The frame of the vehicle, which is capable of inclining in curves and preferably comprises a front wheel and two rear wheels, is rotatably mounted to a steering head beneath the driver's seat. Rigid driving elements are arranged in the area of this steering head, which couple the inclination of the vehicle frame to the opposite movements of the rear wheel swing arms by means of control elements in order to control the vehicle inclination and steer the rear wheels. In order to support the initial horizontal position of the tricycle, return springs are provided at the steering head, which force the rear wheel swing arms into a balanced mid-position. In slow vehicles suitable for rehabilitation purposes, the steering head beneath the driver's seat may be blocked by a brake in the starting phase. In faster vehicles, the movement of the rear wheel swing arms may be assisted by foot levers or manually operated hydraulic cylinders. |
