Description

A kind of Vehicle auxiliary drive method
Technical field
The present invention relates to automobile assistive drive technologies, be specifically related to a kind of Vehicle auxiliary drive method of assistive drive when storing vehicle braking energy and use it for starting.
Background technology
Vehicle needs braking brake and starting continually in the process of moving, existing car brakeing is all realized by the hydraulically powered brake clamp clamping brake facing coaxial with axletree usually, because brake relies on the friction between brake clamp and brake disc to complete, therefore, brake can cause the wearing and tearing of the brake equipment such as brake clamp and brake disc frequently, need in use for some time again to change, the inertia kinetic energy of vehicle in brake process is then converted into heat energy and wastes.In addition, when vehicle is reset after braking, the control ratio of throttle is more difficult, and throttle is excessive, not only increases the discharge of oil consumption and tail gas, and the accident such as easily to knock into the back; If throttle is too small, then driving engine easily stops working, and particularly when going up a slope, the control of throttle is just more difficult.
Inertia kinetic energy in order to absorb, when storing car brakeing, more common mode relies on the rotation of wheel oppositely to drag the rotation of a motor, allows electric power generation being stored in storage battery while increase vehicle drag.Such as, in Chinese patent literature disclosed a kind of " intelligent AMT change-speed box ", publication No. is CN101701625A, mainly utilize existing AMT change-speed box and planetary transmission system is set between friction clutch and engine crankshaft, this planetary transmission system comprises the sun wheel be coaxially connected with active friction plate, the pinion carrier be coaxially connected with bent axle, the gear ring closed with planet rotation browsing, also motor is provided with outside gear ring, motor shaft is provided with the motor gear with gear ring engaged transmission, sun wheel rotating shaft is provided with lockable mechanism, described change-speed box also comprises transmission control unit TCU, control unit of engine ECU, electric machine controller, driving engine car speed sensor and power-transfer clutch car speed sensor.When vehicle deceleration or descending run, kinetic energy inertia from vehicle passes through wheel back transfer to AMT change-speed box, and the power of final sum driving engine is delivered on motor jointly by planetary transmission system together, transmission control unit TCU makes motor run on Generator Status by electric machine controller, the electric energy that motor produces can charge to storage battery, thus reaches the effect reclaiming function processed.
But this type of mode is mainly applicable to vehicle at descending, deceleration etc. has the situation of longer braking distance, and practical significance is not had for the drag occurred frequent in driving process in general urban district, and it absorbs the electric energy stored also only just can be directly used in the traveling driving vehicle on electronic or oily electric hybrid vehicle, and for the vehicle of a large amount of gasoline driven, when starting work to be in state, namely electrical generator on car is being battery charge, extra additional charge is not needed under normal motoring condition, therefore, braking energy is changed into the practical oil consumption that electric energy can not reduce driving engine.
Chinese patent literature also discloses one " automobile slow traveling and assistant drive system ", Authorization Notice No. is CN100532168C, it comprises actuating unit, also be provided with power-transfer clutch, pool pump, fuel tank, radiator, flow regulating valve, described actuating unit is connected with the axle drive shaft of oil pump by power-transfer clutch, the oil outlet of pool pump is connected by pipeline with flow regulating valve, radiator, fuel tank successively, and fuel tank is connected with the oil inlet of oil pump by pipeline.When vehicle descending, this assistant drive system makes actuating unit be connected with the axle drive shaft of oil pump by engaging clutch, thus oil pump is rotated and exports high pressure oil, this high pressure oil is getting back to fuel tank after flow regulating valve, by regulating the aperture of flow regulating valve, the output resistance of adjustable oil pump, thus resistance when can increase vehicle descending makes it walk or drive slowly, and coordinate brake and drive system for vehicle with tow, improve safety performance.And when running into upward slope etc. and needing the situation of assistive drive, then utilize oil pump to promote oil motor and rotate, and travelled by oil motor assistive drive vehicle.But, can not braking energy be reclaimed when braking in technique scheme, and the energy of assistive drive is still from driving engine
Summary of the invention
The object of the invention is to overcome can not reduce engine consumption significantly and braking energy can not be directly used in the problem driving vehicle to travel on fuel vehicle existing for existing vehicle assistive drive mode, providing a kind of and braking energy in fuel combustion vehicle driving process directly can be absorbed, storing and being used for driving the Vehicle auxiliary drive method of vehicle launch.
To achieve these goals, the present invention by the following technical solutions.
A kind of Vehicle auxiliary drive method, comprises the steps:
A. when stepping on brake pedal vehicle and starting to brake, be connected to transmission output and the second clutch be associated with brake pedal engages, under the effect of inertia of vehicle, wheel oppositely drags change-speed box, and the mouth of change-speed box stores power transmission system drives one by second clutch and one and stores the accumulation of energy of power wind spring winding;
B. when loosen the brake terminates braking, the second clutch dialysis be associated with brake pedal,
If vehicle is now in Reduced Speed Now state, then store power wind spring rollback release elastic deformation energy, and by one can unidirectional delivery power help drive and transmission system by transmission of power to diff, drive vehicle traveling with auxiliary engine;
If vehicle is now in halted state, the controller Locking Device locking automatically controlled according to the signal control one of car speed sensor stores power wind spring, avoid its rollback voluntarily, then vehicle is started to walk again, the first clutch be arranged between driving engine and change-speed box transfers joint to by dialysis, controller engages signal according to the first clutch that the position transduser be arranged on first clutch sends makes Locking Device unlock, store power wind spring rollback release elastic deformation energy, and by helping drive and transmission system by transmission of power to diff, vehicle start is driven to accelerate with auxiliary engine.
What Vehicle auxiliary drive of the present invention adopted is mechanical energy storage mode, when car brakeing, the second clutch be associated with brake pedal engages, now the inertia kinetic energy of vehicle oppositely drags change-speed box rotation by wheel, and by second clutch with store power driving system and make to store the accumulation of energy of power wind spring winding, until vehicle stops, controller controls Locking Device by locked for the output shaft storing power driving system according to the stop signal of car speed sensor, thus avoids the rollback storing power wind spring; And vehicle is when again starting to walk, first clutch engages, driving engine progressively drives vehicle start by change-speed box, meanwhile, position transduser sends a first clutch and engages signal, Locking Device unlocks according to the signal received by controller, stores power wind spring so namely by helping drive and transmission system and diff to drive wheel, thus realizes the assistive drive to vehicle.If vehicle is braking deceleration in the process of moving, when brake pedal unclamps return, second clutch is dialysis thereupon also, store power wind spring and stop winding accumulation of energy, due to vehicle still under steam, thus Locking Device is failure to actuate, like this, the power wind spring of storing namely by helping drive and transmission system and diff auxiliary drive wheels, thus makes vehicle again accelerate.And vehicle is when normally travelling, owing to helping drive and transmission system can only unidirectional transmission power, the power exported by change-speed box thus can be avoided by helping drive and transmission system back transfer to storing on power wind spring.Because vehicle progressively accelerated from static in the starting stage, and driving engine can produce very large discharge and oil consumption at low speed start-up period, and the active friction plate of first clutch and thus can produce Relative friction because of velocity contrast between friction lining, thus first clutch is generated heat and accelerates its wearing and tearing, and the speed of starting is slow, when particularly travelling in busy urban district, need to brake continually, start to walk, thus increase oil consumption and discharge widely, and shorten the service life of first clutch.The present invention is by storing inertia energy during braking, simultaneously at vehicle start or when stopping braking again accelerating by the fault offset that stores out, with the starting of assistive drive vehicle and acceleration, thus effectively can improve the starting acceleration performance of vehicle, reduce the low speed torque requirement to driving engine, reduce oil consumption and the discharge of vehicle.Particularly, the power wind spring of storing allows larger deformation, thus can store more energy, by rational design, fully can absorb inertia kinetic energy during car brakeing, and in the braking stored-energy stage, the resistance of its elastic deformation progressively increases, be thus conducive to shortening stopping distance, realize quick, smooth-going braking, and helping in release the stage of driving, it helps the power driven to be then from large to small, is thus conducive to fast starting and the acceleration of vehicle.In addition, because it helps the energy driven to be converted by the inertia kinetic energy of vehicle completely, without the need to the power of consumption of engine, therefore can really realize saving energy and reduce the cost.
As preferably; the described power of storing driving system comprises the input shaft be connected with second clutch, the output shaft parallel with input shaft; input shaft is provided with driving gear; output shaft is provided with the driven gear engaged with driving gear; be provided with overload protecting mechanism between described driving gear and input shaft, between described driven gear and output shaft, be provided with one-way driving mechanism.

When normal vehicle operation, lock pin fits in lock groove under the effect regulating stage clip, when second clutch engages, when the power wind spring of storing starts to reel energy storage, lock pin plays the effect of an axle key, now, head conically lock pin can be subject to the component of an axis, when the torsion storing power wind spring reaches default maxim, axial component suffered by lock pin can overcome the elastic force of adjustment stage clip and skid off lock groove, thus make to produce between driving gear and input shaft to skid, when lock pin arrives and enters next lock groove, if braking terminates, then second clutch dialysis, the power wind spring of storing no longer reels accumulation of energy, if braking not yet terminates, then lock pin skids off again from lock groove, by that analogy until braking stops, thus effectively can avoid the overload storing power wind spring.Because the head of lock groove and lock pin is conical, thus avoids and occur directivity, can be simplified it and manufacture and assembling.Be screwed into the degree of depth by adjustment set screw, can adjust easily and regulate the elastic force of stage clip, and then the moment of torsion that adjustment overload protection device transmits.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention will be further described.
A kind of Vehicle auxiliary drive method of the present invention, it adopts Zhu Qu mechanism as shown in Figure 1, specifically comprises the steps:
A. when stepping on brake pedal vehicle and starting to brake, be connected to change-speed box 2 mouth and the second clutch 32 be associated with brake pedal engages, under the effect of inertia of vehicle, wheel oppositely drags change-speed box, and the mouth of change-speed box stores power transmission system drives one by second clutch and one and stores power wind spring 8 and to reel accumulation of energy;
B. when loosen the brake terminates braking, the second clutch dialysis be associated with brake pedal,
If vehicle is now in Reduced Speed Now state, then store power wind spring rollback release elastic deformation energy, and by one can unidirectional delivery power help drive and transmission system by transmission of power to diff 5, drive vehicle traveling with auxiliary engine;
If vehicle is now in halted state, controller Locking Device 9 locking automatically controlled according to the signal control one of car speed sensor stores power wind spring, avoid its rollback voluntarily, then vehicle is started to walk again, the first clutch 31 be arranged between driving engine and change-speed box transfers joint to by dialysis, controller engages signal according to the first clutch that the position transduser be arranged on first clutch sends makes Locking Device unlock, store power wind spring rollback release elastic deformation energy, and by helping drive and transmission system by transmission of power to diff, vehicle start is driven to accelerate with auxiliary engine.
For the ease of storing power wind spring and engine power to the combination drive of wheel, change-speed box passes through a train of reduction gears to diff transferring power, train of reduction gears comprises the driving bevel gear 41 being arranged on transmission output and the two-sided driven bevel pinion 42 be connected with diff 5, and driving bevel gear and two-sided driven bevel pinion wherein one side engage.When normal vehicle operation, first clutch engages, and the power of driving engine 1 is delivered to change-speed box by first clutch, is being exported after speed changer by mouth, again by being delivered on diff after driving bevel gear, two-sided driven bevel pinion, transmission of power is on wheel the most at last.It should be noted that, second clutch 32 is the power-transfer clutch often opened, and is associated between brake pedal and second clutch by connecting rod mechanism, or brake pedal is also by the joint of HYDRAULIC CONTROL SYSTEM second clutch.And train of reduction gears should be arranged on before second clutch, that is, the state of second clutch can not affect change-speed box to train of reduction gears transferring power, and when brake pedal is not operating, second clutch is in dialysis state, only have when vehicle needs braking, brake pedal action, second clutch just engages accordingly.
The power of storing driving system of the present invention comprises the input shaft 71 be connected with second clutch, the output shaft 72 be arranged in parallel with input shaft, input shaft is arranged driving gear 73, output shaft is arranged engage with driving gear driven gear 74, for the power that the stores wind spring 8 of stored energy and an automatically controlled Locking Device 9, store the output shaft of power driving system then by helping drive and transmission system to be connected with diff.
Help drive and transmission system to comprise to be arranged on store helping on power transmission output shaft drive driving gear 10, drive transmission shaft 11 with helping of be arrangeding in parallel of output shaft, be arranged on help drive on transmission shaft and with help helping of driving that driving gear engages to drive driven gear 12 and drive coaxial the helping of driven gear and drive bevel gear 13 with helping, help and drive bevel gear and engage with the another side of two-sided driven bevel pinion.Like this, when Locking Device release output shaft, storing power wind spring can rotate backward by driver output axle, and by intermeshing help to drive driving gear and help drive driven gear, help and drive bevel gear and two-sided driven bevel pinion and diff drives vehicle wheel rotation.Certainly, also need to arrange one-way driving mechanism helping to drive driven gear and help to drive between transmission shaft, to avoid the moment of torsion of change-speed box in normal vehicle operation by helping drive and transmission system back transfer to storing on power wind spring, one-way driving mechanism can adopt directional overrunning clutch or other there is the mechanism of identical function.
In addition, the Locking Device in the present invention can adopt electromagnetic brake one class can be automatically controlled closed type device, that is, when vehicle is flame-out stop time, Locking Device is in lockup state.Certainly, in order to control the action of Locking Device, we need to have a controller, a car speed sensor and a position transduser be arranged on first clutch, car speed sensor and position transduser are connected with the input end of controller respectively, the mouth of controller is connected with Locking Device, car speed sensor can export the signal of a vehicle stopping to controller, position transduser then can detect the state of first clutch.
When normal vehicle operation, second clutch dialysis, Locking Device is in release position, and the power of driving engine, only for driving vehicle to advance, cannot be delivered to by second clutch and store on power wind spring.
When vehicle carries out brake snub, first clutch dialysis, the second clutch be associated with brake pedal engages, and now the inertia kinetic energy of vehicle oppositely drags change-speed box by wheel and rotates, and by second clutch with store power driving system and make to store the accumulation of energy of power wind spring forward wind, rewind and stop buttons.And unclamp return vehicle acceleration traveling once brake pedal, second clutch is dialysis thereupon also, now store power wind spring and stop winding accumulation of energy, and rotate backward to release energy, like this, store the moment of torsion of power wind spring namely by helping drive and transmission system and diff auxiliary drive wheels, thus vehicle is accelerated again.
If when vehicle carries out stopping brake, first clutch dialysis, the second clutch be associated with brake pedal engages, now the inertia kinetic energy of vehicle oppositely drags change-speed box rotation by wheel, and by second clutch with store power driving system and make to store the accumulation of energy of power wind spring forward wind, rewind and stop buttons, until vehicle stops, now car speed sensor sends a stop signal to controller, position transduser then sends the dialysis signal of a first clutch, namely this Time Controller controls Locking Device by locked for the output shaft storing power driving system, thus avoid the rollback voluntarily storing power wind spring.And vehicle is when again starting to walk, first clutch engages, driving engine progressively drives vehicle start by change-speed box, meanwhile, position transduser sends the joint signal of a first clutch, Locking Device unlocks according to the signal received by controller, stores power wind spring so namely by helping drive and transmission system and diff to drive wheel, thus the starting of assistive drive vehicle.
Certainly, store power wind spring in order to avoid oppositely dragging when vehicle backing is braked, we can also arrange corresponding one-way driving mechanism between driven gear to output shaft.And in order to prevent the overwind storing power wind spring, we also need arrange overload protecting mechanism between driving gear and input shaft, overload protection device comprises some along point settings such as input shaft circumferencial directions, cylindrical-conical lock groove 61, the preferred amount of lock groove is 6-8, driving gear side end face axial one extends formation lock sleeve 731, certainly, driving gear and should be between lock sleeve and input shaft is rotationally connected, on lock sleeve, radial direction arranges the through pin-and-hole 63 to input shaft lock groove simultaneously, pin-and-hole is divided into screw near side edge section, a lock pin 64 is set in pin-and-hole slidably, the head of lock pin conically and fit in lock groove, be spirally connected in screw a set screw 65, an adjustment stage clip 66 is then set between the tail end and set screw of lock pin.Lock pin is pressed in lock groove with transmitting torque under the effect regulating stage clip, when the power wind spring of storing progressively tensioning, when the moment of torsion transmitted between input shaft and driving gear reaches certain value, the conical bottom surface of lock groove can promote lock pin and outwards moves and depart from lock groove, now namely produce relative rotation between driving gear and input shaft, thus avoid storing power wind spring and damage because of overwind.Be screwed into the degree of depth by adjustment set screw, can adjust easily and regulate the elastic force of stage clip, and then the moment of torsion that adjustment overload protection device transmits.Be understandable that, the diameter of pin-and-hole should be less than the path of screw, and the cylindrical-conical head of lock pin can arrange a round and smooth sphere, to reduce the wearing and tearing of lock pin head to input shaft surface.
Further; be arranged on the one-way driving mechanism between driven gear and output shaft that stores power driving system and the overload protecting mechanism be arranged between driving gear and input shaft also can adopt the single-direction transmission overload protecting mechanism be arranged between driving gear and input shaft to substitute, with simplified structure and installation.
Single-direction transmission overload protecting mechanism of the present invention comprises and integrally extends by driving gear side end face axial the lock sleeve 731 formed; lock sleeve periphery is radially arranged at least two outer large in little ladder chute 67; certainly; driving gear and should be between lock sleeve and input shaft is rotationally connected, and ladder chute answers decile to arrange on lock sleeve periphery.Stair-stepping locking slide block 68 is set in ladder chute slidably, with the slip of limiting lock limited slip block in ladder chute, thus between the end face and input shaft periphery of locking slide block, form a roller bearing hold space, roller bearing holds the locking roller bearing 69 that in space, setting is parallel with input shaft, and the end face of locking slide block is an involute cylinder, thus the radial distance between the end face of locking slide block and input shaft periphery is circumferentially increased at input shaft from side gradually to opposite side, when input shaft rotates backward, locking roller bearing is rolled to and is positioned at the roller bearing accommodation larger side of radial distance, space, locking roller bearing now can hold in space at roller bearing and freely rotates, thus input shaft and driving gear are separated, the power driving system of storing cannot transferring power.When input shaft rotates forward, locking roller bearing is rolled to and is positioned at the roller bearing accommodation less side of radial distance, space, the end face of locking slide block and the periphery extruding locking roller bearing of input shaft, rely on the friction force that extruding produces, input shaft can drive driving gear to rotate with forward transferring power.In addition, arrange corresponding sprue 60 at the open end of ladder chute, and between sprue and locking slide block, arrange adjustment stage clip 66, sprue is fixed on lock sleeve by screw.When transmitting torque is excessive; locking roller bearing makes locking slide block footpath draw back to the squeese pressure that locking slide block produces; friction moment between input shaft now and locking roller bearing is less than the required moment of torsion transmitted; namely produce skidding between locking roller bearing and input shaft and locking slide block, thus play the effect of overload protection.
Further, single-direction transmission overload protecting mechanism of the present invention also can adopt following structure:
First, with aforementioned schemes analogously, extended by driving gear side end face axial one and form a lock sleeve 731, lock sleeve periphery is radially arranged at least two outer large in little ladder chute 67, certainly, driving gear and should be between lock sleeve and input shaft is rotationally connected, and ladder chute answers decile to arrange on lock sleeve periphery.Stair-stepping locking slide block 68 is set in ladder chute slidably, with the slip of limiting lock limited slip block in ladder chute, thus between the end face and input shaft periphery of locking slide block, form a roller bearing hold space, roller bearing holds the locking roller bearing 69 that in space, setting is parallel with input shaft, and the end face of locking slide block is an involute cylinder, thus the radial distance between the end face of locking slide block and input shaft periphery is circumferentially increased gradually at input shaft to opposite side from side.With aforementioned schemes unlike, be stacked with a briquetting 62 in the dislocation of locking slide block tail end, and briquetting and locking slide block binding face bonded to each other is inclined-plane, the open end of ladder chute arranges sprue 60, arranges adjustment stage clip 66 between sprue and briquetting.In this programme, briquetting forms the structure of similar chock, make briquetting and larger friction force can be produced between locking slide block and ladder chute, thus the elastic force requirement that can reduce regulating stage clip, to reduce its size, and be convenient to it and install, it should be noted that, briquetting and locking slide block binding face bonded to each other should be as far as possible smooth.
Braking stored-energy of the present invention, starting help the process of driving, and details are as follows:
When vehicle is when normally travelling, second clutch dialysis, Locking Device is in release position, and the power of driving engine outputs to diff by change-speed box, to drive vehicle to advance, but cannot be delivered to by second clutch and store on power wind spring.
When vehicle carries out brake snub, first clutch dialysis, the second clutch be associated with brake pedal engages, now the inertia kinetic energy of vehicle oppositely drags change-speed box rotation by wheel, and by second clutch with store power driving system and make to store the accumulation of energy of power wind spring forward wind, rewind and stop buttons, auxiliary braking is produced to vehicle simultaneously, reduce the wearing and tearing of Vehicular brake device.And unclamp return once brake pedal, second clutch also dialysis thereupon, now storing power wind spring stops winding accumulation of energy, and rotate backward to release energy, like this, store the moment of torsion of power wind spring namely by helping drive and transmission system and diff auxiliary drive wheels, thus vehicle is accelerated again.
When vehicle carries out stopping brake, first clutch dialysis, the second clutch be associated with brake pedal engages, now the inertia kinetic energy of vehicle oppositely drags change-speed box rotation by wheel, and by second clutch with store power driving system and make to store the accumulation of energy of power wind spring forward wind, rewind and stop buttons, auxiliary braking is produced to vehicle simultaneously, until vehicle stops, now car speed sensor sends a stop signal to controller, position transduser then sends the dialysis signal of a first clutch, this Time Controller carries out logic operation according to above-mentioned two signals received and correspondingly exports a control signal, thus control Locking Device action, by locked for the output shaft storing power driving system, to avoid the rollback voluntarily storing power wind spring.
