Abstract
Apparatus for dynamometer testing of motor vehicles comprising load absorbing means in the form of a hydrostatic pump assembly which has an input shaft adapted to have a flexurally rigid engagement with a driven vehicle shaft using a rigid coupling. The coupling is mounted on an end portion of the pump input shaft which projects in one direction from a holder that supports the pump assembly. The pump assembly is mounted for limited rotational movement relative to the holder and projects in cantilever fashion in the other direction from the holder. A ground engaging support comprising support wheels is secured to the holder. A strain gauge assembly is connected between the pump assembly and the holder and serves to measure the torque applied to the holder by the pump assembly.
Claims10
Apparatus for dynamometer testing of motor vehicles, comprising a dynamometer having a stator, a rotor journalled for rotation in the stator and engageable with a driven vehicle power output shaft for rotation therewith, a stator holder supporting the stator and connected therewith to carry the torque loading on the dynamometer, and means for measuring the torque loading on the dynamometer, characterised in that the rotor (21) is provided with means (31) for flexurally rigid coupling of the rotor to the driven vehicle shaft adjacent one side of the stator holder (22), in that the greater portion of the stator (20) and the rotor (21) extend in cantilever fashion from the opposite side of the stator holder (22), and in that the stator holder is provided with a ground engaging support (35).
