PCT No. PCT/EP87/00557 Sec. 371 Date Mar. 28, 1990 Sec. 102(e) Date Mar. 28, 1990 PCT Filed Sep. 29, 1987 PCT Pub. No. WO88/02450 PCT Pub. Date Apr. 7, 1988.A drive wheel with a friction brake having a circulating coolant in which feeding and draining take place in a non-rotational axle pipe (1) and the ring-gear carrier (2), attached thereto, without the heated coolant flowing through a planetary transmission (19, 20) supported between a half-shaft (14) and a ring gear (13). The collant enters radially beneath the brake discs (11, 12), retained by a brake-disc carrier (15), into an collecting annular space (27) and is thrown outwardly by centrifugal force between the brake discs (11, 12). It is returned to a cooler, situated outside the area of the transmission, by a coolant drain pipe (24) in the external hub collar (7) of the ring-gear carrier (2). By providing different seals (5.1; 17.1; 17.2; 15.1) at the connecting points of the brake and the transmission, the mixing of the brake coolant with the transmission lubricant is prevented. By this arrangement the transmission and the brake, together with the ring-gear carrier (2), can be dismounted from the axle pipe (1) as complete unit despite the connections without the need to dismount the wheel or jack up the vehicle.
