Abstract

A powered mobile test device for measuring loads supported by a running tire, said device being composed of a rigid frame carried by at least two carrying wheels to which a torque is applied, and having an axle which is fixed to the frame and which carries a test wheel for measuring the loads supported by said tire. The axle is connected to the frame by a loading actuator, a torque is applied to the test wheel, said torque applied to the test wheel is in the opposite direction to those applied to the carrying wheels, and a linkage system between the test wheel and the carrying wheels transmits at least some of the power developed by the braking torque applied to the test wheel or by the braking torques applied to the carrying wheels.
