Abstract

1277451 Antiskid braking systems TELDIX GmbH 30 May 1969 [30 May 1968] 27620/69 Heading F2F A device for detecting the change in rotational velocity of a vehicle wheel in an antiskid braking system includes a freely movable inertia mass 27 which revolves in a damping arrangement, its rotary motion with respect to the wheel being damped substantially in proportion to the rotational velocity of the wheel, as for example by liquid damping, magnetic elements 31 being arranged on the periphery of the mass to co-operate with a pick-up to provide pulses for controlling the braking.
