ABSTRACT:
A sideslip tester detects sideslip and scrub in a vehicle having a steering axle and one or more pairs of tandem axles. The sideslip tester has a runway having a measurement plate which is moved laterally with respect to its longitudinal axis as a tire of the vehicle passes over the measurement plate as a result of lateral forces acting upon the tire. A lateral movement sensor operatively connected to the measurement plate determines the amount of lateral movement of the measurement plate as the vehicle tire passes over the plate and provides an output corresponding to the amount of lateral movement measured. The sideslip tester can determine when it is presented with tandem axles. When it is presented with tandem axles, the sideslip tester will determine the scrub angle of the tandem axles to determine if they are parallel.
