An anti-rolling mechanism for an independent suspension system of a self-loading and unloading cargo semi-trailer

Abstract

The invention discloses a side tilting prevention mechanism of an independent suspension system of a self-goods-loading / unloading semitrailer. The mechanism comprises an oil cylinder slide pin, a first lubrication washer, a locking screw, a second lubrication washer and a chute. The oil cylinder slide pin is arranged at a connected end of a suspension oil cylinder and a suspension structure of the independent suspension system; the chute is formed between the oil cylinder slide pin and a frame structure; and the oil cylinder slide pin is clamped in the chute, and is formed to a slide pair with the chute. When the suspension system jolts due to the difference of road conditions, the longitudinal force of the suspension structure can be transferred to the frame structure through the suspension oil cylinder, and the transverse force of the suspension structure can be transferred to the frame through the oil cylinder slide pin and the chute, so that the transverse stability of the whole vehicle in the driving process can be improved, and the effect of preventing the transverse unstability of the suspension oil cylinder is achieved.

Description

technical field [0001] The invention relates to an anti-rolling mechanism of an independent suspension system of a self-loading and unloading cargo semi-trailer, which belongs to the field of automobiles. Background technique [0002] At present, the suspension system of traction semi-trailer can be divided into oil-pneumatic suspension, air suspension and leaf spring suspension according to different shock absorption forms, and most of them adopt non-independent suspension structure. However, for the independent suspension system of tractor-type semi-trailer, whether it adopts oil-pneumatic suspension or air suspension, there will be a danger of rolling, especially in the condition of lifting and turning with a full load, which will cause the shock absorber to move laterally. Instability, in severe cases, the oil cylinder cannot be retracted in place, and the vehicle cannot be used normally due to severe unbalanced load. Contents of the invention [0003] In order to sol...
