Definitions

  • the invention relates to a sheet-metal shifting arm for transmitting shifting movements.
  • Shifting arms of this type are arranged fixedly on shifting elements, such as shifting shafts or shifting forks.
  • the shifting shafts sit displaceably and/or pivotably in the transmission.
  • the shifting forks sit, for example, displaceably and/or pivotably on a shifting rail.
  • the shifting elements are displaced and/or pivoted by means of a shifting finger or an actuating element of similar design.
  • the actuating element engages in a shifting mouth or cutout of similar design on the shifting arm and transmits shifting movements to the shifting element.
  • Locking cylinders or the like also frequently engage in the shifting mouth and prevent gear-shifting errors.
  • the shifting arms are, as a rule, punched parts.
  • the stop faces for the shifting fingers lie, as a rule, opposite each other in the shifting mouth of a shifting arm. Their distance from each other and alignment with respect to each other have to be realized with very high accuracy. Similarly, very exacting requirements are placed on the dimensional accuracy of other, further functional faces in the shifting mouth, for example functional faces for the engagement of a locking cylinder.
  • the required accuracies for the functional dimensions such as for the distance between the stop faces lying opposite each other in the shifting mouth, and functional faces, such as for the chamfers, which bound the shifting mouth and are required for the gentle introduction of the shifting finger into the shifting mouth, and roundings on body edges, can, as a rule, only be obtained by a material-removing finishing operation.
  • Some functional faces are too rough for a frictional contact with the shifting finger due to the punching outline along the cut edge of the parts after punching has taken place, and therefore also have to be finished with a material-removing operation.
  • FR 27 62 659 shows a shifting arm of the generic type.
  • a shifting arm produced from metal plate is fastened to a shifting fork.
  • This shifting arm has a shifting mouth.
  • the wall of the shifting arm is reinforced in the region of the shifting mouth in order to provide stop faces of sufficient width.
  • the shifting arm being a formed part which is formed from a thin sheet without cutting the sheet.
  • the advantages of a shifting arm according to the invention in comparison with the prior art reside in the low costs for production, particularly in large-series and mass production.
  • the consumption of material for the production of a shifting arm of this type is low.
  • the weight of this shifting arm is reduced by up to 50% in comparison with the shifting arms described at the beginning.
  • the thin material permits virtually unlimited designs. Use is made of forming processes without cutting, in particular processes for the cold-forming of sheets, such as rolling, drawing, stamping and punching.
  • the required accuracies for functional dimensions such as for the distance of the stop faces lying opposite each other in the shifting mouth, and functional faces, such as for the positioning and dimensioning of chamfers and roundings for the gentle introduction of the shifting finger in the shifting mouth, is, as a rule, obtainable only by the forming process or forming processes. Material-removing machining is unnecessary, as a rule.
  • Sheets having a thickness of the starting material of up to 2 mm in limit cases of up to 2.5 mm are preferably used for the production of the shifting arms according to the invention.
  • Sheets of St35, Ck45, C35 and low-alloy deep-drawing steels, such as 16MnCr5, and all weldable and further formable steels and deep-drawing steels can be used as the material.
  • the shifting arms are preferably fastened by welding to shifting elements, such as shifting rods and shifting forks.
  • the shifting arms according to the invention are subjected to edge-layer hardening in the region of the switching mouth by means of induction hardening processes. It is also conceivable, for cost reasons, to harden the entire shifting arm or the shifting arm welded to the shifting element as one unit. In this case, case-hardening processes or through-hardening processes can be used, depending in each case on the type of steel used.
  • the object of the invention is furthermore achieved by the shifting arm being a formed part which is formed from a thin sheet without cutting and has a recess open in the shape of a mouth toward one edge of the shifting arm, for the engagement of a shifting finger.
  • the recess is used to provide the shifting mouth on the shifting arm for the engagement of the shifting finger.
  • the shifting mouth is provided, for example, by a cutting-out step in a multi-stage forming process or by punching followed by stamping or protrusion of the edges of the shifting mouth.
  • stop faces for the switching finger are provided with the edges of the recess being protruded or by them being stamped.
  • the sheet at the edges of the recess is preferably protruded in such a manner that the sheet is angled from or out of the plane of the actual flat base body of the shifting arm, generally at right angles, but also at any other desired angle, and as far as possible forms an edge hemming the entire recess.
  • the width of the edge is determined by the required width of the stop faces, which are subsequently stamped onto the edge or produced by means of sizing, and/or also as a function of the demands placed on the stiffness of the shifting arm.
  • the stop faces for the shifting finger lie, as a rule, opposite each other in the shifting mouth. Their distance from each other and alignment with respect to each other have to be realized with very high accuracy. Similarly, very exacting demands are placed on the dimensional accuracy of other functional faces in the shifting mouth, for example functional faces to rest a locking cylinder against. These accuracies for the functional dimensions, such as for the distance of the stop faces lying opposite each other in the shifting mouth from each other and their alignment with respect to each other, can be ensured, as a rule, without a material-removing finishing operation.
  • the recess to be bounded at least by two stop faces, which lie plane-parallel opposite each other, face each other and are formed without cutting, on angled sections of the sheet, the distance between the stop faces lying opposite each other being realized, by machining without cutting, with an accuracy which permits a deviation from the desired value of the distance of at maximum ⁇ fraction (1/10) ⁇ mm.
  • Functional faces such as the stop faces and such as the chamfers, which bound the shifting mouth or the stop faces and are required for the gentle introduction of the shifting finger into the shifting mouth, and roundings on body edges, are introduced without cutting.
  • the surface of these functional faces is smooth and work-hardened on account of the stampings or the sizing. The resistance to wear of the faces is increased. Material-removing polishing is unnecessary.
  • a further refinement of the invention makes provision for the recess to be bounded at least by two stop faces, which lie opposite each other, face each other and are formed without cutting, on angled sections of the sheet.
  • the shifting arm has at least one body edge which delimits the stop face at least at one side to form a further lateral face of the shifting arm and has a chamfer formed on it without cutting.
  • a distance describing the chamfer in the cross section of the shifting arm between an edge, which bounds the stop face towards the chamfer, and an imaginary cut edge has an accuracy which permits a deviation from the desired value of the distance of at maximum ⁇ fraction (1/10) ⁇ mm.
  • the imaginary cut edge is a common cut edge, which is parallel to the edge, of the stop face, which is extended beyond the chamfer, together with the further lateral face of the shifting arm, which face is extended beyond the chamfer.
  • the distance of the edge, which separates the stop face from the face produced by the chamfer, from the corner point of an imaginary, unbroken body edge is therefore very precise and can be realized more precisely than the distance brought about by material-removing machining.
  • the object is furthermore achieved by the shifting arm being a formed part which is formed without cutting from a thin sheet, the formed part being designed in a fork-shaped manner at one end and in this case being provided at the end with two prong-shaped projections.
  • the shifting arm also has at least one edge on its outer contour that is formed by an angled sheet.
  • Each of the projections is provided, on a section which is angled from the sheet of the shifting arm, at least with a stop face which lies opposite a further stop face lying opposite on the other of the projections.
  • a shifting arm of this type can be produced with a great saving on material and has a low weight.
  • the design possibilities are diverse.
  • the shifting arm prefferably has at least one tab which is angled from the shifting arm, and for the shifting arm to be connected to a shifting element by means of at least one weld on the tab.
  • the tab is fastened to the shifting element by suitable welding processes, such as laser welding, resistance welding or inert-gas arc welding.
  • the shifting arm is provided with at least one formation of bead-like design.
  • the shifting arm is provided on the different wall sections in a manner corresponding to its purpose with one or more beads or with laminations, stampings, protrusions of the sheet or bending over of the sheet at the edges, which are produced without cutting.
  • an edge which is peripherally reinforced as far as possible on the shifting arm which is essentially of flat design. This reinforced edge is produced by a bead or by a sheet which is angled away at the edge from the flat base body.
  • the invention makes provision, in particular for higher loads, for the shifting arm to be a bracket-shaped formed part which is formed without cutting from a thin sheet.
  • the shifting arm has a first wall section with a recess open in the shape of a mouth toward one edge of the shifting arm, for the engagement of a shifting finger.
  • the recess is bounded at least by two sections, which lie opposite each other and face each other and are formed without cutting, on angled sections of the sheet.
  • the first wall section merges integrally into three further wall sections which are angled from the first wall section and facing the same direction.
  • a refinement of the invention makes further provision in this respect for the further three wall sections of the shifting arm also to be formed integrally with one another.
  • the shifting arm is therefore formed by a deep-drawn part of shell-shaped design.
  • the shifting arm is provided on at least one or individual or all of the different wall sections in accordance with its use with one or more beads or with laminations, stampings, protrusions of the sheet or bending over of the sheet at the edges, which are produced without cutting.
