Embodiment Construction

[0021] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0022] Hydraulic steering gear: The hydraulic steering gear is a cycloid rotary valve type fully hydraulic steering gear consisting of a servo rotary valve and a pair of cycloid rotor stators. It is a fully hydraulic steering system composed of oil supply pump, overflow valve (or diverter valve), steering cylinder and other connecting accessories. It is widely used in agricultural machinery, marine machinery, garden machinery, road maintenance machinery, forestry machinery, construction machinery and Mining machinery and other low-speed heavy-duty vehicles. Through it, the driver can realize a large steering force control with a small manipulation force, and the performance is safe and reliable, and...

Abstract

The invention provides a hydraulic system and a vehicle with the same. The hydraulic system comprises a brake release system (10), a steering system (20) and a connecting oil channel (30), wherein the brake release system (10) comprises a brake (11) and a brake release oil channel (12); the steering system (20) comprises a hydraulic steering gear (21) and a steering operation cylinder (22); the connecting oil channel (30) is connected between the steering system (20) and the brake release system (10), the first end of the connecting oil channel (30) is connected to a first oil port (211) or a second oil port (212), and the second end of the connecting oil channel (30) is connected to the oil inlet of the brake (11); either the connecting oil channel (300 or the brake release oil channel (12) is selectively communicated with the brake (11). According to the hydraulic system, the problems of high cost and low utilization rate due to the fact that an independent manual pump is required for vehicle brake release in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of hydraulic control, in particular to a hydraulic system and a vehicle including the hydraulic system. Background technique [0002] In the vehicle system, it generally includes a brake release hydraulic system that controls brake release and a steering hydraulic system that controls vehicle steering. When the brake release hydraulic system of the vehicle breaks down, the vehicle cannot be released from the brake and cannot be towed to the maintenance site smoothly, which is inconvenient for vehicle maintenance. [0003] In the prior art, in order to solve the above problems, a hydraulic system is specially provided for releasing the brake with a manual pump and realizing head correction. The hydraulic system controls the hydraulic system through the cooperation of the manual pump and the three-way valve. When correcting, the manual pump is used to distribute liquid to the steering system. When the brake needs to be...
