Abstract

A sensor for responding to the rate of deceleration of a rotating vehicle wheel includes a flyweight 10 coupleable for rotation in response to wheel rotation and selectively decoupleable in response to the exertion on the flyweight of a torque having a magnitude greater than a threshold magnitude due to a deceleration of the wheel. A control device is operatively connected with the flyweight for exerting on the flyweight torques resisting decoupled rotation of the flyweight and is operable for changing the level of torque from a first level to a second, lower level when said threshold magnitude is exceeded. Occurrence of an excessive rate of deceleration of the wheel is signalled, and the control mechanism is operable in response to such signalling for changing the level of torque and thereby for causing the sensor to signal continuously for the interval during which the threshold rate is exceeded. The resisting torque is applied to the annulus 35 of a planetary gear 12 between input shaft 11 and flyweight 10 by magnetic hysteresis drum brake 20. <IMAGE>
