Car is with two caliper disc type stoppers

The utility model provides a car is with two caliper disc type stoppers, it includes the hydraulic pressure master cylinder, oil duct, piston, friction disc in the upper and lower brake caliper of, upper and lower brake caliper, three -way valve, brake disc assembly, rim assembly, wheel hub bearing, wheel hub, knuckle, brake piping, upper and lower brake caliper installs on the knuckle. The utility model provides a pair of car is with two caliper disc type stoppers, the braking moment of production is proportional with hydro -cylinder hydraulic pressure, relatively current single disc brake, the braking moment increase is 2 times on the wheel for brake force also increases with braking efficiency in step, and braking distance and braking period reduce to single disc brake's half. Simultaneously, stopper braking efficiency receives coefficient of friction's influence less, and it is more stable to brake efficiency promptly to simple structure, the friction disc dismouting is changed easily, easy maintenance simple structure, heat -sinking capability is strong, and the ride comfort the during braking is good.
