Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a vehicle play system, and more specifically, the present invention relates to a vehicle play system, and more specifically, a system for learning driving skills by running a go-kart on a limited running course.
This invention relates to a vehicle play system that allows you to enjoy a thrilling feeling.

<Prior art and problems to be solved by the invention> In general, when driving a car on a rainy or snowy road surface, a frozen road surface, or a muddy road surface, it is common to apply sudden braking by stepping on the brake or to turn the steering wheel. If the vehicle is operated to suddenly change the direction of travel, the wheels may suddenly slip and the vehicle may lose control (the vehicle cannot be controlled as intended by the driver). Inexperienced drivers often cause traffic accidents due to the above-mentioned slips.

In other words, when a wheel slips, it is important to operate the steering wheel or brakes in response to the slip instantaneously to prevent a slip accident from occurring, or to minimize the occurrence of a slip accident. However, even if you are familiar with the above-mentioned slip response techniques as knowledge and theory, if you have not mastered them as so-called acquired techniques that have been memorized in your body, they will not be effective in reality. When faced with a slip phenomenon, it is often impossible to react reflexively, and as mentioned above, many traffic accidents occur due to slips.

However, at driving skills training centers, including general driving schools, only the learning methods for driving a vehicle under normal conditions on a normal road surface are taught; However, the reality is that there are no facilities or means to learn the instantaneous response operation techniques when slipping through real-life experience.

<Purpose of the Invention> The present invention has been made in view of the above-mentioned circumstances, and provides a novel vehicle play system that can actively cause the vehicle body to slip while traveling on a specific driving course. In addition to helping students learn driving techniques that allow them to reflexively respond to slips,
The aim is to allow drivers to enjoy the thrill of driving that they cannot normally experience.

<Means for Solving the Problems> A vehicle play system of the present invention for achieving the above object is comprised of a go-kart and a running course.

The above-mentioned go-kart has a self-propelled drive unit, a pair of drive wheels, and a pair of driven wheels, one drive wheel is made of normal tires, and all other wheels are The running course is formed in a predetermined shape and has a smooth surface that reduces friction with the slick tires.

However, the slippery surface of the running course may be one that reduces the friction between it and the slick tires by scattering powder, or it may be coated and impregnated with wax to reduce the friction between it and the slick tires. Furthermore, the friction between the tire and the slick tire may be reduced by coating and impregnating it with wax and further scattering powder.

<Function> With the vehicle running system configured as described above, the go-kart uses slick tires on all but one drive wheel, which can increase the contact area with the normal road surface and provide good road holding. Since the vehicle travels on a course with a slippery surface with the tires mounted on all other wheels, it is possible to create a situation where the road holding by the slick tires is insufficient, similar to when it rains or snows. It is possible to achieve sufficient road holding with regular tires, and when starting suddenly,
The vehicle body can be easily caused to slip when changing direction, braking, etc.

Furthermore, if the slippery surface of the above-mentioned running course is one that reduces the friction between it and the slick tires by scattering powder, it is also possible to reduce the friction between it and the slick tires by coating and impregnating it with wax. Even if the friction is reduced, or even if the friction between the tire and the slick tire is reduced by coating and impregnating wax and then scattering powder, it is as simple as above. It is possible to cause the car body to slip.

<Examples> Hereinafter, examples will be described in detail with reference to the accompanying drawings showing examples.

FIG. 1 is a diagram showing an example of a driving course, for example, an elliptical circular course with a total length L1 in the major axis direction of about 50 m, a total width L2 in the short axis direction of about 29 m, and a course width L3 of about 9 m. A buffer embankment 2 is provided around the inner and outer peripheries of the tire, in which old tires are piled up in several stages.

The road surface of the driving course 1 is finished with concrete, and the upper surface of the driving course 1 is covered with talc made of fine talc whose main components are SiO ₂ (silicon dioxide), MgO (magnesium oxide), etc. The powder 4 is uniformly scattered in a thin film form to form a smooth running road surface. Note that 3 in the figure is concrete mortar used to finish the road surface.

Figure 2 is a diagram showing an example of a go-kart, in which the front and rear wheel spacing L4 is about 1 m, and the left and right wheel spacing L5 is about 1 m.
It is a 0.8m small vehicle, and is a rear-wheel drive vehicle in which the rear axle 6 is driven by a small engine (displacement approximately 144 c.c.) mounted at the rear of the chassis, and the rear wheels 9A and 9B are driven. It has a four-wheel vehicle structure. The front wheels 8A, 8B and the rear wheel 9B are slick tires (tires with no block patterns such as protrusions or protrusions), which increase friction with the normal road surface and improve road holding. That's what I do. That is, the road holding of each of the above wheels during rain, snow, etc. is difficult due to the fact that water exists in a layer between the tires and the road surface.
very low. In addition, the rear wheels 9A are regular tires, and the tread pattern allows the water to be concentrated in the grooves, and the protruding parts are in direct contact with the road surface, resulting in fairly good road holding. . It should be noted that the rear wheels to which the above-mentioned normal tires are mounted are preferably located on the inner peripheral side with respect to the running course, so that appropriate slip can occur.

As shown in FIG. 2C, the chassis is equipped with a plastic body 10 having excellent cushioning properties and impact resistance.

That is, the go-kart 5 speeds up the speed on the slippery road surface by operating the handle 11, the accelerator (not shown), and the brake (not shown).
It is designed so that it can run freely at speeds of 30 to 40 km, and slips easily when cornering or braking while driving, almost unaffected by the driver's intentions.

Therefore, when the go-kart 5 is run on the above running course 1, all wheels except one driving wheel are slick tires, which have extremely low frictional resistance with the running road surface, and are suitable for use during snowfall. It will be running like this. In other words, if you press the accelerator fully and try to start suddenly, or if you try to corner by operating the steering wheel beyond a certain level,
When attempting to brake by operating the brake, etc.
The slip phenomenon easily occurs regardless of the driver's intention, so in order to restore the normal driving condition, in other words, to prevent the collapse of the vehicle body posture due to the slip, to quickly restore the vehicle, and to minimize the amount of slip. Students will be able to sufficiently acquire reflexive driving techniques that deal with slips in steering wheel operations (counter steering, etc.) and brake operations (brake operation amount, etc.) to prevent slippage. Note that it is also possible to cause the slip to occur as intended by the driver.

In addition, since the slip phenomenon occurs very easily and frequently, you can experience conditions that cannot be experienced on normal road surfaces, such as spinning the car body, and enjoy a sense of freedom, exhilaration, thrill, etc. can do.

FIG. 3 is a diagram showing another example of the running course, in which the road surface of the concrete mortar 3 is buffed to make the surface roughness smooth, and wax 12 is applied to the finished surface.
It is slightly impregnated with.

When the go-kart 5 having the configuration shown in FIG. 2 is run on the running course 1, since the frictional resistance between the slick tires and the slippery road surface is very small, the same phenomenon as in the embodiment described above occurs. can easily appear.

Furthermore, in each of the above embodiments, since the driving course is provided with buffer banks 2 on the outer and inner peripheries, even if the driver has not sufficiently acquired reflexive driving skills, It only collides with the buffer embankment 2, and there is no particular danger.

Note that the present invention is not limited to the above-mentioned embodiments. For example, as a running course, as shown in FIG. 4, wax may be applied to the finished surface of concrete mortar that has been buffed to have a smooth surface roughness. It is possible to use a material that has been slightly impregnated with talcum powder and then sprinkled with talc powder, or a material made of stainless steel plate with a polished surface.
In addition, various design changes can be made without changing the gist of the invention.

<Effects of the Invention> As described above, the present invention can easily cause a slip phenomenon almost unaffected by the driver's intention (of course, if the driver intends to do so), the slip phenomenon can be easily caused. It is said that it is possible to teach reflexive driving operations in response to phenomena, and in turn, it is possible to reflexively apply the acquired skills to the slips that occur during actual driving, and to control the vehicle body and prevent accidents. It has a unique effect.

Furthermore, when used for entertainment purposes, for example, it is possible to perform a car body spin, in which the car body rotates round and round, and there is a sense of freedom and exhilaration that allows you to do something that you would normally not be able to experience, and it produces an entertainment effect that allows you to fully enjoy the thrill.
