<p>The miniature model car (10; 110; 210) comprises: a transmission system (18) comprising a driving shaft (20), adapted to receive mechanical power from a propulsion engine (16); a rear-wheel assembly (24), which cooperates with the driving shaft (20). The transmission system (18) comprises, furthermore, a pair of rear axle shafts (34), which are connected to the rear-wheel assembly (24); and a pair of one-way couplings (35; 135; 235), each one being suited to kinematically and automatically disconnect a respective rear axle shaft (34) from the driving shaft (20), when the rear axle shaft (34) rotates at a higher speed than the driving shaft (20).</p> |
