Definitions

  • the invention relates to a lock, in particular a lock for a door Motor vehicle, according to the features of the preamble of the claim 1.
  • Such a lock is known from DE 41 31 891 A1. It is shown and described that on a support plate, which is part of a housing, several lock elements are arranged. These lock elements it is a rotary latch (blocking element), transmission lever and the like, which are arranged on trunnions arranged on the support plate.
  • the lock according to the invention with the characterizing features of Main claim has the advantage that the realization of Lock functions Movements of lock elements within the Lock are arranged, can be transmitted to the outside and vice versa, ensuring that due to the presence of a Lubricant ensures the function over the life of the lock is; at the same time, the lubricant takes on the function of sealing the Lock elements, which are arranged within the housing, opposite the external environment when using a lock in a door (alternatively in a trunk hood, fuel filler flap, tailgate or the like) to impair functionality or can even lead to lock failure, if moisture or contaminants get inside the case can penetrate. This is done with the lubricant that has a seal represents effectively avoided.
  • the housing has a socket that the Wave picks up.
  • This has the advantage that the inner diameter of the socket is matched to the outer diameter of the shaft, so that only a small amount Tolerances exist and thus the sealing effect, in addition to that Lubricant, is reinforced.
  • a socket is advantageous if that Housing made of plastic and the shaft made of a metal to the To improve sliding properties.
  • the housing or the socket takes a tube or the like, the shaft being mounted coaxially in the tube.
  • a function transfer via the Pipe another function transfer can be done via the shaft, which is independent or can be coupled together.
  • a variety of functions achieve the required sealing effect.
  • the housing or the socket has recesses in which the lubricant can be introduced.
  • This has the advantage that not just the sliding surfaces of the shaft and the housing or the bushing can be provided with lubricant, but that there is an additional supply of lubricant by means of which the seal is made.
  • the recesses can be created in this way be that the material of the housing or the socket is so porous is that the lubricant is stored in the pores.
  • the shaft has recesses, into which the lubricant can be introduced.
  • the same statements apply here and advantages already with regard to the recesses in the housing or the socket are present.
  • the Recesses both in the housing or in the socket as well be introduced into the shaft.
  • the recesses are one or more circumferential grooves formed.
  • This has the advantage that always one or more annular pads of lubricant are present so that the sufficient Lubrication of the sliding surface is guaranteed with simultaneous compliance the required sealing against external environmental influences.
  • the grooves are only at least partially circumferential or spiral are circumferential, with spiral circumferential grooves the advantage have that due to a rotation of the shaft always a small amount of lubricant towards the outside or the inside of the housing is transported so that these small amounts, which then in the transition area between the housing surface and the shaft surface accumulate, also collect dirt particles (dust, sand or the like), which reinforce the sealing effect against environmental influences.
  • the recesses are provided with a lubricant depot , which is arranged in particular in the shaft, connected.
  • a lubricant depot which is arranged in particular in the shaft, connected.
  • Such a lubricant should be used for this purpose, which has sufficient adhesive forces to cover the entire surface of the Shaft located in the area of the housing or the socket, to "wet" and at the same time possess sufficient cohesive forces to the lubricant in the lubricant depot in the area to convey the sliding surface.
  • it will be a act as a gel lubricant.
  • the lubricant depot is via a filling opening can be filled with the lubricant. This means that the lubricant depot in the housing of the bushing and / or the shaft with a sufficient amount of lubricant that is sufficient for the life of the lock. This process can be done manually or automatically.
  • this housing 1 can also be part of a support plate, which is closed by a lid becomes.
  • a bushing 2 is arranged after a hole has been drilled, which receives a shaft 3, this shaft 3 on one end 4 for example, not shown actuating elements, wherein an actuation this actuating element by means of the shaft 3 on a lock element transferred to the inside of the housing 1 at the other end 5 of the shaft 3 becomes.
  • lock element again, for example, a lever, a pawl or something else Lock element that can be driven manually or, for example, by a motor.
  • the shaft 3 is coaxial in a tube and the tube in turn in the socket 2 or in the housing (essentially vertically penetrating).
  • the lock elements are then arranged on the tube itself.
  • One or more are at least partially on the outer circumference of the shaft 3 (Advantageously) all-round grooves are present, in which a Lubricant is located, which has at least the task of a seal between the areas (when viewing the figure) above and below the Ensure housing 1.
  • a Lubricant is located, which has at least the task of a seal between the areas (when viewing the figure) above and below the Ensure housing 1.
  • the socket 3 optimally matched to each other, has the lubricant no lubrication function, just a sealing effect. Complementary it can also have a lubricating effect.
  • a lubricant depot 7 is arranged within the shaft 3, which can be filled via a filling opening 8.
  • the lubricant depot will introduced with the manufacture of the shaft 3 and via the filling opening 8 filled with the lubricant, the lubricant depot 7 in connection stands on one or more grooves 6. This ensures that it is always sufficient Lubricant is at least available for sealing.
  • Such an embodiment also applies analogously to the coaxial arrangement of Shaft and tube, on the one hand - as shown in the figure - recesses (circumferential grooves) in the shaft, on the other hand the recesses also in the Pipe (inside and / or preferably outside) are arranged, so that the very good sealing effect is achieved even with this coaxial arrangement becomes.
  • Such a seal is otherwise particularly necessary when inside the housing electrical or electronic components and circuits are present, which are compared to the harsh environmental influences, such as they prevail, for example, inside a motor vehicle door, effectively sealed Need to become. These are negative environmental influences especially the smallest dust and other dirt particles as well as moisture, that are harmful to these electronic components and circuits.
  • the seal via the lubricant ("grease cushion"), one becomes Impairment of the functioning of at least the mechanical components, if not also the electronic components, effectively avoided and the functionality of the lock over the lifespan.
