Abstract
A hydraulic antilock brake device, comprises an oil tank filled with hydraulic oil, a pump electric motor group, a one-way valve, a piloted overflow valve, a manual two-position three-way valve, an adjustable throttling valve, an adjustable throttle valve, a high pressure oil inlet tube, and an oil return tube. the high pressure oil inlet tube and the oil return tube are communicated with a hydraulic controlled negative feedback two-position four-way valve, which is communicated with a brake cylinder connected with a friction sheet. Fast valve holes are provided at two ends of an inner chamber of said hydraulic controlled negative feedback two-position four-way valve, and fast valves are located in the fast valve holes. Two ends of an inner chamber of said braking cylinder are provided with feed-back grooves communicated with the fast valve holes by oil passage. The hydraulic antilock brake device can ensure the driving safety.
