Definitions

  • the invention relates to a drive unit for electric rail vehicles. See for example DE 195 30 155 A1 .
  • WO 96/25314 A1 , DE 102 25 708 B4 describes a gear housing for receiving a Getriebegrßrades, with a housing cover which is equipped with a flange.
  • the gearbox is made in one piece in the area of a bearing.
  • the lid is designed as a partial hood.
  • a drive unit with the features defined in the preamble of claim 1 is made EP 0 792 784 A1 known.
  • the invention has for its object to design a drive unit of the type mentioned in such a way that the mass of the components involved can be kept as low as possible, and that the driving dynamics compared to known drive units is improved.
  • the inventor has recognized a significant disadvantage of conventional drive units: If the housing consists of two components, they must each be clamped separately on processing machines for machining, for example for drilling or milling. This leads to the fact that manufacturing tolerances add up when pairing. Instead, the one-piece housing allows its manufacture in a single set-up on the machine tool. The otherwise additive manufacturing tolerances are thus significantly reduced.
  • FIG. 1 can be seen a drive shaft 1, which carries not shown wheels at both ends.
  • the drive shaft is mounted on a support tube 2, by means of Tatzlager not recognizable here.
  • a housing 3 is divided into two - see the housing main body 3.1 and the cover 3.2.
  • Support tube 2 and housing 3 are connected by a flange 2.1 and by means of screws firmly together.
  • the housing encloses a spur gear, not shown here, and a drive pinion 4.
  • brackets 5, 6 are provided at the support tube 2. These carry an engine, not shown here.
  • the output shaft of the engine operates on the drive pinion. 4
  • FIG. 2 In turn, the housing can be seen, more precisely parts of the lower housing part also the drive pinion 4 enclosed thereby.
  • the support tube 2 has a single console 5.
  • the bracket 5 is attached to the support tube 2.
  • Support tube 2 can be produced for example as a casting, in a single operation together with the housing parts 3.1 and 3.2.
  • the engine is again not shown here. However, one recognizes a motor bell 7. This is in the present case frustoconical. It includes a ring 7.1 and spokes 7.2. The spokes 7.2 are - viewed in the direction of the axis of rotation of the drive pinion 4 - arranged radially. Their radially outer ends engage the ring 7, and their radially inner ends on the main part 3.1 of the housing.
  • the motor is mounted on console 5 and on ring 7.1 of the motor bell.
  • the fan air of the engine passes through the spaces between the spokes 7.2 to the outside.
  • a significant advantage of the embodiment according to the invention according to the FIGS. 3 and 4 consists in the one-piece of the housing 3, more precisely, the main part of the housing 3.1. This can be achieved when editing the housing significant savings. Although you could also screw the housing parts 3.1 and 3.2 in two-part design before finishing, to avoid adding manufacturing tolerances. Then, however, the two parts would have to be marked so that they can later be assigned to each other. In the one-part embodiment according to the invention, this is eliminated.
  • the main part 3.1 of the housing 3 and support tube are in one piece, since the support tube 2 is molded onto the housing main body 3.1.
  • the sole console 5 and the exact positioning of the motor bell 7 ensure an exact positioning of the motor and its fixation with significant reduction of the negative effects of static overdetermination.
  • the drive pinion 4 is connected to the engine via a diaphragm coupling 8 in drive connection.
  • a diaphragm coupling 8 in drive connection. Due to the high running accuracy and the high radial rigidity of the diaphragm coupling 8, the rotor of the motor is accurately and reliably felt, even without own storage.
  • diaphragm coupling 8 can be divided and the parts connected to one another with a screw connection
