Abstract

The invention provides a four-wheel steering control system, a four-wheel vehicle and a tractor, belonging to the vehicle field. The four-wheel steering control system comprises a hydraulic tank, a hydraulic pump, a steering gear, a front-axle steering cylinder, a reversing valve and a rear-axle steering cylinder, the hydraulic pump is connected with the hydraulic tank and passes pressurized oil into the steering gear through an oil pipe, and the steering gear passes pressurized oil into the front-axle steering cylinder and the rear-axle steering cylinder. The front axle steering cylinder andthe rear axle steering cylinder are respectively connected with the front bogie and the rear bogie of the four-wheel vehicle, and the piston rod of the oil cylinder drives the bogie to rotate to realize steering. By switching the working position of the steering gear and the reversing valve, the front wheel and the rear wheel can be steered at the same time, so that the turning radius of the four-wheeled vehicle and the tractor can be reduced; And easy to steer and manipulate.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a four-wheel steering control system, a four-wheel vehicle and a four-wheel tractor. Background technique [0002] The steering of the four-wheel vehicle is usually two-wheel steering, and the turning radius of the two-wheel steering is relatively large; it is inconvenient to turn in hilly areas. When the tractor is working in the farmland, its turning radius is required to be small to ensure the normal operation of the tractor. Contents of the invention [0003] The object of the present invention is to provide a four-wheel steering control system capable of controlling four-wheel steering simultaneously. [0004] Another object of the present invention is to provide a four-wheel vehicle, which adopts the above-mentioned four-wheel steering control system. [0005] Another object of the present invention is to provide a tractor which adopts the above-mentioned four-wheel steering con...
