In the wheelchair for handicapped and sick patients, which is driven by an electric motor, each driven wheel (1) with its drive (2) is provided with a separate suspension relative to the chair frame (3), a telescopic spring in the form of a gas compression spring, a shock absorber or the like being provided as the suspension (4) for each driven wheel (1). The spring (4) engages with one end in a joint of the drive (2), seated on the wheel axle (6), and is secured by the other end in a joint (7) on the chair frame (3). In a preferred manner, the two rear wheels (1) are driven and are provided with a spring suspension relative to the chair frame (3). <IMAGE>
