The invention relates to a steering system for an agricultural or
industrial utility vehicle, especially for a tractor. An electric drive
(22, 24) is provided for each half of an axle, preferably a front axle
(20), of the utility vehicle (10). Said electric drive can be driven by
at least one wheel (26) associated with the each axle half. The electric
drive (22, 24) can be controlled in such a manner that predetermined
torque can be transmitted from the electric drive (22, 24) to the wheel
(26) which is being driven. Preferably, the wheels (14) associated with a
mechanical drive axle, particularly a rear axle (12) of the utility
vehicle (10), can be driven by a mechanical drive (16, 18) of the utility
vehicle (10). The invention also relates to a method for operating a
steering system. The aim of the invention is to enable traction forces to
be transmitted by wheels (26) driven by the electric drives (22, 24),
even when the utility vehicle (10) negotiates bends, whereby particular
braking torque should be prevented on said wheels (26) in specific
steering angles. The torque which is to be transmitted to the wheel on
the outside of the bend is greater that the torque which is to be
transmitted to the wheel on the inside of the wheel in order to support
or effect the steering of the utility vehicle.
