The driving wheels of the prior art have damping elements that work essentially in compression. A viscoelastic material working in compression is able to transmit a higher load, and therefore a higher actuator torque.
However, the ability of the material to dissipate vibrational energy is much poorer than when the material is working in shear. Conversely, the transmission of shear load is limited by the risks of the material failing (by tearing).
Also known, from document DE 196 18 635, is an elastic transmission coupling for a sewing machine comprising an elastic element equipped with a cylindrical exterior profile with a groove for collaborating with a first shaft and an exterior profile shaped to collaborate with a second shaft that has a bore with internal teeth. Hence, mechanical power can be transferred from the first shaft to the second.
Also known, from document U.S. Pat. No. 1,780,727, is a power transmission device for a motor vehicle. The transmission device is of the type involving obstacles consisting of teeth between which an elastic material designed to damp out jerkiness is located.
