Disclosed herein is a combined clutch and brake comprising a drive assembly including a driving member rotatable about an axis and a driving disk fixedly extending on the driving member for common rotation therewith and against axial movement therebetween, a driven assembly mounted on the drive assembly for relative rotation therebetween and against axial movement of the driven assembly, a ring member located in encircling relation to the driving member between the disk and the driven assembly and including an upper surface having an annular friction pad including a radially inner portion in facing relation to the disk and a radially outer portion, a spring biasing the ring axially towards the disk for driving engagement by the disk with the inner portion of the friction pad, a brake member fixed against rotary movement and movable axially between a retracted position and a braking position engaged with the outer portion of the friction pad so as to disengage the ring from the disk against the action of the spring and so as to prevent rotation of the ring, and a coupling connecting the ring and the driven assembly for common rotation thereof and for relative axial movement therebetween, which coupling comprising one or more studs extending from the ring in parallel relation to the rotary axis in the direction away from the disk, and in radially outward relation from the spring and a corresponding one or more fingers extending fixedly from the driven assembly and including apertures receiving the studs to afford common rotary movement therewith and relative axial movement therebetween.
