Description

[Detailed Description of the Invention] The present invention relates to the stable running of automobiles using rubber tires on frozen roads. Metal dust causes rust in the human lungs, and on top of that, the number of cars is increasing year by year, and road repair costs amount to 1 billion to 3 billion yen per year in one city. There are currently no pins, and it is hoped that the pins will be completely abolished. In order to eliminate the drawbacks of current tires as described above, the present invention aims to improve the user's preferred form (handling convenience), and to replace major equipment such as the original tank, compressor, motor, etc. with other equipment. One embodiment of the present invention will be explained with reference to the drawings.As shown in Fig. 1, the inner surface of the contact area of the tire is made thicker to remove the 1), and the wheel is molded to form a ring-shaped rail (2). In this example, eight air branch pipes (5) arranged radially are formed.
) communicates with the air hole (7) in the wheel axle (6), and the other end of this air branch pipe (5) communicates with each tire, allowing for instantaneous air inflow and outflow of the tire. The grease in the grease casing (8) is supplied to the wheel metal fitting (4), which is the wheel rotating contact surface, and the wheel axle contact surface (9), and a built-in leaf spring always presses both grease surfaces, creating an airtight seal. is maintained, and the air in the air hole (7) in the wheel axle (6) is

The engine power source (35) is connected.

Since the present invention is configured as described above, changing tire air pressure is controlled by the driver's seat lower limit pressure setting device (33) shown in FIG.
is set to 1.5 kg/cm2, and the intermediate limit pressure for maintaining reduced pressure when changing tires is similarly set using the intermediate pressure setting device (34
) to 2 kg/cm2, and when the road is frozen or snowy, in the driver's seat, after turning on the engine key switch (32) as shown in Figure 2, turn on the driver's manual switch (29).

When the weight is below 5kg/cm2, the 6 contacts (18"
) is cut, and accordingly, the lower limit set pressure is maintained, and the variable tire (36) is maintained together with the supporting pressure of the fillet (1) in FIG.

Also, when returning to regular tires after getting off a frozen or snowy road,

(On the safe side keeping the driving tire condition at that time).

In addition, the present invention has a function to eliminate most of the accidents that occur during driving when ``I noticed and stepped on the brake, but I couldn't stop in time''. (within 2), the A microswitch (26) to the B microswitch (26) in Fig. 2

Within seconds, the solenoid valve (19) in Figure 1 closes, and at the same time, the scavenging solenoid valve (20) opens the scavenging port (21), that is, the tire changes (36), (tire contact area but,
The braking distance is more than four times longer than that of a spike pin, and as a result, during normal driving, it has the rugged feeling of a straight line, and there is no need for flat tires that waste running power, resulting in a comfortable ride. It is possible to use 82% more tires, which reduces tire noise, and makes the body support springs softer.) Since the braking distance is shortened, it is effective to use an anti-lock brake system that reduces shock when stopping. becomes. and,
When the brake pedal is released, the B microswitch (26') in Fig. 2 is turned off, and then the A microswitch (26') is turned off.
6) breaks and becomes a regular tire, and most of the time when driving on a regular tire is a series of normal braking, so only in case of an emergency,
Since the braking is sudden, the feeling of normal braking that is normally used is not lost.

In addition, the present invention provides a solution for "if you get a flat tire" while driving on a highway.
For a moment, everyone felt anxious. When air leaks from the tire at the time of a puncture, the air is automatically transferred to the air branch pipe (5).
All tires are refilled more quickly and continue to run with the same pressure.

Further, in the present invention, the tire pressure can be switched between 5 kg/cm 2 and 4 kg/cm 2 using an upper limit pressure setting device (37) in order to reduce the roughness of the vehicle body due to the loaded weight and road conditions.

As mentioned above, the present invention is based on the factor of increasing tire frictional resistance, so it is effective to use a tilting device (57-226417) with little change in ground camber, and since this device is a four-wheel drive, Even on uneven roads, the wheel rotational force
The somewhat long wheel axle is used as a particle to tilt the car body and pull up the steering wheel, so it is easy to operate the steering wheel, just like the four-frame model that came before.

In addition, the present invention has two lines of piping, one on the left side and one on the right side of the center of the vehicle body, that is, the left and right pipes (12) connect the left front wheel and the rear wheel with the main stream pipe (13), and a connecting pipe (14) is attached. The left side system is used as the left side system, and the right side system is used as a contrast, and the joint pipes (14) of both systems are connected to the common main tank (15). In the following cases, at all steering angles (left front wheel, negative 40°, right front wheel, rightward 40°) of 0° to 40°, the mechanical inclination is 0° to 1.5° stepless. = "When the vehicle speed is 40 km/h to 60 km/h and the steering angle is within 12 degrees, it is the same as A, and the steering angle is 12 degrees.
In the above, horizontal restoration by air suspension is added." C = "Even if the vehicle speed is 60 km/h or more, if the steering angle is within 12 degrees, it is the same as in A, and if the steering angle is 12 degrees or more, the vehicle body turns inside. In other words, in order to prevent the air suspension from swaying from side to side due to anti-rolling, the air suspension should stop restoring the vehicle horizontally. The mechanical inclination is stepless and each part is divided little by little, allowing it to work smoothly.

In addition, in the present invention, when the front two wheels are floating in the air on a concave road, the rear two wheels are pressed against the ground surface, so a pressure difference occurs between the front wheels and the rear wheels, and air flows from the rear wheels to the front wheels. As the flow flows in, the pressure resistance of the front two wheels increases, which reduces the sinking of the front part of the car body when it falls to the ground. flows toward the rear wheels, reducing the springing force of the front wheels, that is, suppressing the pitching of the front of the vehicle body, and the same is true for the rear wheels, preventing vehicle body resonance.

Horizontal wheel system (60-18
9418), since the high pressure rubber tube (11) of the present invention is flexible, it can be applied to a variable tire device, that is, when the spin prevention is in the same phase, "front wheel 12°, rear wheel 1.4°", During normal driving with the front wheels turning 40° and the rear wheels turning 34.6° to the right when the vehicle is out of phase, its turning performance is excellent, and it can be safely parked in the garage by turning around and reversing. A worm wheel for preventing spin is aligned and meshed with the worm for steering the rear wheels of the arriving vehicle on the same plane as the worm wheel for steering of the coming vehicle, and the worm wheel for preventing spin is
With the shaft at a fixed position, a groove is dug in the flat surface of the groove, and from the center line of the groove, the groove extends diagonally backward to the left (with respect to the direction of vehicle travel) and diagonally forward to the right, and is further bent and reflected. A shaft that slides in this groove and a shaft of a steering worm wheel (sliding with a guide in the longitudinal direction of the vehicle body) extend in the direction of the shaft, and a groove extends in an arc centered on the shaft, forming both groove ends. Connecting rod rod (
Both wheels slide in the axial direction with guides),
In other words, the slanted grooves work to prevent in-phase and anti-phase spins, and the arcuate grooves at both ends keep the shaft of the worm wheel for steering the rear wheels in a fixed position without sliding. When driving sideways and parking in a row on the side of the road, it is preferable to raise the car body horizontally by 1.5 degrees because the center of the road is generally high, that is, the cross section is arched. It becomes parking.

As mentioned above, while the present invention has the importance of "stopping before it hits," it is also a device for adjusting the roughness during regular use.
In addition, in terms of safety, stability of passengers and cargo, and comfort, the slope makes it more comfortable to ride on an airplane, and it also uses liquid nitrogen superconductivity to make driving feel like aircraft control. This is a variable machine (59-090286) that does not stall (because the knock sensor reduces the current in the transmission), and the operation is the same on both downhill and flat roads, so the brakes are easy to operate. This engine, which can be combined with
The four elements of the car (turning and stopping) function to provide an even greater sense of riding and control.
