Abstract
The invention discloses an automotive hydraulic drive and brake integrated system through which an automobile runs by transmitting power to each wheel through hydraulic oil and the automobile is braked by preventing the hydraulic oil from flowing to generate resistance. According to the system, three variable runner impeller pumps are driven by an engine to pump the hydraulic oil to transmit power to the wheels. A double-linkage valve switch controls engagement and disengagement when the automobile starts and brake when the automobile is stopped. A valve shaft of a hydraulic oil converter valve is pressed or lifted, and the hydraulic oil flow directions of quantitative runner impeller pumps on each wheel are changed, so that an automobile power transmission control system for controlling the automobile to move forward or backwards is realized.
Description
The present invention is a kind ofly transmitted power by hydraulic oil and to each wheel, is driven running car, also is to flow and form the integrated hydraulic drive brake system that resistance comes braking vehicle to block hydraulic oil.
Its principle of work is: drive three variables commentaries on classics blade wheel pumps by driving engine and make pump hydrodynamic pressure oil; The braking when stopping to be followed in clutch during again through the starting of duplex movable valve switch Control of Automobile; As want Control of Automobile to advance or when retreating; Only need depress or mention the valve shaft that hydraulic oil changes flow valves, change the mobile direction of the hydraulic oil that quantitatively changes the blade wheel pump on each wheel and just realized.The automobile operation part that this system has been installed becomes seldom, supporting mechanical component also seldom, so energy-conservation being prone to controlled.
At present, the most driving method of automobile in the whole world is to transmit power to wheel with transmission shaft, comes transmission seldom with hydraulic efficiency pressure system, and major cause is that present hydraulic oil pump is not too energy-conservation, so the too low not widespread use that is eliminated of efficient.This energy-efficient new-type pump application in the present invention of the blade wheel pump of commentaries on classics has but been arranged, just can change the hydraulic oil driving system in auto manufacturing's market share.
The present invention has mechanical component few, controls advantages such as easy.Particularly parts of duplex movable valve switch have two kinds of functions of clutch and braking simultaneously.
Be to combine Figure of description to come principle of work of the present invention is further explained below.
Fig. 1 is a main accompanying drawing of the present invention.
Fig. 2 is the partial view that three variables change the blade wheel pump
Fig. 3 is duplex movable valve switch and the broken away view of changing flow valves
Fig. 4 is the broken away view that single variable changes the blade wheel pump
Fig. 5 be when advancing hydraulic oil duplex movable valve switch with change the flow direction figure in the flow valves
Fig. 6 be when glancing impact hydraulic oil duplex movable valve switch with change the flow direction figure in the flow valves
Fig. 7 be when falling back hydraulic oil duplex movable valve switch with change the flow direction figure in the flow valves
Fig. 8 be wheel when advancing hydraulic oil at the flow direction that quantitatively changes in the blade wheel pump
Fig. 9 be wheel when falling back hydraulic oil at the flow direction that quantitatively changes in the blade wheel pump
Among the figure, 1. the quantitative commentaries on classics blade wheel pump 2. on the wheel changes flow valves 3. duplex movable valve switches 4. variables changes the main shaft of the control separation draw runner 6. hydraulic oil storage boxes 7. of blade wheel pump group 5. variable pumps by the variable commentaries on classics blade wheel pump group of engine drives
When wanting glancing impact; The valve shaft of duplex movable valve switch to pressing down; See Fig. 6; Variable by engine drives changes the quantitative commentaries on classics blade wheel pump that the moving hydraulic oil of blade wheel pump institute pump can not supply to promote wheel again, and directly the loop is to the hydraulic oil storage box, so the power of driving engine is cut off (cutting off the control separation draw runner that power also can be mentioned whole variable pumps).And this moment, duplex movable valve switch was not allowed the obstruction of the hydraulic oil in the quantitative commentaries on classics blade wheel pump on each wheel mobile; Formation is to the braking of wheel; Otherwise during from static startup, upwards mention the valve shaft of duplex movable valve switch, engine power will be balanced and be assigned on each wheel.
In the time will falling back; The valve shaft that changes flow valves to pressing down; See Fig. 7; The moving hydraulic oil of variable commentaries on classics blade wheel pump institute's pump by engine drives is changed the flow direction after changing flow valves, also just changed the rotation direction that is communicated to the quantitative commentaries on classics blade wheel pump on each wheel, realizes the rewind function of automobile.See that Fig. 8 follows Fig. 9, we just can analyze is exactly the rotation direction that the flow direction that changed hydraulic oil changes the quantitative commentaries on classics blade wheel pump on the wheel, has realized advancing with falling back of automobile.
Transmission system in the drive system of the present invention is that 3 variables change blade wheel pump composition (also can be made up of more a plurality of pumps, see design demand).It is controlled control on the variable pump and separates draw runner and obtain the wheel torque power that needs when engine speed is constant, the electrified more easily control of draw runner is separated in the control on the variable pump, and is even better in world today's development of automobile trend.
Beneficial effect following points of the present invention:
1, good airproof performance, driving with braking is not influenced by outside environment.
2, from the driving engine to the wheel, do not have turning cylinder, by hydraulic oil pipeline transmitting power, the layout of wheel is not limited by engine location.
3, brake without friction force, brake, have the oil lubrication parts durable in use to block hydraulic oil.
4, can be directly installed on wheel on the rotor main shaft of quantitative commentaries on classics blade wheel pump formula drg, the effect of location can be arranged, let fixing more firm of wheel.
5, realize that with the separation draw runner of control variable commentaries on classics blade wheel pump speed change becomes torsion, it is easier to control, and without power-transfer clutch.
6, can divide engine power equally and arrive on each (2 to a plurality of) wheel, and parts of duplex movable valve switch have two kinds of functions of clutch and braking simultaneously, simple and reliable for structure.
Claims (4)
1. one kind transmits power by hydraulic oil and to each wheel, drives running car, also is to flow and form the integrated hydraulic drive brake system that resistance comes braking vehicle to block hydraulic oil.
2. integrated hydraulic drive brake according to claim 1 system is characterized in that: driving variable by driving engine changes the blade wheel pump and makes pump hydrodynamic pressure oil, transmission power, and the control variable changes the separation draw runner on the blade wheel pump, realizes that speed change becomes torsion.
3. integrated hydraulic drive brake according to claim 1 system is characterized in that: parts of duplex movable valve switch have two kinds of functions of clutch and braking simultaneously, and the braking when stopping to be followed in the clutch when promptly starting with duplex movable valve switch Control of Automobile.
4. integrated hydraulic drive brake according to claim 1 system; It is characterized in that: depress or mention the valve shaft that hydraulic oil changes flow valves, change the hydraulic oil that quantitatively changes the blade wheel pump on each wheel direction that flows and just realize the automobile power transmission control system that Control of Automobile is advanced or retreated.
