The oil pump motor is connected with the main speed reducer of the automobile through the hydraulic clutch. When the automobile is braked, the oil pump motor is connected with the main speed reducer of the automobile, and works as pump operating duty under the action of the inertia force of the automobile to pump the oil liquor in the oil tank into the energy accumulator. Then, the kinetic energy of the automobile changes into the hydraulic energy to store up.
Description
The utility model relates to a kind of regenerative apparatus of car braking energy.
At present many researchs have been done in the recovery of car braking energy both at home and abroad, but all failed a large amount of place in operations, its reason is the cost height, complex structure.Germany patent DE3031232 discloses a kind of regenerative apparatus of car braking energy.This device is by a hydraulic efficiency gear of being made up of high speed variable-displacement oil motor, change-over valve, energy storage and fuel tank.The high speed variable-displacement oil motor connects with speed-changing mechanism on being located at propeller-shaft by power-transfer clutch.In addition, on propeller-shaft, also be provided with another speed-changing mechanism and drive a control oil pump separately, in order to the mode of operation of control major loop.But this device is the high speed variable-displacement oil motor owing to what adopt, thereby messenger chain is longer, and driving efficiency is also lower.Secondly, the power hydraulic system and the control system of this device separate, and two speed-changing mechanisms will be set on propeller-shaft, not only complex structure, be difficult to arrange, but also to do corresponding change to the original structure of automobile.In addition, the cost of this device is higher also will be to hinder a major cause of applying.
Task of the present utility model is that a kind of simple in structure, car braking energy regenerative apparatus that cost is low is provided in order to overcome above-mentioned weak point of the prior art.
Task of the present utility model is to realize by following approach: the car braking energy regenerative apparatus that is provided has a power hydraulic system of being made up of energy storage, pressure oil tank, main reversing valve and low speed quantitative oil pump motor; A hydraulic control system that links and form by above-mentioned energy storage and the pressure oil tank oil cylinder by priority valve, shuttle valve and a hydraulic clutch of main reversing valve.Above-mentioned low speed quantitative oil pump motor connects with the driven cylindrical gear of automobile main reducer by hydraulic clutch.When automobile brake, the pressure oil in the energy storage enters the oil cylinder of hydraulic clutch by priority valve, shuttle valve, and oil pump motor is engaged with main reduction gear.Automobile inertial power is by main reduction gear and clutch transmits fuel feed pump motor, and this oil pump motor is with the work of pump operating mode, and the fluid of pressure oil tank is pumped into energy storage, and automobile kinetic energy is transformed into hydraulic pressure and can be stored in the energy storage.When vehicle starting, the change-over valve commutation, the high pressure oil in the energy storage drives the oil pump motor rotation, and drives the automotive wheel rotation by power-transfer clutch, main reduction gear.The oil pump motor of this moment is in the motor operating mode, and hydraulic pressure can be transformed into kinetic energy again and emit.
Below in conjunction with accompanying drawing content of the present utility model is described in detail.
Fig. 1 is the structural representation of an embodiment of the utility model.Wherein 14---by pass valve, 15---compression indicator.
Fig. 2 is the electrical schematic diagram of embodiment.
As shown in Figure 1: oil pump motor 1 adopts cycloid formula low-speed big oil motor.It links with energy storage 3 and pressure oil tank 4 respectively by a main reversing valve 2 and forms a power hydraulic system.In order to prevent the leakage of high pressure oil, a hydraulic control one-way valve 5 can be set between energy storage 3 and main reversing valve 2.The axle of oil pump motor 1 engages with driven cylindrical gear 9 on the automobile main reducer 8 by hydraulic clutch 6 and gear 7 being located on 6 of the power-transfer clutchs.Therefore as long as power-transfer clutch one engages, then automobile driving wheel 10 can drive oil pump motor 1 rotation, and promptly oil pump motor is sentenced the pump operating mode; Otherwise, but the rotation of oil pump motor 1 and 10 rotations of driving automobile drive wheel, promptly oil pump motor is in the motor operating mode.Two kinds of operating modes of oil pump motor change by a hydraulic control system.This hydraulic control system is made up of the oil cylinder 13 of priority valve 11, shuttle valve 12 and the power-transfer clutch 6 of energy storage 3, pressure oil tank 4, main reversing valve 2.Priority valve 11 can adopt electromagnetic valve, and its electric control theory as shown in Figure 2.Wherein switch 1K, 2K are installed in the play motion of automobile brake pedal respectively and on the Das Gaspedal.
The working process of this device is down:
When automobile brake, chaufeur steps brake pedal, switch 1K closure, and the magnet coil 1DC energising of priority valve 11, spool moves to right, and the pressure oil in the energy storage 3 enters in the oil cylinder 13 of power-transfer clutch 6 through the left end of priority valve 11 and shuttle valve 12.So oil pump motor 1 engages with automobile main reducer 8 by power-transfer clutch 6, and rotates under the drive of automobile driving wheel 10.Meanwhile, the spool that promotes main reversing valve 2 from the pressure oil of priority valve 11 moves to right, and pressure oil tank 4 is communicated with inlet 1 α of oil pump motor 1.Fluid in the fuel tank 4 are pumped in the energy storage 3, and automobile kinetic energy is transformed into the hydraulic pressure energy, and force car deceleration or stop.
When vehicle starting quickened, chaufeur stepped Das Gaspedal, switch 2K closure, the magnet coil 2DC energising of priority valve 11, spool moves to left, and the pressure oil in the energy storage 3 enters in the oil cylinder 13 of power-transfer clutch 6 through the right-hand member of priority valve 11 and shuttle valve 12, and oil pump motor 1 is engaged with main reduction gear 8.Meanwhile, from the pressure oil of priority valve 11 spool of main reversing valve 2 is moved to left, and check valve 5 is opened.Energy storage 3 communicates with inlet 1 α of oil pump motor.High pressure oil in the energy storage 3 drives oil pump motor 1 rotation, and then 10 rotations of driving automobile drive wheel, and hydraulic pressure can be transformed into automobile kinetic energy.
This device is owing to adopted low speed quantitative oil pump motor as energy conversion component, thereby driving-chain is short, transmission efficiency is higher. Hydraulic control system is not established independent control oil pump in addition in addition, but directly by the accumulator fuel feeding, so simple in structure, cost is lower. When hydraulic clutch engaged, the hydraulic coupling of its oil cylinder was consistent with the pressure of accumulator in this device, and this had both guaranteed the reliability of power transmission, can suitably reduce again the friction plate number of clutch. In addition, need not to change the original structure of automobile when adopting this device, thereby be particularly conducive in existing vehicle and install and use. This device is not limited in the application on automobile, also can use in the vehicle of other classifications.
