THREE-POINT SUSPENSION ARM AND METHOD FOR MANUFACTURING THREE-POINT SUSPENSION ARM Russian patent published in 2021 - IPC B60G7/00 

FIELD: car industry.

SUBSTANCE: invention relates to a suspension of a vehicle. A three-point suspension arm for the undercarriage of the vehicle contains two load application elements, a central load application element, two median profiles and load-bearing winding. Median profiles are made of shear-rigid material. Load-bearing winding is made of fibrous polymer composite material. The arm has two brackets and a central support area. The central load application element is located in the central area. Each bracket is connected to the central support area, each has one of load application elements, which is located at the end of the corresponding bracket located opposite the central support area, each has one of median profiles, which is spatially located between the load application element and the central load application element. Load-bearing winding surrounds median profiles and the central load application element in a partial area, and it is functionally connected to median profiles, load application elements and the central load application element. Each load application element has a socket, in which the end of load-bearing winding is placed located on the side of the load application element, inserted into its corresponding socket and placed in it in such a way that it is functionally connected to the corresponding load application element. Each bracket has a groove located spatially between its median profile and its load application element. For the manufacture of the arm, the central load application element and median profiles are placed in a tool. Then, load-bearing winding is laid out and connected to the central element and the median profile. Load-bearing winding is cured and connected to load application elements. Each end of load-bearing winding located on the side of the load application element is inserted into its corresponding socket. Next, the arm is removed from the tool.

EFFECT: reduction in the weight of the arm is achieved.
