<p>A synchronizer (10)(e.g. pin-type double acting) with friction rings (22,36 and 24,38), jaw members (30,26,28), blocker means (e.g. three circumferentially spaced pins (40) including blocker shoulders) for preventing asynchronous engagement of the jaw members (30,26,28), means (e.g. pre-energizing assemblies (42) responding to initial movement of a shift flange (32)) for enabling initial engagement of the friction rings (22,36 and 24,38) and blocking means, and self energizing means (e.g. cams (20e,20f,32f,32g)) producing an additive force (Fa)(e.g. in response to either of the cams (32f,32g) moving a link (60) radially inward against either of the cams (20e,20f)), there being force limiting means for limiting the additive force (Fa) including resilient means (66) positioned to act radially. <IMAGE></p> |
