Abstract
A stepless speed variator has a planetary pump formed by symmetrically arranged gear pump with planetary structure. An oil control valve manipulated by a speed control level is used to control the oil discharged from the oil outlet of pump body. Controlling the flow and pressure oil by the oil control valve can control the rotation speed of the said planetary pump, so attaining the aim of stepless speed variation.
Description
The invention belongs to a kind of toric transmission.
At present, the kind of toric transmission is more, and application mainly is automobile and motorcycle industry.The toric transmission of using on the automobile mainly contains automatic transmission with hydraulic torque converter and steel band type toric transmission.Use at most with the rubber belt type toric transmission on the motor bike, it is identical with the steel band type toric transmission principle used on the automobile.The system that automatic transmission with hydraulic torque converter is made up of many groups planetary wheel and turbine transformer, its method for changing speed is to carry out speed change by planetary wheel, flexible buffer connection with turbine transformer overcomes the impact that gear ratio is brought, to reach infinite variable speed purpose, this speed changer structure complexity, quality is big, and volume is big, and maintenance and maintenance difficulty are big.The steel band type toric transmission is that the steel wheel by two variable-diameters connects with steel band, and cooperates turbine transformer to finish infinite variable speed overall process jointly.Though the steel band type toric transmission is simple in structure, in light weight, the diameter of steel wheel needs very accurate pressure control, this has strengthened difficulty for manufacturing technology, if it is excessive to drive quality, steel band can skid, so the steel band type toric transmission is only for using on the small-sized and mid-get car of compactness.They all need to carry out back work with turbine transformer.
Purpose of the present invention refers to providing a kind of speed change and clutch to roll into one, need not turbine transformer, and 0～1: a kind of toric transmission of stepless transformation arbitrarily between 1.
The present invention adopts gear type pump to be combined into the scheme of planet pump with the planetary structure symmetric arrangement, the gear sealing is installed in the pump housing, oil input channel is arranged on the pump housing, oil expulsion channel, and the fuel-flow control valve opening, sun wheel links to each other with input shaft, and the pump housing is connected with output shaft, also can be connected with input shaft by the pump housing, sun wheel is connected with output shaft.
The present invention is owing to adopted planetary structure, and hydrostatic drive has realized the characteristics of crankshaft drive, so simplified itself structure, has reduced volume, has alleviated weight, has improved driving efficiency.
Below in conjunction with accompanying drawing the present invention is done further argumentation.
Figure one is that figure is cutd open in the side-looking of this toric transmission.
Figure two is schematic diagrams of planet pump.
Figure two: when sun wheel is driven, when rotating with the arrow direction, hydraulic oil is inhaled into the pump housing by oil input channel 8,9, and discharge from 10,11 oil ducts, if the control cock in this moment control valve bore 1,2 are closed gradually, the discharge resistance of hydraulic oil can strengthen gradually, when the discharge resistance of hydraulic oil greatly to can make the gear rotational speed reduction time, because of the input shaft rotating speed does not become, so the pump housing is pushed and turns round; If the valve in the control valve bore is closed fully, hydraulic oil is arranged fully and is not gone out, and discharges resistance and can make gear lose the ability of relative running, the pump housing and sun wheel run-in synchronism, output shaft and input shaft run-in synchronism at this moment.This toric transmission is the impact variation utilizing the pressure of hydraulic oil to change to alleviate the input shaft rotating speed, thereby realizes infinite variable speed.
Known to sum up stating, the present invention is simple in structure, and variable speed operation is convenient, and there is not a technical difficult problem in low cost of manufacture.The in addition size of propulsive effort of the present invention and the quality of performance depend on size, modulus, the accuracy of manufacture of gear fully.
