Fixing device suitable for high-torque transverse thrusting rod and used in vehicle

Abstract

The invention discloses a fixing device suitable for a high-torque transverse thrusting rod and used in a vehicle. The fixing device comprises bending parts, supporting boards and reinforcing boards, wherein the two bending parts are of the same structure and are symmetric left and right; each bending part comprises two board bodies arranged front and back and a connection portion; the left bending part and the right bending part are welded together through the connection portions; the width of each connection portion is H; the distance between the upper surface of each connection portion and the upper surface of the corresponding board body is D1; the distance between the lower surface of each connection portion and the lower surface of the corresponding board body is D2; each supporting board is horizontally welded between the two board bodies of the corresponding bending part; the distance between the upper surface of each supporting board and the upper surface of the board bodies of the corresponding bending part is D1; each reinforcing board is horizontally welded between the two board bodies of the corresponding bending part and located below the corresponding supporting board; and a plurality of plug welding holes penetrating through the front surfaces and the rear surfaces of the board bodies are horizontally formed in the position, above each supporting board, of the two board bodies of the corresponding bending part. The two same bending parts and the supporting board are adopted to be welded and formed, dimensions can be changed according to vehicle frame cross members of different specifications, and the machining process is simple and feasible.

Description

Technical field: [0001] The invention relates to a transverse thrust rod fixing device suitable for large moments in automobiles, which belongs to the technical field of automobiles. Background technique: [0002] At present, there are various structures of the fixing device used for the lateral thrust rod, but when the torque formed by the lateral thrust rod on the chassis frame is relatively large, the structural strength of the fixing device has more stringent requirements. The function of the lateral thrust rod fixing device is to transmit the lateral load of the automobile evenly to the chassis frame through the lateral thrust rod. The currently used lateral thrust rod fixing device cannot meet the large moment caused by the large arm. The use of the traditional lateral thrust rod fixing device can easily lead to strength damage and structural failure of the fixing device, and even lead to problems with the The serious consequences such as stress concentration and fati...
