponding bushing and its at least one rigid attachment element have a larger width than the corresponding bearing arm.

EFFECT: invention improves the suitability for large-scale production and accelerates the manufacturing process.
