provides on spindle (1) of a rotary joint.subject to a retention effect of elastic counterclockwise from helical spring (2) is set in a cylindrical body (3) of the fixed part carried by a stirrup (4) of a parallelograma closed frame (5) made by the structure of frame of the stroller.a linear piastriforme support (6) disposed on a transverse of said parallelogram frame (5) on its lower terminal based on fixings (7).on the one hand a group of electric motor (1) with the shaft (9) passing through a hole (10) of said support (6), and then on the other side of said support, a traction roller (11).for the non intervention, the motor device is held to a superior limit excursion to arrest allowed by a pin (12) of the linear debordo support (6).to prepare the device motor use contested the group motor (8) is initially in lifting and.for subsequent rotation counterclockwise of the stirrup (12) opposed by the spring booster (16), the delivery together with the pin (12) of the support (6) so, linearbraking impulse thrust of the helical spring (2), it is accompanied in lower reach the roller traction (11) on the underlying wheel
