Definitions

  • the present invention relates to a selecting device for automotive vehicles, consisting of a console and an adjustable member arranged in the console, said member being adjustable between various positions, said positions being determined by at least one position-maintaining member extending between the adjustable member and the console, and located within at least one cavity in the console or the adjustable member.
  • Examples thereon are operating devices such as gear selectors for operating the gearbox or transmission of an automotive vehicle.
  • gear selectors exhibit a console and a gear selector lever movable therein, said selector lever being adjustable between different gear positions.
  • the suspension of the selector lever as well as various blocking devices are examples of sources of various vibrations and dead play caused by inevitable tolerance demands.
  • the selector lever may be provided with a pivot shaft extending through a bore, where the play between shaft and bore may cause unwanted play.
  • the object of the present invention is to provide a selecting device, in which the above drawbacks of excess dead play are eliminated.
  • a selecting device characterised in that said cavity exhibits at least two, onto each other converging supporting surfaces for the position-maintaining member, and that the adjustable member is continuously subjected to a force substantially transversal to the position- maintaining member, bringing it into contact with the two supporting surfaces.
  • the comprised components taking part in the co-operation between the adjustable member and its associated console may be manufactured with relatively large tolerances, without causing any play.
  • Fig. 1 shows a cross section through a selecting device according to the invention, in the form of a gear selector for an automotive vehicle
  • Fig. 2 shows a partly interrupted section through the device, taken along the line ll-ll of Fig. 1
  • Fig. 3 shows a partly interrupted section through the device, taken along the line
  • FIG. 1 shows a partly interrupted section through the device, taken along the line
  • FIG. IV-IV of Fig. 1, and Fig. 5 shows a partly interrupted section through the device, taken along the line
  • the illustrated example is a selecting device of the type automotive vehicle operating device, such as a gear selector for operating a gearbox associated with an engine for an automotive vehicle.
  • the gearbox may be either a manual gearbox or an automatic gearbox.
  • the gear selector is intended for an automatic gearbox and, for the sake of clarity, has been given a relatively simple selection movement for selection of various gear ratio positions, in this case a pivoting movement about one single pivot axis has been determined.
  • the selecting device in the following called the operating device, exhibits an adjustable member, in the following called the operating member 1, which is movably arranged in a console 2 that is mounted in an automotive vehicle.
  • the operating member 1 exhibits an operating lever 3 with a lever knob 4, to be gripped by the operator, i.e. the driver, in the case of the operating device being a gear selector. Through manual movements of the lever knob, the operating member is intended for displacement between different operating positions in relation to the console 2.
  • the operating member 1 is movably arranged in the console 2, by means of an operating shaft 5, in the illustrated example affixed to the console, more specifically to two side walls 6, 7 and extending, in the illustrated example, through coaxially arranged bores 8, 9 in the console.
  • the operating shaft 5 may be fixedly arranged in the console or pivotally supported thereby, and will define a geometric pivot axle 10, about which the operating member 1 is pivotally supported between its operating positions.
  • the lever 3 is adjustable through a pivoting motion, substantially in a plane extending through the longitudinal axis 3' of the lever, perpendicularly to the plane of the paper in Fig. 1.
  • the movable position-maintaining member 11 is generally elongated and designed like a pin or plunge, arranged in the operating member 1, in particular in an elongated cavity 15, and being spring loaded so as to bias the pin 11 with a spring force directed along an axis of symmetry 16 in the cavity 15.
  • the spring force is preferably provided by a compression spring, in the illustrated example a coil spring 17, constricted between a fixed seat 18, defined by a shoulder inside the cavity 15, and a shoulder on the pin.
  • the coil spring extends around a guide pin 19 defining a reduced-diameter extension of the pin 11 and being received in a reduced-diameter portion 20 of the cavity.
  • Fig. 1 can further be gathered that the operating member 1 is blocked against movement along the operating axis 10 in the rightward direction by a blocking member 21 in the shape of a stop ring 21 fixedly arranged on the operating shaft.
  • a blocking member 21 in the shape of a stop ring 21 fixedly arranged on the operating shaft.
  • the operating shaft 5 extends through cavities 23, 24 in the operating member.
  • the operating member 1 being divided into two shaft sleeves 25, 26, two separate cavities 23, 24 are defined, arranged facing each other, i.e. aligned with each other, and with a predetermined symmetry relative to the operating shaft 5 and its geometrical axis 10.
  • the operating shaft 5 for the sake of clarity only hinted by a dashed line, is in a conventional manner cylindrical in shape with a cylindrical exterior surface 27, i.e. exhibits a circular circumference in cross-section.
  • the two cavities exhibit cross- sections having a cross-sectional shape deviating from the circular shape, which can also be expressed as being a non-circular shape.
  • a common denominator for the two cavities 23, 24 is that each cavity exhibits at least two supporting surfaces 28, 29, 30, 31 for the exterior surface 27 of the operating shaft 5, converging onto each other.
  • the supporting surfaces are planar, but could conceivably also be curved, having a concave or a convex shape, for example through the cavities exhibiting an oval cross-section shape.
  • the angle between the supporting surfaces should be such that there will be no risk for self-locking, i.e. for the operating shaft 5 to be pinched inside the cavities.
  • the angle between the supporting surfaces is about rectangular, but it could be varied within a wide range. Both supporting surfaces within each pair of supporting surfaces should thus simultaneously form supporting surfaces for the exterior surface 27 of the operating shaft, and a prerequisite therefor is that the operating shaft will not first "reach the bottom" against the transition sections 32, 33 between the supporting surfaces.
  • the transition portion 32, 33 of each cavity should have a smaller radius of curvature than that of the operating shaft 5, whereby an intermediate distance 34, 35 will always be maintained between the respective transition portion and the exterior surface 27 of the operating shaft.
  • the only further requirement on the cavity dimensions and shape is substantially that they can receive the operating shaft 5 with a suitably balanced clearance or intermediate distance to the cavity walls.
  • the other wall sections 36,37,38,39,40, 41 of the cavities are located at such a distance from the opposing wall sections inside the cavities that the operating shaft 5 is received with a certain play relative to its exterior surface 27.
  • the two cavities 23, 24 in the illustrated embodiment are shaped such that their V-shapes are opposed to each other. More precisely, the supporting surfaces 28, 29 are turned so as to converge towards each other in the upwards direction, towards the spring member 17 and the position- maintaining members 11-14, whereas the supporting surfaces 30, 31 in the other cavity 24 converge in the downwards direction relative to said members.
  • the torque described above will create mutually opposed forces on the respective shaft sleeve, 25, 26 and, more precisely, a downward force, see arrow 42 in Fig. 2, on the shaft collar 25, and an upward force, se arrow 43 in Fig. 3, on the shaft sleeve 26.
  • Fig. 2 can be gathered more particularly how the position-maintaining members 11-14 are arranged.
  • the moving position-maintaining member 11, i.e. the pin 11, exhibits a rounded end surface 44 that, through the action of the spring member 17, will always strive to abut resiliently against any internal surface of the console 2, either those guide surfaces 46 defined by the respective fixed position- maintaining members 12, 13, 14, or the intermediate guide surfaces 47.
  • the end surface 44 will abut against said surfaces during the selection movements of the operating lever 3 in either direction of selection, se arrows 48 and 49 in Fig. 2.
  • All fixed position-maintaining members as well as the intermediate guide surfaces 47 are configured so as to be angled in relation to an imaginary radial plane through the pin 11 , whereby the torque will be maintained in all positions.
  • the fixed position-maintaining members 12, 13, 14 are shaped like cavities or recesses having rounded transition surfaces 50.
  • the recesses and the transition portions are shaped so as to define distinct detent or index positions each determining a certain operational function of the operating device but allowing pivotal motion of the lever 3 whilst overcoming the resilient force of the spring member 17.
  • the gear ratio positions will basically comprise a forward drive position D, neutral position N and a reverse position R.
  • a further source of play is eliminated by the principle of the invention, that is, between the moving position-maintaining member 11 and its anchoring in the operating member 1.
  • the moving position-maintaining member 11 or the pin will transfer the positions set against the console 2 to the operating member 1 via its anchoring in the associated elongated cavity 15.
  • the operating member will transfer its pivoting motion around the operating shaft 5, caused by the operator movement of the lever knob 4, to the pin 11 via the cavity 15 and, more particularly, its supporting surfaces against the exterior surface 53 of the pin, see Fig. 4.
  • the exterior surface of the pin is only hinted by a dashed line, showing a circular circumference, i.e.
  • the cavity 15 and the reduced- diameter portion 20 are non-circular in shape, in the illustrated example having supporting surfaces 54, 55, 56, 57 or supporting points, converging in pairs on each other, securing a play-free contact against the respective exterior surface by the supporting surfaces being two in each section and partially opposing each other.
  • an intermediate clearance 55' is created to the pin and its extension, respectively, so as to prevent "bottoming".
  • Fig. 5 being turned in the opposite direction, making the associated supporting surfaces 56, 57 converge in the opposite direction, i.e. in the same direction as arrow 59, a play-free contact against the supporting surfaces is warranted at all times.
  • a play-free position retention of the operating member in its selected operating position is also secured, providing a distinct feeling and reducing the risk of vibration.
