Abstract
The utility model provides a torsion beam of an automobile rear axle, belonging to the technical field of automobiles. The torsion beam mainly solves the problems that the operation stability of the whole automobile is affected as the bearing capability of an existing main beam structure is poor. The torsion beam of the automobile rear axle comprises a main beam and trailing arms connected to the two ends of the main beam respectively, and a spring tray is fixedly connected at the connection position of the trialing arms and the end part of the main beam, the main beam is a strip-shaped body, and the middle part of the strip-shaped body is provided with an arc-shaped bulge, the strip-shaped body is provided with a U-shaped cross section, the spring tray is positioned at one reversed side of a U-shaped opening. According to the torsion beam, the shearing central height is increased due to the bulge of the main beam, a whole rear hanger frame follows the understeering trend, and the handling of the whole automobile is improved.

Summary of the invention
The purpose of the utility model is to existing deficiency, provides a kind of and makes torsion beam have the torsion beam of the automobile axle of big load-carrying capacity through the version that changes torsion beam.
The purpose of the utility model can realize through following technical proposal: a kind of torsion beam of automobile axle; Comprise girder and the trailing arm that is connected to the girder two ends; The junction of this trailing arm and girder end is fixed with spring tray; Described girder is the strip shape body that a middle part has an arc convex, and this strip shape body has the cross section of U-shaped, and above-mentioned spring tray is positioned at a reverse side of U-shaped opening.
The torsion beam of this automobile axle mainly is made up of girder and trailing arm; This girder is fixed on the vehicle body; The middle part of girder has the convexity of the arc that makes progress; Trailing arm is connected in the girder two ends, and the main bearing vehicle body of girder bearing capacity up and down can improve the load-carrying capacity of girder through the sinuousness that changes the girder above-below direction.
In the torsion beam of above-mentioned automobile axle, the height of said girder arc convex is 60mm～100mm.The protruding shear center height that improves of girder makes whole rear suspension trend understeering trend, and it is handling to improve car load.
In the torsion beam of above-mentioned automobile axle, the height of said girder arc convex is 80mm.The purpose that is provided with like this is to make things convenient for the arranging exhaust air pipe, and freeing pipe is passed at the girder high spot, improves the car load ground Clearance.
In the torsion beam of above-mentioned automobile axle, the U-shaped opening direction of said girder is that level is before car.The purpose that is provided with like this is that spring tray is contacted with the U-shaped bottom of girder fully.
In the torsion beam of above-mentioned automobile axle, be provided with stabilizer rod in the U-shaped opening of said girder, these stabilizer rod two ends are connected on the trailing arm respectively.This stabilizer rod is that the structural strength of girder is done important replenishing, and improves the overall mechanical strength of girder.
In the torsion beam of above-mentioned automobile axle, described trailing arm is the round tube arm.
Compared with prior art, the middle part of the girder in the torsion beam of this automobile axle has the strip shape body of an arc convex, and this strip shape body has the cross section of U-shaped; Has bigger load-carrying capacity; Improve the intensity of back axle, can improve the operation stabilization performance of car load, thereby satisfied the ride comfort requirement of car load; The girder convexity also improves the shear center height, makes whole rear suspension trend understeering trend, and it is handling to improve car load; Also make things convenient for the arranging exhaust air pipe, freeing pipe is passed at the girder high spot, improve the car load ground Clearance.
