Cargo hook gear of motor vehicle exhaustion system

Abstract

The invention relates to an exhaust system hook structure with effective constraint to the displacement of a motor vehicle exhausting system, belonging to the field of the hook structures of the exhaust system. The outer end of the hook is provided with a heading (1); the inner side of the heading is provided with a hanging component (3). A boss (2) is arranged at the central section of the hook. The hanging component is arranged between the boss and the heading, and offers effective constraint to the axial movement of the hanging component and the hook, confining the relative motion of the hanging component and the welding hook of the exhaust system within a reasonable range, and thus resolving the problem of the large-amplitude sloshing of the welding hook and the hanging component of the exhaust system when the vehicle is turning or the road condition is bad, and preventing the interference of the exhaust system and the parts around during the process of movement.

Description

technical field [0001] The invention relates to a hook structure of an exhaust system of a motor vehicle, in particular to the field of an exhaust system suspension structure for effectively restraining the displacement of the exhaust system. Background technique [0002] Most of the hooks welded on the current exhaust system use a round steel end to process an upsetting head, and then weld it on the exhaust pipe or muffler cylinder, and hang parts such as rubber hanging blocks through the upsetting head, so that the exhaust system can The parts are connected to the hooks on the side of the body. The hook structure with a single outer end heading can play the role of hanging the exhaust system, but because the suspension is relatively soft, it will be stressed for a long time or bear the weight of the exhaust system, the hole of the suspension will become larger, and the suspension will It is a gap fit with the hook; and because the welding hook on the exhaust pipe has a ce...

Problems solved by technology

The hook structure with a single outer end heading can play the role of hanging the exhaust system, but because the suspension is relatively soft, it will be stressed for a long time or bear the weight of the exhaust system, the hole of the suspension will become larger, and the suspension will It is a gap fit with the hook; and because the welding hook on the exhaust pipe has a certain axial movement margin in the design, when the vehicle makes a sharp turn or the road conditions are bad, the welding hook on the exhaust system will be in contact with the exhaust system. Axial movement of the suspension occurs. Since the suspension cannot well restrain the movement of the long straight section, the exhaust system has the risk of interference with the surrounding parts due to this movement.
