Car trailing arm car body reinforcing plate

Abstract

The invention provides a car trailing arm car body reinforcing plate capable of enhancing the strength of trailing arm mounting points and improving the reliability and safety of a trailing arm mounting structure. Side flanges are arranged on the two sides of the car trailing arm car body reinforcing plate; a front end flange and a rear end flange are arranged at the front end and the rear end of the car trailing arm car body reinforcing plate correspondingly; a first transition flange used for being welded to the inner wall of a longitudinal beam is arranged between the rear end flange and one side flange, and a second transition flange used for being welded to a threshold reinforcing plate is arranged between the rear end flange and the other side flange; and the rear end flange, the side flanges, the first transition flange and the second transition flange are connected integrally. According to the car trailing arm car body reinforcing plate, a trailing arm has more force transmitting paths during bearing, disperse transmitting of loads is facilitated, stress of metal plate areas near the mounting points and welding points can be reduced, and accordingly the trailing arm car body mounting points meet the strength performance requirements.

Description

technical field [0001] The invention relates to the technical field of automobile chassis structural parts, in particular to an automobile trailing arm body reinforcing plate. Background technique [0002] As an important part connecting the body and chassis, the trailing arm plays a key role in the coordination between the body and chassis during the running of the vehicle. When the car is on the road, it will encounter various complicated driving conditions, such as: acceleration, turning, braking and pit crossing. Under these driving conditions, the road surface will generate a large longitudinal impact load on the wheels. If the structure design of the mounting bracket of the trailing arm is unreasonable, it will often cause breakage near the mounting point of the trailing arm or the bracket itself, which may cause the vehicle to deviate Faults such as overturning even bring danger to the lives of passengers. [0003] The trailing arm is connected to the longitudinal b...

AI Technical Summary

Problems solved by technology

In fact, the quality of the internal reinforcement plate structure will directly affect the strength of the mounting point of the trailing arm body. If the structure is weak and the connection is not well considered, it may directly cause the mounting point of the trailing arm to fail to meet the strength requirements, which in turn will cause sheet metal parts near the mounting point Cracking affects the safety of vehicles
