Abstract
A transformer device for the detection of vehicle attitude, comprising a signal sensor, which is arranged inside the cylinder of the shock absorber coaxially with the piston thereof. The sensor cooperates with an amplifier for amplifying the detected signals. The sensor includes a differential transformer comprising a primary AC-fed coil and two secondary coils each having one of their ends electrically connected to the other. The remaining end of each secondary coil is electrically connected to the amplifier to which the output sensor signal is applied to be amplified, before being applied to the output of the device. The signal is a function of the voltage induced voltage in the secondary coils of the differential transformer which is determined by the piston position with respect to the primary coil and secondary coil and thereby the relative positioning of the piston inside the shock absorber cylinder.
