Guidelines for front-wheel drive vehicles
•
Vehicles with several rigidly-coupled drive axles, or
those with tandem rear axles must be rolled using a free-
running roller set.
•
Vehicles with tandem rear axles coupled by a
detachable lock may only be rolled on a brake test stand
without using a free-running roller set.
•
Vehicles with drive axles linked by a load-dependent
differential lock e. g. a viscous clutch, may not be rolled
using a free-running roller set.
•
In the case of vehicles with acceleration slip regulation,
the ASR must always be switched off.
•
When rolling at higher speeds, (higher than 5 km/h) the
differential may be destroyed in the case of a stationary
axle.
•
In the case of vehicles with automatic transmission, the
vehicle manufacturer's prescribed towing speed may not
be exceeded.
◄
Important
If these guidelines are not adhered to, the vehicle may be
ejected from the rolling road test stand!
•
The 55 km/h (50 km/h ± 5 km/h) test speed may not be
exceeded.
•
Hand brakes that affect rear wheels must be put on, or
the rear wheels secured with wheel chocks where
necessary.
•
During the rolling procedure, the vehicle must be at a
90° angle on the rolling road and the front wheels must
be aligned in an exact straight line.
•
Hold the steering wheel steady when rolling
commences.
