Problems solved by technology

However, the front subframe in this patent has an upwardly extending front vehicle body mounting frame. Compared with the front subframe directly connected with the vehicle body, this connection method reduces the rigid connection between the vehicle body and the front subframe. , at the same time, the existence of the mounting frame also aggravates the vibration problem of the front sub-frame

Abstract

The invention provides an automobile front auxiliary frame assembly. According to the automobile front auxiliary frame assembly, a front auxiliary frame upper plate and a front auxiliary frame lower plate are respectively provided with a downward lower flange and an upward upper flange, the front auxiliary frame upper plate and the front auxiliary frame lower plate form a rectangular box body structure in a surrounding mode through the up-down butt joint between the lower flange and the upper flange, two mounting grooves opposite in position are formed in the side portions of the front auxiliary frame lower plate correspondingly, front mounting frames are fixedly mounted in the mounting grooves, and stress dispersion arc surfaces are arranged between the inner side surfaces of the mountinggrooves and the front auxiliary frame lower plate. Compared with the prior art, a connection mode between the rectangular box body and the front mounting frame is changed, and the front mounting frame is wrapped in the rectangular box body in a wrapping mode, so that a connection area between the rectangular box body and the front mounting frame is expanded, the stress is dispersed, the rigiditybetween the rectangular box body and the front mounting frame and the connection firmness between the rectangular box body and a vehicle body are improved, and meanwhile the vibration of the front auxiliary frame assembly can be reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile frame, in particular to a front auxiliary frame. Background technique [0002] The subframe is the skeleton of the front and rear axles and is an integral part of the front and rear axles. The sub-frame is not a complete frame, but a bracket that supports the front and rear axles and suspension, so that the axle and suspension pass through it and then connect with the "main frame". It is customarily called "sub-frame". The sub-frame includes the front sub-frame Frame and Rear-Front Subframe, Front Subframe and Rear-Front Subframe are all important parts of a car's chassis. As an important support structure that provides installation positions for components such as stabilizer bars, steering gear, engine mounts, and swing arms, the subframe is a key force-bearing component. NVH (Noise, Vibration, Harshness) performance refers to the performance of the car in terms of noise, vibration and harsh...
