Automotive hydraulic transmission device

Abstract

The invention discloses an automotive hydraulic transmission device, consisting of an inductor, an electric valve, a hydraulic oil tank, a high pressure oil pump, a pole changer and a hydraulic turner. The low-pressure oil returns from an oil return pipe to the hydraulic oil tank, then enters into the inductor through the electric valve and is then transferred to the high pressure oil pump to pressurize; the output of the high pressure oil pump has two branches, one branch of high pressure oil is transferred to the hydraulic turner through the pole changer to actuate a turner to rotator, after working, the depressurized oil returns to the hydraulic oil tank through the oil return pipe; another branch of the high pressure oil enters from the bottom of the inductor, the piston is moved by utilizing the pressure to control the amount of the oil supply. The automobile hydraulic transmission device is reasonable in structure, oil-saving, easy to be operated and has a long service life.

Description

Technical field [0001] The invention relates to an improvement of an automobile transmission, which is not only applicable to various types of automobiles, but also applicable to tractors and motorcycles. technical background [0002] Automobiles are one of the most important means of transportation in modern society. With the continuous progress of society, the performance requirements of automobiles are getting higher and higher, so many related technical improvement schemes have emerged. For example, Chinese Patent No. CN00109984.1 is about "Full hydraulic vehicle hydraulic transmission and control system", which separates the high-pressure power system and the medium and low-pressure control system, and the high-pressure oil flow output by the high-pressure oil pump drives the wheels to perform forward, reverse, neutral, and speed change under the control of relevant control valves. , braking, and in-situ steering actions, the medium and low pressure oil flow output by t...

[0002] Automobiles are one of the most important means of transportation in modern society. With the continuous progress of society, the performance requirements of automobiles are getting higher and higher, so many related technical improvement schemes have emerged. For example, Chinese Patent No. CN00109984.1 is about "Full hydraulic vehicle hydraulic transmission and control system", which separates the high-pressure power system and the medium and low-pressure control system, and the high-pressure oil flow output by the high-pressure oil pump drives the wheels to perform forward, reverse, neutral, and speed change under the control of relevant control valves. , braking, and in-situ steering actions, the medium and low pressure oil flow output by the medium and low pressure oil pumps respectively drives the transmission system, the steering device, and the jacking device under the control of the corresponding control valves, and the surface and interior of the spool of the transmission control valve Axial, circumferential and radial inlet and outlet oil passages, each oil passage is connected to the motor through the movement of the spool and the specific oil passage on the casing. The structure of this device and control system is complicated, the cost is high, and the use is difficult.
