The automobile chassis dynamometer system is mainly characterized in that the automobile chassis dynamometer system comprises a central control unit, a rotary drum device, a loading device and a sensor. Rotary drums used in the rotary drum device are two rigidly connected single rotary drums and are specially ground. The central control unit is used for receiving, analyzing and processing feedback signals and outputting control signals. A DC dynamometer motor in the loading device is connected with the rotary drums through couplings. The sensor comprises a fuel consumption meter, a temperature sensor and a flow meter. The utility model can improve the testing accuracy of the system, can test automobile tail gas emission, automobile fuel consumption and the like and can be used in fields such as automobile manufacturing, scientific research and the like.
Description
Technical field
The utility model relates to automotive performance test macro field, particularly a kind of dynamometer system for motorcar chassis.
Background technology
Chassis dynamometer is that the method by the simulated roadway driving cycle of getting on the car at indoor stand detects the various performances of automobile, but also can measure multi-state discharge index and oil consumption etc.At present, when auto manufacturing tests on indoor chassis dynamometer, the cylinder major part that often adopts in the drum apparatus on the chassis dynamometer system is a twin-roll, tire is compared on the road surface with contacting with it of cylinder, the pressurized situation differs bigger, slippage rate, resistance to rolling are big, so measuring accuracy is also relatively low.Even if some chassis dynamometer system adopts single cylinder, but cylinder surface mostly is bare-barrel drum, knurled roll, grooved drum or band coat cylinder etc., and its surface attachment coefficient is all relatively low, so also be difficult to the precision that reaches enough.In sum, existing roller frame is arranged unreasonable or the low not high problem of caused chassis dynamometer measuring accuracy of cylinder surface attachment coefficient is further improved.
Summary of the invention
The purpose of this utility model is to address the above problem, and provides a kind of and can improve the performance test precision, tests out the dynamometer system for motorcar chassis of the situation such as exhaust emissions, oil consumption of automobile simultaneously.Be achieved through the following technical solutions:
Dynamometer system for motorcar chassis described in the utility model comprises central control unit, drum apparatus, charger and sensor; The cylinder that adopts in the described drum apparatus is two rigidly connected single cylinders, and described cylinder is through special grinding.Direct current dynamometer motor in the described charger is linked to each other with cylinder by shaft coupling.Described central control unit is used for receiving, analyzing and handle feedback signal and export control signal.Sensor on described drum apparatus, the charger also comprises fuel consumption meter, temperature sensor, flowmeter.
The utility model is the advantage of prior art relatively:
1, the cylinder that adopts in the drum apparatus is two rigidly connected single cylinders, and tire is compared on the road surface with contacting with it of cylinder, and the pressurized situation is more approaching, and slippage rate, resistance to rolling are little, so the measuring accuracy height.
2, two rigidly connected cylinders that adopt in the drum apparatus, the surface is through special grinding, and its attachment coefficient more approaches the road actual conditions, has improved the precision of chassis dynamometer aspect the automotive performance test.
Description of drawings
Fig. 1 is the layout synoptic diagram of dynamometer system for motorcar chassis described in the utility model.
Embodiment
1,2-cylinder; The 3-dynamometer motor; The 4-torque sensor; The 5-central control unit; The 6-speed pickup.
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
As shown in Figure 1, dynamometer system for motorcar chassis described in the utility model comprises central control unit 5, the drum apparatus under the cylinder 1,2, charger under the dynamometer motor 3 and sensor 4,6 etc.; Described two cylinders 1,2 be rigidly connected and between a speed pickup 6 is installed; Described dynamometer motor link to each other with cylinder by shaft coupling and dynamometer motor 3 on torque sensor 4 is housed, speed pickup 6 and torque sensor 4 link to each other with central control unit 5 again, to measure corresponding rotating speeds and torque.In test process, the tach signal of cylinder 1,2 and the dtc signal of dynamometer motor 3 feed back to central control unit 5 by speed pickup 6 and torque sensor 4 respectively, feedback signal process central control unit 5 receives, conversion processing is analyzed again and the control signal of setting is exported to described dynamometer motor 3, to realize the simulation of dynamometer system to various operating modes.
Two rigidly connected single cylinders 1,2 that adopt in the described drum apparatus, tire pressurized situation is compared more approachingly with it on the road surface, and slippage rate, resistance to rolling are little, the measuring accuracy height; Two rigidly connected single cylinders 1,2 that adopt in the described drum apparatus, the surface is through special grinding, its attachment coefficient more approaches the road actual conditions, can greatly improve the precision of chassis dynamometer aspect the automotive performance test, to realize the simulation of dynamometer system, satisfy the various demands of scientific research, automobile making and detection etc. to various operating modes.
The utility model mainly provides single cylinder of road actual conditions is more approached on a kind of surface through special grinding, surface attachment coefficient dynamometer system for motorcar chassis; to improve chassis dynamometer in the precision aspect the automotive performance test; under the situation that does not deviate from the utility model essence; the structural arrangement of dynamometer system for motorcar chassis can be done corresponding change, but these corresponding changes should belong to all within the affiliated claim protection domain of the utility model.
