Definitions
- the invention relates to an electric motor drive according to the preamble of claim 1.
- Electromotive drives are used in motor vehicles among other things in window regulators, drives for sliding doors or Wegversteliitch use.
- An example of such a drive is shown in DE 201 11 575 U1.
- Known electric motors in the form of Gleichstabstabankermotoren have a pole pot, which consists of metal and is made by deep drawing in several drawing stages.
- the magnets of the stator are fastened by means of clamps or adhesive bonding in the pole pot, which can be produced very precisely, in order to avoid parasitic air gap losses in the region of the contact surfaces of the magnets with the pole pot.
- Known pole pots are in cross section not adapted to the different radial flux densities (saturation in iron).
- Magnetic shells attached to the ends of the tube, the rotor shaft bearing elements.
- the elements supporting the rotor shaft are aligned with respect to the tubular element.
- Object of the present invention is to develop an electric motor drive for a motor vehicle according to the preamble of claim 1.
- means are provided by which the rotor shaft bearing elements are aligned and centered with respect to the magnetic shells.
- the magnets (exciter magnets) of the tube element are applied / injected as bonded in plastic magnetic particles to the inside of the tube element.
- plastic-bonded rare earth magnets are used.
- the pipe element from two half-shells.
- it can then be provided to connect these half-shells on the injected and the magnetic poles forming plastic material.
- a positive, non-positive or frictional connection technique of the half shells can be used.
- the rotor shaft overlying and with respect to the magnetic shells aligning and centering elements are preferably formed as plastic parts and form a bearing flange and a transmission flange. These have the provided bearing elements.
- Bearings and gearbox flange can be made in one or two parts. With a one-piece design of the flange, the bearing for the rotor shaft is integrated directly into this bearing. In a two-part design of the flange, the bearing for the shaft is inserted in an additional flange or a separate usable Kalottenlagersitz in the flange. In addition, electronics in the form of a circuit board can also be accommodated in the flange. To accommodate the bearing, this board then has a recess in the region of the motor shaft bearing.
- the inventively provided which consists of plastic-bonded magnetic elements receiving pipe element does not have to be a precision manufactured molded part - the wall thickness of the steel pipe or the pipe halves is adapted to the magnetic flux.
- the tubular body thus has to carry the function of optimum flow control and the injected, bound in plastic magnets.
- the necessary accuracy of the inner magnetic jacket to the armature is transmitted to the injected magnetic body, which frontally a form-fitting with a corresponding counter-mold on the element (bearing flange, gear flange) cooperating Having alignment structure.
- the end faces of the plastic-based magnetic shells can be designed conically or stepped as a form paragraph.
- the elements terminating the tube element and supporting the shaft have a correspondingly shaped counter contour, by means of which the elements and thus the position of the rotor are aligned centrically exactly with respect to the magnetic shells.
- the Rohrelemen For secure attachment of the injected magnetic shells on the pipe inner wall, the Rohrelemen according to a preferred embodiment of the invention undercuts or embossments on. With appropriate design of this form embossing results in addition to an adhesion of the magnetic plastic an additional positive fastening.
- seals are used in the bearing and the transmission flange. Also seals may be provided with a two-component plastic between the bearing or gear flange and the tubular element. In addition to the sealing results in an acoustic decoupling - the engine according to the invention runs quieter.
- the rotor shaft has a worm at one end.
- a cable drum of a cable window lifter can then be driven via this worm via a worm wheel and optionally a further spur gear stage.
- other adjusting devices within a motor vehicle can be actuated via the worm together with the worm wheel.
- the rotor shaft is preferably mounted at both ends of the rotor armature. Accordingly, the bearing also have the rotor shaft outgoing gear flange per a bearing. The sitting beyond the gearbox flange screw is preferably stored on the fly in a short version. In a longer worm, a further bearing support of the shaft can be additionally provided.
- Bearing and transmission flange are preferably held together by two running outside the tubular element Stahlklammem.
- gear and bearing flange Befest Trentsnieschen, in which attack the ends of the brackets respectively.
- the tubular element is flattened precisely in the areas in which the ends of the bearing shells lie opposite one another.
- the connection between the bearing and gear flange via the steel clamps then takes place in this area.
- the steel clamps then not only hold the two flanges at the respective ends of the tube element, but the steel chambers also increase the flow cross-section in this exposed region of the tube element (high saturation induction).
- the steel brackets may be formed at the ends as hooks, which engage in corresponding Nieschen the bearing and / or transmission flange.
- each of the brackets as a steel strip, wherein the ends of the bands passed through a respective slot opening in the bearing and in the gearbox flange and the protruding ends are deformed.
- Figure 1 shows the drive according to the invention with a worm in
- FIG. 2 shows the tubular element with magnetic shells and anchors
- FIG 3 shows the tube element with a screw attached to the rotor shaft and a bearing flange together with the electronic unit.
- FIG. 4 shows the article according to FIG. 3 without tubular element
- FIG. 1 shows the drive according to the invention in an external view.
- a mounted in a bearing and a gear flange 1, 2 rotor shaft 4 has at one end a screw 5, which drives via a worm wheel 6 and a downstream spur gear not shown a cable drum of a cable window lifter.
- the bearing flange 1 additionally has an electronics unit 7 with plug connection 8.
- the plastic existing bearing and gear flanges 1, 2 are each mounted on the front end of a surrounding anchor, not shown here tubular element 3 and are held by two with their angled ends in Befest Trentsnieschen 10, 11 engaging Stahlklammem 9.
- the flanges 1, 2 have not shown and the rotor shaft 4 overlapping elements in the form of sliding or rolling bearings.
- the bearing points of the rotor shaft 4 are marked with A and B.
- the pipe element is formed as a flattened on two opposite sides of tube 3 made of steel ( Figure 2).
- Magnetic shells 13, 14, which consist of a magnetic material bonded in plastic, are attached to the inner concave regions between the flattenings 12 by means of a injection molding process.
- the outer region of the tube is provided with embossments 15 which provide an additional grip on the inside of the tube 3 the sprayed magnetic shells.
- a rotor 16 mounted on the armature 16 acts in a conventional manner with the magnetic shells 13, 14 together.
- FIG. 3 shows the tube 3 with the two injected magnetic shells 13, 14, the armature 16, the rotor shaft 4 and the worm 5
- Gear flange 2 of Figure 1 is missing in this illustration.
- FIG. 3 likewise shows the two steel clamps 9 flanking the tube 3 on the flattened sides 12. The ends of the clamps 9 cooperate per side with one fastening lug 10, 11 on the bearing or gear flange 1, 2.
- one of the attachment noses 10 is on the bearing flange 1 played.
- the attachment of the bearing and the gear flange 1, 2 described here by means of the steel brackets 9 on the tube 3 is also shown in Figure 10.
- the two steel clamps 9 according to FIG. 10 are combined to form a bracket 22, the central part of which comprises the rear bearing part 1.
- the front ends of the bracket act as in the variant of Figure 10, each with a Befest Trentsniesche 11 in the transmission flange 2 together.
- the tube 3 has in the region of the two opposite flats 12 each have a recess 25, in which the steel bracket 9, the bracket 22 and the steel strip 23 is inserted.
- the recess is dimensioned such that the top of steel clip 9, bracket 22 or steel strip 23 is flush with the flattening.
