ABSTRACT:
A device for detecting angular accelerations and decelerations of a vehicle wheel. The device comprises a first shutter member of cylindrical shape secured to a rotating member of a vehicle, which rotates with a vehicle road wheel, and having a cylindrical side wall formed therethrough with a multitude of circumferentially equispaced holes, a sensor weight mounted on said rotating member through damping means for limited angular movement relative thereto, a second shutter member of cylindrical shape secured to said weight and arranged in radially spaced coaxial relation with said first shutter member, said second shutter member having a cylindrical side wall formed therethrough with a multitude of circumferentially equispaced holes. Said last-mentioned holes being arranged so as to be registrable with said first-mentioned holes but normally placed out of registry therewith, a pair of light-beam emitting and receiving means fixedly mounted on a nonrotating member of the vehicle in radially aligned, spaced and opposite relation to each other with said first and second shutter members disposed therebetween, wherein when said sensor weight is caused, due to an angular acceleration or deceleration of said wheel exceeding a prescribed value, to rotate relative to said rotating member, said holes in said first and second shutter members are placed into registry with each other so that said light-beam receiving means receives light beam emitted from said light-beam emitting means.
