Technical Field
The utility model relates to a rotatable axle technical field especially relates to a but radial axis of rotation based on tricycle.
Background
Typical bicycles are generally rigid body joints and generally have no other spring system than a vertical ground force spring suspension shock absorbing system for a mountain bike.
In addition, when the bicycle turns, the whole bicycle body can be seen as a rigid body (the handle and the front wheel can move but the degree of freedom of the plane of the bicycle body is not influenced), so that the whole bicycle body can be inclined leftwards or rightwards, the bicycle is easy to sideslip and fall down, the riding danger is increased, and the phenomenon is more serious particularly in rainy and snowy weather or wet and slippery road sections.
From the psychology perspective, the bicycle can feel that the bicycle is dangerous when inclining a certain angle because of the spontaneous subconscious protection and experience of people when turning, can restrict the user to control the bicycle, thereby the user experience of influence.
The common tricycle sacrifices the flexibility of the common bicycle and has relatively large volume. Chinese patent No. 106005119B's utility model discloses a balanced tricycle of seat absorbing rear wheel, the seat is arranged in the bumper shock absorber top, and the bumper shock absorber is fixed on the frame, though this design is not enough at the bicycle stability of solving to a certain extent, the poor characteristics of equilibrium, but its structure is comparatively complicated, and the seat shock attenuation does not have the flexibility of effectual promotion bicycle.
