DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, an embodiment of the present invention will be described. In the drawings, reference numeral 1 denotes a roller arranged in a four-wheel shape. It is arranged as a wheel, and as a front steering wheel on the front left and right, so that the board body 2 can run by rolling of these driving and steering rollers 1.

The driving rotation of the driving roller 1 is controlled by the driving device 1.
The drive device 11 includes a small engine 12 as a drive unit and a small engine 1
Transmission mechanism 13 for appropriately converting the driving force of the second to the driving force of rotation
And a power transmission mechanism 14 that transmits the driving force shifted by the transmission mechanism 13 to at least one of the front and rear wheels of the four-wheel roller 1. In the illustrated example, the driving roller 1 is configured as a rear wheel and the steering roller 1 is configured as a front wheel. However, the arrangement before and after these is not particularly limited. May be a driving roller 1.

As the small engine 12, it is planned to use a large one of a normal model engine, for example, an engine having a displacement of about 15 cc.

Further, as shown in FIG. 4, for example, the transmission mechanism 13 receives a driving force from the small engine 12 and applies a one-way clutch 15 for starting the small engine 12.
, And transmitted to the drive input gear 16 via the appropriate number of transmission clutches 18, 22, 26,
The driving roller 1 is configured to be driven to rotate via the power transmission mechanism 14.

That is, the drive input gear 16 is transmitted directly or indirectly to the first gear 17 meshing therewith so as to rotate the input side clutch plate 19 of the first speed change clutch 18 for high-speed drive. It is.

The first gear 17 has the first gear 17.
A second gear 20 having a smaller number of teeth than the second gear 20 is mounted so as to perform the same rotation coaxially, and a third gear 21 having a larger number of teeth than the second gear 20 meshes with the second gear 20. The rotation of the gear 21 causes the input side clutch plate 23 of the second transmission clutch 22 to rotate at a medium speed.

The third gear 21 has the third gear 2
A fourth gear 24 having a smaller number of teeth than one is mounted coaxially and performing the same rotation.
A fifth gear 25 having more teeth than the gear 24 meshes with each other, and the rotation of the fifth gear 21 causes the input side clutch plate 27 of the third transmission clutch 26 to rotate at a low speed.

Then, the driving force input to the first gear 17 causes the input side clutch plates 19, 23, 27 of the respective speed change clutches 18, 22, 26 to rotate simultaneously at high speed, medium speed, and low speed simultaneously. Power can be transmitted quickly when any of them is selected.

Therefore, the transmission clutches 18, 22, 26
When only the first transmission clutch 18 is connected, the output side clutch plate 28 rotates together with the input side clutch plate 19, and a high-speed driving force is transmitted to the power transmission mechanism 14 via the plurality of intermediate gears 29. You.

When only the second speed change clutch 22 is connected, the output side clutch plate 30 rotates together with the input side clutch plate 23, and the medium speed rotation is transmitted to the power transmission mechanism 14 via a plurality of intermediate gears 29. Is transmitted.

When only the third speed change clutch 26 is connected, the output side clutch plate 31 is connected to the input side clutch plate 2.
7, and is directly connected as it is to transmit a low-speed rotation driving force to the power transmission mechanism 14.

At this time, the input shaft 32 of the rotational driving force to the power transmission mechanism 14 is directly connected to, for example, the output side clutch plate 31 of the third speed change clutch 26 and the output side clutch plate of the second speed change clutch 22. 30 is connected to the output side clutch plate 28 of the first transmission clutch 18 via a plurality of intermediate gears 29.

Therefore, the output side clutch plate 28,
If one of the clutches 30 and 31 is connected and rotating, the other output side clutch plates 28, 30 and 31 are also rotating according to the rotation. If the transmission mechanism 13 is formed so as to be controlled so that only one of the transmission mechanisms 26 is always connected, there is no problem, and the transmission mechanism 13 has the simplest structure and can perform a reliable transmission.

As described above, the driving force as the rotational force at each speed is input to the power transmission mechanism 14. The power transmission mechanism 14 is transmitted to a power transmission shaft 34 via a bevel gear 33, and then transmitted from the power transmission shaft 34 to a differential gear mechanism 36 via a bevel gear 35 to drive the driving roller 1. It is formed as follows. As shown in FIG. 6, the power transmission shaft 34 is disposed so as to pass obliquely downward below a starting motor 41, which will be described later, and to be transmitted to a differential gear mechanism 36 via a bevel gear 35. Is formed.

The power transmission shaft 34 of the power transmission mechanism 14 has a universal joint 3 at both ends.
The power transmission shaft 34 is formed of two shafts 38 and 39, one of which is provided with a spline hole and the other shaft is provided with a spline hole. 39 is formed as a spline shaft which is engaged with and inserted into the spline hole so as to be able to expand and contract while transmitting torque as a whole. As a result, shocks, bounces, and the like at the time of traveling caused by irregularities and the like on the traveling surface are absorbed, and the driving device 11
It is possible to improve the damage to itself and the riding comfort for the operator H.

In the structure connected to the driving roller 1 (the rear wheel side in the figure) from the differential gear mechanism 36, the diameter of the driving roller 1 itself may be small. 1 may be larger than the diameter of 1 and may come into contact with the ground or the like.
In order to prevent this, the driving roller 1 is not directly connected to the differential gear mechanism 36, but is formed in two stages using the final transmission gear 53, and the driving roller 1 is arranged one step lower than the differential gear mechanism 36. It has become.

On the other hand, as shown in FIG. 1, the driving device 11 is provided with a control box 4 for remote control.
0 allows the operator H riding on the board body 2 to be operable to appropriately control the on / off and rotation speed thereof. That is, the control box 40
The operation of the transmission mechanism 13 can be performed by selecting each of the transmission clutches 18, 22, and 26, and the start / stop of the small engine 12 can be controlled. Controls are available.

As shown in FIG. 4, the starting of the small engine 12 is performed by a starting motor 41 having a power generation function. The power is transmitted to the one-way clutch 15 via a starting force transmitting device 42 having a built-in clutch that is connected only to start the small engine 12.

Since the starting motor 41 does not need to rotate itself after the small engine 12 is started, the rotation by the power supply is stopped. However, the starting motor 4 is driven by the rotational force of the small engine 12 via a driving roller 43, a belt 44, a driven roller 45, and a one-way clutch 46 provided in the small engine 12 in this order.
1 can be rotated. That is, the torque of the small engine 12 is used to operate the starting motor 41 itself as a generator, and charges the battery 47 which is a power source when the small engine 12 is started.
The generated power is also used as a power source for a spark plug (not shown) of the small engine 12.

Here, the one-way clutch 46 is connected after the start of the small engine 12 in a state in which the starting motor 41 stops rotating by itself, so that the one-way clutch 46 is driven as long as the small engine 12 does not rotate by itself. The rotation motor 43 is formed so that the torque is not transmitted to the starting motor 41 from the route of the roller 43, the belt 44, the driven roller 45, and the one-way clutch 46.

The driving roller 43 and the driven roller 4
5, a tension roller 48 for appropriately adjusting the tension of the belt 44 is provided.
8 is provided with a fan 49 which rotates coaxially and simultaneously to cool the small engine 12.

On the other hand, when the board body 2 travels, steering for changing the traveling direction is performed by a steering rotating plate 50 which is slightly protruded from the front of the board body 2 and is rotatably embedded. It is formed as follows. The turning plate for steering 50 is designed so that the operator H can perform a turning operation with one foot placed thereon. For example, the turning force is transmitted to the steering roller as a front wheel via a lever 51 and a link mechanism 52. 1 is to be converted into a steering force for appropriately changing the angle on the horizontal plane.

Reference numeral 54 in the figure is a control device main body for performing the control by operating the control box 40 for remote control, and reference numeral 55 is a fuel tank of the small engine 12.

As a part of the safety mechanism, a microcomputer is arranged in the control device main body 45 so as to constantly monitor the running state of the roller board itself of the present invention. At the same time, when the operator H is not riding, the traveling is automatically stopped. As a result, even if the operator H performs an erroneous operation, there is no sudden change in speed, and it becomes difficult to fall from the roller board of the present invention, and even if it falls,
It can be stopped automatically on the spot, and runaway accidents and the like can be prevented.

The present invention is not limited to the above-described embodiment, and may be, for example, an electric motor other than the small engine 12, or an apparatus for generating other driving force. Regarding the steering system, there are various types of link mechanisms, and further, there is a type that can be steered without using a link, and thus the present invention is not limited to this type. Further, the present invention is not limited to the arrangement in which the rear wheel-side roller 1 is driven and the front wheel-side roller 1 is driven and steered, and the other structures are not limited to the above-described embodiment. It goes without saying that it is not limited.

Since the angle can be appropriately changed by the steering rotation of the upper operator, the operator H rides on the board body 2 and operates the driving device 11 by remote control to control and rotate the driving roller 1. This makes it possible for the entire vehicle to travel on its own and to easily travel even on a flat place or an uphill.
By steering the operator, the operator H can be moved to any place.

Moreover, the roller board of the present invention, which is unnecessary after the movement, can be carried as it is. For example, the roller board of the present invention can be moved to a passenger car in a distant parking lot by the roller board of the present invention. Since it can be mounted on a passenger car, there is no danger of storage and loss, and there is no need for a special storage place.

At this time, the drive unit 11 is connected to the engine 12 via an appropriate number of transmission clutches 18, 22, 26.
The transmission clutches 18, 22, 26 are formed to transmit the driving force from the driving device to the driving roller 1.
By selecting and connecting as appropriate, for example, when a strong rotation torque such as uphill is required, the gear ratio is set to the low gear ratio, and when high speed rotation such as increasing the speed is required, the gear ratio is set to the high gear ratio. , Or in the case of normal operation, the medium-speed gear ratio can be appropriately selected.
Even so, it is possible to make it possible to travel in any place.

Further, the driving device 11 is formed so that the engine 12 as a power source can be started by a starting motor 41, and the starting motor 41
, The power storage device (battery 47), which is the power source of the engine drive auxiliary motor and the starter motor 41, can be charged, so that the engine 12 can be started with one touch, and the start of the engine 12 can be started. The replenishment of the power to be performed can be automatically performed at the time of traveling, which also contributes to simplification of the mechanism of the electric system, and can reduce the weight and size of the whole.

Then, the steering by the operator H is converted into a steering force for appropriately changing the angle of the steering roller 1 in the horizontal plane by the steering rotating plate 50 provided on the board body 2 and capable of one-handed operation. Since it is formed, the steering operation is performed with one foot without the need for the operation of the operator H by hand, and the operation of the hand is only performed by remote control driving to ensure the drive control.
