Abstract

PURPOSE:To facilitate the joining work between a bogie frame and a car body by installing an adapter connected with a car body longitudinal force receiving part, at one edge of a traction link whose the other edge is connected with the bogie frame, and by installing an adjusting rod between a bracket in the lower part of the adapter and the bogie frame and permitting the traction link to be held horizontally. CONSTITUTION:One edge of a traction link 4 is connected with the cross beam 7 of a bogie frame through a rubber bush 19, and an adapter 6 is installed at the other edge of the traction link 4. The car body 1 and the bogie frame are connected by connecting a longitudinal force receiving part 2 of the car body 1 through a pin 10 and bolt 18 of the adapter 6. A bracket 11 is installed under the adapter 6, and an adjusting rod 12 having a nut 15 is installed between the bracket 11 and the other cross beam of the bogie frame. The adapter 6 can be held horizontally by the turn of the nut 15, and when the car body and the bogie frame are connected, the adapter 6 can be held horizontally, and joint work can be carried out in simple manner.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a car body support device for a railway vehicle bogie, and particularly to a single body support system for a railway vehicle bogie suitable for a bolsterless bogie.
This is related to the 1st shift.

[Conventional technology]

In the conventional vehicle body support device, as in Patent No. 1355177, an adapter to which a 1Iavt force receiver and a traction link are attached are bolted together, and the vehicle body is cut 1) ML.
The bolts were used to connect the parts. Rubber bushings are provided at both ends of the towing link, and when the bogie is alone before being connected to the car body, one end of the towing link is fixed to the bogie frame.
The other end is provided with an adapter that is coupled to the longitudinal force receiver. In such a configuration, the towing link is a cantilever beam with a so-called adapter at the tip (1), and the rubber bushing fixed to the bogie frame is subject to torsion, so the towing link is horizontal. Moreover, when mounting the vehicle on the vehicle body and bolting the longitudinal force receiver to the adapter, the towing link had to be held in a horizontal position.

[Problem to be solved by the invention]

The above-mentioned prior art does not give sufficient consideration to the work of joining the car body and the bogie, so-called car body mounting work, and there is a problem in that the car body mounting process requires a large amount of opening and opening.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle body support device that allows easy connection of a vehicle body and a bogie.

[Means to solve the problem]

The above purpose is one end! 'ff A towing link connected to the rear support, the other end of which is connected to the bogie frame, and connected with an elastic body interposed between each connecting portion, and a towing link provided on the bogie frame so as to be engageable with the towing link. This is achieved by having a structure that includes a holding means for holding the front and rear force receivers in a connected state.

[For production]

The towing link is held in a state where it is connected to the front and rear force receivers by the holding means, that is, in a substantially horizontal state, so that when a vehicle body is mounted on a bogie, the tow link is connected to the front and rear force receivers of the vehicle body! No. 111, the adapter provided at one end of the towing link is opposed and held in a state where it can be easily connected. Therefore, the work of connecting the vehicle body and the truck can be easily performed.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 4. In the same figure, there is a longitudinal force receiver 2 at the center of the vehicle end of the vehicle body L.
is attached by bolts 3 or welding. An adapter 6 is provided on the lower surface of the longitudinal force receiver 2 to which one end of the traction link 4 having rubber bushings 19 at both ends is connected by a bolt 5.
The other end of the traction link 4 is attached to a bracket 8 provided on a horizontal beam 7, which is a part of the bogie frame, via a bolt 9. When the truck is alone, the traction link 4 is not horizontal with respect to the rail surface, as shown by the solid line in FIG. 4, mainly due to the weight of the adapter 6, and the adapter 6 has a certain inclination. For this reason, a bolt 18 is provided at the center of the adapter 6 to serve as a guide during the connection work with the longitudinal force receiver 2 and to prevent damage to the bolt 18 that connects the longitudinal force receiver 2 and the adapter 6. pin 1
The diameter of 0 and the fitting hole provided in the longitudinal force receiver 2 have a fitting tolerance of a clearance fit, making the joining work difficult.

Furthermore, during the work of mounting the vehicle body, it is necessary to connect the pin 1O and the longitudinal force receiver 2 while slightly moving the truck in the longitudinal direction. jll! IL, it will be necessary to make slight adjustments when mounting on the vehicle.

In order to perform the above operation, a slit portion is provided at the tip of the bracket 11 provided on the adapter 6 as shown in FIG. ! 1. Attach one end of the straightening bar through the pin 14.

The other end of the adjustment rod 12 is threaded, and the adjustment rod is inserted into the slit provided in the bracket 11, and the nut 15 is used to adjust the horizontal level of the towing link 4 and adapter 6. rII4! ! can.

When mounting the vehicle body is completed, nut b is loosened to release straightening bar 21 from adapter 6, and mgls 12 is fixed to bracket 16 provided on cross beam 7 with bolt 17. Due to the second reason, the towing link 4 is not restrained by the horizontal beam 7, so that the vehicle can travel.

According to such a configuration, the traction link 4 can be positioned in any desired state when the bogie is alone, and the adapter 6 can be maintained in an appropriate state with respect to the longitudinal force receiver 2 when a vehicle body is mounted on the bogie. Therefore, during the work of joining the vehicle body and the bogie, the adapter 6 is held at an appropriate position relative to the longitudinal force receiver 2, and the position of the adapter 6 is also adjustable, making the work extremely easy. Easy to do.

Further, the adapter 6 and the llff1 & force receiver 2 can be accurately positioned, and the jig is used during work.

No special tools are required.

On the other hand, the notation bracket 11 and! fil! ! ! In addition to the positioning function described above, the holding means for the traction link 4 made of a bar also has a function as a means for fixing the traction link 4 when the cart is transported by itself.

In the embodiment H, the holding means, that is, the bracket 11 and the adjustment rod hill were installed between the adapter 6 and the crossbeam 7, but the present invention is not limited to this.
A similar effect can be achieved even if it is installed between the traction link 4 and the horizontal beam 7. Further, although a bolt structure is used as the adjustment mechanism, a turnbuckle, chain, etc. may also be used.

〔Effect of the invention〕

As explained above, according to the present invention, the work of connecting the vehicle body and the bogie can be easily performed.
