摘要： A friction clutch for a draft gear assembly includes two outer stationary plates having outer surfaces engageable with the inner surfaces of a gear housing. A slot formed in each outer stationary plate receives a lubricating insert to prevent clutch sticking after closure and during a release of such gear. A pair of movable plates have outer surfaces frictionally engaged with inner surfaces of such outer stationary plates for absorbing energy during closure of such gear. A pair of inner stationary plates have outer surfaces frictionally engaged with inner surfaces of such pair of movable plates for absorbing energy during such closure. An inner surface of each inner stationary plate is tapered. Another slot formed in each tapered stationary plate adjacent an outer surface receives another lubricating insert which prevents clutch sticking during release of the gear. A pair of wedge shoes having a tapered outer surface frictionally engage an inner surface of such tapered stationary plates for absorbing energy during closure. An upper surface of the wedge shoe is tapered at an angle of between 46.5 and 48.5 degrees and a bottom surface of the wedge shoe is tapered at an angle of between 21.0 and 22.00 degrees. Another slot formed in each wedge shoe adjacent its outer surface has another lubricating insert to prevent clutch sticking during release of the gear. A center wedge having corresponding tapered surfaces frictionally engages an upper surface of a respective one of such pair of wedge shoes for absorbing energy during closure.

摘要： A method for monitoring the fill-up of a vehicle tire to the cold inflation pressure recommended for a cold tire condition. The method includes establishing a calibration temperature that corresponds to temperature of air in a cold tire condition, determining that air is being added to the tire, measuring the temperature of the air in the tire and adjusting the measured tire pressure to compensate for the difference between the measured temperature and the calibration temperature corresponding to a cold inflation temperature, comparing the adjusted pressure with the manufacturer's recommended pressure cold inflation pressure to determine that the recommended tire pressure has been obtained and generating a signal cognizable by the operator outside the vehicle so that the operator will cease filling the tire when the pressure is obtained.
