A device for automatically locking a wheel onto a front end of a balancing machine shaft includes a hollow profiled body provided with a frontal member on which the rim of the wheel to be balanced bears. The profiled body acts as a housing for a slider positioned coaxial to the shaft and extends beyond the bearing member where it presents a threaded portion arranged to receive a ring nut for locking said wheel rim. The housing is intended to be connected to a pressurized fluid source in such a manner that the slider is able to slide between a withdrawn locking position in which the ring nut urges the wheel rim against the bearing member, and an advanced release position in which the ring nut is disengaged from the wheel rim.

[ What is claimed is:] [1.] A locking device mountable on a shaft of a wheel balancing machine for locking a wheel on the shaft, the locking device comprising:a hollow profiled body having an axial direction of extension and including a first open end constructed and arranged to receive a distal end of the shaft of the wheel balancing machine, and a second open end having laterally extending flanged bearing surface against which the wheel is borne;a slider constructed and arranged within said profiled body so as to be selectively moveable along said axial direction of extension, said slider including an elongate portion extending from said second open end of said profiled body, said elongate portion being aligned coaxially with the shaft of the wheel balancing machine and including a threaded distal portion for receiving a cooperatively threaded locking member thereon; anda fluidic pressure supply mechanism constructed and arranged to selectively cause said slider to move within said profiled body between an axially retracted position in which the wheel is urged into abutting said bearing surface by said locking member threaded on said elongate portion, and an axially extended position in which said locking member is moved away from the wheel so as to release the wheel from a position abutting said bearing surface, said fluidic pressure supply mechanism comprising a valve assembly constructed and arranged to selectively feed and exhaust fluidic pressure, said valve assembly being provided at a distal end of said elongate portion of said slider.
