Definitions

  • the invention relates to a locking device for motor vehicles with a door lock in each motor vehicle door and with a central locking device which comprises an electrical control and an electrical drive device, wherein each door lock further comprises a housing, a fork latch with a pre-locking lug and a main locking lug, a detent and a central control element comprises, which is connected via lever and linkage to an outer door handle, an inner door handle, an inner locking button and optionally a locking cylinder.
  • Locking devices of the type mentioned have basically been known for a long time and also largely meet the requirements placed on them. Difficulties and problems arise citric acid, citric acid, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, tartrate, a tyl, but because the door seals closing oppose a high resistance. As a result, it is necessary to slam the motor vehicle door with great force, which in turn is associated with considerable impact noises.
  • the invention has for its object to provide measures by means of which it is possible to largely avoid the impact noises when the motor vehicle door is closed.
  • the desired solution should also be structurally simple and involve little additional effort.
  • This object on which the invention is based is achieved in that a closing device is provided which pivots the fork latch from the preliminary latching position into the main latching position and that the drive device of the central locking device serves as the drive for the closing device.
  • closing device By using a closing device, it is no longer necessary to bring the locking device into the main latching position by slamming the motor vehicle door firmly. It is sufficient if the motor vehicle door is closed to such an extent that the fork latch pivots from the open position into the pre-locking position. The actual closing process until the main catch position is reached is then taken care of by the closing device, which becomes effective when the fork catch is reached due to the position of the fork latch.
  • the closing device works electrically and is therefore particularly quiet.
  • the effort associated with the closing device is relatively low because the drive device of the central locking device also serves as a drive for the closing device.
  • the electric drive device has only one direction of rotation according to the invention.
  • a locking device 1 for motor vehicles comprises a door lock 2 for each motor vehicle door 3, which has an outer door handle 4, an inner door handle 5, an inner locking button 6 and optionally a locking cylinder 7, these parts being connected to the door lock 2 via levers and linkages.
  • the door lock 2 also includes a housing 8 with fastening openings 9 and a cover plate 10 (FIG. 2), under which there is a fork latch 11 (FIG. 6) which has a pre-locking lug 12 and a main locking lug 13.
  • the fork latch 11 is pivotally mounted on an axle 14 fixed to the housing and is held in its detent positions by a catch 15.
  • the catch 15 has a cam 15a, and it is also pivotable about an axis 16 which is also fixed to the housing. Both the fork latch 11 and the catch 15 are spring-loaded.
  • a drive device 20 with the electric motor 19 further includes a worm gear 21, a reduction gear 22 and a central unit 23 to which a drive shaft 24 leads from the reduction gear 22 (FIG. 2).
  • the central unit 23 has a drive disk 25 which is freely rotatable on the drive shaft 24 and is driven via a clutch 73 described later and which carries a drive pin with a roller 26.
  • the electric motor 19 When the electric motor 19 is actuated by the switch 18, it rotates the drive plate 25 through 360 ° , the roller 26 running on a fork latch nose 27 and pivoting the fork latch 11 such that its main latching nose 13 comes into engagement with the catch 15.
  • the electric motor 19 has thus pulled the fork latch 11 from the pre-latching position according to FIG. 6 into the main latching position according to FIG. 8, all the parts required for this closing process, namely the control surface 17 on the fork latch 11 and the electric switch 18, the clutch 73, which Drive plate 25 and its roller 26 and the fork latch nose 27 together represent a closing device.
  • the fork latch 11 carries a lever control cam 49 which changes from the position shown in FIG. 6 to the position shown in FIG. 8 moves when the fork latch 11 pivots from the pre-locking position into the main locking position when the motor vehicle door 3 is closed.
  • a deflection lever 50 is pivoted about its axis 52 fixed to the housing in order to bring a transmission lever 36 into its operative position.
  • the central locking takes place by actuation from the lock cylinder 7, ie using the key.
  • the locking cylinder 7 controls a switch 28 which immediately closes the circuit for the electric motor 19 when the locking cylinder 7 is rotated, so that it now continues in the same direction of rotation as in the closing process.
  • a cam disk 29, which also belongs to the central unit 23, is not rotated by the drive shaft 24 again by 360 ° , but only by 140 ° .
  • the cam disk 29 carries two cams 30 and 31 which are offset radially and axially from one another and are at an angle to one another on the circumference, as can be seen from FIGS. 4 and 5.
  • the other end 37 of the transmission lever 36 is articulated to a locking lever 38 via a bolt 101, which can be pivoted about an axis 39 fixed to the housing and has two arms 40, 41 and a third arm 42 in the shape of a fork.
  • the transmission lever 36 has an L-shaped elongated hole at its end 37 and is pivotably and displaceably articulated on the arm 40 of the securing lever 38.
  • the locking lever 38 is also pivoted about the housing-fixed axis 39 when the rocking lever 32 is pivoted, with the result that its arm 40 pivots a lifting lever 44 about an axis 45 perpendicular to the axis 39.
  • the axis 45 of the lifting lever 44 is not fixed to the housing, but rather sits on a release lever 46 which is pivotably mounted on the housing by means of an axis 47.
  • the lifting lever 44 is a central control element and serves to pivot the catch 15 (FIG. 6). However, this is only possible if the lifting lever 44 rests on the catch 15. If it itself is pivoted away from the catch 15 (FIG. 8, solid line), it is not possible to adjust the catch 15 to open the door lock 2 because it moves into the position shown in dash-dot lines when pivoted.
  • the lifting lever 44 is pivoted away from the catch 15 with the aid of the securing lever 38 and in this case is moved away from the active surface 102 on the cam 15a of the catch 15 with its lifting surface 48 which serves to lift the catch 15.
  • the door lock 2 is thus locked or the vehicle is centrally locked, since corresponding control pulses from the switch 28 of the locking cylinder 7 are also given to the electric motors 19 of the door locks 2 in the other motor vehicle doors.
  • the lever control cam 49 on the fork latch 11 which cooperates with a deflection lever 50 when the fork latch 11 is pulled from the pre-latched position into the main latching position.
  • the deflection lever 50 engages the transmission lever 36 in the region of a further elongated hole 51 and pivots the transmission lever 36 about its axis of rotation or the bolt 35 on which the pivot levers 32, 53 are articulated, so that a positive engagement with the locking lever 38 in an L-shape Slot 43 is achieved.
  • the deflection lever 50 can be pivoted about an axis 52 fixed to the housing and is pressed against the fork latch 11 by a spring or tension spring 103.
  • a current pulse is given to the electric motor 19 via the switch 28, so that the drive shaft 24 and thus the cam disk 29 continue to rotate through 220 ° to the starting position.
  • the second cam 31 pivots the second rocker arm 53, which is mounted on an axle 54 fixed to the housing. Since the rocker arm 53 is connected to the transmission lever 36 via the bolt 35, it also shifts it in the longitudinal direction thereof, in the opposite direction to the direction of movement achieved with the other rocker arm 32, which at the same time swings back into its starting position according to FIG. 4.
  • the transmission lever 36 is therefore moved in the opening direction, so that he the locking lever 38 to the ge axis 39 fixed to the housing, whereby the lifting lever 44 is pivoted back into the position in which its lifting surface 48 with the active surface 102 on the cam 15a of the detent 15 can be brought into the active position by actuating the trigger lever 46.
  • Outside door handle 4 and inside door handle 5 are indirectly connected with the lifting lever 44 with the interposition of further levers and the linkage parts 104, 62, so that when pulling on the outside door handle 4 or on the inside door handle 5 of the lifting lever 44 the catch 15 is pivoted, as a result of which the fork latch 11 is released.
  • the motor vehicle door 3 thus swings open.
  • the lifting lever 44 is the central and decisive control element because it can either pivot the catch 15 or not at all with it Active connection arrives.
  • the lock cylinder 7 also pivots a shift nut 56 via an extension 55 (FIGS. 3 and 4).
  • the approach 55 sits in the nut 56 with rotation. This ensures that when the locking cylinder 7 is switched, the switch 28 first switches on the electric motor 19 before the driver 58 engaging in an elongated hole 57 in the arm 41 of the locking lever 38 can pivot the locking lever 38. In the event of a power failure, the safety catch 38 can therefore also be moved in the opening or closing direction with the aid of the locking cylinder 7.
  • the outer door handle 4 is connected to the lifting lever 44 via an intermediate lever 59 and the release lever 46.
  • the axis 60 carrying the intermediate lever 59 is fixed to the housing.
  • the rod 62 is connected to a further linkage 64.
  • the rod 62 and the linkage 64 can be moved in the direction of the arrows A in FIG. 3 when the outer door handle 4 is opened and closed, the intermediate lever 59 pivoting about its axis 60 and at the same time also moving the release lever 46.
  • the release lever 46 carries the axis 45 for the lifting lever 44, and by pivoting this axis 45 the lifting lever 44 is moved relative to the detent 15 such that it pivots in the opening direction.
  • the intermediate lever 59 also engages with an arm 65 on a roller 66 which projects laterally from the release lever 46 (FIG. 5).
  • the inside door handle 5 or a linkage belonging to it engages on a multi-part pivot lever 67 which engages directly with the arm 68 in the release lever 46, as can be seen above all from FIG. 4.
  • the intermediate lever 59 finally has at its end 69 (FIG. 5), which cooperates with the roller 66 on the release lever 46, a control surface 70 which is selected such that the static friction tip between the fork latch 11 and catch 15 when opened by continuously changing the travel angle - Ratio is reduced.
  • the door lock 2 also has an emergency release device 71 (Fig. 12-13) because e.g. the power can fail.
  • This emergency release device 71 comprises a clutch 73 between the drive shaft 24 and the drive plate 25, which carries the roller 26.
  • the drive plate 25 is freely rotatable on the drive shaft 24 and is taken along when the drive shaft 24 rotates counterclockwise in FIGS. 5 and 6, because a coupling element in the form of a drive lever 73 engages in a recess 74 on the circumference of the drive plate 25 .
  • the driving lever 73 is pivotable about an axis 75 and acted on by a spring 76 on the cam disk 29, so that it is always pressed radially inwards and rests on the circumference or in the recess 74 of the driving disk 25 with a bolt-like projection 77.
  • This emergency release lever 79 is pivotally mounted with its one end 80 on a bolt 81 in the housing 8 and surrounds the drive plate 25 or the cam plate 29 in a semicircular shape, as can be seen from FIGS. 12 and 14.
  • the emergency release lever 79 has a semicircular curve 82 or guide 82 which consists of a semicircular rib.
  • the mandrel 78 on the driving lever 73 engages behind the curve or guide 82 (FIG. 12), i.e. the mandrel 78 runs along the outside of the curve or guide 82 with each rotation of the drive shaft 24.
  • the emergency release lever 79 is pivoted away from the drive shaft 24 about the bolt 81, it lifts the projection 77 on the driving lever 73 out of the recess 74 in the driving plate 25, as shown in FIG. 14.
  • An articulated angle lever 83 is used to pivot the emergency release lever 79 around the bolt 81, which can be pivoted about a bolt 84 in a manner fixed to the housing and is articulated with its second arm 85 on the release lever 46, as best shown in FIG.
  • levers and linkages are spring-loaded for the proper execution of all functions, insofar as this is necessary or as is shown essentially in the figures.
  • the running surface of the fork latch nose 27 is curved in order to avoid a sudden separation of the running surfaces of the roller 26 and the fork latch nose 27 under load at the time of the overpressure when closing.
  • the curve is preferably slightly S-shaped. The main notch 13 thus slowly engages the notch 15.
