Abstract

The utility model relates to an automobile rear torsion beam device. It includes a rear torsion beam (1) and a rear stabilizer bar (2) on it, the end of the rear torsion beam (1) is connected to a brake disc (3), and it is characterized in that the rear torsion beam (1) passes through The connecting block (4) is connected to the brake disc (3). The torsion beam device is connected to the brake disc through the connecting block. If it is found that the rear wheel track, rear wheel camber and rear wheel toe-in do not meet the design requirements during loading, the external dimensions of the connecting block can be redesigned. To meet the design requirements, because the connection block has a simple structure and a small volume, the development time is shortened and the development cost is also reduced.

Description

Automotive rear torsion beam device

technical field

The utility model relates to an automobile component, in particular to an automobile rear torsion beam device.

Background technique

With the development of the economy and the improvement of people's living standards, the automobile has become one of the important means of transportation for people to travel, and the parts on the automobile are indispensable components of the automobile. The rear torsion beam device on the car is one of the essential parts of the car. The traditional car rear torsion beam device is like this. The brake disc is directly connected to the upper transverse end of the rear torsion beam on the rear torsion beam. With such a connection method, if it is found that the rear wheel track, rear wheel camber and rear wheel toe-in do not meet the design requirements when loading the vehicle, the rear torsion beam must be redesigned and re-opened to meet the requirements. Thereby increasing the development cost, but also prolonging the development time.

As mentioned above, the prior art has the following deficiencies: if it is found that the rear wheel track, rear wheel camber and rear wheel toe-in do not meet the design requirements when loading the vehicle, the rear torsion beam must be redesigned and redesigned. To meet the requirements, the development cost is high and the development time is long.

Contents of the invention

The utility model solves the problems in the prior art that the rear torsion beam does not meet the design requirements, which requires high redevelopment cost and long development time, and provides an automobile rear torsion beam device without redesigning the rear torsion beam.

The above-mentioned technical purpose of the utility model is mainly solved by the following technical solutions: a rear torsion beam device for automobiles, including a rear torsion beam and a rear stabilizer bar on it, the end of the rear torsion beam is connected with a brake disc, and its characteristic The reason is that the rear torsion beam is connected to the brake disc through the connecting block. A connection block is added between the rear torsion beam and the brake disc, so that when problems such as rear wheel track, rear wheel camber and rear wheel toe-in are found that do not meet the design requirements during loading, It is only possible to redesign the external dimensions of the connection block between the rear torsion beam and the brake disc, and only re-open the mold for the connection block. Because the connection block is simple in structure and small in size, it can be used for the designer's redesign and the manufacturer's Re-opening the mold reduces many unnecessary troubles, thereby shortening the development time and reducing the development cost.

Preferably, the connecting block is in the shape of a trough, and the two sides of the trough are connected to the rear torsion beam in an L-shape, and the bottom of the trough-shaped connecting block is connected to the brake disc. The connecting block is arranged at the lateral outer end of the rear torsion beam, and the groove-shaped two sides of the connecting block are hypotenuses. A right-angled side of the groove-shaped side of the connection block is adjacent to the hypotenuse, and then the hypotenuse is adjacent to the side of the L row. The right-angled side is adapted to the shape of the brake disc and plays a role in supporting the brake disc.

The utility model is ingeniously conceived, and the rear torsion beam and the brake disc are connected through a connecting block, so that compared with the prior art, it has the following beneficial effects:

When problems such as rear wheel track, rear wheel camber and rear toe-in are found that do not meet the design requirements during vehicle loading, only the external dimensions of the connecting block between the rear torsion beam and the brake disc can be redesigned. And only the connecting block is re-molded. Because the connecting block has a simple structure and small size, it saves a lot of unnecessary trouble for the designer's redesign and the manufacturer's re-molding, thereby shortening the development time and reducing the development cost.

Detailed ways

The technical solutions of the present utility model will be further described below through the embodiments and in conjunction with the accompanying drawings.

Example 1. See Fig. 1 and Fig. 2, a kind of automobile rear torsion beam device of this example, comprise rear torsion beam 1 and rear stabilizer bar 2 on it, this rear torsion beam 1 end is connected with brake disc 3, described rear torsion force The beam 1 is connected to the brake disc 3 via a connecting block 4 . The connecting block 4 is groove-shaped, and the torsion beam 1 is L-shaped after the two sides of the groove are connected, and the groove bottom of the groove-shaped connecting block 4 is connected to the brake disc 3 . The overall shape of the connection block 4 is adapted to the shape of the connection between the brake disc 3 and the rear torsion beam 1 .

Wherein, the connecting block 4 is arranged at the lateral outer end of the rear torsion beam 1, and the groove-shaped sides of the connecting block 4 are hypotenuses. A right-angled side of the groove-shaped side of the connection block is adjacent to the hypotenuse, and then the hypotenuse is adjacent to the side of the L row (as shown in Figure 1), and the right-angled side is adapted to the shape of the brake disc to play a role Supports brake disc action.

It is obvious to those skilled in the art that the present utility model can be changed in many ways, and such changes are not considered to depart from the scope of the present utility model. All such modifications obvious to those skilled in the art are intended to be included within the scope of this claim.
