Abstract
The invention discloses an automobile variable displacement driving system. The automobile variable displacement driving system can increase or decrease the number of running single-cylinder engines capable of being stopped or started at any time according to the power needed by an automobile. The automobile variable displacement driving system comprises first, second and third single-cylinder engines capable of being stopped or started, first, second and third movable-blade impeller hydraulic pump sets, a flow direction converting valve, a differential driving integrated pump, an oil groove shell, and first, second and third hydraulic oil conveying pipelines. Each movable-blade impeller hydraulic pump set is provided with an oil inlet and is composed of large, middle and small impeller pumps with by-pass flow switching valves on the same main shaft. Power output shafts of the first, second and third single-cylinder engines capable of being stopped or started correspondingly drive the three movable-blade impeller hydraulic pump sets to run. According to the automobile variable displacement driving system, the number of the running single-cylinder engines capable of being stopped or started can be increased or decreased at any time according to the power needed by the automobile so as to drive the corresponding movable-blade impeller hydraulic pump sets to run, and power is transmitted to the differential driving integrated pump through hydraulic oil and then transmitted to wheels to drive the automobile to run. The automobile variable displacement driving system has the advantages of being reasonable in structure, low in running oil consumption, low in cost and low in carbon emission, and reducing environment pollution.
Description
Technical field
The present invention a kind ofly can add and subtract each at any time and can run and drive the Hydraulic Pump group of its correspondence by stop and start single cylinder engine according to automobile demand watt level, transmit power drive integrated pump to be transferred to the variable automobile discharge capacity drive system of wheel drive vehicle traveling again to differential by hydraulic oil.
Background technology
The vehicle that various multi-cylinder engines in the market drive, due to driving engine itself and the constructional feature of change-speed box, can not can be added and subtracted each cylinder of operation at any time and reduce oil consumption, reduce the quantity discharged of carbon dioxide according to the power of demand during automobile traveling.
We know when vehicle low speed is walked, need the power of driving engine to be very low, the power needing driving engine when going up a slope and run at high speed is very large again, and now we automobile on driving engine once operate, due to physical construction reason, all cylinders work all together, are just tickover, when when waiting traffic lights or low speed is walked, most fuel oil is wasted in heating, the multi-cylinder engine that particularly discharge capacity is large, not only oil consumption is large, and CO2 emissions are also large.
Summary of the invention
The object of the invention is invent a kind of can add and subtract at any time according to automobile demand watt level respectively can stop and start single cylinder engine run variable automobile discharge capacity drive system, be that a kind of oil consumption is low, energy-saving and emission-reduction, low-carbon (LC) run variable automobile discharge capacity drive system.
Variable automobile discharge capacity drive system of the present invention, it is characterized in that it be a kind of can add and subtract at any time according to automobile demand watt level respectively can stop and start single cylinder engine run variable automobile discharge capacity drive system, comprising first, second, third can stop and start single cylinder engine, first, second, third cover turns paddle wheel Hydraulic Pump group, change flow valves, differential with import and export drives integrated pump, oil groove housing, first, second, third hydraulic oil delivery duct; Described flow valves of changing has oil inlet, changes flow valves control stalk and two variable gangways; Described first, second, third cover turns paddle wheel Hydraulic Pump group oil inlet, often cover turns paddle wheel Hydraulic Pump group and forms by same main shaft and with the large, medium and small vane pump of by-pass flow switch valve respectively, wherein the by-pass flow switch valve of large, medium and small vane pump has oil outlet, oil inlet port, by-pass flow mouth and by-pass flow switch valve control stalk, often overlaps the large, medium and small impeller delivery side of pump turning paddle wheel Hydraulic Pump group corresponding and is communicated with the oil inlet port of corresponding by-pass flow switch valve; Described first, second, third can the power take-off shaft of stop and start single cylinder engine be corresponding respectively overlap the main shaft turning paddle wheel Hydraulic Pump group is connected with first, second, third, the corresponding drive three of Power output of stop and start single cylinder engine can overlap and turn the running of paddle wheel Hydraulic Pump group by first, second, third; First hydraulic oil delivery duct is connected to the oil outlet of whole by-pass flow switch valves, first hydraulic oil delivery duct another port is connected with the oil inlet changing flow valves, and the hydraulic oil that the by-pass flow switch valve control stalk that first, second, third cover turns paddle wheel Hydraulic Pump group can control to turn each vane pump output in paddle wheel Hydraulic Pump group enters hydraulic oil delivery duct or from the idle outflow of by-pass flow mouth by-pass flow switch valve; Two the variable gangways changing flow valves drive the import and export of integrated pump group to couple together by the second hydraulic oil delivery duct and the 3rd hydraulic oil delivery duct and differential respectively, and the hydraulic oil of backflow is back to oil groove housing from the return opening changing flow valves and goes.
Principle of work of the present invention is as follows: when vehicle needs miniwatt, start single can drive and corresponding turn paddle wheel Hydraulic Pump group by stop and start single cylinder engine, when not changing the by-pass flow switch valve turned in paddle wheel Hydraulic Pump group, hydraulic oil is back to oil groove housing from the by-pass flow mouth of by-pass flow switch valve, do not have hydraulic oil to be transported to differential and drive integrated pump group, wheel is motionless, it is neutral, when twisting by-pass flow switch valve control stalk, hydraulic oil can not flow out from by-pass flow mouth, oil outlet from by-pass flow switch valve is flowed through by the first hydraulic oil delivery duct and changes flow valves promotion differential driving integrated pump group drive vehicle wheel rotation, vehicle travels, as vehicle will go up a slope, single can the under power of stop and start single cylinder engine, can Real Time Drive idle can stop and start single cylinder engine, drive and corresponding turn paddle wheel Hydraulic Pump group, control corresponding by-pass flow switch valve control stalk, flow valves is changed because whole by-pass flow switch valve oil outlets is all communicated to by the first hydraulic oil delivery duct, so all differential all can be flowed to drive integrated pump group by the dynamic hydraulic oil of stop and start single-cylinder engine pump, transmit all can the power of stop and start single cylinder engine on wheel, because often cover turns paddle wheel Hydraulic Pump group and has greatly, in, small size vane pump composition, therefore each by-pass flow switch valve control stalk is adjusted, also the change distortion square of vehicle can be realized.
Variable automobile discharge capacity drive system of the present invention, can add and subtract at any time according to automobile demand watt level and respectively can the operation of stop and start single cylinder engine drive the paddle wheel Hydraulic Pump group that turns of its correspondence to run, transmitting power by hydraulic oil drives integrated pump to be transferred to wheel drive vehicle traveling again to differential, being superposed by actual needs respectively can stop and start single-cylinder engine mechanomotive force, plus-minus respectively can run as wheels travel provides suitable dynamic by stop and start single cylinder engine, reduces oil consumption.Have rational in infrastructure, automotive operation oil consumption is low, and cost is low, low-carbon emission, reduces the advantage of environmental pollution.
