Definitions

  • the present invention relates to an arrangement for controlling a lock, fitted to a motor vehicle, by means of a lock.
  • the invention more particularly relates to an arrangement for the mechanical transmission of a rotational movement between a rotary output member, belonging to a lock of a motor vehicle, and a rotary input member, the rotation axis of which is not coaxial with that of the output member, belonging to a mechanism of a lock, by means of a transmission shaft.
  • the motion transmission between the lock rotor, or any other rotary output member thereof, and an input member of the lock mechanism can be provided by means of an intermediate transmission element which can be a linkage and preferably a transmission shaft of simple design and allowing the clearance-free angular drive of the lock mechanism to which it can transmit relatively large torques.
  • each of the two opposite ends of the transmission shaft, front and rear is rotatably connected to one of the two rotary, output and rotary members. entry respectively by an articulated transmission joint allowing relative angular displacement between the axis of the transmission shaft and the axis of rotation of the corresponding rotary member, and a relative axial displacement.
  • Such a relative axial displacement of the transmission shaft with respect to the output and input members is firstly a generator of noise and wear and, secondly, it does not allow to mount the shaft of transmission "blind" to the lock.
  • the invention proposes an arrangement for the mechanical transmission of a rotational movement between a rotary output member, belonging to a lock of a motor vehicle, and a rotary input member whose axis of rotation is not coaxial with that of the output member, belonging to a mechanism of a lock, and a device, which comprises a transmission shaft, for the mechanical transmission of a rotational movement between the rotary output member and the rotary input member, of the type in which each of the two opposite ends of the transmission shaft, front and rear, is rotatably connected to one of the two rotary, output and respectively, by an articulated transmission joint allowing a relative misalignment between the axis of the transmission shaft and the axis of rotation of the corresponding rotary member, the front transmission joint being a seal of Cardan comprising technical means that longitudinally immobilize the transmission shaft relative to the rotary output member, the forward end of the transmission shaft being received in an open housing of axial orientation formed at the free end of a rear sleeve of
  • the arrangement 10 illustrated in Figure 1 comprises a latch 12 which has been shown only a stator 14, which is for example intended to equip a motor vehicle door, and its rotary output member 16 which is rotatably mounted in the stator 14 around an axis A1.
  • the rotary output member 16 is axially connected to an inner member 18 by an elastic ring 20, or circlip, radially received in a groove 22.
  • the latch 12 is intended to drive in rotation a lock mechanism which is schematically shown a rotary member 24 of movement input which is intended to rotate relative to a lock housing not shown in the figures, about an axis rotation A3.
  • the motion transmission between the rotary output member 16 and the rotary input member 24 is ensured by means of a transmission shaft 26, with a longitudinal axis A2, both of which opposite longitudinal ends, front 28 and rear 30, are respectively rotatably connected to the output member 16 and the input member 24 each by an articulated transmission joint allowing a misalignment between the axis A2 of the transmission shaft 26 and the axis of rotation A1, A3 of the corresponding rotary member 16, 24.
  • the articulated transmission joint arranged at the rear end 30 is constituted essentially by a hinge sphere 32 which comprises two diametrically opposite radial arms 34 which extend outwards, this assembly being received in the end open tubular 36 vis-à-vis the rotary input member 24 whose inner cylindrical housing38 is complementary to the dimensions of the sphere 32 and which has two axial open slots 40 which receive in sliding and rotation arms 34.
  • This known design makes it possible to introduce axially, from front to back, the end 30 into the member 24.
  • the articulated transmission joint which connects the front longitudinal end 28 of the transmission shaft 26 to the rotary output member 16 is an articulated cardan joint, that is to say whose two axes are concurrent and immobilizes longitudinally two components articulated together around a center of rotation.
  • the cardan joint comprises a hinge sphere 42 which is received axially in a cylindrical bore 44 of axis A1 formed in a tubular extension 46 of rear longitudinal end of the rotary output member 16.
  • the hinge joint comprises a cylindrical hinge rod 48 which extends diametrically along a perpendicular axis A4 and coinciding with the axis A1, and which is mounted in the tubular extension 46 in the manner of a diametrical pin.
  • the hinge sphere has a circular hole 50 through which the hinge pin 48 extends vertically with a slight clearance so as to allow relative rotation of the sphere 42 relative to the fixed hinge pin 48 around the axis A4.
  • the circular hole 50 is arranged in an axial plane of the transmission shaft 26 and in a diametral plane of the sphere 42 centered on the axis A2, and it extends vertically, upwards and downwards (considering the Figures 1 and 2), by an upper guide slot 54 and lower 56.
  • the two slots 54 and 56 are symmetrical with respect to the median vertical plane corresponding to the section plane of FIG. 2 and relative to the median horizontal plane in which the circular hole 50 extends.
  • each of the guide slots 54 is, as can be seen in particular in FIG. 3, equal to the diameter of the hole 50 and is thus substantially equal to the diameter of the articulation rod 58.
  • Each of the two slots 54, 56 which extends in a median vertical plane of the transmission shaft 26 has a flared profile opening respectively upwardly and downwardly and which, in the example illustrated in the figures, is a V profile.
  • the articulation sphere 42, and therefore the transmission shaft 26 can rotate in both directions around a transverse axis A5 perpendicular and concurrent to the axis A4 of the rod hinge 48, that is to say that, overall, the front longitudinal end 28 of the transmission shaft 26 is hinged relative to the output member 16 by a cardan joint whose center of rotation C, corresponding to the intersection of the axes A4 and A5, corresponds to the point of competition of the axes A1 and A2.
  • a weakly calibrated spring 60 of initial alignment of the axes A1 and A2 is arranged around the transmission shaft 26 between its front end 28 and the tubular extension 46.
  • the flared V-shaped profile of the slots 54, 56 allows an angular displacement of the transmission shaft 26 about the axis A5 which is for example equal to 30 ° on either side of the aligned position illustrated in Figure 2 , the angular displacement of the transmission shaft 26 about the axis A4 being determined by the abutment of the longitudinal end front 28 against the circular edge which surrounds the rear end of the bore 44.
  • the transverse width along the axis A5 is substantially equal to the outer diameter of the hinge rod 48, there is no possibility of rotation of the transmission shaft 26 around its axis A2 with respect to the output member 16 and the rear end 30 of the transmission shaft 26 is thus angularly oriented precisely relative to the output member 16.
  • This characteristic of angular indexing of the articulation sphere 32 with its arms 34 allows, during assembly of the arrangement 10 on a vehicle, and in particular during the axial insertion blind of the rear end 30 in the rotary input member 24, d angularly orient these two elements, the original angular position of the output member 16 relative to the stator 14 resulting from the design of the latch 12.
  • the convex hinge sphere 42 is guided in rotation in a concave complementary spherical surface portion 62 formed in the bore 44 of the output member 16.
  • the output member 16 is made in two parts.
  • a first rear portion 16A is a part whose general design corresponds to that of the output member 16 in one piece shown in Figures 1 and 2 and previously described.
  • the second front portion 16B is rotatably mounted relative to the portion 16A, about the axis A1, with a limited relative angular deflection possibility.
  • the rear longitudinal end circular edge 64 of the front portion 16B comprises an axially oriented lug 66 which is received in a peripheral arcuate groove 68 formed in the peripheral circular edge 70 vis-à- screw of the front part 16A.
  • the two angular ends 72 of the groove 68 in cooperation with the tab 66, define the relative angular travel of the two parts 16A and 16B.
  • the portion 16A has a slot 74 for the radial insertion of the elastic ring 20 which provides the mutual axial retention of the two parts 16A and 16B.
  • the hinge pin 48 constitutes a vertical branch of radial orientation of a single element 76 in folded piano string.
  • the hinge pin 48 is extended externally by an axially oriented leg 78 which extends axially forward to extend through a notch 80 formed in the edge 70 of the rear portion 16A. to penetrate inside the open rear face of the rear portion 16B.
  • the axial branch 78 can be received in an axial notch or groove 82 formed in the inner annular cylindrical wall 84 of the rear portion 16B between two flats 86 which extend along a rope.
  • the axial branch 78 is elastically deformable in a radial direction so as to allow its escape from the groove or notch 82 to allow limited rotation between the two parts 16A and 16B.
