Gearshifting device for a transmission
The invention relates to a gearshifting device (1), which is intended for a transmission and comprises a selector lever (2) that can be moved in such a manner that different shift positions (P, R, N, D, S, M+, M) can be selected in at least two gearshift gates (3, 4) and that it is possible to shift between one of the gearshift gates (3, 4) and the at least one other gearshift gate (4, 3), and comprises at least one lock (5), which is used to block the traversing path of the selector lever (2) with respect to one of the gearshift gates (3, 4), in order to shift from one of the shift positions (P, R, N, D, S) into another of the shift positions (P, R, N, D, S). According to the invention, at least one locking element (10) is provided, which is mechanically coupled to the selector lever (2) and by means of which the shift lock (5) can be activated and/or deactivated in that with respect to the gearshift gate (3) that is to be blocked, the locking element (10) can be moved into and out of the traversing path of the selector lever (2).
WORK VEHICLE
Work vehicle includes an operation lever pivoting forward and backward stepwise through a plurality of operation positions; and a detent type retention mechanism holding the operation lever in each of the operation positions. The retention mechanism includes a coupling member coupled to the operation lever; and a retention member holding the operation lever via the coupling member. The operation lever and the retention mechanism are provided separately from each other, aligned in a direction intersecting with a pivot support shaft of the operation lever. The operation lever and the coupling member are reciprocally connected via a linking mechanism.
