Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a self-sustaining vehicle such as a motorbike, a light motorcycle, and a motorcycle with a power retractable auxiliary wheel such as a motorcycle, so that the motorcycle can be self-sustaining when the motorcycle is stopped and when the vehicle is traveling normally. The present invention relates to a motorized two-wheeled vehicle having auxiliary wheels that achieve both mobility and the like.

2. Description of the Related Art Generally, a motorcycle represented by a motorcycle runs on a curve with an inclination that keeps the centrifugal force and the gravity of the earth in equilibrium. It also has the advantage that kinetic energy loss due to unnecessary lateral friction with the road surface is smaller than that of a four-wheeled vehicle, and it does not require a differential mechanism such as a four-wheeled vehicle or a part of a three-wheeled vehicle. In addition to the effect of reducing the weight and reducing the weight, it also has an advantage that energy loss is smaller than that of the above-mentioned four-wheeled vehicle. On the other hand, the two-wheeled vehicle has a property that it is less self-sustaining at low speed than in normal traveling, and is not self-sustaining at stop. Therefore, in such a two-wheeled vehicle, it is indispensable to assist with the legs of the operator himself, and it is impossible to adopt a closed room or a room structure having a rainproof and windproof function like a four-wheeled vehicle. However, it is difficult to add the habitability and the backward function. In addition, in general, in the above-mentioned two-wheeled vehicles, the increase in vehicle weight accompanying the improvement in performance and function increases the burden of assistance by human legs, so that the expansion of user groups and applications is restricted compared to four-wheeled vehicles. There is also the current situation.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in order to cope with the above-mentioned situation, and an auxiliary wheel is provided on a powered motorcycle such as a motorbike or a motorcycle to stop at a low speed. In addition to ensuring the independence of the two-wheeled vehicle when the vehicle is moving backwards or backwards, and during normal driving, the auxiliary wheels are stored to maintain the original equilibrium characteristics of the two-wheeled vehicle so that the four-wheeled vehicle can be used as a habitat for the four-wheeled vehicle. The purpose is to combine both the maneuverability and the ease of operation with the maneuverability and economy of the two-wheeled vehicle.

[0004]

That is, the features of the motorized two-wheeled vehicle of the present invention which meet the above-mentioned object are as follows: First, an auxiliary wheel for supporting the two-wheeled vehicle in an independent state is provided on both sides of the motorized two-wheeled vehicle. This is because a supporting state in which it is grounded and a stored state in which it is raised from the supported state and stored are attached so as to be selectively performed. In this case, the auxiliary wheel is
The motorcycle is automatically controlled so as to be in the supporting state below a predetermined traveling speed and to be in the stored state above the traveling speed, and is provided with a spring mechanism that absorbs unevenness of the road surface in a vibration-proof manner, or on a sloping ground. It is also preferable that the left and right heights can be adjusted in order to vertically support the two-wheeled vehicle, etc., and claims 2 to 4 describe this. Further, a motorized two-wheeled vehicle having another auxiliary wheel of the present invention has auxiliary wheels that are automatically controlled on both sides of the motorized two-wheeled vehicle so as to always support the two-wheeled vehicle so that the vehicle is tilted corresponding to a running state. It is characterized by having. Further, in each of the above-described two-wheeled motorized vehicles, it is also preferable to install the power unit engine at the rear of the rear wheel at the center position in the vehicle width direction so that noise is not easily transmitted to the occupants. In the structure corresponding to claim 5, the auxiliary wheel is not a retractable type but is substantially a four-wheeled vehicle, but it corresponds to a running state (the inclination of the vehicle in which the centrifugal force acting and the dynamic balance are balanced). The vehicle's inclination is always controlled to ensure habitability and economy. That is, as a result, it is an automatic control four-wheel vehicle with deformation of the front, rear two wheels, and side two wheels.

[0005]

In the above-described motorized two-wheeled vehicle of the present invention, the auxiliary wheels are provided so that the self-supporting state can be secured without the assistance of the operator's own legs. by this,
Although it is a two-wheeled vehicle that is both manoeuvrable and economical, it is possible to adopt a closed room or a room structure that has a rainproof and windproof function, similar to a four-wheeled vehicle, making it an all-weather and all-climate vehicle that conventional motorcycles do not have. It is possible to increase the functionality and performance of the motorcycle because it is possible to obtain the applications and the number of users, and the restrictions on the increase in vehicle weight are alleviated. Be improved.
