Abstract

PURPOSE:To enable execution of smooth, quiet, and stable running and to enable the increase of the durable force of each part by a method wherein rotation of an inner wheel is transmitted to an outer wheel through a buffering body between two engaging parts peripherally formed to the sides, positioned facing each other, of the outer and inner wheels of a power vehicle drive wheel. CONSTITUTION:When, with an engine 3 driven, a rotary shaft 10 is rotated, an inner wheel 12 engaged therewith is rotated. Since a buffering body 19 is located throughout an area ranging between a recessed engaging part 16 formed in the inner wheel and a window-holeform engaging part 18 formed facing the engaging part 16 and in an outer wheel 14 concentrically and loosely rotatably engaged with a shaft cylinder part 11 of the inner wheel, rotation of the inner wheel is transmitted to an outer wheel 14 through a buffering body in a compressed state. Thereby, by means of an engaging body 17 of the outer wheel 14 engaged with the engaging part of a monorail 5, a power vehicle 1 is moved forward and backward over the monorail. When a gap is produced between the engaging body 17 and an engaging part 7, the speed of rotation in the direction of forced forward movement of the outer wheel 14 is increased to a value higher than that of the inner wheel 12 through the restoration force of the buffering body 19, the gap therebetween is reduced to zero before generation, and a trouble, e.g. jolting, can be prevented from occurring.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a drive in a power vehicle that runs on a single track built on a steep slope in a mountainous area [Prior Art] Generally, it is used in a mountainous area with poor footing. Single-rail motor vehicles are used as equipment for transporting agricultural products such as fruits and cargo such as wood.

As shown in Figure 1, the above-mentioned power vehicle is usually a
A loading or passenger trolley 2 is connected to the front or rear of the powered vehicle 1, and by driving the engine 3 of the powered vehicle, it moves forward or backward on a single rail 5 that is constructed at an appropriate height above the ground using a support 4. However, when the vehicle reaches the loading/unloading point, the brakes of the motor vehicle are applied and the vehicle automatically stops.

The running of the motor vehicle is achieved by meshing the drive wheels 6 provided on the motor vehicle 1 with ranks (or pin holes) 7 provided along the single rail 5. In addition to the single wheel, the drive wheel mentioned above is a special public model No. 58-23267, No. 4738.
There are also two-wheeled models like No. 5.

[Problem that the invention seeks to solve]

By the way, the above-mentioned single-rail rack is generally formed by bending a band with a predetermined pinch, and the single-rail rack is added in the longitudinal direction to form the required length. Therefore, the pitch interval of the racks mentioned above is not accurate due to dimensional errors. Furthermore, since the single rail is curved left and right or vertically at various places, errors occur in the pitch intervals of the rack as well, and this also applies to single rails with pin holes.

Therefore, while a power vehicle is running, discontinuous play occurs continuously between the meshing portions of the drive wheels and the single rail, causing chatter and impact noise.

This problem occurs not only when the drive wheel is one wheel, but also particularly when the drive wheel is of the two-wheel type.

The object of the present invention is to eliminate the above-mentioned disadvantages, thereby ensuring smooth, quiet and stable running, and increasing the durability of each part.

[Means for solving problems]

In the drive device for a single-rail power vehicle according to the present invention, the drive wheels of a power vehicle running on a single-rail are constituted by an outer ring and an inner ring that are connected to each other around the same axis so as to be freely rotatable in forward and reverse directions. is provided with meshing bodies that can mesh with the meshing parts of the single rail at equal intervals on the circumference, and a shaft cylinder part that can be connected to the rotating shaft of the power vehicle is provided on the inner ring, and the outer ring and inner ring are connected to each other. The rotation of the inner ring is transmitted to the outer ring via the spars by interposing a buffer between both engaging parts formed in the same number of engagement parts in the circumferential direction on the corresponding side surfaces. It is.

[For production]

According to the present invention, when the rotary shaft is driven by the engine of a power vehicle, the inner ring is rotated by the shaft cylinder connected to the shaft, and this inner ring is connected to the outer ring rotatably connected to the inner ring. On the other hand, since a buffer body is interposed between the respective engaging parts, the rotation of the inner ring is transmitted to the outer ring via the buffer body, and furthermore, the meshing body of the outer ring is in a meshing relationship with the single rail. Therefore, the entire drive wheel made up of the inner and outer wheels rotates, and the motor vehicle runs on a single rail.

Furthermore, if a gap occurs due to instantaneous play between the meshing body of the single rail and the outer ring, the outer ring will rotate in the rotating direction due to the buffer, and the drive wheel will continue to drive properly. be.

〔Example〕

Hereinafter, the present invention will be explained with reference to the embodiments shown in the figures.
As explained above in FIG. 7 is a meshing part consisting of a rank or pin hole, etc. that meshes with the drive wheel 6, and 8 and 9 are upper rollers that sandwich the single rail 5 from above and below. They are a wheel and a lower roller.

As shown in Fig. 2.3.4, the drive wheel 7 includes an inner ring 12 having a cylindrical portion 11 formed in the center, and an axially extending portion on the outer periphery of the cylindrical portion 11 of the inner ring so as to sandwich this inner ring in the middle. It is rotatable from both sides and fitted loosely, and the middle part is connected to the inner ring 12.
It is composed of an outer ring 14 that circumscribes a single rail 5 which is integrated on the left and right sides by a caulking pin 13 inserted through a large diameter hole 12' of
A spline 15 is carved to mesh with the rotating shaft 10 supported by the power vehicle 1, and a thick wall 1 near the outer periphery of the inner ring is formed.
2', several recessed engaging portions 16 are arranged radially at equal intervals in the circumferential direction (in the example shown, there are 6 recessed engaging portions 16 on one side).
i) It is formed. The outer ring 14 also has a meshing body (a pinion is shown in the figure) 1 that meshes with the meshing portion 7 of the single rail 5.
7, and the same number of window-like engaging portions 18 as the engaging portions 16 of the inner ring 12 (in the illustrated example, 12 on the left and right in total) are formed at equal intervals in the circumferential direction on the side surface. ing. Reference numeral 19 denotes a buffer body made of a spring, rubber, etc., which is interposed between the re-inspection parts 16 and 18 formed on both surfaces of the inner ring 12 and the corresponding surface of the outer ring 14, and the buffer body is made of spring, rubber, etc. By being compressed, the rotation of the inner ring is transmitted to the outer ring.

Reference numeral 20 denotes a side plate that is brought into contact with the outer surface of the outer ring 14 to prevent the buffer member 19 from being removed. The left and right sides are connected so that they can rotate together with 12. 23
is a ring-shaped holding plate which is slidably contacted with the outer periphery of each of the left and right side plates 20, and is fixed to the outer ring 14 with bolts 24.

The drive device configured as described above drives the engine 3 and rotates the rotating shaft 1.
When the inner ring 0 is rotated, the inner ring 12 meshed with the inner ring 12 rotates, and the inner ring 12 is fitted concentrically to the shaft cylindrical part 11 of the inner ring so as to be freely rotatable. Since a buffer body 19 is interposed between the mated outer ring 14 and a window-shaped engaging portion 18 formed corresponding to the retaining portion 16, the rotation of the inner ring is in a compressed state. The power is transmitted to the outer ring 14 via the buffer, and therefore the power vehicle l travels forward (reverse) on the single rail by the meshing body 17 of the outer ring 14 that engages with the meshing part of the single rail 5. It is.

However, if a pitch error occurs in the meshing portions such as the meshing portion, for example, if the pinch interval at a specific location is wide, a gap will momentarily appear between the meshing body 17 of the outer ring and the meshing portion 7 that should be meshed. When a gap is formed between the engaging body 17 and the engaging portion 7, the rotation of the outer ring 14 in the pushing direction with respect to the inner ring 12 is accelerated by the restoring force of the buffer body 19, thereby closing the gap. As a result, the drive wheel 6 itself is constantly maintained in a state of engagement with the meshing portion, and the above-mentioned problems such as rattling can be eliminated.

〔Effect of the invention〕

According to the present invention, for a power vehicle that runs on a single rail due to the rotation of the driving wheel, even if the meshing portion of the single rail that meshes with the driving wheel has a pitch error or a large or small variation in pitch interval, Since the drive wheels are constantly rotated in close contact with the meshing portions of the single rail, stable running is possible and adverse effects on various parts can be eliminated.
