It is bonded with brake drum inwall, car deceleration and parking is realized by both rubbing actions.After completing braking, in brake chamber 10
Air pressure cut-out, brake shoe iron assembly 30 is pulled to initial position, separated with brake drum by air chamber push rod return, return spring 50,
Avoid phenomenon of dawdling.
Thus, the utility model replaces cam axle type brake to have lacked air chamber support, adjustment arm, convex with single wedge type wheel cylinder
The parts such as wheel shaft.The internal drive structure push rod assembly 21 of wheel cylinder assembly 20 and wedge shape top cylinder 22 directly coordinate, and wedge shape top cylinder 22 has
There is the effect from mediation amplification power：The gap of friction plate and drum is automatically adjusted, to make up gap caused by friction disc brake abrasion,
Manual adjustment gap is not needed, brake shoe iron assembly is maintained at brake drum gap in a stability range so that brake force
Square is stable.Braking ability and reliability greatly improve.
As shown in fig. 6, peep hole 61 is provided with dust blocking tray 60 and adjusts lyriform pore 62, by adjusting lyriform pore 62 to realize wheel cylinder assembly 20
Manual regulation.Lyriform pore 62 is adjusted to be located at the upper end of dust blocking tray 60, provided with two.Ratchet on just corresponding wedge shape top cylinder 22, is being filled
When car or maintenance, reached after being passed through with screwdriver 70 on the ratchet on the cylinder 22 of corresponding wedge shape top, wedge shape top cylinder 22 is stretched
The regulation of contracting amount, and then the gap of adjustable friction plate and wheel hub.Peep hole 61 is located at the middle-end of dust blocking tray 60, provided with four.With
In observation and the gap of measurement friction plate and wheel hub, and the abrasion condition of friction plate can be observed, be easy to change in time.
Dust blocking tray 60 is removably mounted on back-plate 40, can at any time be disassembled and be carried out clearing up dust and mud
It is husky.Dust blocking tray 60 is designed with peep hole and adjusts lyriform pore, can be realized with screwdriver 70 and wheel cylinder assembly 20 is adjusted manually.In entrucking and
During after-sales service, the gap of conveniently adjusted friction plate and drum.
As shown in Figure 4 and Figure 5, the connection of brake shoe iron assembly 30 and back-plate 40 of the present utility model, using complete floating
Formula structure, the hoof pin structure used different from tradition as shown in Figure 7, reduces two hoof pins and hoof lock locking apparatus, bottom
Plate bottom is opened mark structure and replaced by scotch, while cancels the hoof pin hole seat on shoes and two bushings.Tradition system as shown in Figure 7
Dynamic device connected mode needs to arrange hoof pin-and-hole position on back-plate, brake shoe iron arrangement hoof pin-and-hole, and with hoof pin by its two
Individual part is attached.The utility model uses full floating structure, increases locking groove and stopper slot, single reinforcement on back-plate 40
The afterbody of brake shoe iron assembly 30 of structure is fitted into groove.When braking, wheel cylinder assembly 20 opens brake shoe iron assembly 30, due to
The locking groove limitation brake shoe iron assembly 30 of the lower end of back-plate 40 moves up and down, can only be around its fulcrum, back-plate 40
The stopper slot limitation brake shoe iron assembly 30 at middle part can only move along the launch direction of wheel cylinder assembly 20, coordinate two return bullets up and down
The spring force of spring 50, prevent the bob of brake shoe iron assembly 30, ensure its perpendicularity, braking when friction plate completely with braking
Drum inwall fitting, improves braking ability and reliability.Using full floating structure, equally reduce assembly process, convenient for assembly, section
Save time, improve efficiency of assembling.The structure of back-plate 40 is changed, while significantly reduces the weight of bottom plate, realizes product light weight
Change.Full floating structure is convenient to disassembly in maintaining after sale.
Pneumatic drum brake specific implementation of the present utility model is as follows through experiment test, situation：Specification is 320 hydraulic pressure
Drum brake, hydraulic pressure are designed by 8Mpa, and braking moment is in 4000Nm or so, and the utility model is with pneumatic drum brake generation
For hydraulic drum brake, brake specification is similarly 320, with the use of 12# brake chambers and 0.6Mpa air pressure, braking moment
It can reach 6500Nm or so.40% is improved in terms of brake force, can meet the needs of more heavy－duty light truck, to promote city
The fast development of city's goods truck.
As shown in figure 8, the performance test data analysis through laboratory to different braking device, brake specification are all 410, make
With 30 cun of air chambers of same producer, can reach according to torque, wedge brake mechanical braking efficiency caused by contrast brake
90%, the mechanical braking efficiency of traditional S type cam axle type brakes as shown in Figure 7 can only achieve 70%.Wedge brake
Efficiency apparently higher than conventional cam shaft type brake.
Embodiment is replaced traditional in the case where guaranteeing to meet braking ability with punch welding single reinforcement formula shoes
The cast type shoes of QT450-10 materials, the more conventional like product of part is light by 30% or so, realizes part lightweight.If press city
Specification size is 320 conventional gas cam drum type brake on field, and single weight is about 30kg.And use the utility model list
Weight is about 20kg after individual brake, is calculated by light truck front-rear axle, and each car at least needs 4 brakes, and each car can mitigate
Weight 40kg.
Floating structure of the present utility model, to the surface pressure distribution of friction plate than more uniform so that the mill of friction plate
Damage situation is also than more uniform so that the thickness of friction plate can be thinned during design, after tested friction plate utilization rate is improved
25%, friction plate life.
As can be seen here, the utility model replaces camshaft structure compared with conventional brake using wheel cylinder assembly so that system
Dynamic device retro-speed faster, and lifts retardation efficiency, braking reliability lifting.Using full floating structure, brake shoe iron is changed
With the connected mode of back-plate, brake weight is significantly reduced, realizes product lightweight, and reduces assembly process, it is convenient
Assembling, improve efficiency of assembling.
