Abstract: A shoe mounts an outer spring defining a longitudinal direction and an inner spring arranged within the outer spring. The outer and inner springs define corresponding end sides of the outer and inner springs, and the shoe defines an end side of the shoe. A spring-position limitation limits the outer spring in its longitudinal direction and enables the inner spring to emerge at the end side of the shoe out of the outer spring. A driver primary element exerts a pressure on the inner spring as the driver approaches the outer and inner springs in a direction of the corresponding end sides of the outer and inner springs.

A separator sheet includes a ring element. At least one sliding block extends from the ring element between adjacent spring elements and is arranged circumferentially about the spring elements. The primary element has also an inner part having an external toothing, an outer part on which the primary dog is arranged and having an internal toothing engaging into the external toothing, and at least one damping part arranged between the external and internal toothing for vibration damping between the inner and outer parts.
