Problems solved by technology

[0013] In addition, there is a problem that the movement of the guide wheel due to the unevenness of the guide rail is directly transmitted to the rubber tire, which affects the running of the rubber tire. Since the running of the rubber tire is unstable, it is necessary to improve the accuracy of the guide rail.

Embodiment approach 1

[0064] based on figure 1 and figure 2 A guide rail vehicle using the bogie according to the first embodiment of the present invention will be described. Such as figure 1 As shown, in the new traffic system, guide rails 10 are arranged along the track T on both sides of the track T of the traveling vehicle 12 . Two bogies 16 are equipped at the front and rear of each bogie vehicle. The bogie 16 is provided with a guide wheel 42 that is in contact with the rolling surface of the guide rail 10 and rolls, and the vehicle 12 travels on the track T under the guidance of the guide wheel 42 . figure 1 In , arrow a indicates the traveling direction of the vehicle 12 .

[0065] Alternatively, a guide rail may be provided at the center of the track T, and the guide wheels may roll in contact with both side surfaces of the track so as to sandwich the guide rail.

[0066] exist figure 2 In this case, a bogie 16 is attached to the lower surface of the vehicle body 14 via an air s...

Embodiment approach 2

[0087] based on image 3 A second embodiment of the present invention will be described. exist image 3 Among them, this embodiment is the same as the first embodiment except for the structure described below. That is, with respect to the rotation of the guide frame 36, a return rod 60 that provides a restoring force in the forward direction and a rotation damper 62 that suppresses violent rotation are attached to the beam rod 38 on the vehicle end side of the guide frame 36 via the connecting rods 64 and 66, and It is arranged side by side with the beam rod 38 .

[0088] The restoring rod 60 is a structure connected to a buffer mechanism composed of a spring element and a damping element, and provides force to the guide wheel 36 in a direction returning to a neutral posture, which puts the rubber tire 28 in a forward state (for example, refer to Japanese Patent Laying-Open No. 2 -210150 Bulletin). The rotation damper 62 is constituted by, for example, a conventionally kno...

Embodiment approach 3

[0094] based on Figure 4 A third embodiment of the present invention will be described. In the present embodiment, a manipulation mechanism 46 having a different structure than that of the first embodiment is employed. That is, the tie rod 50 of the steering mechanism 46 (similar to the first embodiment, it is disposed closer to the center side in the front-rear direction of the vehicle body than the drive shaft 24) is composed of split rods 86a and 86b divided into two parts at the center position in the axial direction. The rods 86a and 86b are rotatably connected to each other, and the connecting point is connected to a receiving portion 88 protruding from the beam rod 38 provided on the center side in the front-rear direction of the vehicle body.

[0095] Therefore, the rotational motion of the guide frame 36 is directly transmitted to the steering pins 26 of the left and right rubber tires 28 via the receiving portion 88 and the split levers 86a, 86b, whereby the rubber ...

Abstract

A bogie (16) for a guide rail system vehicle, wherein the bogie (16) is configured so that a load on a guide wheel is reduced and the bogie has increased durability obtained by increasing the strength of a bogie structure including a guide frame and achieves stable travel performance not affected by surface irregularity of a guide rail. A bogie (16) for a guide rail system vehicle, wherein the bogie is guided by guide wheels (42) in contact with and rolling on a guide rail (10) mounted along a travel path (T) and wherein rubber tires (28) are steered by a steering mechanism (46) interlocked with the guide wheels. The bogie (16) is provided with a guide frame (36) having a structure comprising two lateral beam members (38) mounted to the front and rear of a bogie structure, to opposite ends of which the guide wheels (42) are rollably mounted. The structure also comprises joint members (40) mounted between the two lateral beam members (38). The guide frame is pivotably supported by a circular or circular arc-shaped bearing (34) horizontally supported on non-pivotable portions (22, 23) of the bogie structure, the steering mechanism (46) is connected via a connecting rod (54) to the guide frame (36), and the rubber tires (28) are steered with the steering mechanism (46) operatively associated with movement of the guide frame (36).

Description

technical field [0001] The invention relates to a guide rail type vehicle bogie, which is connected with a guide rail arranged along a running track, and the vehicle runs on the running track through the movement of the guide wheels. Background technique [0002] Recently, a so-called new transportation system has been popularized, which uses rubber tires to run on dedicated tracks and carry out medium-volume transportation. The transport system mostly operates fully automatically without people, for example, it may also be the case with guide wheels guided by guide rails. [0003] It is known that, as a vehicle for a new traffic system, a bogie vehicle is equipped with four guide wheels, the two guide wheels of the front bogie are connected with the rubber tires of the front bogie via the steering mechanism, and the two guide wheels of the rear bogie The wheels are connected with the rubber tires of the rear bogie through the steering mechanism, thus, the rubber tires of t...
