Description

Lifting bracket to lift the shaft

technical field

The utility model relates to the field of heavy truck airbag lifting, in particular to a lifting bracket that can lift the shaft.

Background technique

Improving fuel economy has always been a topic in the heavy truck industry. And with the improvement of living standards, comfort has gradually become a concern. Relying on the airbag to lift the whole vehicle, on the one hand, the rear axle can be lifted when it is unloaded, which can greatly improve fuel economy, and at the same time, the air suspension can improve driving comfort. Heavy trucks with air suspension that rely on airbags to lift have also developed rapidly in recent years. However, most of the airbag lifting devices on trucks currently use a lifting method in which two airbags are respectively placed on both sides of the bridge, and the structure is complicated.

In order to solve the above problems, it is necessary to design a new type of lifting bracket.

Contents of the invention

In order to solve the problem of the complex structure of the current airbag lifting method, the utility model provides a lifting bracket capable of lifting a shaft.

The utility model is realized through the following technical solutions: the lifting bracket for lifting the shaft includes a bracket with a right-angled inverted U-shaped structure composed of left and right side plates and an upper end plate connecting the two side plates, which are formed by bending steel plates. The flange turned up 90° upwards from the front side of the upper end plate (the direction of the front side shown in Figure 2), is welded to the rear side of the upper end plate of the upper end plate and has a triangularly bent reinforcing rib in the middle,

The convex surface of the triangular bend of the reinforcing rib faces forward, and the upper end plate is provided with an upper screw hole connected with the airbag. The straight line and the horizontal plane have the same acute angle structure, the rear sides of the two side plates have the same arc structure, the side screw holes for fixing the brake pipeline are opened on both side plates, and the lower ends of the two side plates are opened with support Notch for shaft weld support fit.

During specific use, the steel plate of the support adopts a 10mm thick Q345B steel plate, which is light in weight and can fully meet the use requirements.

The lifting bracket of the lifting shaft described in the utility model is formed by bending steel plates, and the built-in flanging and welded reinforcing ribs can effectively improve the strength, and the gaps at the lower ends of the two side plates are welded to the supporting shaft It can be used as a lifting shaft to realize the lifting function. It is easy to process and does not need to open a special mold; and while meeting the strength requirements, no excessive ribs are used, which is beautiful and light in weight; in addition, the triangular bending structure on the ribs can Avoiding the airbag joint does not affect the normal use of the airbag, and can also play a role of strengthening support in the longitudinal direction.

Detailed ways

The lifting bracket that can lift the shaft includes a bracket that is formed by bending steel plates and is formed by bending the left and right side plates 1 and the upper end plate 2 connecting the two side plates 1. The turned-up flange 3 is welded to the rear side of the upper end surface of the upper end plate 2 and the reinforcing rib 4 bent in a triangular shape in the middle,

The convex surface of the triangular bending of the reinforcing rib 4 is facing forward, and the upper end plate 2 is provided with an upper screw hole 5 connected with the air bag, and the straight line and the horizontal plane at the front side of the two side plates 1 all have the same acute angle structure. The rear sides of the side plates 1 are all of the same arc structure, and the side plates 1 are provided with side screw holes 6 for fixing the brake pipeline, and the lower ends of the side plates 1 are provided with gaps 7 for welding and supporting the supporting shaft.

During specific implementation, the angle of the acute angle is 40°, and the arc structure is an arc of R500mm. This structure can keep the installation surface of the upper end plate 2 away from the support shaft, and at the same time strengthen the strength of the bracket itself.
