Adjustment device for activating, deactivating running, friction and coupling rollers and clamp rails has rotatable eccentric device that can be driven by actuator in form of vacuum cell

摘要

The adjustment device (2) varies the position of a wheel or rail by means of an eccentric device (12) that can be rotated relative to its axle, which is fixed to the chassis, and that can be driven by an actuator in the form of a vacuum cell (6). The vacuum cell and the eccentric device can be attached to a common bearer. The eccentric element is connected by a cable to a movable rod of the vacuum cell. An independent claim is also included for the following: (a) an adjustment drive.
