Definitions

  • the invention relates to a sliding door for a motor vehicle, with at least one guide device, and with a braking device.
  • the guide device serves to be able to move the sliding door between its closed and opened position.
  • the guide device may comprise one or more guide rollers guided displaceably along a guide track and connected to the sliding door. The movement of the sliding door can be done manually and / or by motor.
  • the braking device is coupled to a force and motion transmission device which cooperates with the guide track such that the sliding door can be locked relative to the guide track by means of the braking device.
  • This lock is triggered by a mechanical or electrical signal.
  • a mechanical signal can be done for example by a Bowden cable.
  • the electrical signal can be represented by, for example, a servomotor.
  • a certain (mechanical or electrical) signal it is therefore necessary that a certain (mechanical or electrical) signal must be present in order to be able to decelerate or lock the sliding door at any position.
  • This signal dependence of the known braking device encounters limits in practice. For example, this does not cover cases in which the sliding door is to be decelerated or prevented on a slope, that the open sliding door automatically transitions to its closed position.
  • the invention aims to provide a total remedy.
  • the invention is based on the technical problem of further developing such a sliding door so that the effect of the braking device is not necessarily coupled to a specific signal.
  • the invention proposes in a generic sliding door for a motor vehicle, that the braking device is acted upon by a spring unit continuously and thereby generates a permanent acting on the guide device braking torque.
  • the braking device exerts a permanently acting braking torque on the guide device.
  • This has the consequence that, for example, along a guideway slidable and connected to the sliding door guide rollers are decelerated continuously or the sliding door can be moved only after overcoming this braking torque.
  • the braking torque advantageously so that the sliding door in any case performs no automatic movement and maintains their once occupied position. This is true even if the associated motor vehicle is parked, for example, on a slope or downhill section and to prevent the sliding door is automatically transferred after opening an associated motor vehicle door lock in its open position or in the closed position due to the weight forces acting on it.
  • the braking torque will thus be adapted to the maximum of the associated motor vehicle to be overcome slope and the total weight acting on the sliding door here. In any case, this thus prevents automatic movements of the sliding door.
  • the braking device is advantageously equipped with a brake disc.
  • the brake disc is acted upon by the spring unit and in turn is coupled to the guide device.
  • the brake disc is regularly rotatably, but axially displaceable with the Guiding device connected. This makes it possible to compensate for any wear of the brake disc or the pressure plates easily, because the function of the braking device ultimately does not depend on the strength or thickness of one hand, the brake disc and on the other hand, the two pressure plates.
  • the spring unit ensures that the necessary and adapted to the previously described maximum slope brake torque acts on the guide device.
  • the pressure plates are advantageously based on the one hand on a housing, for example a brake housing and / or a clutch housing and / or a transmission housing of a drive unit, and on the other hand on the spring unit.
  • the spring unit ensures that at least one pressure plate is acted upon axially in the direction of the brake disc, which is clamped by this process between the two pressure plates, with the predetermined by the spring unit braking torque. This braking torque consequently depends on the design of the spring unit or its spring constant.
  • the described sliding door can be moved both manually and by motor.
  • the guide device is equipped with the drive unit, which essentially consists of a drive motor, a drive worm connected to the drive motor and a gear connected to the drive motor, which of course is not mandatory.
  • the (electric) drive motor is designed so that it can easily move the sliding door back and forth, thus overcoming the permanent acting on the guide device braking torque.
  • the brake device is arranged on the drive worm connected to the drive motor or the downstream gear is.
  • the braking device may be integrated into the drive worm and / or flanged to it.
  • the drive worm and possibly the drive motor and the braking device form a compact structural unit.
  • the spring unit is advantageously clamped between the brake device or the brake disk realized there and a brake housing. That is, the spring unit is supported on the one hand on the brake disc and on the other hand at the bottom of a receptacle in the brake housing.
  • the spring unit is a spiral spring.
  • the spring unit or the coil spring may surround the drive worm in part like a ring. That is, the drive worm or a drive shaft connected to the drive worm dives at least partially with its head into the surrounding coil spring or spring unit.
  • a sliding door for a motor vehicle which is equipped with a special braking device. Because the question brake device ensures that the guide device for the sliding door is permanently decelerated or acts on this guide device a continuous braking torque. The size of this braking torque can be adjusted via the spring unit or its spring constant and is designed so that the sliding door under all (geographical) circumstances remains in their current position. This position is maintained regardless of any weight force acting on the sliding door on an uphill or downhill path.
  • the optional drive motor of the drive unit is designed so that all forces acting on the sliding door forces, such as inertia, friction, etc. but in particular the permanently acting braking torque of the braking device are overcome.
  • the invention prevents both unwanted opening and closing movements of the sliding door.
  • a sliding door 1 for a motor vehicle 2 is shown.
  • the sliding door 1 can be transferred from a dash-dotted lines indicated closed position to an open position, as indicated. This can be done manually or by motor. To do this, a motor vehicle door lock 3 assigned to the sliding door 1 must first be unlocked and opened.
  • the sliding door 1 is moved into the open and the closed position with the aid of a drive unit 4, 5, 6, 7 to be recognized in FIG. 2.
  • the drive unit 4, 5, 6, 7 has an electromotive drive motor 4, a drive motor 4 following gear 5 and ropes 6 and finally deflection 7 for the two ropes 6.
  • the sliding door 1 is connected to the two cables 6, the respective length of which is changed by means of the drive motor 4 including the transmission 5 with the interposition of a cable drum to be recognized in FIG.
  • the sliding door 1 is reciprocated along a guideway 8 indicated only in FIG.
  • 8 guided rollers are attached to the sliding door 1 in the guideway.
  • This guide device 4, 5, 6, 7, 8 is of course also then Use, for example, if the drive motor 4 should have failed and the sliding door 1 manually (emergency) must be pressed.
  • FIG. 1 Details of the drive unit 4, 5 are shown in FIG.
  • a clutch actuator 5a can be seen which has a translationally displaceable boom 5b, which in turn acts on a clutch lever 5c of the gearbox 5.
  • the transmission 5 is a planetary gear.
  • the drive motor 4 When the drive motor 4 is energized, its rotation is transmitted to a drive worm 9 provided on the output side of the drive motor 4, which drives the transmission 5 and thus the cable drum already provided on the output side of the transmission 5. Since the planet carrier of the transmission 5 is blocked by a locking lever 10, the rotational movement introduced via the drive motor 4 is transmitted to a ring gear of the planetary gear, which in turn is connected to the cable drum. As a result From this, the respective cable 6 is wound up and unwound, so that the sliding door 2 performs the mentioned movement in its closed position or open position.
  • a sensor is arranged, with the aid of which the speed and direction of rotation of the cable drum can be detected and evaluated.
  • the locking lever 10 With the aid of the clutch actuator 5a, the locking lever 10 can be brought into engagement and out of engagement with the planet carrier of the transmission 5.
  • the cable drum and with it the sliding door 1 by means of the drive motor 4 is reciprocated. If, however, the locking lever 10 is not in engagement with the planet, so the sliding door 1 can be moved manually. Because for this case rolls. the non-rotatably connected to the cable drum ring gear on the planet gears, so that the planet carrier is moved with.
  • the sun gear connected to the drive motor 4, like the drive motor 4, remains unaffected by this movement initiation. In this way, the manual movement of the sliding door 2 is not unnecessarily difficult.
  • the locking lever 10 is associated with a spring, not shown, which loads the locking lever 10 in its "uncoupled” position.
  • the locking lever 10 is acted upon by the coupling actuator 5a via the boom 5b or the clutch lever 5c. So you will always proceed when the sliding door 1 is to be moved by motor with the help of the drive motor 4.
  • the spring ensures the "uncoupled” position of the locking lever 10, so that the sliding door 1 can be moved manually with reduced force, because the drive motor 4 does not need to be moved.
  • a braking device 11 which is shown in FIG. 5 and which operates on the guide device 4, 5, 6, 7, 8.
  • the braking device 11 is shown in Fig. 4 on the drive screw 9 on the output side of the drive motor 4 and the gear 5 flanged or end of this drive section 9 is arranged. That is, the braking device 11 is located on the drive screw 9 beyond an engagement region 12, within which the drive screw 9 acts on the gear 5 designed as a planetary gear.
  • the design is such that the braking device 11 is acted upon by a spring unit 13 and thereby produces a permanently acting on the guide device 4, 5, 6, 7, 8 braking torque.
  • the strength of the braking torque essentially depends on the spring constant of the spring unit 13 designed as a spiral spring or helical spring 13.
  • the drive worm 9 engages in an associated brake housing 14.
  • the drive screw 9 passes through a brake housing 14 upstream bearing ring 15, which provides for the storage of the drive screw 9 and in this context as, for example, ball bearings, roller bearings or as a sliding bearing is executed.
  • the drive screw 9 is rotatably mounted on a drive shaft 16, which in turn is connected to the output side of the drive motor 4. It can be seen that the drive worm 9 extends to said bearing ring 15, whereas the drive shaft 16 is mounted in the bearing ring 15 and passes through this.
  • a brake disk 17 and two pressure plates 18 are realized in the braking device 11.
  • the brake disc 17 is arranged between the two pressure plates 18.
  • the brake disk 17 can be displaced axially on the drive shaft 16 or the drive worm 9, but is non-rotatably connected to the drive shaft 16 in question. In this way, any wear on the brake disc 17 and the two pressure plates 18 can be compensated for without this changing anything on the functionality of the braking device 11.
  • the other pressure washer 18 placed on the housing side is received in the transmission housing 14, in an associated guide groove 19.
  • said pressure plate 18 On its side facing away from the drive shaft 16 or the drive worm 9, said pressure plate 18 is acted on by the spring unit or spiral spring 13. That is, the spring unit or coil spring 13 is supported on the one hand on the said pressure plate 18 and on the other hand on a stop ring 20 in the transmission housing 14 from.
  • the right pressure plate 18 is spring-loaded in the direction of the brake disk 17 and the brake disk 17 is braced in total between the two pressure plates 18.
  • the right or housing-side pressure plate 18 can be moved axially within the guide groove 19.
  • the spring force built up by the spring unit or coil spring 13 thus ensures that the right pressure plate 18 and the brake disk 17 axially against the left pressure plate 18 pressed like a floating disc brake in a car or motorcycle. Consequently, the brake disk 18 can rotate only when the torque acting on the drive shaft 16 or the drive worm 9 exceeds the braking torque built up in this way by the spring unit or the spiral spring 13.
  • the spring unit or the spiral spring 13 at least partially surrounds the drive worm 9 or the drive shaft 16 arranged in the interior of the drive worm 9.
  • the two pressure plates 18 and the brake disc 17 and finally the coil spring 13 are each arranged coaxially to an axis A, which also represents the axis of rotation for the drive shaft 16 and the drive screw 9.
  • the two pressure plates 18, the brake disc 17, the spring unit or coil spring 13, the brake housing 14, the drive screw 9 and arranged in the interior of the drive screw 9 drive shaft 16 are each rotationally symmetrical to just this axis A. This provides a particularly compact design.
