Six-point installation front auxiliary frame

Abstract

The invention belongs to the technical field of vehicle accessories, and particularly discloses a six-point installation front auxiliary frame. The six-point installation front auxiliary frame comprises a first beam frame, a left longitudinal beam, a second beam frame, an installation base and a right longitudinal beam, and the second beam frame is installed at the bottoms of the left longitudinalbeam and the right longitudinal beam in a sleeving mode. According to the six-point installation front auxiliary frame, through combination utilization of the accessories, compared with the traditional four-point installation, by changing into the six-point installation, under the situation that performance requirements are met, the weight of a chassis part can be reduced in a large interval, thecollision requirements are met, the safety of the vehicle is ensured, the assembly requirements are effectively improved, transverse spring columns are arranged in the left longitudinal beam and theright longitudinal beam, the transverse buffering performance is improved, the deformation probability is lowered, thus the bottoms of the left longitudinal beam and the right longitudinal beam are supported by a main bending frame and an auxiliary bending frame at the bottom of the second beam frame, the load buffering capacity is improved, the vibration intensity can also be lowered, and the stability of driving is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to a six-point mounted front sub-frame. Background technique [0002] Cars are driven by power and have 4 or more wheels, non-track-bearing vehicles, mainly used for: carrying people and goods; traction vehicles carrying people and goods; special purposes. [0003] The sub-frame of the car is one of the accessories of the car. The sub-frame can be regarded as 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 function of the sub-frame is to block Vibration and noise, reduce its direct entry into the compartment, so most of them appear on luxury cars and off-road vehicles, some cars are also eq...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a six-point installation front subframe to solve the current automobile industry chassis parts proposed in the above-mentioned background technology, which need to meet the collision requirements. For this reason, there are only four-point installation automobile chassis parts, and some cannot meet the crash requirements. At the same time, the subframe installed at four points needs to improve the product quality to meet the target requirements, which is not conducive to cost control and cannot reduce weight. In addition, when the longitudinal beam is a hollow structure, it lacks lateral impact resistance and is easily deformed. When the beam is fastened and connected by bolts, it is difficult to alleviate the vibration and the driving stability cannot be improved
