    • 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.
    • 一种用于检测车轮的角加速度和减速度的装置。 该装置包括:固定到车辆的旋转构件的圆柱形的第一活门构件,其与车辆车轮一起旋转,并且具有通过多个周向等间隔的孔形成的圆柱形侧壁;安装在所述旋转 构件通过阻尼装置相对于其有限的角度运动,圆柱形形状的第二活门构件固定到所述配重并且与所述第一活门构件以径向间隔的同轴关系布置,所述第二活门构件具有穿过其形成的圆柱形侧壁, 周向均匀的孔。 所述最后提到的孔布置成能够与所述第一提到的孔一起注册,但通常放置在与其对准的位置之外;一对光束发射和接收装置,固定地安装在车辆的非旋转构件上, 并且彼此相对,所述第一和第二活门构件设置在它们之间,其中当所述传感器重量被引起时,由于所述车轮的角加速度或减速度超过规定值,相对于所述旋转构件旋转, 所述第一和第二活门构件相互对准地放置成使得所述光束接收装置接收从所述光束发射装置发射的光束。
