Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
This band promotes stroke spring braking chamber, the housing that constitutes by protecgulum 6, middle body 7 and cylinder 25, protecgulum 6 and middle body 7 joints are by clip 17, second bolt 15 and second nut, 16 bandings, protecgulum 6 is provided with first nut 3, first spring washer 4, is installed on the automobile support by first nut 3 and first spring washer 4.Be provided with seal ring 26 at middle body 7 and cylinder 25 joints, and the two is fixed together by the 3rd nut 27, the three spring washers 28 and the 3rd bolt 29.Be provided with push rod 5 in the housing, these push rod 5 front ends stretch out that protecgulum 6 is outer to be connected with clevis 1, and the opening that protecgulum 6 stretches out at push rod 5 is provided with the block set 2 of preventing dust, and dirt-proof boot 32 itself and protecgulum 6 connecting ends are fixed on this dustproof block set 2.The rear end of push rod 5 is connected with push rod dish 22, and is butted on the epithelium 30 that is fixed in middle body 7 by this push rod dish 22; Be arranged with Returnning spring 31 on the push rod 5, these Returnning spring 31 1 ends are butted on protecgulum 6, and the other end is butted on push rod dish 22; Form pressurizing chamber in the epithelium 31, have the compressed air inlet of pressurizing chamber on the middle body 7.Described push rod dish 22 rear ends are connected by plug screw 21, piston guide bush 18 and the piston 24 in ram seat 33 and the cylinder 25, are provided with nylon jacket 8 and O RunddichtringO 9 between the endoporus on the external diameter of piston guide bush 18 and the middle body 7.Between piston 24 and the cylinder 25 brute spring 23 is arranged, brute spring 23 is having spring buffer pad 12 with cylinder 25 contacting points, and is provided with muffler 13 and rubber elbow 14, between piston 24 and cylinder 25 inwalls y-type seal ring 10 and piston ring 11 is arranged.Discharge bolt 20 1 ends and be connected with capstan nut 19, the nut seat 25-1 that the other end passes on the cylinder 25 is connected with piston 24 with piston guide bush 18.
Working principle: push rod 5 front ends are connected with break by clevis 1.During use, input pressurized air is propped up promotion push rod dish 22 with epithelium 30, afterwards driving push rod 5 moves forward, the final realization braked, and this is the one-level stroke, and the spring force that cylinder 25 has been full of pressurized air and brute spring 23 generations balances each other, the words of bigger if desired braking force, only need exhaust, because the effect of brute spring 23 promotes piston 24, piston guide bush 18 to left movement, then promote push rod 5 to left movement, form the secondary stroke.Because dirt-proof boot 32 is flexible, collapsible, in the process that push rod 5 moves, dirt-proof boot 32 launches thereupon, can prevent effectively that dust from falling in the housing in addition.
