Case Studies Vespel® - Transportation Applications MINI Autos Stay on the Go With Vespel® for CVT Sealing Rings High reliability, light weight and low assembly costs come with sealing rings made of DuPont™ Vespel® SP polyimide in a continuously variable transmission (CVT). » More Thrust plugs for rear windshield wiper motor Thrust plugs for rear wind-shield wiper motor to take the axial load from the worm gear. » More Ignition distributor coupling and rubbing block Ignition distributor coupling and rubbing block for mechanical ignition distributor to actuate breaker points. » More Ford tractors use Vespel® parts in gearbox Thirty-seven Vespel® polyimide parts serve as wear pads, thrust washers and seal rings in a new top-of-the-line 16x16 gearbox for Ford New Holland mid-size tractors. » More Rings, stepped bushings, and orifice plates for forklifts and other equipment In carburetors for propane- and natural-gas-fueled engines for forklifts and other equipment, Vespel® polyimide parts have improved wear resistance and vehicle emissions in replacing phenolics for rings, stepped bushings and orifice plates. In 100,000 mile durability tests, the phenolic parts wore rapidly against aluminum, causing overly rich fuel mixtures and excessive exhaust emissions. » More Windowlift Motor Saves Weight, Works More Efficiently Windowlift motors installed in Ford cars are a design made with seven DuPont polymers. The motor gear housing, injection molded from Zytel® HTN high performance polyamide resin, marks a major shift away from traditional die-cast aluminum housings. » More Vespel® seals improve transmission reliability Seal ring for CVT (continuously variable transmission). » More Excellent heat and wear resistance of Vespel® parts result in reliability and lower weight Thrust plugs made out of Vespel® polyimide are used in ITT’s powerful, reliable and economic automotive rear windscreen wiper motor (SW3P). Gears made from Delrin® acetal resin also feature in this application. » More Heat-Resistant Thrust Washers Help Keep 4WD Trucks Rolling New Venture Gear Inc. selected Vespel® polyimide for 14 thrust washers in its robust new four-wheel-drive transfer case for light trucks after comparative testing of polyetheretherketone and Vespel® parts. The case is rated for trucks with gross vehicle weights from 8,800 to 17,500 lbs (3,992 to 7,938 kg). » More Low wear and high reliability for automotive pedal sensors Over-moulded bushings for gas pedal sensor used in almost all Mercedes passenger cars. » More Increased reliability with Vespel® Closing flap guide bushing for Exhaust Gas Return system (EGR). » More Vespel® significantly helps increase performance and life span of transmissions Seal rings and thrust washer used in B13 and B41 transmissions for Renault Agriculture Ceres and Ergos tractors. » More Much better sealing and assembly with seal rings of Vespel® Sealrings (7) for automatic DP0 and AL4 transmissions located at the accumulator, the oil pump shaft and the hydraulic lock-up system areas. » More Click here to go to the Case Studies Index Page.
