Definitions

  • the invention relates to a drive device for a fan module and a method for producing such a drive device.
  • a fan module as, for example, is used on board a motor vehicle for conveying fresh air into a passenger compartment, typically comprises an electric motor with a fan wheel.
  • the electric motor is accommodated in the housing in a manner which damps vibrations, and the housing is prepared for installation in an air duct of the motor vehicle.
  • vibrations of the electric motor are decoupled from the motor vehicle in order to prevent them from leading to an acoustically perceptible sound at another location, which sound can be perceived as being unpleasant by a vehicle occupant in the passenger compartment of the motor vehicle.
  • An elastic element is normally disposed between the electric motor and the housing in order to decouple the vibrations of the electric motor from the vehicle.
  • the housing comprises a recess for receiving the elastic element
  • the electric motor has a device for engaging into the elastic element.
  • a dumbbell-shaped design of the elastic element in the form of two spherical sections connected to one another by a crosspiece is typical, the device engaging into the elastic element in the region of the crosspiece.
  • the fan module is operated at high temperatures, a spring stiffness of the elastic element significantly decreases.
  • the radially protruding engagement element of the electric motor can come into contact with a periphery of the recess along the circumferential direction of the electric motor, whereby all damping is circumvented.
  • a further aim of the invention consists of specifying a production method for such a fan module.
  • a drive device for a fan module comprises an electric motor, a housing and an elastic element for fastening the electric motor to the housing in a manner which damps vibrations.
  • the electric motor has a radial engagement element for engaging into the elastic element, and the housing has a radial recess for receiving the elastic element.
  • the elastic element frames the engagement element on a radial section thereof.
  • the elastic element Due to the special design of the elastic element, the possibility that the engagement element comes into contact with a periphery of the recess is practically eliminated even in the case of the elasticity or the damping capability of the elastic element being severely compromised due, for example, to ageing, wear or high temperature. Impacts can thereby be prevented and thus the service life of the electric motor can be extended and acoustic interferences in the region of the drive module can be prevented.
  • the elastic element can be less robustly dimensioned; thus enabling a preloading to be minimized. In so doing, the damping properties of the elastic element can be improved in both the short term and the long term. Moreover, a structural load on the housing can be minimized.
  • contact surfaces between the elastic element and the engagement element or, respectively, the recess can be enlarged; and therefore a material fatigue, in particular of the elastic element, can be made less likely.
  • the elastic element is preferably formed such that a spring stiffness of the elastic element along a rotational direction of the electric motor is smaller than parallel to the rotational axis of the electric motor. Vibrations of the electric motor along the rotational direction thereof can thereby be better decoupled from the housing while at the same time a support of said electric motor in the direction of the rotational axis thereof remains rigid. As a result, a collision of a fan wheel connected to said electric motor with an air guidance duct can be prevented.
  • the elastic element can comprise a radial cut-out in order to reduce a contact surface to the recess in the circumferential direction of the electric motor. In so doing, a heat dissipating surface area of the elastic element is enlarged; thus enabling heat from the elastic element to be better released. As a result of this measure, the service life of the elastic element can be increased, in particular at high operating temperatures. On account of the same measure, the spring stiffness of the elastic element can also be decreased in the circumferential direction of the electric motor.
  • the elastic element can also be formed in such a way that a radial outer side of the elastic element is curved in order to fit closely against a section of the housing. As a result, a rolling motion of the elastic element along a radial peripheral surface of the recess is minimized on the one hand, whereby wear to the elastic element is reduced and a stiffness constant of said elastic element can be evenly maintained. On the other hand, an improved dissipation of heat from said elastic element to the housing of the drive device can thereby be realized.
  • the elastic element is formed in such a way that a periphery of the electric motor which is in the circumferential direction rests in a planar fashion against a corresponding periphery of the recess.
  • the recess can be completely filled by the vibration damper along the circumferential direction of the electric motor; and therefore a preloading of the elastic element can be reduced or omitted.
  • the stiffness constant of the elastic element in the circumferential direction of the electric motor can thereby for the most part be determined by the selection of the material or the Shore hardness of the elastic element.
  • the engagement element comprises a round metal web, which is fastened to a pole pot of the electric motor.
  • the metal web is preferably formed on one side by upsetting, the upset end being disposed between the pole pot and a flux-return ring of the electric motor. This can facilitate a simple and cost effective production.
  • the elastic element is preferably symmetrically shaped with respect to a rotation about a radius of the electric motor. An improper installation of the elastic element in an incorrect position can thereby be prevented. Additional features in the sense of a Poka Yoke strategy (“fail safe principle”) can be omitted where appropriate, which can lead to further cost reductions.
  • a cover which axially closes the housing is provided in one embodiment, the elastic element being held in the axial direction in a form-fitting manner between a periphery of the recess and the cover. In this way, the electric motor can be easily mounted in and dismounted from the housing.

  • An elastic element 130 is provided for mounting the electric motor 115 in relation to the housing 120 or the cover 125 .
  • the elastic element 130 is typically manufactured from a plastic or rubber material.
  • a recess 135 for receiving the elastic element 130 is provided on the housing 120 , wherein along a rotational axis 140 of the electric motor 115 , the recess 135 is closed at the top by the cover 125 and is open towards the inside in the radial direction.
  • the elastic element 130 is formed in such a manner that it rests on five sides against peripheries of the recess 135 , while the sixth side faces the electric motor 115 in the radial direction.
  • a plurality of elastic elements 130 having corresponding recesses 135 and engagement elements 145 is typically distributed around a circumference of the electric motor 115 . Not all of the elastic elements 130 have to thereby be at the same height with respect to the rotational axis 140 of the electric motor 115 .

  • a section of a flux-return ring 210 of the electric motor 115 is depicted to the left of the upset end of the steel wire 145 .
  • the flux-return ring 210 prevents the steel wire 145 from slipping to the left into the electric motor 115 .
  • FIG. 3 shows an elastic element 300 corresponding to the elastic element 130 from FIG. 1 .
  • the elastic element 300 can particularly be used on the drive device 110 from FIG. 1 in conjunction with the engagement element 145 depicted in FIG. 2 .
  • a coordinate system displays, in relation to the rotational axis 140 of the electric motor 115 in FIG. 1 , a radial direction x, an axial direction y and a circumferential direction z.

  • Limitations of the elastic element 300 along the y-direction correspond again to peripheries of the recess 135 or of the cover 125 .
  • the lateral surfaces of the elastic element 300 oriented in the z-direction are reduced in size in that four round cut-outs were introduced on the corners of the positive and negative y- and z-directions respectively along the x-direction.
  • the resulting cut surfaces can contribute to enlarging a surface area of the elastic element 300 in order to facilitate a heat dissipation, which, for example, can result in the elastic element on account of the damping behavior of the same.
  • FIG. 4 shows an elastic element 400 on an electric motor 115 from FIG. 1 .
  • the information is displayed with the viewing direction substantially from the rotational axis 140 of the electric motor 115 radially outwards.
  • a coordinate system corresponding to that of FIG. 3 facilitates the orientation.
  • only two cut-outs have been introduced here along the x-axis, which form in a concave manner the peripheries of the elastic element 400 located in the z-direction.

  • a transition between the slot-shaped recess 305 and the adjoining outer periphery of the elastic element 600 is rounded off on a side of said elastic element 600 that is radially remote from the electric motor.

  • a lug is stamped from the pole pot 205 of the electric motor 115 and bent towards the outside, wherein lateral sections of the lug are bent downwards in the axial direction in the embodiment depicted.
