摘要： The invention relates to a disengagement system (32) for a vehicle (10) with a first shaft (22) and a second shaft (24). The disengagement system (32) includes a housing (34), an input shaft (36), a pinion shaft (38) and a coupling device (40) for selectively coupling the input shaft (36) to the pinion shaft (38). The coupling device (40) includes a coupler (66) and an actuator (68) connected to the coupler (66). The actuator (68) is configured to slide the coupler (66), so that the coupler (66) couples to and transmits a driving force between the input shaft (36) and the pinion shaft (38) in an engaged position of the coupling device (40) and uncouples from the input shaft (36) and the pinion shaft (38) in a disengaged position of the coupling device (40).

摘要： The invention relates to an epicyclic reducer for a vehicle hub that includes: a housing; a sun gear arranged in the housing that includes sun teeth and is configured for coupling to an input; a plurality of planet gears, each of which includes planet teeth meshed with some of the sun teeth; a planet carrier that couples the planet gears to each other and is configured as an output; and a ring gear that includes ring teeth meshed with some of the planet teeth of each of the planet gears. The ring gear can be moved within the housing between a reduction position in which the planet gears are configured to rotate relative to the ring gear, and a direct drive position in which the ring gear is constrained to rotate with the planet gears.

摘要： The invention relates to a wheel hub (30) that includes a housing (32) and a reduction system (34). The reduction system (34) includes a planetary gearbox (48) configured to be operably connected between the axle (36) and the wheel (26), a sleeve (50) configured to slidably connect to the axle (36), and an actuation device (52) connected to the sleeve (50) and configured to slide the sleeve (50). The reduction system (34) has a first operating position in which the sleeve (50) engages with the planetary gearbox (48) to transmit the driving force from the axle (36) at a speed reduction ratio, and a second operating position in which the sleeve (50) disengages from the planetary gearbox (48) in order to cease transmitting the driving force from the axle (36) so as to freely rotate the wheel (26).

摘要： The present invention relates to a novel braking system for vehicles, such as those suitable for transporting loads and/or passengers, that is made up of features capable of substantially reducing the structural complexity of these braking systems, particularly of those models provided with dual actuation, and thereby reducing the costs involved in the manufacturing and assembly of the braking systems and the vehicles themselves. More particularly, the system of the present invention comprises an armature (1) fixed to the rigid axle (E) of the vehicle (V), on which a drum (2) is placed, which is associated with the wheel hub (R), at least two shoes (3) provided with brake linings (30) being arranged on diametrically opposite edges of said armature (1) and moving towards the inner surface of said drum (2) by means of a drive assembly (4) that is made up of a first actuator (5a) positioned adjacent to one end of said shoes (3), and a second actuator (5b) positioned adjacent to the opposite end of said shoes (3), at least one of which is coupled to an actuator assembly (9) of the vehicle (V); it also comprises supports (7a, 7b) that are mounted concentrically with the respective actuators (5a, 5b) and interconnected by means of rods (8) arranged at the ends thereof.

摘要： The invention relates to a wheel hub (30) that includes a housing (32) and a reduction system (34). The reduction system (34) includes a planetary gearbox (48) configured to be operably connected between the axle (36) and the wheel (26), a bushing (50) for slidably connecting to the axle (36), and an actuation device (52) for sliding the bushing (50). The reduction system (34) has a first operating position in which the bushing (50) engages with the planetary gearbox (48) to transmit driving force from the axle (36) at a first speed ratio, and a second operating position in which the bushing (50) disengages from the planetary gearbox (48) and engages with the end cap (44) of the housing (32) in order to transmit driving force from the axle (36) at a second speed ratio that is 1:1.

摘要： The present invention relates to a wheel drive assembly for application in a vehicle, such as for example those provided with hybrid drive systems, the features of which have been designed and developed to allow the simplified, low cost installation of an electric motor individually on the wheel assembly of a vehicle. The present invention relates more particularly to a wheel drive assembly that comprises an electric motor (8) mounted on a casing (7) inside which is arranged a transmission assembly made up of a primary drive shaft (9) that is associated, on one side, with the power output of said electric motor (8) and, on the other side, with a secondary drive shaft (10) that has a toothed end (101) arranged so that it interacts with a ring gear (11) fixed to the wheel hub (4) of the wheel assembly (S).
