A reducer (10) having :
- a central electric motor (20);
- two wheel hubs ((MZ1)(MZ2)); each hub ((MZ1)(MZ2)) having a respective epicyclic reduction gear ((RR1)(RR2));
- a differential assembly (30); and
- a brake assembly (40). The central electric motor (20) separates the differential assembly (30) from the brake assembly (40). And the brake assembly (40) in turn has :
- an instantaneous brake piston (42);
- a first set (43) of outer disks integral with a box ((BX2));
- a second set (44) of inner disks integral with a sleeve (45); the second set (44) of disks alternating with the first set (43) of disks;
- a third set (46) of disks integral with the sun gear ((SN2)) of the epicyclic reduction gear ((RR2));
- a fourth set (47) of disks projecting inwards of the sleeve (45) and alternating with the third set (46) of disks; and
-a stop (48) integral with the box ((BX2)). |
