Problems solved by technology
[0002] Tractors are widely used in the field of cargo transportation. Existing tractors generally use one of the full hydraulic steering system or mechanical steering system to realize the steering of the vehicle. The steering control mode is to steer by people sitting on the vehicle and manipulating the steering wheel. control, whose control mode is a single
[0003] When the tractor is transporting goods, the goods will occupy the driver's driving position, so the driver cannot take the tractor to control the steering wheel. Therefore, the existing full hydraulic steering system and mechanical steering system cannot complete the steering control. , the tractor cannot meet the needs of the existing working conditions
[0004] In summary, how to solve the problem that the existing steering control mode is single and the tractor cannot be steered outside the driving position has become a problem to be solved urgently by those skilled in the art

The invention discloses a hydraulic steering system of a tractor. The system comprises an oil tank, a gear pump, a motor, a first two-position three-way electromagnetic valve, a hydraulic steering gear, a steering cylinder and a three-position four-way electromagnetic valve; the first two-position three-way electromagnetic valve, the oil tank, the hydraulic steering gear and the steering cylinder are connected to form a manual steering system; the first two-position three-way electromagnetic valve, the oil tank, the three-position four-way electromagnetic valve and the steering cylinder are connected to form an electric steering system. According to the hydraulic steering system of the tractor, since the manual steering system is capable of controlling the tractor in the driving position, the electric steering system is capable of controlling outside the driving position, the system has two control modes, and the requirements of different conditions are met. The invention further discloses a tractor with the hydraulic steering system.
Description
technical field [0001] The invention relates to the technical field of tractors, in particular to a hydraulic steering system of a tractor. It also relates to a tractor including the hydraulic steering system. Background technique [0002] Tractors are widely used in the field of cargo transportation. Existing tractors generally use one of the full hydraulic steering system or mechanical steering system to realize the steering of the vehicle. The steering control mode is to steer by people sitting on the vehicle and manipulating the steering wheel. control, its control mode is single. [0003] When the tractor is transporting goods, the goods will occupy the driver's driving position, so the driver cannot take the tractor to control the steering wheel. Therefore, the existing full hydraulic steering system and mechanical steering system cannot complete the steering control. , the tractor cannot meet the needs of the existing working conditions. [0004] To sum up, how to ...
