Abstract
A dynamometer machine with a vertical loading device belongs to testing equipment for the performance of motor vehicles. The dynamometer machine comprises the vertical loading device, a measurement and control system, a roller, a base, a bearing, and a rotating speed and torque sensor. According to the vehicle load and road spectrum changes needing to be simulated, the dynamometer machine leads the vertical loading device to generate corresponding vertical loads, and according to the signals and the vertical loads of the rotating speed and torque sensor, the dynamometer machine obtains the rotating speed, the torque, the power, the mechanical efficiency and the like of the tested vehicle through calculation, thereby being favorable for improving the accuracy of the indoor power measurement.
Description
Technical field
The utility model relates to a kind of dynamometer machine with vertical loading device, belongs to the performance of motor vehicle testing apparatus.
Background technology
Adopt indoor measuring method machines motor vehicle to have characteristics such as cost is little, efficient is high, precision 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 current vortex 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 utility model 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.
It is a kind of dynamometer machine with vertical loading device of design that the utility model 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.TT﹠C system is made up of computing machine, data collecting card and software program.Vertical loading device is a hydraulic system, and its fixed part is fixedlyed connected with pedestal.The cylinder two ends are bearing on the bearing by its axle, 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 variation 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.
The beneficial effects of the utility model are by vertical loading device, directly to control the vertical load of tested vehicle, more accurate simulation tested vehicle vertical load variation, the accuracy that helps improving indoor measurement of power.
