Definitions

  • the invention relates to a device for fastening an electric motor, in particular a blower motor according to the preamble of the independent claim.
  • Blower motors for heating and air conditioning systems which are used, for example, in motor vehicles, are generally decoupled from the vehicle in terms of vibration technology in order to reduce the transmission of structure-borne noise from the motor or the blower unit to the body and thus to the interior of the vehicle.
  • the main source of the undesirable vibrations of DC motors are motor unbalance and commutation within the motor.
  • Commutation occurs when the copper windings of the armature carry current while the motor is operating. During each rotation of the armature shaft, current is conducted once in each direction through the existing windings of the motor. The current flow in the windings generates a reaction under the influence of a permanent magnetic field, which is passed on as a torque pulse.
  • Elastic damping elements can be inserted between the adapter part receiving the motor and the actual motor mount, which are intended to ensure decoupling of the motor mount from the motor vibrations.
  • rubber in the form of appropriately shaped rubber elements is inserted between the engine and the motor housing, in the flange or between the flange and a support element of the air conditioning system
  • DE 43 34 124 AI discloses a device for receiving an electric motor, which achieves a particularly low-vibration and thus noise-damping effect by virtue of the fact that between the inner walls of this receiving device and the ones facing it
  • At least one elastic damping element is arranged on the outer walls of the motor housing and is supported on the mutually facing walls of the receiving device and the motor housing.
  • These elastic damping elements which in a preferred embodiment of the device of DE 43 34 124 AI are correspondingly shaped rubber elements, mean increased assembly and material expenditure, which unnecessarily increases the cost of such a device.
  • DE 196 52 328 C2 discloses a noise-insulated holding device for an electric motor, in which the electric motor is inserted into a first plug-in receptacle, which serves as an adapter part, and is axially secured by latching hooks.
  • This plug-in receptacle has radially pivotable tongues in the manner of spiral springs distributed over its outer circumference. On these tongues radially outwardly projecting webs are molded onto the correspondingly shaped, sound-absorbing intermediate parts, such as rubber caps, for example, which can be plugged into the clamping connection.
  • the adapter part is inserted into a larger motor mounting part when mounting the bracket of DE 196 52 328 C2. If the electric motor with its housing is now inserted into the adapter part, the tongue-like spiral springs are pressed outwards, so that they engage in corresponding fixing openings of the motor mounting part, mediated via the noise-insulating intermediate parts.
  • the device according to the invention for fastening an electric motor with the features of the independent claim has the advantage that a simple assembly of the motor is achieved by means of fastening hooks without an adapter with simultaneous decoupling by rubber damping elements.
  • a plurality of spring-elastic holding elements of a receiving housing which serves as a motor housing, act directly on the electric motor, so that there is no need to use adapter housings or intermediate housings.
  • Holding elements of the device according to the invention are advantageously provided at least in places on the side facing the engine with an elastic material, so that there is additional vibration and noise damping due to the elastic properties of this material.
  • the elastic material with which the spring-elastic holding elements are provided on their side facing the motor is a thermoplastic Elastomer. This can be applied in a simple and therefore advantageous manner directly to the resilient holding element, for example by a two-component spraying process.
  • a device according to the invention which is particularly light in terms of installation weight and easy to produce is obtained if both the motor housing, that is to say the receiving housing for the motor, and the spring-elastic holding elements are made from a plastic, for example from a polypropylene plastic.
  • the housing parts can be produced in an injection molding process, so that it is also possible in a simple manner to form additional components and carrier elements for engine components on the housing.
  • the resilient holding elements for the motor can be formed in one piece, preferably in one piece, in a tongue-like manner directly on the pot-shaped receiving housing.
  • the holding element can pass directly into the wall of the receiving housing at its lower end and remains movable with its second axial end relative to the housing wall, so that a corresponding bending stress results on this tongue-like spring element, via which the motor is fixed in the receiving device can.
  • a secure fastening of the motor in the motor housing results especially when the spring-elastic holding elements have a hook-shaped fastening element at their free ends, for example in the form of locking lugs, which in Appropriate recesses and contact edges of the electric motor or attack.
  • the electric motor can be secured in a simple but reliable manner in the axial direction against slipping.
  • the holding elements engage with their hook-shaped free ends on an end face of the electric motor.
  • the electric motor can be inserted into the motor housing in both possible orientations, which would expand the range of applications of the motor mount.
  • the hook-shaped ends of the resilient holding elements can grip around the end of the pole ring, thereby axially securing the motor.
  • the motor is thus attached directly to the motor housing with the least amount of parts and assembly work using fastening hooks using elastic damping elements.
  • the electric motor can also be secured against radial rotation by means of stop webs which are mounted in the bottom region of the pot-shaped receiving housing and point into the housing and engage in corresponding openings in the electric motor.
  • stop webs are also covered with an elastic material, such as a thermoplastic elastomer. The last method simplifies the manufacture of the fastening hooks.
  • additional elastic supports for radially fixing the motor can be attached to the inside of the motor housing.
  • an elastic ring or a plurality of molded-on beads made of an elastomer can occupy the inner circumference of the receptacle in a circle and support the electric motor against the housing wall.
  • a good radial fixation of the motor in the motor housing results if a plurality, typically three or four, of axially attached to the inner wall of the receiving housing, elastic decoupling elements are provided, which minimize sound and vibration transmission of the motor to the housing.
  • These radial decoupling elements can also advantageously be molded directly onto the rigid wall of the motor housing.
  • a particularly advantageous embodiment of the device according to the invention results if the radial decoupling elements running axially in the receiving housing are formed directly on the resilient holding elements. This functional combination of axial and radial decoupling is very useful in terms of production technology and enables reliable decoupling of the motor housing from the motor with relatively simple means when fastening the motor in the receiving housing and a reduced manufacturing effort.
  • the resilient holding elements and the axially aligned areas of the inner wall of the receiving housing are covered with elastic material that decouples the motor and the motor housing from one another, but reliably secures the motor in the housing.
  • the device according to the invention experiences a further advantageous embodiment when a counter bearing is present in the motor housing, which leads to an additional axial and radial fixation of the motor in the receiving housing.
  • the counter bearing likewise has an elastic damping element or is designed directly as such.
  • a particularly advantageous embodiment that is easy to implement is obtained if the counter-bearing is injected directly into the receiving housing.
  • the counter bearing can also be produced from a thermoplastic elastomer, which is injection molded onto the housing in a two-component injection molding process.
