THRUSTER DISC BRAKES

 

1.0 MD Series Thruster Disc Brakes Models

2.0 Principles of Operation

 

 

THRUSTER This is an electro-mechanical hydraulic actuator which is used as the principal means of brake release.

FS = Spring Force

FC = Clamping Force

FB = Braking Force = 2 x FC x µ

Nominal values of µ (Average friction factor of standard material combination)

µS STATIC = 0.4

µD DYNAMIC = 0.35
