Abstract

The invention discloses a hydraulic travelling system of a vehicle and a cross-country aerial work vehicle, and relates to the technical field of hydraulic drive of aerial work platforms. The hydraulic travelling system of the vehicle comprises front wheels, rear wheels and first flow distributing and collecting valves, wherein the front wheels are driven by front wheel cycloid motors; the rear wheels are driven by rear wheel cycloid motors; the rear wheels are further equipped with rear wheel speed reducers for parking brake and travelling auxiliary brake. Hydraulic oil separately enters a front wheel oil path and a rear wheel oil path after being divided by the first flow distributing and collecting valves, so that the front wheels and the rear wheels are driven at the same time, and arethe same in rotation speed. The hydraulic travelling system of the vehicle provided by the invention uses the cycloid motors which are simple in structure and are low in price; only the rear wheels are equipped with rear wheel speed reducers to realize parking brake or travelling auxiliary brake, so that cost of the vehicle is greatly reduced; and power performance of the cross-country aerial work vehicle is met.

Description

technical field [0001] The invention relates to the technical field of hydraulic drive of an aerial work platform, in particular to a hydraulic traveling system of a vehicle and an off-road aerial work vehicle. Background technique [0002] At present, most of the walking systems of aerial work vehicles are driven by hydraulic pressure, and hydraulic motors are mainly divided into cycloid motors and plunger motors. The structure and principle of the orbital motor are simple, and the price is low; the structure and principle of the plunger motor are more complicated, and the cost is higher. [0003] In general, scissor-type aerial work vehicles are divided into indoor type and outdoor type, and outdoor type can be divided into ordinary outdoor type and off-road type. Indoor and outdoor scissors with better road conditions generally use cycloid motors for walking; while off-road types use plunger motors for walking. The off-road scissor aerial lift platform in the prior art ...
