Abstract

PURPOSE:To easily change the direction of a car on a running road of a narrow width, by mounting a car body lifting jack mechanism to the bottom central part of a car body and rotating said jack mechanism with the car body in the horizontal direction. CONSTITUTION:A direction changing device 8 is mounted to the bottom central part of a car body 2 of a crawler typed travelling car 1. This device 8 is constituted by a jack mechanism 6 and rotary mechanism 7. Change of direction of the car 1 is operated in such a manner that the mechanism 6 is operated to extend a jack shaft 9 and cause a condition of crawlers 4, 4' lifted from the running road surface and then the mechanism 7 is operated to rotate the car 1 and the mechanism 6 about a rotary shaft 10.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a direction changing device for a vehicle that freely travels on a floor surface.

[Technical background of the invention and its problems] Conventionally, R a
In the case of a car that runs using -y, the relative speed of the left and right cloaks is adjusted depending on the Al11 curve of the road to steer or change direction. In other words, if the curve of the running road is small, the left and right crawlers are controlled by speed control, and as the shoulder angle becomes larger, one crawler is stopped to perform steering. , if a certain VH performs a complete direction change, the left and right claws 2
The direction of rotation may be reversed. However, since the running surface or the two claw surfaces are not necessarily in an ideal state for changing direction at a sharp angle, it is not always possible to steer the vehicle as intended by the operator. In other words, there is a gap between the crawlers and the running surface, and it is necessary to constantly repeat corrective operations for the target turning direction.

For this reason, the cloakroom vehicle must be allowed sufficient space on the travel path, and conversely, if the road cannot be sufficiently wide, the vehicle may have to give up on proceeding. Moreover, if the driver does not get into the car and remotely controls the car, direction corrections cannot be made in a timely manner, so this drawback is further amplified and the route through which the car can be driven becomes even more limited.

Cars that run using wheel tubes are generally steered by changing the direction of the front wheels (using all mechanisms). In this case, if the rotating diameter is large and the passage width is not sufficient, it will not be possible to turn at a right angle at t/1. In order to eliminate this drawback, the vehicle has a structure that allows all vehicles to be steered.

However, in this case, a plurality of wheel steering motors are required to change the direction, and there are problems such as the need for complex control in order to proceed in a predetermined direction.

On the other hand, a method of installing turn tapes and ilts on the running path itself can be considered, but this method requires a large number of tarps/tables, so installation is limited from an economical point of view.

[Purpose of the invention]

The present invention seeks to eliminate the above-mentioned drawbacks and consists in providing a device which allows a vehicle to easily turn around on a smooth road.

[Summary of the invention]

That is, the present invention is directed to a table comprising a jack mechanism for a car body lift mounted at the center of the lower part of a car body, and a rotating mechanism capable of simultaneously rotating the car body and the jack mechanism for a single lift 10 times in the horizontal direction. It is a conversion device.

[Embodiments of the invention]

Hereinafter, an embodiment of the present invention will be described in which a vehicle direction changing device according to the present invention is installed in a two-wheeled vehicle as shown in FIG. 1, FIG. 2, and FIG. 3.

A direction changing device [8] consisting of a jacking mechanism 6 and a rotating mechanism 7 is attached to the lower center 11 of the vehicle body 2 via a jacking shaft 9 and a rotating shaft 1Ot.

Next, the operation of the present invention constructed as described above will be explained.

By increasing the difference in rotational speed, the steering performance increases. However, if the driving road is narrow and the vehicle becomes steep beyond where the vehicle is traveling, the above method will not be able to steer the vehicle.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to easily and accurately change the direction of a crawler-type traveling vehicle 1, regardless of the condition of the road surface, etc., for example, when the width of the traveling vehicle path is narrow. It also makes it easier to change direction by remote control.
