Abstract: The invention provides, in one aspect, a lubrication system for internal combustion engines of the kind comprising a crankshaft (1) and an associated oil sump (3), a camshaft in a cylinder head above the oil sump, and a timing belt (5) connecting the crankshaft and camshaft via respective, pulleys (2, 4). In accordance with the invention, the timing belt is adapted to entrain a sufficient quantity of oil from the oil sump to lift it to the cylinder head for lubricating purposes, thereby eliminating the need for a separate oil pump. Preferably, an oil pulley (7) is provided below the crankshaft pulley (2) positioned to be immersed in oil within the oil sump for entraining oil therefrom. In one form, in which the crankshaft and camshaft pulleys (2, 4) have similarly formed tooth sets of different diameters to effect the timing required, the timing belt (5) is of an impermeable material over its width and is formed with a set of teeth (6) around its inner face meshing with said toothed pulleys, the oil pulley also has a tooth set (8), and the timing belt has an additional set of teeth (9) extending around its outer face for meshing with the teeth of the oil pulley, said outer teeth providing the means for entraining oil to the cylinder head. In another aspect of the invention, an engine lubrication system is provided wherein a toothed pulley (2 or 4), is provided, the teeth (32, 36) of which run over a part of their rotation in a restricted passage provided by a casing (10) and a belt (5) having mating teeth also runs for part of its movement in a restricted passage provided by said casing, these runs being guided to a meeting point (33, 35) at which oil under pressure is available as a result of meshing action of the two sets of teeth.

Abstract: A transmission system is provided that has a drive pulley, at least one driven pulley and an oil wet toothed belt. The toothed belt includes a toothing and a back, a first portion, wherein the toothing is coupled to the drive pulley, a second portion wherein the toothing is coupled to at least one driven pulley, a first taut branch which develops towards the driving pulley and a second slack branch which develops towards the driven pulley. The transmission system also includes a fixed containment guide having at least a first wall facing the toothing and/or the back positioned at a distance from the toothed belt between a minimum distance where at rest it is not in contact with the toothed belt and a maximum distance equal to 5% of the length of one between the taut branch and the slack branch.

Abstract: A power transmission mechanism (10) having a V-belt (11) provided with transverse reinforcing elements (22). The V-belt, in the illustrated embodiment, defines a cog belt wherein the reinforcing elements are disposed within the cogs (15) thereof to have opposite end surfaces (23) exposed at the side edge surfaces (21) of the belt. A thin film of lubricating fluid (27) is provided on the exposed end surfaces of the reinforcing elements for improved long troublefree operation of the mechanism. Different structures for providing the thin film of lubricating fluid are disclosed. In the illustrated embodiments, the thin film extends along the entire side edge surfaces of the V-belt.
