Abstract

The present invention relates to a wheel which is directly based on a suspension device that absorbs a shock applied to a body such as a vehicle due to an irregularity of a road or a feature when a vehicle is moved. Although it has not been developed, modern wheels (tires) made of rubber and air, which are the most rational method together with suspension devices, are used to absorb various shocks transmitted to the main body when moving various devices such as automobiles are invented and used. In addition, the track wheel was also invented and used universally in order to use it smoothly in the bad conditions (snow, ice, sand, mud, etc.) which is a weak point of the circular wheel. However, this is also considered to have limitations, and by devising and using a shock absorbing device only on a wheel separate from a suspension device such as a vehicle, it is possible to improve the problems of wheels or track wheels using air. Pneumatic wheels can be formed as punctures and track wheels as shock absorbing wheels without extra suspension. Equipped with a highly elastic spring with absorbing shocks transmitted from the wheel of the vehicle, etc. from the wheel. In addition, the wheel barrel is a spring together with a non-pneumatic tire to function as a track wheel, and interacts with the springs mounted in the middle so that the circular wheel is widened (crushed) to the load of the equipment, etc. Not only a lot of friction is formed but also shock absorption function

In addition, the spring structure that is mounted in the middle is also made of several structures to cope with the left and right or other impacts on the wheel itself by placing more than one row, and because of the severe torsion or bending in the spring structure during operation, the spring elasticity can be lost. The present invention consists of those that promote safety during operation by mounting a stop bar that prevents twisting or bending more than one value.

According to the present invention, the wheel wheels, such as automobiles, are equipped with wheel springs having various resilience, such as different stresses and tensions. As the wheel itself is absorbed, the equipment with the suspension device further improves the shock absorption, etc. The equipment without the suspension device is configured to absorb the shock transmitted during driving with the present invention alone, and also the M of (Fig. 2). Like the invention of the type, the spring barrel and airless tires are mounted and deformed by the load of the equipment (FIG. 4).

As described above, the conventional wheel is devised by the suspension device, the air tire and the track because there is no such method, and the tire which does not inject air is produced, but the shock absorbing power from the ground is insufficient. In addition, track wheels widely used in military tanks, construction equipment and the like are effectively used. However, in production, there are problems such as the complexity of the structure and the cost of absorbing shock. In order to solve this drawback, the M-type wheels of Fig. 2 are also arranged to have several (6 to 10) to overcome the disadvantages of the track wheel which is currently a problem when using the present invention has been devised to devise the present invention .

As described above, when manufacturing the spring wheel wheels, it is not possible to design and produce the existing equipment system in order to graf on the various mobile equipment (automobiles, agricultural machines, tracked vehicles, etc.) currently being produced. As there is a great variety of existing equipments, there are many types and types of existing equipments, so that the characteristics of the current equipments are carefully examined, taking into consideration the load and structure of the equipments as much as possible. Since stability promotion is the key, it should be able to sufficiently offset the various loads transmitted to the wheels, and also ensure the maximum speed of the vehicle equipped with the present invention.

Thus, the inventors have carried out various experiments by mounting the present invention on a limited vehicle, and are still going on.

To overcome all of the above, a high degree of mechanical engineering is required.

In addition, there are aspects that are insufficient to produce with the existing production equipment, and the development of a variety of production equipment is followed.

In the present invention, unlike the conventional wheels, the barrel that surrounds the tire with a barrel for mounting a spring of a certain type on the portion connected to the drive shaft and the (SC O type) plate spring or spring of various types therebetween It is composed of leaf springs and springs with high elasticity and high resilience to support the load of moving means (vehicles, etc.) using this wheel, as well as absorbing the shock generated on the road or the ground by using the stress or tension of the spring. It can be manufactured and used according to the load of the back. It can be used by integrating the tire wheel with the air that is being used now, and the tire without the air can absorb the load or the impact instead of the air. Is produced. When manufacturing the mixture with the air-injected wheels in the above it can significantly increase the shock absorption rate delivered to the ground, and also put the joints or convenience devices of various forms on the wheels of the present invention more smoothly the impact generated on the road or the ground during operation Can be removed.

The above and the spring is replaced with a slightly deformed wheel, that is, the barrel covering the tire discussed above is made of a wheel that performs a variety of functions in the production.

The greatest advantage of the present invention is that the wheel itself has a large ground plane due to the equipment load of the vehicle. The width adjustment of the width of the ground plane is carried out by carefully calculating the elasticity of the wheel spring between the spring barrel and the drive shaft barrel and the spring barrel with the load of the machine in mind.

According to the data experimented by the present inventors, it can be seen that the characteristics of the wheel have a small ground plane at first when a load is generated, but it is proportional to a certain level later. Widening means that the wheel has a great friction when moving the equipment. Accordingly, the wheel can move smoothly on the road or the ground (snow, ice, sand, mud, etc.) that conditions are not good at the time of driving, and can also be equipped with Eisen, etc. on the wheel as an auxiliary equipment can double the capacity.

The above-mentioned Eisen is also equipped with the advantage that the air can not be injected into the tire easily removable structure.

In addition, a stop bar is placed between the drive shaft barrel and the tire barrel or the wheel spring itself to prevent sudden shock absorption when the vehicle moves, and to maintain the proper elasticity of the spring. Do it.

In addition, the theory discussed above is a kind of plastic P. It can also be widely used for wheels of vehicles with low loads (such as strollers) using C (POLY CABONATE) or coil springs.

Hereinafter, described in detail by the accompanying drawings as follows.

In order to effectively use the shock-absorbing wheel according to the present invention, such as a conventional mobile equipment, the high-elastic spring and the structure having a variety of forms and the structure is a stop bar or spring joint, spring barrel, Eisen, etc. to effectively control or improve the function It relates to a shock absorbing wheel, characterized in that consisting of.

In order to carry out the object of the present invention as described above, the spring wheel barrel of the above-described type having a high elasticity, such as the S-type wheel spring ① C-type wheel spring ② (O) wheel spring ⑥ (Fig. 2) ③ When the shock occurs in the ground when moving and installed as shown in (Fig. 5) between the spring wheel drive shaft ⑤, the spring ② is stressed and tensioned as shown in (Fig. 3), and the center of the spring wheel drive shaft ⑤ is deformed from C to L to shock. Absorb.

After that, it returns to the original position as shown in (Fig. 1). These phenomena occur repeatedly, depending on the road or ground conditions. At this time, the spring wheel barrel ③ is made of non-elastic metal and moves up, down, left and right about the drive shaft ⑤.

In order to smoothly implement this condition, install a spring wheel joint bundle as shown in Fig. 6 as shown in the figure. In addition, if the wheel spring ② is placed in a pair as shown in Fig. 8 (Fig. 8), when the topography of the road or foreign matter (stones) occurs on the road as shown in Fig. 8 (B), the wheel spring on the left of the wheel Bends more than a spring.

In addition, the tire of ⑧ is also raised to the ground as shown by the left arrow. At this time, to prevent the wheel spring from twisting, ⑮ spring wheel joint acts to offset it. In addition, the spring wheel joint of Fig. 7 acts to the left and right as shown in the figure to cancel the shock transmitted sharply. All of this happens instantaneously by the speed of the vehicle.

In order to prevent the extreme bending of the wheel spring of ② when the above things proceed, install the stop bar of ⑬ to keep the spring elasticity continuously.

Spring deflection beyond the limit does not maintain adequate elasticity.

The stop bar of can also be arranged directly on the spring as shown in (Fig. 12) (Fig. 13) (Fig. 14), or in the form of A, B.C of (Fig. 15).

(Fig. 9) is a picture of the spring barrel ⑦ is the spring weight ⑦ horizontal or vertical cavity for the purpose of smoothing the function of the M-type wheels (Fig. 4) when the load on each wheel is small due to the weight of the vehicle when manufacturing the wheel (Pull off) to produce.

As described above, the wheels of the vehicle having a low weight cannot have a thin spring barrel ⑦ at the time of manufacture due to the small load of each. When manufactured in this way, a problem occurs in safety or durability, so it is used to guarantee a constant thickness.

(Fig. 10) relates to the C-type wheel spring of (Fig. 1) and should be maintained in the direction as shown when mounted on this wheel. This is because the spring wheel drive shaft ⑤ moves clockwise as shown in the figure. At this time, the wheel spring ② moves like the arrow to the upper side and the lower side to the left side as shown in the picture. In this state, the vehicle must start and move down slightly. However, if the installation is reversed, the vehicle lifts up and moves when the vehicle starts. The occurrence of the above is a result obtained by directly mounting the wheel of the present invention to a vehicle.

Vehicles or mobile devices equipped with shock absorbing wheels having the structure as described above can be more convenient and improved comfort due to the improved shock absorber when moving, and also reduces the accidents caused by punctures without the need to inject air In the case of the M-type (Fig. 2) can be used to replace the orbital wheels used in construction equipment or military equipment by mounting a number of M-shaped wheels, and the cost is also expected to be cheap. In particular, since the M-type wheels have a large friction force, they can be widely used for other equipment that requires them, and the mobile equipment without the suspension device of the shock absorbing wheels such as the S-type C (Fig. 2) and O-type (Fig. 1) also performs. In addition, it is possible to produce inexpensive mobile equipment by helping to improve.
