Abstract

PURPOSE:To prevent both the slipping of a tire and the damage of a road surface by providing a spike in the inside of each groove formed on the ground- contacting surface of the tire so as to be oscillatable via a shaft and bearings, and so as to be retractable to the groove via a support plate. CONSTITUTION:On the ground-contacting surface 9 of a tire, grooves 10 for preventing slipping on a snowless road surface, and also deeper grooves 1 are formed. And in the bottom part 2 of the groove 1, a shaft 4 of a spike 3 is oscillatably arranged via bearings 5. In the middle part of the groove 1, a support plate 6 for supporting the middle part of the spike 3 to prevent unnecessary idle movement is arranged, and also a magnetic attracting part 8 is arranged in the part opposite to the support plate 6. And as the tire slips, the support plate 6 is detached from the magnetic attracting part 8, and the spike 3 is projected from the inside of the groove 1 to the outside of the ground-contacting surface 9. Thus, the spike 3 is made to bit into an icy,. snowy road surface or the like for preventing the slipping of the tire.

[Detailed Description of the Invention] A. What is a seesaw spike? It is a general name for a device whose main parts include a shell (Fig. 1-7), a shaft (Fig. 1-4), a spike (Fig. 1-1), etc. The main improvement of the seesaw spike, in which the right side is the forward direction of the car and the left side is the backward direction, is that the individual seesaw spikes are connected to each other so that they do not move (Figures 1-12 and 8). 2-12 and 8
) The shaft is attached to the shell, and there is a skirt made of soft material on the underside of the spike (Figure 1-6) that fits into the shaft hole of the spike (Figure 2-18).
) The above three points are (Figure 1-A) The posture of spikes during forward driving on a snow-covered road The contact surface of a tire with forward driving (Figure 1-1 11)
20) slips backwards. From a relative point of view, the snow scrapes the contact surface and rushes forward. The snow pushes the skirt of the bottom of the spikes deeply forward. The spikes see-saw and tilt backwards. The rear wing (Fig. 1-3) plunges into the snow and tries to rotate further.On the other hand, the front wing (Fig. 1-2) that goes up hits the stopper (Fig. 1-11), where the spike stops rotating and goes into the snow. When the front wing is ready for spiking, the front wing pushes the stopper with a strong force, so the entire seesaw spike receives a force that tries to rotate it in the opposite direction of the clock hands.If this is installed alone, there is a point where it will fall off.
To prevent this from happening, connect piano wires (Figure 1-12) (Figure 2-12) between the seesaw spike shells (Figure 1-7), shell wings (Figure 1-8), etc. Furthermore, when each shell wing is fastened at the front and back of each other (Figure 1-8), a force is applied to all the seesaw spikes to rotate them in the same direction, so the rear shell wing of the front seesaw spike is pushed down and rearward. The front shell wings of the seesaw spike are pulled upward by the same force, so they cancel each other out and become stable.The next step is to attach the shaft to the shell, which strengthens the shell and makes it easier to attach and detach the shaft. (Fig. 2-A) When relocating the shaft, create an axial hole (Fig. 2-8) in the spike.To strengthen the spike, make it thicker upwards.Horizontal position, Forward position, Reverse position of the shaft. Spring stops that combine the shaft with the shaft hole (Figures 2-11 and 22) and spring stops that are installed in three locations on the inner shell wall and the side of the shaft (Figure 1-1)
13iro. 14 iro. 15 iro) (Figure 2-13 iro.1
4iro. Next, the third item is the skirt, which is made of a soft material such as rubber or plastic, and its underside is made so that it is almost at the same level as the tire contact surface (Figure 1- 25)
As a result, when a skid occurs on the snow, this skirt receives the flow force of the snow and tilts the spike, controlling the initial movement of spiking. The rear wing, which had been spiking on the snow while driving forward, slid forward on the snow, fell down and approached the horizontal position, and then the sprinkling stop was activated and the plane remained in a horizontal position, and the skirt continued to touch the snow. It is pushed backwards, the spike leans forward, the front wing plunges into the snow, and it stands up.The rear wing hits the stopper and at the same time the spring stop is applied, causing the vehicle to brake and move backward.Figure 1-C While driving, the vehicle is facing a snow-free road. When this occurs, immediately apply the engine brake.Then, the number of rotations of the tires decreases compared to the inertial speed of the vehicle body, so a force that pushes the vehicle forward on the ground is applied.The rear wing, which had been upright, is pushed forward and the spikes become horizontal. When you reach a snow-free road while braking, step on the accelerator to speed up.

When this happens, the rotation of the tires becomes faster than the inertial speed of the vehicle body, and a tensile force is exerted on the ground contact surface.Therefore, the front wing, which was standing upright, falls down as if being pulled down, and the spikes become horizontal.After that, there is no snow. If there is no slipping on the road, the spikes will remain at a flat level, in other words, they will run as normal tires. Description of the so-called cat's claw snow tire The shell (Fig. 5-1) (Fig. 6-1) is preferably made of something like carbon fiber. The inner cavity of the shell stores the spikes (Fig. 5-7) (Fig. 6-7) and serves to support the external forces received when the spikes protrude. Grooves are provided on the left and right side walls to guide the spikes. Also, one end of the shell is called a groove (dotted line in Figure 5-2) (Figure 6-2) and has a gate that opens toward the tire's contact surface. This is the gate (Figure 5-
3) The spike called (Fig. 6-3) has a strong cylinder that protrudes left and right at its upper end. Fit it into the groove. Therefore, the lower end (tip) of the spike points toward the gate (Fig. 5-A. The C spike is a permanent magnet made of steel, with the leading end being the south pole and the long axis of the back of the shell having the tip as the north pole. Place an electromagnet (Figure 5-4) on the midline.The electromagnet is a coil wound around an iron core, and both ends enter the inner cavity from the front and back of the shell and are placed in contact with the spikes (Figure 5-5). The electromagnet's coil is connected to conductors that are separated into two systems near each end.
Each of the conductor wires follows a different system and connects to separate power receiving overhead wires (Figure 7-C) Power receiving overhead wires (9.13.) The two power receiving overhead wires are half exposed on the side of the tire and form concentric circles with half diameters of two sizes, large and small. Meanwhile, the cord led from the switch installed in the driver's seat is attached to the distal part of the suspension, that is, the relay attached to the part that is always kept in an inseparable state (Fig. 7-A). (Figure 7-20) It connects to the tire power receiving wire (Figure 7-B.C.) like a pantograph on a train.
-9.13) This tactile movement is based on a switch command from the driver's seat and an electronic command to supplement it.When approaching a snow-covered road, the driver must switch the spike protruding switch. Pantograph A (Fig. 7-8) approaches the tire and contacts power receiving overhead line A (Fig. 7-9), and then energizes.Electricity passes through A system (Fig. 7-10) to coil A end (Fig. 5-9). 11) Inflow from electromagnet A end (Figure 7-11)
Figure 5-11) (Figure 7-11) becomes the magnetic pole of S, which repels the S pole of the guide shaft of the spike, and the S pole of the spike follows the guide groove to the B end in the opposite direction (Figure 5-15). Run towards N at the B end
It collides with the pole and becomes magnetized.At the same time, the north pole of the spike light repels the north pole of the electromagnet and plunges into the snow, starting to act as a slip stopper. The support for spiking is to hold down the spike part at the end of the guide groove and use the rubber of the tire crown as a fulcrum to support the weight of slipping on the snow.Therefore, when the spiking position is completed, the power is turned off and the pantograph is turned off. Cat's claw spikes can be spaced apart. They are neither used for forward driving nor braking for backward movement. They are all the same shape. However, when assembled into a tire, they just need to be arranged in opposite directions. That way, they can be used for forward movement or reverse movement. (Figure 5-B.D) (Figure 8-18.19) The spikes all stick out when the A line is energized.While driving on snow, even if you repeat driving and braking, they will remain in their respective positions. When the driver reaches a snow-free road where the tires will exert their power, the driver turns on the spike retraction switch. Pantograph B (Figure 7-12) approaches the tires and contacts power receiving overhead wire B (Figure 7-13). Then, the current is applied. The current passes through the B system line and enters the coil from the coil B end, that is, the electromagnet B end (Fig. 5-15) (Fig. 7-15). The B end generates an S pole magnetic field line. The S pole of the spike head is repelled. , it is attracted to the S pole of the A end and magnetically attached to it.The N pole of the spike light end is magnetically attached to the S pole of the electromagnetic B end, and the retraction is completed.When the state of retraction magnetization is completed, the power supply is stopped and the pantograph is turned off. Even if B is separated, it will remain in the retracted state, that is, it will run as a normal tire.As a structural precaution, the spikes when retracted are almost parallel to the tire contact surface, and the guide groove is at the gate. In the case of a four-wheel drive vehicle, it would be fine to have the same number for forward movement and braking, but in the case of a two-wheel drive, the driven wheel is only used for braking, so the driving You will have to increase the proportion of the wheels for forward movement.
