ABSTRACT:
A sensor for responding to the rate of change of changing rotational speeds of a rotating vehicle wheel and including a flyweight coupleable for rotation in response to wheel rotation and selectively decoupleable in response to the exertion on the flywheel of a torque having a magnitude greater than a threshold magnitude due to a change in rotational speed of the wheel. In accordance with the present invention, 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 level. Provision is made for signalling of any occurrence of an excessive rate of change of rotational speed of the wheel, 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 of time during which the threshold rate is exceeded.
