Definitions

• Cable window lifters for a window that can be lowered into a window shaft of a vehicle have a guide rail arranged in the direction of movement of the window, along which a sliding element engaging on the lower window edge and connected to a drive cable of the cable window lifter is arranged so as to be displaceable in the longitudinal direction.
• the drive cable is guided to a drive unit which has a drive housing with a cable drum arranged therein for receiving the drive cable and a driver which engages in an internal toothing of the cable drum and which can be connected to a hand crank or a motor drive.
• the drive cable is usually arranged in a Bowden sleeve, which is attached to Bowden supports of the drive housing.
• the drive cable itself connects to the cylindrical surface of the cable drum and is connected to the cable drum in such a way that when the driver is actuated in one or the other direction of rotation, the drive cable is wound up and down by the cable drum, so that the cable is connected to the disc and on the carrier guided on the guide rail is moved up and down.
• FIG. 1 shows an exploded view of a cable window lifter drive with a cable drum and a bearing cover
• FIG. 2 shows a section through a cable window lifter drive that is mounted on a carrier plate of a motor vehicle door.
• the multi-tooth driver 3 has an external toothing 30 and on its end face facing away from the external toothing 30 three driver pins 31, which ensure the positive locking necessary for the power transmission with a driver gear element, not shown, mounted in the axis of the cable drum, that of one with the axis of the electric motor 11 connected drive worm of the transmission 12 is driven.
• the bearing cover 6 has two cable guide channels 64, 65 which open into openings 66, 67, where the window lifter cable inserted into a spiral groove 42 of the cable drum 4 and wound around the cable drum 4 emerges and is connected at the ends of the window regulator rails to the drivers of the window pane is.
• the drive housing 2 has fastening elements 21, 22, 23 which are screwed to fastening elements 61, 62, 63 of the bearing cover 6.
• Figure 2 shows the assembled state of the cable window drive, in which the fastening elements 21, 22, 23 and 61, 62, 63 through an opening a support plate 7 inserted and connected to each other with screws.
• the section shown in FIG. 2 through a cable window lifter drive shows that during assembly the drive unit 1 is first centered on the fastening elements (domes) 61 (and not shown 62 and 63) inserted through the carrier plate 7 when the drive housing 2 is plugged onto the bearing cover 6 before the driver toothing 30 engages in the cable drum toothing 40. Then the bearing cap 6 is put on and the connection of the drive unit 1 with the bearing cap 6 or the carrier plate 7 is established, for example, by means of a snap connection or by tightening fastening screws.
• the fastening elements domes
• 61 and not shown 62 and 63
• DE 43 19 705 C2 discloses a device for fastening a window lift motor, by means of which fastening positions arranged on the circumference of the motor housing are used to fasten the motor to the inner door panel.
• spacer sleeves are provided between the protrusions of the engine housing and the inner door panel.
• the object of the invention is to provide a cable window lifter drive which enables simplified assembly with few components and requires little space at the same time requires low tolerance requirements with regard to manufacturing accuracy.
• the cable window lifter drive according to the invention requires significantly less space on the carrier plate than conventional drives, since the design of the domes in the bearing caps outside the gear element or the cable drum can be dispensed with. There are also no three screwing operations and three sets of fastening or screw connecting elements, so that an additional material and assembly time saving is achieved.
• Another advantage of the cable window lifter drive according to the invention is the lower tolerance requirements with regard to the production, since only a bore or a recess is to be provided, and thus dependent dimensions, such as those which occur in the conventional configuration through the bores and domes, are eliminated.
• An advantageous development consists in securing the bearing cover against rotation, which is preferably designed to be form-fitting.
• a molded projection of the bearing cover which is supported on one or more elevations of the carrier plate, prevents the bearing cover from rotating in a simple and effective manner, for example when the window pane is moved against a stop.
• the clamping forces to be applied are reduced by the anti-rotation device, since without an anti-rotation device, rotation with a frictional connection between the carrier plate and the bearing cover with the correspondingly high clamping forces would have to be prevented.
• molded pins or hollows are also possible to prevent rotation, which correspond to the respective elements of the carrier plate.
• a radial seal between the drying space and the wet space on the carrier plate in order to ensure an effective seal.
• the seal can be integrally formed on the carrier plate, inserted in corresponding receptacles of the carrier plate or mounted on the carrier plate in another way.
• the shape of the radial seal is appropriate since both the gear element and the cable drum preferably have round cross sections, so that efficient protection against the ingress of moisture can be ensured by one or more radial seals.
• the radial seals can consist of known, commercially available radial shaft sealing rings or of plastic or rubber lips molded onto the carrier plate.
• the radial seal is accommodated in one of the two bearing caps, so that the sealing can take place at the most favorable point in each case.
• the elastic forces of the seal exert a clamping effect on the cable drum or the gear element, which facilitates assembly since the corresponding component is pre-fixed.
• a thread is provided on the motor axis for screwing on the bearing caps.
• Figure 1 an exploded view of a cable window drive with a multi-tooth driver, a cable drum and a bearing cap;
• Figure 2 - a section through a cable window drive, which is mounted on a carrier plate of a motor vehicle door and
• Figure 3 - a sectional view of a cable window lifter drive according to the invention.
• FIG. 3 shows a cable window lifter drive which is fastened to a carrier plate 7 and which has an electric motor 11 which drives a gear element 5 via a worm 16 and a worm wheel 17.
• a cable drum 4 is integrally formed on the gear element 5, so that the cable drum 4 is driven directly via the gear element 5. It is also conceivable and provided as a variant that the gear element 5 is connected to the separately manufactured cable drum 4 via a toothing, for example a multiple toothing, or that an intermediate piece such as the multi-tooth element 3 transmits the force.
• the gear element 5 and the cable drum 4 are mounted on a motor shaft 9, which is integrated in the bearing cap 6b, wherein of course the bearing cap 6a can also accommodate the motor shaft 9.
• the motor axis 9 can be formed by a molding process, e.g. Injection can be permanently connected to one of the bearing covers 6a, 6b by primary or forming processes or by a joining process, for example welding. Pressing or screwing in is also conceivable, provided the accuracy requirements can be met.
• the motor axis 9 protrudes according to FIG. 3 in a pre-assembly position through an opening 18 in the carrier plate 7 onto the drying room side.
• the cable drum 4 and the gear element 5 are pushed onto the motor axis 9 and held in this position by a seal 10 fastened to the carrier plate 7.
• the surface of the gear element 5 or the cable drum 4 is machined accordingly at the point at which the seal 10 rests, so that no excessive wear occurs.
• This preassembled unit comprising the bearing cover 6b, the cable drum 4 and the gear element 5 is pushed from the drying chamber side out of the bearing cover 6a onto the motor axis 9 and then fixed by a fastening means 8, here designed as a nut.
• the worm 16 with the motor 11 can already be attached to the bearing cover 6a or can only be installed after the mounting of the bearing cover 6a, 6b.
• By screwing the bearing caps 6a, 6b against each other, a clamping force is generated which fixes the cable window lifter drive on the carrier plate 7.
• the bearing cover 6a on the dry room side has an anti-rotation device 14, which is in the form of a shape of the support plate 7 and a corresponding receptacle 14.
• the bearing cover 6a is prevented by the anti-rotation device 14 from rotating about the motor axis 9 due to the reaction forces of the adjustment on the carrier plate 7.
• the anti-rotation device 14 can also be attached to the bearing cover 6b or can be provided in multiple versions.
• the form-fitting definitions of the bearing caps 6a, 6b being advantageous with regard to the manufacturing costs, the simplicity of assembly and the variety of designs.
• the seal 10 is fastened from dry to wet room in one of the bearing caps 6a, 6b.
• the contact surface of the seal 10, which is preferably designed as a radial seal, is accordingly outside the plane of the carrier plate 7 on one side of the bearing caps 6a, 6b.
• gear element 5 and the cable drum 4 which are connected to one another via a torque-transmitting element.
• This element can consist, for example, of an interposed multi-tooth driver 3 or an integrally formed toothing on the cable drum 4 and the gear element 5.
• This also gives the possibility of separately sealing both the cable drum 4 and the gear element 5 in the respective bearing caps 6a, 6b.
• only one seal should be provided.
