Abstract: In an aspect a device for a driven shaft is provided that receives an input torque that varies cyclically between a peak input torque and a low input torque at a peak input torque frequency, which includes a shaft adapter, a rotary drive member, at least one isolation member, a torsional vibration damping structure including an inertia member and a elastomeric damping member, and a supplemental damping structure. The supplemental damping structure applies a supplemental damping torque to resist relative movement between the rotary drive member and the inertia member in addition to damping provided by the elastomeric damping member. A sum of torques including the supplemental damping torque limits a maximum twist between a first end of the driven shaft and a second end of the driven shaft, to below a yield point of the driven shaft.

The treads are generally disposed radially around the main body and extend distally from outer portion of the main body. The main body generally defines a plurality of compression cells and may present a substantially frustoconical outer surface.

Abstract: A rubber-sprung wheel for rail vehicles includes a wheel tire which is connected to a wheel rim by a rubber insert that is formed by two flat rings that are arranged so as to be essentially vertical in relation to a wheel axle. The two flat rings are held, under considerable axial prestress, between an inner circumferential middle web of the wheel tire and two outer flanges of the wheel rim. At least one of the flanges is seated on the wheel rim with an interference fit that is designed as a conical press fit, such that a cone of the flange in a stress-free state has a lesser conicity than does a cone of the wheel rim, and in a pressed-on state rests on an entire surface against the cone of the wheel rim, at an even surface pressure across an entire width of the interference fit.

Each segment has a T-shaped metal member the T-stem of which is generally trapezoidal in shape and is vulcanized-bonded to a rubber block similar in shape which has an opposite surface vulcanized-bonded to a thin sheet metal segment. Each rim segment assembly is separately connected by suitable means to the hub member. A protective device guarding against tire collapse in event of failure of a bond between the rubber block and a metal member, engages the T-stem and hub member.
