Abstract
An arrangement for varying a pre-load on a control valve of a vehicle braking system in dependence upon vehicle loading includes a low frequency vibration sensor or an accelerometer for sensing the oscillation frequency of a sprung part of the vehicle and providing an output signal, preferably an electrical signal, indicative of the frequency, a signal processing circuit for processing the signal, the circuit including a filter which filters components of the signal which are not indicative of a frequency within the normal oscillation frequency range, and an arrangement for altering the pre-load in dependence upon the processed signal.
Claims19
An arrangement for varying a preload on a control valve of a vehicle braking system in dependence upon vehicle loading, including sensing means on the sprung part of a vehicle for sensing the oscillation frequency of the sprung part of the vehicle while in motion and means for changing said pre-load in dependence upon said sensed oscillation frequency.
