Abstract

The invention belongs to the technical field of suspension, and discloses a secondary limit device for suspension, comprising: an integrated support, a movable limit block and an elastic buffer block; the integrated support is provided with an oil-gas spring fixing part and a limit The fixed part, the movable limit block is detachably fixed on the limit fixed part; the elastic buffer block is fixed on the movable limit block. The device provided by the invention can adapt to special scenarios of special vehicles, lowering the suspension to realize rigid support of the vehicle body, and realizing elastic limit and reducing impact damage of parts in conventional scenarios.

Description

technical field [0001] The invention relates to the technical field of suspensions, in particular to a suspension secondary limiting device, a suspension limiting structure and an oil-gas suspension. Background technique [0002] The suspension device of the heavy-duty special off-road vehicle is provided with a limiter, including an upper limit and a lower limit. The lower limit limits the range of the wheel's downward jump, and the upper limit limits the range of the wheel's upward jump. When the vehicle is running, the wheel always jumps within the limit range, which can prevent problems such as structural interference caused by excessive wheel jumping range. With the railway transportation, passability and other specific functional requirements of heavy-duty special off-road vehicles, the suspension system of heavy-duty special off-road vehicles requires a height adjustable function, which is generally realized by a hydraulic system. However, there is a technical proble...
