Title: Gear selection control for transmission
Inventor: PETZOLD RAINER
IPC: F15B15/28
Filed: 1997-12-19
Abstract: A fixed ratio transmission has each gear selected by a compact selector system driven by a pneumatic/hydraulic servo with the selector fork (2A) attached directly to the servo piston.  The servo and selector fork are mounted on a guide rail (9) and an inductive displacement monitor (3) provides accurate data on the position and movement of the servo.
