Abstract: This invention patent is related to an electric emitting wheel assembly (1), belonging to the electronic component field used in the automotive industry, which was developed to identify or monitor parameters of the rotating part (100) such the crankshaft or others. This assembly is made of: the sensitizing ring (2) (tone wheel) of electric material conducting, mounted electrically insulated around the rotating part (100), connected to an external voltage supply, suitable for generating and temporarily storing in the Gauss surface of the ring (2), an electric field (40). This sensitizing ring (2) also has a commutation strip (5) selected to emit an electric field (40) with regular intermittency, generating the specific intermittent electric field (40)?. The sensor capacitive (30), reads the specific intermittent electric field (40).

Abstract: This abstract refers to an invention patent related to an emitter wheel assembly, more particularly with the association of a special sensitizer ring set (1) and a special capacitive sensor (20), and an electrostatic device (80) for recharging the ring, the said ring being able to generate an electric field (40), provided with temporary initial charge and being rechargeable by the electrostatic recharging device (80), and the capacitive sensor being able to be sensitized by the electric field (40); the said assembly being developed for particularly automotive applications and/or related applications requiring a device for identifying and monitoring the rotations, positions, angulations, speeds an other attributes of a rotating part, such device having low cost and long useful life.

Abstract: A retainer and insert assembly used to repair a damaged end of a crankshaft. The assembly includes an insert, which is applied directly on the damaged region of the crankshaft and has a cylindrical bushing having a rubber seal layer, wherein the bushing includes a vulcanized interior surface. A retainer is disposed around the insert and which sealing contacts the bushing. A mounting and centralization device centers and mounts the insert and retainer on the crankshaft.

Abstract: A low-torque dynamic seal that seals at least one interstice defined between a moving part and a fixed part, which on a first side, opens at a location external to the fixed part, and on a second or other side, opens at a location internal to the fixed part and contains a lubricant fluid having a viscosity that is lower than conventional grease or other such lubricants. The seal includes a treatment region having adjacent surfaces of the moving and fixed parts, which define the at least one interstice. The adjacent surfaces attain superficial tensions that are substantially lower than a superficial tension of the low viscosity fluid so that the low viscosity fluid is not able to wet the adjacent surfaces. As a result, the interstice between the adjacent surfaces does not leak the low viscosity fluid therefrom.

Abstract: A sensitizing ring for sensors having a reduced manufacturing cost and an improved profile shape manufacture with a diameter of 120 mm or less. The sensitizing ring of the present invention is used to measure the rate of rotation and position of a rotating element. The sensitizing ring of the present invention is usable in more applications, especially in the automotive industry. The sensitizing ring comprises a body, a plurality of teeth provided on an outer periphery thereof, and a plurality of gaps interposed between the teeth. The body is made of a polymeric material interspersed with a ferromagnetic material. Alternately, the body is made of a polymeric material having a coating layer of ferromagnetic material. In a further embodiment, the body includes ferromagnetic material in the polymeric material forming the teeth but does not include ferromagnetic material in the polymeric material forming the gaps.
