PCT No. PCT/EP81/00059 Sec. 371 Date Feb. 23, 1982 Sec. 102(e) Date Feb. 23, 1982 PCT Filed May 29, 1981 PCT Pub. No. WO82/00270 PCT Pub. Date Feb. 4, 1982.A drive assembly for a motor vehicle, especially for city buses, consists of a continuously variable transmission (G) and four clutches (31, 32, 33 and 34). The first clutch (31) connects a prime mover (M) to a flywheel (S), the second (32) the flywheel (S) to intermediate gearing (Z), the third (33) the prime mover (M) to a driven shaft (30), and the fourth (34) the intermediate gearing (Z) to the driven shaft (30). To keep the variable transmission (G) as simple as possible it has a differential (D) with three transmission components (21, 22, and 23) and is preferably in the form of a planetary-gear set. The variable transmission (G) is composed of two, preferably hydrostatic units (G1 and G2). The internal geared wheel (23) of the planetary-gear set (D) is preferably connected to the prime mover, its sun wheel (21) with one hydrostatic unit (G1), and its ring gear (22) with both the intermediate gearing (Z) and the other hydrostatic unit (G2).
