Definitions

  • the switching element in both embodiments described above, a rigidly arranged on the switching element shift finger, which is selectively brought in force-transmitting connection when selecting the shift gate with one of the shift fork arms.
  • the shift finger is pivoted into a correspondingly shaped driving groove in the selected Heidelberggabelarm.
  • the shift rail 2 is arranged centrally.
  • the shift rail 2 is arranged within a gearbox, mounted in a housing 10 and slidably disposed in the axial direction relative to the housing 10 by a shift actuator, not shown.
  • the housing 10 may be the transmission housing itself or a housing within the transmission housing.
  • the axial guidance of the selection element 5 is effected by a pin. This sits firmly in a hole in the housing and protrudes into a slot in the selector element 5 inside. This slot extends perpendicular to the axis of rotation in the circumferential direction in order to allow a rotation of the selector element 5 about the central axis 1 1.
  • the switching element 3 is easily rotatable in this embodiment via a clearance fit and a snap ring 17, but axially mounted on the shift rail 2. But it can also be stored for example by means of a roller bearing.
  • a locking member 9 for locking the unselected shift fork arms 6, 7 and 8, respectively, is shown in FIG. Adjacent to the longitudinal opening 25 through which the shift finger 4 protrudes into the driving groove 29 of the respective selected Wegmülarmes 6, 7 and 8, the locking element 9 is rigidly mounted on the selector element 5. In this example, the locking element 9 is made in one piece with the selection element 5.
  • the switching element 3 has a rigidly arranged on the switching element 3 shift finger 4, which protrudes through a longitudinal opening 25 in the selector element 5 in a driving groove 29 of each selected Druckgabelarmes 6, 7 and 8 into it.
  • the shift finger 4, in conjunction with the longitudinal opening 25 again forms a positive connection for transmitting the selection movement from the selector element 5 to the switching element 4, whereby the selector element 5 performs each rotational movement to select the shift gate together with the switching element 3.
  • the selection movement is triggered here by a Wählaktuator 13, which engages a rigidly arranged on the selector element 5 selection finger 12 and so the selector element 5 together with the switching element 3 about the common center axis 1 1 is rotated.
  • this embodiment as shown in Fig. 5, a rigidly arranged on the selector element 5 locking element 9, which engages in the driving grooves of the unselected shift fork arms 6, 7 and 8 and this fixed to the housing, so that in an axial switching movement the shift rail 2 only the respectively selected shift fork 6, 7 or 8 moves with the shift rail 2.
  • both switch positions are latched in the illustrated embodiment, as can be seen on the both sides of the detent recess 1 6 arranged two locking recesses.
  • the locking recesses can also have different depths and shapes, such as, for example, rounded flanks.
  • the shift rail 2 is displaced in the axial direction of the shift actuator, not shown.
  • the shift rail 2 takes the axially fixed to her parts, namely the switching element 3 with the shift finger 4, the selected Weglarm 6, 7 or 8 with the shift fork 26, 27 or 28 and finally the associated shift sleeve with in the desired switching position.
  • the locking force of Heidelberg einsrast réelle 18 is overcome.
  • the neutral position is initially approached by the shift actuator, then the selection actuator selects the desired shift gate before the shift actuator then switches to the desired target gear.

Abstract

L'invention concerne un dispositif de changement de vitesse à rail de sélection unique (1) pour une boîte de vitesses à plusieurs vitesses comprenant un rail de sélection (2), un élément de changement de vitesse (3) et un élément sélecteur (5). Dans le cas présent, le rail de sélection (2) est disposé de façon à pouvoir coulisser axialement dans un carter de boîte de vitesses (10) et l'élément de changement de vitesse (3) est relié dans la direction axiale fixement au rail de sélection (2). L'élément de changement de vitesse (3) transmet un mouvement de changement de vitesse axial au choix à l'un de plusieurs bras de fourchette de boîte de vitesses (6, 7, 8). L'élément sélecteur (5) est disposé de façon solidaire du carter dans la direction axiale par rapport au carter de boîte de vitesses (10). L'élément de changement de vitesse (3) et l'élément sélecteur (5) peuvent basculer ensemble autour d'un axe médian (11). Selon l'invention, il est prévu un encliquetage (18) de la position de changement de vitesse qui est efficace entre l'élément de changement de vitesse (3) et l'élément sélecteur (5). L'invention concerne en outre une boîte de vitesses à plusieurs vitesses dotée d'un dispositif de changement de vitesse à rail de sélection correspondant.
