Abstract:

Positive retention of a power train coupling in either a coupled or decoupled position is achieved in a structure including first and second power train elements 12 and 14 mounted for movement relative to each other between a coupled power transmitting position and a decoupled non-transmitting position by the provision of a pair of fluid operated latches 34 and 36 engageable with a double acting piston 28 and cylinder 26 which is operable to move one of the elements 12,14 relative to the other. Each latch includes a moveable latch element 48 for latchingly engaging a groove 30, 32 in the rod 24 mounting the pistion 28, a second fluid cylinder 38 for moving the latch element 48, and a valve 52, 54 for establishing fluid communication between the second cylinder 36 and the double acting cylinder 26.
