Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bolsterless bogie guard device.

As shown in Fig. 1, a conventional bogie for a railway vehicle is equipped with a center pin receiver d on an underframe C mounted on an axle with an axle spring a, and a support beam e is attached to the center pin receiver d. At the same time, a center pin fk protruding from the body is fitted, a side support gk is interposed between the underframe C and the pillow e, and an air spring hi is interposed on the upper surface of the pillow e to mount the vehicle body i. It has a structure in which the pillow e and the vehicle body i are connected by a bolster-anchor j. For example, when the vehicle is displaced vertically and horizontally, the air spring h and the bolster-anchor j act, and the longitudinal displacement of the vehicle is controlled by the bolster. - Only the anchor j acts, and the rotational displacement of the vehicle is caused by the center pin f and the side supports g.

However, as mentioned above, in conventional trolleys of this type,
Since there are many components, it is not possible to reduce the weight of the vehicle, maintenance and inspection are troublesome, and the bogie portion occupies a large amount of space, which reduces the effective space of the vehicle body.

This invention was made with the intention of solving the above problem, and the center pin receiver is supported by laminated rubber attached to the bogie frame cross beam, and the center pin receiver is
By fitting the center pin that protrudes from the car's head and support beams, the vertical, horizontal, and longitudinal displacement of the vehicle can all be made possible by laminated rubber, completing the tasks that were previously handled by the side supports and bolster anchors of conventional bogies. The entire vehicle can be operated by a single force using the air spring and the core plate device of this invention, which makes it possible to reduce the weight of the vehicle, facilitate inspection and maintenance, and increase the effective space of the vehicle body. It is an object of the present invention to provide a bolster-less bogie guard device that can provide excellent effects such as:

Embodiments of the present invention will be described in detail below with reference to FIGS. 2 and 3.

The drawing shows the main parts of a bolsterless bogie fully equipped with the core plate device of the present invention. Two sets of laminated rubber 3, 3, . . . are attached, and the center pin receiver 2 is supported by these laminated rubber 3, 3, . In this case, the center pin receiver 2 is a cylindrical pin receiver that opens in the vertical direction, and has a base 2a, vertical mounting pieces 2b, 2b that protrude outward from the opposing side surfaces of the base 1J2a, and both mounting pieces 2b. , 2b, and consists of an upper reinforcing piece 2C1, a lower reinforcing piece 2d, and a stopper rubber attachment piece 2e, which are connected in a substantially straight line to the upper and lower ends and the tip edge of the stopper rubber attachment piece 2e.

A stopper rubber 5 is fixed to the outer surface of 2e with a fixing member 4 such as a bolt or nut. In addition, center pin receiver 2
In case of support, the tip surfaces of each laminated rubber 3 attached to the opposing inner side surfaces of the bogie frame structure 91 are brought into contact with the mounting piece 2b of the center pin receiver 2, and both compressed laminated rubbers facing each other are The rubber parts 3, 3 are fixed to each other using fixing devices 6 such as bolts and nuts.

(5) The center pin 8 protruding from the lower surface of the vehicle body support 7 is rotatably fitted into the base 2a of the center pin receiver 2 supported as described above.

According to the core plate device of the present invention configured as described above,
The center pin receiver 2 is supported by the laminated rubber 3, 3... attached to the inner opposing parts of the bogie frame cross beam IK.
are supported, that is, the bogie frame cross beam 1 and the center pin receiver 2
Since the laminated rubber 3 is compressed and assembled between the mounting piece 2b and the mounting piece 2b, the spring constant in the longitudinal direction of the vehicle can be completely stiff, and the spring constant in the horizontal and vertical directions can be made soft.
According to the center plate device of the present invention, even if a large-diameter special air spring (not shown) is used for a bolster-less truck, the left and right laminated rubber 3s that support the center pin receiver 2 can overcome the lack of lateral rigidity. , 3..., and can achieve the same pure lateral rigidity as conventional bogies of this type. Therefore, in the pure lateral direction, the soft shearing properties of the laminated rubber 3, 3... can be utilized, so even if all air springs with soft lateral stiffness are used to reduce rotational resistance, lateral vibration will not occur. In contrast, it has the effect of providing the same pure lateral support rigidity as conventional bogies of this type, and separation and connection between the car body and bogie can be done by lifting the conventional air spring bogie directly connected to the car body. There is also an advantage in terms of maintenance.

As explained above, according to the core plate device of the present invention,
The center pin receiver is supported by the laminated rubber cut into the bogie frame cross beam, and by fully fitting the center pin protruding from the car body into the center pin receiver, the upper and lower parts of the vehicle can be adjusted.
Lateral and longitudinal displacements are all possible using laminated rubber, eliminating the need for side supports, bolster anchors, pillows, etc. in conventional bogies of this type, and moreover, air springs do all the work that was done by side supports and bolster anchors. Since this can be done by the core plate device of this invention, it is possible to significantly reduce the weight of the vehicle, and it also has advantages such as easy inspection and maintenance, and the ability to widen the effective space of the vehicle body. It has a significant effect and its utility value is remarkable.
