摘要： An active suspension system for a vehicle employing fluid powered force exertion units between the wheels and the vehicle body. The vehicle's engine operates a pump which provides pressurized fluid to operate the force exertion units under the control of a processing unit which monitors the rate of change of the power being consumed by the force exerting units and stores demand data indicative of the prior history of power demands placed on the engine by the suspension system. The processor calculates an autoregression moving average of the stored past demand values to form a prediction of future demand, thereby controlling the amount of power delivered by the engine in anticipation of the predicted needs of the force exertion units.

摘要： A die for use in extruding helical gears includes a die orifice at the upper end of the die teeth where the extrusion blank first enters the die. Each tooth is formed with a land directed parallel to the helix on the drive and trail side of the tooth and an end face perpendicular to the helix that intersects either a transition surface, directed perpendicular to the die axis, or a land. Alternatively, the end face can extend entirely across the tooth width from one land to the other without the use of the transition surface. Relief surfaces slope inwardly from the land and provide spaces within which the extrusion blank may expand without undue frictional contact with the die.

摘要： A method and tool for making an extrusion die wherein the extrusion has a lobed helical outer contour. An electrical discharge machining electrode has an identical outer contour. Mounted integrally with the electrode is a lead bar having a guide recess that makes a second helix angle with respect to the axis of the electrode. A guide pin fixedly mounted with respect to the moving assembly is located within the recess. Axial movement and rotation of the electrode through the die blank is controlled by the pin and recess.

摘要： A sleeve having a tapered outer surface is shrink or interference fitted over the outer surface of a die blank in which is formed a central bore, a larger diameter bore and a transition bore therebetween. The diametrical interference between the sleeve and the die blank is effective in producing an elastic deformation of the smaller diameter bore causing it to assume a conical shape. The die blank and sleeve are restrained within a casing and the inner surface of the die is formed by electrical discharge machining, electrical chemical machining or by other known methods. The die casing and sleeve are removed from the die, allowing the release of the stored strain energy of deformation which causes the smaller bore of the die to assume a conical shape tapering radially outwardly from its inner extremity. The sharp corner that results at the innermost end of the smaller bore is removed by lapping a straight-sided tool through the central opening of the die.
摘要翻译：具有锥形外表面的套筒收缩或干涉地装配在模坯的外表面上，其中形成有中心孔，较大直径的孔和其间的过渡孔。套筒和模坯之间的直径干涉有效地产生较小直径孔的弹性变形，使其呈现圆锥形。模具坯料和套筒被限制在壳体内，并且模具的内表面通过放电加工，电化学加工或其它已知方法形成。模具外壳和套管从模具中移出，允许释放存储的变形能量，这导致模具的较小的孔呈现从其内端径向向外渐缩的圆锥形状。通过将直边工具通过模具的中心开口研磨，导致较小孔的最内端产生的尖角被去除。
