Definitions
- the present invention relates to a toothed belt and, in particular, a toothed belt for use with oil and to the relative timing control system.
- Toothed belts generally comprise a body of elastomeric material, embedded in which are a plurality of longitudinal filiform resistant inserts, also called “cords", and a plurality of teeth covered by a coating fabric.
- Each component of the belt contributes towards increasing the performances in terms of mechanical resistance, to decrease the risk of breakage of the belt and increase the specific transmissible power.
- the coating fabric of the belts increases the abrasion resistance and hence protects the working surface of the belt from wear which is due to rubbing between the sides and the slopes of the teeth of the belt and the sides and the bottoms of the grooves of the pulley with which the belt interacts.
- the coating fabric decreases the coefficient of friction on the working surface, , reduces deformability of the teeth and above all reinforces the root of the tooth, thereby preventing breakage.
- the coating fabric used may be constituted by a single layer or, alternatively, may be a double layer to guarantee increased toughness and rigidity.
- the coating fabric is normally treated with an adhesive, for . example RFL (resorcinol-formaldehyde latex) to increase adherence between the body and the fabric.
- RFL resorcinol-formaldehyde latex
- U.S. patent US4099422 relates to a toothed belt suitable for use in oil bath and comprising a body in elastomeric material, preferably epichlorohydrin, and a double fabric coating the teeth.
- the patent application EP0549401 relates to a toothed belt comprising a body formed of a first layer made of CSM or ACSM and a second layer on the side of the teeth formed of an HNBR matrix covered by a fabric treated with HNBR.
- a toothed belt comprising a body formed of a first layer made of CSM or ACSM and a second layer on the side of the teeth formed of an HNBR matrix covered by a fabric treated with HNBR.
- none of the prior art toothed belts have a high resistance to wear and generally operation in direct contact with oil facilitates breakage of the belt which therefore has a reduced average life.
- toothed belt to be used with oil or partly immersed in oil is capable of withstanding the duration tests established for use in vehicle drive systems.
- Replacement of chains and gears in existing systems and, therefore, with the overall dimensions already defined, would make it preferable to use toothed belts having a narrower width with respect to the wid ⁇ h of the belts normally used in systems not in direct contact with oil.
- a possible solution could be the use of a material with a much higher modulus than the one used in the toothed belts currently on the market, to form the resistant inserts of the belts, which define the modulus of the belts almost entirely.
- resistant inserts made entirely of carbon fibre could be used.
- the object of the present invention is therefore to obtain a toothed belt which can be used with oil or even partly immersed in oil without decrease in the performances of said belt and maintaining the necessary mechanical properties of adhesion, resistance to wear, precision of meshing and noise emission.
- a further object of the present invention is to allow chains and gears to be replaced without variations in the dimensions of the control system and therefore to use toothed belts of limited width. According to the present invention this object is obtained by a toothed belt as claimed in claim 1.
- a timing control system as claimed in claim 25 is also provided.
- - Figure 1 shows a perspective and partial view of a toothed belt according to the invention
- - Figure 2 shows a diagram of a first timing control system using a first toothed belt according to the present invention
- - Figure 3 shows a diagram of a second timing control system using a second toothed belt according to the present invention
- - Figure 4 shows a diagram of a third timing control system using a third toothed belt according to the present invention
- - Figure 5 shows a schematic and enlarged section of a reinforcing insert for a toothed belt according to the present invention
- - Figure 6 shows a graph of the values of decline in tensile strength of a belt according to the present invention compared with a belt produced according to the known art.
- a toothed belt is indicated as a whole with the number 1.
- the belt 1 comprises a body 2 made of elastomeric material, embedded in which are a plurality of longitudinal filiform resistant inserts 3.
- the body 2 has a first face provided with toothing 4, which is covered in a coating fabric 5, and a second side or back 6 of the belt.
- the back 6 is also covered in a fabric 7.
- the fabric 5 which coats the toothing 4 is the same as the fabric 7 which coats the back 6.
- the body 2 comprises as main elastomer, that is, present for more than 50 weight % with respect to the other elastomers used in the mixture, a copolymer formed from a monomer containing nitrile groups and from a diene.
- the copolymer used is hydrogenated acrylonitrile butadiene.
- the copolymer used is obtained from monomers containing nitrile groups in a percentage between 33 and 49 weight % with respect to the final copolymer.
- the copolymer used is obtained from monomers containing nitrile groups in a percentage of 39 weight % with respect to the final copolymer, for example it is possible to use a mixture constituted by 50% of THERBAN 3446 (Bayer registered trademark) and by 50% of THERBAN 4307 (Bayer registered trademark) .

- each weft thread is constituted by an elastic thread as core and by at least one composite thread wound on the elastic thread, where the composite thread comprises a thread with high thermal ' and mechanical resistance and at least one coating • thread wound on the thread with high thermal and mechanical- resistance.
- a toothed belt 1 according to the present invention comprises a resistant layer 8 disposed externally to the fabric 5.
- an adhesive 9 is also interposed ' between the fabric 5 and the resistant layer 8.
- the resistant layer 8 is constituted by a fluorinated plastomer with the addition of an elastomeric material, the fluorinated plastomer being present in an amount greater in weight with respect to the elastomeric material.
- An example of resistant layer usable is for example described in the patent EP1157813 to the same applicant.
- the fluorinated plastomer is preferably a compound based on polytetrafluoroethylene.

- the resistant layer 8 is also disposed over the fabric 7 coating the back 6, when said fabric 7 is present.
- the resistant layer 8 makes it possible to prevent oil from penetrating also on the side of the back 6 of the toothed belt 1 and is particularly advantageous when the toothed belt 1 is used in control systems wherein the back 6 of the belt is with pads or tensioners.
- the oil remains interposed between the contact surface of the pad or tensioner with the belt and the back of said belt and therefore penetration inside the mixture forming the body would be encouraged.
- the toothed belt 1 can be treated on all the external surfaces and, in particular, on the sides 10 where the body mixture is more exposed to the attack of oil, with a rubber resistant to swelling, for example ENDURLAST (Lord registered trademark) .
- the resistant inserts 3 are of the "hybrid" type, that is, they are produced in at least a first and a second material.
- resistant inserts 3 produced in two different materials allows greater adhesion of the resistant insert 3 to the mixture constituting the body of the belt 1 and reduces the decline in tensile strength in fatigue tests when oil is present.
- the resistant inserts 3 are preferably treated with a resorcinol-formaldehyde latex based composition, known as RFL, and in particular with an RFL composition suitable to prevent oil absorption.
- RFL a resorcinol-formaldehyde latex based composition
- zhe RFL used comprises a latex formed from a monomer containing nitrile groups and from a diene, for example HNBR or hydrogenated butadiene acrylonitrile.
- the latex is obtained from monomers containing nitrile groups in a weight percentage with respect- to the final copolymer similar to the preferred elastomeric material used to form the body of the toothed belt 1 described previously.
- the latex is preferably based on a copolymer formed from a diene and from a monomer containing nitrile groups in a percentage between 33 and 49 weight % with respect to the final copolymer, even more preferably based on a copolymer formed from a diene and from a monomer containing nitrile groups in a percentage of 39 weight % with respect to the final copolymer.
- Both the first and the second material used to produce the resistant inserts 3 according to the present invention are preferably chosen in the group constituted by glass fibres, aramid fibres, polyester fibres, carbon fibres and PBO fibres.
- the first material preferably has a lower modulus than the second material and is preferably wound around the second material.
- the first material is therefore chosen to solve problems of compatibility with the mixture of the surrounding body and the second material is therefore chosen to obtain a higher modulus in the toothed belt.
- the second material occupies a surface between 15 and 75% with respect to the total surface of the section. Even more preferably, the second material occupies a surface between 45 and 55% with respect to the total surface.
- the first material is preferably glass fibre
- the second material is preferably carbon fibre. Even more preferably, the glass fibres are high modulus fibres.

- the inserts according to the present invention have a twist of the "Lang's twist” type, that is, they have two twists in the same direction, as this construction has proven to be particularly effective.
- the toothed belt 1 is vulcanized according to common and known methods which are consequently not described in detail.
- a purely indicative example of a resistant insert 3 produced according to the present invention is described below and shown in Figure 5, where the number 50 indicates 9 twisted yarns in a first material which entirely surround 1 twisted yarn, indicated with the number 51 and produced in a second material.
- the first material is glass fibre
- the second material is carbon fibre.
- the glass fibres are wound around the carbon fibres to cover the carbon fibres entirely.
- this resistant insert 3 glass fins are treated with a treatment based on an adhesive composition, for example RFL, and then twisted a first time to form a twisted yarn. Subsequently, a certain number of these twisted yarns are wound around a carbon fibre twisted yarn.
- Figure 5 exemplifies the case in which the twisted yarns are 9.
- the twisted yarns form an insert with dimensions between 0.7 and 1.4 mm, in particular 1.15 mm if the construction is 34 tex 3 * 9, 400 tex *1.
- the first torsion to which the fins are subjected to form the twisted yarns consists in a number of torsions equal to 80 in a first direction S (clockwise) .
- the second torsions to which the twisted yarns are subjected in winding around the carbon are again 80 and are performed in the same direction S to form resistant inserts "S".
- These resistant inserts therefore have a twist of the Lang' s twist type, that is, they have two twists in the same direction.
- the torsions to which the carbon fibre fins are subjected to form a twisted yarn are 40 and these are also in the same first direction S.
- resistant inserts 3 are also formed which are twisted both times in a direction opposite to the first direction, that is, in the direction Z (counter-clockwise) to form resistant inserts "Z".
- the resistant inserts S and Z are then simultaneously deposited on the mould with a spiralling pitch between, for example, 2.6 and 3.2 mm and preferably 2.9.
- prior art toothed belts have resistant inserts made of high modulus glass which have modulus values at the most of 28 N/mm, where the modulus is defined as the force required to elongate by one millimetre a belt having a length of 1000 mm and a width of one millimetre.

- toothed belts 1, 20 and 30 in the respective control systems 11, 21 and 31 are in direct contact with oil.
- Figures 2 to 4 refer to control systems relative to movement of the balancing countershafts, but it is clear that the toothed belt according to the present invention may also be used in "cam to cam” systems or for movement of the oil pump. In these cases during operation the belt is partly immersed in an oil bath.
