Brake drum 505 and friction block 506；6 right side of support frame is symmetrically fixedly mounted in hydraulic cylinder 501；The setting of 501 down either side of hydraulic cylinder
There is featured piston block 507；Brake block 502 is fixedly mounted on featured 507 lower section of piston block；Major trough is provided in the middle part of hydraulic cylinder 501
Mouth 508；508 liang of middle side parts of major trough mouth are provided with sliding slot 509 in the height direction；Pacify below hydraulic cylinder 501 509 bottom of sliding slot
Equipped with sealing cover 510；509 inner upper of sliding slot slidably connects auxiliary piston block 511；509 lower inside of sliding slot is slidably connected
There is sliding block 512；It is connected between sliding block 512 and auxiliary piston block 511 by reset spring 503；It is fixedly welded in the middle part of two sliding blocks 512
There is fixing axle 513；505 shaft of brake drum is connected to 513 middle part of fixing axle；In 513 periphery of fixing axle inside brake drum 505
It is evenly arranged with multiple casings 514；It is slidably connected at below friction block 506 inside casing 514；506 bottom of friction block and casing
514 inner bottoms are connected by holddown spring 504；506 top of friction block and 505 inner wall of brake drum are in contact；Brake block 502
Middle part is provided with through-hole 515；Through-hole 515 and brake drum 505 are corresponding in the direction of the width；505 middle part periphery of brake drum
It is provided with multiple heat release holes 516.
In use, step 1, in conjunction with shown in Fig. 1-6, when braking, 501 oil inside offering of hydraulic cylinder, to push featured piston
Block 507 and auxiliary piston block 511 synchronize move downward, featured piston block 507 pushes brake block 502 to synchronize downwards when moving downward
Movement, so that brake disc holding is realized brake by two brake blocks 502, is braked using tight-holding type, good braking effect,
Transmission disc brake is solved as clamped-in style braking, the problem of braking effect difference；By resetting bullet when auxiliary piston block 511 moves downward
Spring 503 pushes sliding block 512 509 to synchronize and move downward along the chute, and sliding block 512 moves downward to pull system by fixing axle 513
Dynamic roller 505 moves downward, when brake drum 505 and brake disc outer ring are in contact, effect of the auxiliary piston block 511 in oil pressure
Under continue to move downward, thus by 511 compression reseting spring 503 of auxiliary piston block, under the action of 503 elastic force of reset spring
Drop brake drum 505 is tightly attached to brake disc outer ring, to realize that brake disc drives brake drum 505 to rotate.
Step 2, in conjunction with shown in Fig. 1-6, when brake disc drives brake drum 505 to rotate, because of fixing axle 513 and sliding block 512
Welding is acted on by 504 elastic force of holddown spring by friction block 506 so fixing axle 513 and friction block 506 cannot rotate
It is pressed on 505 inner wall of brake drum, when relatively rotating between brake drum 505 and friction block 506,506 He of friction block
505 inner wall of brake drum rubs, so that certain friction catch effect is formed, between friction block 506 and brake drum 505
The heat that friction generates can be discharged by heat release hole 516；Thus it promotes mainly auxiliary piston when piston moves downward and synchronizes downward fortune
Dynamic, to be compressed brake drum 505 on the disc brake rotor by fixing axle 513, brake disc drives brake drum 505 to rotate, and leads to
Crossing the comfortable brake force of brake drum 505 is the braking effect that brake disc undertakes a part, to reduce brake disc and brake block
The heat generated between 502 solves disc type brake heat and is concentrated in brake disc and brake block 502, frequently brakes when system
The excessively high problem for causing brake failure risk high of Moving plate temperature.
Step 3 when loosening the brake, promotes mainly piston block 507 and auxiliary piston block 511 is withdrawn in conjunction with shown in Fig. 1-6,
Auxiliary piston block 511 withdraws to pull sliding block 512 to move upwards by reset spring 503, is pulled and is braked by fixing axle 513
Roller 505 and braking disk detachment, auxiliary braking effect release；Featured piston block 507 pulls brake block 502 and brake disc when withdrawing
It is detached from, braking effect releases completely, so the design of whole device, good braking effect, a part of brake force are transmitted to outside, stops
Vehicle piece 502 and brake disc loss are reduced.
