An electrical drive for a wheel hub of a motor vehicle, especially a utility vehicle, is provided with an electric motor disposed inside of the wheel. The electric motor has a stator and a rotor, where the rotor is connected to a step-down transmission. Additionally, the drive is provided with a brake. The stator is disposed within the hollow rotor and the step-down drive is disposed within the stator.

Regulation of the driving and braking of vehicles equipped with a plurality of single wheel drive and brake unit modules, controlled by control processing circuitry, that act on the guiding function of the wheels includes coupling in pairs control processing circuitry associated with the individual single wheel drive and brake unit modules, the pairs of modules being symmetrically disposed with respect to a plane of the vehicle. The degree of coupling is dynamically changed.

The invention relates to a safety system on track guidance lines for optionally track-guidable or road-going vehicles with pivotable feeler rollers. To avoid accidents which may be caused by travelling on track guidance lines with feeler rollers not extended or only incompletely extended, the invention provides for there to be a switch, which can be operated by the feeler rollers, to be arranged on each of the two transverse guide barriers, approximately opposite each other on the same level as the feeler rollers of the vehicle, at the beginning of the track guidance line. These switches, if operated together, switch via a control unit an optical display device, located downstream of the switches in the direction of travel of the vehicle, and normally indicating a block signal, to 'clear line'.

Safety system on track guidance lines

A steering mechanism with time derivation wherein a servo member dependent upon an angular velocity of a steering wheel is connected in the manner of a gear system by means of a summing gear mechanism with a servo member dependent on an angle of the steering wheel turn and also with a servo member dependent on an angle of the wheel turn of steered vehicle wheels. A gear element of the summing gear mechanism pertaining to the servo member dependent on the angular velocity is supported toward a housing by way of a resilient support. The servo member dependent on the angular velocity is positively turned off with respect to its action on the summing gear mechanism if the steering wheel angle exceeds a specific limiting angle.

A positive guide system for road vehicles equipped with non-deflectable rear wheels, in which guide elements are arranged at the same distance in front of and to the rear of the rear axle, as viewed in the vehicle longitudinal direction.

Positive guide mechanism for road vehicles with non-turnable wheels

A steering mechanism with time-rate action for vehicles, which includes a first adjusting member having an adjusting path dependent on the wheel deflection angle which is coupled with the steered vehicle wheels, a second adjusting member with an adjusting path dependent on the angle of the steering wheel deflection which is coupled with this steering wheel and a third adjusting member having an adjusting path dependent on the angular velocity of the steering wheel deflection which is coupled with the steering wheel by way of a mechanism producing an adjusting magnitude dependent on the angular velocity of the steering wheel deflection, whereby the second adjusting member is gearingly connected without interposition of any elastic means with the steering wheel as also with the two other adjusting members by way of a summation gear.

Steering mechanism with derivative action timer

A system for compensating forces acting on a rapidly moving vehicle transversely to its driving direction, such as transverse acceleration forces and yaw angle forces as well as possibly roll movements, by means of torques applied to the steering wheel, in which measured magnitudes of certain degrees of freedom which are detected as second derivatives with respect to time while driving, are combined with each other by an information converter and are converted into a torque which is transmitted in bypassing relationship to the servo-steering device and which signals by its occurrence to the driver the presence of disturbing forces and causes the driver to apply counter-forces; the servo-steering device is thereby so constructed that no torque stemming from the steerable wheels is transmitted to the steering wheel.
