    摘要: A pin-type, double-acting synchronizer mechanism (10) with friction clutches (26, 46 and 28, 48), jaw clutches (34d, 30a and 36d, 32a) and improved self-energizing ramps (70a-70d and 72a-72d). Three circumferentially spaced pins (50) include blocker shoulders for preventing asynchronous engagement of the jaw clutches and pre-energizer surfaces which each cooperate with a pre-energizer assembly (52). The self-energizing ramps act between a shaft (12) and a shift flange (42) which is rotatable relative to the shaft and jaw clutch members (34d, 36d). Flange (42) includes radially inwardly extending teeth (72) defining the self-energizing ramps (72a, 72d) which act against the self-energizing ramps (70a, 70d) defined by a post like portion (70) formed from shaft splines (13).

    摘要: A pin-type, double-acting synchronizer mechanism (18) with friction clutches (20,32 and 22,34), jaw clutches (24,14b and 26,16b) and self-energizing ramps. The ramps act between a shaft (12) and a shift flange (28) which is rotatable relative to the shaft and jaw clutch members (24,26). Flange (28) includes radially inwardly extending teeth (48) defining self-energizing ramps (48a,48b,48c,48d) which act against ramps (50a,50b,50c,50d) defined by a post-like portion (50) formed from shaft splines (12b). Three circumferentially spaced pins (36) include blocker shoulders for preventing asynchronous engagement of the jaw clutches and pre-energizer surfaces which each cooperate with a pre-energizer assembly (38). Friction members (20,22) of the friction clutches are slidably splined to gears to prevent relative rotation therebetween and abut surfaces (14d,16d) defined by gears (14,16) to limit axial movement away from mating friction rings (32,34), respectively. Axial movement toward the mating friction rings is limited by rigid pins (44) slidably extending through openings (32b,34b) in the rings.

    摘要: The invention proposes a device using friction in a liquid medium having a support, notably metallic, on which an interface surface forms a support for a friction lining, with a flat annular shape overall, produced from a friction material which has a porous structure with communicating cells and which has areas (M1, M2, M3) with different controlled porosities. The method of manufacturing the friction lining including a step of moulding under pressure, whilst the interface surface of the support has at least one groove in which there extends the friction material moulded under pressure in order to constitute an area of controlled porosity (M1, M2) greater than the mean porosity (M2, M3) of the body made from friction material constituting the lining.

    摘要: A baulkring-type synchronizer (18) for frictionally synchronizing and positive connecting gears (14,16) to a shaft (12). The synchronizer includes a plurality of tabs (54,56) with self-energizing ramps (54a,54b and 56a,56b) which react synchronizing torque to self-energizing ramps defined by an axially slidable shift sleeve (34) secured against rotation relative to the shaft. Synchronizing is provided by cone clutch surfaces (24,48) and (26,50) which are engaged by an operator shift force (F.sub.o) and an additive force (F.sub.a), which forces are both applied to the cone clutch surfaces via angled blocker teeth surfaces (36a,44a and 36b,46a).
