FIELD: engines and pumps. ^ SUBSTANCE: magnetic clutches containing a casing and a rotor are used to drive the cable drums, the clutch casing being attached to the drum. The magnetic clutch rpm is produced by the reduction gear, the cable unwinding resulting from tension caused by the electrically-driven vehicle. ^ EFFECT: significant speed of the vehicle incorporating the cable drum, swift change over from forward to reverse motion, invariable cable tension and longer life of the cable drum motor. ^ 3 cl, 3 dwg |
