A wheel suspension system and a method for controlling the system. The wheel suspension system includes a first axle provided with wheels and a second axle provided with wheels. The first axle is connected to a first driveshaft portion via a first differentialand the second axle is connected to a second driveshaft portion via a second differential. The system further includes angular speed sensors designed to detect the rotational speed of the axles, and/or the rotational speed of the respective wheels. The angular speed sensors are connected to an electronic control unit (ECU) which is designed to calculate a difference between the angular speed of the first and second axles, and/or a difference between the angular speed of the respective wheels by the use of input data from the angular speed sensors. The speed difference can be used as an indication of different wheel radius of the wheels. The system includes a coupling, e.g. a dog clutch arrangement, arranged in the driveshaft and positioned between the first and second drive shaft portions for changing the first and second drive shaft portions between being drivingly connected and disconnected.

Method and device for tandem- or multiple-axle drive for a vehicle

A low profile vehicular seat having an occupant contacting surface and a headrest which is moved from a first position to a second head reception position upon the communication of force from the body of the vehicle to the seat assembly.
