Abstract

The invention relates to a dual-way vehicle steering hydraulic system of driving automobile, comprising a steering interlocked reversing valve, a first redirector and a second redirector positioned in two cabs; wherein, the P mouth of the steering interlocked reversing valve is connected with an oil outlet of the hydraulic pump; a first and a second dual-way cushioning oil-feeding combination valve and a first and a second reversing hydraulic cylinder. The invention has the advantages that two cylinders are provided; and in changing direction, one cylinder piston is protruded out, and the other cylinder piston is retracted, which respectively exerts a steering force on the two sides of the joint chair of the back frame, so that the steering is easy to conduct, and the turning radius is small. Due to the reversing valve, when a cab is operating to change direction, the operation of changing direction of the other cab is locked.

Description

technical field [0001] The invention relates to a steering hydraulic system of a two-way driving vehicle. Background technique [0002] China Patent No. 02285016.3 utility model patent specification discloses an underground trackless auxiliary transport rubber-tyred vehicle including an engine, a transmission system, an explosion-proof system, a hydraulic system, a pneumatic system, and an electrical system. hinged. Chinese patent No. is 200620083271.9, the loader disclosed in the utility model specification specification called "four-wheel drive wheel type underground loader" includes a front body and a rear body, and the front body and the rear body are connected by a swing shaft. The above-mentioned underground vehicle is one-way running, and when operating in a trough or a belt lane with a smaller cross-section in a coal mine underground roadway, the vehicle cannot turn around, so it is not suitable for working in a smaller occasion of a roadway ...
