Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See Fig. 1-Fig. 3, upper as can be seen from figure, electric automobile continual mileage test board of the present invention, comprises pedestal 1, two drive roll 2, two follower rollers 3 and clamping device 4; Described two drive rolls 2 and two follower rollers 3 are installed on the pedestal 1 and can rotate around respective axis respectively, and wherein two drive rolls 2 are located along the same line and are connected by shaft coupling 5, and two follower rollers 3 are located along the same line and parallel with two drive rolls 2.The arrange in pairs or groups formation two group corresponding to two follower rollers 3 of two drive rolls 2, the spacing often organizing drive roll 2 and follower rollers 3 can support the driving wheel of automobile to be measured, to drive the drive roll in two groups and follower rollers to rotate respectively by two driving wheels of automobile to be measured; Wherein a drive roll 2 is connected with clamping device 4 by gear train 6, this clamping device 4 be connected with controller with exported by controller represent resistance torque size electric current to clamping device 4, make clamping device 4 export the resistance torque of needs to drive roll 2, resistance torque is for the running resistance of analog electrical electrical automobile on test road surface.Described clamping device is magnetic powder brake.
During measurement, first allow this test board on running car to be tested, and make driving wheel drop between drive roll and follower rollers; Then automobile is started, driving wheel drives main follower rollers to rotate, drive roll drives magnetic powder brake to rotate by gear train, magnetic powder brake produces resistance torque, magnetic powder brake is by changing size of current to export different resistance torques for the resistance of simulated automotive at road traveling, consume the mechanical energy of automobile output with radiating mode, thus realize continual mileage test.
Because cylinder is rotatable, automobile easily skids when passing in and out test board, between two groups of drive rolls 2 and follower rollers 3, be provided with back up pad 7 for this reason, back up pad 7 is arranged on the jacking apparatus 8 that is positioned under pedestal, jacking apparatus 8, for by back up pad 7 jack-up or put down, is beneficial to automobile driving wheel to be measured and is entered by back up pad or exit between drive roll and follower rollers.When automobile will enter test board, jacking apparatus by back up pad jacking to roller height roughly flush position, vehicle directly can be driven and enter, and driving wheel is contacted with follower rollers with drive roll.During test, then back up pad is put down.Be completed, when automobile will leave, then back up pad gone up, automobile directly can be driven and leave.Actual jacking apparatus 8 is air bag, and air bag is two, and back up pad 7 is arranged on air bag, is respectively used to the jacking of two back up pads, airbag aeration back up pad and jacking.For realizing the synchronous of two air bags, source of the gas by after filtering pressure reducing valve 9, then is connected with reversing solenoid valve 10, and reversing solenoid valve 10 exports and connects two air bags respectively by two-way pipeline, and pneumatic circuit is specifically shown in Fig. 4.
Because magnetic powder brake consumes automobile driving wheel by heating to rotate the mechanical energy exported, therefore thermal value is very large, for this this test board devises heat abstractor, to reach system heat balance, makes heating distribute as early as possible.Heat abstractor comprises radiator fan 11 and air baffle 12, and radiator fan 11 to be arranged on magnetic powder brake axle and towards fuselage direction; Air baffle 12 is arc shape, and magnetic powder brake is arranged in air baffle arc concave shape chamber.
Described pedestal is the framed structure that the longeron parallel with four by two parallel crossbeams is formed, four longeron two ends are arranged on two crossbeams respectively to make longeron and beam vertical, wherein the left side two longeron and the right two longeron respectively form one group of totally two longeron group, and two groups of drive rolls and follower rollers correspondence to be arranged in this two longerons group and parallel with crossbeam.
Described gear train 6 is belt gear, and be provided with small belt pulley in the drive roll end be connected with clamping device, magnetic powder brake axle is provided with big belt pulley, and small belt pulley is connected with big belt pulley by belt, and big belt pulley drives magnetic powder brake to rotate.
This electric automobile continual mileage test board can carry out the test of any model electric automobile continual mileage.Concrete method of testing is as follows.
1, by jacking apparatus, back up pad jacking is put in place, roughly equal with follower rollers highest point with drive roll.
2, by needing the vehicle carrying out testing to sail test board into, driving wheel is just in time dropped between drive roll and follower rollers.
3, bladder deflates, back up pad decline, driving wheel completely by two cylinder supports, as shown in Figure 5.
4, automobile is started, electric automobile driving wheel rotarily drives drive roll and follower rollers rotates, rotary torque is passed to the small belt pulley being arranged on drive roll end by drive roll, small belt pulley is by belt drive big belt pulley, big belt pulley drives magnetic powder brake to rotate again, magnetic powder brake damping torque stops that vehicle rotates, thus consumed work.
5, when electric automobile electricity exhaust do not rerun time, be completed, the mileage of record automobile instrument this process, be electric automobile continual mileage under test initial quantity of electricity state.
6, finally by jacking apparatus, back up pad jacking is put in place, automobile is sailed out of this test board.
Controller can control magnetic powder brake resistive torque, and resistive torque size is controlled by control inputs magnetic powder brake size of current, and the large resistance of electric current is large, and electric current slight drag is little.Controller is an intelligent controller, and the typical road spectrum that controller is experimentally collected controls output current size, makes the resistance be added on cylinder closely roll resistance and windage in actual road surface, and can control the resistance of output matching in real time.
During concrete operations, the electric automobile typical road power road spectrum obtained by real road test is converted thereof into by computing machine the resistance torque that magnetic powder brake is applied to cylinder, exporting the braking moment of different Current Control magnetic powder brakes by calculating controller in real time, so just making the situation of resistance close to real roads of test electric automobile.Fig. 6 is the electric automobile road spectrogram of actual collection.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
