JPS5843490Y2 - Improved bogie of bolsterless type bogie car - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to an improvement of a bogie for a bolster-less type bogie, and more particularly to a bogie that can be easily attached to a bogie frame.

In a bogie car, as a device for towing the car body when the bogie is driven once, there is a swing pillow, or a bolster, which is pivotally mounted on the bogie frame, and a bogie frame that supports the left and right ends of this bolster in a slidable manner. A traction device comprising side supports provided on the left and right sides of a vehicle and a bolster anchor provided as a traction means between the bolster and the vehicle body is widely known in the art.

This type of traction device uses relatively heavy bolsters and is relatively complex in construction.

Therefore, such a towing device cannot be said to be preferable in terms of vehicle weight reduction and maintenance.

In recent years, various types of so-called bolster-less type bogie vehicle traction devices, which do not include a bolster, have been developed as alternatives to such traction devices.

In such a traction device, a leaf spring, a cushioning rubber member, a link, or the like is used as the traction means, and these traction means connect the bogie and the vehicle body to tow the vehicle body.

This type of traction device is characterized in that the traction means body as described above is configured to compensate for relative displacements in the longitudinal and lateral directions between the bogie and the vehicle body as well as rotational displacements therebetween. It is something.

Such a traction device is installed in the middle of the trolley,
The left and right air splashes are arranged independently.

Therefore, when installing the vehicle body on the bogie, the traction device and the left and right air springs must be individually positioned and attached to the vehicle body, making the installation process extremely complicated.

In particular, the work of installing air springs is difficult because they tend to move easily due to their characteristics and are difficult to position.

SUMMARY OF THE INVENTION An object of the present invention is to provide an improved bogie for a bolster-less bogie that allows the work to be easily done when attaching a car body to a bogie frame.

In the improved bogie according to the present invention, a common top plate is attached to the left and right air springs and the traction sub-device arranged on the bogie frame, and a positioning device is provided for positioning this top plate with respect to the car body. .

According to the present invention, by attaching a common top plate to the left and right air springs and the traction device, the relative positions of the left and right air springs and the traction device are predetermined.
By positioning only the top plate relative to the car body and attaching the top plate to the car body, the work of installing the car body onto the bogie frame is completed.

Therefore, the complexity of the conventional installation work can be greatly reduced.

Next, an embodiment of the improved trolley according to the present invention will be described with reference to the accompanying drawings.

In FIGS. 1 and 2, reference numeral 1 indicates a truck frame, and the truck frame 1 has side beams 2 and cross beams 3.

Each side beam 2 of the truck frame 1 is provided with a mounting seat 4 for an air spring, and an air spring 5 is mounted on the mounting seat 4.

The horizontal beam 3 of the truck frame 1 is provided with a mounting seat 6 for a traction device.

The traction device 7 is composed of a reverse gate-shaped leaf spring 8, and the leaf spring 8 is rotatably mounted on the mounting seat 6.

Each air spring 5 is provided with an upper plate 9 at its top, and a pair of leaf spring mounting members 10 are provided between the tops of both legs of the inverted portal shape of the leaf spring 8.

As shown in FIG. 2, a common top plate 11 is attached to the upper plate 9 of the air spring 5 and the leaf spring mounting member 10, and the relative positions of the left and right air springs and the auxiliary device are determined by this. Ru.

Note that in this embodiment, the top plate 11 is attached to the mounting member 10.
It is fixed to the upper plate 9 with bolts or the like, and is attached to the upper plate 9 in such a manner that the protrusion 12 of the upper plate 9 is fitted into the recess 17 of the top plate 11.

The vehicle body 13 is mounted on the bogie frame 1 by fixing the top plate 11 to the bottom of the vehicle body 13 with bolts 14 or the like.

In this installation work, in order to position the top plate 11 with respect to the vehicle body, a positioning stud 15 is placed in the center of the top plate 11.
A positioning hole 16 for receiving the stand 15 is provided at the bottom of the vehicle body 13.

That is, in this embodiment, a positioning device for positioning the top plate 11 with respect to the vehicle body is constituted by the studs 15 and the holes 16.

According to the present invention, a common top plate is attached to the left and right air springs and the traction sub-device arranged on the bogie frame, and the relative positions of the left and right air springs and the traction sub-device are determined by this. Therefore, the car body can be attached to the bogie by positioning only the top plate with respect to the car body and fixing the top plate to the car body.

Therefore, the complexity of attaching the left and right air springs and the auxiliary device to the vehicle body individually, as in the conventional mounting process, is eliminated.
