Abstract

The invention relates to a rear suspension system capable of being disassembled rapidly, and belongs to the technical field of semitrailer production. The rear suspension system includes a suspensionlock device, a suspension walking mechanism and the like, wherein a loading platform mounted on a trailer frame is provided with the suspension walking mechanism through suspension cable devices; an air/circuit control device includes an air brake mechanism, an air storage cylinder, a one-way valve, a switch valve, an air brake inflation joint, an air brake control joint, a brake chamber, a quickrelease valve and an emergency brake valve; one pipeline/cable segment of the air/circuit control device is arranged on the skeleton of the loading platform, the other pipeline/cable segment of the air/circuit control device is installed inside the frame of the suspension walking mechanism, and the pipeline/cable segments and a socket form a connection passage through a seal plug; the suspension walking mechanism is fittingly mounted on a wedge-shaped groove of the loading platform through a locating wedge-shaped boss. The rear suspension system with the adjustable height can be flexibly assembled and disassembled, is stable and reliable during operation and is suitable for railway transportation and island-reef environments. The problems are solved that current fixed structures cannot berapidly disassembled and accordingly cannot be subjected to height adjustment and storage so that it can be difficult for the current fixed structures to adapt to the requirements for railway and island-reef transportation.

Description

technical field [0001] The invention relates to a quickly detachable rear suspension system, which belongs to the technical field of semi-trailer manufacture. Background technique [0002] The semi-trailer is a heavy-duty transportation tool suitable for both military and civilian purposes with high utilization. With the rapid development of my country's railways, in addition to passenger transport, railway transport is playing an increasingly important role in military applications. The rear suspension bearing device of the existing semi-trailer is generally welded and fixed as a whole. Because it cannot be quickly loaded and unloaded, the height of the whole vehicle cannot be adjusted. Equipped with a fixed non-detachable rear suspension load-bearing device, when military equipment needs to work for a long time, it is very troublesome to disassemble the idle fixed rear suspension load-bearing device, which is not conducive to storage, and the sun and sea wind will cause i...
