Abstract
A four-wheel drive toy vehicle having a spring-wound motor capable of travelling over hills and other obstacles. The vehicle is provided with front and rear traction wheel sets whose axles extend across the chassis which support the body. Each axle has a pinion thereon which engages the front section of a two-section coupling gear that meshes with the input gear of a flat spiral spring motor whose output gear engages the rear section of the coupling gear. The input gear is coupled to the input of the spring through a one-way clutch whereby when the vehicle is grasped by the player and pulled back along the ground, the input gear is caused to turn by both pinions to thereby wind up the spring; and when the vehicle is released, the output gear which is turned by the unwinding spring then acts to drive both pinions to advance the vehicle in the foward direction. One of the pinions is coupled by a gear train to a governor which acts to regulate the speed of wheel rotation.
