Inertia speed synchronizer

Claim 1

An inertia speed synchronizer, comprising: a coupling consisting of a disk part and a splined part; holes made in said disk part of the coupling; interlocking faces made on said disk part adjacent said holes; pins passing through said holes, each of said pins having interlocking faces sunk into the body of said pin, and contacting said interlocking faces of said disk of the coupling at the moment of synchronization; a ring fixed at the ends of said pins and having a conical face for interacting with the conical face of the mating component of the gear-box; a springy element having contact sections located aside of said disk of the coupling, and resting on said pins; slots made in said pins on the side of contact with said springy element; fixing side surfaces limiting said slot along the Pin, and serving to interact with said contact sections of said springy element, said fixing surfaces being located between said interlocking face of the pin and said ring with a conical face disposed in the direction of movement of said coupling, said synchronizer being a double-acting synchronizer, the springy element comprising two spring rings mounted on either side of the disk of said coupling, and spaced apart a distance equaling the length of their traverse across the bottom of the slot, the depth of the latter being taken approximately equal to the depth of the latter being taken approximately equal to the depth of the interlocking faces of the pin.
