The invention relates to an improved suspension of steered wheels for all types of vehicles, especially single-track scooters which can be steered by means of weight transfer, having a front wheel and a rear wheel which are arranged one after the other approximately on one plane, at least one of the wheels being embodied in a steerable manner by means of steering mechanics, in addition to a frame connecting said wheels and comprising a surface for standing. The steering head angle of the steering head axis is varied in relation to the vertical or the normal of the ground, according to the steering angle of the steerable wheel and by means of the steering mechanics inside a predefined angle range. A first embodiment of the steering mechanics comprises three nested forks, the innermost steering fork holding and steering the steerable wheel, the middle articulated fork holding and steering the steering head bearing and thus regulating the steering head angle, and the outer fork being a fixed frame component. A second embodiment of the steering mechanics comprises a universal joint consisting of an articulated fork and a steering fork. The steering fork can be arranged in the centre of the wheel hub or radially offset therefrom, with an asymmetrical wheel rim and a normal wheel bearing or having an oversized wheel bearing inside a symmetrical wheel rim. A simple version of the scooter also has a steering head angle which is fixed at least during driving and which can be optionally regulated and fixed before driving, with the advantage that the steering system is positioned in the centre of the wheel hub (injury/attractive design). The aim of the invention is to provide an improved suspension of steered wheels for all types of vehicle, considerably improving the driving characteristics of the vehicle in such a way that the risk of accident for the user is greatly reduced. |
