Abstract

The invention provides a hydraulic system and a working vehicle, and relates to the technical field of hydraulic engineering. The hydraulic system comprises a motor group which comprises at least one driving motor and at least one working motor, a driving pump and a working pump. The driving pump is connected to the at least one driving motor; the working pump is communicated with the working motor when the hydraulic system is in the non-anti-skid mode; and when the hydraulic system is in the anti-slip mode, the working pump at least is in communication with the driving pump of the working motor and the driving motor. According to the hydraulic system provided by the invention, the anti-skid mode and the normal non-anti-skid mode can be realized. Therefore, the system can cope with different working conditions, for example, under the normal working condition, the system is switched into the non-anti-skid mode, and the power loss can be reduced. The system is switched into the anti-skid mode on an uphill and slipping road section, so that power can be increased, and the danger of car sliding or car bumping is avoided.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a hydraulic system and a working vehicle. Background technique [0002] At present, the driving hydraulic system of road rollers mostly adopts the method of single pump and double motor and double pump and double motor. The single pump and double motor can provide better traction, but the antiskid ability of single pump and double motor is limited. In working conditions, the front or rear wheels are prone to skidding, and the danger of slipping or jumping is more likely to occur when skidding occurs. Double pumps and double motors have good anti-skid ability, but the power loss is large. [0003] Therefore, how to propose a new hydraulic system and work vehicle that can provide better traction, improve the anti-skid ability of the system, and reduce power loss has become an urgent problem to be solved at present. Contents of the invention [0004] The present in...
