Hydraulic automobile transmission differential mechanism

Abstract

The invention discloses a hydraulic automobile transmission-differential mechanism, which is invented for solving large volume, complex structure and other problems of the prior art. The mechanism comprises a variable cavity type gear pump and two hydraulic motors connected with a half shaft, wherein a liquid outlet of the variable cavity type gear pump is communicated with liquid inlets of the two hydraulic motors through pipelines; liquid outlets of the two hydraulic motors are communicated with a liquid inlet of the variable cavity type gear pump through the pipelines, so as to form two driving oil lines. After the structure is adopted, by utilizing the characteristic of the variable cavity type gear pump in stepless power output, power output by an engine can drive the hydraulic motors to output power through the pipelines so as to drive an automobile to move; moreover, due to hydraulic transmission, the prior automobile differential can be realized by controlling the oil lines. The mechanism is simple in overall structure and can greatly reduce automobile-body space.

Description

technical field [0001] The invention relates to an automobile transmission and differential speed structure. Background technique [0002] In the existing automobile field, the work done by the automobile engine is sequentially transmitted to the wheels through the clutch, transmission, transmission shaft, differential, and then through the half shaft. This structure is large in size and complex in structure, which is not conducive to Miniaturization of automobiles. Among them, the differential is designed to prevent the outer wheel from slipping while rolling and the inner wheel from slipping due to the outer wheel moving a greater distance than the inner wheel when the car is turning. Yes, it is usually realized through a large number of gears, and the structure is very complicated. Contents of the invention [0003] In order to overcome the above-mentioned defects, the object of the present invention is to provide a hydraulic vehicle transmission and differential mech...
