Definitions
- the invention relates to the field of rail vehicles. It particularly relates to an axle drive for this purpose.
- Such a final drive comprises a wheelset shaft. On each end of the wheelset shaft sits an impeller which is rotatably connected to the shaft.
- the wheelset shaft is driven by a motor.
- the axes of rotation of the wheelset shaft and motor are parallel to each other.
- a transmission is connected between the engine and the wheelset shaft.
- the gearbox is located between one of the two wheels and the engine. It includes a large sprocket keyed onto the sprocket set shaft and a sprocket keyed onto the motor shaft. Pinion and gear mesh with each other. Pinion and gear are enclosed by a housing.
- the invention has for its object to make a final drive of the type described above such that a decoupling of motor and wheelset shaft is easy and fast to carry out.
- the gear housing can be opened in the region of the pinion on the side of the impeller located there.
- the width of the gap between the pinion and the impeller is generally at least equal to the length of the pinion.
- the pinion is easily removable from the motor shaft and can be moved into the intermediate space.
- the rotationally fixed connection between the pinion and wheelset shaft of the engine is released, and at the same time repealed the drive connection between the engine and Laufradsatzwelle.
- the pinion can now be provisionally held in the gap. The blockage of the entire vehicle due to the faulty drive is canceled, and the vehicle can drive on its own with the help of further drives.
- Impeller out In this position, it can be removed by further displacement parallel to the axis of the wheelset shaft.
- Figure 1 shows a conventional axle drive with a view towards the axis of the wheelset shaft.
- Figure 2 shows the article of Figure 1 in a plan view.
- Figure 3 shows a final drive according to the invention, again with a view towards the axis of the wheelset shaft.
- FIG. 4 shows the article of Figure 3 in plan view
- FIG. 5 again shows an axle drive according to the invention analogous to that according to FIGS. 3 and 4, but with further details.
- the conventional final drive shown in Figure 1 has a Laufradsatzwelle 1 on.
- the wheelset shaft carries two wheels 2, 3, with which it is rotatably connected. It is a drive motor 4 is provided. Its axis of rotation 4.1 runs parallel to the axis of rotation 1.1 of the wheelset shaft.
- a transmission 5 is connected between the drive motor 4 and the wheelset shaft 1.
- the transmission is located in the space between one of the two wheels, namely the impeller 2 and the motor 4. It has a gear 5.1.
- the gear is keyed onto the wheelset shaft 1. It also has a pinion 5.2.
- the pinion 5.2 is keyed onto the motor shaft. Gear 5.1 and pinion 5.2 are enclosed by a gear housing 5.3.
- the drive motor 4 is supported on a support tube 6. This is mounted on the wheelset shaft 1.
- the introduced via the drive motor 4 torque is supported by torque arms, not shown here.
- the torque arms engage on the one hand on the drive motor 4, and on the other hand on the bogie of the final drive.
- FIGS. 3 and 4 The solution according to the invention is shown in FIGS. 3 and 4. Identical components are provided with the same reference numerals as in FIGS. 1 and 2.
- the solution according to the invention has the following features over the conventional design:
- the gear housing 5 is on its side facing the impeller 2 apparently. It may for this purpose, for example, have a cover 5.4.
- the pinion 5.2 can be removed after removing the cover 5.4 from the shaft of the drive motor. It is thereby transferred into the intermediate space between the gear 5 and the adjacent impeller 2, thus in a direction parallel to the axis of rotation of the Laufradsatzwelle 1.
- the space between the end face of the pinion 5.2 and the side surface facing the impeller 2 must of course be sized accordingly , Its width must be at least equal to the length of the pinion 5.2, generally even slightly larger.
- the remaining components of the final drive can remain mounted as they are. It thus no longer requires a release of the drive motor 4 from the support tube 6, or the rest of the transmission from the drive motor 4 and the bogie not shown here.
- Both wheels 2, 3 are associated with brake devices 7, 8, which is indicated here only for the sake of completeness.
- a device can be seen, with which the pinion 5.2 is deducted from the shaft of the drive motor 4.
- a spacer sleeve 9 is used. This is dimensioned such that on the one hand, a complete release of the pinion 5.2 can be done by its displacement in the axial direction, and on the other hand, the displacement is limited by a support on the respective side of the impeller 2. This limitation is for safety.
- a pressure for releasing the interference fit by hydraulic oil is applied by means of an angle fitting.
- the transmission housing 5 can hermetically seal the enclosed space.
- the housing 5 may also be designed so that it serves only the protection of gear 5.1 and pinion 5.2 and the inclusion of the lubricant for these two wheels, since the forces superimpositions are received in the support tube 6 and in the drive motor 4.
- bleeder and non-contact seals can be provided, via which a pressure equalization between the interior of the transmission housing and the external environment takes place.
- gearbox housing must also absorb forces. Are in the gearbox but no gearbox bearings arranged, as in the case shown, the housing is only the protection and the oil supply. LIST OF REFERENCE NUMBERS
