Abstract

PURPOSE:To improve the performance of travelling on an irregular ground by pivotably mounting plural rotating shoes at radial ends of a rotatable supporting member, and making the rotating shoes rockable through links and a central operating portion by an eccentric quantity adjusting member. CONSTITUTION:A radial supporting member 1 is rotatably supported about a cylindrical shaft 2, and it is connected through gears 3 and 4 to a motor 5. Plural rotating shoes 7 are pivotably mounted on horizontal shafts 6 at the radial ends of the supporting member 1. The rotating shoes 7 are also pivotably mounted by pins 9 to links 8. The links 8 are collected at a central portion, and are connected to a shaft portion 11 of a universal plate joint 10 on one side thereof. The other side of the universal plate joint 10 is connected through a spherical joint 12 to one end of a rod 13. The other end of the rod 13 is connected to an eccentric quantity adjusting member 14. When the universal plate joint 10 is operated by the eccentric quantity adjusting member 14 to thereby upwardly move a theoretical center P, a grounding surface of the rotating shoes 7 is oriented downwardly to enable the shoes to get over a step.

Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, there have been wheels of a special shape with a large number of rotation wheels arranged radially, and they have been evaluated simply as having interesting designs or as heavy wheels for agricultural work running on soft roads.

The purpose of this invention is to enable swinging of the conventional rotational fast wheels without fixing the legs. ls
! On the road, the position of the rotating shoes is changed so that the tread is oriented as if a person were walking; the purpose is to improve the ability to jump over steps.

Therefore, the gist of the present invention is that a large number of rotors having arc-shaped treads are arranged radially, these rotors are swingably supported by a horizontal axis, and are linked and connected to a central operating section. The central operation part has a structure that allows it to move vertically, horizontally, and vertically by means of a rigid eccentric adjustment body, and has a rotation mechanism.

Next, an example of the present invention will be described with reference to the drawings.The structure is such that a radial support 1 is rotatable around a cylindrical shaft 2, and is connected to a motor 5 via gears 3 and 4. Further, a rotatable shaft 7 is pivotally attached to a horizontal shaft 6 provided at the tip of the support 1, and is connected to a pin 9 through a link 8I. Links 8, 8-8... are bundled at the center and fitted onto the shaft portion 11C of the flexible plate member 10.

The opposite side of the flexible plate member 10 is connected to a lever bar 13 by a spherical joint 12, and is provided with a fixed eccentric i adjustment body 14 (such as two hydraulic cylinders).

The rotating shaft 7 has a circular arc road surface 71 and a flexible sponge 72.
It has a structure that absorbs vibrations from the road surface.
It also has a tread pattern.

As shown in Figure 3 (b), each rotation (7 is the lowest ground rotation (7) is a circular movement centered near the center of the bottom surface of the 0 rotation that draws a trace of the cycloid vL (also receives the tread surface). Since the force ? is slightly different from the direction of the tread's motion
and the force f2 that causes the user to try to slide parallel to the tread surface. (In case of suspension) When there is a step in the height of the axle, when rotating with a wheel-shaped circular arrangement as shown in Figure 3 (a), the tread faces forward, so there is no catch and the tread is received from the tread. The force component f1 acts to push the axle, and the force f2 acts directly upward, making it impossible to overstep.

However, when the eccentric adjustment body is operated to move the flexible plate member lO and move the theoretical concentration point P upward, the tread of the rotating shoe becomes slightly downward, and therefore? The component force f that tries to slide
2 decreases and becomes forward-facing, it becomes possible to catch and ride over differences in axle height. .

The difference in traversing performance when not waiting for driving force is shown in Figure 4. When the vehicle collides with a step one foot high during inertia running, the force f1, which is also received by rotation (also on a tread surface), is component element 3, which becomes running resistance. Component 4 tries to lift the rod body and [; Naru, 458th
Compared to (a), in (1)) and (0), the t4 component is thicker and the f3 component is smaller, so the latter has less front part and can step over obstacles without hesitation. . At this time, the treading force exerted by the rotation (on the tread surface) is 3rd (b)
As is clear from C: It has the same effect as if the diameter of the wheels were many times larger, and it is able to overcome uneven terrain and deep snow.

In addition, since the front and rear treads of the rotation are directed downward, there is very little chance of sinking into soft, sandy or muddy ground.

Furthermore, eccentricity! l: Adjustment body C; First bury the flexible plate member 1o! It is possible to not only move the center point P upward, but also to move it forward, so that the tread of the lowest rotating foot is directed slightly backward. When giving a drive to the rotation, the force to push the ground backward increases.

Therefore, the driving force and gravitational force on sandy or muddy ground are significantly increased, allowing the car to run powerfully even on soft ground.Also, even if it falls into a deep hole, the force of the rotating blade will sweep the earth and sand backwards, and the reaction force will be used. Case 8c: Escapes.

In the rotating mechanism of the present invention, a large number of rotating shoes each having an arcuate path 1ffl are arranged radially. , and the central operating section is configured to be movable vertically and horizontally by means of a fixed eccentricity adjusting body.
When traveling on uneven ground or over steps, it is possible to increase the overstepping force by operating the eccentric fk articulated body to shift the theoretical concentration point upward or forward, changing the attitude of the rotating wheel. In addition, on soft ground such as sand blasts, the front and rear treads of the lowest rotation can be directed downwards, so there is less sinking to the ground, and the eccentricity adjustment mechanism Return C2 to its original state, make the amount of eccentricity zero, and rotate the wheel shape C;
Arranging the wheels in a circular manner (C) has the advantage of significantly reducing running resistance on paved roads.
