ABSTRACT:
A shifting mechanism for a motor vehicle transmission comprises first and second stationary pivots transversely spaced apart. A range shifting fork is pivotally movable about said first pivot to a plurality of range control positions, which include a slow range position, a fast range position, and a no-load position. An axle shifting fork is pivotally movable about said second pivot to a plurality of clutch control positions, which include a clutch-engaging position and a clutch-disengaging position. A bridge extends transversely to the shifting paths and has one end portion connected to the range shifting fork and a second end portion connected to the axle shifting fork. A first pivotal joint is spaced from said first pivot and pivotally connects said first end portion of said bridge to said range shifting fork. A second pivotal joint is spaced from said second pivot and pivotally connects said second end portion of said bridge to said clutch control fork. A manually operable selector lever is movable along said bridge to positions near said first and second pivotal joints, respectively, and transversely to the longitudinal direction of said bridge. Coupling means connect said lever to said bridge and are adapted to impart to said bridge a pivotal movement about each of said pivotal joints in response to a movement of said lever in the direction which is transverse to the longitudinal direction of said bridge when said lever is in a position near the other of said pivotal joints.
