Quick-action clamping nut for clamping the rim of a vehicle wheel on an externally threaded end of a shaft of a balancing machine

摘要

A speed clamping nut to clamp the rim of a vehicle wheel on an end fitted with an outer thread of a shaft of a balancing machine, comprising a housing having at least one grip mounted in substantially radially manner to the housing, and an inside thread. A threaded component rotational about the screw axis of the speed clamping nut and relative to the housing is connected to the housing and comprises an inside thread and is connected with the drive side of a rotational drive system connected to the housing. Following engagement, the rotational drive system assumes the complex and time-consuming screwing-on procedure when the wheel rim is pulled against spring forces toward a centering cone.
