Abstract
A shifting device (1) for pinion gear change transmissions which actuates the positive fit couplings by selector forks (3, 21) that slide on a stationary longitudinal guide (2). Shifting forces are transmitted from the shifting finger (9) to the selector forks (3, 21) by profiled metal plates (4, 5, 6) suspended in the selector fork (3, 21), the other end of the plates is guided in a switching comb (7) and the automatic locking device for blocking non-shifted gates and gears and gear selection is actuated via the locking plates (11) and sliders (16). The configuration of the inventive shifting device (1) makes it possible to provide a reliable, simple, low-costing shifting device suitable for various types of shifting mechanism such as lever shifts, turning-shaft shifts, cable and hydrostatic shifting mechanisms and automation modules.
