An accessory drive for attachment to the end of a shaft. The drive comprises a belt pulley, a carrier with at least a first and a second planet wheel that are strongly coupled and which have differing numbers of teeth, the first planet wheel being in engagement with a first gear circulating along with the shaft, and the second planet wheel with a second gear that is rotatable relative to the shaft, an activatable and deactivatable brake being provided between a continuously stationary part and a part capable of relative rotation, and a freewheel to prevent backward relative rotation of the second gear with respect to the end of the shaft. The first and second gears are arranged radially inside the carrier, such that the freewheel is arranged between the carrier and the part capable of relative rotation and the belt pulley at least partially surrounds the freewheel, the carrier, and the brake radially and externally, and so that the belt pulley and carrier are joined in rotary engagement.

An accessory drive for attachment to the end of a shaft, comprising: a belt pulley; a torsion spring; a carrier that is joined in rotary engangement with the belt pulley via the torsion spring; at least a first and second planet wheel in association with the carrier, said first and second planet wheels being rigidly connected to one another and being of dissimilar diameter; a first gear circulating along with the shaft, wherein the first planet wheel is in engagement with the first gear; a second gear that is rotatable relative to the shaft, wherein the second planet wheel is in engagement with the second gear, wherein said first and second gears are arranged radially inside the carrier; a selectively activatable brake located between a permanently stationary part and a part capable of relative rotation; and a freewheel to prevent backward relative rotation of the carrier with respect to the sleeve; wherein the freewheel is arranged between the carrier and the part capable of relative rotation, and the belt pulley at least partially surrounds the freewheel, the carrier, and the brake radially and externally.
