Abrégé

A compact clutch including a driven shaft on which the following are mounted: a gear wheel; a driving bush; a driven bush; a coil spring; a first collar with cam surfaces; and a second collar with cam surfaces. The gear wheel and the bushes are arranged axially next to each other; the gear wheel and the driving bush are constrained together in the circumferential direction; the spring surrounds externally the bushes; the first collar surrounds externally the spring; and the second collar surrounds externally the first collar. The gear wheel and the bushes are constrained to the driven shaft in the axial direction by means of two stop rings; and the driven bush is constrained to the driven shaft in the circumferential direction by means of at least one tongue.

A compact clutch which comprises a driven shaft on which the following are mounted: a gear wheel; a driving bush; a driven bush; a coil spring; a first collar with cam surfaces; and a second collar with cam surfaces. The clutch is characterized in that the gear wheel and the bushes are constrained to the driven shaft in the axial direction by means of two stop rings; in that the driven bush is constrained to the driven shaft in the circumferential direction by means of at least one tongue; and in that the tongue ensures engagement between the driven bush and the driven shaft in the circumferential direction, while in the axial direction the driven bush may slide with respect to the driven shaft.

A transmission device includes a drive shaft and two driven shafts. The drive shaft is connected to a wheel and first engagement rotors are arranged therebeside so that the wheel is located therebetween and can rotate together with them. The first engagement rotors having an axial hole in which a driven shaft is rotatably arranged, the first engagement rotors are coupled or uncoupled with second engagement rotors coaxially arranged therebeside, by extracting or retracting, respectively, at least one mobile tooth rotatable in a seat of the first engagement rotors, each driven shaft being keyed to a second engagement rotor. Driving rotors are arranged around the driven shafts between the wheel and the first engagement rotors and are provided with a brake, so that relative rotation of the driving rotors with respect to the first engagement rotors causes extension or retraction of the mobile tooth according to the relative rotation direction.

Abrégé

Device suitable for transmitting a torque from a drive shaft (4) to two driven shafts (6, 6'), wherein the drive shaft (4) is mechanically connected to a wheel (8) and first engagement rotors (12, 12') are coaxially arranged beside the wheel (8) so that the wheel (8) is located between these rotors (12, 12') and can rotate together with them, wherein the first engagement rotors (12, 12') are provided with an axial hole in which a driven shaft (6, 6') is rotatably arranged, wherein the first engagement rotors (12, 12') can be mechanically coupled or uncoupled with second engagement rotors (13, 13') coaxially arranged beside the first engagement rotors (12, 12'), by extracting or retracting, respectively, at least one mobile tooth (14) which can rotate in a seat made in the first engagement rotors (12, 12'), each driven shaft (6, 6') being keyed to a second engagement rotor (13, 13'), wherein driving rotors (18, 18') are coaxially and rotatably arranged around the driven shafts (6, 6') between the wheel (8) and the first engagement rotors (12, 12') and are provided with braking means (19, 19'), so that the relative rotation of the driving rotors (18, 18') with respect to the first engagement rotors (12, 12') causes the extension or the retraction of the mobile tooth (14) of the first engagement rotors (12, 12') according to the direction of this relative rotation.
