Definitions

  • the invention relates to a gear lever for a vehicle transmission of the kind in which the onset of a ratio change is effected by manipulation of the gear lever.
  • gear levers normally comprise an elongate main section, a handle movable relative to the main section and sensor means for sensing the movement of the handle relative to the main section.
  • An object of the present invention is to provide an improved gear lever.
  • a gear lever for a vehicle transmission of the kind in which the onset of a ratio change is effected by manipulation of the gear lever
  • the gear lever comprising an elongate main section, a handle movable relative to the main section and sensor means for sensing said relative movement of the handle, the handle being connected to the main section by elongate connection means which during movement of the handle transverse to the main section constrains the handle to follow a path in the gear change direction.
  • the gear lever has an elongate tubular spring with one end connected to the elongate main section of the gear lever at a position adjacent the handle.
  • the opposite end of the spring is connected to rod extending from the handle so that the connection with the rod, and hence the handle is well inboard of the free end of the elongate main section. That is disadvantageous and not only leads to a somewhat complex concentric arrangement of gear lever components but also to the need to provide a separate pivot for the handle remote from the free end of the main section.
  • connection means in the present invention may be secured at one end to the handle at a position adjacent a free end of the main section.
  • the connection means may also be secured to the main section itself at a position inward of the free end with the connection means preferably extending alongside the main section.
  • connection means may comprise two spaced apart members which may be arranged on opposite sides of the main section. In that way, the members may be arranged to move together e.g., substantially after the fashion of opposite sides of a parallelogram type linkage as the handle moves relative to the main section. In that way the direction of relative movement of the handle is controlled whereas in GB-A- 785,365 the handle can move in any direction.

  • connection means is preferably resilient whereby movement of the handle relative to the main section causes the connection means to bend resiliently e.g.,about one end.
  • the resilient connection means is rigidly secured to the handle and the main section and may be in the form of an elongate leaf spring.
  • two leaf springs are connected to the main section and handle in such a way that they will bend only in the gear change direction, e.g., in parallelogram fashion.
  • connection means may be arranged within the handle for compactness and to enhance appearance of the gear lever.
  • the handle may extend from said one end of the connection means and, in such a case the connection means may be housed within a gaiter or other suitable cover.
  • the sensor means may comprise a first part associated with the handle and a second part associated with the main section.
  • first and second parts of the sensor means are mounted on respective first and second mountings which are slidable one upon the other during movement of the handle relative to the main section.
  • one of the mountings is formed with a slot which slidably receives a projection on the other of the mountings.
  • One of the mountings may be carried by one of the handle and main section and the other of the mountings engages the other of the handle and main section.
  • Said other of the mountings may be formed with a recess which receives a projection on the other of the handle and main section.

  • the shank 15 carries a transverse plate 24 on which is mounted a pin 25 extending coaxially through the liner 23.
  • the pin 25 carries upper and lower shock absorbing rings 26, 27 respectively which fit firmly into the liner 23 so as to lock the barrel 18 in a rotational sense to the shank 15.
  • a washer 28 is placed on the upper shock absorbing ring 26 and a snap ring 29 locates in a groove 30 in the pin 25 to secure the barrel 16 axially on the shank 15.
  • An electrical lead 55 extends from the sensor 52a, 52b of switch 50 through a bore 56 in the sleeve 39.
  • the lead then extends alongside leaf spring 37, through a bore 57 in flange 33 and then along the outer periphery of the barrel 16 beneath a cover 58 and through a flexible sleeve 59 to electronic circuitry (not shown) for controlling the clutch and accelerator of the vehicle during a ratio change.
  • the gear lever will normally be used to operate a transmission having a typical H-gate pattern for the gear change plus reverse.
  • Fig.1 the gear lever is shown in the neutral position and will be moved in the direction of arrow A for selection of second, fourth and reverse ratios and moved in the direction of arrow B for selection of first, third and fifth ratios, the gear lever being shifted along the neutral path as appropriate.
  • the gear lever is for use in a system where the intention to change gear is triggered by movement of the gear lever in the directions of the arrows.
  • pressure is applied to the knob in the direction of arrow B by the driver which causes the leaf springs 36, 37 to flex in the direction of arrow B about their lower ends.
  • the springs move after the fashion of a parallelogram linkage thereby causing the sensors 52a, 52b to move relative to the magnet 49 of the Hall Effect switch 50, movement of the sleeve 39 relative to the rod 19 being permitted by the clearance 47.
  • the signal derived from sensor 52b of the switch 50 is transmitted through the lead 55 to the control system to operate the clutch and control engine speed.
  • the knob cannot move sideways relative to the rod 19 during movement of the gear lever along the neutral path in view of the horizontal spacing of rivets 38, 44.

  • the leaf springs 36, 37 normally maintain the vane midway between the two sets of sensors/magnets 52a, 49 and 52b, 49 as shown in Fig. 4. In that position magnetic flux F as shown in Fig 3A passes between magnets 49 and the respective sensors 52a, 52b. Pole pieces 190, 191 may be used to encourage the flux to extends across space 61.
  • the knob 54 is moved in direction A or B the relative movement between the knob 54 and rod 19 will cause the vane to lie between either one sensor and its associated magnet or between the other sensor and its associated magnet as shown in Fig. 3B.
  • the vane 62 thereby interrupts the flux F as shown.
  • the interruption is sensed by the sensor which then provides the signal required for selection of ratio.
  • the sensors and magnets could be- positioned so that movement of the knob 54 relative to rod 19 effectively causes the vane to move from between one sensor and its magnet or from between the other sensor and its magnet to restore the flux to that sensor and thereby provide the signal.

Abstract

Le levier de changement de vitesse est de ceux qu'il faut actionner pour provoquer un changement de rapport. Le levier de changement de vitesse se compose d'une partie principale allongée (12), d'un manche (13) qui est mobile par rapport à la partie principale et d'un dispositif détecteur à effet Hall (50) pour détecter les mouvements relatifs du manche. Le manche (13) est relié à la partie principale (12) au moyen de ressorts à lames espacés (36, 37) qui s'étendent longitudinalement le long de la partie principale. Si l'on bouge transversalement le manche (13) par rapport à la partie principale (12), les ressorts (36, 37) fléchissent et obligent le manche (13) à suivre une trajectoire sensiblement linéaire, dans la direction où se fait le changement de vitesse.
