ABSTRACT:
The friction clutch includes a device for taking up clearance comprising a ramp device disposed circumferentially and adapted to be rotated by a toothing which they carry at their periphery and with which cooperates a worm disposed tangentially: the worm is mounted so as to slide along its axis while being subject to the action of a so-called taking-up elastic spring and it is when it is moved along its axis that it rotates ramps; the load of the taking-up spring increasing with the wear on the linings the axial movement is obtained when the load is sufficiently high to overcome the axial force due to the return device to which the ramps are subject, with the clutch released; driving of the worm in rotation is provided and made operational by the wear on the friction linings when the clutch is engaged; non-return devices prevent the worm from turning in the direction opposite that in which it is driven by the driving devices.
