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.

A fluid operated disconnect coupling comprising first and second power train elements mounted for movement relative to each other between a coupled, power transmitting position and a decoupled, nontransmitting position; means connected to at least one of said elements for effecting said relative movement between said positions and comprising a first fluid cylinder; fluid operated latch means for latching said effecting means in at least one of said two positions including first and second mating latch parts, said second latch part being carried by said effecting means and said first latch part being movable for latchingly engaging or releasing said effecting means by latchingly engaging or releasing said second latch part, a second fluid cylinder for moving said first latch part and a valve operable with said first latch part to establish fluid communication between said fluid cylinders when said first latch part has released said effecting means; and control means for selectively directing fluid under pressure to said second cylinder.
