Definitions

  • the present invention relates to a hauling winch and more specifically a winch intended to be mounted at the front of a road vehicle.
  • a first type of winch comprises a drum driven by a wheel and screw couple with control by PTO on the vehicle.
  • the disadvantage of this winch is that it is not very handy and cannot be made free, which makes certain maneuvers impossible, the winch always being dependent on the engine of the vehicle.
  • Another type of winch comprises a reduction gear external to the drum mechanically driven by the vehicle or by a hydraulic or electric motor.
  • the drawbacks of this type of winch are the same as for the previous winch, the latter also having a large footprint and being, therefore, difficult to accommodate.
  • winch consists of a differential winch with internal mechanism comprising a clutch declutching system, without any locking.
  • the disadvantage of this device is that the winch can be made free even when a relatively large load is exerted on the drum because the clutch clutch dog has no locking.
  • the present invention seeks to remedy these drawbacks by providing a towing winch with differential system, of very practical use since the drum can be disengaged when desired, without however this disengagement can be obtained when tension is exerted. on the cable.
  • the means for locking in rotation of this latter ring are constituted by a dog with axially displaceable double toothing, the internal toothing of which is slidably mounted on the hub of the crown which can be locked in rotation and the external toothing of which is mounted with angular play in an internal toothing integral with the chassis, means being provided to ensure the locking in translation of the dog clutch when the external toothing thereof is engaged with the internal toothing integral with the chassis.
  • This maneuver can be followed by the translation of the dog clutch and, consequently, by the release of the differential system and of the drum on which the cable is wound.
  • the means of locking in translation of the dog clutch when the external toothing of the latter is engaged with the internal toothing integral with the chassis are constituted by a flange mounted at the end of the dog clutch and having regularly distributed openings, located at equal distance from the axis, and by a number of fingers corresponding to the number of openings, occupying the same angular distribution as these, parallel to the axis of the winch, and integral with a fixed part, each finger having an enlarged head, of diameter smaller than that of each opening, the angle formed by a straight line passing through the axis of the winch and tangent to a finger and by a straight line passing through the axis of the winch and tangent to the head of a finger being less than or equal to the angular clearance between the external toothing of the dog clutch and the internal toothing integral with the frame.
  • the external teeth of the dog clutch engage with the internal teeth secured to the chassis.
  • the fingers fixedly mounted on the chassis, not being centered with respect to the openings presented by the dog clutch flange, the heads of these prevent the fingers from coming out of the flanges.
  • this winch comprises means for returning the dog clutch to the position in which its external toothing is engaged with the internal toothing integral with the chassis.
  • This winch comprises a chassis 2, which can be fixed, for example at the front of a road vehicle. At the periphery of the winch is mounted a drum 3 on which is wound a cable, not shown in the drawing.
  • This winch is a differential system comprising three satellites, each satellite 4 being constituted by three pinions cut in a single block ensuring perfect alignment of the teeth.
  • Each satellite comprises a pinion 5 meshing with the central drive pinion 6, a pinion 7 meshing with a crown 8 secured to the drum 3, and a pinion 9 meshing with a crown 10 capable of being locked in rotation to serve as a support. to the differential system.
  • the means for blocking the rotation of the crown 10 consist of a dog clutch 12 with axially displaceable double toothing, the internal toothing of which 13 is slidably mounted on the hub integral with the crown 10, and the external toothing of which 14 is mounted with play angular 15 in an internal toothing 16 secured to the chassis.
  • the dog 12 has, on its end face, a flange 17 in which are formed regularly distributed openings 18 and located at equal distance from the axis. On a fixed part integral with the chassis are mounted fingers 19 in a number corresponding to the number of openings, occupying the same angular distribution as these, and parallel to the axis of the winch.
  • Each finger has an enlarged head 20, with a diameter less than that of an opening 18.
  • the angle a has formed by a straight line passing through the axis of the winch and tangent to the head of a finger, and by a straight line passing through the axis of the winch and tangent to the body of a finger, is less than or equal to the angular clearance 15 between the external teeth 14 of the dog clutch and the internal teeth 16 secured to the chassis.
  • the movement of the dog clutch is carried out using a lever 22 mounted pivoting about an axis 23 integral with the chassis. Elastic means not shown in the drawing are provided to maintain the dog in position, in the dog clutch position.
  • the invention brings a great improvement to the existing technique by providing a towing drum with differential system, of simple design, very practical to use and very safe.
