ABSTRACT OF THE DISCLOSURE A chassis, particularly for carrying a wheelchair with pivotal seat, fitted with ground-engaging wheels with at least one driven from a drive device through a drive transmission and with at least one steerably suspended and connected to a steering motor receiving steering signals for steering the chassis bearing while driving from a steering panel comprising steering control devices is described, whereby all steerably wheels are drive device driven and steerably suspended each being pivotal about a vertical steering axis geometrically maintained within or at a vertical plane comprising the wheel axis. By means of a between the steering axes arranged and these mechanically connecting steering transmission system including a herethrough for the pivoting of said steering axes connected steering driving device rotating the axes, and through the same direction of rotation, each steering axis is arranged able to pivot all said wheels about their steering axes, i.e. through mainly equally sized pivoting angles independently of the bearing of the seat or dependently being correlated therewith. A drive device can directly or through a drive transmission system with the same direction of rotation simultaneously rotate all wheels. A steering system hereto, mainly of electronic kind, is described.
