Front automotive auxiliary frame

Abstract

The invention provides a front automotive auxiliary frame which comprises a front cross beam, a rear cross beam, a left longitudinal beam and a right longitudinal beam, wherein the left longitudinal beam orderly comprises a first front crumpling segment, a first transition segment and a first rear crumpling segment from front to back, and a first crumpling energy absorption rib is arranged on the first front crumpling segment; the right longitudinal beam orderly comprises a second front crumpling segment, a second transition segment and a second rear crumpling segment from front to back, and a second crumpling energy absorption rib is arranged on the second front crumpling segment; the first front crumpling segment, the second front crumpling segment and the front cross beam are on the same plane, and the first front crumpling segment and the second front crumpling segment are respectively parallel to the front end of a left front longitudinal beam of an automobile body and the front end of a right front longitudinal beam of the automobile body. According to the front automotive auxiliary frame, the left longitudinal beam and the right longitudinal beam of the automotive auxiliary frame is not easy to generate bending deformation to a passenger compartment, so that the amount of deformation of the passenger compartment can be reduced during collision, and the safety of passengers in the automobile is protected.

Description

technical field [0001] The invention belongs to the technical field of vehicle chassis, in particular to a front auxiliary frame. Background technique [0002] The front subframe is an important component of the vehicle chassis system, mainly including the main body of the front subframe, and the connection structure connected with the body, suspension and suspension parts. In addition to supporting the above parts, the front sub-frame can also block vibration and noise and reduce its direct entry into the compartment. [0003] The front sub-frame of the frame structure not only ensures sufficient rigidity and strength of the sub-frame, but also plays an important role in the collision process of the whole vehicle. In the process of automobile collision, the deformation of the passenger compartment is directly related to the injury of the occupants. The deformation of the passenger compartment should be as small as possible to ensure the living space of the occupants, and t...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to prevent the front part of the longitudinal beam of the front subframe from being crushed during the collision process of the existing front subframe, and then pull the front section of the longitudinal beam of the vehicle body to bend toward the passenger compartment, causing deformation of the passenger compartment larger amount of defects, providing a front subframe
