Problems solved by technology

Steering the two forks independently results in a flexible control of the two-wheeled vehicle, however straight-line running of the two-wheeled vehicle is thus made difficult because every movement of the driver's center of gravity is converted into a steering movement of the rear wheels

Embodiment Construction

[0077] exist figure 1 A side view of an embodiment of the invention is shown in , wherein the frame 1 has a front control tube 3 and a rear control tube 4 . On the front control tube 3 are rotatably mounted a front fork stem tube 5 with a front wheel fork 7 which receives the front wheel 8 and a steering rod 15 (on which the handlebar 16 is arranged). Furthermore, the front control pipe 3 defines a front steering axis 13 . The rear control tube 4 defines a rear steering axis 14 on which the rear fork stem tube 6 is rotatably mounted with the rear fork 9 receiving the rear wheel 10 . The corresponding steering axis is preferably the central axis of the corresponding control tube.

[0078] The front fork rod tube 5 is connected to the rear fork rod tube 6 via a coupling system 12 , wherein the rear fork rod tube 6 is rotatable as a function of the angle of rotation of the front fork rod tube 5 . The front steering axis 13 and the rear steering axis 14 tend to intersect each o...

Abstract

The invention relates to a bicycle having a frame (1) comprising a front head tube (3) that defines a front steering axle (13) and on which a front fork steerer tube (5) having a front wheel fork (7)that receives a front wheel (8), and a steering link (15) on which a handlebar (11) is arranged, is rotatably mounted, and a rear head tube (4) that defines a rear steering axle (14) and on which a rear fork steerer tube (6) having a rear wheel fork (9) that receives a rear wheel (10) is rotatably mounted, wherein the rear fork steerer tube is connected to the front fork steerer tube (5) via a coupling arrangement (12) and is rotatable in dependence of the rotation angle of the front fork steerer tube (5) and the front steering axle (13) and the rear steering axle (14) are inclined toward eachother and intersect underneath the handlebar (16).

Description

technical field [0001] The invention relates to a two-wheeled vehicle comprising a frame having a front control tube and a rear control tube, the front control tube defining a front steering axis and on which a front fork stem tube is rotatably supported together with a receiving Front wheel fork and steering rod for the front wheel on which the handlebar is provided, the rear control rod defining the rear steering axis and on which the rear fork rod tube is rotatably supported together with the rear wheel receiving the rear wheel A fork, wherein the rear fork stem tube is connected to the front fork stem tube by a coupling system and is rotatable in relation to the angle of rotation of the front fork stem tube. Background technique [0002] A two-wheeled vehicle, such as a scooter or a bicycle, with wheels arranged one after the other, usually has a steering lever with a handlebar which acts only on the front wheels and is actuated with the driver's hands. Since such two-w...
