Adjustable cargo trailer shock absorption and supporting structure

Abstract

The invention discloses an adjustable load trailer shock-absorbing support structure, which is used to support the trailer plate by a beam structure and a center beam structure; Trailer wheels; the inner ends of the front and rear trailer wheels adjust the main support arms to maintain a rotatable and flexible connection with the adjustment bearing support; the invention controls the telescopic movement of the front wheel adjustment cylinder and the rear wheel adjustment cylinder to control the front wheel. The trailer wheel adjustment main support arm and the rear trailer wheel adjustment main support arm rotate on the adjustment bearing support to adjust the distance between the front trailer wheel and the rear trailer wheel, and can also adjust the height between the trailer plate and the ground; At the same time, since the inner ends of the front and rear trailer wheel adjustment main support arms respectively maintain a rotatable and flexible connection with the adjustment load-carrying support, the shock absorption performance of the present invention is enhanced compared with the existing trailer support structure, and no additional shock absorber is required. shock system.

Description

technical field [0001] The invention relates to a support structure for a trailer, in particular to an adjustable shock-absorbing support structure for a loaded trailer. Background technique [0002] At present, flatbed trailers are widely used, and common trailers can be used to carry luggage and goods of passengers in airports and stations. However, the structure of the existing trailer itself is usually formed by welding steel frames, which is complex in structure, difficult to manufacture, and high in manufacturing cost. In order to enhance the comfort of transportation, the trailer is usually also provided with a shock absorbing mechanism. [0003] After searching, it is found that the utility model of patent No. CN201320007375.1 discloses a trailer damping device, including: a supporting part, a protruding top column is arranged on the supporting part; a damping spring, and one end of the damping spring is sleeved on the protruding On the top column; shock-absorbing ...

AI Technical Summary

Problems solved by technology

[0006] However, after analysis, it is found that the existing trailers are equipped with independent shock-absorbing supports, and the shock-absorbing support structures are rigidly connected. When the flatbed trailer passes through uneven roads, it is easy to cause damage to the rear axle, which greatly shortens the life of the flatbed trailer. The service life of the trailer; secondly, the existing shock absorption system can only realize the shock absorption function, and cannot play an overall auxiliary support for the trailer
