Definitions

  • the present invention relates to rotary contactors, in particular for motor vehicles, of the type comprising two coaxial parts mounted movable in rotation relative to each other against a flexible electrical connection strip wound between said parts, by being coupled at one of its ends to one of said parts and at the other of its ends to the other of said parts.
  • the flexible tape comprises one or more electrical conductors and an insulator to insulate the conductors between them, and allows an electrical connection between the two parts without micro-cutting.
  • this ribbon is wound and unwound, and must be of great length to satisfy the rotation of the order of 5 turns necessary on most motor vehicles, this rotation being limited by stops or by the pulling of the ribbon .
  • the length of the tape is therefore variable depending on the winding and unwinding diameters; in general, the length of these strips is of the order of 3 to 6 meters and is included in the cost of the rotary contactor for a large part, in particular depending on the number of channels, or conductors, that said strip has.
  • the inner diameter of the hub is a function of the diameter of the steering shaft passing through the fixed steering column of the vehicle and has an imposed value.
  • a rotary contactor has already been proposed in the above application in which one of the parts comprises a hub that is movable in rotation and the other part has a fixed hollow housing, said contactor comprising, on the one hand, a rotor mounted rotating in the housing, and, on the other hand, a planetary gear train, carried by the housing, the hub and the rotor, for rotating the rotor by the hub and increasing the number of revolutions between the hub and the housing, the rotor having passage means for the flexible strip and carrying in rotation a pinion capable of meshing with a toothing formed inside the housing and a toothing formed on the hub outside of it.
  • the object of the present invention is to avoid this drawback.
  • a rotary contactor in particular for motor vehicles of the kind comprising two coaxial parts mounted movable in rotation relative to one another, against a flexible electrical connection strip wound between said said parts being coupled at one of its ends to one of said parts and at the other of its ends to the other of said parts, in which one of said parts comprises a hub movable in rotation and the other part a fixed hollow housing inside which the hub is housed, which contactor comprises, on the one hand, a rotor mounted for rotation in the housing, and, on the other hand, a planetary gear train, carried by the housing, the hub and the rotor, for rotating the rotor by the hub and multiplying the number of revolutions between the hub and the housing, the rotor having means of passage for the flexible tape, in which the rotor rotates a clean sprocket e to mesh with a toothing formed inside the housing and a toothing formed on the hub outside of it, is characterized in that the teeth of the pinion are elastic transversely, that
  • the elasticity of the teeth is obtained by virtue of a generally radially extending slot which the teeth have in their middle part.
  • the slot is straight; alternatively, it is oblong in shape.
  • the usable flank of each tooth is in the involute of a circle and its connecting flank is of the concave type.
  • the slot extends radially to the bottom surface of the pinion.
  • the rotor carries a pin for rotationally mounting the pinion, and the teeth of the housing and the teeth of the hub are continuous.
  • the active surface of the teeth is inclined, forming, with a direction parallel to the axis of the pinion, a so-called relief angle, so that the pinion is subjected to an axial force which presses it against the rotor, which further minimizes train operating noise; the teeth with which the pinion cooperates are straight teeth.
  • the passage means consist of a slot made in an annular skirt of axial orientation, which has the rotor for winding the flexible tape, and one of the sides of the slot has a rounded shape for turning over said tape.
  • the appearance of play is avoided, on the one hand, between the pinion and the toothing of the hub and, on the other hand, between the pinion and the toothing of the housing; this avoids the appearance of noise.
  • FIGS. 1 to 12 a rotary contactor for a motor vehicle of the kind comprising two coaxial parts 2, 7 mounted movable in rotation relative to each other against a flexible strip 8 of electrical connection, wound, here in a spiral, between said parts while being coupled at one of its ends to one of said parts and at the other of the ends to the other of said parts.
  • one of the parts comprises a hub 2 movable in rotation capable of being linked in rotation to the steering wheel of the vehicle and a fixed box 7 secured to the fixed steering column of the vehicle via the switch support placed under the steering wheel and not visible .
  • the hub 2 is housed inside the hollow-shaped housing 7.
  • the contactor rotating comprises a rotor 5 rotatably mounted on the hub 2 while being housed in the housing 7 and a planetary gear train 40, 20, 4 carried by the fixed housing 7, the movable hub 2 and the rotor 5 for driving the rotation the rotor 5 through the hub 2 and increase the number of revolutions between the movable hub 2 and the fixed housing 7.
  • the rotor 5 has passage means 51 for the flexible strip 8. These means 51 here consist of a slot described below.
  • the rotary contactor comprises a set of plastic parts, namely a protector 1, the movable hub 2, a tone wheel 3, a pinion 4, the rotor 5, a cover 6 and the housing 7. These parts are of hollow annular shape.
  • the housing 7 is here in one piece and has a bottom 74 of transverse orientation connected at its outer periphery to an annular skirt of axial orientation 72. This bottom 74 is perforated centrally at 70.
  • the skirt 72 has an internal toothing 40 axially limited by a smooth wall of transverse orientation 71 extended by two successive cylindrical walls 73 and 75 of successively increasing diameters.
  • the internal bore of the housing 7 is therefore stepped.
  • the teeth 40, with involute teeth, are axially limited, on the side opposite the transverse wall 71, by the bottom 74 of the housing 7.
  • This housing 7 also includes a lateral opening 76 of substantially rectangular shape to allow the exit of the flexible electrical connection ribbon and the connection to the integrated connectors.
  • a chimney 77 extends radially outwards from the opening 76.
  • the fixed housing 7 is therefore of hollow annular shape and here carries transversely projecting ears 78 for fixing the housing 7 to the switch support placed under the steering wheel of the vehicle and connected to the end of the steering column.
  • this box 7 can be produced directly in the central part of said switch support, which allows a reduction in the number of parts.
  • the steering shaft crosses centrally the switch support, the housing 7, the rotor 5 and the hub 2 drilled for this purpose.
  • the steering shaft is integral in rotation with the steering wheel.
  • the rotor 5 Inside this housing 7, is housed the rotor 5 around which is wound or unwound the electrically conductive flexible tape 8 comprising, embedded in an electrical insulator, a number of channels or electrical conductors, such as flat conductive wires , determined according to the applications and the number of pieces of information to be passed between the fixed steering column and the rotating steering wheel.
  • This tape partly determines the thickness of the rotary switch.
  • the ends of the conductive tape 8 are secured respectively to connectors 86 and 87; these connectors have an axial orientation, one, the connector 86, being directed upwards and the other, the connector 87, being directed downwards; the connector 86 is adapted to pass through an axial chimney 61 which protrudes from the cover 6 and which extends from the upper face of the latter; thus, the connector 86, when it is placed in the chimney 61, is integral in rotation with the latter; the chimney 61 is the member by which the rotary switch is rotated by the vehicle steering wheel.
  • the hub 2 provided with a sleeve 23, is mounted journalling on the housing 7 thanks to a cylindrical bearing surface 21 which it has and which is adapted to cooperate with the edge of the central hole 70 of the housing 7.
  • a flange transverse 22 borders the cylindrical surface 21 and constitutes for the hub 2 an axial stop in cooperation with the external face of the bottom 74 of the housing 7.
  • the sleeve 23 of the hub 2 is provided with two longitudinal notches 24 intended to receive drive pins 62 provided on the internal face of a skirt 63 carried by the annular flange 64 of the cover 6.
  • the skirt 63 is split at 65 for the passage of the folded end 81 of the ribbon 8 for its connection to the connector 86.
  • a return 25 of triangular section for the attachment by this return 25 of the upper edge of the skirt 63 of the cover 6.
  • the rotor 5 is generally in the form of a ring and comprises an annular peripheral skirt 52 of axial orientation connected by one of its branches (its lower branch - FIGS. 2, 3 or 7) to a transverse flange 54.
  • This flange 54 door in one piece projecting axially in its lower part, on the side opposite its skirt 52, a pivot 53 intended to receive the pinion 4.
  • the free end of the skirt 63 of the cover 6 allows rotary mounting of the rotor 5 by cooperation, with said free end, of the inner edge of the central opening 56 of the flange 54 of the rotor 5, so that a space exists between the skirt 63 and the internal bore of the skirt 52 for housing the ribbon and winding it around the skirt 63.
  • the skirt 52 is split at 51 for passage of the ribbon 8, the depth of the slot 51 being a function of the height of the ribbon 8.
  • One of the sides delimiting the slot 51 is rounded at 55 to allow the ribbon 8 to be turned over without injuring it as described below.
  • the roundness extends between the skirt 52 and the skirt 63.
  • the hub 2 also has projecting at its external periphery a toothing 20 formed by means of an excess thickness which the hub has at its external periphery at the level of its flange.
  • the epicyclic gear train here has the teeth 40, 20 and the pinion 4 rotatably mounted on the pin 53 of cylindrical shape and thus forming a journal integral with the rotor 5.
  • the pinion 4 rotates the rotor 5 step by step in cooperation with the leading teeth 20 of the hub 2 and the fixed teeth 40 of the housing 7.
  • the combination of the three elements 40, 20, 4 forms a planetary gear train having a multiplier ratio allowing a ribbon of short length.
  • the number of teeth of the toothing 20 of the hub 2 is defined to obtain the multiplier ratio adapted to the dimensions of the rotary contactor, so that the toothing 20 may or may not be continuous.
  • the ribbon 8 is here a multi-conductor extruded cable; its flexibility allows it to undergo the reversal necessary for the operating principle of the rotary switch. Its two ends are bent at 90 °, to allow direct exit to the connectors thus avoiding any intermediate connection.
  • the electrical insulation of the tape 8 is made of generally soundproof material with a low coefficient of friction. It is for example based on polyamide or copolymer and tetrafluoroethylene stable for temperatures between -55 ° and 150 °.
  • the electrical conductors of the ribbon are advantageously flattened wires.
  • the housing 7 includes a housing 79 for a steering wheel angle sensor, the information of which can be processed in particular by the computer of a so-called intelligent suspension system; the position of the steering wheel being represented by that of the cover 6, said angle sensor reads marks 9 traced on a so-called phonic wheel 3, in the form of a ring, secured to the cover '3; this connection is obtained by hooks 66 cooperating with the upper face of the tone wheel 3 and notches 31 formed at the internal periphery of said wheel 3; these hooks 66 apply the wheel 3 elastically against the cover 6, more precisely against stops 67 formed thereon, also elastic by means of radial cutouts which border them.
  • the cable for supplying and transferring information from the sensor is partially shown in 91.
  • a protector 1 of generally annular shape covers and protects the wheel 3 and closes the housing 79 of the sensor; the protector 1 is secured to the housing 7 by means of axial tabs 11 with a hole adapted to cooperate with radial pins 82 formed at the external periphery of the housing 7.
  • the hub 2 linked to the steering wheel has a position which represents that of the latter; it is then possible to use the hub 2 for the control of certain equipment; for example, an axial tongue, such as the tongue 26, can be used for the automatic return of the control of the indicators of the vehicle.
  • the chimney 77 of the housing 7 is in two parts integral with the housing, one of which 77B is fixed relative to it and the other of which 77A is movable relative to the first in the manner of a door thanks to a thin axial hinge 83; the locking in the closed position of the door 77A is obtained by hooking the free axial end 84 of the door 77A on a complementary axial means 85 carried by the housing 7, FIG. 4.
  • the housing 7 carries, in prominence relative to the latter, lateral guides 80 extending axially and intended to guide the ribbon 6 radially, thereby limiting the contact zones of the ribbon 6 with the housing 7 and therefore the friction.
  • the protector 1 carries a mark 10 on its external face, which is therefore a fixed mark relative to the housing 7.
  • the cover 6 also carries a mark 60 making it possible to know its relative position relative to the housing 7; the mark 60 is always visible even when the protector 1 is in place, as well as the tone wheel 3 which has for this purpose a notch 32; another notch, the notch 33, allows the tone wheel 3 to properly surround the chimney 61 with the cover 6.
  • the cover 6 has a window 68.
  • This window 68 is on a radius equal to that on which is placed a reference 50 secured to the rotor 5 so that for a certain angular relative position of the cover 6 and of the rotor 5, the mark 50 of the rotor 5 is visible through the window 68 of the cover 6, the constituent parts of the contactor being placed axially, when the contactor is mounted in the order in which they are shown vertically on the figure 2.
  • the rotary switch is of the type in which the strip is in the central position when the steering wheel is also in the central position, that is to say in the position which corresponds to the right steered wheels.
  • a type is advantageous because it allows the use of a short length ribbon.
  • a flywheel being designed to make five turns in total, it can therefore perform, from this central position, two and a half turns in each direction of rotation, to the left and to the right; it will therefore be the same for the cover 6 and the hub 2 of the contactor.
  • the reduction chosen and obtained by the planetary gear is two and a half, so that when the cover 6, therefore the hub 2, makes five turns, the rotor 5 performs only two turns.
  • the hub 2 and the rotor 5, with its pinion 4, are placed axially in the housing 7, by each of its ends; the door 77A of the housing 7, more precisely of the connector 77, is open.
  • the connector 86 is threaded, from below relative to the cover 6, into its chimney 61; at the end of the race, means not shown lock the position of the connector 86 in the chimney 61 and hold it there axially.
  • the position of the parts is illustrated by the references 10, 50 and 60, although the reference 50 is not visible.
  • the three marks 10, 50 and 60 are aligned along a diameter D; the marks 10 and 60 are diametrically opposite; the mark 50 is in line with the mark 10; the door 77A being open, the strip 8 spreads outside the contactor.
  • the cover 6 is rotated in the direction of the arrow F1, and this over five turns; the rotor 5 then having made two complete turns, the marks 50 and 60 are found in the same position relative to the mark 10; the connector 87 is then in place in the part 77B of the chimney 77 and the door 77A is closed; means not shown also lock the connector 87 in the chimney 77.
  • the ribbon 8 is in the position shown in FIG. 6: a first portion 8A, from the loop 88 to the connector 87, is outside the skirt 52 of the rotor which it surrounds for about one revolution and a second portion 8B, from the loop 88 to the connector 86, is inside said skirt 52 and surrounds the skirt 63 of the cover 6 over approximately two turns.
  • the cover 6 is turned in the direction of the arrow F2; in FIG. 17, the cover 6 has just made one revolution: the rotor 5 has therefore made 0.4 revolution and its non-visible mark is at right of the radius C1; in FIG. 18. the cover 6 has made two turns: the rotor 5 has therefore made 0.8 turns and its mark, to the right of the radius C2, is still not visible; in FIG.
  • the cover 6 has made two and a half turns: its mark 60 is then in line with the mark 10, as is the mark 50 of the rotor 5 then visible through the window 68; thus, when the strip 8 is in the central position, the three marks 10, 60 and 50 are aligned on the same radius, corresponding to the initial diameter D, and all three visible.
  • the pinion 4 has teeth 41, eleven teeth 41 according to the example shown, whose profile is better visible in Figure 12; each tooth 41 is here symmetrical; its usable flank 46 is generally in the involute of a circle and its connecting flank 47 is of the concave type; the tooth 41 is shaped into two half-teeth 41A, 41B by virtue of a slot 45, here radial and rectilinear, which it comprises; thanks to this arrangement, the teeth 41 are provided with a certain transverse elasticity, that is to say in the circumferential direction relative to the pinion 4; advantageously, the slot 45 extends radially up to the base surface 48 of the pinion 4, FIG. 10.
  • This elasticity can be modulated by varying the shape of the slot; thus, for example, the slot 145 of the tooth 141 of FIG. 13 is oblong; the slot 246 of the tooth 241 of Figure 14 is also oblong but more pronounced.
  • the teeth can be mounted in slight compression between the toothing 20 of the hub 2 and the internal toothing 40 or crown of the housing 7: therefore, the planetary gear is without interlocking play and the train operating noise is reduced or even suppressed.
  • the pinion 4 has a central bore 42 followed by a bore 43 of smaller diameter so that the pinion 4 can be stapled on a pivot 53 having a head and integral with the rotor 5.
  • the active surface 49 of the teeth 41 is inclined, forming, with a direction parallel to the axis of the pinion 4, a so-called relief angle 44; therefore, when the pinion is mounted between the teeth 20 and 40 which are straight teeth, the pinion 4 is subjected to an axial force which presses the pinion 4 against the rotor 5, more precisely against a flange 57 of the rotor 5 which surrounds the pivot 53; thus, the pinion 4 works without axial play, which again minimizes, or even eliminates, the operating noises of the planetary gear.
  • the pinion according to the invention it is possible to have several circumferentially, to better balance the forces, without risk of jamming.
  • the hub 2, the pinion 4, the rotor 5, the cover 6, the housing 7 and therefore the planetary gear 40.47 are made of moldable plastic so that noise is further minimized and friction reduced.
