Definitions

  • the invention relates to a motor vehicle lock according to claim 1 and a method for assembling such a motor vehicle lock according to claim 13.
  • the motor vehicle lock in question can be assigned to all types of locking elements of a motor vehicle. These include doors, in particular side or rear doors, trunk lids, tailgates, bonnets, load compartment floors or the like.
  • the motor vehicle lock is equipped with bearing domes on each of which a plurality of axially spaced levers are mounted.
  • the resulting set of levers is often supported on housing components via spacer sleeves.
  • the invention is based on the problem of specifying a motor vehicle lock which allows a tolerance-insensitive mounting of, in particular, a plurality of levers on a geometrical lever axis with little manufacturing effort.
  • the proposed motor vehicle lock is equipped with a lock mechanism and with a lock housing to accommodate the lock mechanism.
  • the lock mechanism has at least one actuating lever pivotable about a geometric lever axis, a bearing sleeve element being provided on which the actuating lever is radially supported.
  • the actuating lever is not only mounted radially on the bearing sleeve element, but also mounted axially. It is essential that the actuating lever is coupled to the bearing sleeve element via a bayonet lock for axially bilateral mounting. It is also essential that, within the framework of the assembly of the motor vehicle lock, the actuating lever can be preassembled together with the bearing sleeve element to form a separate unit by producing the bayonet lock.
  • the design of the axial lock between the actuating lever and the bearing sleeve element as a bayonet lock is advantageous in that the bayonet lock can be generated with simple assembly movements, in particular in an automated manner, and that the bayonet lock ensures a secure, axially two-sided mounting of the actuating lever without great mechanical effort can be implemented.
  • the preferred configurations according to claims 2 to 5 relate to preferred variants for producing the bayonet lock.
  • the particularly preferred embodiment according to claim 5 offers the possibility of a simple pre-assembly of the actuating lever and bearing sleeve element in that no precise and therefore complex assembly movements are required during pre-assembly and with a suitable design.
  • in the installed state of the motor vehicle lock it is ensured solely by restricting the movement of the actuating lever and the bearing sleeve element that unlocking of the bayonet lock is blocked. A separate locking element for locking the bayonet lock is accordingly not required.
  • the bearing sleeve element is axially supported on two sides and can in this respect serve as a spacer.
  • the bearing sleeve element provides an axial support, that is, an axial bearing, for at least one additional lever. Because the bearing sleeve element, which is preferably mounted on the bearing dome, simultaneously provides an axial bearing for at least one additional lever, the build-up of undesired tolerance chains from one lever to the other lever can be reliably avoided.
  • the actuating lever and the bearing sleeve element form a pre-assembled unit with the formation of the bayonet lock, the pre-assembled unit then being otherwise mounted on the motor vehicle lock.
  • the pre-assembly of the actuating lever and the bearing sleeve element allow the parallelization of process steps, the proposed construction of the bearing sleeve element ensuring compliance with predetermined tolerances.
  • the motor vehicle lock 1 shown in the drawing is assigned to a side door 1a of a motor vehicle.
  • the motor vehicle lock 1 can in principle be used on all types of locking elements of a motor vehicle. In this respect, reference may be made to the introductory part of the description.
  • the basic structure of the motor vehicle lock 1 comprises the locking elements lock latch 2 and pawl 3, which interact in a conventional manner.
  • the latch 2 can be brought into at least one closed position in which it is in holding engagement with a closing element 4, in particular a striker or a striker.
  • the latch 2 is held in its closed position by the pawl 3.
  • the excavation of the The pawl 3 is connected to the release of the latch 2 into its open position, which is associated with the release of the locking element 4.
  • the side door 1a receives the motor vehicle lock 1, while the locking element 4 is arranged on the motor vehicle body.
  • the reverse can also be provided.
  • Fig. 1 further shows that an outside door handle 5 and an inside door handle 6 are provided which are each coupled to the motor vehicle lock 1 via Bowden cables 5a, 6a. Depending on the closed state of the motor vehicle lock 1, the pawl 3 can be lifted out by actuating the outside door handle 5 or the inside door handle 6.
  • the illustrated motor vehicle lock 1 is equipped with a lock mechanism 7, which here includes all the mechanical components required to implement the lock functions.
  • the lock mechanism 7 is accommodated in a lock housing 8, which does not necessarily have to be designed to be closed.
  • the term "lock housing” is to be understood broadly. In principle, it can also be that a rear panel or a locking plate is part of the lock housing 8a in this sense.
  • the lock mechanism 7 has at least one actuating lever 11 that can be pivoted about a geometric lever axis 10.
  • the operating lever 11 is an external operating lever which is coupled to the outside door handle 5 via the Bowden cable 11a.
  • Fig. 2 shows that a bearing sleeve element 12 is provided on which the actuating lever 11 is mounted radially. This is best seen by looking at the Fig. 2 , 3 and 4th .
  • the actuating lever 11 is axially supported on two sides on the bearing sleeve element 12. This means that the axial adjustability of the actuating lever 11 in both axial directions is defined by the axially bilateral bearing.
  • the actuating lever 11 is coupled to the bearing sleeve element 12 via a bayonet catch 13. This in turn results from a synopsis of the Fig. 2 , 3 and 4th .
  • At least two actuation levers 11, preferably more than two actuation levers 11, can also be mounted on the bearing sleeve element 12.
  • bearing sleeve element 12 preferably more than two bearing sleeve elements 12, are provided, each of which supports at least one actuating lever 11.
  • a fixing arrangement (not shown) is preferably provided between the actuating lever 11 and the bearing sleeve element 12.
  • the fixing arrangement can be a latching arrangement which has to be locked in place when the bayonet catch 13 is produced. It is also conceivable that during the manufacture of the bayonet lock 13 crushing ribs have to be traversed, which ensure that the bayonet lock cannot be released without an increased expenditure of force.
  • a synopsis of the Fig. 3 and 4th shows that the bearing sleeve element 12 is designed to be non-rotatable with the lock housing 8 in relation to the lever axis 10.
  • the bearing sleeve element 12 has a support arm 15 which is supported against the lock housing 8 in a rotationally fixed manner with respect to the lever axis 10.
  • the support arm 15 has an opening 15a which is pushed onto a bearing dome 16 when the unit 14 is assembled. The fact that the bearing dome 16 is spaced from the lever axis 10 results in the desired support effect.
  • the bayonet lock 13 is formed by a bayonet recess 17 on the bearing sleeve element 12 on the one hand and by a bayonet counter-recess 18 on the actuating lever 11 on the other hand.
  • the components operating lever 11 and bearing sleeve element 12 can be derived from the in Fig. 2 Slide out the position shown axially into one another.
  • the bayonet lock 13 can be moved into the positions shown in FIG Fig. 3 Bring shown, locked state in which the bayonet recess 17 and the bayonet counter-recess 18 form an undercut.
  • Pivoting back leads to the bayonet catch 13 assuming its unlocked state. It is essential that only in the locked state ( Fig. 3 ) the axially bilateral bearing between the actuating lever and the bearing sleeve element 12 is provided. In the unlocked state ( Fig. 2 ) on the other hand, an axial adjustment of the actuating lever 11 and the bearing sleeve element 12 is possible.
  • the proposed solution enables a particularly secure axially two-sided mounting of the actuating lever 11 on the bearing sleeve element 12.
  • the actuating lever 11 and the bearing sleeve element 12 in the installed state of the motor vehicle lock 1 assume a locking pivot position with respect to one another with respect to the bayonet catch 13, so that the bayonet catch 13 is in its locked state as discussed above.
  • the arrangement is furthermore preferably such that the actuating lever 11 and the bearing sleeve element 12 in the installed state of the motor vehicle lock 1 are restricted in movement in such a way that unlocking of the bayonet catch 13 is blocked.
  • FIG. 4 The sectional view according to Fig. 4 shows that the bearing sleeve element 12 is axially supported on two sides. There is a support point on part of the lock housing 8, here on an in Fig. 4 only indicated housing cover 8a.
  • the bearing sleeve element 12 has an axial extension 19, on which the bayonet recess 17 is arranged here and preferably.
  • the axial extension 19 has a further function, namely the function of the axial support of the bearing sleeve element 12 on the lock housing 8, here on the housing cover 8a.
  • the axial extension 19 takes on a further function, namely the function of receiving a spring element 20, which in a particularly preferred embodiment is a helical spring element, in particular a leg spring element, for the actuating lever 11.
  • the spring element 20 is assigned to another component of the lock mechanism 7.
  • Fig. 4 shows that the bearing sleeve element 12 has the function of a spacer, by means of which the actuating lever 11 is held at a predetermined distance from the housing cover 8a.
  • the motor vehicle lock 1 has a further bearing dome 21, the bearing sleeve element 12, as in FIG Fig. 4 is arranged coaxially to the bearing dome 21.
  • the bearing sleeve element 12 is pushed onto the bearing dome 21.
  • the bearing sleeve element 12 can be inserted into the bearing dome 21 or attached to the bearing dome 21.
  • the bearing dome 21 is connected to a part of the lock housing 8, preferably with a housing trough 8b, here and preferably in one piece.
  • the bearing sleeve element 12 is supported on the housing cover 8a via its axial extension 19.
  • the bearing sleeve element 12 is supported axially at its end facing away from the housing cover 8a on the bearing dome 21, here and preferably on a radial shoulder 22 of the bearing dome 21.
  • This preferably results in the bearing sleeve element 12 being fixed, in particular clamped, between the housing cover 8a of the lock housing 8 and the bearing dome 21. Additional measures for fastening the bearing sleeve element 12, which can be, for example, an additional riveted connection or the like, are thus omitted.
  • the lock mechanism 7 preferably has at least one additional lever 23, 24, here and preferably two additional levers 23, 24, which can be pivoted about the geometric lever axis 10 and which is or are pivotable about the geometric lever axis 10.
  • the additional levers 23, 24 are supported here and preferably on the bearing dome 21.
  • the bearing points of the additional levers 23, 24 are axially spaced from the bearing point of the actuating lever 11.
  • the additional levers 23, 24, like the bearing sleeve element 12, are pushed onto the bearing dome 21.
  • the additional lever 23 is the internal operating lever which, when the motor vehicle lock 1 is installed, is coupled to the inside door handle 6 via the Bowden cable 6a.
  • the additional lever 24 is a so-called release lever which, depending on the state of the lock, can be actuated by the external actuating lever 11 and / or the internal actuating lever 23 and acts on the pawl 3.
  • the two additional levers 23, 24 are arranged between a further radial shoulder 25 of the bearing dome 21 and a circumferential collar 26 of the bearing sleeve element 12 and are thereby axially supported on two sides.
  • the axial mounting of the actuating lever 11 on the one hand and the additional levers 23, 24 on the other hand have no alternating, tolerance-related influence on one another.
  • the bearing sleeve element 12 has a further axial extension 27, which is designed as an internal operating lever with the Additional lever 23 is in engagement or can be brought, and which supports this additional lever 23 axially on one side.
  • the levers 11, 23, 24 of the lever assembly 9 can be kept in an axially defined position with the solution according to the proposal, without this leading to a high level of manufacturing complexity.
  • the axial extension 27 protrudes through openings 28 in the release lever 24, which further increases the compactness of the structure overall.
  • the actuating lever 11 and the bearing sleeve element 12 form the above-mentioned pre-assembled unit 14 while forming the bayonet lock 13, the pre-assembled unit 14 then subsequently being mounted on the motor vehicle lock 1.
  • the pre-assembly results from the transition from Fig. 2 on Fig. 3 .
  • the assembly of the preassembled unit 14 on the motor vehicle lock 1 also results from the transition from Fig. 3 on Fig. 4 .
  • the motor vehicle lock 1 has a bearing dome 21 mentioned above, the at least one additional lever 23 being attached to the bearing dome 21 in a first step, the preassembled unit being attached to the bearing dome 21 in a second step. Subsequently, it is preferably provided that in a third step the housing cover 8a is otherwise placed on the lock housing 8, whereby the bearing sleeve element 12 is axially supported.
  • the bearing sleeve element 12 is made from a plastic material.
  • the bearing dome 21 is preferably also made from a plastic material.
  • the bearing sleeve element 12 and / or the bearing dome 21 can, however, also be reinforced by other materials, in particular by steel materials. In particular it can be provided that the bearing dome 21 has a steel mandrel for mechanical reinforcement.
