Abstract

The utility model relates to a structure of an automobile sub frame, which comprises an n-shaped ring beam and a cross beam, wherein, the cross beam is welded on and connected with two feet of the ring beam and is connected with the ring beam to form a closed structure; front mounting supports which are connected with an automobile body are respectively arranged at both sides of the front side of the ring beam, and rear linings which are connected with the automobile body are arranged at both sides of the rear side of the ring beam. Strengthening supports are respectively welded at four inner corners of the closed structure formed by the ring beam and the cross beam so as to occupy an over spacious space for mounting a motor in the middle of the ring beam and enhance the rigidity of the ring beam. Furthermore, in order to enhance the Z-direction rigidity of the connection between the whole sub frame and the automobile body, strengthening parts are respectively welded on the front mounting supports and the rear linings. Through the addition of the strengthening parts on the ring beam, the cross beam and the mounting supports of the sub frame, the utility model effectively improves the rigidity and the intensity of the whole sub frame and has simple and practicable structure.

Description

A kind of automobile accessory frame structure
Technical field
The utility model relates to the car body chassis component, is specifically related to the automobile accessory frame structure.
Background technology
In the Mai Fuxun of automobile independent front suspension, most of subframes have adopted the collar tie beam structure.Horizontal and enough arrangement space are arranged in order to satisfy driving engine, the subframe collar tie beam is often all long at horizontal vertical two direction design-calculateds, and the forming process of collar tie beam generally adopts the hydraulic pressure global formation at present in the world, the inevitable like this local stiffness that reduces collar tie beam, cause the subframe resonance under some engine speed, increased internal car noise.
Summary of the invention
The utility model is at above deficiency, and a kind of simple in structure, good rigidity, automobile accessory frame that intensity is high are provided.
The technical solution of the utility model is as follows:
A kind of automobile accessory frame structure, include the collar tie beam of n type and be welded to connect with two pin of collar tie beam and be connected to become the crossbeam of an enclosed construction with collar tie beam, there is the preceding mounting bracket with body contact both sides, collar tie beam the place ahead, and there is the back bush with body contact the both sides, rear.Four corners in inboard of the enclosed construction that forms at described collar tie beam and crossbeam are welded with reinforced support, to remedy too abundant engine installation space in the middle of the collar tie beam, improve the rigidity of collar tie beam.
Further, in order to improve Z that whole subframe connects vehicle body, before described, be welded with reinforcement on mounting bracket and the back bush respectively to rigidity.
In addition, described crossbeam is made up of crossbeam upper plate and crossbeam lower plate, increases to upper overturning in crossbeam lower plate both sides, welds bushing pipe between crossbeam lower plate and crossbeam upper plate, with the Z that improves whole chassis cross-member to rigidity.
The utility model has effectively improved the rigidity and the intensity of whole subframe by increase reinforcement structure on subframe collar tie beam, crossbeam, mounting bracket, and is simple and practical.
Description of drawings
Fig. 1 is the subframe front view
Fig. 2 is the subframe back view
Fig. 3 is crossbeam upper plate, crossbeam lower plate, bushing pipe cutaway view
Among the figure, 1-collar tie beam, 2-reinforced support, 3-crossbeam upper plate, 4-crossbeam lower plate, mounting bracket before the 5-reinforcement, 6-, 7-back bush, 8-bushing pipe.
The specific embodiment
Referring to Fig. 1, the collar tie beam 1 that constitutes this subframe is the n type, two pin of crossbeam and collar tie beam 1 are welded to connect with collar tie beam and are connected to become an enclosed construction, respectively are welded with reinforced support 2 in four corners in inboard of collar tie beam 1 and the formed enclosed construction of crossbeam, to improve the rigidity of collar tie beam.There is the preceding mounting bracket 6 with body contact both sides, collar tie beam the place ahead, and there is the back bush 7 with body contact the both sides, rear, are welded with reinforcement 5 on preceding mounting bracket and back bush respectively, connect the Z of vehicle body to rigidity to improve subframe.Crossbeam is made up of crossbeam upper plate 3 and crossbeam lower plate 4, and 4 backs increase to upper overturning before the crossbeam lower plate, welding bushing pipe 8 between crossbeam lower plate 4 and crossbeam upper plate 3, with the Z that improves whole chassis cross-member to rigidity.
