Abstract
The invention provides a method for dismounting a brake body in a Dena drive axle. The method comprises the steps that a brake body spring pressing sleeve, a screw pressing disc and an adjusting screw are manufactured; a hub is dismounted, and the braking body spring pressing sleeve is arranged outside a supporting shaft in a sleeving manner and abuts against a piston ring; the screw pressing disc penetrates the supporting shaft, a cap nut is used and screwed to the top end of the supporting shaft, and the screw pressing disc is fixed; and the adjusting screw abuts against the braking body spring pressing sleeve, a spring is compressed, and dismounting is finished by unscrewing a brake body fixing screw. The method solves the problem that during brake body dismounting and mounting, the compression force of the spring cannot be released; the overhauling efficiency and safety are high; and an adopted tool can be manufactured, and the dismounting and mounting cost is reduced.
Description
Technical field
The invention belongs to drive axle maintenance field, be specifically related to a kind ofly be applicable to any moral and receive the dismounting of brake body of spring braking hydraulic pressure release of POSI-STOP.
Background technology
Drive axle is positioned at power train end, can change the rotating speed from speed changer and torque, and they are passed to the mechanism of driving wheel.Fig. 1 is drive axle brake schematic diagram, driving force is delivered to wheel limit two stage reducer by semiaxis by differential mechanism, and then take turns limit two stage reducer by power transmission on wheel hub, last wheel hub drives tire rotation, wherein brake body is when braking, and provides interception to equipment.As shown in Figure 2, movable friction plate and still, when braking, press together under spring restoring force effect by equipment in brake body, rely on the effect of frictional force to be stopped extremely on the wheel limit of rotation, thus are stopped by equipment.In the process of brake release, hydraulic system forms a road hydraulic oil, and under the effect of this special envelope, bear against piston on piston ring, piston ring acts on spring, by spring-compressed, thus release movable friction plate and still, make it to be separated, release moving plate.
Meishan iron mine scraper drive axle uses moral to receive product mostly, and moral is received drive axle and adopted the safety arrestment form of the spring braking hydraulic pressure release of POSI-STOP at present.The drive axle of this kind of mode of braking is in maintenance process, and the installation and removal of brake body are the biggest problem of maintenance, if misoperation not only can extend the repair time, reduces overhaul efficiency, causes spring compression force to discharge simultaneously, there is potential safety hazard.
Therefore, receiving drive axle for moral, to develop a kind of brake body method for dismounting with higher overhaul efficiency and security be those skilled in the art institute urgent need to solve the problem.
Summary of the invention

Further, the concrete grammar of step (3) is: by adjusting screw(rod) through adjustment hole, withstand brake body spring press-cover, and going forward side by side, it is fastening to be about to adjusting screw(rod), makes brake body spring press-cover withstand piston ring and acts on spring release brake; After brake release, dismounting is used for the standing screw of fixing brake body; Slow release adjusting screw(rod), dismantles brake body.
The invention provides a kind of moral and receive the method for dismounting of brake body in drive axle, concrete steps are: according to the size of back shaft and the relative position of piston ring and the relative position determination brake body spring press-cover of brake body spring press-cover and back shaft and screw rod platen, and make brake body spring press-cover, screw rod platen and adjusting screw(rod); First wheel hub is dismantled after completing, brake body spring press-cover is inserted in back shaft, and matched with the dynamic friction in brake body and still by the guiding tooth bar that brake body spring press-cover both sides are provided with, brake body spring press-cover is arranged in the chamber of brake body, and makes the boss of brake body spring bottom withstand piston ring; Then screw rod platen is inserted in back shaft, by and cap nut is screwed into the top of back shaft, because the surface of back shaft is provided with boss equally; The screw rod platen of ring-type and back shaft mating holes form boss the inside of screw rod platen is same, and two boss support mutually, then by and cap nut screw rod platen and back shaft are fixed; Afterwards adjusting screw(rod) is passed adjustment hole, withstand brake body spring press-cover, then adjusting screw(rod) is carried out fastening, make brake body spring press-cover withstand piston ring, and act on spring release brake; After brake release, the standing screw being used for fixing brake body is dismantled, afterwards slow release adjusting screw(rod) again, brake body is dismantled.
When brake body is installed, adopt reverse procedure.
Further, the material of brake body spring press-cover is 45# steel, and quenching hardness is 45-49HRC.
Reliability during in order to ensure that brake body spring press-cover in the present invention uses and steadiness, use 45# steel to manufacture, and quenching hardness when manufacturing is 45-49HRC.
Further, the quantity of adjustment hole is 2-6, and quantity is even number.
Fastening in order to enable to carry out when fastening adjustment screw rod diagonal angle, ensure that brake body spring press-cover compresses piston ring equilibrium, the quantity of the adjustment hole in the present invention is chosen as 2,4 or 6, and can select the adjustment hole of suitable quantity according to the size of screw rod platen and brake body spring press-cover.
Compared with prior art, beneficial effect is in the present invention: (1) solves the difficult problem that when brake body removes and installs, spring compression force cannot discharge; (2) overhaul efficiency and security high; (3) instrument used can self manufacture, reduces and removes and installs cost.
