EP2164740B1 - Bogie for a rail vehicle which has a drive - Google Patents

Description

The invention relates to a bogie for a provided with a drive rail vehicle, for example for a locomotive.

Such a bogie has a bogie frame. The frame carries one or more wheelsets. Each wheelset includes wheels, a final drive with a wheelset and a gearbox housing.

Another component of the bogie is a pull-push rod. This attacks on the one hand on the bogie frame, and on the other hand on the locomotive frame. It transmits forces between these two.

Wheelsets for bogies are known, for example from WO 2005/017394 A1 ,

A big problem of such bogies is the volume of construction. This is particularly about the available space in the vertical direction. The train-pressure rod is usually placed above the Radsatzgetriebes. This encounters difficulties, since the space above the wheelset space is limited in its height. One could also think of placing the pull-push bar between the lower edge of the wheelset and the track bed. The necessary ground clearance is not available.

The known embodiments are therefore of very compact construction. This is unfavorable in terms of assembly and the optimal design of the elements involved.

The invention has for its object to make a bogie according to the preamble of claim 1 such that the wheelset - or the wheelset - and the push rod without the above complications can be arranged without affecting their functions, with ease of installation.

This object is solved by the features of claim 1. Accordingly, the single Radsatzgehäuse is provided with a through opening for passing the train-push rod. The insertion opening is bounded by walls of the housing. These are in one piece with the rest of the housing wall, so that the interior of the housing is still hermetically sealed from the outside environment. There is thus no interaction between the wheelset housing and the train-pressure rod.

The insertion opening is enclosed by the transmission housing, so that the train-push rod is passed through the insertion opening and thus through the transmission. Optionally, the housing can be widened parallel to the shaft of the wheel set to provide sufficient space for the gears and for the bearing lubricating oil.

With bevel gear teeth, the bevel gear axis can be offset to provide additional clearance for the pull-push rod.

The low-lying train-push rod transmits longitudinal forces between bogie and locomotive frame. The Achsentlastung when starting and the restoring forces at Bogenfahrt are thereby kept low. The pull-push rod is expediently arranged centrally in the y-direction, ie in the middle between two wheels of one axle.

If no sufficient oil supply and oil return or the necessary tightness under all operating conditions is ensured, then an output bearing can be grease lubricated.

The invention can be used particularly advantageously in bogies with two or more sets of wheels, for example with three wheelsets.

This in FIG. 1 shown bogie is intended for a locomotive. It is constructed as follows: It comprises three sets of wheels 2, 3, 4. Each wheel set comprises two wheels 2.1, 2.2; 3.1, 3.2 and 4.1, 4.2, also wheelset shafts 2.3, 3.3 and 4.3 (see the FIGS. 2 and 3 ), a Radsatzgetriebe 2.4, 3.4, 4.4 and a Radsatzgehäuse (see FIG. 8 ).

It also recognizes four springs 5. These are connected between the bogie and the locomotive frame, not shown, also springs 6, which are connected between the frame 1 and the respective shaft.

FIG. 2 shows an important component, namely a train-pressure rod 7. pull-push rod 7 engages via a pin 8 on the one hand on the frame 1, on the other hand, via a Anlenkturm 9 on the locomotive frame, not shown. The train-push rod 7 serves to transmit forces between the bogie frame 1 and the locomotive frame.

The key features of the invention will become apparent from the FIGS. 7 and 11 ,

The FIGS. 5 to 6 let each recognize a non-inventive housing 10 of a wheelset.

In the case of the non-inventive example according to FIG. 5 the housing has an open-edged recess 10.1. This covers an area on both sides of the longitudinal center plane of the associated bogie.

In the example not according to the invention FIG. 6 In turn, an open-edged recess 10.2 is provided in the housing. This is located in a corner region of the housing 10.

In the embodiment according to FIG. 7 the recess is formed according to the invention as a through opening. She is more accurate FIG. 11 recognizable.

Through the recesses, it is possible to put said pull-push rod 7 in a position which is located above the lower edge of the housing 10. There remains thus the ground clearance, which is predetermined by the housing 10.

The non-inventive example according to FIG. 8 again shows an open-edged recess 10.2 with a semicircular contour. The recess thus forms a half-cylinder.

The non-inventive open-edged recess according to FIG. 9 is formed by the fact that a corner of the housing 10 is effectively cut off.

FIG. 10 shows a not according to the invention Radsatzgetriebe 2.4 with a wheelset 2.3. The housing 10 is provided with a recess 10.1. It also has a stiffening rib 10.5. A grease lubrication bearing 11 is located in a left-hand area. An axle offset 12 is provided in the output bevel gear stage, which creates additional clearance for the tension-compression rod 7.

On the housing 10 sits a U-shaped bracket 14 for a torque arm 15 (see also FIG. 11 ). The torque arm 15 is located in the middle between the two wheels 2.1 and 2.2. As you can see, it is located clearly above the axle 2.3.

FIG. 11 shows a complete set of wheels with a final drive 2.4 according to the invention, further with a shaft 2.3 and with wheels 2.1, 2.2.

The housing 10 of the transmission is provided with an insertion opening 10.3. A train-pressure rod, not shown here, can be passed through the insertion opening 10.3. The rod lies in a horizontal plane. Deviations from the horizontal are possible here. The train-pressure rod runs in the longitudinal direction of the bogie. It can also be inclined against the longitudinal direction.

The housing 10 of the wheelset 2.4 is divided in a horizontal parting plane 13. The lower part, which contains the insertion opening 10.3, serves primarily as an oil reservoir.
