Abstract
The invention relates to a self-propelled device for milling road surfaces with a vertically adjustable chassis, which carries a steerable travelling mechanism with at least one steering wheel and a rear pair of wheels with individual wheel drives and a drive unit for them and for driving a milling unit which is coupled to the drive unit and comprises a milling roller which extends transversely to the travelling direction, has a width smaller than the width of the device and is arranged off-centre with respect to the device, the traction of at least one wheel being modified in a way corresponding to at least partial compensation for the moment acting about the vertical axis of the device during milling.
