Definitions

  • the invention relates to a double-axle drive and an undercarriage of a rail undercarriage.
  • center drives or one external longitudinal drive each i.e. so-called double axle drives
  • an axle drive is mounted on a traction motor at the respective ends of its rotor shaft to drive a wheel or wheel set, resulting in a multi-part housing construction.
  • the housing of the traction motor of this longitudinal drive has only included an end shield, with the gears each having their own housing with a gear cover and thus the entire construction of the double-axle drive consists of several parts, in particular housing parts, as is the case, for example, in EP 0 718 170 A1 can be seen.
  • the object of the invention is to simplify such a double-axle drive with regard to its structure.
  • the solution to the task is achieved by means of a double-axle drive with two driving axles and with a single traction motor arranged between the two driving axles, the axis of rotation of which runs transversely, in particular perpendicularly, to the driving axles, with a wheel set shaft being able to be driven by means of a drive shaft of the traction motor via a gearbox in each case, with the entire double-axle drive is arranged in a housing unit which has two housing sections, the housing sections being the drive axles protrude in the direction of the axis of rotation of the traction motor and encompass this up to 180 degrees, and the housing sections are each closed off by a gear cover, which is fastened to the respective housing section by means of a flange connection.
  • the two housing sections have flange surfaces facing one another, to which the housing sections can be fixed, the flange surface running in particular perpendicularly or parallel to the drive shaft.
  • only one housing unit is now provided between the two driving axles, which now contains components of the traction motor, the bearing, the clutch and two gears, so that the manufacturing and assembly costs and also the weight are reduced compared to conventional double axle drives.
  • the gear is designed as a hypoid bevel gear or as a normal bevel gear.
  • These compact transmissions are particularly suitable for such double-axle drives, since the flow of power can be redirected in an almost ideal way in the smallest of spaces.
  • flange surfaces are designed at the joints, at which these two housing sections can be connected.
  • these flange surfaces run perpendicular to the drive shaft of the rotor of the traction motor or parallel to the drive axles. This simplifies the manufacture of such flange surfaces.
  • the flange faces are provided outside, in particular axially outside, of the laminated core of the stator. This also simplifies the shrink fit of the laminated stator core within the housing section provided for this purpose. This improves the torques acting on the laminated stator core when the double-axle drive is in operation recorded. The detachability of the respective housing sections is also retained.
  • FIG 1 shows a longitudinal section of a double-axle drive, which is suitable both as a central drive and as an external longitudinal drive, in particular for low-floor vehicles.
  • a traction motor 3 is arranged between two drive axles 14 and has a laminated stator core 4 and a laminated rotor core 5 surrounding a rotor shaft 7 .
  • the rotor shaft 7 which can be rotated about an axis of rotation 6 , is mounted via bearings 9 .
  • the laminated core 4 of the stator is accommodated in a housing unit 15 in a rotationally fixed manner.
  • the housing unit 15 is divided into two housing sections 16 and 17 which can be connected to one another at a flange surface 10 .
  • the flange surface 10 of the flange is in the area of the stator core 4.
  • Parts of the traction motor 3, clutch 8, bearing unit 23 for gear 18 and traction motor 3 are in each case in the housing sections 16, 17.
  • a brake can also be arranged in at least one of the housing sections 16, 17, in particular between the clutch 8 and the traction motor 3.
  • the flange surfaces 10 of the flange are located axially outside of the stator core 4.
  • the stator core 4 thus has a continuous seat in a housing section. This simplifies the disassembly of the housing sections 16, 17. In this way, for example, electrical connections of the winding system of the traction motor 3 can be arranged in an accessible manner on one side of the laminated stator core 4 in a particularly favorable manner.
  • the housing section 16 contains, among other things, the traction motor 3, the clutch 8, a bearing unit 23 for the gear 18 and the traction motor 3, and optionally a brake.
  • the clutch 8 and a bearing unit 23 for the transmission 18 are arranged in the other housing section 17 .
  • optional air guiding devices for cooling air flows, as well as coolant inlets 11 or coolant outlets 12 on the shell of the housing sections 16, 17 can be provided.
  • housing unit 15 in particular in the housing sections 16 and 17, air inlets 11 and/or air outlets 12 are provided in the wall of the housing sections 16, 17. Also within the housing unit 15 is a respective clutch 8, both to a driving axle 14 and to the other driving axle 14, respectively. The entire housing unit 15 is placed via springs 13 in a bogie (not shown) of a rail vehicle.
  • the respective housing sections 16, 17 also each receive the bearing assemblies 23 in corresponding bearing seats of the housing sections 16, 17, which are preferably located between the transmission 18 and the clutch 8.
  • the respective housing sections 16, 17 protrude axially—viewed from the traction motor 3—over the driving axles 14.
  • the housing sections 16, 17 thereby encompass their respective driving axle 14 both FIG 1 as well as after FIG 2 up to 180 degrees. In other words: an imaginary extension of the flange surfaces of the flanges 21 goes through the respective driving axle 14.
  • the housing sections 16, 17 are each closed off by a gear cover 20, which is fastened to the respective housing section 16, 17 by means of flange connections 21.
  • the gear cover 20 each have a maintenance opening 22 .
  • each wheel or wheel set with two wheels is driven by a gear 18 each wheel or wheel set with two wheels.
  • the drive axles of these wheels or these wheel sets run essentially perpendicular to the axis of rotation 6 of the traction motor 3.
