Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a track vehicle that travels on a track with a rubber tire type traveling wheel.
[0002]
[Prior art]
As shown in FIGS. 9 to 11, the track vehicle normally has a plurality of unit vehicles M... Adjacent to each other, relative rotational movement (rolling) around the horizontal axis in the front-rear direction, and relative movement around the horizontal axis in the left-right direction. Rotating motion (front-rear rotation = pitching) and rotational movement about the axis X1 perpendicular to the trajectory (left-right rotation = yawing) are connected and configured.
[0003]
Each unit vehicle M is composed of a vehicle body 4 which is a box portion for accommodating passengers on a front and rear carriages 3 and 3 each having a pair of left and right traveling wheels 1 and 1 and an axle 2 of rubber tires. (For example, a swivel bearing) 6 is mounted.
[0004]
In addition, a pair of left and right (a total of four) guide wheels 7 are provided laterally on the front and rear sides of each of the unit vehicles M, and the guide wheels 7 are in contact with the guide surface G1 of the track G. Thus, the steering operation force is applied to the trolleys 3 and 3 at the curved portion and branching portion of the track (guideway) G, and the trolleys 3 and 3 rotate around the rotation axis X2.
[0005]
That is, in the conventional track vehicle, the steering operation of each unit vehicle M... Is performed by rotating the carriage 3 (axle 2) relative to the vehicle body 4 around the rotation axis X2 (steering rotation). .
[0006]
[Problems to be solved by the invention]
However, according to this configuration, since it is necessary to provide the turning mechanism 6 for rotating the steering at the coupling portion between the carriage 3 and the vehicle body 4 in each unit vehicle M, the turning mechanism 6 and the guide mechanism (guide) are provided on the carriage 3. Wheel 7 ... its accessory parts), suspension mechanism 5 and axle 2 are concentrated, so that the structure of the carriage becomes complicated and large.
[0007]
For this reason, the degree of freedom of design is reduced, the equipment cost is high, and the maintenance is troublesome.
[0008]
Therefore, the present invention provides a track vehicle in which a turning mechanism for rotating a steering wheel is separated from a carriage, and the carriage structure can be simplified and miniaturized.
[0009]
[Means for Solving the Problems]
The invention of claim 1 has the following requirements.
[0010]
(A) 1 axles by running wheels on one unit vehicle traveling on the track is, with respect to the vehicle body, that is provided with structure that does not pivot vertical Jikuma comparatively to orbit.
[0011]
(B) The adjacent unit vehicles are connected to each other in a state where they can be rotated around a steering axis perpendicular to the track via a connecting portion installed between the vehicles, the track-side guide surface, and the guide surface Each unit vehicle is configured to perform a steering operation by relatively rotating around the steering shaft by a steering operation force received from a guide wheel on the unit vehicle that rolls in contact with the wheel .
[0012]
(C) A unit vehicle is constructed in which adjacent unit vehicles are connected in a state where relative rotational motion about the horizontal axis in the left-right direction is restricted and can stand on their own, and the adjacent unit vehicles are arranged around the horizontal axis in the left-right direction. To be connected in a state where relative rotational movement can be performed.
[0013]
A second aspect of the present invention, in the configuration of claim 1 is intended axle dolly guide wheel attached was found provided.
[0014]
According to a third aspect of the present invention, in the configuration of the first aspect, the vehicle body is provided with guide wheels.
[0015]
According to the above configuration, the steering operation force received from the track-side guide surface and the vehicle-side guide wheel is transmitted from the carriage to the vehicle body (in the case of claim 2 ) or directly applied to the vehicle body (in the case of claim 3 ). ), The rotational force around the steering shaft (axis perpendicular to the track) at the connecting portion between the adjacent unit vehicles acts on the entire unit vehicle.
[0016]
Here, since each unit vehicle has a single-shaft structure with one axle, the entire vehicle is smoothly rotated by steering and the steering operation is performed smoothly.
[0017]
With this configuration, the turning mechanism for rotating the steering may be separated from the coupling portion between the bogie (axle) and the vehicle body in each unit vehicle and provided at the coupling portion between the unit vehicles. Concentration of the turning mechanism, guide mechanism, and axle) can be avoided. For this reason, the cart structure is simplified and miniaturized, and the degree of freedom in design is increased.
[0018]
Further, since the axle does not turn with respect to the vehicle body, the configuration of the propeller shaft that connects the driving drive motor and the drive axle provided on the vehicle body is usually simplified.
[0019]
By the way, in the case where each unit vehicle has a single-shaft structure as described above, if the adjacent unit vehicles are connected to each other so as to be able to rotate back and forth as in the past, the unit vehicles are independent (the ability to travel independently). In particular, when traveling on the slopes of ascending and descending, there is a possibility that the unit vehicle may be bent into a V-shape or an inverted V-shape at the connecting portion to hinder stable running.
[0020]
In this regard, according to the above configuration, one unit vehicle that can stand on its own is constituted by two adjacent unit vehicles, and a forward / backward rotating action is performed at the connecting portion between the unit vehicles. A stable running function is ensured in each part of the track.
[0021]
Further, according to the configuration of the third aspect , since the steering operation force acts directly on the vehicle body, there is no transmission loss of the steering operation force as compared with the case where the configuration of transmitting from the carriage to the vehicle body as in the second aspect is taken. Therefore, it is not necessary to apply structural ingenuity to reduce this loss.
[0022]
For this reason, the facility cost can be reduced and the vehicle can be easily increased in size and weight.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS.
[0024]
Here, an example of a four-car train vehicle in which four unit vehicles V... Are connected is illustrated.
[0025]
1st Embodiment (refer FIGS. 1-7)
Each unit vehicle V is configured as a single-shaft vehicle in which a vehicle body 14 is mounted via a suspension mechanism 15 on a single carriage 13 having a pair of left and right traveling wheels 11, 11 of rubber tire type and one axle 12. Has been.
[0026]
Here, unlike the conventional unit vehicle M shown in FIGS. 9 to 11, there is no turning mechanism between the carriage 13 (axle 12) and the vehicle body 14, and the steering rotational movement around the axis perpendicular to the track G is The configuration is not performed.
[0027]
16 is a pair of left and right (four in total) guide wheels provided on both the front and rear sides of the carriage 13, and the guide wheels 16 are in contact with the guide surface G1 of the track G to roll. A force is applied, and this steering operation force is transmitted to the vehicle body 14.
[0028]
The unit vehicles V are connected to each other so as to be capable of steering rotation around a steering axis O perpendicular to the track G, and the steering operation force is applied to the entire unit vehicle V around the steering axis O. Acts as a force.
[0029]
In this case, since the unit vehicle V has a single shaft structure with one axle 12 as described above, unlike the two shaft structure, the entire unit vehicle V performs a steering operation without difficulty due to the rotational force.
[0030]
In addition, although not shown in figure, each unit vehicle V ... is connected in the state which can be rolled.
[0031]
In this manner, the turning mechanism for rotating the steering is separated from the coupling portion of the carriage 13 and the vehicle body 14 in the unit vehicle V, and the steering operation is performed around the steering shaft O arranged at the coupling portion of the unit vehicles. Therefore, the cart structure is much simpler and smaller than the conventional track vehicles shown in FIGS.
[0032]
The structure of the connection part of unit vehicles V and V is explained in full detail with reference to FIGS.
[0033]
Two adjacent unit vehicles (two on the front side and two on the rear side) V and V are slewing bearings between connecting brackets 17 and 18 projecting from the lower surface of each vehicle body 14 as shown in FIGS. 19 and 19 are interposed, and a relative rotation (steering rotation) is possible around the steering shaft O which is the center of the slewing bearing 19, and a forward / backward rotation around the horizontal horizontal axis is restricted (blocked). ing.
[0034]
In this way, two adjacent unit vehicles V, V are connected in a state of being integrated in the sense that they do not relatively rotate back and forth, so that they can stand on their own by the traveling wheels 11 (the mutual connection). The unit vehicle U is configured such that it cannot be folded into a V-shape or an inverted V-shape.
[0035]
And these unit vehicles U and U are as shown in FIGS.
(A) A vehicle body side bracket 20 and an intermediate bracket 21 projecting from the lower surface of one vehicle body are connected to each other around the steering shaft O via swing bearings 22 and 22 so as to be relatively rotatable.
By (b) the other of the vehicle body lower surface and the vehicle body-side bracket 23 projecting from the intermediate bracket 21 is pivotally connected to the horizontal axis Y around a left-right direction, a steerable rotate about the steering axis O, and Are connected in a state in which they can pivot back and forth.
[0036]
Thus, each unit vehicle V... Can travel without being bent even though it has a single-shaft structure, and in the track gradient portion as shown in FIG. The entire vehicle is configured to be able to travel stably.
[0037]
Second embodiment (see FIG. 8)
Only differences from the first embodiment will be described.
[0038]
In the first embodiment, the guide wheels 16 are provided on the carriage 13 of each unit vehicle V, whereas in the second embodiment, the guide wheels 16 are provided on the vehicle body 14.
[0039]
In this way, the steering operation force by the guide surface G1 and the guide wheels 16 acts directly on the vehicle body 14 not via the carriage 13 as in the first embodiment, so that the steering is compared with the first embodiment. There is no transmission loss of the operating force, and there is no need to make structural measures such as adding a booster mechanism to reduce this loss.
[0040]
For this reason, the cost of the guide mechanism can be reduced, and the steering force transmitted to the vehicle is increased, so that it is possible to easily cope with an increase in size and weight of the vehicle.
[0041]
【The invention's effect】
As described above, according to the present invention, the turning mechanism for rotating the steering may be separated from the coupling portion between the bogie (axle) and the vehicle body in each unit vehicle and provided at the coupling portion between the unit vehicles. The structure of the carriage can be simplified and miniaturized by avoiding the concentration of the mechanisms (the turning mechanism, the guide mechanism, the suspension mechanism, and the axle). Thereby, the freedom degree of the design of a trolley | bogie part and by extension, the whole vehicle increases, installation cost is low, and a maintenance becomes easy.
[0042]
In addition, since the axle does not turn with respect to the vehicle body, the configuration of the propeller shaft that connects the driving axle and the driving axle provided on the vehicle body is usually simplified.
[0043]
Furthermore , since two unit vehicles adjacent to each other constitute one unit vehicle that can stand on its own, and the connecting part between the unit vehicles is operated to rotate back and forth, stable running on each part of the track including the gradient part is possible. Function is secured.
[0044]
In addition , according to the invention of claim 3 , since the steering operation force directly acts on the vehicle body, the transmission of the steering operation force is compared with the case where the structure for transmitting from the carriage to the vehicle body as in the invention of claim 2 is adopted. There is no loss, and it is not necessary to devise structural measures to reduce this loss.
[0045]
For this reason, the facility cost can be reduced and the vehicle can be easily increased in size and weight.
