YWZ13 Series Electro-Hydraulic Drum Brakes
The YWZ13 series drum brakes are available in multiple models to suit various braking torque requirements and installation conditions. Each model is configured with a matching Ed series electro-hydraulic thruster and offers different mechanical dimensions. Below is a summary of key parameters:
- Braking Torque Range
Each model provides a defined range of braking torque, for example:- YWZ13-200/E23: 100–200 Nm
- YWZ13-300/E80: 630–1000 Nm
- YWZ13-400/E121: 1000–2000 Nm
- YWZ13-500/E80: 800–1600 Nm
- This allows for flexible adaptation to different load conditions.
- Matching Electro-Hydraulic Thruster
The drive unit used is an Ed series thruster such as Ed23/5, Ed30/5, Ed80/6, or Ed121/6, selected based on the required thrust and stroke. - Setback Distance
Some models specify a setback distance (e.g., 0.7 mm for YWZ13-200/E23, 8.0 mm for YWZ13-300/E30), which is the distance the brake arms move when disengaged. - Key Installation Dimensions
A, B, C, D, E: Basic mounting widths and hole spacing (in mm) - d: Shaft or bolt hole diameter
- H / Hmax: Overall height or installation height range
- L, G1, G2, G3: Mounting flange distances
- hi, i, k, M, n: Lever arms, mounting holes, and structural limits
For instance:
YWZ13-300/E30:
A = 590 mm, B = 140 mm, C = 160 mm
D = 300 mm, d = 22 mm, E = 255 mm
H = 605 mm, Weight = 65 kg
YWZ13-500/E80:
A = 810 mm, B = 200 mm, C = 240 mm
D = 500 mm, d = 22 mm, E = 380 mm
H = 900 mm, Weight = 220 kg
Weight
The net weight varies by model and configuration:
From 32 kg for smaller models (YWZ13-200/E23)
Up to 220 kg for larger models (YWZ13-500/E80)
General Notes
Not all dimensional values are filled in for every model — actual configuration may depend on optional features or customer-specific requirements.
Dimensional consistency is based on JB/ZQ4388-1997 standard. For more precise dimensioning (e.g., hole positions or interface clearance), refer to CAD drawings or manufacturer’s detail sheet.
