3.1.12 Mounting MDA 14 & 21
3.1.13 Draining of Brake cylinder
Example: MDA 1 has a static braking torque of 95 000 Nm (70 000 lbf·ft), when the brake is not
under pressure and
µ
= 0,1.
Assume that the pressure in brake cylinder drain is 1,5 bar / 1,75 psi. The diagram shows that
the actual brake torque (M
act
) corresponds to only 90% of M
max
.
Motors with SPECIAL
brakes may have different
working operation. Please
make sure that you check
the
Ordering code
on
your brake.
The Diagram 3., shows the falling static braking torque 95 000 Nm (70 000 lbf·ft) M
max
for increa-
sing pressure in the brake cylinder drain.
Back pressure in brake cylinder drainage line.
Diagram 3.2
The brakes, MDA 14 and MDA 1 are mounted to the bracket with M0 (strength class 10.9).
Tightening torque 540 Nm (398 lbf·ft). Inside of the brake, the spline shaft shall be greased with
Texaco Multi fac EP.
