Definitions

  • the present invention relates to a shift lever arrangement for a transmission of a motor vehicle according to the preamble of claim 1.
  • Such a shift lever arrangement is known from DE-OS 2 057 311.
  • a shift lever which is displaceable under spring preload is provided in a bearing element.
  • the shift lever dips into the frame against the force of the spring.
  • the counterforce exerted on the shift lever by the spring increases with increasing immersion depth.
  • rapid and resistance-free immersion of the shift lever is no longer possible, particularly in the event of a severe impact on the shift button. Injuries can still occur.
  • the object of the present invention is to mitigate the impact of the body or a part of the body on the switch button of the shift lever to such an extent that injuries or at least serious injuries can no longer occur even in the event of a strong impact.
  • the bearing element is slidably received in a corresponding opening in a frame and is held by a holding means, the holding means being designed such that it breaks the switching lever when a predetermined axial load is exceeded, so that the bearing element in can dip the breakthrough. - If the specified axial load is exceeded due to an impact, the shift lever dips into the frame quickly and without resistance. This reduces the risk of at least serious injuries.
  • the frame can be the vehicle body. But it is also possible that the frame forms a separate part, which e.g. is used near the center console of the body.
  • the holding means can advantageously have at least one pin projecting radially from the bearing element.
  • the pin can be provided in a corresponding one on the opening
  • the recess can be provided both on the inner peripheral surface of the opening and on the upper peripheral edge thereof.
  • the pin and, if necessary, the predetermined breaking webs are dimensioned such that they break off in the event of an impact and the gear lever together with the gear knob disappears in the frame, so that there is no further risk of injury from the gear knob.
  • 1 is a schematic cross-sectional view of a first shift lever arrangement
  • 2 shows the shift lever arrangement according to FIG. 1 in the immersed state
  • FIG. 5 is a schematic cross-sectional view of a third shift lever arrangement
  • FIG. 6 is a plan view of FIG. 6,
  • FIG. 9 is a plan view of FIG. 8,
  • FIG. 10 is a schematic cross-sectional view of a first embodiment of a pin
  • FIG. 11 is a schematic cross-sectional view of a second embodiment of a pin
  • Fig. 12 is a schematic cross-sectional view of a third embodiment of a pin and
  • FIG. 13 is a schematic cross-sectional view of a fourth embodiment of a pin.
  • the frame 1 with a housing or a frame for holding a shift lever arrangement is designated, which in the area of Dashboards of a motor vehicle is arranged.
  • the frame 1 has an opening or an opening 2, for example a bore, a slot or the like.
  • a bearing element or a bearing bush 3 is slidably mounted.
  • the bearing bush " 3 is secured against displacement and rotation by laterally projecting pins 4 by engaging in the associated recesses or recesses 5 of the frame 1.
  • the arrangement or the breaking resistance of the pins 4 is selected such that they collide with a vehicle occupant in the event of an impact break off before there is a greater possibility of injury.
  • a shift lever 6 is pivotally mounted by means of a ball 7.
  • the shift button 8 provided on the shift lever 6 projects in the direction of the passenger compartment.
  • a switching arm 9 is arranged laterally projecting on the switching lever 6.
  • the shift arm 9 is non-positively connected to a gearbox, not shown, of a motor vehicle.
  • the shift arm 9 can be attached to the shift lever 6 via predetermined breaking bars 10. These break off when the pins 4 have already broken off and the shift lever 6 has slipped a little forward. Then a part of the shift rod 9 hits a frame part, the predetermined breaking webs 10 be overloaded and also cancel. The shift lever 6 is therefore no longer in operative connection with the transmission. Only then, as already described above, the shift lever 6 plunges further into the frame 1.
  • the predetermined breaking webs 10 are advantageously fastened on the one hand to a stop part 11 of the switching arm 9 and on the other hand directly or indirectly on the switching lever 6.
  • the stop part 11 is favorably tapered towards the frame 1 in such a way that the tapered end 11.1 has a smaller diameter 11.2 or a smaller cross section than the diameter 2.1 or the cross section of the opening 2 of the frame 1.
  • the diameter or cross section of the rest Section of the stop part 11 is larger than the diameter 2.1 or the cross section of the opening 2, so that the stop part 11 can only partially dip into the opening 2.
  • the bearing bush 3 is provided in a separate bearing 12.
  • the bearing 12 is displaceable in the opening 2 of the frame 1, but is fixed in its position by attached to it, laterally projecting pins 13 which engage in recesses 5 of the frame 1.
  • the bearing 12 has a support flange 12.1 for the bearing bush 3.
  • the breaking strength of the pin 13 is chosen as that of the pin 4 of the bearing bush 3 according to FIGS. 1 and 2.
  • the support flange 12.1 of the bearing 12 can optionally be omitted.
  • the bearing bush 3 is here in the bearing 12 by means of pins 4 attached to the bearing bush 3 in corresponding recesses 12.2 of the bearing 12. This gives you an additional predetermined breaking point.
  • a plurality of predetermined breaking webs 10 are advantageously provided one behind the other in the direction of the longitudinal axis 6.1 of the shift lever 6.
  • two predetermined breaking webs 10 are provided one behind the other.
  • predetermined breaking webs 10 are present in one plane, these are preferably arranged opposite one another, as shown in FIGS. 1 and 2. Preferably, if there are more than two predetermined breaking bars in one plane, they are arranged in a star shape. When using a funnel-shaped stop part 11, the length of the predetermined breaking webs 10 is expediently greater with increasing distance from the frame 1 (cf. FIGS. 1 and 2).
  • the pins 4 rest on an upper peripheral edge UO of the opening 2.
  • D is the thickness of the frame 1.
  • the locking lugs 14 are arranged radially offset to the pin 4 for simplification of manufacturing.
  • the bearing element 3 is expediently made in one piece from injection-molded plastic.
  • the pins 4 extend into recesses 5 which are half-open at the upper peripheral edge UO.
  • the latching lugs 14 engage in further recesses 15 at the lower peripheral edge UU which are likewise half-open. This is how the bearing element is secured against rotation and displacement
  • the pin 4 can be designed as a spring tongue inclined in the direction of the latching lug 14 to compensate for tolerances in the thickness D of the opening 2.
  • a concentric depression 16 can also be provided in the vicinity of the upper peripheral edge UO.
  • a retaining ring 17 can be provided according to FIG. 11, which can be fixed on the frame 1. In this case, the thickness of the pins 4 is selected so that they are held in a clamped manner in the concentric depression 16 when the retaining ring 17 is fixed.
  • knobs or ribs can be provided to ensure a clamping attachment according to FIG. 12 on an upper side of the pins facing the shift lever 6. 13, it is also possible to make the top side convex. A concave design of the top is also conceivable.
  • a torsion-proof attachment can of course also be achieved with the retaining ring 17 if the pins 4 rest on the upper peripheral edge UO of the opening 2.
  • the retaining ring 17 can have recesses corresponding to the pins 4. The depth of such Recesses are less than the thickness of the pin to ensure a clamping hold.

Abstract

L'invention concerne un ensemble levier de changement de vitesse pour une boîte de vitesses d'un véhicule à moteur. Un levier de changement de vitesse (6), qui fait saillie dans le compartiment passager, est monté pivotant dans un élément de support (3). Pour réduire le risque de blessure en cas d'impact contre la tête (8) du levier de changement de vitesse (6), il est prévu, selon l'invention, que l'élément de support (3) soit logé, de façon à pouvoir être déplacé, dans une ouverture (2) correspondante d'un châssis (1) et soit maintenu par un moyen de retenue (4) qui est conçu de façon à se casser lorsqu'une charge axiale prédéterminée s'exerçant sur le levier de changement de vitesse (6) est dépassée, ce qui permet à l'élément de support (3) de s'enfoncer dans l'ouverture (2).
