ABSTRACT:
A transmission with built-in brake, particularly for vehicles, comprising an oil bath inside a containment and supporting casing, an epicyclic reduction unit kinematically connected to a power unit by means of at least two gears, of which the driven gear is axially fixed, coaxial to the sun gear and associated therewith by means of a splined coupling. A disk brake is arranged between the epicyclic reduction unit and the driven gear, so that at least one first disk is rigidly coupled to an internally-toothed ring gear rigidly coupled to the casing and so that at least one second disk is rigidly coupled so as to rotate together with the driven gear. The disk brake is associated with pusher means for packing that can move axially. Moreover, the pusher means comprise a flange, the piston of a fluid-activated actuator integrated in the casing acting on the flange. A pivot is rigidly coupled to the flange and protrudes from the casing. Respective actuation means act on the actuator and on the pivot.
