Decision inputs
- Braking or clamp force
- Friction pair and lever arm
- Release travel and force
- Fail-safe state
- Cycles, temperature and contamination
APPLICATION SOLUTION
Spring-Applied Brakes and Power-Off Holding
Stored spring energy supplies braking or holding force and is released hydraulically, electromagnetically or mechanically.
ENGINEERING PROBLEM
The system must retain braking force during power loss or faults while meeting release travel and cycle-life requirements.
BOUNDARY
This page describes a decision pattern and does not promise size or performance for another operating condition.
Solution pattern
- Convert brake demand into an axial spring-force window
- Configure the stack for release travel
- Check fault state and wear compensation
- Define released and applied acceptance states
Key risks
- Friction-coefficient changes alter braking force
- Incomplete release can cause drag and heating
- Spring damage can compromise fail-safe capability
Verification plan
- Stack load-deflection test
- Brake torque or clamp-force test
- Release test at minimum actuation energy
- Retest after wear and thermal cycling
