    • 专利摘要:
    Apparatus for braking a rotating member which has a fluid pressure responsive brake to which pressurized fluid is supplied for braking the rotating member, an anti-locking device interposed between the brake and the source of supply of fluid pressure for cyclically decreasing and increasing the fluid pressure supplied to the brake, and a control interposed between the brake and the fluid pressure source for limiting the rate of rise of fluid pressure supplied to the brake. Limitation of the rate of rise of fluid pressure applied to the brake governs reapplication of braking forces by the brake and thereby aids in optimizing brake performance.

    专利说明:

    This invention relates to hydraulic brake systems equipped with anti-lock devices.
    The purpose of the invention is to increase the reliability of braking.
    The drawing shows a hydraulic device for braking the wheels of a motor vehicle.
    The device comprises a wheel brake cylinder 1 of a wheel 2 connected to the main brake cylinder 3 by a pipe 4. A sensor 5 is connected to the wheel 2 and controls the pressure modulator 6. In the housing 7 of the modulator 6, the bore 8 is installed, the winding 9 is spring-loaded 50 shut-off valve 11, controlled by the rod core 8 preloaded by the saw arm 12. On the other side of the core 8 there is a locking element 13 with a spring 14 connected with stem bore 8. A spring 15 and a pump piston 16 are built into the modulator 6. Pipeline 4 has a non-return valve 17, having a housing 18, seats 19 and 20, a platter
    a second locking element 21 with a central throttle bore 22 and a spring 23. In the element forming the saddle 19 there are made bypass channels 24,
    When braking, the pressure from the master brake cylinder 3 through the open valve 11 of the modulator 6, the channels 24 and the pipeline 4 is fed into the brake cylinder 1.
    When blocking conditions occur, sensor 5 delivers a signal through which current is applied to winding 9 and to piston actuator 16. Valve II closes and shut-off element 13 blocks communication between modulator 6 and non-return valve 17,
    The piston 16, periodically creating a discharge, pumps fluid from cylinder 1 to cylinder 3.
    The valve 17 serves to limit the filling rate of the cylinder 1. The locking element 21, compressing the spring 23, is pressed against the saddle 20 and the liquid passes to the cylinder I only through the throttle hole 22.
