Abstract
A shifting device of a transmission comprises a selector interlock which can prevent a gear shift shaft from moving into an outer shift gate. The interlock comprises a locking ring which is axially and rotationally movably supported by the shaft. The ring has a stop surface with a tooth and a locking surface and is held by a spring in a rest position. A stop surface of the shaft abuts the tooth when the shaft is moved toward the outer shift gate, before reaching the second inner shift gate. The locking surface of the ring abuts a housing locking surface when the shaft reaches the next shift gate by further displacement of the shaft. The tooth of the ring engages in a recess when the shaft ring rotates to a gear shift position in the next inner shift gate.
