Description
Technical field the present invention relates to a kind of speed changer, relates to the differential planetary coupling feedback stepless speed changer that a kind of mechanical industry is carried out transmission gear shift specifically.
The present mechanical stepless transmission of background technique mainly contains three kinds of electrodynamic type, belt driven type and hydraudynamic drive formulas.Preceding dual mode is not because principle and structural restriction also obtain popularization at present.The steel-belt type stepless speed variator has a small amount of use, but makes complexity, the cost height, and the transmission energy is little, and penetration and promotion is also very difficult.At present the transmission efficiency of the automatic transmission of extensive use is low on the car, and oil consumption rises 10%, application less economical.
Summary of the invention the object of the present invention is to provide a kind of differential planetary coupling feedback stepless speed changer that addresses the above problem, this speed changer transmission efficiency height, gear range is big, velocity ratio can be realized stepless change control, simple in structure, control device is simple, and operating characteristics is reliable, adaptability is strong, and can realize Advanced Control.
The objective of the invention is to realize by following technological scheme:
A kind of differential planetary coupling feedback stepless speed changer, comprise input shaft, differential gear train and output shaft, its structure outline is: the external toothing engagement coupler output gear of said differential gear train, said coupler output gear connects the coupler output shaft, the coupler turbine is installed on this coupler output shaft, on the output shaft of said differential gear train driving gear is installed, the input gear of this driving gear engagement coupler, the input gear of coupler connects the input shaft of coupler, and the coupler pump impeller is installed on the input shaft of this coupler.When the present invention works, when the moment of torsion input is arranged on the input shaft, differential gear train drives output shaft with maximum transmission ratio and rotates, at this moment output shaft rotating speed minimum, the moment of torsion maximum, along with the input shaft rotating speed increases, the speed that output shaft rotates also increases, the pump impeller that feedback gear drives coupler rotates, and coupler pump opinion drives the turbine rotation of coupler, and the external toothing that turbine drives differential gear train rotates, thereby change the velocity ratio of differential gear train, along with the quickening of input shaft speed, thereby the velocity ratio of differential gear train is dwindled gradually, realize stepless change.
Forward gear, neutral, the control box that reverses gear are installed by input shaft place in said differential gear train front, and the transmission bevel gear is installed on the transmission axle in the control box, installation and control handle on the control gear of control transmission bevel gear.
The control ratchet that the may command external toothing rotates is installed at said external toothing place, and this control ratchet connects said Joystick.
Said coupler connects coupler liquid measure controller by hydraulic pipe line, on the said hydraulic pipe line one-way valve is installed.Can make the toggle speed of output shaft mild like this, raising speed is mild, speed ratio changes gently, external toothing speed can be controlled by the liquid measure of coupler.
Advantage of the present invention is: when the moment of torsion input is arranged on the input shaft of the present invention, differential gear train drives output shaft with maximum transmission ratio and rotates, at this moment output shaft rotating speed minimum, the moment of torsion maximum, along with the input shaft rotating speed increases, the speed that output shaft rotates also increases, the pump impeller that feedback gear drives coupler rotates, the coupler pump impeller drives the turbine rotation of coupler, the external toothing that turbine drives differential gear train rotates, thereby changes the velocity ratio of differential gear train, along with the quickening of input shaft speed, thereby the velocity ratio of differential gear train is dwindled gradually, realize stepless change.Coupler of the present invention can make that the toggle speed of output shaft is mild, raising speed is mild, speed ratio changes mild, external toothing speed can be controlled by the liquid measure of coupler, after the liquid measure of coupler is selected, the speed of output shaft and moment of torsion can obtain by the speed and the moment of torsion of control input shaft, and are stepless change; Range of transmission ratio can be formulated by the design of differential gear train, and optional scope is big; Because the characteristic of fluid coupling makes that the velocity ratio of differential gear train can be from maximum stepless change to 1, and obtains really realizing large-scale stepless change less than 1 velocity ratio by design; Because between output shaft and the input shaft is that rigidity is connected all the time, so the transmission energy is big, transmission efficiency is big, is widely used; From the control angle,, thereby make that control range is big, control accuracy is high, controlling method is easy because the liquid measure that only need control in the fluid coupling just can be controlled the stepless pace of change of velocity ratio.In sum, the principle of the invention is simple and direct, and is simple in structure, and slewing range is big, really realizes stepless change, applied range, and operating characteristics is reliable, and part is few, easily makes, and cost is low, and maintenance and repair is convenient.
