2. Description of the Related Art Conventionally, a pinion gear of another drive system having a driving torque (torque) necessary for climbing a slope is provided on the locomotive side so that a locomotive running on a track can climb a steep slope. On the other hand, on the side of the traveling equipment, a rack rail is laid between ordinary rails, and the pinion gear on the locomotive side meshes with the rack rail, so that the locomotive climbs uphill, the so-called Abt method. Has been adopted. In this apt system, a drive system for a pinion gear for traveling uphill provided in a locomotive is provided separately from a drive system for wheels traveling on a flat track, that is, traveling on a normal track. That is, the abto type locomotive is provided with a plurality of drive systems (for pinion gear drive and wheel drive) having a motor and a speed reducer having substantially the same functions.

[0003]

However, in the above-mentioned conventional ABT system, since a drive system for uphill traveling and a drive system for flat traveling are separate, a plurality of expensive driving devices must be provided. However, there was a problem that the cost of the locomotive was very large. Also, a separate drive system,
There is a problem that the size of the locomotive cannot be reduced because the locomotive must be provided in the locomotive. Especially,
Since a battery locomotive used in tunnel excavation work needs to travel in a narrow tunnel, it has been difficult in some cases to use a conventional apt method.

An object of the present invention is to reduce the cost and
It is an object of the present invention to provide a locomotive for steep hill-climbing capable of climbing a steep hill without increasing the size of the locomotive, and its traveling equipment.

[0005]

And a steep slope auxiliary wheel 30 rotatably attached to the trolley 28. When the battery locomotive 10 travels on a flat road, the outer ring 32 of the wheel 16 comes into contact with the head of the rail 150 as a tread and travels on the rail 150.

The structure of the battery locomotive 10 will be described in more detail. FIG. 2 is a partially omitted cross-sectional view of the battery locomotive 10 according to this embodiment.
2, the brake mechanism provided on the shaft of the wheel 16 and a brake control device for controlling the brake mechanism are omitted. As shown in FIG. 2, each of the wheels 16 is
It is attached to 0. The wheel has a steel outer ring 32 for traveling on an H-shaped rail, and a pinion gear 44 attached to a tip of an extension 42 of a shaft 40 further protruding from the outer ring.

In order to drive the pair of wheels 16, 16, a motor 46 connected to the battery 14 and a gear box 48 for adjusting the rotation of the motor 46 and transmitting the rotation to the shaft 40. And a shaft 40 to which the pair of wheels 16, 16 is attached passes through a gear box 48. In the gear box 48,
A gear (not shown) fixed to the shaft 40 meshes with a predetermined gear (not shown) in the gear box 48 selected by operating the operation switch 20, and rotation of the motor 46 is transmitted to the wheels 16. It is supposed to be. As can be understood from FIG. 2, in this embodiment, a pair of wheels 1
For each 6, 16 two substantially identical motors 46 and gearboxes 48 are provided.

Referring to FIG. 2 and FIG. 3, which is an enlarged view of the wheels, the wheels 16 of the battery locomotive 10 will be described in more detail. As shown in FIGS. 2 and 3,
The outer ring 32 of the wheel 16 and the pinion gear 44 are
And the rotation of the shaft 40 causes the outer ring 32
And the pinion gear 44 rotate in the same manner. In this embodiment, the pinion gear 44
One gear is formed, and meshes with a rack rail described later. Further, as described above, the pinion gear 44 protrudes from the outer ring 32 to the outside of the locomotive 10. In this embodiment, the outer diameter of the outer ring is about 400 mm, and the outer diameter of the pinion gear is about 150 mm.
It is.

Next, the auxiliary wheel carts 24 and 28 and the auxiliary wheels 26 and 30 according to the present embodiment will be described. As shown in FIG. 1 and FIG.
Numerals 28 are provided at the forefront and rearmost portions of the locomotive, respectively. The auxiliary wheels 26 and 30 are made of steel or have a structure in which urethane rubber or the like is formed around a steel inner ring. Also, from the rail 150 to the auxiliary wheels 26,
The distance to the lower end of the pinion 30 is equal to the distance from the rail 150 to the lower end of the pinion gear 44 (see the dotted line A in FIG. 1). That is, as described later, when the rack rail and the pinion gear 44 mesh with each other, the auxiliary wheels 26, 3
0 is in contact with the rack rail and the battery locomotive 10
Has come to support.

The battery locomotive 1 constructed as described above
An explanation will be added for the case where 0 runs. On a flat road, a pair of rails 150 are laid on the track. Therefore, in the battery locomotive 10, the wheels 16
The outer ring 32 is in contact with the head of the rail 150 using the outer ring 32 as a tread surface. Therefore, the rotation of the motor 46 is
The battery locomotive 10 travels on the rail 150 by being transmitted to the outer wheel 32 of the wheel 16 via the. At this time, the rotation of the shaft 40 also causes the pinion gear 44 to rotate, but this is merely idle. As can be understood from the above, on a flat road, the traveling equipment is a pair of rails 1 on which the outer ring 32 can travel.
50.

On the other hand, on an uphill road, a pair of rack rails 160 are laid so that the pinion gears 44 can mesh with each other (see FIG. 2). This rack rail 160
Is mounted on the rail support member 162 as shown in FIG. As described above, since the distance from the rail 150 to the lower ends of the auxiliary wheels 26 and 30 is equal to the distance from the rail 150 to the lower end of the pinion gear 44, when the rack rail 160 is laid, the pinion gear The 44 engages with the rack rail 160, and the auxiliary wheels 26 and 30 come into contact with the rack rail 160.

Further, as described above, the rack rail 160 has such a height that the outer ring 32 of the wheel 16 is separated from the rail 150 when the pinion gear 44 meshes with the rack rail 160, that is, the auxiliary wheels 26, Only at 30 or the like, the battery locomotive 10 is positioned at such a height as to be supported. Therefore, as shown in FIG. 4, on the uphill road, the battery locomotive 10 is supported by the auxiliary wheels 26 and 30, and the rotation of the motor 46 is
By being transmitted to the pinion gear 44 of No. 6, the vehicle can travel on the rack rail 160. At this time, the rotation of the shaft 40 also rotates the outer ring 32, but the outer ring 32 floats and therefore idles.

Accordingly, on an uphill road, the traveling equipment is constituted by a pair of rack rails 160 on which the auxiliary wheels 26 and 30 are mounted and on which the pinion gears mesh. The rack rails are composed of the auxiliary wheels 26 and 30. Thereby, the battery locomotive 10 is supported, that is, arranged at a position where the outer ring 32 floats.

As described above, the outer diameter of the pinion gear 44 is set smaller than that of the outer ring 32 of the wheel 16.
As a result, the rotational force (torque) transmitted to the pinion gear 44 can be increased, and the vehicle can travel on a steep uphill road. On the other hand, on a flat road, it is possible to use a wheel 16 having a large outer diameter to travel at a higher speed.

According to the present embodiment, the outer ring for traveling on a flat road and the pinion gear for traveling on an uphill road are rotated by a common driving system, so that many driving systems are not provided.
It becomes possible to realize a battery locomotive that can travel on steep slopes.

Further, since the outer diameter of the pinion gear is set smaller than the outer diameter of the outer race for traveling on a flat road, the difference in the outer diameter allows the vehicle to travel at a higher speed on a flat road and to climb up a hill. In road running, it becomes possible to realize a battery locomotive that can run with a large rotational force.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the invention described in the appended claims, which are also included in the scope of the present invention. Needless to say, this is done.

For example, in the above-described embodiment, if the pinion gear 44 is configured to be detachable from the shaft 40, the pinion gear 44 can be removed to be used as a normal battery locomotive.

Further, in the above embodiment, as shown in FIG.
0 is placed and supported, but the present invention is not limited to this.
The rack 60 may be placed on the rack rail 160 and dug down.

Further, in the above-described embodiment, the rail 150 for flat traveling is laid on the traveling equipment on which the rack rail 160 is laid, but this is not necessary and may be omitted. It is clear.

Further, in the above embodiment, auxiliary wheels are provided at the forefront and rearmost portions of the main body of the battery locomotive 10, but the number and position of the auxiliary wheels are not limited to this. Instead, more auxiliary wheels may be provided according to the size and weight of the battery locomotive, or auxiliary wheels may be mounted at other positions.

Further, in this specification, the function of one member may be realized by two or more physical members, or the function of two or more members may be realized by one member. .
