Pendulum power transmission drive wheel with mechanical
recovery of part of the braking energy, developed from a
reducer (3) attached to the vehicle suspension. The
drive wheel (1) is fixed to the slow shaft (4) of the
reducer (3). On the fast shaft (5) on its
stub axle, a bearing (7) is fixed from which a swing arm (6) hangs, at the end of which the engine (8) is fixed, which drives the fast shaft (5) by means of a belt transmission (11), chain or gears, forming a
pendulum assembly (19). On the arm (6)
brake calipers (14) are mounted which, when activated on the disc (13), keep the
pendulum assembly (19) raised, by the effect of the engine
brake (8), accumulating
potential energy. To move the vehicle, the
calipers (14) are deactivated and the engine (8) is started simultaneously, recovering part of the braking energy on its descent and facilitating the starting of the engine (8) and the vehicle.
