  • Patent number: 5788036
    Abstract: A synchronizing arrangement for a gear transmission includes a synchronizing ring and the surrounding annular spring, the ring having at least three equally spaced support elements at the circumference of the ring at which the spring is snugly supported with a press-fit about the ring. The support elements and the spring define opposing contact surfaces which are relatively adjustable upon assembly of the annular spring about the ring in order to balance manufacturing tolerances.

  • Patent number: 5343993
    Abstract: In a synchronizing device for transmission assemblies, a gear shaft includes a detent mounted thereon in a twist-proof manner and at least one speed wheel cooperating with the detent and rotatable on the gear shaft by movement of a sliding sleeve. A clutch is connected in a shape-locking manner to the speed wheel and a synchronizing ring enabling engagable and disengagable friction coupling of the clutch with the detent. The synchronizing ring including a conically-shaped coupling surface and the friction coupling including a friction ring body subassembly with a conical friction surface having a sintered-on friction lining and cams, and is connected in a shape-locking manner by the cams to the clutch and interacts by means of the friction lining with the conical coupling surface.
