Abstract
Mechanisms and methods for clamping force generation are disclosed. In one embodiment, a clamping force generator includes a spring coupled to a traction ring and to a load cam roller cage. The traction ring can be provided with a recess to receive the spring. In some embodiments, a relatively short spring is provided. In other embodiments, a spring couples to a wire and the spring-wire combination couples to the traction ring and the load cam roller cage. In some embodiments, the load cam roller cage is provided with tabs adapted to engage the wire and/or the spring. In yet other embodiments, the traction ring is configured to receive a dowel pin for coupling to the spring. One or more of the tabs can include a tab notch that cooperates with a stop pin coupled to the traction ring to provide adjustment of the travel of the load cam roller cage.
