Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road surface and track running type multi-way car, and more particularly to a road surface and track running using pneumatic tire type wheels. The present invention relates to a multi-way car which is provided with a guide roller for lowering the guide roller from a retracted position to an operating position where it engages with a rail.

[0002]

In order to be able to run on rails with a small bend radius, the bogie is provided with guide rollers with wheel flanges that guide the pneumatic tired wheels of the road car while running on the rails. This is known, as can be seen by referring to German Patent 4,316,631. In this case, the guide roller is rotatably attached to a rotating arm operated by a hydraulic device, and can be lowered so as to mesh with the rail for traveling on the rail. The angle of descent of the rotating arm is constant, and the bogie is free to turn around an axis perpendicular to the axle of the wheels traveling on the road surface.

However, it has been found that such structures are not always available. This is because, in a special zone such as a marshalling yard where two-way cars enter, pneumatic tire wheels on the rails may damage various devices mounted on the rails, such as induction magnets and shaft counters.

Even worse, the bogie can, in principle, be adapted to different track widths by replacing the guide rollers, but up to the lateral distance of the pneumatic tire wheels of such a multi-way car. Cannot be changed. The pneumatic tired wheels of a multi-way car must not only transfer the weight of the vehicle body to the rails, but must also function to keep the pneumatic tired wheels and the rails in constant contact and to drive and brake with frictional forces. Since the axial distance of pneumatic tire wheels is constant, the distance will be determined to fit the narrower track of the various tracks. Otherwise, the contact between the pneumatic tire wheels and the rail is lost and the driving function of the road car can no longer be guaranteed.

Since the guide device configured as a bogie allows the road car to travel on the rail exclusively when in the operating position, it is difficult to change the pressing pressure between the pneumatic tire type wheel and the rail. There is.

[0006]

[Problems to be Solved by the Invention] In order to further expand the application range of a multi-way car capable of traveling on such a road surface and a track and to meet the increasing demand, an object of the present invention is to travel on a rail. It is a road car that can travel on roads and tracks without losing the guiding, driving, and braking functions required when doing, and can be introduced into any running zone or track with any existing track width. It is an object of the present invention to provide a guide device as described above, and thereby to meet the above-mentioned demand for the multi-way car.

[0018]

According to the inventions of claims 1 to 3, firstly, it is possible to realize a guide device for causing a road car to travel on a rail. This guide device can function both as a guide device and as the sole drive device.

In particular, it is possible to make an intermediate adjustment in which the pneumatic tire type wheels of the road car and the guide rollers exert a driving force or a braking force.

Furthermore, the structure can easily be adapted to different track widths of the traveling track without the provision of a specific lower limit. This is because the guide device can have a driving function or a braking function when the axial distance between the tires is too large.

The advantages of claims 4 and 5 are:
The drive engine of the road car can be mechanically connected to the guide rollers via a mechanical or hydraulic transmission. In particular, this power transmission can be connected and disconnected via suitable connecting means.

Another advantage of the inventions of claims 1 to 5 is that the pneumatic tire wheels of a multi-way car can be changed to any height on the rail. Therefore, it becomes possible to adapt the multi-way car to any orbit actually used. When the pneumatic tire type wheel is removed from the drive, the drive is performed only through the guide roller. In this running condition, the measuring device arranged directly adjacent to the rail surface is not damaged by the pneumatic tire wheels.

Particularly, since the rotary arm is rotatably mounted on the drive shaft, the rotary arm forms one vibration system together with the pneumatic tire type wheel. Vibration due to unevenness of the ground or traveling and braking action is reduced by the shock absorber provided on the drive shaft.

The guide device according to the sixth to eleventh aspects of the present invention enables the multi-way car to be quickly and sufficiently adapted in any operation without any problem.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, four embodiments schematically showing the present invention will be described. It is possible to drive a road surface and a track using pneumatic tire type wheels, and the pneumatic tire type wheels are provided with a pair of guide rollers each having a guide wheel flange for track running. By lowering from the retracted position to the operating position where it meshes with the rail of the track through the adjusting means for operating the rotary arm, it is possible to run on rails with a small bending radius or with pneumatic tire type wheels.

FIG. 1 schematically shows a multi-way car MF, in which a chassis 10 below a driver's cab 11 has a drive engine AM, two axles 22 supporting pneumatic tire type wheels R, and a power drive. Two pairs of guide rollers 12 and 14 driven by the transmission VG are mounted.

The transmission means of the axle 22 for driving the pneumatic tire wheel R are not shown in FIG. 1 in order to simplify the drawing. Each pair of guide rollers 12 and 14 constitutes a part of a guide device FE that functions to guide the multi-way car MF on the track SW. Guide roller pair 1
2, 14 are attached so as to be able to rotate each time via a rotary arm 16 connected to a support pin 15 fixed to the chassis 10, and are adjusted from the retracted position shown by the chain double-dashed line by adjusting means which is a hydraulic cylinder 17. It is moved to the actual operating position and is engaged with the rail of the track SW.

That is, the guide rollers 12, 14 constitute a self-propelled track traveling mechanism, and the rotary arm 16 of the track traveling mechanism extends from the retracted position to the operating position behind the axle 22 of the pneumatic tire type wheel R. The reverse is also possible.

The operating position in each case is fixed by a shut-off means or a fixing means, which has a shut-off valve provided in a hydraulic circuit (not shown) which operates hydraulically, electromagnetically or mechanically.

FIG. 3 shows a second embodiment of the guide device FE. Here, in order to simplify the drawing, only the chassis 10 is shown as the multi-way car MF.

The pneumatic tire type wheel R mounted on the axle 22 of the multi-way car MF is mounted on the rail 23 of the track SW. Each axle 22 is attached to chassis 10 in a conventional manner using springs 24 and dampers 25. The center of the axle 22 is provided substantially parallel to the installation surface of the track SW and is attached to each one bracket 26 having a slope like a roof, and this bracket is attached to the axle 22.
It is integrated with. The rotary arm support 30 is pivotally mounted relative to the bracket 26 about a journal 27 extending along the axis Z. Rotating arms 33, 3
4 is connected to a rotary arm supporter via rotary arm shafts 31 and 32, and these rotary arms 33 and 34 are connected to the guide roller shaft 3 at the end opposite to the rotary arm support 30.
A pair of guide rollers 42 and 43, which support 5 and 36 and have wheel flanges on their guide roller shafts, are rotatably attached. The rotating arms 33 and 34 are adapted to be moved from the retracted position to the operating position or vice versa via the hydraulic adjusting means 37 and 38.

The guide device FE consisting of the rotary arm support 30, the rotary arms 33, 34 and the guide rollers 42, 43 arranged in pairs as described above is swivelable about the central axis Z each time. Forming a bogey.

That is, the guide rollers 42 and 43 form a part of the bogie, and the swivel axis 27 of the bogie is the track SW.
The axle 22 of the pneumatic tire wheel R which is perpendicular to the
It can be seen that they are arranged in a position where they overlap with each other.

Also in the example of FIG. 3, the multi-way car MF is provided with two guide devices FE. An engine (not shown) drives one or both axles 22 by a well-known method via a transmission gear 51 and drive shafts 52 provided on one or both axles 22.

The shifting gear 53 is motively coupled to the transmission gear 51 via a coupling member (not shown), and a universal joint shaft 54 is attached. The universal joint shaft 54 transmits the torque transmitted from the speed change gear 51 to the shifting gear 53 to the intermediate gear 56 provided in the guide device FE. The intermediate gear transmits the transmission torque to the guide roller shafts 35, 3
6 to the guide roller pair 42, 43
Drives the multi-way car MF in the operating position, or exerts a braking action depending on the operating state of the car engine. In addition, the second guide device F is attached to the intermediate gear 56.
Another universal joint shaft 55 that can drive and brake the E guide roller shafts 35 and 36 may be provided.

That is, at least the pair of guide rollers 42, 43 is constructed as a self-propelled orbital traveling mechanism, and is dynamically connected to the driving engine AM (see FIG. 1) of the multi-way car MF. To be understood. With such a configuration, the multi-way car is provided with a guide device for traveling on the rail, and the guide device is shown in FIG.
As a guide device as shown in FIG.
Will also function as the only drive.

Referring to FIG. 3, a pair of guide rollers 42, 4
3 is provided with braking devices 64, 65 known per se.

The operation procedure of the above guide device FE is as follows.

When traveling on the road, the multi-way car M
The guide device FE of F is fixed to the retracted position via a blocking means (not shown) that acts on the adjusting means as is well known. When the multi-way car MF is arranged on the rail 23 for towing or propulsing one or a plurality of vehicles, the multi-way car MF is operated on the rail 2 of the track SW.
3 travels, and after releasing the shut-off valve as the shut-off means, each pair of guide rollers 42, 43 provided with the wheel flanges 40, 41 of the two guide devices FE is adjusted by the adjusting means 17 or 37, respectively. , 38 and the rotary arms 16 or 33, 34 to move from the retracted position to the operating position as shown in FIG. 1, for example. The operating position is the wheel flange 40 of the guide roller pair 42, 43.
This is achieved when 41 engages with rail 23 (Fig. 2
And FIG. 3).

As a result, in the operating state of the guide device FE, the multi-way car MF guides the axle 22 along the rail 23 of the track SW.

The drive in this operating state is carried out exclusively via the pneumatic tire wheels R. In this operating state,
The weight of the multi-way car MF is exclusively for pneumatic tire wheels R
Since it is applied to the axle 22, the load applied to the guide device FE is minimized.

The rotating arms 16 or 33, 34 are held by the adjusting means 37, 38 in this operating state so as to maintain the angle β between the horizontal running surface of the road car and the rotating arms 33, 34. It

When the multi-way car MF travels in a zone in which a precise measuring device which may be damaged by the tire R on the rail 23 is mounted on the upper surface of the rail 23, in particular, as shown in FIG. In the configuration, as shown in FIG. 4, the rotating arm 3 of the guide device FE is used until the tire R is lifted sufficiently high from the rail 23.
An operating method is possible in which the angular positions of 3,34 are changed to α. Such a predetermined height adjustment is performed via hydraulic or mechanical adjusting means 37, 38 attached to the rotary arms 33, 34 and the rotary arm support 30. In the new adjustment position shown in FIG. 4, the rotary arms 33, 34 are fixed by shut-off valves. In this operating method, as will be described later, the multi-way car is supported, driven and braked only by the guide device FE.

The drive shaft 52 for driving the road surface running tire R is connected to a lifting device for the tire R via a connecting member (not shown) of the transmission gear 51. The transmission gear 51 receives the torque received from the car engine,
It is adapted to be transmitted to the universal joint shaft 54 via the shifting gear 53. This universal joint shaft is conventionally a transmission gear 51
Although not connected to the guide roller FE, the guide roller shafts 35 and 36 of the guide device FE are not connected to the universal joint shaft 5.
4 and the intermediate gear 56. In this way, the multi-way car MF is driven like a track running vehicle (see FIGS. 1 and 4).

That is, the guide rollers 12 and 14 are power-coupled to the drive unit of the vehicle MF to form the guide unit FE.
Can be made to function as a self-propelled orbital traveling mechanism.

If another universal joint shaft 55 is mechanically connected between the front axle 22 and the rear axle 22 with the intermediate gear 56, both, ie the front and the rear guide device FE simultaneously act as a drive device. .

Between the time when the pneumatic tire type wheels R bear the total weight of the multi-way car MF and the time when the guide device FE in the raised state of the pneumatic tire type wheels R bears the total weight of the multi-way car MF. It is also possible to distribute a part of the weight of the above to the pair of guide rollers 42 and 43 of the guide device FE and the other part to the pneumatic tire type wheel R. For this purpose, as already mentioned, the individual rotary arms 33, 34 can be moved to a predetermined angular position and fixed in that position via a shut-off valve.

The drive in this way of operation likewise takes place via pneumatic tire wheels R and via the guide roller pairs 42, 43 of at least one guide device FE. In this case, the transmission gear 51 uses the torque received from the car engine to drive the drive shaft 5 of the axle 22.
2 and via the shifting gear to the universal joint shaft 54. The universal joint shaft transmits the received torque to the guide roller pair 42, 43 via the intermediate gear 56.

In FIG. 3, the driving engine AM of the multi-way car MF functions as a driving device, and at least one of guide devices FE provided on each pneumatic tire type wheel via mechanical transmission means is shown. Guide roller pair 42,4
5 shows a multi-way car MF having a hydraulic pump 60, which is an example of being mechanically coupled with the hydraulic pump 3. This hydraulic pump is driven via an engine (not shown) of the multi-way car MF. The same components as those in FIGS. 1 and 3 are designated by the same reference numerals.
The hydraulic motor 62 provided in the guide device FE is the control device 61.
The hydraulic motor drives the guide roller shafts 35, 36 of at least one guide device FE.

Guide roller shaft 3 of the second guide device FE
The driving of 5, 36 is also possible in the same manner. This drive is performed by two separate hydraulic motors 62, as shown in FIG.
Alternatively, as shown in FIG. 4, it is performed by the universal joint shaft 55 provided between the first and second guide devices FE.

When the pair of guide rollers 42 and 43 are hydraulically driven, the driving force of the vehicle can be distributed. in this case,
The car engine drives the drive shaft 52 of the axle 22, and at the same time drives the hydraulic pump 60. Then, the hydraulic pump drives the hydraulic motor 62 provided in the guide device FE, which drives the pair of guide rollers 42, 43. When the second guide device FE is provided with two separate hydraulic motors 62, which are likewise connected to the hydraulic pump 60 and the control device 61, the hydraulic pump is a guide roller shaft 35, 36 of the second guide device FE. Will also drive.

From the above, the hydraulic pump 60 driven by the driving engine AM (see FIG. 1) of the multi-way car MF functions as a driving device, and the hydraulic transmission means 6 is used.
1 and 62, it is understood that it is motively connected to the guide roller pair 42, 43 of at least one of the guide devices FE provided on each pneumatic tire type wheel.

In any of the above-mentioned embodiments, a pair of guide rollers 42, 4 is formed by using a flange joint (not shown).
If 3 is replaced, it can be adapted to different track widths of the track SW. The structure of the guide wheel that can be flanged is
Depending on the depth of pull-in, that is, the extent to which the length from the flange surface to the running surface changes, by replacing only the guide wheel, the drive shaft can be left in its original state, and it can be operated on different track widths such as standard width track and narrow track. You can

When the multi-way car travels on a wide track, it may be necessary to replace the guide roller shafts 35 and 36 of the guide device FE depending on circumstances.

The braking devices 64 and 65 are the guide roller pair 4
The guide device F cooperates with the braking discs BS provided in Nos. 2 and 43.
The vehicle can also be braked when E provides full or partial drive for the multi-way car MF. In this way, the guide roller pair 4 of the guide device FE is
The provision of the braking device BS in the Nos. 2 and 43 is not limited to the above example, and is the same in the next example.

In particular, since the rotary arm is rotatably attached to the drive shaft, the rotary arm forms one vibration system together with the pneumatic tire type wheel, and vibrations due to unevenness of the ground or traveling and braking motions are driven. It is alleviated by the shock absorbers 24, 25 provided on the shaft.

Another embodiment of the present invention is shown in FIGS.
Shown in

The illustrated multi-way car MF has one guide device FE for each of the front tire and the rear tire R. The guide device FE can be rotated from the retracted position to the first operating position and the second operating position by means of the adjusting member 17 depicted as two piston / cylinder devices. Therefore, also in this example, the guide device FE
As the fixing means provided for fixing the rotating arm 16 of the above, an adjusting member that operates hydraulically, electromagnetically or mechanically is adopted.

The tire R is driven via the universal joint shaft 70 connected to the drive unit of the vehicle MF. In this case, the reversing gear 71 is attached to the universal joint shaft.

In the guide device FE, two guide rollers 12, 14 are provided on the front and rear tires R. The guide rollers 12 and 14 are attached to a cross beam 72 (see FIG. 7) of the guide device FE.
Extend substantially parallel to the axle 22 (see FIG. 6) supporting the tire R.

Further, as shown in FIG. 6, two rotary arms 16 are provided, one side of the rotary arms is rotatably attached to the vehicle body MF, and the other side thereof is a transverse beam 72 arranged so as to lie. It is fixed to.

One side of the adjusting member 17 is pin-connected to the vehicle body MF, and the other side is pin-connected at a position on the rotary arm 16 which is displaced from the cross beam 72 to a predetermined position. It is possible to rotate from a retracted position near the vehicle body to a first operating position and a second operating position. In this case, the adjusting member 17 is operated hydraulically. The guide device FE can be adapted to an arbitrary track width of the track SW by replacing the guide rollers 13, 14 and 42, 43 provided in the guide device FE.

The guide rollers 12 and 14 are rotatably mounted on the shaft 73. The shafts 73 (see FIG. 7) of the guide rollers 12 and 14 are fixed to the horizontal beam 72 from each side of the horizontal beam 72. The shaft 73 is axially expandable and contractable in the cross beam 72, and the guide device FE can be easily adapted to different track widths.

The guide rollers 12 and 14 are equipped with a friction drum 74. The friction drum is concentrically attached outside the guide rollers 12 and 14. The friction drum 74 is brought into contact with the friction tire so that it can be driven by the driving tire R of the multi-way car MF.

The cross girder 72 supported by the rotating arm 16 is lifted as the piston rod of the adjusting member 17 enters and is displaced to its retracted position. In this case, the rotating arm 16 moves upward and the guide rollers 12, 14
Are removed from the rails of the track SW, and the multi-way car MF becomes suitable for running on the road surface (not shown).

By the opposite movement of the piston rod of the adjusting member 17, the guide device FE is first moved from the retracted position to the first operating position. That is, at that time, the multi-way car MF has a track SW having a standard width track as shown in FIG.
On the rails.

FIG. 9 shows that the shaft 73 of the guide rollers 12 and 14 is supported in the cross beam 72 and the guide rollers 12 and 14 are
14 is an example of a structure in which 14 can be pulled in horizontally and extended. At the inner end of each shaft 73, a piston 81 that is displaced within the cross beam 72 is formed, and from a pressure source 82 to a control device 83 such as a control valve, a central oil supply pipe 84 to a piston chamber 85.
Pressure oil is introduced into the control unit 8 from the pressure source 86.
The pressure oil is introduced into the rod chamber of the spring box 88 via 7. The protruding body 90 is retracted by the elastic force of the spring 89, and the guide roller 14 projects as shown in the figure. When the piston 81 is displaced so as to have the track width of the standard width track, the control device 87 depressurizes the spring box 88, and the claw body 90 projects due to the elastic force of the spring 89 and engages with the inner notch 91 provided on the shaft 73. There is axis 7
Constrain the displacement of 3. Conversely, when trying to adapt to a narrow track, pressure oil is introduced from the left and right oil supply pipes 84 into the piston chambers 92, 93 via the control device 83, and the pawl 90 is meshed with the outer notch 94. .

FIG. 10 shows an example in which the guide rollers 12 and 14 have different retracting and projecting structures. When the gear 96 is rotated via the gear 97 by the drive source such as the motor 95, the screw bar 98 also rotates, and the both shafts 73 can be displaced by the turnbuckle action exhibited by the rotation of the left and right reverse screw bars. You can do it. Reference numeral 99 is a stopper fixed to the inner end of the shaft 73, which prevents the guide roller 14 from overhanging.

When the vehicle MF travels on the narrow track SW, the shaft 73, together with the guide rollers 12 and 14 and the friction drum 74, is moved inward by a predetermined amount before being displaced from the retracted position to the operating position. Move. As a result, the guide rollers 12 and 14 have the width of the narrow track SW to travel.

The guide device FE is deviated to the second operation position for traveling on the narrow track SW. 6 and 7
With reference to, the vehicle body MF is in the track SW at this operating position.
The tire R is lifted high from the rail 23 and the tire R is lowered onto the friction drum 74. Therefore, the total weight of the vehicle body is borne by the friction drum 74 and the guide rollers 12 and 14 through the friction drum 74 in accordance with the amount of division. As a result, the friction generated between the guide rollers 12 and 14 and the rail of the track SW becomes relatively small.

In this second operating position, for example, the reversing gear 71 is indispensable. This is because the reverse rotation of the rotation direction inevitably occurs between the tire R and the friction drum 74 in both traveling directions in every operation. This means that, as shown in FIG. 6, the tire R and the guide roller 1
This is apparent by the arrows in 2, 14 which indicate the direction of rotation.

As can be seen from the above description, the pneumatic tired wheel of a multi-way car can be changed to any height on the rail. Therefore, it becomes possible to adapt the multi-way car to all trajectories actually used. When the pneumatic tire type wheel is removed from the drive, the drive is performed only through the guide roller. In this running condition, the measuring device arranged directly adjacent to the rail surface is not damaged by the pneumatic tire wheels.

That is, the guide device according to the present invention enables the multi-way car to be quickly and sufficiently adapted in any operation without any problem.
