Abstract

PURPOSE:To alter the whole tread form consisting of a tread of each rotator to both step and circular forms as well as to aim at improvement in traveling performance by setting up a lot of rotary feet with a circular tread each in a circle at regular intervals, and altering a position of each rotator by a turning control body. CONSTITUTION:A lot of rotary feet 1 with a circular tread 11 each are set up in a circle at regular intervals. And, each rotary foot 1 is rotatably supported on each horizontal shaft 2 of respective drivers 21. And, an end of each rotary foot 1 is connected to a turning control body 4 via each connecting rod 3. In addition, the turning control body 4 is rotatably set up concentrically with the turning center of each rotary foot 1. Thereby, at the time of traveling on a snow-clad ground or an uneven ground, the tread 11 of each rotary foot 1 is tilted to a virtual circumferential surface with the specified angle, thus travelability is improved. On the other hand, at the time of traveling on a pavement, the tread 11 of each rotary foot 1 is made to go along the virtual circumferential surface, thus smooth running is secured.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating leg wheel having a split tire structure.

Conventional wheels were suitable for driving on hard roads, but they were not suitable for driving on snowy, muddy, sandy, etc. The purpose of the invention is to develop a rotary leg ML that is capable of running under these culm conditions and is comfortable to drive on paved roads.
It consists in offering compassion.

Therefore, the gist of the present invention is that a large number of rotating feet each having an arcuate tread surface are circularly arranged at regular intervals, and each rotating foot is rotatably supported about the horizontal axis of the driving body. Further, the end thereof is connected to a swing operating body via a connecting rod, and the swing operating body is located in a rotating leg foot ring which is arranged to be rotatable concentrically with the pivot center of the rotating leg. .

Next, the details of the rotary foot NL wheel of the present invention will be described with reference to drawings. Fig. 1 shows the state of the rotary foot wheel while running on uneven ground, where 1 is the rotary foot, 11 is its circular tread, and 12 is a spike. (hidden), 13 is a pin.

Reference numeral 2 denotes a horizontal shaft which rotatably supports the rotary foot 1. 3 is a connecting rod which is connected to the pin 13 and to the pin 40 of the swing operating body 4.

The turning operation body 4 has a concentric shaft 41 coinciding with the turning center of the rotating leg 1.

A spline 42 is formed in the deep part of the glaze 41 and the piston 4
One end of 3 is included. A cam f! is located near the center of the piston 43. 1144 and is engaged with the diagonal cam hole 45. Furthermore, the piston 43 is started from the cylinder 461.

21 is a 0-gen expulsion body with a radiation station, 9, gender 22,
-IITIII of the shaft 22; the diagonal cam hole 45 is formed, and the transmission member 23 is mounted. The nuclear toughening member blades are toughened by the prime mover 24.

When the input is input to the cylinder 46 shown in FIG. The connecting rod 3 is pushed to rotate the rotary foot 1 around the horizontal axis 2 to change its attitude.

Figure 1f13 shows the circular tread 1 of the rotating foot 1 in this way.
1 is aligned so that the overall outline is a circular wheel, and when driving on a hard paved road, you can run comfortably in this state without vertical wR movement.e I ran on a paved road. After that, if you come to a snowy area Φ sandy ground (ground, uneven ground, muddy ground, etc.), as shown in Fig. 1, you can rotate the rotating feet again, control the attitude of the treads 11 all at once, and change the overall shape into steps. , improves treadability and raises the height of the green to prevent pus from being rubbed.

In the rotating foot ring of the present invention, a large number of rotating feet each having an arc-shaped tread surface are arranged circularly at equal intervals, and each rotating foot lx N )
! It is rotatably supported by nine horizontal shafts, and its ends are connected to a swing operating body via a connecting rod, and the swing operating body is arranged so as to be rotatable concentrically with the center of rotation of the turning foot. Therefore, it is necessary to turn the swing operation body to open the connecting rod, control the posture of all the rotating legs at once, and place a large number of treads. It improves the ability to traverse muddy or sandy terrain, and also increases the minimum ground clearance by raising the vehicle height to prevent belly rubbing. Further, when the vehicle returns to the sub-device path Ii, the user turns the turning operation body again and turns the rotary foot to make the outline of the entire wheel circular and travels, thereby realizing the advantage of smooth and comfortable movement with little vertical movement.

[Brief explanation of drawings]

Fig. 1 is a front view showing an example of the rotating fast wheel of the present invention. Fig. 2 is a sectional view taken along A-AJJill in Fig. 1, and Fig. 3 is the state of the one shown in Fig. 1' when running on each road S. It is a front view showing
1 is a turning foot, 111 is a tread surface, 2 is a horizontal axis, 21 is a driving body, 3 is a connecting rod, and 4 is a turning operation body.

Claims (1)
