The cable for the accurate transmission of longitudinal motion is comprised of a tubular envelope (7) formed by an external sheath (1) and by metal cables (2) concentric to an internal rolling envelope (3) and a central core (N) provided with an axial reinforcement consisting of a metal cable (4), whose core (N) may slide and rotate on itself inside the tubular envelope (T). The core (N) configures longitudinally radial protuberances (5) which define equidistant serrated grooves (6), a wire (7) being helically wound around the core (N) and defining in each serrated groove (6) longitudinally contiguous compartments (9) wherein is housed a bowl (10) which, upon sliding of core (N) with respect to the tubular envelop (7), may roll along said compartment (9). Application to the car industry. <IMAGE> |
