Abstract: “BELT TENSIONER WITH HIGH DAMPING RUBBER DEVICE”, the present invention refers to the technical field of belt tensioners in general, more specifically a belt tensioner (1) with high damping and with a rubber device (2), designed to generate higher rigidity and high damping to belts in combustion engines. The object of the tensioner is to reduce manufacturing costs, wearing and noise, both of the tensioner itself and the belt.

Abstract: The present invention refers to the technical field of starting impeller devices in general, more specifically a cage with integrated springs as applied to a torque transmission system and free wheel with rollers as applied to starter drives in starting devices and similar. The invention presents, as a novelty, a cage (1) with integrated springs (1A) made in one single part of plastic, steel or other material, which has been especially developed to reduce the quantity of parts, facilitate the assembly and reduce the costs of the final product.

Abstract: “PROCESS TO MANUFACTURE SHAFT AND GUIDE PINS AS USED FOR PLANETARY SYSTEMS”, the present invention refers to the technical field of automotive parts, more specifically to a process to manufacture a shaft (1) and guide pins (2) as used for planetary systems, which purpose is to improve the strength, durability and to reduce the costs of final products.
