  • On-board apparatus for monitoring the condition of shock absorbers
    Patent number: 4458234
    Abstract: A vehicle equipped with a spring and shock absorber suspension has a piezoelectric wafer interposed between the spring and a part of the vehicle in such manner as to cause the wafer to be subjected to a compressive or decompressive force in response to relative vertical movement of the vehicle part and the suspension. The application of such force to such wafer results in the generation of an electrical current pulse which is transmitted to an indicator mounted within the vehicle in a position to enable the driver to monitor the condition of the shock absorber.
