Problems solved by technology

[0003] In order to overcome the current shortcomings of bicycles, the present invention provides a bicycle with two front wheels that can be tilted. This kind of bicycle can maintain a static and fixed state, and it is not easy to tip over when riding. Its structure is relatively simple and light, and there are few mutual moving parts. , can ride upright or tilted when under force, and in the absence of external force, it will automatically return to the upright riding state. It has both the lightness of a two-wheeled vehicle and the stability of a tricycle. It is a bicycle replacement new species of

Embodiment Construction

[0009] In the figure, the telescopic shaft 8 is a non-circular vertical shaft, which is matched and slidably installed with the inner hole of the column oil cylinder 6. It can only move up and down in the axial direction, and will not rotate. It supports the positioning and positioning of the telescopic shaft 8 against the return spring 7. It moves up and down, and its lower end can also be equipped with a brake mechanism at the same time. The brake mechanism only needs to connect one side of the brake valley with the telescopic shaft.

[0010] In the figure, the column oil cylinder 6 is a hollow casing with a closed upper end and an open lower end, one side of its upper end has openings connected with the oil pipe 2, and the other side of its upper end is respectively fixed with a horizontal bracket, connected sequentially With fender, its hollow inner chamber lower end has an inner diameter as a non-circular cover, which is installed with non-circular telescopic shaft 8, so t...

Abstract

The invention relates to a bicycle which has double wheels at the foreside and inclines. A horizontal forestock top-beam and a forestock underbeam are respectively and symmetrically fixed under the forestock axle. The two ends of the forestock top-beam and the forestock underbeam are connected with a post oil cylinder paralleled with the two sides. Telescopic shafts of left and right sides are in the post oil cylinder. A spring bracket is connected to one side of the telescopic shaft and a horizontal forestock axle is connected to the other side. A reset spring set is mounted between the spring bracket and the forestock underbeam. A front wheel is mounted on the front wheel spindle. The upper sides of the two post oil cylinders are communicated by oil pipe which is provided with a valve. The bicycle is not easy to incline with simple and portable structure and little movable parts. The bicycle can be erectly and slantways ridden and automatically recovers to erectility. The invention not only has portability of double wheeler, but also has stability of the tricycle.

Description

technical field [0001] The invention relates to a bicycle, which is a bicycle with two wheels at the front, which can be tilted and balanced when riding. Background technique [0002] At present, ordinary bicycles have a wheel at the front and rear respectively. The bicycle with this structure is simple in structure and convenient to ride, but its disadvantage is that it is easy to tilt, and it is difficult to stop fixedly during riding. Once encountering rainy and snowy road conditions , easier to slip and fall, very unsafe, although some people have trial-produced motorcycles and bicycles with front double wheels and rear single wheels, but their inclined structures are all quadrilateral structures, and their structures are complex, with many moving parts, bulky and costly. higher. For this, there is no good solution yet. Contents of the invention [0003] In order to overcome the current shortcomings of bicycles, the present invention provides a bicycle with two front...
