Abstract: In the test device a tire is mounted to a rotatable spindle within a housing for selective engagement with a road wheel. The housing is supported and maneuvered by a number of vertical and horizontal members, each member including universal joints at its opposite ends to prevent bending moments from being applied to the members. Since only tension and compression forces are applied to the members, a very stiff load frame is provided for the test tire. One of the members comprises a linear actuator which is spaced away from the longitudinal axis of the housing to provide additional stability to the housing during testing. Load cells are connected to the member for the purpose of measuring the tension or compression variations due to the rolling engagement between the test tire and road wheel.
