A vehicle brake testing dynamometer comprising a rotatable surface simulation member (36) having an annular cylindrical surface. Friction band means (44) are mounted on the cylindrical surface, and motor means (20) for rotating the surface simulation member (36). A sub-frame (46) is mounted adjacent the surface simulation member (36). The sub-frame (46) mounts at least one wheel testing unit (100) wherein the wheel testing unit (100) includes a carriage (62) movable in a radial axis to and from the surface simulation member (36). The carriage (62) mounts an individual vehicle wheel suspension including a tire, a wheel hub, a brake, and suspension damping means (103) whereby the carriage (62) can move towards and away from the surface simulation member (36) to bring the tire in contact with the friction band means (44) on the surface simulation member (36) and tangentially thereto. Means are provided for varying the position of the carriage (62), the relative speed of the simulation member (36), and the application or release of the brakes in order to simulate virtual running and braking conditions of the vehicle wheel suspension. |
