Abstract
A shifting device ( ) for pinion gear change transmissions which actuates the positive fit couplings by selector forks ( ) that slide on a stationary longitudinal guide ( ). Shifting forces are transmitted from the shifting finger ( ) to the selector forks ( ) by profiled metal plates ( ) suspended in the selector fork ( ), the other end of the plates is guided in a switching comb ( ) and the automatic locking device for blocking non-shifted gates and gears and gear selection is actuated via the locking plates ( ) and sliders ( ). The configuration of the inventive shifting device ( ) 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.
