Definitions

  • the invention relates to a single-axle drive of a rail vehicle, which is arranged on a wheelset shaft of a wheelset of the rail vehicle.
  • EP 0 758 602 A2 discloses a pawl bearing drive in which a rotor shaft of the motor carries a shaft extension provided with a pinion on the output side shaft end and an outer bearing of the rotor shaft with an outer drive or A side rotor shaft bearing on a Achsansatzstummel and a brush or B-side rotor shaft bearing in a B -side engine end shield is provided.
  • the invention has for its object to provide an improved in particular with regard to the assembly and disassembly Einzelachsantrieb a rail vehicle.
  • An inventive single-axle drive of a rail vehicle is arranged on a wheel set shaft of a wheel set of the rail vehicle and comprises an engine, a motor housing surrounding the motor housing, a transmission and a transmission housing surrounding the transmission.
  • the transmission housing consists of two gear housing parts which abut each other in a connecting plane in which a longitudinal axis of the wheelset shaft, and are detachably connected to each other.
  • the two-part design of the gear housing and the detachable connection of the gear housing parts allow the installation of the single-axle drive on the axle and the dismantling of the axle. Characterized in that the transmission housing parts abut each other in a compound axis containing the longitudinal axis of the axle and are connected to each other, the gear housing parts can be easily placed on the wheelset with components arranged thereon or the wheelset are inserted with these components in a gear housing part.
  • connection plane forms a non-vanishing angle with a vehicle vertical axis of the rail vehicle.
  • the angle can be advantageously chosen such that it facilitates placement of the gear housing parts on the wheelset or inserting the axle in a gear housing part and thus the assembly and disassembly of the single-axle drive. Furthermore, the angle can advantageously be chosen such that a ground clearance of the arrangement of the single-axle drive is optimized on the axle and, for example, in the case of a flange connection of the gear housing parts is not affected by a flange.
  • a further embodiment of the invention provides that the two gear housing parts are connected to each other in the connecting plane by means of a flange connection.
  • a flange connection advantageously enables a reliable releasable connection of the gear housing parts.
  • a further embodiment of the invention provides that a gear housing part has a housing wall, which is designed as a driven-side engine bearing plate of the engine.
  • the engine end shield and a gear housing part are advantageously designed as a component, whereby the number of components of the single-axle drive is reduced and the assembly and disassembly of the single-axle drive is further facilitated.
  • a further embodiment of the invention provides that the gear housing is supported with a first Tatzlager on the wheelset.
  • the first pawl bearing is preferably designed as an annular bearing running around the wheelset shaft, for example as a cylindrical roller bearing.
  • a further embodiment of the invention provides that one of the output side opposite housing end portion of the motor housing is supported with a second Tatzlager on the wheelset.
  • the second Tatzlager is preferably designed as a ring around the wheelset around extending rolling bearing, for example, as a Kuggellager.
  • a further embodiment of the invention provides a bearing half-shell surrounding the second Tatzlager semi-circumferentially, which rests in the connecting plane on the housing end of the motor housing and is detachably connected to the housing end.
  • the housing end region of the motor housing and the bearing half shell are releasably connected to one another in the same connection plane as the two gear housing parts. This further simplifies the assembly of the Einzelachsantriebs on the axle with the components arranged on it (especially the Tatzlagern) and disassembly of the Einzelachsantriebs of the wheelset with these components without components of the Einzelachsantriebs remain on the wheelset, so that the wheelset and the their arranged components are easily accessible for maintenance purposes.
  • a further embodiment of the invention provides that the motor has a motor shaft arranged parallel to the wheelset shaft.
  • a further embodiment of the invention provides that the transmission comprises at least one pinion carried by the motor shaft and a large wheel cooperating with the pinion and carried by the wheel set shaft.
  • FIGS. 1 and 2 show a single-axle drive 1 of a rail vehicle, which is designed as a so-called Tatzlagerantrieb and arranged on a wheelset 3 of a wheel with drive wheels 4 of the rail vehicle. It shows FIG. 1 a sectional view of the single-axle drive. 1 FIG. 2 shows a side view of the Einzelachsantriebs 1 with a sectional view of the axle 3 from a right in Figure 1 located output side of the Einzelachsantriebs first
  • the single-axle drive 1 comprises a motor 5, a motor housing 7, a transmission 10 and a transmission housing 11.
  • the motor 5 has a motor shaft 13, which is arranged parallel to the axle 3.
  • a driven-side end of the motor shaft 13 carries a pinion 15, which cooperates with a shrunk onto the wheelset 3 large gear 17.
  • the pinion 15 and the large gear 17 form the gear 10 designed as a transmission gear 10 of the single-axle drive. 1
  • the transmission housing 11 surrounds the transmission 10.
  • the transmission housing 11 is formed in two parts and consists of a first gear housing part 19 and a second gear housing part 21.
  • the two gear housing parts 19, 21 are connected via a flange 23 in a connecting plane 24, in which a longitudinal axis 25 of the wheelset 3 extends, releasably connected to each other by means of first connecting elements 26.
  • the connection plane 24 divides the space into a first half space H1, which contains the first gear housing part 19, and a second half space H2, which contains the second gear housing part 21.
  • the first gear housing part 19 has a housing wall 9, which is designed as a drive-side engine end shield of the engine 5 and receives a driven-side motor shaft bearing 12.
  • the first gear housing part 19 surrounds the output-side end of the motor shaft 13 and the pinion 15 and half-circumference the large gear 17 in the first half space H1.
  • the second gear housing part 21 circumferentially surrounds the large gear 17 in the second half space H2.
  • the single-axle drive 1 is supported with Tatzlagern 29, 31 on the wheelset shaft 3.
  • the pawl bearings 29, 31 are each arranged on the wheel set shaft 3 and designed as roller bearings, which extend in an annular manner around the wheelset shaft 3.
  • the gear housing 11 is supported with a first Tatzlager 29 on the wheelset shaft 3.
