Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism, and with a closing / opening device with drive, wherein the closing / opening device operates on the locking mechanism.
  • Zuzieh- / opening devices for motor vehicle door locks have been used mainly in high-priced cars.
  • a particularly convenient approach is achieved because an operator only has to spend the associated door or flap in the pre-locking position and then ensures the closing device for the complete closing operation.
  • opening aids that ensure that an associated locking the motor vehicle door lock is opened by a motor.
  • An example of such an opening aid is in the DE 10 2004 052 599 A1 described.
  • the primary aim is to achieve a better comfort.
  • the known Zuzieh- / opening devices usually attack directly on the locking mechanism, which in turn is generally stored in a lock case of the motor vehicle door lock. Since the lock case is regularly bolted directly to an associated motor vehicle door, any noise from the drive of the closing / opening device on the motor vehicle door is usually transmitted by structure-borne noise. Since such a motor vehicle door regularly has more or less large cavities, There is a risk that the above-mentioned noises are amplified by any resonances. This is disadvantageous in that one usually wants to achieve increased ease of use with the closing / opening devices. However, if this ease of use is associated with an additional or disturbing noise level, this is classified by potential customers despite the achieved ease of operation as a total negative. This is where the invention starts.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock in such a way that, with constant ease of use, an improvement in acoustics is achieved at the same time.
  • the closing / opening device has an intermediate (acoustic) attenuator.
  • this damping element within the closing / opening device first of all ensures that an acoustic decoupling usually takes place between a mandatory motor of the closing / opening device and the other components. It has proved to be favorable when the attenuator is made predominantly of an elastomer or contains at least one such elastomeric plastic for acoustic decoupling.
  • the said attenuator or the elastomer used at this point is or is designed so that in particular generated by the already mentioned engine respectively electric motor frequencies are effectively suppressed.
  • said motor operates at 3000 revolutions per minute, this corresponds to a frequency of 50 Hz, which in the example case is particularly significant to dampen is. That is, the elastomer must be selected and designed so that, in particular, frequencies generated by the engine are effectively damped.
  • other interpretations are conceivable.
  • the design is such that the attenuator transmits rotational movements of the said motor of the drive to a downstream actuator.
  • the transmission of rotational movements with the help of the attenuator can be done directly or indirectly.
  • the attenuator is advantageously integrated in a drive train of the engine.
  • the attenuator generally connects two components of the output train of the engine together.
  • the attenuator In the case of the integration of the attenuator in the output line of the engine and consequently the direct transmission of the rotational movements of the motor to the actuator, it is recommended that the attenuator is designed as a dog clutch.
  • This claw coupling is generally composed of two equipped with claws respectively recordings coupling elements, of which at least one is made of an elastomer.
  • the attenuator connects two mostly separate components of the drive train of the engine together and thus transmits rotational movements of the engine in an indirect manner to the downstream actuator, it has proved to be beneficial if the attenuator is designed as a drive belt.
  • the embodiments belt and clutch are used as alternatives. In principle, however, it is also conceivable to combine both embodiments with each other.
  • the actuator is preferably around a linear actuator.
  • the drive is composed at least of the already mentioned motor or electric motor and the actuator or the linear actuator.
  • a particularly compact and functional embodiment is characterized in that the motor and the actuator are arranged at an angle, in particular at right angles, to one another.
  • the output train of the engine or its output shaft usually has a non-rotatably connected worm, which in turn meshes with a worm wheel which drives the actuator or linear actuator.
  • a non-rotatably connected worm which in turn meshes with a worm wheel which drives the actuator or linear actuator.
  • the actuator or linear actuator is generally composed of a spindle and a spindle element. By rotating the spindle can be achieved that the spindle element located thereon is moved back and forth in the linear direction depending on the direction of rotation. This linear movement of the spindle element is now used for the closing / opening movement, as will be explained in more detail in the context of the description of the figures.
  • a motor vehicle door lock which is equipped with a closing / opening device, which not only allows comfortable operation of an associated motor vehicle door, but is also characterized by a particularly quiet operation.
  • the closing / opening device is equipped with an intermediate attenuator of preferably an elastomeric plastic.
  • Fig. 2 is a motor vehicle door lock shown in the installed position, which is equipped as usual with a locking mechanism 1, 2 of rotary latch 1 and associated pawl 2.
  • the locking mechanism 1, 2 is associated with a closing / opening device 3 to 7, which in the present case is configured as a closing aid 3 to 7 and operates on the locking mechanism 1, 2 in a pulling-in sense.
  • the closing / opening device or closing aid 3 to 7 has a drive 3, 4, 5, which in the embodiment is designed as a linear drive 3, 4, 5.
  • the linear drive 3, 4, 5 is composed essentially of a motor 3a with output shaft 3b and a linear actuator 4, 5 acted upon by this.
  • the linear drive 3, 4, 5 between the motor 3a and the linear actuator 4, 5 additionally an intermediate gear 3c, 3d, which is configured in the embodiment as a worm gear 3c, 3d.
  • the motor 3a including the output shaft 3b and the gear 3c, 3d form taken together a motor drive 3, which acts on the linear actuator 4, 5 rotating.
  • the linear actuator 4, 5 is in turn composed of a spindle 5 and a linearly reciprocating on the spindle 5 spindle element 4.
  • the spindle 5 is a threaded spindle 5
  • the spindle element 4 is designed as a spindle nut 4.
  • the linear drive 3, 4, 5 works indirectly or directly on a closing / opening element 7, which is designed as a closing pawl 7 in the embodiment, which engages in a contour 8 of the locking mechanism 1, 2.
  • the contour 8 is formed on the outside of the rotary latch 1, so that the closing pawl 7 interacts with the contour 8 in question on the rotary latch 1.
  • the closing / opening device or closing aid 3 to 7 consists of the linear drive 3, 4, 5, the lever 6 and finally the closing pawl 7 together.
  • the linear drive 3, 4, 5 summarizes in turn the motor drive 3 and the linear actuator 4, 5 together.
  • the lever 6 has two lever parts 6a, 6b.
  • a lever part 6a is formed as a spindle lever part 6a and pivotally connected to the spindle element or the spindle nut 4.
  • the other lever part 6b is designed as a pawl lever part 6b and on the one hand mounted coaxially to the rotary latch 1 and on the other hand pivotally connected to the closing / opening element respectively the closing pawl 7 in the example.
  • the operation is as follows. To the catch 1 of the in Fig. 2 shown so-called pre-locking position to be translated into a pre-detent 12 ratchet pawl 2 in the main detent position, in which the pawl 2 is incident in a main catch 13 on the catch 1, it is necessary that engaging in the contour 8 of the catch 1 closing pawl 7, the catch 1 in the example turned counterclockwise, as a movement arrow in the Fig. 2 suggests.
  • This is achieved by the invention in that the spindle element or the spindle nut 4 in the illustration according to Fig. 2 is moved to the left.
  • the motor or electric motor 3a must put the spindle or threaded spindle 5 in the corresponding rotation.
  • the output shaft 3b of the motor 3a has a worm 3c meshing with a worm wheel 3d of the worm gear 3c, 3d.
  • the worm wheel 3d is arranged coaxially to the spindle 5 and rotatably connected thereto.
  • the closing pawl 7 Since the closing pawl 7 is connected at this other end or in a common pivot point 15 articulated to the pawl lever part 6b, also performs the Zuziehklinke 7 the desired counterclockwise movement, which follows the catch 1, because the Zuziehklinke 7 in the contour 8 on the catch 1 intervenes.
  • the linear actuator 4, 5 and the motor 3a are arranged at an angle to each other, wherein in the embodiment, both the motor 3a and the linear actuator 4, 5 are connected to the lock case 14 and connected thereto. It is also possible in principle to place the linear drive 3, 4, 5 in total separately from the lock case 14 and to this extent define a separate module for this purpose.
  • the connection between the linear drive 3, 4, 5 and the ratchet 1, 2 or at this point unaltered realized lever 6 may ensure a transmission element in this case, which is advantageously a Bowden cable or the like. This Bowden may like to attack instead of the spindle nut 4 to the spindle lever part 6a. This is not shown. Likewise not shown is the fundamental possibility, with the help of the motor 3a not the spindle 5, but rather to drive the spindle element 4.
  • the closing / opening device 3 to 7 corresponding to Fig.1 and 2 has according to the invention in each case via an intermediate attenuator respectively a clutch 16.
  • Die 3 and 4 Now show various embodiments of this attenuator or the clutch 16. All variants have in common that the attenuator 16 is made predominantly of an elastomer or an elastomeric plastic. In this case, the attenuator 16 is usually designed so that primarily from the engine respectively electric motor 3a resonances are attenuated, as has already been described in the introduction.
  • the attenuator 16 ensures that rotational movements of the motor 3a to the downstream actuator 4, 5 and linear actuator 4, 5 are transmitted. This can be done directly according to the variant Fig. 3 done by the attenuator 16 is integrated into a drive train of the motor 3a. Alternatively, however, an indirect transmission of the rotational movements is conceivable, as in the Fig. 4 will be shown. In this case, the attenuator 16 connects two locally separate components of the output train of the motor 3a.
  • this dog clutch 16a, 16b has at least two coupling elements 16a, 16b, which mutually engage with each axially upstanding jaws and corresponding receptacles. At least one of the two coupling elements 16a, 16b is made of said elastomer.
  • the output shaft 3b of the motor 3a is divided into two, with the one coupling element 16a connected to one end and the other coupling element 16b to the other end. Both ends are arranged coaxially with each other. As already described, ensures the unchanged realized worm gear 3c, 3d ensure that the (damped) rotational movements of the motor 3a are transmitted to the actuator or linear actuator 4, 5.
  • the attenuator 16 is formed as a drive belt 16.
  • the output shaft 3b of the motor 3a is again formed in two parts, each end pulley 17 of the locally separated parts by the drive belt 16 and the attenuator 16 are interconnected.
  • the rotational movements of the motor 3a (damping) on the worm 3c and finally the worm wheel 3d and subsequently the actuator 4, 5 are transmitted again.
  • the motor 3a and the actuator 4, 5 at an angle, according to the embodiment of the Fig. 1 to 4 arranged at right angles to each other, which requires a particularly compact design variant.
  • the attenuator 16 allows the addressed angle to be changed easily if necessary.
  • the lever 6, the spindle element 4 and optionally the closing / opening element 7 can be made entirely or partially in one piece.
