TLDR
In this article, a synchronizer assembly for a manual transmission is described, including a shiftable clutch sleeve that is engageable with at least one spring element secured to the synchronizer blocker ring.Abstract:
A synchronizer clutch assembly for a manual transmission comprising a synchronizer hub carried by a torque delivery shaft and including a cone clutch member carried by a gear forming a part of the transmission gearing and a synchronizer blocker ring adapted to be made of forged steel, the synchronizer assembly including a shiftable clutch sleeve that is engageable with at least one spring element secured to the synchronizer blocker ring whereby the blocker ring cone clutch frictionally engages the cone clutch of the gear upon movement of the sleeve toward an engagement position until the rotary motion of the gear is brought into synchronism with the rotary motion of the shaft.read more

Strut-type synchronizer mechanism with retracting and centering strut
TL;DR: In this paper, a strut-type synchronizer mechanism with a leaf spring member adapted for retracting and centering the blocker ring is presented. But the spring member is not a spring, but a leaf-spring disposed within guide slots formed in the clutch hub and which is compressed between the strut and the strut.
Patent
Inertia lock type synchronous clutch mechanism
Sadanori Nishimura,Satoru Kudo +1 more
TL;DR: In this article, an inertia lock type synchronous clutch mechanism was proposed, in which elastic ring members on blocking rings were engaged by a shift sleeve splined to a clutch hub at a plurality of sloping circumferential cam portions protruding from the inner circumference of the sleeve so that the blocking rings are moved axially into frictional engagement with tapered cone portions of synchronized gears.

Hydraulically-actuated shift system for a transfer case
TL;DR: In this article, a hydraulic-actuated shift system was proposed for shifting a mechanical shift apparatus of a power transfer device between first and second operative positions. But it is not suitable for use with four-wheel drive transfer cases for permitting the vehicle operator to shift between two-wheel and fourwheel drive modes.
