The brake unit is the core execution component of the brake system. It has a variety of types, mainly according to the working principle, structural form and application scenario. The following are common types and characteristics:
I. Classification by working principle
Friction Brake Unit
Disc brake: through the brake clamp clamping rotating brake disc generates friction, good heat dissipation, fast response, widely used in passenger car front wheels.
Drum brake: the brake hoof expands outwards to press the inner wall of the brake drum, the braking force is large but the heat dissipation is poor, mainly used in rear wheels or commercial vehicles.
Belt brake: using the brake belt to tighten the rotating parts, the structure is simple but the braking torque is large, common in industrial equipment.
Non-Friction Brake Unit
Magnetic powder brake: generates resistance through magnetic powder magnetization, small volume, precise control, suitable for precision equipment.
Magnetic vortex brake: using electromagnetic induction vortex effect brake, no mechanical wear, mainly used in high-speed trains.
Water vortex brake: through fluid resistance braking, suitable for ships or heavy machinery.
Classification by Structural Form
Clamp disc brake: fixed brake clamp, brake disc rotation, divided into fixed clamp and floating clamp, the latter is more widely used.
All-disc brake: the friction element is a steel disc with a large but large braking force for heavy vehicles.
Internal hoof type brake: the brake hoof expands inwards, compact structure, common in engineering machinery.
Classification by drive
Hydraulic brake unit: pressure transmission through the brake fluid, responsive, is the main configuration of passenger cars.
Air pressure brake unit: using compressed air drive, braking force is large, suitable for commercial vehicles.
Electric brake unit: integrated motor drive, fast response, mainly used in new energy vehicle energy recovery system.
Special Application Types
Renewable brake units: New energy vehicles reverse power generation through motors, converting kinetic energy into electrical energy storage.
Emergency braking unit: enabled when the main brake fails, the braking force is weak but can ensure the basic safety.
The choice of different types of brake units requires comprehensive consideration of factors such as braking force requirements, heat dissipation conditions and costs.
