ABSTRACT:
An antilock brake device for vehicles having a sensor which senses a possibility of locking of a wheel, during braking of the wheel, by an overruning of a flywheel which generates a release signal. A hydraulic pump having a cam shaft rotated in association with the wheel generates hydraulic pressure for antilock control. A gear unit as a transmission for transmitting rotation of the wheel at an increased speed to the flywheel comprises an input member located within and connected to a hub of the wheel, a ring gear formed on the input member, a planetary gear meshed with the ring gear and a sun gear meshed with the planetary gear. The planetary gear is secured to a cam shaft supported on a stationary casing. The flywheel of the sensor disposed within the hub is connected to the gear unit through a drive shaft. The sensor is supported on an axle extending through the hub. The casing encasing therein the antilock controller is disposed at an open mouth of a hub recess, and the input member is provided so as to encircle the sensor. A transmission torque limiter is provided between the wheel and the sensor. The input member is connected to the hub by bolts extending through a hub wall from the side thereof opposite the side where the recess is positioned. One side wall of the casing is supported on one axial end of a cylinder shaft fitted on the axle, and the input member is rotatably supported on the other axial end of the cylindrical shaft. A coupling which assumes a connecting state when the shaft is fitted on the axle is provided between the input member and the wheel.
