2.2.2.1 First approach for determine the braking moment
If we know that :
P1 = CT.6 [N]
Where:
P1 [N] – Force on the main spring of the brake;
CT [N/m] – Theoretical elastic factor of the main spring of the brake;
8 [m] – Deformation of the main spring of the brake.
Braking moment will be:
(P – Po). µ. D. L
[Nm]
Mpri
L1
Where:
P1 [N] – Force in the main spring;
Po [N] – Force in the secondary spring;
H - theoretical friction factor between brake pad and drum;
D (m] – drum diameter;
L [m] – length of the first lever;
L1 [m] – length of the second lever.
