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...

Embodiment Construction

[0048] Embodiments of the present invention will be further described below.

[0049] A hydraulic transmission, including a hydraulic mechanical system, the executive element is a three-port single-ended annular oil distribution chamber screw rotor follower, wherein the annular oil distribution chamber has one port at the inlet and outlet, one port at the discharge chamber, and the output end of the oil pump is connected to the The input port of the annular oil distribution chamber of the driven machine of the screw tube rotor is connected with oil, one of the input ports of the oil pump is connected with the oil port of the output port of the annular oil distribution chamber of the driven machine of the screw tube rotor through the oil pipe with valves, and the other oil pipe is connected with the port of the discharge chamber. Close the valve, when the prime mover drives the oil pump to circulate the working medium oil, hydraulic pressure is generated in the annular oil distr...
