1. A tricycle comprising a rear wheel (6) which is arranged in the longitudinal axis of the three-wheeled vehicle as well as two spaced front wheels (3, 4) which can be steered indirectly by a steering element via an intermediate steering column (2), wherein at least one wheel can be driven via a chain drive by operating pedals provided on a bottom bracket ball bearing receptacle (21) connected to the frame (1) of the tricycle, wherein the two spaced front wheels (3, 4) are attached to the axis of an axle element in such a way that these are offset with respect to one another relative to this axis, so that the one wheel with its wheel axle is positioned in front of the axis of the axle element in the travel direction (10) and the second wheel is positioned with its wheel axle after the axis of the axle element in the travel direction (10), wherein the two spaced front wheels (3, 4) and therefore also the frame (1) of the tricycle can be tilted depending on the rotation direction of the steering column (2) proportionally and thereby continually in response to the rotation angle resulting from the rotation of the steering column (2) when moving through a turn, in that the steering column (2) is, on one hand, connected with the axle element (8) via a connecting rod (31), with a multifunctional axle (14) positioned above the pivot bearing (15, 16) and attached to the axle element (8) and arranged above the axle element (8), which multifunctional axle (14) is operatively connected together with the axle element (8) and the wheel support (12) of the wheel (3) that is positioned in the travel direction (10) in front of the axle (7) of the axle element (8), and in that on the other hand, a fixed point on the frame (1) of the tricycle, which is formed proximate of the bottom bracket ball bearing receptacle (21), is connected via a second connecting rod (29) with the wheel support (13) of the wheel (4) that is positioned in the travel direction (10) after the axle (7) of the axle element (8), wherein one or both wheel supports (12, 13) are pivotally connected with the axle element (8).
