Definitions

  • the invention relates to a ball catch for securing adjustment positions of an axially and / or pivotally movable actuating element - in particular a shift linkage for manual transmissions of motor vehicles - the components being accommodated in a sealed housing - into which the ball detent housing is screwed and sealed from the outside and wherein the detent ball is guided indirectly or directly in the ball detent housing.
  • Such ball catches are known for example from GB 2 089 451 A or DE-GM 86 30 656.1.
  • a suit is carried out in such a way that a collar is attached, on which a surface is brought into contact with a corresponding sealing surface of the housing.
  • the invention has for its object to provide a ball catch whose housing is designed so that no separate seals or sealing measures are required to ensure a tight fit in the housing. This object is achieved in that the ball catch housing screwed into the housing consists of plastic.
  • the design of the ball catch housing made of plastic results in such pressure when screwing in that overall a tightness is achieved without the need for any special sealing measures.
  • the ball catch housing can have a conical threaded section. As a result, the pretensioning force is increased to improve the tightness within the thread.
  • a further embodiment of the invention provides that the ball detent housing has a collar, on the surface of which is opposite the sealing surface of the housing, a circumferential sealing lip is formed.
  • the sealing lip is installed in a depression in the surface and protrudes from the surface of the surface in the unassembled state.
  • the arrangement of the sealing lip in the depression ensures that no over-tightening of the seal can occur. As soon as the tightening required for a tight fitting of the sealing lip to the sealing surface of the housing has been reached, the entire surface of the collar comes into contact with the sealing surface. Another tightening is no longer possible.
  • the sealing lip is arranged so that it runs towards the longitudinal axis of the ball detent housing, that is, directed inwards. In this way it is achieved that even if liquid: could still escape from the housing via the thread of the ball catch housing, under the pressure the sealing lip is increasingly brought into contact with the sealing surface of the housing and thus causes a hermetic seal .
  • the ball detent housing is then provided on its threaded portion with a shoulder which is designed on its ring edge as a sealing lip which, when screwed in, is in contact with the bore step of the housing.
  • Polyamide is proposed as the preferred material for the ball catch housing.
  • FIG. 1 shows an installation of the ball catch in a shift transmission
  • Figure 2 is a side view of Figure 1 and
  • Figure 3 shows the ball catch as a separate component in longitudinal section.
  • the shift rod 2 is arranged in bearings in the axial direction, that is to say along the axis 3 and in the initial direction — that is to say pivotably about the axis 3.
  • the shift rod 2 is assigned one or more shift elements 4 which engage in a shift fork 5 for moving the same.
  • this or the switching element 4 is provided with a corresponding latching recess 6.
  • the catch ball 8 of a ball catch 7 arranged in a stationary manner in the housing 1 engages in this.
  • the ball catch 7 has a ball catch housing 12 which is screwed into a threaded bore 9 of the housing 1.
  • the threaded bore 9 is based on a bore step 11.
  • the bore step 11 adjoins the sealing surface 10 of the housing 1.
  • the ball catch 7 is shown as a single part.
  • the ball catch housing 12 is made of plastic, in particular polyamide PA66-GF. It has a bore 13 in which a metallic bush 14 having a bottom is inserted. In this sleeve 14, the locking ball 8 is guided. The locking ball 8 is acted upon by a spring 15, which is supported on the locking ball 8 by a slider 16.
  • the ball catch housing 12 has a threaded section 17 that matches the threaded bore 9 of the housing 1. This is followed by a shoulder 23 away from the locking ball 8, which merges into a collar 18.
  • the collar 18! is on its outer circumference key surfaces 19 for screwing the ball catch 7 into the housing 1.
  • the sealing surface 10 of the housing 1 is opposite the surface 20 of the collar 18.
  • the shoulder 23 can also be formed on its peripheral edge as a sealing lip 24.

Abstract

Un dispositif de retenue à bille (7) sert au maintien de positions de réglage d'un élément de réglage mobile axialement et/ou de manière pivotante, en particulier d'une tringlerie de commande de changement de vitesse pour les boîtes de vitesses de véhicules automobiles. Les éléments sont disposés dans un carter étanche (1) de la boîte de vitesses, dans lequel le boîtier (12) du dispositif de retenue est vissé, étanché de l'extérieur, la bille d'arrêt (8) étant guidée directement ou indirectement dans ledit boîtier (12). Le boîtier (12) est conçu de telle sorte qu'il ne faut pas avoir recours à des joints ou à des mesures d'étanchéification séparés pour garantir une assise étanche dans le carter (1). A cet effet, le boîtier (12) vissé dans le carter (1) est en plastique.
