Abstract
A dynamometer with a vertical loading device belongs to a motor vehicle performance test device. The dynamometer comprises the vertical loading device, a measurement and control system, a roller, a base, a bearing, a rotation speed and torque sensor and the like. The dynamometer causes the vertical loading device to generate the corresponding vertical load according to the vehicle load and road spectrum which need to be simulated, and obtains the output rotation speed, torque, power, mechanical efficiency and the like of the tested vehicle according to signals of the rotation speed and torque sensor and the vertical load by operation, which facilitates to enhance the accuracy of indoor power measurement.
Description
Technical field
The present invention relates to a kind of dynamometer machine, belong to the performance of motor vehicle testing apparatus with vertical loading device.
Background technology
Adopt indoor measuring method machines motor vehicle to have characteristics such as cost is little, efficient height, but also have some shortcomings simultaneously, very limited as simulation to the vehicle actual operating mode.The chassis dynamometer that is used for indoor set motor vehicle Performance Detection at present has various ways, simulation to running conditions of vehicle mainly contains two kinds of methods, a kind of is to change the simulation that the cylinder moment of inertia realizes that vehicle energy changes by installing a plurality of flywheels additional, another kind is to produce the moment of resistance by electric current and magnetic field interaction to act on the simulation that realizes road resistance on the cylinder, but variation that all can not the simulating vehicle vertical load.
Summary of the invention
At the existing weak point of above-mentioned existing chassis dynamometer detection technique, the invention provides a kind of dynamometer machine with vertical loading device, can go out tested vehicle load and road spectrum variation at lab simulation, and then the output power of measuring vehicle under different loads and road spectral condition.
It is a kind of dynamometer machine with vertical loading device of design that the present invention solves the problems of the technologies described above the technical scheme that is adopted, and comprises vertical loading device, TT﹠C system, cylinder, pedestal, bearing, rotating speed and torque sensor etc.TT﹠C system is made up of computing machine, data collecting card and software program etc.Vertical loading device is a hydraulic system, and its fixed part is fixedlyed connected with pedestal.Cylinder is bearing on the bearing by its axle head, and bearing fixing is on pedestal.Rotating speed links to each other with an axle head of cylinder with torque sensor.
Test process is as follows: tested vehicle is reached cylinder, make wheel be positioned at the cylinder top, vehicle is reliably located.The tested vehicle drive system is by the wheel drive rollers running, and rotating speed and torque sensor pass to TT﹠C system with the corresponding signal of cylinder.TT﹠C system is sent instruction according to the carload and the road spectrum of required simulation, makes vertical loading device produce corresponding vertical load, passes to wheel and cylinder by car body, simulates the variation of wheel vertical load.The vertical load that TT﹠C system produces according to the signal of rotating speed and torque sensor and vertical loading device obtains the output speed, moment of torsion, power, mechanical efficiency of tested vehicle etc. by computing.
Compare with prior art, the invention has the advantages that: by vertical loading device, directly control the vertical load of tested vehicle, more accurate simulation tested vehicle vertical load changes, the accuracy that helps improving indoor measurement of power.
