Abstract

The device, inserted between a motor (9) and a load (11), allows the load (11) to be immobilized when power is not applied to the motor (9) and allows mechanical torque to be transmitted when power is applied to the motor (9). Such a device is produced by virtue of a juxtaposition of brake disks rotatably connected alternately to the drive shaft (8) and to a casing (10) containing the motor (9) by sliding connections, the end disks (1, 3) of the juxtaposition being rotatably connected on the drive shaft (8) and by virtue of means (4, 5) collaborating to separate these disks and transmit the mechanical torque. The architecture of the device allows the string of dimensions associated with the functional clearance between the means (4, 5) to be reduced and allows the force exerted by the spring (6) on the disk (1) to be reacted by the bearing.
