The invention relates to a
dynamometer for an automobile
chassis, aiming at solving the shortages that the existing
dynamometer for the
chassis has unstable detection data, low accuracy and poor reliability, is difficult to correctly evaluate the
power performance of the vehicle and the like, and the defects that the
dynamometer can not realize the compatibility of
power performance detection function and emission inspection function. The invention provides a dynamometer for the automobile
chassis, comprising a stander, an anti-drag motor, an
eddy current machine, a force measurement sensor and a speed sensor arranged on the
eddy current machine, and a pair of driving roller and driven roller linked to each other; two ends of the driving roller and the driven roller are rotatablely connected on the stander by a bearing respectively; the driving roller is connected with the
eddy current machine and the anti-drag motor; and the force measurement sensor adopts a dual-range sensor. The invention provides a measurement and control method for the dynamometer used for the automobile chassis. The dynamometer for automobile chassis and the measurement and control method thereof have stable detection data, high accuracy and good reliability and can realize the compatibility of the
power performance detection function and emission inspection function.
