Volkswagen Golf Service & Repair Manual: On a regulated roller dynamometer with contra-rotating rollers for
four-wheel drive vehicles
 Note
| The brake test must be performed on a controlled
contra-rotating single-axle roller dynamometer for four-wheel
drive vehicles. |
| “Contra-rotating” means that the dynamometer rollers of the
single-axle roller dynamometer are driven forwards on one side
and backwards on the opposite side. |
| The rollers drive the wheels of one axle in opposite
directions to avoid transmitting torque to the other axle. |
| “Regulated” means that the speed of the brake test stand
rollers is so controlled so that there is no difference in speed
during the brake test. |
| This prevents the transfer of a force through the stationary
wheels (not on the set of rollers) via the propshaft to the
rotating wheels on the rollers. |
| The forward rotating wheel is measured during the test,
which means two brake tests per axle must be performed. |
| The maximum test speed must not exceed 6 km/h. |
| The test rigs authorised by Volkswagen fulfil these
requirements. |
