Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, and with a motor drive, wherein the motor drive is followed by a downstream transmission, and wherein the transmission operates in normal operation and in emergency operation with different torques on the locking mechanism.
  • the invention is based on the technical problem of developing a motor vehicle door lock of the design described above so that a secure opening of the locking mechanism in emergency operation succeeds, and in comparison with the prior art significantly reduced effort.
  • a generic motor vehicle door lock according to the invention is characterized in that the transmission is designed as a planetary gear and has a coupling which provides load-dependent in the course of a direction constant movement of the motor drive for a change of the transmission from normal operation to emergency operation.
  • the clutch thus ensures that, depending on the output load, the transmission changes its transmission ratio, namely from normal operation to emergency operation (and back).
  • the coupling can releasably connect two or more gear members together.
  • These two gear members are on the one hand a locking gear member and on the other hand a drive gear member.
  • the ratchet transmission link is - nomen est omen - connected to the ratchet and the drive gear member with the motor drive.
  • the clutch itself may be connected to one of the two gear members. Usually takes place at this point, a connection of the coupling to the ratchet gear member. In principle, however, the coupling can also be connected to the drive gear member.
  • the invention proposes in detail that the drive transmission member is blocked in disengaged clutch in emergency mode. Because in such a case, the ratchet gear member experiences so by external circumstances a blockage and must be applied according to the invention with the increased torque. This is done in such a way that the transmission switches over to the desired other transmission ratio when (additionally) the drive transmission member is blocked. In most cases, a large reduction ratio is selected at this point in order to be able to generate torques on the output side or on the ratchet gear member which are able to overcome the blockage torque associated with the emergency.
  • the coupling with a spring leg, in particular plastic spring leg. That is, the spring leg is formed as a plastic injection molded part, which is connected to the locking gear member.
  • the clutch has a non-positively engaging in a recess of the drive gear member nose. If the locking gear member is blocked in an emergency, leaving the nose from a certain torque, the relevant recess of the drive gear member. This continues to rotate until the freewheel provides the aforementioned blockage.
  • the transmission is designed as a planetary gear with sun gear, planet gears, planet carrier and ring gear.
  • the drive gear member is the ring gear
  • the ratchet gear member is identified with the planet carrier, or vice versa.
  • the motor drive in turn may work on the sun gear or a planetary gear.
  • a motor vehicle door closure which allows electrical opening in both normal and emergency operation.
  • a mechanical redundancy is expressly not required. That is, even when blocked Locking succeeds his opening electrically and does not need to be intervened manually.
  • the increased load case is automatically detected because the clutch load-dependent ensures a separation of the previously non-positively interconnected two gear members.
  • the decoupling takes place automatically and the clutch automatically switches to a different gear ratio to open the locking mechanism.
  • the direction of rotation of the motor drive does not change, so there is a direction constant movement. This is associated with cost advantages, because the motor, and in particular the electronics controlling it, only has to provide for unidirectional rotation.
  • the main benefits are the main benefits.
  • a motor vehicle door lock is shown, which has a purely in Fig. 2 indicated ratchet 1, 2 of a rotary latch 1 and a pawl 2 has.
  • the locking mechanism 1, 2 does not work with one Lock bolt shown together.
  • the illustrated motor vehicle door lock can be motorized by means of a drive 3, 4, 5 open.
  • the drive 3, 4, 5 consists of an electric motor 3, an output shaft with worm 4 and a driven pulley 5 together.
  • the worm 4 works on the driven pulley 5 in the in Fig. 2 shown direction of rotation, in which it is in the view Fig. 2 is a clockwise motion.
  • the motor drive 3, 4, 5 is followed by a downstream gear 6, 7, 8, 9, which in the embodiment and not limiting as a planetary gear 6, 7, 8, 9 is formed.
  • the planetary gear 6, 7, 8, 9 has a sun gear 6, three planet gears 7, a planet carrier or web 8 and a ring gear. 9
  • a cam 10 or switching cam 10 Connected to the planet carrier 8 is a cam 10 or switching cam 10, which, as shown in FIG Fig. 2 as a result of his caused by the motor drive 3, 4, 5 clockwise movement, the pawl 2 lifts, so that the catch 1 comes free and releases the locking pin.
  • An associated motor vehicle door can be opened.
  • the power flow in this normal operation is designed so that the sun gear 6 together with the planetary gears 7, the planet carrier 8, the ring gear 9 and the cam 10 form a quasi-rigid assembly 6, 7, 8, 9, 10.
  • This quasi-rigid assembly 6, 7, 8, 9, 10 is a total of the driven pulley 5 of the screw 4 in Spins offset.
  • the rotational movements of the motor drive 3, 4, 5 are thus transferred 1: 1 to the cam 10.
  • the transmission 6, 7, 8, 9 has a clutch 11, which in the course of a direction constant movement of the motor drive 3, 4, 5 load-dependent ensures a change of the transmission 6, 7, 8, 9 from normal operation to emergency operation ,
  • the coupling 11 in the exemplary embodiment has a spring leg 11a and a nose 11b on this spring leg 11a.
  • the nose 11b engages non-positively in a recess 12 of the ring gear 9 a.
  • the ring gear 9 is connected to the drive 3, 4, 5, it represents a drive gear member 9.
  • the planet gear 8 operates on the ratchet 1, 2 and thus assumes the function of a ratchet gear member 8.
  • the clutch 11 provides now that the two aforementioned gear members 8, 9 are releasably connected together.
  • the freewheel 13 allows such rotations of the ring gear or drive gear member 9. If, on the other hand, it comes to an emergency and a relative movement between the ratchet gear member or planet carrier 8 and the drive gear member or ring gear 9, then the freewheel 13 blocks the drive gear member or ring gear 9. As a result, the previously with the ring gear 9 roll co-rotating planet gears 7 in its interior.
  • the motor drive 3, 4, 5 operates in this emergency, ie via the sun gear 6 and the planetary gears 7 on the planet 8 with stationary ring gear 9. This causes an increased reduction or increased torque on the cam 10. This causes the Lock 1, 2 is opened.
