Abstract

The invention discloses an arc-shaped beam connected with the bottom of a vehicle frame. The arc-shaped beam comprises a middle part and connecting parts, wherein the middle part and the connecting parts are of an integrated structure; the connecting parts are located at the left and right ends of the middle part, the end face of the middle part is in a circular shape, the end faces of the connecting parts are each in an oblate shape, plugs are arranged in the connecting parts, and connecting holes penetrating through the plugs are formed in the outer surfaces of the connecting parts. The arc-shaped beam is low in weight, simple in technology, high in connecting stiffness and wide in application range.

Description

technical field [0001] The invention relates to an arc-shaped beam connecting the bottom of the vehicle frame, which is particularly suitable for the connection of the vehicle frame. Background technique [0002] In automobile design, in order to increase the rigidity of the frame, in addition to connecting the left and right longitudinal beams on the frame with crossbeams, the rigidity of the connection must be further increased by adding arc-shaped beams connecting the bottom of the frame. However, most of the existing arc-shaped beams connecting the bottom of the frame are sheet metal stamping parts or castings, so the weight is heavy, the process is complicated, and the connection rigidity is not high, and it can only be used for single front axle vehicles, and the scope of application is not wide. wide. Contents of the invention [0003] The object of the present invention is to overcome the defects and problems of heavy weight and complicated process in the prior ar...
