Abstract:
1. An actuating device for vehicle transmissions, in particular of tracked vehicles or wheeled vehicles having a wheel-based steering system, comprising: a remote shifting gate, a pivoting gate, and an emergency shifting gate of a vehicle transmission; a single lever for actuating the remote shifting gate, wherein in the remote shifting gate the single lever is shiftable into a forward driving position, a neutral driving position, and a reverse driving position, wherein the single lever is provided for actuating a pivoting movement in the pivoting gate, and wherein the single lever is provided for actuating the emergency shifting gate, wherein in the emergency shifting gate the single lever is shiftable into a towing position, a forward driving position, a neutral driving position, and a reverse driving position; a switching element included on the single lever; and signal transmission elements associated with the pivoting gate, the remote shifting gate and the emergency shifting gate such that the switching element engages into the signal transmission element associated with the remote shifting gate, which is centrally located between the signal transmission elements associated with the pivoting gate and the emergency shifting gate, in every transverse position of the switching element and such that the switching element in every transverse position produces a driving-direction signal; wherein the signal transmission element associated with the pivoting gate determines a first electric signal from a first mechanical signal of the switching element by a first electric sensor and wherein the first electric signal is transmitted to an electro-hydraulic transmission controller; wherein the signal transmission element associated with the emergency shifting gate transmits a second mechanical signal of the switching element mechanically to a transmission hydraulics; and wherein the signal transmission element associated with the emergency shifting gate determines a second electric signal from the second mechanical signal of the switching element by a second electric sensor and wherein the second electric signal is transmitted to the electro-hydraulic transmission controller.
