Definitions

  • the present invention relates to an activation system disengageable from a functional vehicle automobile.
  • the invention relates to a system of the type comprising a pinion of which a portion toothed is adapted to cooperate with drive means, associated for example with an electric motor, and having a central recess in which is mounted rotating a tubular organ activation shaft functional, and in which a crew is arranged axially movable with a pin whose ends protrude radially on either side of the tree, in axial lights of it, and movable to against elastic biasing means, between a first clutch position, in which the radial protruding parts of the pin extend in corresponding radial recesses of the pinion and a second retracted position, in which the parts in radial projection of the pin extend out of the corresponding recesses of the pinion, to allow manual activation of the functional organ.
  • Such disengageable activation systems are already used for example in roof mechanisms opening of motor vehicles which are maneuverable either through an electric geared motor or manually in case of failure of this gearmotor.
  • the activation mechanism since the training means must be irreversible for reasons of safety, the activation mechanism must be disengageable to allow manual activation by a user from inside the vehicle cabin.
  • the user has a tool any such as for example a crank it introduced into the tubular organ activation shaft functional to repel its mobile equipment, in order to release the radially projecting parts of the pin of the corresponding radial offsets of the pinion.
  • a tool any such as for example a crank it introduced into the tubular organ activation shaft functional to repel its mobile equipment, in order to release the radially projecting parts of the pin of the corresponding radial offsets of the pinion.
  • the user can then rotate the tree to operate the functional organ, insofar as it is decoupled from the drive means.
  • these holding means in position are formed by an annular portion solid with the rest of the pinion, this portion annular extending around the central recess of this pinion to hold the pin in position.
  • the object of the invention is to propose a variant making this ring to allow it to perform additional duties.
  • the invention relates to a system disengageable activation of a functional organ of motor vehicle, of the type comprising a pinion of which a toothed portion is adapted to cooperate with drive means and having a central recess, in which a tubular activation shaft is rotatably mounted of the functional organ, and in which is arranged an axially movable assembly provided with a pin whose ends protrude radially from the side and on the other side of the tree, in axial lights of it, and movable against means of solicitation elastic between a first clutch position, in which the radial protruding parts of the pin extend in corresponding radial recesses pinion and a second retracted position, in which the radial projections of the pin extend outside the corresponding recesses of the pinion, to allow manual activation of the organ functional and means for holding in position the pin in the moving part, characterized in that the holding means comprise a ring fitted to force on a span of the pinion and having poles magnetic of opposite
  • a disengageable activation system can be used to activate a functional organ of a motor vehicle such as for example a sunroof.
  • this system has a designated gear by the general reference 1 in these figures, one of which toothed portion for example 2 is adapted to cooperate with training means designated by the reference general 3 in these figures.
  • These training means can for example include another pinion adapted to cooperate with a worm screw activated by an electric motor, by direct current example.
  • this pinion 1 has a recess central designated by the general reference 4 on these figures, this central recess being adapted to receive rotating a tubular shaft for activating the organ functional designated by reference 5 in these figures, and in which is placed a mobile equipment designated by the general reference 6.
  • This mobile assembly can be moved axially in the tree and is provided with a pin designated by the general reference 7 whose ends protrude radially on either side of the tree through corresponding axial lights thereof.
  • the radial protrusions of the pin are designated by the references 7a and 7b respectively and the axial lights of the shaft by the references 5a and 5b.
  • this moving part 6 and therefore this pin 7 are mounted movable against the action of means of solicitation elastic 8 formed for example by a spring housed in the tubular shaft, between a first position clutch shown in Figure 1, in which the radial projections 7a and 7b of the pin extend in radial recesses respectively 1a and 1b of the pinion 1 and a second retracted position of clutch, in which these projecting parts 7a, 7b of the pin extend out of the corresponding recesses 1a, 1b of the pinion, to allow activation manual of the functional organ.
  • means of solicitation elastic 8 formed for example by a spring housed in the tubular shaft
  • the tool and the tubular shaft can be threaded and tapped for allow the coupling of this tool and this shaft, this coupling then making it possible to repel very easily the moving part towards its retracted position.
  • the roof actuation mechanism opening is connected to a pinion for example 10 provided on the tubular shaft 5, for example at its opposite end to that associated with the pinion 1.
  • pin 7 is simply engaged in a recess transverse of the moving part 6 and in the axial lights of the shaft 5 and that there is keep in position to prevent it from coming off of these parts during the operation of this system.
  • the holding means in corresponding positions are formed by a annular portion of the pinion, machined therein to extend around the pin to keep it in position.
  • the means for holding in position the pin include a ring designated by the reference general 11 in these figures, this ring being fitted by force on a bearing 12 of the pinion and extending around the pin to hold it in position.
  • this structure allows greatly simplify the manufacture of this pinion and therefore reduce its manufacturing cost, insofar as this no longer comprising an annular portion coming from material extending around the pin, it can be performed by a technique other than machining such as for example by molding or the like.
  • this ring 11 can also present a succession of magnetic blades of polarities opposite.
  • a type 13 magnetic sensor by example Hall effect, can then be associated with this ring to detect its rotation and deliver rotation information corresponding to means processing (not shown).
  • This ring can for example be made in plastoferrite, and magnetized conventionally for obtain the corresponding magnetic poles.
  • the sensor output information is usable to control the functioning of the system activation in the conventional way.
