The specific embodiment

Come the utility model is further specified below in conjunction with specific embodiment, but the utility model is not confined to these specific embodiment.One skilled in the art would recognize that the utility model contained in claims scope all alternativess, improvement project and the equivalents that possibly comprise.

Referring to Fig. 1, a kind of construction machinery and equipment brake system comprises booster pump body 1, air compressor 2, foot brake valve 3, hydraulic actuating cylinder 4, brake clamp 5.Said air booster pump body 1 is provided with air chamber 11; Be provided with the gas piston assembly 111 suitable in the air chamber 11 with it; Said gas piston assembly 111 can free motion in air chamber 11 under gas promotes; Said gas piston assembly 111 is divided into first district 112, second district 113 with air chamber 11; Said foot brake valve 3 is provided with detent channel and exhaust passage, and the detent channel of said foot brake valve 3 is communicated with the formation braking function through the 3rd pipeline 6 with air chamber second district 112, and the exhaust passage of said foot brake valve is communicated with the air-breathing function of formation through the 4th pipeline 7 with air chamber second district 113; The 5th pipeline 8, the five pipelines that air chamber two districts 113 also are provided for exhaling are provided with outlet valve 13.

Be provided with a push rod 114 in the said air chamber 11, these push rod 114 1 ends link to each other with gas piston assembly 111, and the other end links to each other with hydraulic piston assembly 41.41 suitable being provided with in the hydraulic actuating cylinder 4 of hydraulic piston assembly, hydraulic actuating cylinder 4 is connected through first pipeline 9 with brake clamp 5, and its in-to-in hydraulic oil can provide brake power under the effect of hydraulic piston assembly 41, for brake clamp 5.Said foot brake valve 3 is communicated with through second pipeline 10 with air compressor 2; Said air compressor is the engine installation for gas-circulating system; Be provided with removable cleaning device 21 between itself and the foot brake valve 3; Said cleaning device 21 is provided with filtering net 22, and the gas of air compressor 2 just can filter through cleaning device 21.Like this, only need cleaned at regular intervals or change the filtering net 22 in the cleaning device 21, just can guarantee the quality of inner loop gas.
