[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a mounting device for a driving gear device in a railway vehicle.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional mounting device of a gear device for a railway vehicle includes a bracket 18 provided on a gear device 2 supported on an axle 26 and a bracket 19 projecting from a bogie frame 17. Are supported by hanging bolts 20. That is, a suspension pipe 21 is fitted on the suspension bolt 20, and the suspension pipe 21 is supported by a support member 22 protruding from the gear device 2, and a buffer is provided on both sides of the bolt holes provided in the brackets 18 and 19. The rubber 23, the liner adjusted to a required thickness and the washer 24 are interposed, the suspension bolt 20 is passed through, and the nut 25 is tightened.

[0003]

As described above, the conventional rail gear mounting device for a railway vehicle gearbox has a cushioning rubber, a liner,
Since it is configured by fastening with bolts and nuts with washers interposed, the number of components is large and the assembly work is complicated, and after the assembly is completed, loosen the nut again to adjust the height of the gear device and remove the liner. It was necessary to tighten the nut after adjusting and adjusting it, which took a lot of trouble. Further, the bogie frame requires a long protruding bracket, which increases the weight.

This invention eliminates the above-mentioned drawbacks of the conventional mounting device, and has a simple structure and a link type mounting device which can be easily mounted on a bogie frame and a gear device and the height of the gear device can be easily adjusted. Is provided.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, a mounting apparatus for a gear unit for a railway vehicle according to the present invention is provided with a facing device.
Has horizontal serration grooves on the surface,
Adjust the position and fix with bolts and nuts
Mounting section with serration mechanism consisting of
The Ru provided with truck frame side and the gear side. Then, both taken of
The connecting portions are linked by a connecting rod via a rubber bush joint.

[0006]

The bogie frame side and the gear unit are both mounted by a mounting portion having a serration mechanism. In particular, the bracket on the bogie frame side is omitted, so that the weight is reduced and the mounting of the mounting device is reduced. Height adjustment is easy and installation is easy. Further, since the upper and lower mounting portions are linked by a connecting rod via a rubber bush joint, the torsion generated due to the relative movement between the bogie and the axle is absorbed by the rubber bush, and the stress generated in the mounting portion is reduced. Can be alleviated.

[0007]

An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a mounting portion 5 having a serration mechanism to truck frame 1 side and the gear device 2 both provided, articulated rod via a rubber bush joint 4 between the support rod 11 which projects to the mounting portion 5 3 by means of the link connection.

Details of the mounting portion 5 and the rubber bush joint 4 are shown in plan views on the line AA in FIG. 1 and FIG.
3 will be described with reference to FIG.
The mounting portion 5 includes a bogie frame side serration member 6 and a connecting rod side serration member 7. The bogie frame side serration member 6 is attached to the side surface of the bogie frame 1 by welding or the like with the horizontal serrations 8 facing outward. a pair of right and left screw holes 13 for screwing the stud 9 is Ru set Ketea. On the other hand, the connecting rod side serration member 7 has a support rod 11 at the center.
The screw holes 13 are provided on the left and right sides of the support rod 11.
Long holes 12 of the pair of vertical is are only set corresponding to. The studs 9 are screwed into the screw holes 13, and the connecting rod side serration members 7 direct the serrations 8 in the horizontal direction toward the bogie side, and pass the studs 9 through the elongated holes 12 to any height position . adjusting engagement both serrations 8, to fix the nut 10 by only fastening flashing.

The rubber bush joint 4 is formed by passing a bolt 15 fitted with a rubber bush 14 into a bolt hole provided at an end of the supporting rod 11 of the mounting portion and an end of the connecting rod 3 and tightening a nut 16.

The mounting portion 5 and the rubber bush joint 4 on the gear device side have the same configuration as the mounting portion and the rubber bush joint on the bogie frame.

[0011] With the above configuration, when installing the mounting device,
In a state in which meshing removing the serration 8 loosening the nut 10, moves the connecting杆側serration member 7 side in the vertical direction, after adjusting the height position, the clamping basis weight to a solid <br/> constant nut 10. Further, the rubber bush joint 4, the nut 16 Ru clamping basis weight <br/> the state elastic by <br/> the rubber bushing can be sufficiently obtained.

[0012]

[Effect of the Invention] The mounting device of the present invention can be selected horizontally.
Mounting portion having a serration mechanism provided with Shon grooves, are respectively attached directly to the bogie frame and gearing, and since both of the mounting portion are linked coupled with articulated rod via a rubber bush joint, height Can be adjusted over a wide range
The height can be easily adjusted, and the installation of the mounting device is simplified.
it can. Further, the bracket on the bogie frame side is omitted, which helps to reduce the bogie weight.
