Abstract: A vehicle suspension system (10) has a spring (11) operatively arranged to act between sprung (15) and unsprung (13) masses. The coil (24) of an LVDT (22) is mounted on the sprung mass. The core (23) of the LVDT is connected to an intermediate portion (25) of the spring. Thus, displacement of the core relative to the coil will be a proportional fraction of the relative displacement between the masses. This arrangement allows the use of a short-stroke position-sensing transducer to measure the relative displacement between the two masses.

Abstract translation: 车辆悬挂系统（10）具有可操作地布置成在弹簧（15）和簧下（13）质量块之间作用的弹簧（11）。 LVDT（22）的线圈（24）安装在弹簧质量上。 LVDT的芯部（23）连接到弹簧的中间部分（25）。 因此，芯相对于线圈的位移将是质量之间的相对位移的成比例分数。 这种布置允许使用短行程位置传感传感器来测量两个质量块之间的相对位移。

Abstract: A variable electrical resistance device for monitoring displacement of a mechanical component such as a vehicle road wheel suspension system having a housing; an electrically resistive track and conductive slip ring on a support in the housing; electrically conductive wipers on a rotatable carrier provided with a spindle for coupling to the component. The wipers traverse the resistive track and the slip ring respectively. The support is mounted on springs or flat strips of resilient metal, so as to be displaceable away from and towards the wipers. A solenoid, of double-acting type or acting in association with the bias of the springs, has an armature operating to effect displacement of the support away from and towards the wiper whereby contact between the wiper and track may be broken, or the contact pressure therebetween reduced, when monitoring is not required, thereby prolonging the life of the wiper and track assembly.

Abstract: An ultrasonic system is responsive to the relative position of a movable device within a fluid-filled structure. A transducer transmits ultrasonic signals from a location fixed within the structure to the device for reflection thereby and for picking up the reflected signals. A reference target within the fluid, attached either to the structure or the device, also reflects the transmitted ultrasonic signals from also being picked up by the transducer, such reference target being a predetermined fixed distance relative to either the device or the structure, whereby the different picked up signals reflected from the device and reference target will have a timed relationship corresponding to such fixed distance, measurement circuitry means is responsive to the picked up signals reflected from the device and to such timed relationship for providing an output signal which is a function of change in the position of the device within the structure, being includes circuitry responsive to the timed relationship for causing the output signal to be compensated for changes in the velocity of ultrasonic signals in the fluid resulting from changes in parameters thereof subject to causing errors in the output signal. The structure is, for example, a fluid cylinder and the movable device is a piston within the cylinder. Alternatively, sensing of the parameter is used for output signal compensation.

Abstract: A floating axle assembly for a vehicle. The assembly comprises an axle extending transverse to the longitudinal axis of the vehicle and beneath its frame. Wheels are connected to the axle and reinforcement members extend rearwardly from the axle to attachment points on the frame. Hydraulic cylinder assemblies are positioned above the axle and provide required support. The axle is telescopic and height adjustable. The configuration allows the center area of the vehicle to be cleared for crop flow.

Abstract: Pneumatic suspension system for automotive application in which sprung and unsprung masses are supported by variable volume air spring units and incorporating compressor and exhaust valve devices for supplying an exhausting pressurized air from the units to adjust the height between the masses. A Hall effect device effective across a pressure boundary senses the position of a magnet movable within one of the air spring units and reflects relative movement of the sprung and unsprung masses to effect control of the supply and exhaust of air from the units. By axial movement of the Hall device, dead band width can be established to accommodate normal ride motions between sprung and unsprung components. By rotating the Hall device at any axial position, the vehicle bumper height can be selectively increased or decreased.

Abstract: A vehicle level detector detects a change in the elevation of a vehicle body as reflected in a change in the relative distance between a suspension member for wheels of the vehicle and the vehicle body. The detector comprises a magnet and a magnetoelectric transducer element disposed in opposing relationship. One of the magnet and the transducer element is disposed for displacement relative to the other in accordance with a varying elevation of the vehicle body, thus permitting a change in the elevation of the vehicle body to be detected by sensing the displacement.

Abstract: A digital or analogue regulator circuit for activating a pump or pressure reducing valve, whose action respectively raises and lowers the body of a vehicle relative to the rear axle, each operating with a time delay so that temporary level changes will not initiate a regulatory process. Feedback circuits provide hysteresis. In both embodiments, level changes are represented by changes in the collector potential of a transistor and positive and negative feedback are provided to the base of the transistor to create the hysteresis or dead zone. In the digital embodiment, a counter generates the delay and the negative feedback.
