Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the present invention equidistantly is symmetrically installed with a plurality of rolling bearing holders 14 in the both sides of table base 13, be fixed on the table base 13 with bearing seat set bolt 16, each is to installing driving drum 8 in the rolling bearing holder 14, the surface of driving drum 8 embeds is equipped with travelling belt 9, and a rolling bearing 7 is installed respectively at the driving drum two ends, and each is locked with a rolling bearing set nut 15, one end of first driving drum is a worktable torque output shaft 6, a sprocket wheel 17 is housed on the worktable torque output shaft 6, and link to each other with the dynamometer machine transmission shaft 4 of ac dynamometer 1 by driving flange 5, uniform four ring flange coupling bolts and set nut 18 on the driving flange 5, ac dynamometer 1 usefulness dynamometer machine set bolt 12 fixes on the ground; Last driving drum one end is equipped with a sprocket wheel 17, and links to each other with speed probe 2 by adapter sleeve 11; Middle each driving drum 8 all is equipped with two sprocket wheels; Sprocket wheel 17 usefulness driving chains 3 near travelling belt on sprocket wheel 17 on first driving drum and second driving drum link to each other, outside sprocket wheel 17 links to each other with outside sprocket wheel 17 usefulness driving chains 3 on the 3rd driving drum on second driving drum, sprocket wheel 17 usefulness driving chains 3 near travelling belt on the sprocket wheel 17 of the close travelling belt on the 3rd driving drum and the 4th driving drum link to each other, and the like, there is annexation in the sprocket wheel 17 on last driving drum with the sprocket wheel 17 of last cylinder; All be contained in a side of driving drum 8 with upper sprocket wheel 17, ac dynamometer 1 and speed probe 2.
The quantity of described driving drum 8 can be according to the length requirement increase and decrease of required measuring vehicle.The model of described ac dynamometer 1 is CAC-200 or CAC-250.The model of described speed probe 2 is SZMB-3, SZMB-or SZGB-4.
Principle of work of the present invention is as follows:
Motor vehicle slowly travels and goes up on the travelling belt 9 on driving drum 8 surfaces, guarantees that vehicle track is on the working surface fully, simultaneously vehicle body is fixed.
Vehicle startup afterwards, crawler belt begin to rotate, and drive travelling belt 9 entrys into service.Travelling belt 9 drives bottom driving drum 8 run-in synchronisms.When driving drum 8 rotates, drive cylinder transmission shaft 10 and drive sprocket 17 rotations, the synchronous rotary action of while driving chain 3, rotating speed is passed to speed probe 2 by adapter sleeve 11, speed probe 2 is given PC with measured data transmission, and, just can draw the real-time motion speed of crawler belt by converting.
Start ac dynamometer 1 simultaneously, progressively the increase exchanges output power of dynamometer machine 1, form with moment of torsion, by dynamometer machine transmission shaft 4, driving flange 5 passes on the worktable torque output shaft 6 of first driving drum 8, by the effect of driving chain 3 with drive sprocket 17, pass to cylinder transmission shaft 10, again by the friction force between driving drum 8 and the travelling belt 9, offer the resistance of motor vehicle crawler belt operation, the resistive torque that is provided when ac dynamometer 1 reaches the desired demarcation moment of torsion of motor vehicle, and when the motor vehicle crawler belt still can run well, illustrate that then the power of this motor vehicle is exported requirement up to specification, otherwise then against regulation requirement.By the conversion Calculation of rotating speed and moment of torsion, just can obtain the chassis output power of vehicle.
