Definitions

  • the present invention relates to a starter and more particularly a starter for an internal combustion engine of a motor vehicle.
  • a starter essentially comprises an electric motor and an electromagnetic actuator, the axes of rotation and actuation of which are parallel and which are fixed to a starter frame comprising at least one starter nose forming a cover which envelops on the one hand the end of the output member of the electromagnetic actuator driven by an alternating axial movement and, on the other hand, the free end of the armature shaft of the motor which carries a starter launcher, and comprises an actuating lever which controls the axial movements of the launcher, which is pivotally mounted about a geometric axis substantially perpendicular to the axes of the motor and of the electromagnetic actuator, one end of which is connected to the output member of the electromagnetic actuator, the other end of which, in the form of a fork, acts on a ring of the starter.
  • starter chassis comprises a transverse plate extending in a plane perpendicular to the axes of the actuator and of the engine, and a starter nose.
  • the actuating lever is produced therein in the form of a part, the central part of which is crossed by a hinge pin, the ends of which are received in a part forming a bearing having a stirrup silhouette and which is attached to the plate. starter frame.
  • the assembly and mounting operations of the actuating lever in order to allow its pivoting are particularly complex and costly.
  • the object of the present invention is to propose a starter design of the type mentioned above, in which the means for enabling the pivoting mounting of the actuating lever are of particularly simple design and allow reduced assembly operations and easily automated.
  • the invention provides a starter of the type mentioned above, characterized in that the actuation lever comprises a hinge pin, each of the ends of which is pivotally mounted in a two-part bearing comprising a first bearing part connected to the starter nose and a second complementary bearing part formed opposite in a part connected to the motor casing and / or to the casing of the electromagnetic actuator.
  • the starter 10 illustrated in FIG. 1 comprises a starter frame, the main element of which is a starter nose 11 produced in the form of a molded part on which an electromagnetic actuator 12 and an electric motor 14 are fixed.
  • the stepped front part 16 of the casing 18 of the electromagnetic actuator 12 is fitted into a corresponding part of the rear face 20 of the starter nose 11 while a front part 22 of the casing 24 of the electric motor 14 is also received in a part corresponding (not shown) of the starter nose 11.
  • the electromagnetic actuator 12 and the electric motor 14 can be fixed to the starter nose 11 by fixing screws (not shown).
  • the electric motor 14 which can also be a geared motor, comprises an output shaft, or armature shaft 26, the free end 28 of which projects from the front part of the casing 24 and which is received in the starter nose 11 carries a launcher 30 linked in rotation to the shaft and which can be moved axially along this shaft by means of a pivoting actuating lever 32 whose control is ensured by the electromagnetic actuator 12.
  • the actuating lever 32 is pivotally mounted about a geometric axis XX which is perpendicular to the plane of Figure 1 containing the axis of rotation of the armature shaft 26 of the electric motor 14 and the longitudinal axis of l output member 34 of the electromagnetic actuator 12.
  • the electromagnetic actuator 12 is of a known structure, which will not be described in detail and allows, in addition to the supply of electrical energy to the motor 14 by a system called contactor, to cause the pivoting of the actuating lever 32 by l through its outlet member 34, the free end of which carries a transverse pin 36 which is received in a groove 38 formed at the upper end 40 of the actuating lever 32.
  • the lower part 42 of the actuating lever 32 has a form of fork which cooperates with a control range 44 of the launcher 30.
  • the lever 32 is a part made by plastic molding and its hinge axis is constituted by two opposite sections 46 of a cylindrical axis which extend from opposite faces of the body lever 32.
  • Each axis section 46 is rotatably mounted in a two-part bearing.
  • Each bearing comprises a first concave cylindrical half-bearing 48 and a second complementary concave cylindrical half-bearing 50.
  • the first two half-bearings 48 are formed at the end of a plate-shaped part 52 which projects from the internal face 13 of the starter nose 11.
  • the plate 52 is produced by molding with the starter nose 11 and extends in a plane containing the axis X-X and which is parallel to the axes of the electromagnetic actuator 12 and the electric motor 14.
  • the plate 52 is positioned so that the axis X-X is located in a horizontal plane, considering FIG. 1 which extends between the casings 18 and 24 of the electromagnetic actuator 12 of the electric motor 14.
  • the front part of the plate 52 has a central clearance 54 which gives it a fork shape so as to allow the pivotal movements of the central part opposite 56 of the actuating lever 32.
  • the two second concave cylindrical half-bearings 50 are formed at the end of the front portion in the form of a rectangular plate 58 of a mounting block 60, the rear part 62 of which is mounted between the front parts 16 and 22 of the housings 18 and 24 of the actuator 12 and of the motor 14.
  • the wedge 60 is a plastic molded part, the front part of which is a horizontal plate which extends in a plane which, in the assembled position as illustrated in FIG. 1, coincides with the plane of the part in the form of starter nose plate 52 11.
  • the front part 58 also includes a clearance 64 to allow the pivoting movements of the corresponding face 66 of the central part of the body of the actuating lever 32 around the sections 46 of the articulation axis.
  • the rear part 62 of the mounting block 60 is a vertical plate which extends in a plane perpendicular to that of the front part 58 and which comprises a first concave cylindrical surface 66 which is complementary to the convex cylindrical surface of the front part 16 of the casing 18 of the electromagnetic actuator 12.
  • the rear part 62 comprises a second concave cylindrical support surface 68 which is complementary to the convex external cylindrical surface of the front part 22 of the casing 24 of the electric motor 14.
  • the plate-shaped rear part 62 is thus fitted between the two cylindrical front parts of the electromagnetic actuator 12 and of the electric motor 14.
  • an indexing and mounting finger 70 which extends radially downwards projecting from the concave cylindrical bearing surface 68 to be received in a complementary recess formed in the front part 22 of the casing 24.
  • the shim is thus positioned and is held in position between the two main elements of the starter.
  • the mounting of the actuation lever 32 is therefore particularly simple since it is supported on the two second concave cylindrical half-bearings 50 of the mounting shim 60, the articulation bearings proper being reconstituted during the operation d final assembly of the starter nose 11.
  • the manufacturing costs of the articulation means are particularly reduced insofar as the first half-bearings 48 are produced integrally during the molding of the starter nose 11 and insofar as the second half-bearings 50 are formed at the end of a plastic block 60.
  • the mounting operations are particularly simplified because they do not require any operation of introducing an axis in its general direction or of deformation or spacing of the workpiece to introduce the axis.
