Embodiment Construction

[0019] The accompanying drawing is an embodiment of the present invention, and the application of this embodiment is a trackless rubber-tyred vehicle suitable for underground. The front and rear frames of the car are respectively provided with a driver's cab, the driver's seat is arranged forward, and the front and rear frames are hinged at the center. This embodiment includes an oil suction filter 1, a hydraulic pump 2, a steering interlock reversing valve 3, and No. 1 steering gear 9 and No. 2 steering gear 6 respectively equipped in the two cabs. The No. 1 steering gear 9 is provided with a steering wheel. The steering device 10, the No. 2 steering gear 6 is provided with a steering device 5, and the P port of the steering interlock reversing valve 3 is connected to the oil outlet of the hydraulic pump 2. In addition, it also includes a No. 1 two-way buffer and oil supplement combined valve 8 , a No. 2 bi-directional buffer and oil supplement combined valve 4 , a No. 1 stee...

Abstract

A steering hydraulic system for a two-way driving vehicle, including a steering interlock reversing valve, a No. 1 steering gear and a No. 2 steering gear respectively equipped in two cabs, the P port of the steering interlocking reversing valve and the oil outlet of a hydraulic pump connection; there are also No. 1 and No. 2 two-way buffer oil supply combination valves and No. 1 and No. 2 steering hydraulic cylinders; the present invention is provided with two oil cylinders. When turning, one oil cylinder piston extends outward, and the other oil cylinder piston inward Contraction, the steering force is applied to the left and right sides of the hinge seat of the rear frame respectively, so the steering is sensitive and the turning radius is small. Because of the steering interlock reversing valve, when one cab is operating the steering, the steering operation 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 cross-section. In order...
