（産業上の利用分野）
遊園地などの非公道走行用の小型遊戯車両の構造に関す
る。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to the structure of a small amusement vehicle for driving on non-public roads such as amusement parks.
（従来の技術）
従来の小型遊戯車両においては、路面と車輪との間の摩
擦係数を下げて滑りやすくし、限界旋回速度附近でのコ
ントロールを低速で安全に楽しむようにしている。(Prior Art) In conventional small-sized amusement vehicles, the coefficient of friction between the road surface and wheels is lowered to make them more slippery, so that control near the limit turning speed can be safely enjoyed at low speeds.
（発明が解決しようとする課題）
小型遊戯車両は、運転技術の未熟な人も運転するため速
度が増すと危険であり、一般の手法として最高速度を制
限したり機関の出力を下げたりしている。(Problem to be solved by the invention) Small-sized amusement vehicles are driven by people with inexperienced driving skills, so increasing the speed is dangerous, so the common method is to limit the maximum speed or reduce the engine output. There is.
しかし、楽しさも半減してしまう。However, the fun is also halved.
又、その改良案として前記路面を滑りやすくして走行す
る小型遊戯車両があるが、その欠点として制動力が弱く
、外壁又は車両同志で衝突する危険が多い。As an improvement, there is a small amusement vehicle that runs on the slippery surface of the road, but its drawback is that the braking force is weak and there is a high risk of collision with the outer wall or with other vehicles.
さらに旋回速度は路面と車輪の摩擦係数により、その摩
擦係数は路面状態と車輪によって変化するので旋回速度
の設定が困難であった。Furthermore, the turning speed depends on the friction coefficient between the road surface and the wheels, and the friction coefficient changes depending on the road surface condition and the wheels, making it difficult to set the turning speed.
本発明は、路面と車輪の摩擦係数を下げずに機械的に限
界旋回速度を自由に設定可能とし制動力は確実に得られ
るようにした。これにより、より安全に限界旋回速度附
近でのコントロールを楽しめる小型遊戯車両を提供する
ことを目的とする。The present invention makes it possible to freely set the limit turning speed mechanically without lowering the coefficient of friction between the road surface and the wheels, so that braking force can be reliably obtained. Thereby, the object is to provide a small-sized amusement vehicle that can be more safely controlled near the limit turning speed.
（発明が解決しようとする課題）
上記目的を達成するために、本発明の小型遊戯車両にお
いては、前後輪接地点の間に後輪回転軸を設けその回転
をスプリングなどの弾性体で規制しその弾性体により限
界旋回速度を設定可能とした。(Problems to be Solved by the Invention) In order to achieve the above object, in the small amusement vehicle of the present invention, a rear wheel rotating shaft is provided between the front and rear wheel grounding points, and its rotation is regulated by an elastic body such as a spring. The elastic body made it possible to set the limit turning speed.

る方向より外側へ向かってしまう。(Function) In general vehicles, as shown in Figure 1, V1 = μ・g"r...(1
), and the turning speed limit Vt is determined by the resistance coefficient μ between the wheels and the road surface, ignoring aerodynamic forces and road surface irregularities.If the turning speed exceeds the turning speed limit, the vehicle body will move outside the direction intended by the driver. I end up heading towards.

力ＦＡ、弾性係数Ｋにより自由に設定可能となることが
わかる。FIG. 2 shows the action of the small-sized amusement vehicle according to the present invention when turning. To simplify the diagram, it is assumed that the center of gravity is at the rear wheel rotation axis and that there is one wheel in both the front and rear wheels. The initial tension of elastic body A is FA
, where the elastic modulus is K, e= (FS FA) ・
K...(2)...(5) If the maximum steering angle of the front wheels is 02, the turning radius r is r = 1
1・sin θ2 + I, -cos θ2
It is expressed as fist tan (θ2-03)...(6). At this time, as the speed V increases within a range in which the centrifugal force F does not exceed the product of the mass W/g and the drag coefficient μ, the radius of rotation r becomes smaller. In other words, when the turning speed exceeds the turning speed limit, the vehicle body moves inward from the direction intended by the driver. Further, it can be seen that the turning limit speed can be freely set by the initial tension FA of the elastic body A and the elastic coefficient K.

The front wheels 1 are steered left and right by a driver rotating a steering wheel 2 . The rear wheels 3 are connected to a drive unit 4, an internal combustion engine 5, and a rear wheel steering shaft 7 fixed to a frame 6.
The rotation is regulated by a spring 8. The spring arm 9 rotates around the rear wheel steering shaft 7. For example, when the rear wheel 3 is steered counterclockwise, the right spring arm 9 rotates together with the rear wheel 3, and the reaction force of the right spring 8 is reduced. However, the left spring arm 9 does not move due to a stopper 10 fixed to the frame 6.
