Abstract: A bushing assembly adapted for application in vehicle suspension systems includes an outer, generally cylindrical bushing member, an inner generally cylindrical bushing member arranged concentrically within the outer member. The two bushing members are interconnected by an elastomeric member disposed there between and bonded thereto to permit limited rotational displacement between the external and internal bushing members. An angular position sensor is at least partially embedded within the elastomeric member and operated to produce an output signal indicative of the relative angular position of the external and internal bushing members. The sensor includes a stator assembly including a permanent magnet, a galvanomagnetic sensing element and a flux guide defining at least one pole face, and a rotor including a flux guide defining a second pole face. An air gap between the two pole faces varies dimensionally as a function of the relative angular position of the stator assembly and rotor.

Abstract: An ultrasonic pulse/echo measurement arrangement includes an ultrasonic transducer (12), which is mounted spatially fixed on an air spring cover plate (4). The arrangement further includes a fixedly mounted reference reflector (14), a target reflector (16) mounted on a roll-off piston (8) or on the buffer (18) as well as a transmitter/receiver evaluation electronic circuit (30). The running time as well as the amplitude of the reference signal is evaluated to precisely determine the pressure present in the interior space of the air spring. The ultrasonic transducer (12) has a null/4-adaptation layer (22), whose impedance does not correspond to the geometric mean of the impedances of the ultrasonic transducer (12) and the ambient air of the interior space (20) of the air spring, but rather, is a mismatch. The evaluation electronic circuit (30) can be calibrated at ambient pressure for the determination of the inner pressure of the air spring. Preferably, the pressure measuring method according to the invention is also used to determine the running-time dependent spring height in an air spring (2) of a motor vehicle.

Abstract: A vehicle-mountable, suspension monitoring system produces suspension-analysis information which can be used to determine adjustments to a vehicle suspension. Sensor structure located adjacent the vehicle suspension is connected to a control/processing/display (CPD) unit located adjacent the vehicle operator. The sensor structure senses suspension related information and communicates the suspension related information to the CPD unit. The CPD unit receives the suspension related information and converts it to suspension-analysis information. The CPD unit stores the suspension-analysis information and displays it to the vehicle operator. Alternatively, the suspension-analysis information is downloaded from the CPD unit to a digital computer for display as waveform data.

Abstract: By passing the vertical acceleration through a phase adjusting filter and a gain adjusting filter, the phase of the vertical acceleration is advanced by 49 degrees so that the phase difference with respect to the actual relative velocity becomes 180 degrees in the neighborhood of the vehicle body resonance point, thereby making the phase of the vertical acceleration, in effect, coincident with the phase of the relative velocity. In the neighborhood of the vehicle body resonance point (1 Hz), the gain of the estimated relative velocity takes a small value. In frequency regions other than the neighborhood of the vehicle body resonance point, the gain of the estimated relative velocity is increased. Consequently, the controlled variable in the neighborhood of the vehicle body resonance point increases, and the controlled variable in higher frequency regions decreases. Damping force is adjusted in correspondence to the controlled variable. Thus, it is possible to improve ride quality in the neighborhood of the vehicle body resonance point (1 Hz).

Abstract: A position sensing device including two spaced conductive coils constituting a primary and secondary winding of a transformer. A coupling member is mounted to a moveable object. This movement adjusts or alters the transformer coupling between the primary and the secondary and produces a variable output signal which can be correlated to the position of the moveable member. An electronic module is coupled to a programmable controller and adjusts an output from the linear position sensor to linearize the output with relative movement of first and second members such as components of a vehicle shock absorber.

Abstract: A fluid cylinder assembly for a work machine includes a fluid cylinder having a housing which includes a first end wall, a second end wall, and a cylindrical side wall which collectively cooperate so as to define a piston chamber. The fluid cylinder also includes a piston housed for translation within the piston chamber, and a rod which extends through an opening defined in the second end wall. An ultrasonic transducer is secured to the cylindrical side wall of the fluid cylinder for transmitting ultrasonic vibrations into the piston chamber during a first time period and receiving ultrasonic vibrations from the piston chamber during a second time period. A control circuit is operatively coupled to the transducer. The control circuit generates a trigger signal which causes the transducer to transmit the ultrasonic vibrations during the first time period. The control circuit analyzes returned energy or echoes from within the piston chamber in order to determine piston location within the piston chamber. The output from the control circuit may be used to selectively disengage an "automatic lift" feature of a hydraulic lever assembly.

Abstract: An air spring apparatus with an internal height sensor is provided. The air spring includes an end cap member, a piston member and a flexible annular sleeve connected therebetween forming a sealed air chamber. The height sensor includes a sensing element and an indicating element and is mounted within the air chamber. The sensing element is mounted to one of the end cap member and piston member. The indicating element has a first portion connected to the end cap member, a second portion connected to the piston member, and an elastic member connected therebetween. The length of the elastic member defines an indicating level sensible by the sensing element such that movement of the end cap member relative to the piston member produces a much smaller proportional movement of the indicating level relative to the sensing element. This proportion reduction of movement allows a smaller sensor to measure a relatively large change in height.
