Front sub frame reinforcing support

Abstract

The invention discloses a front sub frame reinforcing support. The front sub frame reinforcing support comprises a reinforcing support body; reinforcing support sleeves are welded at the upper ends ofthe two sides of the reinforcing support body and are respectively a first reinforcing support sleeve and a second reinforcing support sleeve; the cross section of the reinforcing support body is ofan Omega shape; a reinforcing support left front mounting hole and a reinforcing support right front mounting hole are formed in the front end of the reinforcing support body; the reinforcing supportleft front mounting hole and the reinforcing support right front mounting hole are of Y-direction waist-shaped holes; X-direction water drain grooves are formed in the reinforcing support left front mounting hole and the reinforcing support right front mounting hole; flexible mounting cover plates are arranged at the upper ends of the reinforcing support left front mounting hole and the reinforcing support right front mounting hole and are respectively a first flexible mounting cover plate and a second flexible mounting cover plate; the lower end surfaces of the flexible mounting cover platesare high-strength plate bodies which are directly connected with a hexagon flange bolt; and the reinforcing support body, the flexible mounting cover plates and a front sub frame assembly are connected with a vehicle body longitudinal beam assembly by sharing a hexagon flange bolt.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a front sub-frame reinforcement bracket structure. Background technique [0002] The front sub-frame is the carrier of the front suspension system, carrying the front lower swing arm assembly, front steering knuckle and brake assembly, front stabilizer bar assembly, steering gear assembly and even the power system of the vehicle, blocking vibration and noise directly Entering the compartment is a vital component of the car chassis. The sub-frame and the body are generally connected by four bolts. When the vehicle accelerates or brakes suddenly, because most of the mass of the front suspension is concentrated on the sub-frame, the inertia is relatively large, so the sub-frame is very easy to produce relative to the body. movement, causing abnormal noise. [0003] A sub-frame mounting bracket (application number: 201220536345.5, announcement number: CN202863552U)...

AI Technical Summary

Problems solved by technology

[0004] The invention proposes a front sub-frame reinforcement bracket structure, which solves the complex and irregular shape of the front sub-frame installation bracket in the prior art, and the serious waste of plates; it is necessary to develop two sets of molds, which increases the cost of parts; the vehicle is prone to abnormalities Poor NVH performance and no drainage structure, the bolt installation holes are prone to water accumulation, resulting in potential safety hazards
