작동 원리
The YWZ8 series electric hydraulic drum brake operates using hydraulic power to generate braking force and a drum-based mechanism to stop motion. Here’s how it works:
- Hydraulic Drive: Hydraulic oil is pumped through a control valve into the hydraulic cylinder of the brake. For example, in the YWZ8-200/E23, the hydraulic system generates enough force to apply the friction pads to the drum, creating the necessary braking torque of 135-200 Nm.
- Drum Braking: In this braking system, the friction pads, activated by hydraulic pressure, press against the rotating drum. The YWZ8-300/E30, with a braking torque of 200-320 Nm, ensures smooth and reliable stopping power even under high loads.
- Clearance Adjustment: The brake’s clearance, such as the 0.7 mm clearance in the YWZ8-200/E23, ensures optimal contact between the friction pads and the drum. Adjusting the clearance is crucial to maintain braking performance and prevent excessive wear.
