Definitions

  • the invention relates to a shift rail of a motor vehicle transmission, which is formed at least from a flat profile, and at least one formed on the flat profile engagement element and on which the engagement element is integrally formed from the material of the flat profile.
  • the shift rails are formed from flat profile.
  • the flat profile has less square, but usually rectangular cross-sections.
  • the longer sides in the rectangular cross-section are usually the edges and describe the height of the side surfaces of the flat profile.
  • the length of the side surfaces is determined by the length along the flat profile.
  • the shorter sides describe the distances between the outer edges of the side surfaces of the flat profile directed transversely to the vertical axes and thus the short distances of the edge surfaces of the flat profile.
  • the edge surfaces are often perpendicular or obliquely to the side surfaces extending cut surfaces between the outer edges of the side surfaces, which arise when punching the flat profile, for example, from sheets.
  • the outer edges of the side surfaces are then the cut edges of the flat profile.
  • the edge surfaces or cut surfaces often limit outside attack elements that protrude rectified from the flat profile with the vertical axes - or deepening are introduced into the flat profile.
  • the projecting engagement elements are bounded laterally byassinabschnit- the side surfaces and formed like a switch finger. Part of these attack elements are also bent or bent from the actual course of the flat profile deviating from this after stamping and are thus at least partially laterally from the flat profile.
  • the attack elements which are introduced deepening in the flat profile, with the vertical axes rectified depressions in the flat profile. Examples of such attack elements are GmbH bugs, which are also called in DE 102 05 033 A1 Heidelbergnuten.
  • attack elements Possible combinations of protruding and recessed introduced attack elements are, for example, the locking contours of locking devices, which are also shown in DE 102 05 033 A1 and engage in the so-called locking pin of locking elements resiliently biased.
  • Other attack elements are edges of through holes that are stamped into the flat profile and run against the stops or attack which shift finger.
  • attack elements described above are, since they rectified projecting with the tall axes simply introduced when punching the flat profiles of sheets or strips.
  • the punching tools only have the negative shape of the outer contour of the cut edge thus also the outer contour of the side surfaces of the engagement elements.
  • Attack elements laterally beyond the shift rail are formed by bending or, as initially described, by tapping off. However, these attack elements are only edge of the shift rail and are not feasible for reasons of space in any case.
  • the object of the invention is therefore to provide shift rails and internal circuits of manual transmissions, which can be produced easier and cheaper.
  • the (empty) volume of the recess corresponds to the volume of the portion of material protruding from the flat profile. This proportion is from the flat profile by embossing or punching plastically displaced material. The depression is formed during embossing and penetration by displacing the material to form the protruding portion.
  • the inventive design of the shift rail makes it possible to easily integrate functional elements such as stops, Heidelbergbauuler and shift finger and thus cost in the punching process for the production of the shift rail.
  • the shift rails are then manufactured in one operation with tools that punch and emboss or punch through or punch. When punching, the material is cut at the edges.
  • embossing material When embossing material is essentially displaced from the flat profile to form a three-dimensional profile at one or more points from the profile and accumulated at other points targeted.
  • the clumps are formed into the protruding engagement element.
  • material having a high level of plastic deformation When passing through, material having a high level of plastic deformation is pulled, for example, into cup-like projections without interruption of the fibers of the material.
  • punching the material is partially cut without complete separation and moved with a small amount of plastic deformation, without the cohesion of the protruding part is offset with the flat profile.
  • Mixed forms of the aforementioned methods are also conceivable.
  • the invention facilitates the production of shift rails with attack elements projecting vertically or obliquely to the vertical axes of the profile, such as shift fingers, shift mouths or stops, or engagement elements which are designed to be at least switch finger, switch mouth or stop.
  • attack elements projecting vertically or obliquely to the vertical axes of the profile
  • shift fingers, shift mouths or stops, or engagement elements which are designed to be at least switch finger, switch mouth or stop.
  • FIG. 1 shows an overall view of an inner circuit consisting of a ner central selector shaft and a shift rail
  • FIG. 2 shows the plan view of the inner circuit according to FIG. 1,
  • FIG. 3 the detail Z from FIG. 2, greatly enlarged and not to scale
  • FIG. 4 shows a section of the flat profile of the shift rail from the inner circuit according to FIGS. 1 and 2,
  • Figure 6 shows an alternative design of a flat profile with the features of the invention to a shift rail not shown.
  • Figures 1 and 2 show an inner circuit 1 of a vehicle transmission not shown.
  • the inner circuit 1 is formed of a central shift shaft 2 and a plurality of shift rails, of which only one shift rail 3 is shown for a gear.
  • the central control shaft 2 is formed by the actual shaft 4 and by a multifunctional actuator 5.
  • the multifunctional actuating element 5 has a plurality of engagement elements 6 of the most varied design and a very wide variety of functions.
  • the shift rail 3 has linear bearings 2, 3 for longitudinally displaceable mounting in a housing, not shown, of the vehicle transmission.
  • the shift rail 3 is provided with attack elements 7 according to the invention.
  • the engagement elements are laterally, ie perpendicular or alternatively also obliquely to the vertical edges H, from the side surface 11 of the two side surfaces 11 and 12 from the flat profile 10 of the shift rail 3 (FIG. 4).
  • the edges H determine together with the shorter edges K the cross section of the flat profile 10.
  • the short edges K describe the width of the edge surface 16 which connects the side surfaces 11 and 12 to form the flat profile 10 together.
  • One of the engaging elements 6 on the actuating element 5 is a switching jaw 8 (FIG. 3).
  • One of the attack elements 7 of the shift rail is a shift finger 9, which intervenes temporarily in the shift jaw 8.
  • the positive engagement of both elements 6 and 7 is shown in FIG.
  • At least one portion 14 of the material of the flat profile partially protrudes from the flat profile 10 on the engagement elements 7 and is connected to the flat profile 10 in one piece.
  • the protruding part is e.g. formed on the portion 14 is followed at the back of a recess 15 in the flat profile.
  • the recess 15 is circumferentially surrounded by the material of the flat profile 10 and open to the side surface 12 of the flat profile 10.
  • the volume bounded in the recess 15 corresponds to the volume of the portion of material of the flat profile 10 which protrudes from the flat profile 10, since the recess 15 in this case was produced by punching and displacing material 14.
  • FIG. 6 shows an alternative embodiment of engagement elements.
  • the engagement elements 7 are each formed by a portion 17 which protrudes from the edge surface 16 of the flat profile 10.
  • the recess 18 following the portion 17 is open both towards the side surface 12 and towards the edge surface 19.
  • the attack elements are not laterally, but rectified with the vertical axis of the edge surface 16 out.
  • two of the engagement elements 7 are limit switches 21 as a shift jaw 20.
  • Another of the engagement elements 7 is a stop 21, which also has an embossed detent contour 22 on the end face.
