Steering mechanism of double-front-wheel bicycle

Abstract

The invention discloses a steering mechanism of a double-front-wheel bicycle, wherein a handle is fixedly connected with a handle shaft, and the handle shaft is installed in a front vertical tube. The steering mechanism of the double-front-wheel bicycle is characterized in that: a front protraction beam is arranged at the lower middle part of the front vertical tube, one end of the front protraction beam is welded with the front vertical tube, the other end of the front protraction beam is welded with a hinge tube, a rotating shaft is installed in the hinge tube and is inclined forwards for an inclination angle of 15 degrees to 25 degrees, the lower end of the rotating shaft is welded with the middle of a front axle, the two end parts of the axle are respectively provided with a front wheel, a return rod is welded at the middle of the front axle, the other end of the return rod is provided with a connection hole, a lug with a lug hole is welded at the front side of the lower end of the handle shaft, one end of a tension spring is connected with the lug at the lower end of the handle shaft through the lug hole, and the other end of the tension spring is connected with the return rod; and a side arm lever is welded at the left side of the lower end of the handle shaft, a connection hole is arranged at the other end of the side arm lever, a connection hole is also arranged in the front axle which is positioned at the same side with the side arm lever, and connection holes are respectively formed in the two ends of the connection rod and are respectively hinged with the connection holes in the front axle and the side arm lever through bolts.

Description

technical field [0001] The present invention relates to a bicycle, especially a steering device for a bicycle with double front wheels. Background technique [0002] At present, known human-powered bicycles or electric bicycles have developed bicycles with double front wheels, which improves the riding safety of bicycles. What existing double front-wheel bicycle adopted is the double front-wheel support structure, and steering performance is worse than common bicycle, and for improving the steering performance of bicycle, people have increased the steering mechanism of double front-wheel bicycle between handlebar and double front-wheel support. But there are technical deficiencies in the steering mechanism of the existing double front-wheel bicycle: the one, the structure is complex, and the steering of a single front wheel is like the steering of a common bicycle; Due to centrifugal force, it is easy to roll over in the opposite direction to the steering side, and there ar...
