Abstract

PURPOSE:To move a vehicle to run in a desired direction without converting the direction of the vehicle, by making the wheels other than the driving wheels into caster wheels, giving a rotation drive to the driving wheels while fixing the driving wheels in a desired direction, and making the caster wheels follow the direction of the driving wheels consequently. CONSTITUTION:By operating a primover 3 and laying down the right and the left handle levers 6 and 6 to the front side, the vehicle runs forward, and by laying down them to the rear side, the vehicle runs backward. When the vehicle is necessary to run sideways (in the upper direction in the figure) while the car bodies 1 and 12 are positioned as they are, a lever 10 is handled to release the lock of a driving vehicle 2 and the driving body 1 while caster wheels 13 are locked to stop the rotation. Then the handle levers 6 and 6 are laid down to place the right side driving wheel 7 at the frontward running position and the left side driving wheel 7 at the backward running position, and the driving vehicle 2 is rotated counterclockwise within a circular opening 1a. When the driving vehicle 2 is rotated about 90 deg., the handle levers are returned to the neutral position to stop the rotation, and to lock the driving vehicle 2 to the driving side body at the same time. After that, the handle levers are laid down frontward and the driving wheels are operated.

Conventionally, this type of omnidirectional vehicle has a four-wheel steering system in which all the wheels that support the vehicle can be steered, or a vehicle with a 45° angle on the circumference of the wheel. Some vehicles were equipped with a plurality of 7-Lee rollers tilted at an angle, and by appropriately combining the rotational directions of each wheel, it was possible to travel forward and backward, horizontally, horizontally, diagonally, and spin turns.

However, the conventional all-wheel rudder type mentioned above has problems such as a complicated structure, easy failure, and high manufacturing cost. In addition to the above-mentioned problems, there are other problems such as the fact that it is difficult and unsuitable to operate on uneven road surfaces, and omnidirectional driving vehicles are not generally popular at present.

The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to provide an omnidirectional vehicle that has a simple structure, is easy to operate, and can be widely used at a low price. be.

One aspect of the omnidirectional traveling vehicle of the present invention is that one of the three or more wheels that support the vehicle body is a driving wheel, and the wheels other than the driving wheel are caster wheels, and the vehicle body is When moving the vehicle in a desired direction, the direction of the vehicle body is adjusted by fixing the direction of the drive wheels in the desired direction and applying rotational driving force, thereby causing the caster wheels to follow the direction of the drive wheels. It is characterized by being able to run and move in any direction without changing its orientation, and also by changing the supination of the drive wheel in any direction at its mounting position, or by changing its supination from its mounting position. The vehicle is characterized by being able to change its direction by turning around a deviated position, and furthermore, a driver's seat is provided on the vehicle body, and the direction is changed in a direction that matches the direction of the driving wheels. It is characterized by the following.

Furthermore, the present invention is characterized in that the vehicle is divided into parts and drive wheels are arranged on one side and caster wheels are arranged on the other side so that they can mutually roll. The feature is that the caster wheels are locked when the machine is being changed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a drive-side vehicle body, and a circular opening 1a is provided in the center thereof.

Inside the circular opening 1a is a drive wheel 2 having a disc-shaped body.
is rotatably inserted.

3 is a prime mover, and its rotational driving force is transmitted to the input sides of left and right transmissions 5, 5 through a transmission mechanism 4 as appropriate. The transmission 5 is composed of, for example, a small hydraulic pump, a hydraulic motor, and a control mechanism that controls the rotation direction and rotation speed of the hydraulic motor. The rotational direction and rotational speed of the left and right drive wheels 7, 7 are controlled to allow the vehicle to travel in a desired direction and speed.

As is clear from FIG. 3, the outer periphery of the drive 112 is vertically sandwiched and regulated by the drive side vehicle body 1, and when driving on an extremely uneven road surface, the drive $ Even if 2 swings up and down, it will not come off from the drive side vehicle body 1.

Further, a friction plate 8 is provided at an appropriate position on the outer circumference of the drive wheel q12, preferably at a position facing each other across the diameter, and this can be moved in and out of the outer circumferential surface of the drive wheel 2 by a lever 10 provided near the driver's seat 9. The driving wheel 2 and the driving vehicle body 1 can be integrally and reliably locked by frictionally engaging the inner wall surface of the circular opening 1a of the driving vehicle body 1 during driving.

A cargo platform side vehicle body 12 is connected to the rear of the driving side vehicle body 1 via a hinge 11, and is adapted to roll with respect to the vehicle body so as to follow an uneven traveling road surface.

Caster wheels 13 are attached to the cargo platform side vehicle body 12, and can be locked as necessary by appropriate operation from the driver's seat 9. In this case, it is preferable to configure it so that it is interlocked with the lever 9 described above.

Since the vehicle of this embodiment is configured as described above, in the state shown in FIG.
, 6 to move forward, and vice versa to move backward to move backward.

If you want the vehicle bodies 1, 12 to travel (traverse) in the lateral direction (upward in FIG. It is moved back from the inner wall surface of the opening 1a to release the frictional engagement and lock the caster wheels 13 from rotating.

Next, when the right operating lever 6 is pushed forward and the left operating lever 6 is pushed backward at the same time, the right drive wheel 7 rotates forward.
Since the left drive wheel 7 rotates backward, the drive wheel 2 rotates counterclockwise within the circular opening 1a.

When the drive wheel 2 rotates approximately 90 degrees and faces the state shown in Fig. 4,
The operating levers 6, 6 are returned to the neutral position to stop their rotation, and the lever 9 is operated again to lock the drive II2 to the drive side vehicle body 1. At this time, the caster wheels 13 are unlocked.

In the state shown in Figure 4, when the operating rods 6, 6 are tilted forward, the drive wheel 7
, 7 move forward, and the entire vehicle body consisting of the drive side vehicle body 1 and the cargo platform side vehicle body 12 moves in the direction of the arrow. At this time, the caster wheels 13 also change direction in the running direction as shown in the figure.

In the above embodiment, the vehicle bodies are the driving side vehicle body 1 and the loading platform side vehicle body 12.
Although the vehicle body 1 is divided into two parts, they may be constructed integrally, or the vehicle body 12 on the platform side may be arranged on both sides with the vehicle body 1 on the drive side sandwiched in the center.

Further, the number of wheels including the drive wheels and caster wheels may be any number greater than or equal to 3 as long as the arrangement is such that the vehicle body can be supported while traveling, and at least one of these wheels should be the drive wheel. The drive wheel is structured to be able to change its direction in any direction, and the other caster wheels are configured to follow this direction.

Further, in the embodiment described above, the drive wheel 2 is provided in the vehicle body 1 so as to be freely rotatable, and by rotating the drive wheel 2, the drive wheel 7 is rotated.
Although the hM is constructed so that the direction of the wheel can be changed and the direction is fixed by the friction plate 8, the present invention is not limited to this, and the drive wheel can be changed in any direction relative to the vehicle body, and the direction Any structure may be used as long as it can be fixed to. The direction of the drive wheel can be changed by rotating the drive wheel at its mounting position, or by turning the drive wheel around a position offset from its mounting position. Any method that allows the change to occur may be used.

1 mile class'' Wheels other than the drive wheels are caster wheels, and when changing the direction of the drive wheels to move the vehicle in that direction, the rotational driving force is applied while the drive wheels are turned to the desired direction and fixed in that direction. As a result, the direction of the caster wheels follows the direction of the drive wheels, making it extremely easy to drive forwards and backwards, horizontally, diagonally, or spin turns without changing the direction of the vehicle body. It can be easily implemented due to its simple structure and operation, and can be widely used at low cost.
