Description

Technical Field

[0001] This utility model relates to the field of braking technology, and more specifically to a dual-control braking device. Background Technology

[0002] Braking devices all convert kinetic energy into heat energy through friction to achieve deceleration or stopping. For example, the automotive braking system converts the vehicle's kinetic energy into heat energy through the friction between the friction pads and the brake disc, ensuring driving safety. For example, a pneumatic brake assembly with publication number CN210760726U is disclosed in this utility model. The pneumatic brake assembly includes a frame, a rear axle assembly mounted on the frame, and a brake caliper connected to the braking device in the rear axle assembly. An air tank and an air compressor pump are installed on the frame and are connected to each other. An oil-air combination pump connected to the air tank is installed on the frame and is connected to the brake quick-release valve. A brake pedal connection connected to the oil-air combination pump is installed on the frame. An electronic booster vacuum pump connected to a vacuum booster is installed on the frame. This invention enables direct braking after air is cut off, preventing the vehicle from rolling due to insufficient handbrake engagement; this invention enables braking by simply pressing the brake pedal; this invention separates the brake and parking brake circuits, with the parking brake automatically engaging after air is cut off, effectively preventing brake failure.

[0003] Existing technology is inadequate: In actual use, pile drivers are heavy and have great inertia. When braking, only the rear wheels are braked, and the resistance generated during braking is limited, which cannot achieve effective braking. The braking distance is long, which affects traffic safety. Utility Model Content
