Definitions

  • the invention relates to an electric drive, in particular a windshield wiper drive for vehicles, according to the preamble of the independent claim.
  • the motor is arranged in a cup-shaped, metallic housing, which is assembled with a transmission housing.
  • an insulating base plate as a support for the motor brushes and other electrical components.
  • Three reactors for radio interference suppression of the motor are arranged on both sides of the base plate partly in the motor housing, partly in the gear housing without noise shield.
  • the electric drive according to the invention with the features of the independent claim has the advantage that the drive can be made very compact overall by the existing preferably in the metallic motor housing free space for the partial housing of the suppression device is used.
  • this, however, the interference suppression effect is improved because it is avoided that leads from the engine compartment to the suppression means protrude into the shielded area of the gear housing and emit interference there.
  • Gear housing facing end face of the motor housing largely covers, leaving only a recess for the passage of the motor shaft and at least one further recess for the passage of a electrical interference suppression element such as a choke coil, these recesses can each be minimized specifically to the required fürerieshus.
  • the inductor aligned axially parallel to the motor shaft and is preferably arranged with the greater part of their length in the motor housing, while their remote from the motor housing, filtered end protrudes into the transmission housing and protected by the metallic end shield against emanating from the commutator of the engine noise is.
  • the gear housing made of metal, preferably made of aluminum or an aluminum alloy.
  • the suppression device of the electric drive consists of two inductors and three capacitors, the two inductors are arranged axially parallel to each other and the motor axis and combined with a, between their averted from the engine ports capacitor to a suppression module, which in the previously discussed manner in the transition region is arranged between the motor housing and the transmission housing.
  • Show it 1 shows a longitudinal section through an inventive
  • FIG. 2 is a schematic diagram of the invention
  • FIG. 1 shows an electric windshield wiper drive for a motor vehicle is shown with an electric motor 10 and a transmission 12 for reducing the engine speed to a lower drive speed.
  • the engine 10 is disposed in a motor housing 14 which
  • the transmission 12 essentially consists of a drive worm 30 rotating with the drive shaft 20 of the motor 10, which meshes with a worm wheel 32, which in turn is fixedly connected to an output shaft 34.
  • the gear housing is closed parallel to the cutting plane with a lid, not shown.
  • a bearing plate 36 for an engine mount 21 which rests on a flange 38 of the motor housing and the latter with the exception of a recess 40 for the passage of the drive shaft 20 and another recess 42 covers through which two throttle coils 46 and 48 held in a plastic carrier 44 pass.
  • the inductors 46 and 48 are arranged congruently one behind the other, so that in Figure 1, only one lying in the cutting plane coil is visible.
  • first capacitor 50 which bridges the two inductors 46 and 48, as shown in Figure 2 circuit.

  • Transition region from the motor housing 14 to the gear housing 16 for supporting the engine mount to the end plate 36 is attached.
  • This likewise metallic, preferably made of steel bearing holder 56 covers at least the commutator 22 and thereby increases the shielding effect for the coil ends 47 and 49th
  • FIG. 2 shows the block diagram of a permanent magnet excited electric motor 10, which is fed from a DC voltage network. Two different speeds for the motor 10 are obtained by optional connection of terminals 62 and 64 with the positive pole of the DC voltage network, whose Massepol is designated 60.

Abstract

L'invention concerne un entraînement électrique, notamment un entraînement d'essuie-glace pour des véhicules, comprenant : un moteur électrique (10) dans un boîtier de moteur (14) en forme de pot, de préférence métallique ; un boîtier de transmission (16) rapporté sur le boîtier de moteur (14) ; et un dispositif de déparasitage du moteur (10). Selon l'invention, au moins une bobine d'inductance (46, 48) pour le déparasitage du moteur (10) est disposée dans la région de transition du boîtier de moteur (14) au boîtier de transmission (16). Dans cette région de transition, des moyens (36, 56) sont prévus pour protéger l'extrémité filtrée (47, 49) de la bobine, pénétrant dans le boîtier de transmission (16), vis-à-vis du rayonnement parasite produit par le moteur (10).
