Volkswagen Golf Service & Repair Manual: On a regulated roller dynamometer with contra-rotating rollers for four-wheel drive vehicles

Volkswagen Golf Service & Repair Manual / Brake system / Technical data / Brake test / 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.
