Description
Technical field
The present invention relates to a kind of automotive transmission, especially relate to a kind of hand from dual-purpose speed changer.
Background technique
Automatic transmission mainly contains two kinds at present, one is automatic mechanical transmission AMT, it has realized automatic manipulation by clutch separation and the selector fork etc. of manual transmission by the parts of human control taking manual transmission as parent, realizes by electronic or hydraulic power.It is the same that pilot control gets up with automatic transmission, has so just realized the automation of manual transmission, i.e. automobile electric/hydraulic control automatic mechanical transmission; Another kind is stepless speed variator CVT, it is realized by planetary pinion, there is essential difference with manual transmission, its advantage is that its gear ratio is not the point being interrupted, but a series of continuous values, thereby realized good Economy, power character and driving smoothness, and reduced discharge and cost, but its manufacture cost is more much higher than AMT.Also have a kind of hand from dual-purpose speed changer, comprise a manual transmission and an automatic transmission, and switch between two speed changers by a COMM communication, realize hand from dual-purpose object.
The advantage of AMT is mainly: 1, retain original manual transmission structure constant, transmission efficiency is high; 2 original manufacturing mechanism major parts are general; 3 by Intelligent electric and control, significantly reduces oil consumption and wearing and tearing.Automated mechanical formula manual transmission replaces original manual control device by gear shift and Bian He device actuator, is controlled by TCU and carries out gear shift.And in TCU, establish gear shift control program, and according to the signal deciding such as the speed of a motor vehicle, accelerator pedal gearbox working state, optimize motor in running process simultaneously, become the running parameter that closes the each parts of power system such as device, reduce oil consumption, reduce mechanism wear.
Current automatic mechanical transmission is mainly undertaken by the staggered driving of hydraulic system or two motors.The Chinese patent that for example publication number is CN101307829 discloses a kind of automatic mechanical type manual speed-changer gearshift, comprise: three identical cover cylinder gearshifts, a proportional pressure control valve, six identical solenoid valves, a system oil inlet pipe and a system are migrated and managed, wherein: each cover cylinder gearshift connects respectively two solenoid valves, the filler opening of six solenoid valves connects the oil outlet of proportional pressure control valve simultaneously, the return opening of six solenoid valves is connected system return tube simultaneously, the filler opening connected system oil inlet pipe of proportional pressure control valve.This invention possesses three movement travel functions accurately.Not only can accurately realize 5 grades of AMT speed changers and enter shelves and move back neutral gear operation, can also effectively reduce shifting shock, improve shift property and reliability.The complex structure of this hydraulic system, and generally there is no ready-made hydraulic power in current compact car, thus this automatic transimission generally can only on large car, use, as city bus; Adopt the major defect of the staggered automatic mechanical transmission driving of two motors to be, it has a motor at least in the time that another motor carries out work, is mass motion.That is to say, in this structure, one of them motor is not only driving consumed energy in gear driving lever, also will be in the motion that drives another motor consumed energy.And in gearshift procedure, motor is constantly rocked, on thering is direct impact the working life of motor.And this speed changer is if realize hand from dual-purpose speed change, can only adopt two kinds of forms: the one, in the time of hand shift, drive motor rocks, and therefore needs operator firmly larger.Constantly rocking of motor, also to impacting its working life; The 2nd, in the time of hand shift, automatic shift system and manual transmission are thrown off, therefore, very trouble of its operation.
Summary of the invention
The present invention be mainly solve prior art existing automatic mechanical transmission complex structure, energy consumption is large, working life is short, be difficult to realize hand from the technical problem such as dual-purpose, provide a kind of simple in structure, energy consumption is little, long service life, can realize easily hand from dual-purpose Novel hand from interlock gearshift and controlling method thereof.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of Novel hand is from interlock gearshift, it is characterized in that, it comprises control system, be fixed on the motor on pedestal, driving lever oscillatory gearing mechanism, enter grade drive unit and a couple axle, described motor by a double sided clutch respectively with driving lever oscillatory gearing mechanism with enter a grade drive unit and be associated, described couple axle is connected with gear driving lever by a slide mechanism, described couple axle and this slide mechanism are rotationally connected, the pto＝power take-off of described driving lever oscillatory gearing mechanism is provided with a crank, the axle of this crank and couple axle is slidably connected, the side of described couple axle is provided with into a grade allocating slot, this enters the axial perpendicular inner side surface that grade allocating slot comprises former and later two and couple axle, the described pto＝power take-off that enters grade drive unit enters a grade crank and is connected with one, this enters grade crank and one and enters a grade shift fork and be rotationally connected, this enters grade shift fork and described to enter grade allocating slot suitable, the described grade shift fork that enters is the unidirectional shift fork only with the axial limiting ability to couple axle.Motor by a double sided clutch respectively with driving lever oscillatory gearing mechanism with enter a grade drive unit and be associated, refer to, the rotating shaft of the driving disc of this clutch is connected with the output shaft of motor, have the initiative dish both sides driven disc rotating shaft respectively with driving lever oscillatory gearing mechanism with enter a grade drive unit and be connected, when driving disc is shifted to the left and right sides, realize respectively motor power to driving lever oscillatory gearing mechanism and enter a grade drive unit transmission.In the time of gear shift, control system control electric machine rotation, and make clutch driving plate deflection driving lever oscillatory gearing mechanism, and make driving lever oscillatory gearing mechanism rotate an angle, make couple axle along an arc track transverse shifting, thereby drive driving lever to swing.In moving process, can be by there being a relative rotation between bent axle and couple axle, this motion mode needs between bent axle and couple axle not circumferential spacing at couple axle; Also can make couple axle have a process of rotating around its axle center, between this motion mode bent axle and couple axle, there is circumferential spacing of couple axle, and between couple axle and gear driving lever, there is the circumferential degrees of freedom along couple axle.In couple axle transverse shifting process, move certain distance by slide mechanism along driving lever, thereby realized the movement of couple axle and the swing of driving lever does not interfere with each other.In this process, enter grade shift fork and move along entering a grade allocating slot.Driving lever swing to into shelves relevant position time, clutch driving plate is partial to into a grade drive unit, driving lever oscillatory gearing mechanism quits work, entering a grade drive unit starts to rotate, it drives into a grade shift fork and moves, thereby drives couple axle axial motion, and then drives gear driving lever to realize into shelves.In the axial motion process of couple axle, couple axle can, with respect to the upper and lower deflection of gear driving lever, slide up and down along gear driving lever by slide mechanism simultaneously.
