Definitions

• the invention relates to an axle drive for rail vehicles with an electric motor arranged on a drive axle, to which a gear and a clutch are assigned to the drive axle.
• an electric motor-gear unit for the drive of rail vehicles which, as a transverse drive, has a motor arranged parallel to the drive axis of the rail vehicle and an axle drive connected to the motor, as well as an output clutch connected to the axle drive comprises, wherein the motor shaft carrying the rotor of the motor is designed as a hollow shaft.
• the hollow motor shaft which carries a fan, is overhung on an outwardly extended drive shaft of the transmission and connected to it in a positive and / or non-positive manner.
• the motor housing is connected to the gear housing
• the gear housing which contains a two-stage reduction, which drives onto a large wheel attached to the wheel axle, is rotatably supported on the wheel axle via bearings.
• the transmission housing is held on the bogie frame of the vehicle to record the reaction torque.
• This known transverse drive with the electric motor arranged parallel to the wheel axis of the rail vehicle requires a relatively large installation space and has a disadvantageous arrangement on the chassis for assembly and disassembly.
• the object of the present invention is to provide an axle drive of the type mentioned at the outset, which is distinguished by a compact design, requires only a small installation space on the undercarriage and enables high flexibility in fastening to the undercarriage.
• axle drive according to the preamble of claim 1 in that the drive consisting of electric motor, transmission and clutch is supported on the end by spring and damping means and with the interposition of axle bearings on the drive axle.
• the drive unit consisting of an electric motor, gearbox and clutch is arranged directly on the drive axle of the rail vehicle, which, in addition to a simple construction, results in a compact design which takes up little installation space and which arranges the drive directly on the wheel axle between the Driving wheels of the rail vehicle enables.
• an axle drive there is sufficient scope for attachments of the
• Drive and chassis e.g. for a brake or a possibly required fan.
• the advantage here is the ease of assembly and the replacement of the entire drive unit as a structural unit, comprising the wheel axle with the drive.
• the axle drive comprises an electric motor 2 arranged on the drive axle 1 of a rail vehicle between the drive wheels (not shown), a gear 3 and a clutch 4 for power transmission of the electric motor to the drive axle 1.
• the standing motor housing 8 is fastened by a torque support 12 against the chassis or the vehicle frame of a rail vehicle, not shown.
• a housing 20 of a planetary gearbox 3 is arranged on the motor housing 8.
• the motor bearing plate 10 facing away from the transmission is mounted on the motor shaft 9 by a motor bearing 17, the
• Rotor 13 carrying motor shaft 9 is designed as a hollow shaft through which the drive axle 1 is guided, which carries the drive wheels, not shown, of a rail vehicle. Furthermore, a receptacle 11 is flanged to the motor end shield 10, via which the motor housing and the stator 18 of the electric motor are supported against an axle bearing 6 of the drive axle 1 in such a way that between the receptacle 11 of the motor end shield 10 and the axle bearing outer ring 7 Axial bearing 6, a spring and damping means 5, in particular a rubber-metal element, is used. With 25 an end cover is designated.
• the motor housing with the bearing plate 21 and a second motor bearing 16 are mounted on the hollow shaft 9, a shaft seal 22 being associated with this bearing point.
• the hollow shaft 9 of the motor carries a special nenrad 14. According to the exemplary embodiment shown, this is
• Planetary gear 3 designed as epicyclic gear and non-positively connected with its planet carrier 15 to the clutch 4. Furthermore, the gear 3 with its planet carrier 15 is mounted on the motor shaft 9 via a gear bearing 19.
• the planetary gear is arranged between the gear bearing 19 arranged on the clutch side and the motor bearing 16 on the gear side.
• the gearbox mounting can also be provided between the planet carrier and the motor shaft on the gearbox side facing the electric motor.
• the coupling 4 is designed as a handlebar coupling or as an elastic membrane coupling.
• the drive is supported against the drive axle 1 via the clutch 4, via clutch carriers 23, 24 and via elastic elements (not shown).
• the clutch 4 which is resilient and mounted against the drive axle 1, can also be accommodated in the transmission housing.
• a spring and damping means arranged outside the transmission housing can be provided for support on the drive axis, the spring and damping then sits on an outer bearing ring of an axle bearing.
