Description

Technical Field

[0001] The utility model relates to the technical field of automobile components, in particular to a rear crossbeam assembly for matching a full-hook traction hook. Background Art

[0002] With the continuous development of China's automobile industry, thanks to the high reliability and high cost-effectiveness of Chinese brand trucks, the export volume of domestic trucks has continued to rise in recent years. The demand of each country is quite different. Some application scenarios are that the whole vehicle with a cargo box is connected to a trailer through a full-hook towing hook;

[0003] In order to meet the need to install a towing hook at the rear end of the vehicle, the strength of the traditional rear crossbeam does not meet the demand. In order to increase the strength, a back-to-back or double-layer C-shaped beam structure is generally used. The outer dimensions of the full-hook towing hooks of different suppliers are different. The upper wing surface of the back-to-back beam interferes with the towing hooks of different manufacturers. According to CAE analysis and calculation, the strength of the double-layer C-shaped beam is insufficient. If a layer of reinforcement plate is added, due to the limitation of the longitudinal beam size and the superposition of three layers of beams, the arc surface occupies more space and cannot install all the components that need to be arranged, that is, there is insufficient space for the integrated installation of other components;

[0004] Therefore, based on the above problems, it is urgent to develop a rear crossbeam assembly for matching a full-hook towing hook. Utility Model Content

[0005] The purpose of the utility model is to overcome the defects of the prior art and provide a rear crossbeam assembly for matching a full-hook towing hook, thereby solving the problems of insufficient strength of the rear crossbeam in the prior art and insufficient space for integrating and installing other components.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model discloses a rear crossbeam assembly for matching a full-hook towing hook, comprising:

[0008] C-beam;

[0009] A connecting plate fixedly connected to both ends of the C-shaped beam;

[0010] A Z-shaped beam is arranged outside the C-shaped beam;

[0011] The two ends of the upper part of the Z-shaped beam are fixedly connected to the C-shaped beam and the connecting plate, the lower surface of the Z-shaped beam is coplanar with the lower surface of the C-shaped beam, and the two ends are fixedly connected to the connecting plate.

[0012] Furthermore, it also includes a reinforcing plate, and the reinforcing plate is fixedly connected to the middle part of the inner wall of the C-shaped beam.

[0013] Furthermore, the cross-sectional shape of the reinforcing plate is the same as the cross-sectional shape of the C-shaped beam.

[0014] Furthermore, the reinforcing plate is a hot-rolled metal plate and is formed by a stamping process.

[0015] Furthermore, the upper wing surface of the reinforcing plate and the C-shaped beam and the Z-shaped beam, and the lower wing surface of the reinforcing plate and the C-shaped beam are connected by bolts, and the front surface of the reinforcing plate and the C-shaped beam and the Z-shaped beam are connected by rivets.

[0016] Furthermore, the connecting plate is connected to the C-shaped beam and the Z-shaped beam through rivets.

[0017] Furthermore, the lower wing plate of the Z-shaped beam is punched with a plurality of through holes.

[0018] Furthermore, the connecting plates, C-shaped beams and Z-shaped beams are all hot-rolled metal plates and are formed by a stamping process.

[0019] In the above technical solution, the utility model provides a rear crossbeam assembly for matching a full-hook towing hook, which has the following beneficial effects compared with the prior art:

[0020] The rear crossbeam assembly effectively solves the problem of insufficient strength of the existing rear crossbeam. Not only does the combination of the C-shaped beam and the Z-shaped beam maximize the layout space and strength, but the Z-shaped beam is also punched with multiple sets of holes at the bottom, providing ample expansion space for installing other components. It has a compact structure and high strength and reliability. BRIEF DESCRIPTION OF THE DRAWINGS
