Problems solved by technology
However, if the minimum displacement of the motor is set larger, the range of output tension of the winch hoisting mechanism will become smaller, making this hydraulic system unable to be used in occasions where the requirements for output tension vary greatly, and the application range is small

Description
technical field [0001] The invention relates to a hydraulic system, in particular to a hydraulic system which utilizes the free wheel function of a motor to increase the tension adjustment range, and is especially suitable for a winch. Background technique [0002] It is known in the machinery industry that the output tension of the winch hoisting mechanism is generally driven by a hydraulic system. [0003] At present, the hydraulic system for driving the hoisting mechanism of the winch includes a high-speed variable motor and a hydraulic device. This hydraulic system realizes the change of the output tension of the hoisting mechanism of the winch by changing the displacement of the high-speed variable motor. When the hydraulic system needs to obtain a small output pulling force, the displacement of the motor needs to be adjusted very small, and the motor speed will become very fast, which makes the reducer of the winch hoisting mechanism easy to overspeed. In order to av...
