    专利说明:

    The invention relates to electric actuators installed in a car's glass lifting mechanism and can be used in the automotive industry.
    The electric drive of a car's window regulator is known, comprising a housing with a screw gear installed in it, a transfer device for moving the glass and a connecting element / made in the form of a protrusion disk, interacting with the transmission device and a worm wheel, a hub mounted, and also elastic elements SD
    However, this drive has a number of drawbacks, 9 that when operating in wet conditions, not only mechanical drive parts, as well as the worm wheel and engine shaft supports, are corroded, but also connected to the housing / in particular, flanged him the electric motor, which when exposed to moisture after a short time out of service. This problem is particularly significant with electric drives for window lifters placed in the doors of the car, since a large amount of water gets through the interior of the doors when there is heavy rain or using a car wash.
    The purpose of the invention is to reduce the size, improve the protection of the worm gear, 9 moisture absorption and reduce the impact loads.
    To achieve this goal, an electric drive window of a car, comprising a housing with a worm gear installed in it, a transfer device for moving the glass, a connecting element made in the form of a disk with projections interacting with a transfer device and with a worm wheel mounted on a hub axle, as well as elastic elements, provided with a sealing sleeve mounted on the hub of the worm gear with a gap and having peripheral holes in which the said heights are located blunt connecting element, and in the last there are holes for accommodating the corresponding protrusions that are made on the worm gear / while said transmission device is made in the form of a cable drum, worn on one part of the connecting element, and the specified sealing sleeve is installed between the other part of the connecting element and the worm wheel and has at least one
    a stop mated to the latter and at least one stop on the portion facing the drum mating with the inner surface of the body.
    In this case, the drum and the connecting element are made of waterproof, predominantly synthetic material.
    The body is made of two detachable
    0 parts / between which is placed the sealing ring.
    The sealing sections of the coupling are made of a softer material / than the base.
    5 Figure 1 shows an embodiment of the electric window regulator, in partial section; Fig. 2 shows a second embodiment / section; on fig.Z. - the third option is an option, a detailed section on an enlarged scale; 4 shows a sealing sleeve / left view; 5 shows the same right view; figure 6 is a section aa in figure 4 and 5,
    5 A power window drive moves a window glass (not shown) using drive cable 1, which passes through sections within the flexible sheath and forms an endless loop. Through the hole 2 in the case 3 of the drive window lifter drive cable 1 enters inside the case. There he is wound on the drum 4 and then again out of the case through another hole (not shown).
    5 A drum 4 is driven schematically by an electric motor 5, which is flanged to the housing 3. On the shaft 6 of the electric motor 5 is mounted without the possibility of rotation of the worm to 7 /
    The external teeth are in engagement with the worm wheel 8. The axes of the shaft b of the engine and the worm wheel 8 are mutually perpendicular. The rotational movement of the worm
    5, wheels 8 through the connecting element 9 with brushes 10 are transmitted to the drum 4. The worm gear 8 is provided on its right side (FIG. 1) with several projections 11, which
    The additional recesses 12 of the connecting element 9 enter. To further transmit the forward movement to the drum 4, the latter is equipped with one or several axial recesses 13, which are interconnected through an annular recess 14 that reduces the diameter. When the electric motor 5 is turned on and off, a shock is generated on the entire window regulator as well as
    0 when the glass moves against the stop. In order to prevent this shock load and vibration transmission, an elastic element is provided in the power window drive. 15 in
    5 kind of rubber ring. Instead of reeinovogo ring or optional. rubber cylinders can be provided between the flaps on the connecting element and the protrusions inwards by the projections on the drum. The housing 3 generally consists of three parts with a bowl 16, approximately annular intermediate part 17 and a flat cover 18. Parts 16-18 of the housing 3 are glued together, screwed together or interconnected by rivets. The window lifter drive (Fig. 1) is connected through a housing cover 18 with a screw 19, which is screwed into a supporting shaft 20 rigidly connected to the housing bottom 16. The supporting shaft 20 is pressed or glued to a correspondingly fitted opening 21 of the housing bottom and therefore rests from both ends. The worm gear 18 is rotatably mounted on the support shaft 20. For this, the worm gear 8 is provided with a hub 22, which embraces the supporting shaft 20. Water can penetrate into the housing 3 through the opening 2 for the cable 1, more so when the flexible sheath is not used. This danger also exists when, instead of driving cable 1, another force transferring organ is used, for example, threaded cable or lifting rods. In these cases, the drum 4 is replaced by a drive gear that is connected to the threaded cable or toothed with a sector lifting t. For threaded cables or toothed sectors must be provided; corresponding sizes of holes in the housing. The drum 4 and the connecting element 9 are made of waterproof material, namely synthetic material. However, water must necessarily be prevented from entering into the inside of the electric motor 5, since the latter goes out of order, for example, if its collector brushes are in the water. Since the motor shaft 6 passes into the electric motor 5 without sealing, along the motor shaft 6, water can penetrate into the electric motor 5. To prevent this in a simple and economical way, a rubber sealing coupling 23 (also made of flexible synthetic material) is provided which hermetically separates the shaft containing 6 motor and Cherv to 7, the first part of the space from the containing connecting element 9 and the drum 4 of the second part 24 of the space. The rubber clutch 23 is made in the form of a disk, on one side it fits to the worm gear 8, and on the other hand to the connecting element 9. Through the recesses 25 of the sealing coupling 23, protrusions 1.1 and sections 26 of the connecting element 9 surrounding these protrusions The expansion sleeve 23 forms a movable seal between the intermediate part 17 of the housing 3 and the periphery of the worm gear 8. For this, three sealing sleeves are made around the perimeter of the sealing sleeve 23 ... 27. The first, axially extending, sealing sleeve 28 is adjacent to the shoulder 29 of the intermediate part 17. The second yft sealing sleeve 30 protrudes obliquely to the outer side into the radial clearance between the worm gear 8 and the intermediate part 17 and seals them, the third sealing lip 31 projects radially to the outer side to the groove 32 of the worm gear 8 and at. This concerns both the radial surface and the surface of the inner perimeter of the groove 32. The connecting element 9 with the help of the radial rib 33 supports the first sealing sleeve 28, therefore a seal is also formed between the worm gear 8 and the connecting element 9. As the connecting element 9 directly adjoins the drum 4, which is sealed relative to the connecting element 9 by means of a rubber ring 15, then for the worm wheel 8 it is possible to use a less corrosion-resistant material, for example th iron. Because of the larger length of the worm wheel hub 29, it is almost impossible for water between it and the support shaft 20 to enter the first part of the space. If, however, the danger of moisture penetration is still not eliminated, then a seal, not shown on the ring, with a KpyrJttiM section between the support shaft 20 and the hub 22 can be used. There is no direct rotational movement between the worm gear 8 and the connecting element 9. The connecting element 9 is gripped by the sealing sleeve 23 by the worm gear 8, therefore the jolts and vibrations are perceived by the sealing sleeve 23. Figure 2 shows a second embodiment of the window lifter drive, where the housing is detachable from parts 3 and 29, between which the sealing ring is installed. The drive window (figure 2) drive cable inside the door of the car freely laid through the respective swivel rollers, so there is no flexible sheath.
    Fig. 3 shows the connection between the sealing sleeve 23 and the connecting element 9. An axial brush 10 of the connecting element 9 enters the recess 25 of the sealing sleeve 23 (Fig. 3-6). The notches 25, respectively, are provided in one of four sectors of the seal 34 having a roughly shaped sector 23. The sections 34 are separated from each other by radial clearances 35, which extend from the center of the center section of the sealing cuffs 28, 30, 31 and continue in the corresponding radial groove 36 the same width, so that only both sealing cuffs 28 and 30 (Figures 4 and 6) remain, which ensure the adhesion of the sections 34 as a sector.
    In order to transfer the rotational moment between the worm gear and the sealing sleeve, the worm gear 8 is equipped with four hydraulic steps 2. These ribs fill the corresponding hydraulic gaps 35 of the groove 36, therefore shifted by 45 relative to the notches 25 or the ends of the connecting element 9. The torque is transmitted from worm wheel in this way through the ledges 29
    to the sealing sleeve 23, and from it through the brushes 10 to the connecting element 9. Under shock loading, the brushes 10 of the connecting element can rotate in the grooves 25 relative to the ledges 29 within the gaps, while the ledges 29 ensure the occurrence of the main deformation within the sectors in the form of sectors ( the offset of the notch 25), and the external form is largely maintained. The sealing effect of the sealing lips 28, 30 and 31 is also maintained under shock loading.
    Through the use of the invention, a compact arrangement is achieved - which allows the worm gear to be actuated by means of a worm through external ones.
    During operation, the worm gear moves relative to the rim. During this movement, a reliable seal is achieved by means of the fact that the worm gear is sealed relative to the housing by means of an elastic lip seal. The manufacture of such a lip seal is economical from the point of view of cost, which is particularly important for serial production in the automotive industry.
