    Abstract: An air spring (2) essentially includes two end elements (4, 6) and an electrically conductive rolling-lobe flexible member which is pressure-tightly arranged therebetween and is made of a flexible elastomeric electroconductive material (14). A reinforcement (16) formed by two cord fiber plies (16a, 16b), which are made of fibers (18), are vulcanized into the flexible member. In order to determine the height (h) of the spring, preferably, the two cord fabric plies (16a, 16b) are provided with a number of highly conductive fibers (18a) which are arranged at the beginning and the end of each ply in a parallel direction to each other, thereby forming two conductive strips (24a, 24b). The conductive strips (24a, 24b) are disposed oppositely to each other and are electrically connected at the end of the rolling-lobe flexible member (8) in such a way that a conductive loop (24) is formed and each strip is used as an element in a branch for an alternating-current measuring bridge (28). The filaments (20) of individual fibers (18) or only certain filaments (20a) of the fibers (18) can be electrically conductive. In addition to determining the height (h) of the spring in a motor vehicle, the inventive device can also be used for determining the air pressure in the flexible member of the air spring (2), the temperature (T) of the flexible member walls and other measurement quantities.

    Abstract translation: 空气弹簧（2）基本上包括两个端部元件（4,6）和压电密封地布置在其间并由柔性弹性体导电材料（14）制成的导电滚动弹性构件。 由纤维（18）制成的两个帘线纤维帘布层（16a，16b）形成的加强件（16）被硫化成柔性构件。 为了确定弹簧的高度（h），优选地，两个帘线织物层（16a，16b）设置有多个高导电性纤维（18a），其布置在每个帘布层的开始和结束处 彼此平行的方向，从而形成两个导电条（24a，24b）。 导电条（24a，24b）彼此相对设置并且在滚动波瓣柔性构件（8）的端部处以这样的方式电连接，使得形成导电回路（24），并且每个条带用作 用于交流测量桥（28）的分支中的元件。 单个纤维（18）的细丝（20）或仅纤维（18）的某些长丝（20a）可以是导电的。 除了确定机动车辆中的弹簧的高度（h）之外，本发明的装置还可以用于确定空气弹簧（2）的柔性构件中的空气压力，柔性构件的温度（T） 墙壁等测量数量。

    Abstract: A snowplow control system is provided that uses the distance between the vehicle frame and the ground or wheel axle as an input to a feedback loop useable to provide increased control over the pressure exerted by the plow blade. The control system allows the plow to operate in various modes of operation including a manual mode, a float mode, and a down pressure mode. The control system interfaces with the vehicle operator by way of a controller that is preferably operable from within the cabin of the vehicle.

    Abstract: A suspension control unit as well as a control valve for such unit are provided which are incorporated in a computerized suspension system which automatically and continuously monitors and control's a vehicle's ride performance. The suspension control unit is composed of an actuator and a fluid control unit. A valve is coupled to the actuator for controlling the fluid pressure within the actuator. The valve has an annular body having a side inlet passage and an outlet opening in communication with the reservoir. A poppet driven by a solenoid is slideably fitted within the body wherein the poppet can slide between a first position blocking flow to the outlet opening and a second position not blocking the flow to the outlet opening. The poppet has a shoulder that is exposed to the inlet. Fluid pressure to the inlet of the valve acts on the differential area of the poppet to produce an poppet retracting force which is opposed by the force of an electrically adjustable solenoid. When pressure reaches the solenoid setting, the poppet is retracted to the open position, permitting flow through the valve.
