Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism of the catch and pawl, wherein the pawl rests in the closed state of the locking mechanism with its locking contour on a latching contour of the rotary latch.
  • the locking mechanism of a motor vehicle door closure is a core component of the closure, because ultimately the locking mechanism ensures that an associated motor vehicle door is locked and held in relation to the motor vehicle body.
  • the catch of rotary latch and pawl is solid and usually made of steel to accommodate occurring at this point considerable forces can.
  • a motor vehicle door lock with the locking mechanism therein is mounted inside a motor vehicle side door and typically interacts with a locking bolt on the vehicle body, such as a B-pillar.
  • the catch can be locked in a pre-rest and in a main position by means of a pawl.
  • the pawl has not only a locking member, but also a safety locking member.
  • a device for closing and closing and for opening a rear door on a motor vehicle body is described.
  • a Zuziehschwinge is mounted on a lock plate coaxially to the catch.
  • the pawl is arranged eccentrically to the catch on the Zuziehschwinge and can be lifted in this way with the help of Zuziehschwinge of the rotary latch motor.
  • a mechanical coupling of the closing function and the pawl operation is realized in the known teaching.
  • the catch and the pawl are massively designed for the reasons already described above, it comes when lifting the pawl of the catch often undesirable and annoying perceived "click" noises. These are often supported and reinforced by the fact that the tailgate closes a Heckraumvolumen, which acts insofar as resonant volume or can act.
  • the invention aims to provide a total remedy.
  • the invention is based on the technical problem of developing a motor vehicle door lock of the design described above so that the noise behavior of the locking is improved overall, with the emphasis is on any noise when Lift off the pawl of the catch as possible minimize.
  • the motor vehicle door lock has, in the context of the invention, a locking mechanism of a catch and a pawl, wherein the pawl rests in the closed state of the locking mechanism with its locking contour on a latching contour of the rotary latch.
  • the locking contour is formed in two parts with retaining contour and rolling contour, wherein the retaining contour interacts predominantly in the closed state of the locking mechanism with the locking contour, whereas the rolling contour beyond the opening process of the rotary latch on the locking contour and optionally additionally rolls on a leg of the rotary latch, so that the opening catch is lifted virtually noiselessly from the rolling edge of the pawl.
  • the rolling contour and the retaining contour are each formed as circular arcs. It works regularly with different radii and / or different centers for on the one hand the rolling contour and on the other hand, the holding contour. According to the invention, the radius of the rolling contour exceeds the radius of the retaining contour so that the rolling contour can correspond to the function of the "caster” described below in relation to the opening movement of the rotary latch.
  • the pawl is thus equipped with a special locking contour.
  • the locking contour is composed essentially of the retaining contour and the rolling contour, which are designed differently from each other.
  • the holding contour in the closed state of the locking mechanism ensures that the pawl does its original function by the holding contour interacts with the locking contour of the rotary latch.
  • the catch contour of the catch can have a total of a preliminary catch and a main catch or be formed as a pre-locking or main catch contour, wherein the catch is supported in the associated locking positions respectively on the holding contour of the pawl.
  • the pawl according to the invention still has a rolling contour, wherein the holding contour and the rolling contour as a whole define the locking contour.
  • the rolling contour generally has no supporting or locking effect. Rather, the rolling contour of the pawl only comes into action when the catch has already started its opening process, ie has left the closed position or the closed state. In this case, the holding contour on the pawl and the locking contour on the catch are not or mostly no longer engaged.
  • the rolling contour now ensures in this opening operation of the rotary latch - starting from the closed state of the locking mechanism - that the locking contour and possibly additionally a leg of the rotary latch can roll on the rolling contour. It thus takes place according to the invention and deliberately over the actual closed position and the associated supporting effect of the retaining contour relative to the locking contour beyond mechanical contact of the rotary latch with the pawl instead.
  • the rolling contour on the pawl and, on the other hand, the rollover of the locking contour or the additional leg on the catch are responsible.
  • the retaining contour and the rolling contour generally adjoin one another at the end of the locking latch on the side of the rotary latch. It is usually the procedure that the holding contour is connected to the rolling contour in Aushebecardi the pawl.
  • the Aushebecardi the pawl usually corresponds to a pivoting movement about an associated axis of rotation. This pivoting movement of the pawl can be initiated mechanically and manually with a lever.
  • the pawl is usually assigned a drive unit to its motorized lifting, that is, the drive unit ensures that the pawl is dug and also provides the Ausheberaum the pawl.
  • the pawl performs a total of the already mentioned pivotal movement about the axis of rotation. Opposite the axis of rotation or the rotation axis side end of the pawl is the rotary latch side end of the pawl with the there provided retaining contour and the rolling contour.
  • the design is usually made so that the rolling contour in Aushebecardi the pawl, the retaining contour at least partially surmounted radially.
  • the rolling contour projects beyond the retaining contour in the relevant Aushebecardi the pawl generally progressively or progressively radially. That is, with increasing pivot angle of the pawl about its axis of rotation and the radial distance between the holding contour and the rolling contour is larger, increases progressively.
  • the invention takes into account the fact that the opening catch and the pivoted pawl in the lifting direction increasingly remove from each other at their contact area.
  • the invention now provides at this point a compensation in that the rolling contour projects beyond the retaining contour progressively radially.
  • the design is such that the rolling contour in Aushebecardi the pawl with the catch in its closed state overlaps at least partially. Most of the rolling contour overlaps in the respective Ausheberaum with the locking contour on the catch and possibly the leg of the catch in its closed state. This overlap takes into account the fact that when you open the catch the pawl and the catch generally remove from each other. In order to ensure at this point according to the invention a beyond the closed state mechanical contact can, the pawl of the catch rushes as it were. That gets in the core achieved in that the rolling contour in the Aushebecardi the pawl overlaps with the rotary latch or with the locking contour and possibly the leg of the rotary latch on which or on which the pawl slides in the described opening movement with the rolling contour.
  • the center of the rolling contour and the center of the retaining contour are usually spaced apart. It is generally provided that the center of the retaining contour is arranged below the axis of rotation of the pawl and the center of the rolling contour above the axis of rotation. In addition, the respective center points and the axis of rotation are preferably located on a common connection path.
  • a motor vehicle door lock is provided with a locking ratchet pawl and rotary latch, which can be opened particularly particularly quiet.
  • the low noise is achieved in that the pawl and the rotary latch - starting from the closed state of the locking mechanism - have a more extensive mechanical contact. This mechanical contact is made on the one hand by the rolling contour of the pawl and on the other hand, the locking contour of the catch and possibly also a leg of the catch.
  • the design is such that the contiguous contours of one hand the pawl and the other hand, the catch slowly and not abruptly change, so that a total of a particularly "soft" transition from the closed state of the locking mechanism on the subsequent opening movement observed with unchanged mechanical contact between pawl and rotary latch until finally the separation between the catch and pawl becomes. This movement is associated with special acoustic benefits.
  • a motor vehicle door lock which has a lock case 1, in which a locking mechanism 2, 3 of rotary latch 2 and pawl 3 is mounted.
  • a locking mechanism 2, 3 of rotary latch 2 and pawl 3 is mounted to the rotary latch 2.
  • the pawl 3 is pivotally mounted about an axis of rotation 5.
  • the locking mechanism 2, 3 is in the Fig. 1 shown in closed condition. To open the locking mechanism 2, 3 operates in the embodiment and not limiting a drive unit 7, 8 on the pawl 3.
  • the drive unit 7, 8 is composed in the example of a motor or electric motor 7 and an acted upon by the motor 7 actuating cam 8 together ,
  • the actuating cam 8 is designed as a whole spiral, so that a rotation about an associated axis 9 by means of the electric motor 7 causes the pawl 3 is lifted from the catch 2.
  • the rotary latch 2 is supported in the illustrated closed state of the locking mechanism 2, 3 with a latching contour 10 on a locking contour 11, 12 of the pawl 3 from.
  • the latching contour 10 is a main latching contour 10 of the rotary latch 2.
  • a latching contour 13 is still provided on the rotary latch 2, which, however, is unimportant for the following considerations.
  • the locking contour 11, 12 of the pawl 3 is inventively formed in two parts and consists of a retaining contour 11 and a rolling contour 12th together.
  • the retaining contour 11 interacts predominantly in the closed state of the locking mechanism 2, 3 with the locking contour or main locking contour 10 of the rotary latch 2.
  • the rotary latch 2 is supported in the closed state of the locking mechanism 2, 3 at precisely this retaining contour 11 of the locking pawl 3 (see , Fig. 2 ).
  • the retaining contour 11 and the rolling contour 12 are first arranged once at a rotary latch end of the pawl 3 and close to each other.
  • This rotary latch-side end of the pawl 3 is the axis of rotation-side end of the pawl 3 opposite, on which the axis of rotation 5 of the pawl 3 is found.
  • the retaining contour 11 is connected to the rolling contour 12 in the lifting direction A of the pawl 3. You can also see from the enlarged view in Fig. 2 in that the rolling contour 12 in the relevant lifting direction A of the pawl 3 projects beyond the holding contour 11 at least partially radially.
  • the rolling contour 12 overlaps in the Aushebecardi A of the pawl 3 with the catch 2 in the closed state at least partially. In fact, one observes at this point an overlap area 14, which in the Fig. 2 hatched.
  • the rolling contour 12 as well as the retaining contour 11 are each formed as circular arcs. Radii r 1 , r 2 and associated centers M 1 , M 2 correspond to the circular arcs.
  • the radius r 1 belongs to the retaining contour 11 and starts from the associated center M 1 of the retaining contour 11.
  • the radius r 2 corresponds to the rolling contour 12 and is struck around the associated center M 2 .
  • the overall design is such that the respective circular arcs or contours 11, 12 are equipped with different radii r 1 , r 2 and also different centers M 1 , M 2 respectively.
  • the radius r 2 of the rolling contour 12 exceeds the associated radius r 1 of the retaining contour 11.
  • the locking contour 11, 12 on the pawl 3 as a whole is designed and designed so that the locking contour 11, 12 when lifting the pawl 3 and consequently the opening movement of the rotary latch 2 of the associated locking contour 10 latches on the catch 2 as it were or runs after.
  • the circumstance contributes to the fact that the center M 1 of the retaining contour 11 or of the associated circular arc with the radius r 1 is arranged below the axis of rotation 5 of the pawl 3.
  • the two centers M 1 , M 2 and the axis of rotation 5 are arranged on a common joint, as a whole Fig. 2 dash-dotted lines indicate. This is, of course, as well as the arrangement of the centers M 1 , M 2 compared to the axis of rotation 5 by way of example only and not restrictive to understand.
  • the detent contour 10 of the catch 2 moves away from the retaining contour 11 of the pawl 3.
  • the rolling contour 12 of the pawl 3 connects to the retaining contour 11 and with the already described progressively increasing radial distance in comparison is designed for holding contour 11, the rolling contour 12 of the pawl 3 of the locking contour 10 on the catch 2 as it follows in this opening process.
