Background technology:
Brake system of car is one of most important system in the vehicle safety travel.Along with the development of engine technology and the improvement of road conditions, the moving velocity of automobile (kinetic energy promptly travels) has increased significantly, traditional friction-type brake apparatus more and more can not satisfy the requirement of running car, all kinds of automobiles of urban bus and hills, mountain area operation, owing to frequently or for a long time use service braking system, the brake efficiency heat fade phenomenon that the meeting appearance causes because of friction lining is overheated causes braking failure when serious, threaten traffic safety.Vehicle has also improved operation cost because of frequent brake relining and tire.In order to address this problem, various vehicle auxiliary braking systems have obtained to develop rapidly, and wherein hydrodynamic retarder also will become to take as the leading factor scheme at home in Europe, the United States.Its principle of work is with oil pump or pressurized air the fluid in the petrol storage tank to be pressed in the turbine transformer, making the rotor that is installed on the transmission shaft drive fluid rotates around axis, fluid moves along the rotor blade direction and gets rid of stator to being fixed on the chassis, stationary blade is to the antagonistic force of fluid, change the liquid flow path direction, go back to impact rotor again, formed resisting moment to rotor, act on the transmission shaft, thereby realized braking (deceleration) function of no rigidity friction pair effect, the big portion of vehicle energy is converted into the heat energy of fluid in this process, makes oily temperature rise or is taken away by the medium of H Exch.Because of the good auxiliary braking effect that hydrodynamic retarder had, current hydrodynamic retarder is applied on heavy-duty truck and the large and medium-sized passenger vehicle more and more.Should need and give birth to, the company of a lot of production hydrodynamic retarders occur, as the VOITH of Germany, the TELMA of France, the general and Japanese companies such as TBK of the U.S., at present in countries such as Europe, the United States, hydrodynamic retarder has become absolute main flow.Though China is in the research and development of retarder and use existing certain development, compares with advanced person's country and still have big gap.
All kinds of retarders (current vortex, fluid power etc.) of practice all are by different way automobile kinetic energy (or potential energy) to be converted into heat energy to be dispersed in the air both at home and abroad at present, the kinetic energy of automobile obtains by the energy that expends various preciousnesses, and the loss in vain of this energy is very unfortunate.
It should be noted, kinetic energy in the time of reclaiming automobile brake and the hydraulic hybrid dynamic automobile that utilizes are again frequently braked at needs, all kinds of city buses of starting, obtain Preliminary Applications in waste-skip and the express delivery car, obtained the considerable energy saving emission reduction effect, and many technical schemes appear, as the patent No. is 87100344, ZL88214287.9, ZL200420059673.6, ZL200620040083.8, ZL200620044935.0, ZL200620044934.6, ZL200720073344.0, application number is 200910045677.6 or the like, though they show the effect of the hydrodynamic retarder with energy-saving and emission-reduction function to a certain extent, still can not ideally substitute and be currently available for the more advanced hydrodynamic retarder that close on square more.
Summary of the invention:
The task of automotive energy-saving emission-reducing hydraulic retarder of the present invention, just provide a kind of simple and practical, can reclaim automobile brake kinetic energy and when starting (or afterburning), again kinetic energy is used and can better realizes having concurrently the hydrodynamic retarder of energy-saving and emission-reduction and slow function, its accumulation of energy, exergic transfer of energy be without the mechanical system of former change speed gear box, but directly output shaft of gear-box is linked to each other with automobile axle by power-transfer clutch.
Technical scheme of the present invention is: at the mouth of automobile gearbox 18 odd-side 15 (or be the novel change speed gear box of one with their unitized design) is installed, oil pump/oil motor 12 is by the electromagnetism that can dynamically engage (or pneumatic, hydraulic pressure) power-transfer clutch 14, be installed on the odd-side 15, by one group of gear 16, link to each other with the output shaft 17 of automobile gearbox 18.The import of oil pump/oil motor 12 is leaded up to check valve 6 and shutoff valve 4 to lamina membranacea piston sealed reservoir 5; Another Lu Jingyi big two two energising magnetic ball valves 7 are to energy storage 10, and in parallel with it is also to lead to energy storage 10 through little two two energising magnetic ball valves 8 and flow regulating valve 9; Pressure transformer 11 detects and the output system pressure signal, and the outlet of oil pump/oil motor 12 is leaded up to check valve 13 to energy storage 10; The controlled overflow unit K that another road constitutes through the inserted valve 20 of pilot proportional by pass valve 19 and 1 control of two two-way electromagnetic valves, and get back to lamina membranacea piston sealed reservoir 5 through cooling mechanism 2 and filter 3.
Their working process and state are as follows:
(1) normal vehicle operation: when following in limited time when exoergic (promptly can not) that the energy storage internal pressure is in setting, magnetic clutch 14 outages be thrown off, native system and automobile gearbox disengagement, and oil pump/oil motor does not change, and native system is in off working state.
(2) system's accumulation of energy vehicle is slow brakes until stop (pulling in as city bus): under neutral gear (or non-neutral gear) state, when driver's pedal that gently touches on the brake, before the original brake system of access failure automobile, magnetic clutch 14 is engaged, vehicle inertia drives oil pump 12 by output shaft 17 conversely and rotates, make 1 energising of two two-way electromagnetic valves after the of short duration time-delay, cut off the oil return of inserted valve 20 control chambers, overflow unit K is in the control of guide proportion by pass valve 19, press the maximum oil pressure relief work of default, oil pump 12 enters energy storage 10 with pressure oil by check valve 13, the oil pressure that the oil pump outlet raises has rapidly formed the resisting moment of rapid increase, make car retardation, vehicle energy is converted into pressure energy in the energy storage 10.When the pressure in the energy storage 10 arrives the maximum oil pressure relief of setting, if vehicle does not stop as yet, the accumulation of energy process finishes, the fluid of pump output backs down inserted valve 20 (the overflow unit is in the maximum pressure underflow stream) and through apparatus for supercooling 2, filter 3 and shutoff valve 4 oil sump tanks opened under high pressure conditions, system remains under the state of high resistant moment, continues the performance brake action until parking.If will more stop or the need sudden stop in the short range, the pedal that touches on the brake under the driver only need continue is enabled the original mechanical braking sytem of automobile and is braked faster or emergency brake, and this moment, two systems acted on simultaneously, realize stronger braking, will reduce but reclaim automobile kinetic energy.
(3) system's exoergic vehicle launch (acceleration): vehicle is (neutral gear or non-neutral gear) under idling or flameout state, when the light accelerator pedal of driver, magnetic clutch 14 is engaged, the 8 charged conductings of little two two energising magnetic ball valves, energy storage internal pressure oil enters the outlet of big two two energising magnetic ball valves 7 and the import of oil motor 12 through flow regulating valve 9, this place's oil circuit pressure is raise, open big Solenoid ball valve 7 after the of short duration time-delay again, therefore the inlet outlet pressure differential of big Solenoid ball valve 7 is less the time, eliminates or reduced the hydraulic efficiency impact of exergonic process.The outlet fluid of oil motor 12 is through the overflow unit K and the cooling vessel 2 of unloading condition, filter 3 and the shutoff valve of opening 4 are got back to fuel tank, act on the oil pump (this moment for oil motor operating mode) 12 from energy storage 10 pressure oil that comes out, make oil motor 12 rotate (with the accumulation of energy process time oil pump turn to identical), drive output shaft 17 by the gear cluster in the odd-side 15 16 conversely and form the moment that the promotion vehicle advances, make vehicle launch and acceleration, the vehicle energy regeneration that glancing impact disappears, part reverts to the kinetic energy of vehicle, and this exergonic process can make the vehicle under the flameout state obtain the initial velocity of energy compression-ignition engine.Power-assisted during vehicle launch will make engine operating condition be greatly improved, and the black smoke when having eliminated starting has reduced discharge of harmful gases.
(4) accumulation of energy of system elder generation is kept slowly again: when vehicle on the hills or the long and steep downgrade section in hill path when travelling, system, control circuit is switched to the servo-actuated state of guide proportion by pass valve, when driver's pin is gently stepped on system car pedal, before the original brake system of access failure automobile, make 1 energising of two two-way electromagnetic valves, cut off the oil return of inserted valve 20 control chambers, overflow unit K is in the follow-up control of guide proportion by pass valve 19, in accumulation of energy, the fluid of pump output backs down inserted valve 20 and cooling mechanism 2 under the servo-actuated pressure state control of guide's apportioning valve 19, filter 3 and shutoff valve 4 oil sump tanks of opening.During descending, the output of car speed sensor can compensate the electric signal of guide proportion by pass valve 19 as feedback signal, when the descending speed of a motor vehicle surpasses setting value, feeding back to guide proportion electromagnetic valve 19 raises the oil pressure relief of overflow unit K, increasing acts on the resisting moment on the oil pump, and the speed of a motor vehicle is reduced; Otherwise, when the descending speed of a motor vehicle is lower than setting value, feeds back to guide proportion electromagnetic valve 19 overflow unit oil pressure relief reduced, reduce to act on the resisting moment on the oil pump, the speed of a motor vehicle is improved, thereby make the descending speed of a motor vehicle basicly stable in the scope of setting, make vehicle when descending, have constant velocity characteristics.Continuous descending on long steep grade, the potential energy consumption of vehicle has in the corresponding big or small pressure differential overflow in import and export, and the heat that is converted into liquid is sizable, and oil return is necessary through apparatus for supercooling.The slow resisting moment that native system provides (on the wheel) can reach thousands of N-m, in the time of satisfying vehicle substantially and run in the mountain area to the requirement of retarder, but and the also fuel-economizing power-assisted when vehicle transfers upward slope to and maybe need quicken of the energy in the energy storage.
(5) system throws off; When not needing this system works or system's et out of order, the driver can turn-off the power supply of magnetic clutch, and the oil pump/oil motor 12 and the output shaft of change speed gear box 18 are thrown off fully.At this moment, the hydrodynamic retarder that is arranged in parallel with the vehicle main gear is in the quiescence of inoperative, travels but driver's operating and controlling vehicle original system carries out routine.
The power-transfer clutch 14 of automotive energy-saving emission-reducing hydraulic retarder of the present invention, it is installed between odd-side output shaft and the oil pump/oil motor, can dynamically engage (or disengagement) at any time, and it is many Ortlinghaus plate clutchs (air pressure or electronic or fluid power all can).In the vehicle ' process,, make this system participate in energy storing brake, slow or exoergic is afterburning automatically by the subtracting of driver, acceleration purpose.Avoid this system to do useless idle loop, not only can prolong system life but also also reduce the invalid loss of motor vehicle fuel to a certain extent.
With application number is that 200910045677.6 invention is compared, and their hydraulic efficiency pressure system principle is identical, but the position that is installed in change speed gear box is different.Preceding invention is mounted on the power taking window of the existing side of change speed gear box (or rear end), utilization is installed in the existing power takeoff of change speed gear box tween drive shaft or the power-transfer clutch of special-purpose dynamically combination links to each other with native system, its shortcoming is that accumulation of energy and exergonic process must be on gears, by the synchro transfer torque, increase the extra duty of change speed gear box, especially aggravated the wearing and tearing of synchro; The present invention directly links to each other system by odd-side with output shaft, accumulation of energy and exergonic process can be not by other gear and the synchro of change speed gear box, so shelves or neutral gear all can, not only help the service life of change speed gear box, and improved the mechanical efficiency of transmission.
The characteristics of automotive energy-saving emission-reducing hydraulic retarder of the present invention are: recovery section kinetic energy and be used for starting and afterburning in the slow process of braking.Its benefit is: in parallel with the automobile gearbox output shaft, in conjunction with or throw off conveniently, can throw off when there is fault in system, but vehicle cruising still; Its accumulation of energy, exergic transfer of energy be without the mechanical system of former change speed gear box, but directly output shaft of gear-box is linked to each other with automobile axle by power-transfer clutch, alleviated the load of change speed gear box; Remarkable energy saving effect is arranged; Exoergic reinforcing when vehicle launch has improved the operating mode of driving engine, has reduced discharge of harmful gases; Can strengthen starting speed, improve efficiency of operation; It is slow into flexible fluid power to become the mechanical rigid braking, when improving travelling comfort, has prolonged the service life of system of vehicle transmission and brake system, has improved the safety performance of vehicle; Adopt mature now hydraulic technique and quantity-produced Hydraulic Elements, simple and reliable, the low cost of manufacture of system is easy to apply.
