Description

A detachable arch beam

technical field

The utility model relates to a detachable arched beam, in particular to an arched beam structure for heavy vehicles, belonging to the field of arched beams.

Background technique

At present, due to the large length of the engine gearbox assembly of heavy-duty tractors, in order to facilitate the assembly of the engine gearbox assembly, the spans of the first beam and the second beam of the frame are relatively large. After the assembly is completed, the second beam is generally located above the gearbox. If the engine is positioned higher, the second beam will adopt an arched structure to prevent interference with the gearbox. If the operating conditions of the vehicle are bad, the frame often twists, and the span between the first beam and the second beam is too large, which will affect the strength of the entire frame.

Utility model content

Aiming at the above problems, the utility model provides a detachable arched beam, which is the second beam of the vehicle frame. The utility model can shorten the distance between the first beam and the second beam, and improve the overall Strength without affecting the assembly of the engine gearbox assembly. The technical scheme of the utility model is as follows:

A detachable arched beam, comprising a left bracket assembly, an upper beam, and a right bracket assembly, the two ends of the upper beam are respectively connected with the left bracket assembly and the right bracket assembly, and the two ends of the upper beam The sides are respectively provided with threaded holes A, and the side of the middle bend is provided with two groups of through holes, which can be used to fix the wiring harness. The left and right bracket assemblies include a bottom plate and a U-shaped bracket respectively. The U-shaped bracket is fixedly connected, and the connection between the base plate and the U-shaped bracket is provided with reinforcing ribs. The base plate is provided with mounting holes for installing the utility model on the frame longitudinal beam. The U-shaped bracket is provided with There are threaded holes B corresponding to the threaded holes A at both ends of the upper beam, which are used to fix the left and right bracket assemblies to the upper beam.

On the basis of the above technical solution, there are four installation holes on the bottom plate.

On the basis of the above technical solution, three threaded holes A are respectively provided on the two ends of the upper beam.

On the basis of the above technical solution, there are two groups of through holes at the middle bend of the upper beam, and each group has two through holes.

On the basis of the above technical solution, the structure of the upper beam is an inverted U shape.

On the basis of the above technical solution, the left and right bracket assemblies are connected to the upper beam through bolts.

On the basis of the above technical solution, the fixing method of the bottom plate and the U-shaped bracket is welding.

The arch beam assembly is fixed on the frame longitudinal beam through the left and right brackets. When assembling the engine gearbox assembly, remove the upper beam, so that it will not be affected by the shortened distance between the first beam and the second beam. Assembly of engine gearbox assembly.

The utility model has the following advantages:

The utility model has simple structure, is convenient and practical, is beneficial to the assembly of the engine gearbox assembly, can prevent the second beam from interfering with the gearbox, and effectively avoids frequent torsion of the vehicle frame.
