Abstract

The invention discloses a hydraulic system for controlling a vehicle to realize two-way travelling, belongs to the technical field of engineering vehicles, overcomes the shortages in the prior art, and provides the hydraulic system for controlling the vehicle to realize the two-way travelling which is low in manufacturing cost and can control the vehicle to realize the two-way travelling. In order solve the technical problem, the technical scheme adopted by the invention is that the hydraulic system comprises a steering device, an oil pump, an oil box and a hydraulic oil cylinder, wherein a steering wheel arranged on the steering device controls the steering device to act; the oil pump and the oil box are respectively communicated with an opening P and an opening O in the steering device through corresponding oil pipes; an opening A and an opening B of the steering device are correspondingly communicated with an opening P1 and an opening P2 of the hydraulic oil cylinder through a hydraulic manifold block; the opening P1 and the opening P2 are respectively positioned on the two sides of a piston of the hydraulic oil cylinder; and a piston rod of the hydraulic oil cylinder is connected with a steering mechanism of the vehicle. The hydraulic system is mainly used on an engineering vehicle in a laneway.

Description

technical field [0001] The invention relates to a hydraulic system for controlling a vehicle to realize two-way driving, which belongs to the technical field of engineering vehicles. Background technique [0002] At present, in the production of large and medium-sized coal mines in my country, various operations under the mine are restricted by the roadway, which makes the transportation of vehicles in the roadway underground and the repair, maintenance, installation, and movement of a large number of coal mining equipment underground become coal production enterprises. an outstanding problem. [0003] Similar products on the market are roughly divided into two categories. The first category of two-way driving mechanism usually uses a gearbox to achieve front and rear steering, and the structure is complex. Before manufacturing, casting molds, parts blanks, fixtures and processing accessories need to be invested. high cost. [0004] The other is the use of hydraulic torque ...
