Definitions

  • the invention relates to a switching unit.
  • the switching unit has a switching element with a Rastierkontur and a shift lock for securing the position of the switching element with a housing and a locking element, wherein the locking element is biased by a spring against the Rastierkontur.
  • Generic switching units are used in particular in transmissions of motor vehicles to set switchable or movable elements in a defined position can.
  • Such a shift lock is known from DE 41 03 465 C2. It has two sleeve-shaped elements which are arranged coaxially with each other.
  • the one sleeve-shaped part is designed as a carrier element which serves a bore for receiving the other sleeve-shaped part serving as a latching element.
  • the latching element can be moved relative to the carrier element in the axial direction, since the receiving bore in the support element and the cylindrical outer periphery of the latching element form a sliding guide.
  • the latching element carries at the end remote from the carrier element a ball which can engage in a recess in a component for the purpose of latching.
  • the locking element is biased relative to the carrier element by a coil spring.
  • a generic switching unit is apparent from DE 10 2005 053 542 A1. To ensure that the shift lock moves only in the region of the Rastierkontur on the switching element and no inadmissible relative movements are possible, the switching element of this switching unit stops for the housing of the lock on. Although the attacks exclude an excessive axial displacement, but must be worked out of the material of the switching element or connected to this inseparable. In both cases, this means an increased production cost. Object of the invention
  • the present invention is therefore an object of the invention to provide a switching unit, which has a simple to manufacture safety mechanism for limiting the linear displacement and / or angular displacement, hereinafter summarized under relative movement having.
  • the object is achieved by a switching unit according to claim 1.
  • the maximum possible stroke of the latching element is matched to the latching contour of the switching element such that a departure from the latching contour is reliably prevented.
  • a separate stop on or on the switching element which cooperates, for example, with the housing of Heidelbergarretmaschine, so that is not required.
  • the production of the works is not necessary.
  • the production of the switching element of a tube or a flat profile is simplified.
  • the Rastierkontur on a profile which is provided at the Heidelbergend- positions with locking recesses If the shift lock from the shift end position is not moved back to the neutral gate, but beyond the shift end point, then the locking element is acted upon by the locking contour so strongly that the stroke limiting device abuts a stop and prevents further movement.
  • the shift lock on a Hubbegrenzungsmittel is not formed by the spring itself, so that it is not forced to "block” and thus is not overloaded.
  • the Hubbegrenzungsstoff is the locking element itself or directly acted upon by the locking element component of Heidelbergarret mich.
  • the stroke limitation means cooperates with a stop which forms part of the shift lock or of the shift lock receiving component.
  • the stop is formed by a part of the housing of the shift lock, for example its bottom or an inwardly projecting projection in its wall.
  • the Hubbegrenzungsmittel prevents according to the invention too strong compression of the locking element.
  • the mounting of the locking element on the housing does not necessarily ensure.
  • the shift lock on a locking element in the form of a ball which is mounted in a dome of a liftable with the ball locking bolt. Rear of the ball, the locking bolt on a neck, which serves as a stroke limiting means.
  • the approach is so long that he after the predetermined by the type of Rastierkontur, maximum allowable deflection on the housing of Wegret réelle strikes.
  • the locking element is held captive.
  • the pot wall is for example cup-shaped, with the pot wall being narrowed or constricted. It can also be the pot edge tapers or the pot bottom opposite, free pot end partially covered by a portion of the housing.
  • the spring can be supported on the opposite end of the pot bottom, the locking element is arranged.
  • the pot wall may be formed as a cylinder jacket or composed of piecewise planar extending pot wall sections. Alternatively, it consists of several spaced apart individual segments.
  • the bottom of the pot is not necessarily flat.
  • the locking element may be formed as a hollow or solid sphere. It can also be designed as a cylinder. Alternatively, it is a sleeve or other, possibly rounded, spring-loaded component.
  • the spring is a spring element which biases the locking element against the housing without the action of external forces. A force applied to the locking element from the outside shifts it towards the bottom of the pot.
  • the spring is preferably designed as a mechanical spring, in particular a helical compression spring.
  • the invention has housing on its pot wall on a stop.
  • the stop protrudes from the pot wall and thus projects laterally inwardly out of the pot wall extending essentially in the compression direction of the catch element. It is understood by lateral protrusion every lead. In particular, no right angle is required to form a stop.
  • the stop can be designed as a material thickening or have the same thickness as the pot wall.
  • the pot wall may be provided with inwardly directed exemptions.
  • the entire housing is pot-shaped and integrally formed.
  • the housing is produced from sheet metal by forming technology. It may be deep drawn, and the stop for the stroke limiting means may be formed by one or more flaps facing away from the pot wall.
  • the lock on its bottom of the pot has a central opening which is formed as a passage and tuned to the winding radius of the helical compression spring. If the opening has an inwardly facing edge, the spring is held securely.
  • the switching element is designed as a shift rod, a shift shaft or a shift rail.
  • the Rastierkontur is either introduced into the shift shaft, for example, by cutting Abhub or it is connected as separately manufactured from the switching element component with this. For this purpose, it can be arranged on a switching sleeve enclosing the switching element or fixed on the switching element as a sheet-metal forming part.
  • the Rastierkontur can be formed by a plurality of substantially mutually parallel and orthogonal to the direction of movement of the shift rail grooves, which can optionally be in the same manufacturing step as the switching element, for example by punching produced.
  • the groove depth of at least the outer grooves with respect to the contour pointing away from the Rastierkontur contour is greater than the remaining stroke, which can perform the locking element in the installed state.
  • the individual grooves are separated by bumps that are smaller than the remaining stroke, so that the shift lock can be moved into each groove.
  • the Rastierkontur may be formed in particular in switching shafts as switching elements by a plurality of circumferential detent recesses in the form of annular grooves.
  • the Rastierkontur no radial rotation is possible by the Rastierkontur.
  • the Rastierkontur only single, trough-shaped locking recesses, which can also form a backup against unwanted movement in the circumferential direction.
  • the Rastierkontur covers only a partial angle range of the switching element.
  • the switching unit has a shift fork, which is arranged on the switching element.
  • the shift lock is firmly connected to the shift fork, so that a movement of the shift fork on the shift element causes a shutdown of the Rastierkontur.
  • the shift fork is connected via a guide tube to the switching element.
  • the guide tube can have a radially oriented extension, for example in the form of a flange, on or in which the shift lock is arranged. It is particularly easy to press this in it.
  • a switching unit in which the functions locking and twisting and disassembly safety instead of several components by the shift lock alone causes.
  • the shift lock can therefore not be turned off or moved by the Rastierkontur without external securing means, so that always a defined positioning of the shift fork in the transmission is possible.

  • the shift lock 4 is biased against a Rastierkontur 3, which is incorporated in the switching element 2.
  • the Rastierkontur 3 has three successive in the switching direction locking recesses 8, in which the locking element 5 can latch. At the respective outer locking recesses 8, in each case a latching edge 21 connects, which merges into the outer diameter of the shift rod, without forming an outer diameter of the shift rod superior bead.
  • the shift lock 4 is firmly connected to a shift fork 13.

  • a latching element 5 is held captive in the form of a ball in each case.
  • the ball is acted upon and biased by a trained as a helical compression spring spring 6.
