Definitions

  • the present invention relates to a locking mechanism for a motor vehicle door according to the preamble of claim 1.
  • motor vehicle door is to be interpreted comprehensively and also includes motor vehicle flaps, covers, sliding doors, hoods and all closure elements that cover openings in a vehicle.
  • a locking mechanism shown that includes a rotary latch, which is loaded by a spring in the opening direction.
  • This catch is positively locked in the closed state by a pawl.
  • the pawl is pivotally mounted on a pawl lever and loaded by a spring in the blocking direction to the catch.
  • the pawl lever is loaded by another spring in the opening direction.
  • the opening of the lock is prevented by the positive connection to a locking lever.
  • the locking lever is loaded by a further spring in the closing direction.
  • This locking lever can be brought out of engagement with the pawl lever by means of a solenoid, so that the pawl lever with the pawl pivots out of the engagement region of the rotary latch and opens it.
  • the striker not shown, rotates the catch in the closing direction. Only the pawl is moved without pawl lever in the opening direction and closed immediately by the pawl spring.
  • the pawl and the rotary latch are arranged to each other such that the rotary latch on the pawl generates a torque in the opening direction.
  • This is indicated by the force parallelogram in Fig. 2 of the US 3,386,761 shown in detail.
  • this arrangement has the disadvantage that the pawl can move in the opening direction with strong vibration forces. By the movement of the pawl in the opening direction of the blocking of the catch is released, so that the lock and thus the vehicle door can open.
  • the invention has for its object to provide a barrier, which has a low noise when closing, but also in vibration and other mechanical influences keep the door securely in closed position.
  • the barrier invention is characterized by the features specified in claim 1. Details of the invention will become apparent from the dependent claims.
  • the blocking mechanism according to the invention consists i.a. from a catch and a pawl mechanism, which are usually part of a motor vehicle lock.
  • motor vehicle locks hold in conjunction with a striker vehicle doors, trunk lid, trunk, hoods, trunk lid or sliding doors in the closed position, or can be opened by means of the locks.
  • motor vehicle door stands for all elements that cover openings in vehicles.
  • the locks with the locking mechanisms are usually mounted in the doors, with the corresponding firing bracket to the body, preferably on the B or C-pillar is attached.
  • the lock with the locking mechanism is attached to the body, wherein the striker on the moving part, the trunk lid is complained.
  • the positioning of the components thus has no influence on the invention.
  • all elements are designated, e.g. also locking bolts or strikers, which form a positive connection with the locking mechanism.
  • the locking mechanism consists of a rotary latch and a pawl mechanism.
  • the catch is in closed door with the striker in positive connection. When opening the door, this positive connection is released.
  • the rotary latch is preferably a U-shaped element which is pivotally mounted.
  • a spring loads the catch in the opening direction.
  • the striker presses on one leg of the U-shaped rotary latch, whereby the other leg of the rotary latch rotates about the striker and thus forms a positive connection with the striker.
  • This position of the catch is fixed with the door closed by a pawl. Both the pawl spring and the door seal exert pressure on the pawl via the striker and the catch.
  • this loading direction is referred to as "in the closing direction”.
  • the opening direction the direction of movement is referred to, in which the rotary latch pushes the pawl, or the pawl assembly in the direction in which the pawl is disengaged from the catch.
  • the essence of the invention is now to arrange the contact surfaces between the catch, pawl and pawl lever, and their pivot points such that the force of the catch acting on the pawl, generates a torque which enhances the blocking between pawl and rotary latch. At the same time generates the same force of the rotary latch, a torque on the assembly of pawl lever and pawl, through which the assembly of pawl lever and pawl is loaded in the opening direction.
  • the force transmitted by the catch to the pawl is generated by a rotary latch spring and the door seal.
  • the rotary latch spring engages directly on the rotary latch and generates a torque that loads the rotary latch in the opening direction.
  • a much higher force is generated by the door seal when the door is closed.
  • the door seal which is arranged between the body and the door, generates a force on the door structure, also referred to as a door frame, on the lock, in particular on the locking mechanism, in particular on the catch.
  • the rotary latch is in positive connection with the striker, whereby the power flow is closed.
  • the force thus generated is transmitted from the catch to the pawl or to the assembly of pawl lever and pawl.
  • Both pawl and pawl lever are loaded by a spring in the direction of the catch.
  • the pawl is shaped so that it is mounted on the pawl lever and welißt a contour which is in positive connection with a contour of the pawl lever.
  • the spring force of the rotary latch spring is now transmitted to this contour of the pawl and directly on the pawl lever contour on the pawl lever, which is thereby loaded in the direction of the rotary latch.
  • Both rotary latch and pawl and pawl lever are designed such that the rotary latch on the assembly of pawl lever and pawl generates a torque that loads the assembly in the opening direction.
  • the movement of the pawl pawl lever assembly in the opening direction is prevented by the locking lever. This is done by the locking lever blocking the pawl lever in the opening direction.
  • the locking lever is pivoted out of the path of the pawl lever, whereby the positive engagement is released and the pawl-pawl lever assembly moves in the opening direction.
  • the locking lever is loaded by a spring in the direction in which it blocks the pawl lever. By a motor drive or manually, the locking lever can be disengaged from the pawl lever.
  • the opening operation described above is always associated with the fact that the engagement between the pawl and the catch is canceled. This can be done in a pulse-like manner in a preferred variant by the pawl is pulled out of the range of motion of the rotary latch. This type of lifting the pawl is always associated with a corresponding pulse-like noise.
  • the opening operation is accompanied by a rolling movement of the pawl on the rotary latch. Further preferably, the pawl rotates in the course of the rolling movement of the main catch or pre-catch the catch out. The rolling movement described above ensures that a pulse-like noise by canceling the engagement between pawl and rotary latch does not occur.
  • a motor vehicle door lock is claimed with a barrier.
  • the proposed motor vehicle door lock can be positioned in a motor vehicle door or in a door frame.
  • the motor vehicle door lock keeps the motor vehicle door closed in conjunction with a striker positioned on the door frame or door or opens the motor vehicle door accordingly, with a detent having a catch positively connected to the striker when the motor vehicle door is closed, with a detent pawl holding the catch closed motor vehicle door, in a pre-locking position or a main detent position, blocked and with an assembly consisting of a pivotable intermediate lever and the pivotally mounted therein pawl which blocks the catch when the vehicle door is closed, in a pre-locked position or a main detent position.
  • Fig. 1 shows an inventive locking mechanism in the open position.
  • the firing bow 2 is not in engagement with the rotary latch 1.
  • the pawl 3 is mounted on the pawl mandrel 7, wherein the pawl mandrel 7 is positioned on the pawl lever 4.
  • the pawl lever 4 is pivotally mounted on a mandrel 8.
  • the force of the pawl spring 5 engages the lever arm 9 of the pawl 3 and is transmitted to the lever arm 10 of the pawl lever 4. This causes a movement of the pawl lever 4 in a clockwise direction.
  • the movement of the pawl lever 4 is stopped via the Blockadehebelarm 11 which abuts against the contour 12 of the locking lever 6.
  • a locking lever spring 13 loads the locking lever 6 in the closing direction.
  • the striker 2 moves, as in Fig. 2
  • the striker 2 presses on the contour 15 of the catch 1, whereby the catch 1 moves to the Dreh fallendom 16 in the closing direction.
  • the contour 18 of the rotary latch pivots the pawl 3 on the contour 17 in the counterclockwise direction in the opening direction.
  • This is done against the force of the pawl spring 5 is particularly clear in Fig. 2 in that, during the closing operation, only the pawl 3 pivots about the pawl mandrel 7, the pawl lever 4 remaining in its position.
  • the pawl 3 falls due to the spring force of the spring 5 back to its original position (see Fig. 3 ). Due to the low mass of the pawl 3 is formed when hitting the pawl lever 4 only a slight noise.
  • Fig. 3 the locking mechanism is shown in closed position.
  • the rotary latch 1 presses on the pressure contour 23 on the locking contour 19 of the pawl third
  • the point of attack on the pawl contour 19, on which the pressure contour 23 of the catch 1 engages and the pivot point 7 is mounted on the pawl 1 are arranged to each other that the lever arm 9 of the pawl 3, the lever arm 10 of the pawl lever 4 charged.
  • the locking lever 6 blocked with the contour 12 via the blocking arm 11, the pawl lever 4. Due to this assignment blocks the pawl 3 in conjunction with the pawl lever 4 and the locking lever 6, the movement of the catch 1 in the open position.
  • Fig. 4 is the rotary latch 1, the pawl 3, the pawl lever 4 and the locking lever 6 is shown enlarged.
  • the direction of the force exerted by the rotary latch 1 on the pawl 3 is shown in this view by the arrow 20.
  • the force direction 20 extends between the pivot point 7 of the pawl 3 and the pivot point 8 of the pawl lever 4. This causes the pawl 3, a clockwise torque is generated. Even with vibrations, the pawl 3 always tries to move in the clockwise direction. However, this movement of the pawl 3 is positively locked by the lever arm 10 of the pawl lever 4 and the lever arm 9 of the pawl 3. Thus, a torque in the closing direction is generated on the pawl 3 in the closed position. On the other hand, if a torque is generated counterclockwise, the pawl can escape against the spring force of the pawl spring 5. In this case, a torque is generated in the opening direction.
  • the Fig. 6 to 10 show a barrier according to the invention in a further embodiment.
