Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gasoline engine car that runs using a small-sized toy Kallin engine as a power source, and particularly relates to a gasoline engine car that is connected to a flywheel on the output shaft side of the small-sized toy gasoline engine. Regarding what has been made possible.

[Technical Issues] Toy gasoline engine cars, which run using a gasoline engine as their power source, have been widely popular not only among children but also among adults because they have a sense of speed and drive realistically. be.

However, conventional gasoline engine cars were so-called poppies, and the engine and body of the cars were not suitable for children to easily play with, and a solution to this problem was desired.

[Means for Solving Problems] As a means for solving the problem described in 1-1, a gasoline engine car according to the present invention links a gasoline engine for a small toy with a city axis, drives the city axis to rotate, and runs as described in L. A flywheel is installed on the output shaft side of a gasoline engine for small toys.
The engine rotation and flywheel rotation are linked, and the purpose is to make it easy for even children to handle, and to realize stable and realistic running even on rough roads. .

[Example] Hereinafter, an example of the present invention will be described based on the drawings. 1st
The figure is an overall perspective view showing a gasoline engine car according to an embodiment of the present invention, Figure 2 is a perspective view of the drive section, and Figure 3 is:
jS1 is a side sectional view, and FIG. 4 is a rear sectional view of FIG. 1.

In the figure, a gasoline engine car 1 has a gasoline engine 2 for a small toy, a flywheel 3, a tooth 1P group 4, etc. mounted on a chassis 5L, and a body 6 imitating the shape of a car is mounted on this L.
It will be covered with

The gasoline engine 2 for the hand-shaped toy (hereinafter simply referred to as the engine), like a general gasoline engine, sucks in a mixture of gasoline fuel and air, burns it to generate power, and rotates the output shaft 2a. It is something that is driven.

The flywheel 3 is attached to the output shaft 2a and is rotationally driven by the power of the engine 2.

This flywheel 3 exerts a gyroscopic effect when driven to rotate and maintains the vehicle body in a stable state.
Considering the size and overall weight (j method, ton j11, etc.), as an example when the total length is less than 20 cm, the diameter is set to 5.
An excellent flywheel effect can be obtained by setting the l−1 ton jl￥ of 0 mm or more to 60 g or more, and setting the rotation speed north of 8000 r, p, m.

On the other hand, the gear group 4 includes a gear 7 provided on the output shaft 2a, an intermediate gear 8 supported on the shaft 8a, an intermediate gear 9 supported on the support 9a, and a crown gear 12 supported on the lO1 rear axle 11. be done. These gears sequentially mesh to transmit power, and the power of the output shaft 2a is decelerated to the rear axle 11.
drive the rotation.

As shown in FIG. 4, a crown gear 12 is loosely fitted onto the rear axle 11, and a sprocket 13 is fixedly attached thereto. Each of these has clutch parts 12a and 13a, which are pressed against each other by a spring 14 and are in mesh with each other.
Normally, power from the engine 2 is transmitted to the rear axle 11. When a load is applied to the rear axle ll side, the clutch portion 12a,
Since the crown gear 13a slips, the crown gear 12 rotates idly, and the engine 2 and the gear group 4 are not damaged.

The sprocket 13 is connected to the sprocket 17 of the front axle 16 by a chain bell i5, and when the rear axle 11 is driven, the front axle 16 is also driven at the same time.

That is, the gasoline engine car 1 rotates the front wheels 18 and the rear wheels 19 to run in four-wheel drive.

Next, the starting device for the engine 2 will be explained.

A gear 20 is meshed with a gear 7 provided on the output shaft 2a, and is supported in a long hole 21a of a frame 21. Further, the frame body 21 supports three auxiliary rollers 22 at a certain distance from the gear 20. These are long holes 21
Three of them are provided in the longitudinal axis direction of "a" and the "motor line" to assist the meshing of the starter 23, which will be described later, with the gear 20.

As shown in FIG. 2, the starter 23 has a rack-shaped (j123a) formed on the - side of the rod-shaped main body, and a grip portion 23b is attached to one end.When starting the engine 2, the starter 23 is Insert between gear 20 and auxiliary roller 22, and gear 20 and 1i23a match 111ii+IE
If the starter 23 is pulled in the direction of the arrow in the figure, the output shaft 2a can be rotationally driven. Note that when the starter 23 is inserted between the gear 20 and the auxiliary roller 22, the gear 20 is inserted into the elongated hole 21.
Since it moves toward the front in Fig. 2 along line a, tooth 23b and gear 2
0 becomes disengaged, making it easier to insert.

In the figure, reference numeral 24 denotes a fuel tank, which stores gasoline fuel therein so that the gasoline fuel can be fed into the engine 2 through a pipe 24a. Reference numeral 25 denotes a power plug, which is used to ignite the cylinder of the engine 2 at the time of starting by connecting a power plug (not shown) to the power plug.

Next, the operation of the gasoline engine car 1 will be explained.

First, the battery is connected to the power plug 25, and as shown in FIG. 2, the starter 23 is inserted between the gear 20 and the auxiliary roller 22 from the tip end. Then gear 20 becomes
It is pushed along the elongated hole 21a of the frame 21 while engaging with 123a of the starter 23, and is urged to enter the starter 23 while disengaging from the gear 7 and rotating idly. When the starter 23 is inserted to the vicinity of the base, hold the grip 1 part 23b and strongly pull the starter 23 toward you (in the direction of the arrow in the figure).

Then, the gear 20 moves along the elongated hole 21a while maintaining meshing with the gear 1i23a, engages with the gear 7, transmits the power of the starter 23, and rotates the output shaft 2a.

The engine 2 explodes and burns the gasoline fuel taken in from the fuel tank 24 to rotate the output shaft 2a, and the flywheel 3 also rotates at high speed accordingly. In addition, output shaft 2
The rotational driving force of a is appropriately decelerated by the gear group 4 and transmitted to the front wheels 18 and rear wheels 19 as described above, thereby driving both wheels.

In this way, the gasoline engine car 1 has a flywheel 3
The vehicle runs on all four wheels at an appropriate speed while rotating at high speed. When the flywheel 3 is driven to rotate at high speed, it exhibits a gyroscopic effect and attempts to maintain the output shaft 2a, which is the rotation axis, in a constant state yE.

For this reason, the gasoline engine car attempts to maintain a constant state against the external force exerted by uneven road surfaces, so that the car body does not get blown away and runs in a stable state. Furthermore, even if it collides with a wall or the like, due to the gyroscopic effect, it will be blown away, stabilize its posture, easily change direction, land, and run stably in the direction it landed.

[Effects of the Invention] As explained above, the gasoline engine car of the present invention has the following advantages:
A flywheel is installed on the output shaft side of the gasoline engine,
By linking the rotation of the engine and the rotation of the flywheel, the flywheel exhibits a gyro effect,
This allows gasoline engine cars to run stably even on rough roads. Therefore, since the vehicle runs more realistically than before, it has the effect of increasing the player's interest.

In addition, this gasoline engine car is small and has a simple structure, so even children of younger age groups can easily handle it.
