Abstract

The invention provides a highway-railway dual-purpose vehicle steering system which comprises a front axle hydraulic steering system loop and a rear axle hydraulic steering system loop, and the frontaxle hydraulic steering system loop comprises a first oil pump, a one-way stable diverter valve, an electromagnetic reversing valve, a steering gear, a first anti-impact valve and two first hydraulicoil cylinders; the rear axle hydraulic steering system loop comprises a second oil pump, an electric proportional reversing valve, a differential pressure sensor, a shuttle valve, a throttle plug, anoverflow valve, a second anti-impact valve and two second hydraulic oil cylinders; one first hydraulic oil cylinder is provided with a first distance sensor, one second hydraulic oil cylinder is provided with a second distance sensor, and the front axle hydraulic steering system loop and the rear axle hydraulic steering system loop share one hydraulic oil tank. Single-axle steering and double-axlesynchronous steering of the highway-railway dual-purpose vehicle can be achieved, the turning radius of the vehicle can be reduced, and the flexibility of highway and railway operation switching of the vehicle is better.

Description

technical field [0001] The invention relates to the field of road-rail vehicles, in particular to a steering system for road-rail vehicles. Background technique [0002] Railway and road dual-purpose vehicles refer to special-purpose tractors that can run on roads and rails, and are mainly used for rail traction, shunting operations and rail cargo transfer. The tractor runs at low speed and has a large traction force. It is mainly used for shunting operations and traction operations in subway depots, bullet train depots, railway station depots, metallurgical industries, power plants, chemical industries, ports, local railways, and military warehouses. It is especially suitable for warehouses. internal work. [0003] Existing dual-purpose vehicles for railway and road use traditional driving axles, driven by a single axle, and have a large turning radius, which makes it inflexible when switching between road and railway operations. Contents of the invention [0004] In or...
