Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a motorbike.

[Technology background]

Motorbikes generally have one front and one wheel, so they cannot stand on their own with both wheels, making them unstable and prone to overturning, which is one of the reasons why many motorbike accidents occur.

Therefore, in recent years, a motor pike with two rear wheels has been devised.
It's on sale.

[Problem that the invention seeks to solve]

However, since the three-wheeled bike is self-supporting, it has good stability, but because it is a three-wheeled vehicle, there are problems with cornering.

[Purpose of the invention]

An object of the present invention is to provide a motorbike with good stability and good cornering.

[Means to achieve the purpose]

In order to achieve the above object, in the present invention, at least one of the front and rear wheels is made into two wheels, and these two wheels are supported by separate forks via cylinders, respectively, and the two cylinders are communicated with each other.

[Effect]

Since a motorbike constructed in this way has at least three wheels, it can stand on its own, making it less prone to tipping over and increasing stability.In addition, when cornering, as the center of gravity shifts, it shifts from one cylinder on the inside of the corner to the other. As the medium moves, both cylinders expand and contract, and the shift of the center of gravity and the inclination of the vehicle body are smoothly balanced and the vehicle runs smoothly.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, this embodiment has two front wheels, each of which is supported by separate front forks 2a and 2b via cylinders 3a and 3b. 2a2b is connected to the handle 4. Both cylinders 3a and 3b are connected to a pipe 6 through a regulating valve 5 as shown in FIG.
The medium a passes through the pipe 6 and enters and exits the cylinders 3a and 3b in accordance with the reaction force P applied to the wheel 1a or 1b. As the medium a moves, the wheels ia and lb move up and down to follow the inclination of the vehicle body, as shown in FIG. The regulating valve 5 prevents sudden movement of the medium a to prevent the vehicle body from inadvertently tilting, and adjusts the flow rate appropriately and can stop the medium a as the case may be.

The cylinders 3a and 3b have a backup ring, a coupling, and an O-ring 7 at the lower ends of the forks 2a and 2b.
It has been incorporated as a rondo through etc. cylinder 3a,
3b is provided with an appropriate injection nipple so that the medium a can be injected.

Although the pipe 6 is shown schematically in the figure, it is usually
Pass through the forks 2a and 2b, and fork 2a 12b
Shock absorbers such as springs are installed as appropriate in the same way as before.

The medium 1 is preferably a liquid such as oil, but other gases or gas-liquids may also be used.

The embodiment is configured as described above, and when driving on a flat road R, almost equal reaction force P acts on both front wheels 1a and lb, so that both front wheels ia and 1 are applied as shown in FIG.
b rotates almost without any high or low parts.

When running on a flat surface, if there is a protrusion such as a stone, the reaction force P increases, and the front wheel 13 or 1 that hits the protrusion increases.
b rises, keeping the entire vehicle parallel, and stable driving is achieved.

Next 1. When the center of gravity shifts inward at corners,
As shown in FIG. 3, the inner wheel 1a rises, that is, the medium a moves from the inner cylinder 3a through the pipe 6 to the outer cylinder 3b, and the wheel ia
, 1b move up and down, the shift of the center of gravity and the inclination of the vehicle body are smoothly balanced, and the vehicle runs smoothly.

In the above embodiment, the front wheels are two wheels, but the rear wheels may be two wheels and can be moved up and down in the same way, or both the front and rear wheels may be
ζ It is also possible to use two wheels.

Further, as shown by the chain line in FIG. 1, an all-weather cowl 11 may be attached. The brakes can also be foot-operated hydraulic on three or four wheels.

In this way, if the vehicle has three or four wheels, there will be more room in the vehicle body, and independent seats can be installed in the driver's seat and the rear seat instead of the current tandem seat with a seat.

It also creates space for carrying some luggage, further expanding its use as a practical vehicle. Furthermore, the parking space is extremely small and convenient, making it easy to park even in the city.

〔Effect of the invention〕

Since this invention is configured as described above, stability is increased and
In addition, a motorbike with good cornering can be obtained.
