Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further argumentation in detail:
In the drawings, the moving proving installation of electric vehicle fax is mainly by constituting with lower module: tested motor and controller 1 thereof, shaft coupling 2, rotational speed and torque tester 3, wheel box 4, mechanical inertia 5, dynamometer machine 6, Dynamometer Control device 7, central computer and data acquisition equipment, whole device adopts two-way to arrange, each module has and extraneous machinery and electric excuse, is responsible for the coordination control on each road by central computer.When doing performance test to electric vehicle fax is moving, if the electric vehicle of test is single motor-driven, can adopt wherein a road; If what the electric vehicle of being tested used is that many motors or Electric Motor Wheel drive, then can uses two-way simulating vehicle left and right transmission systems stressed, and finish by central computer control is coordinated in the loading of two-way.Central computer also is responsible for the monitoring of whole testing device, the signal that it is gathered comprises: by the electric current and the voltage signal of measured motor and controller 1, the rotating speed of rotational speed and torque measuring instrument 3 and dtc signal, the bearing temperature signal of wheel box 3 and the pressure and temperature signal of cold oil, the signal that the bearing temperature signal of mechanical inertia 5 and Dynamometer Control device 7 provide, these signals by sensor with the form of 0～10V voltage by the data acquisition system (DAS) collection, and handle by central computer, the duty of the whole testing device form with chart is presented on the graphoscope.The loading of dynamometer machine is set by the Dynamometer Control device, and the error between setting value and the actual test value is done signal Processing by central computer and obtained, and feeds back to Dynamometer Control device 7, realizes the accurate loading of electric vehicle electric drive system.Utilize bus that each module is done data acquisition and condition monitoring, reduced the length and the quantity of signal wire.
The inertia of proving installation loads and adopts mechanical inertia is main, the mode of electrical inertia compensation, and mechanical inertia can be adjusted, and loads different inertia according to different vehicles, and little inertia then adopts the mode of electrical inertia compensation.
3 matching effects of wheel box, measurement of power the equipment torque that can apply and rotating speed and the tested rotating speed of motor torque that can bear are mated mutually, its objective is that assurance can obtain thoroughly evaluating as the performance of moving testing of electric motors of electric automobile fax and controller thereof.For example, in the low speed high torque characteristic of testing of electric motors, can accurately load, can adopt the speedup function of wheel box, thereby the torque that can reduce dynamometer machine low speed loads requirement in order to guarantee measurement of power equipment; When the high speed constant output characteristic of testing of electric motors, when rotating speed of motor is very high, when surpassing the range of speeds that dynamometer machine can bear, can adopt the reduction of speed function of wheel box, so just can guarantee that the load that dynamometer machine applies is in optimum condition.After utilizing wheel box to finish rotating speed between tested motor and the measurement of power equipment and torque coupling, just can consider the loading of finishing under the prerequisite of gear ratio mechanical inertia, and do little inertia by electrical inertia and compensate.The principle that should guarantee in the test process is: consistent with inertia with the torque that the moving motor of this tested electric vehicle fax bears on the motor shaft when real road moves to the value on the motor shaft with torque conversion the inertia that loads, this principle is guaranteed by the central computer monitoring.Adopt the rotational speed and torque instrument accurately to measure torque and the rotating speed that loads on the live arbor.
Whole testing apparatus is placed on the cast iron workbench, and plant equipment utilizes fastening bolt or pressing plate to be pressed on the platform.Shaft coupling as rotary part will adopt protective cover, with protection operating personnel's safety.
