Field of the Invention The present invention relates to a low-floor articulated railway vehicle used as a transport system compatible with barrier-free technology, and in particular, does not require major modification of maintenance equipment. The present invention relates to a low-floor articulated vehicle capable of responding to the following. 2. Description of the Related Art FIGS. 3A and 3B show an example of a conventional low floor articulated vehicle, wherein FIG. 3A is a plan view and FIG. 3B is a front view. FIG. 4 is a schematic structural view showing a part of the conventional articulated vehicle in an enlarged manner. FIG. 4A is a plan view, and FIG. 4B is a front view. In this vehicle, a vehicle A in front and a vehicle B in rear are C
It is connected by car. Vehicle A has a trolley D only at the front end, vehicle B has a trolley D only at the rear end, and vehicles A and B are trolleys E provided on vehicle C.
As a result, the vehicle body is held horizontally. In other words, when the vehicle is a three-body, two-connected vehicle, they are balanced on the trolley provided for each vehicle, and the vehicle is kept horizontal with the balance maintained. As described above, the conventional low-floor type vehicle has a three-body, two-joint structure, a two-axis power bogie (motor bogie) with bolsters (pillows) at both ends, and a bolsterless independent wheel-attached bogie (trailer bogie) at the center. ) Are arranged. [0005] In the case of the above conventional configuration,
Each power bogie D arranged in A / B car (A car or B car)
Has wheels W provided on both left and right ends of each of two axles, and a motor is arranged between the wheels. The trolley of the power bogie is attached to the bolster F of the vehicle body, and the bogie and the vehicle body can be freely turned via a center pin G arranged in a vertical direction. Therefore,
The part of the power trolley could not be reduced to a low floor. As described above, in the conventional configuration, in the A / B vehicle, a portion corresponding to the power bogie, that is, approximately 30% of the passenger compartment has a high floor, and a low floor of 100% cannot be achieved. [0006] On the other hand, some vehicles have realized a 100% low floor, but in such vehicles, a special power bogie is used in order to lower the power bogie portion. That is, it is necessary to hold the left and right wheels of the power bogie independently. Therefore, a conventional two-axis bogie having a proven track record cannot be used. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a main object of the present invention is to realize a barrier-free by realizing a 100% low floor while using a twin-screw bogie generally used at present. It is an object of the present invention to provide a low-floor articulated vehicle suitable for a vehicle. In order to achieve the above object, a low floor articulated vehicle according to the present invention has a cab body independent of a cabin body and is provided at both front and rear ends.

BRIEF DESCRIPTION OF THE DRAWINGS It is a schematic structure figure of one Example of the low floor articulated vehicle of this invention, (a) is a top view and (b) is a front view. The vehicle in the illustrated example is a five-body, four-connected vehicle, and is used as a tram. The low-floor articulated vehicle of this embodiment has a structure in which the A / B vehicle of the conventional three-body two-article vehicle shown in FIG. 3 is separated into a cab body 1 and an end passenger cabin body 2. . That is, A
/ B car's two-axis power bogie D (4) end side (cab side)
However, it is independent from the guest room. As a result, the low floor articulated vehicle of the present embodiment has a cab body 1, 1 disposed at each of the front and rear ends and an intermediate cabin body (corresponding to the C vehicle in FIG. 3) 3 disposed at the center. , This middle cabin body 3
End passenger cabin body 2 disposed between the vehicle and the cab body 1
Are connected. The cab body 1 and the intermediate cabin body 3 are
The length is sufficiently shorter than the end passenger cabin vehicle body 2, and the adjacent vehicle bodies are connected by a horizontal (and vertical) movable connection device 5 (6). At this time, in the present embodiment, the cab body 1 and the end passenger cabin body 2 are connected by a horizontally movable connecting device 5, and the connection between the end passenger cabin body 2 and the intermediate passenger car body 3 is
It is connected by a horizontal / vertical movable connection device 6. In addition,
Each vehicle is connected to a rubber cushion by a bellows-like rubber material H (FIG. 3). The cab body 1 is mounted on a two-axis trolley 4. FIG. 2 is a schematic structural view of an example of a two-axis power bogie 4 attached to the cab body 1, (a) is a plan view, (b) is a front view, and (c) is a side view. The two-shaft power bogie 4 has substantially the same configuration as a conventionally used two-shaft bogie.
That is, two axles along the vehicle width direction are arranged in parallel in the vehicle in the longitudinal direction, and wheels 7, 7 are attached to both ends of each axle. And these wheels 7
Is rotatable by a motor or the like disposed between wheels. The power truck 4 having such a configuration is attached to a lower portion of the cab body 1. At this time, as before, the pillow 9 of the carriage 4 may be attached to the pillow 8 of the vehicle body 1 and the trolley 4 may be pivotally attached to the vehicle body 1 with a center pin. It is preferable to mount the cart 4. That is, the bolster 9 and the center pin of the carriage 4 can be omitted. In this case, the body 1 is placed on the air spring 10 of the carriage 4.
Will be arranged. The reason why the pillow beam 9 and the center pin of the truck 4 can be omitted is as follows. That is, in this embodiment, the cab body 1 and the end passenger cabin body 2 are assembled by the horizontally movable connecting device 5, and the length of the cab body 1 is substantially equal to that of the power bogie 4 thereunder. Therefore, the cab body 1 and the power trolley 4 below the cab body 1 take the same movement during traveling. Therefore, the bogie 4 is relatively rotated (turned) with respect to the vehicle body 1 with the center pin so that only the bogie 4 can run independently as in the conventional case where the bogie is attached to a relatively long vehicle.
There is no reason to make it possible. That is, in this embodiment, since the same movement of the vehicle body 1 and the bogie 4 holding the vehicle body is possible, the vehicle body 1
The need for a center pin between the trolleys is eliminated, so that the trolley bolsters 9 are not required. Therefore, the underframe can be configured by using the body bolster 8 as the trolley bolster 9. As a result, the floor height of the driver's cab can be reduced by the height of the bogie pillow, and the lower part of the air spring is a driver's cab body which can handle 100% of the cabin while using the same bogie as before. The middle passenger cabin body 3 has the same configuration as the conventional C car shown in FIG. That is, the vehicle body is mounted on the bolsterless independent wheel accompanying truck. This independent wheel-attached truck is a conventionally known general one used for the C car. That is, wheels are rotatably held at four corners of the bogie. The left and right wheels are not held on the same axle but are held independently, and since they are accompanying trucks, the drive mechanism such as a motor is also omitted. In addition, since there is no pillow, the middle passenger cabin body can be configured on a low floor. The bogie 2 is not provided with a bogie, and the bogie 2 is held by trucks of a driver's cab body 1 and an intermediate cabin body 3 disposed before and after it. The driver's cab body 1 is provided with an auxiliary underframe 11 below the end underframe on the side passenger cabin body 2 side. The auxiliary underframe 11 is used for the end passenger cabin body 2.
Are arranged at substantially the same height as the underframe 12. The auxiliary underframe 11 of the driver's cab body 1 and one end underframe of the adjacent passenger cabin body 2 adjacent thereto are connected by the horizontally movable connecting device 5. Similarly, the other end frame of the end passenger cabin vehicle body 2 and the end frame of the intermediate passenger cabin vehicle body 3 adjacent thereto are connected by a horizontal / vertical movable connection device 6. In this embodiment, the horizontally movable connecting device 5 between the cab body 1 and the end passenger cabin body 2 uses the first connecting arm 51 from one vehicle (cab body) 1 side to the other vehicle (cab body). The second connecting arm 52 is arranged so as to protrude from the other vehicle (the end cabin vehicle body) 2 toward the one vehicle (the cab body) 1 side. Then, one race of the horizontal bearing 53 is fixed to the projection of the first connecting arm 51, and the other race of the horizontal bearing 53 is fixed to the projection of the second connecting arm 52. Thereby, the two connecting arms 51 and 52 can be rotated in the horizontal plane via the horizontal bearing 53. In this embodiment, the horizontal / vertical movable connecting device 6 between the end passenger cabin body 2 and the intermediate cabin vehicle body 3 includes a first connecting arm 61 from one vehicle (intermediate cabin vehicle body) 3 side and the other. The vehicle (end passenger cabin body) 2 is arranged so as to protrude toward the
A connecting relay member 64 is rotatably held on the upper surface of the projecting portion of the connecting arm 61 via a horizontal bearing 63, and the second connecting arm 62 is attached to shaft portions 64 a, 64 a protruding to the left and right of the connecting relay member 64. The second connecting arm 62 is held rotatably.
Is fixed to the other vehicle 2 by welding. Alternatively, in the horizontal / vertical movable connecting device 6, the first connecting arm 61 on one vehicle 3 and the second connecting arm 62 on the other vehicle 2 rotate in a horizontal plane by a horizontal bearing 63. The second connecting arm 62 may be held so as to be rotatable in a vertical plane with respect to the other vehicle 2. In other words, the first connecting arm 61 is arranged to protrude from the one vehicle 3 toward the other vehicle 2, and the horizontal bearing 63 is fixed to the first connecting arm 61, and one race is fixed to the first connecting arm 61. By being fixed to the other race of the horizontal bearing 63, the horizontal bearing 63 is rotatably connected to the first connecting arm 61, and protrudes to the left and right ends on the other vehicle 2 side outward in the left-right direction to form a shaft. Second connecting arm 6 provided
2 and a bearing that rotatably holds the shaft of the second connecting arm 62 and that is bolted to the other vehicle 2. According to the low floor articulated vehicle of the above embodiment,
The entire area of the cabin except for the cab, that is, the entire area of the side passenger cabin body 2 and the intermediate cabin body 3 can be made 100% low. Therefore, it can be used as a transportation suitable for barrier-free use. By the way, in the connecting portion between the vehicles, the horizontal bearings 53 and 63 allow the vehicle to rotate in the horizontal direction, and the bearings allow the vehicle to rotate in the vertical direction, so that the vehicle can run smoothly. The low-floor articulated vehicle of the present invention is not limited to the configuration of the above-described embodiment, but can be changed as appropriate. For example, in the above-described embodiment, an example was described in which the cab body 1 at each end and the middle passenger cabin body 3 at the center were connected to each other via the end passenger cabin body 2 to form a five-vehicle four-connected vehicle. The numbers of the intermediate cabin vehicle bodies 3 and the end passenger cabin vehicle bodies 2 interposed between the cab vehicle bodies 1 and 1 can be appropriately changed. For example, one vehicle may be added to each vehicle, and the vehicle may have seven bodies and six articulated vehicles. In the above-described embodiment, the example in which the driver's cab body 1 and the side passenger cabin body 2 are connected by the horizontally movable connecting device 5 has been described. Similarly, the horizontal and vertical movable connection device 6 may be used for connection between the vehicle and the intermediate cabin body 3. As described above, according to the low-floor articulated vehicle of the present invention, almost the entire area of the passenger cabin is made to have a low floor while using a two-axis bogie bogie that has been used in the past. be able to.
Therefore, it can be used as a low floor articulated vehicle suitable for barrier-free use.
