The wet disk type braker of this heavy type mining automobile adopts one end of rotary friction pad to adopt stopping brake piston and the other end to adopt the structure of parking braking piston, and control respectively by driving oil-collecting hole and parking oil-collecting hole, thereby realized this break, having the functions such as service brake, hand braking, stopping brake, parking braking, emergency braking, dry moist road surface braking and fluid power deceleration, is to ensure that full car loads the key of gross mass traffic safety.
Adopted complex spring as return spring, its elastic force is large simultaneously, and active force is strong, thereby guarantees the stationary performance of parking braking.
The inner circumference of driving wheel is connected with seal holder ring by seal assembly, in seal ring with outer week, drive hub is set, thereby can, by the application's integral installation at rear axle tube two ends, make the effect of braking better.
Accompanying drawing explanation
Fig. 1 is the wet disc-like brake structure schematic diagram of heavy mine truck.
Embodiment
As shown in Figure 1, a kind of heavy type mining automobile disk type braker that wets, excircle at driving wheel 46 is provided with rotary friction pad composition 29, the excircle of rotary friction pad composition 29 is provided with brake disc housing 25, an end face at rotary friction pad composition 29 is provided with the stopping brake piston 31 with annular boss, the interior edge face of brake disc end cap 40 is provided with annular groove, the annular boss sealing of stopping brake piston 31 is plugged in brake disc end cap 40, brake disc end cap 40 is flexibly connected with brake disc housing 25 simultaneously, in brake disc end cap 40, be provided with ejector pin 32, ejector pin 32 one end are connected with Returnning spring 36 by baffle plate 34, the other end of ejector pin 32 is connected with stopping brake piston 31, other end at rotary friction pad composition 29 is provided with parking braking piston 23, in the exterior edge face of parking braking piston 23, by return spring group 20, is connected with spring flap 14, and spring flap 14 is located by locating stud 19 simultaneously, and is connected with brake disc housing 25, the inner circumference of spring flap 14 and driving wheel 46 are tightly connected by black box 50, the excircle of parking braking piston 23 is provided with two seals circle, on break end cap 40, be respectively equipped with parking oil-collecting hole 6 and driving oil-collecting hole 7, on brake disc housing 25, be provided with the oil circuit communicating with parking oil-collecting hole 6, the oil pressure in parking oil-collecting hole enters in the cavity between spring flap 14 and parking braking piston 23 by the space of two seals circle, the oil circuit of driving oil-collecting hole 7 communicates with stopping brake piston 31 annular boss upper-end surfaces.
