Description

Technical Field

[0001] This utility model relates to the technical field of trailer trailers, and in particular to a torsion half-shaft support structure for trailers. Background Technology

[0002] A trailer does not have its own power system and needs to be towed by a trailer to move and reach a designated parking location. After reaching the parking location, the towing vehicle separates from the trailer. The moving mechanism is particularly important in the components of a trailer, and the trailer needs to move through tires and half-axles.

[0003] Existing torsion axle support structures for trailers, such as the trailer axle module for easy assembly and disassembly disclosed in utility model patent application number 202322076175.8, mainly include a support column and a hub unit. Mounting plates are installed on both sides of the top of the support column via connecting brackets. A telescopic column is sleeved on the inner surface of the support column, and a support plate is installed at the end of the telescopic column. A connecting column is installed on one side of the support plate, and a hub unit is installed on the outer surface of the connecting column via ball bearings. A mounting column is installed on one side of the hub unit, and a rotating shaft is installed inside the support column via bearings. A worm gear is installed on the outer surface of the rotating shaft. In use, this utility model is installed at the bottom of the trailer, and the tire is installed at the mounting column position of the hub unit. Then, according to the width of the trailer, the adjuster is rotated, which drives the worm gear to rotate. The rotation of the worm gear and worm wheel drives the rotating shaft to rotate, which in turn moves the telescopic column, thereby adjusting the position of the hub unit and the tire.

[0004] However, many torsion axles used in trailers or RVs on the market currently suffer from tire wear. The root cause of this problem is that the axle camber angle is too large, causing the tires to form a "V" shape. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a torsion half-shaft support structure for trailers, which can effectively solve the problem of excessive tilt angle of the torsion axle assembly by setting a support half-shaft ring, and prevent the tire wear caused by excessive tilt angle after the axle tires are installed.

[0006] This utility model discloses a torsion half-shaft support structure for trailers, including an axle tube assembly; it also includes a torsion half-shaft, a round bar, and two sets of half-shaft support rings. The torsion half-shaft is installed inside the axle tube assembly, the round bar is installed on the torsion half-shaft, and the two sets of half-shaft support rings are all fitted on the torsion half-shaft to support the torsion half-shaft and prevent the round bar from moving axially. When the axle tube assembly is under load, the two sets of half-shaft support rings will support both ends of the torsion half-shaft, ensuring that the torsion half-shaft always remains in a horizontal position and that the angle between the axle head and the horizontal plane does not become too large as the load on the axle tube assembly increases.

[0007] Preferably, the round bar is made of rubber, which is wear-resistant and can extend the service life of the device.

[0008] Preferably, it also includes a half-shaft support ring, which has an outer square and inner circle structure; the outer square and inner circle structure is easier to install and disassemble, making it convenient for workers to assemble and disassemble.

[0009] Preferably, it also includes a half-shaft support ring, which is a circular ring structure; the circular ring structure is easy to process, facilitates mass production, and saves production costs.

[0010] Preferably, it also includes a shaft retaining ring, which is installed on the torque half-shaft; by setting the shaft retaining ring, the axial movement of the half-shaft support ring can be prevented.

[0011] Preferably, the shaft retaining ring is selected as an elastic retaining ring; in addition to having the basic functions of a shaft retaining ring, the elastic retaining ring can also alleviate shaft vibration and vibration to a certain extent, and improve the working stability and service life of mechanical parts.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: when the bridge tube assembly is under load, the two sets of half-shaft support rings will support both ends of the torque half-shaft, ensuring that the torque half-shaft always remains in a horizontal position, and the angle between the shaft head and the horizontal plane will not be too large as the load on the bridge tube assembly increases.
