ABSTRACT:
The invention relates to the measurement of the torque generated by the motor of a vehicle. According to the invention, the conventional rolling dynamometer or shaft-driven dynamometer is replaced with a load measuring means such as a strain gauge which is arranged to measure the torque reaction transmitted through the body of a motor when it is operated under load. Where the motor being tested is installed in a vehicle, strain gauges or other measuring means may be arranged to support the weight of the vehicle and measure changes in its weight distribution under the influence of the torque reaction of the motor. The apparatus may include computer means for calculating the torque and power output of the motor from the data supplied by the load measuring means.
