Definitions
- the invention relates to a motor vehicle door lock, with a locking mechanism, and with a motor drive, wherein the motor drive is a downstream transmission follows, and wherein the transmission in normal operation and in emergency operation with different torques on the Locking mechanism works.
- the invention is based on the technical problem, a Motor vehicle door lock of the initially described Design to develop so that a secure Opening of the locking in emergency operation succeeds, and indeed at significantly reduced in comparison to the prior art Effort.
- the transmission is a clutch which, in the course of a direction constant movement of the motor drive load-dependent for a change the transmission from normal operation to emergency operation provides.
- the clutch ensures that depending on the output side load the gearbox its transmission ratio changes, namely from normal operation to the emergency mode (and back).
- the clutch may have two or more transmission members releasably connect with each other.
- Gear links are on the one hand to a Ratchet gear member and on the other hand a drive gear member.
- the ratchet transmission link is - nomen est omen - with the ratchet and the drive transmission member with connected to the motor drive.
- the spring leg in particular plastic spring leg to train. That is, the spring leg is as a plastic injection molded part formed, which with the ratchet gear member is connected. It has the clutch via a into a recess of the drive gear member non-positively engaging nose. Will the ratchet gear member blocked in an emergency, leaving the nose off a certain torque, the relevant recess of the Drive transmission member. This is still going on long continue until the freewheel for the already mentioned Blockade provides.
- the gearbox can be used as a planetary gear Sun gear, planetary gears, planet carrier and ring gear be educated.
- the drive gear member the ring gear while the ratchet gear member with the Planet carrier is identified, or vice versa.
- Of the Motor drive in turn likes the sun gear or working a planetary gear.
- a motor vehicle door lock which has an electrical opening both in the Normal and emergency operation possible.
- a mechanical redundancy is express not mandatory. That is, even when blocked Locking his opening succeeds electrically and does not have to be intervened manually.
- the increased load case is detected automatically because the clutch load-dependent for a separation of the previously non-positively connected two gear members provides. Uncoupling takes place automatically and The clutch automatically switches to another gear ratio to open the locking mechanism.
- Direction of rotation of the motor drive not, it finds So a direction constant movement instead. That is with Cost advantages associated because of the engine and in particular the electronics controlling it only for turns in one Direction must ensure. This is the main advantages to see.
- a motor vehicle door lock is shown, which indicated by an only in Fig. 2 Lock 1, 2 from a catch 1 and a pawl second features.
- the locking mechanism 1, 2 does not work with one Lock bolt shown together.
- the illustrated motor vehicle door lock can be motorized with the help of a Drive 3, 4, 5 open.
- the Drive 3, 4, 5 from an electric motor 3, an output shaft with screw 4 and a driven pulley 5 together.
- the worm 4 works on the driven pulley 5 in the in Fig. 2 illustrated direction of rotation, in which it is in in the view of FIG. 2, a clockwise movement is.
- the motor drive 3, 4, 5 is followed by a downstream Transmission 6, 7, 8, 9, which in the embodiment and not limiting as a planetary gear 6, 7, 8, 9 is formed is.
- the planetary gear 6, 7, 8, 9 has via a sun gear 6, three planet wheels 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, as shown in FIG Fig. 2 due to its from the motor drive 3, 4, 5th caused the pawl 2 clockwise movement lifts so that the catch 1 is released and the Locking pin releases. An associated motor vehicle door can be opened.
- the power flow in this normal operation is the same designed that the sun gear 6 together with the planetary gears 7, the planet carrier 8, the ring gear 9 and the Cam 10 a quasi-rigid assembly 6, 7, 8, 9, 10th form.
- This quasi-rigid assembly 6, 7, 8, 9, 10 is in total on 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 for a change of the transmission 6, 7, 8, 9 from normal operation ensures emergency operation.
- the coupling 11 in the context of the embodiment via a spring leg 11a and a Nose 11b on this spring leg 11a.
- the nose 11b attacks 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 planetary gear 8 operates on the ratchet 1, 2 and thus assumes the function of a ratchet gear member 8.
- the clutch 11 now ensures that the two aforementioned gear members 8, 9 releasably connected to each other are.
