A speed sensor (6) is arranged in the piston assembly (11), and when wheel compression hydraulic efficiency gear, slip oil pocket and piston assembly relative motion make the hydraulic oil in A chamber go into the B chamber via the C orifice flow on the piston assembly (11).When the flow velocity of hydraulic oil was higher than regulation numerical value, speed sensor (6) was about to the sealing of C hole.
There is a spring (5) supporting a globe valve in the piston assembly (11) or other similarity energy thresholds (4) are sealing passage D.After speed sensor (6) sealed the C hole, the fluid oil in A chamber and gas were compressed pressure are increased, and surpass regulation numerical value and force globe valve or other similarity energy threshold (4) open channel (D), play deceleration effort.At this moment hydraulic efficiency gear applies application force to wheel, makes wheel decelerates.And slide to a certain standing height under hydraulic efficiency gear is vertical after, hydraulic oil flows into the B chamber from the A chamber speed is slow relatively, and speed sensor (6) can not seal the C hole, and hydraulic efficiency gear can not apply application force to wheel.
For hydraulic efficiency gear (2) is fixed in the guide cylinder (1), only establishing at the bottom of piston assembly (11) bar, red seat (17) prevents that with elastic spring (19) bearing pin is loosening with bearing pin (18) connection And, in guide cylinder (1) sidewall relevant position perforate, insertion ends abatement (15) will only write off (15) pinning to ending red seat (a 17) position-limiting action ， And with spring cotter (16).
Magnetic valve controller of the present invention is by a coil (7), electromagnet (8), and check valve (10) and spring (9), cavity shell body (27), valve seat (26), iron core (28) is formed.Electromagnetic valve is connected with deceleration top guide cylinder with screw.The cavity shell body (27) of electromagnetic valve is established connecting bore (24) with guide cylinder junction, deceleration top, makes with the guide cylinder inner chamber to be communicated with.Check valve (10) can connect closely connected with valve seat (26), also can divide the open electromagnetic valve sidewall to establish air extractor vent (25), be communicated with atmosphere, status requirement guide cylinder inner chamber air is set when vehicle wheel rolling presses, can gets rid of, but air can oppositely not enter the guide cylinder inner chamber when closed check valve by this hole.
In order to increase sealing property, piston rod and sliding oil cylinder contact position set on lining (20), following lining (14) is established at least one seal ring respectively.End on the red seat (17) that at deceleration top guide cylinder the space filling piece being set, to reduce the guide cylinder cavity volume, increase negative pressure of vacuum, sealing circle and space filling piece are made by rubber or High molecular material.Seal cover cap (12) adopts the integral structure of aluminum alloy materials or similarity material.
