SHIFT MECHANISM FOR A VEHICLE GEARBOX

摘要

A shift mechanism for a vehicle gearbox, in particular for a shift gearbox of an agricultural or commercial vehicle that is spaced away from the vehicle gearbox and is connected with the vehicle gearbox by shifter rods or shifter cables. The shift mechanism contains at least one shift lever supported in bearings in a housing so as to pivot and is used to shift gear ratios. The shift lever engagement region located in the interior of the housing engages transfer elements supported in bearings so as to slide parallel to each other and is forced by a reset mechanism into a neutral position. At least one shifter rod or at least one shifter cable connected to the vehicle gearbox is fastened to each transfer element. In order to exclude any risks to safety that could occur by the unintentional engagement of a gear ratio during maintenance or repair operations it is proposed that the shift lever, while in its neutral position interacts by its engagement region simultaneously with at least two transfer elements whereby a relative movement of the transfer elements with respect to each other and thereby the engagement of a gear ratio is prevented.
