A curved boom part used for an automobile chassis in a matched mode comprises an arc-shaped curved boom body; the two ends of the arc-shaped curved boom body are provided with outer convex end connectors respectively; a sheet-shaped curved structure with the width of the middle arc-shaped curved portion being greater than the widths of the two ends is formed; one of the outer convex end connectors is provided with an axial connection through hole and a pin hole communicated with the axial connection through hole in the radial direction; the other outer convex end connectors is provided with an integrally-formed connection screw; the outer convex position of the middle arc-shaped curved portion of the arc-shaped curved boom body is provided with an integrally-formed outer convex middle connection connector and an axial connection hole, and a hinge pin hole communicated with the axial connection hole is formed in the radial direction; the axis of the axial connection through hole is parallel to the axis of the axial connection hole; the axis of the axial connection through hole and the axis of the connection screw form an included angle ranging 10 degrees to 12 degrees. The curved boom part has the characteristics of being simple and reasonable in structure, practical, convenient to use, reliable, convenient to machine, high in strength and toughness and the like.
Description
technical field [0001] The invention relates to a curved arm part matched with an automobile chassis, and belongs to the technical field of connecting parts for automobile chassis parts. Background technique [0002] In the prior art, the function of the chassis of the automobile is to support and install the automobile engine and its components and assemblies. It receives the power of the automobile engine and transmits the power to make the automobile move, ensuring the normal running of the automobile. The curved arm part, as a safety part with load-bearing and guiding functions, has to bear complex torque transmission and alternating stress in practical applications. Therefore, the strength and toughness of the curved arm part have high requirements, which involves To the rationality of the overall structure of the bent arm; the currently used bent arm structure has unreasonable structure, strength, toughness and processing convenience.
