Switching and locking device for .Yochael gearbox

The ßrfAnäung concerns a timing and locking device for motor vehicles, in which eggs üan ^ wechoel through a threatening and shiftable switching » pipe that carries the ttobal.t forks; Switching and Verriegolunßnvorriohtunaen are known, their 30Imit and detachment elements on one single rotating and sliding sohaltwelle sit while sHatliohe UchnltgKbeln durohseteen · The arrangement of the switching and Vtsrriegelun & selemente'is chosen so that according to the Pre-selection control of the holding shaft a switching element forta-Dchlücsig connected to the holding fork to be operated and the rest of the takeaway while keeping the long on the holding forks held by the Verrie {* elun {; eeleaients glide through

The disadvantage here is that if all switching and locking elements are arranged on a Sohaltwelle, the longitudinal nut on distributed in the bores of the Sohalt forks on the circumference must be attached, whereby the holding forks are not can be carried out uniformly, which makes warehousing easier and the interchangeability of the holding forks is difficult

The object of the invention is basically to provide a holding and locking device based on the aforementioned holding device from uniform holding forks au sohaffen, at which the switching * and unlocking elements fully in that of:. | den laben umeohlo | i * n * n Rau »lie · X - ^.;
