Hydraulic driver and vehicle thereof

Abstract

The invention discloses a hydraulic driver with a vehicle clutch function and three vehicles thereof. An output end of an oil pump is connected with input end joint oil of an annular oil distribution cavity of a screw pipe rotor driven machine by an oil pipe; one way of an input end of the oil pump is connected with output end joint oil of the annular oil distribution cavity of the screw pipe rotor driven machine by an oil pipe with a valve, and the other way of oil pipe is connected with joint oil of a discharge cavity; when the valve is closed, a prime mover drives the oil pump; when working medium oil circularly flows, hydraulic force is generated in the annular oil distribution cavity of the driven machine to enable the working medium oil to respectively flow into a discharge cavity for circulation from each screw pipe; the hydraulic force is respectively acted on the inner walls of the rotor screw pipes to generate peripheral rotating force so as to drive the screw pipe rotor driven machine to output power; when the valve is opened, the working medium oil is circulated in a short-circuit manner by the valve to enable the screw pipe rotor driven machine to stop outputting the power; and when the valve is closed again, the screw pipe rotor driven machine immediately recovers the power outputting. The hydraulic driver serves as a clutch for large and small vehicles, and is high in fuel economic benefit and low in labor intensity of drivers.

Description

technical field [0001] The invention relates to a hydraulic mechanical system, in particular to a hydraulic transmission and its vehicle. Background technique [0002] At present, except for friction clutches, there are basically only hydraulic torque converters used in automobiles with clutch functions, which are usually composed of three components: pump wheel, turbine and fixed guide wheel. [0003] Since there is no clutch between the engine and the gearbox in an automatic transmission car, the connection between them is realized by a hydraulic torque converter. The connection between the boxes becomes non-rigid to facilitate the automatic shifting of the automatic transmission. The main advantages of the hydraulic torque converter: good automatic adaptability, improving the service life of the machine, improving the passing performance of the machine, improving the comfort of the machine, and simplifying the operation of the machine. The main disadvantages of the hydr...

Problems solved by technology

The main disadvantages of hydraulic torque converter: high cost, high quality, low transmission efficiency

The disadvantages are: the failure rate is high, the driver has to step on the clutch separation device to change gears, the labor intensity is high, and the drive shaft is generally used when the rear drive is used

However, there are no reports on the use of hydraulic transmissions as clutches in automotive applications.
