Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is applicable to a new transportation system called a guideway system in which vehicles run along guide walls erected on both sides or one side of a running track. Closed to the running gear.

(Prior art) In the above-mentioned guideway system, the vehicle travels along a guide wall erected on the side of a flat running track. It has a traveling device equipped with a steering device.

Conventionally, as shown in FIGS. 5 and 6, this traveling device includes a bogie frame 3, one end of which is attached to a bracket 2 provided at the bottom of a vehicle body 1 so as to be rotatable in the vertical direction, and an air spring 4. A knack arm 8 supported by a shock absorber 5 and connected to the phase n by a tie 7 to the end of an axle 6 provided on the bogie frame 3 is pivoted by a king pin 9, so that the right running wheel 10 can be moved from side to side. It is rotatably provided.

On the other hand, a guide wheel support arm 11 is provided on the bogie frame 3 so as to be rotatable in the width direction, and guide wheels 13 are attached to both ends of a guide wheel frame 12 supported by the guide wheel support arm 11. A connecting rod 14 provided on the guide wheel frame 12
is connected to a rotating lever 16 provided on the bogie frame 3 by a pivot 15 so as to be rotatable left and right, and furthermore, the rotating lever 16 and the knuckle arm 8 are connected by a steering rod 17.

By #ll centering in this way, the guide wheel 13 rolls along the guide wall 19 on the side of the running track 18, and the guide wheel frame 12 moves left and right according to the curve of the running track 18, and this movement The connecting rod 14 rotates the rotary lever 16 about the pivot shaft 15, and this rotation is transmitted to the knuckle arm 8 via the steering rod 17 to steer the traveling wheel 10.

(Problem to be Solved by the Invention) However, in the above configuration, the guide wheel arm that supports the guide wheel frame that moves left and right is rotatably attached to the guide wheel frame and the truck frame by pins, so the pin There was a problem that the mounting holes were worn and loose.

[Means for solving problems]

In order to solve the above problems, the present invention provides running wheels that run on a running track and running 1! In a guide rail car equipped with a guide wheel that rolls along a guide wall erected on the side of a road, a guide wheel arm that supports the guide wheel is provided with a plate spring so as to be movable in the width direction of the vehicle body. It is characterized by its support.

〔Example〕

An embodiment of the present invention will be described based on FIGS. 1 and 2.

The traveling device according to the present invention supports the central upper part of an axle 22 with an upper arm 21 which is attached to a bracket 20 fixed to the lower part of a vehicle body 1 so as to be rotatable in the vertical direction.
The lower arms 24 rotatably attached to the axle 22 support the lower sides of the axle 22, the axle 22 and the vehicle body 1 are supported by air springs 25, and the knuckle arms are interconnected to the ends of the axle 22 by tie rods 26. 27 is pivotally connected by a gearing bin (not shown), and left and right running wheels 28 are rotatably provided.

Then, two leaf springs 31 and 31 are respectively fixed to the left brackets 30 and 30 of the bogie frame 29 provided on the axle 22 with the bracket 30 sandwiched between the poles 1 to 32.
A mounting bracket 33 is provided at the other end, and the mounting bracket 3
The guide wheel frame 35 is supported rotatably left and right by the pin 34 inserted in the guide wheel support frame 35, the guide wheels 36 are attached to both ends of the guide wheel support frame 35, and the connecting rod 37 provided on the guide wheel frame 35 is connected to the bogie frame 29. It is connected by a pivot 38 to a rotating lever 39 which is provided so as to be rotatable left and right, and further, the rotating lever 39 and the knuckle arm 27 are connected by a steering rod 40.

With this configuration, even if the guide wheel 36 rolls along the guide wall 19 on the side of the running track 18 and the guide wheel frame 35 moves left and right according to the curve of the running track 18, Since the guide wheel frame 35 is supported by the leaf spring 31, the wear portion is reduced by half compared to the conventional support by the guide wheel support arm. Furthermore, the movement of the guide wheel frame 35 generates a restoring force in the leaf spring 31, so that straight-line stability is improved.

3 and 4 respectively show other embodiments of the present invention. In the one shown in FIG. The guide wheel frame 35 is supported by sandwiching the bracket 41 between two plate springs 31 and 31 fixed with bolts 32 and fixing them with bolts 42.

Figure 4 shows one leaf spring 37 attached to the bracket 3 of the bogie frame 29.
0 and the bracket 41 of the guide wheel frame 35 to support the guide wheel frame 35. By configuring the guide wheel frame 35 as in both of the above embodiments, there is no wear part even if the guide wheel frame 35 moves. , no looseness occurs.

(Effects of the Invention) As described above, the present invention provides a guide wheel frame that supports a guide wheel that rolls along a guide wall erected on the side of a traveling Fll road by a plate spring on a bogie frame or axle in the width direction. Since the guide wheel support arm is movably supported, there are fewer parts that wear out compared to the conventional guide wheel support arm, which prevents the occurrence of wobbling.Also, restoring force is generated in the leaf spring, improving straight-line stability. improves.
