Appeal 2006-2793
Application 10/829,536
On the other hand, said resilient
intermediate pressure means is not as stiff as a
direct connection between the screw mechanism
and the actuating member. This adapted stiffness
has the advantage that extreme loadings, which
have a certain transverse component or bending
moment, are not directly and fully transmitted
towards the screw mechanism. The resilient aspect
of the force transmission between screw
mechanism and actuating member makes these
transverse or bending loadings less severe or even
absent.
Rinsma 1:31 to 2:9.
As seen in Fig. 3, rotation of nut 22 causes axial translation of screw
24 (Rinsma 5:18-20). Screw 24 engages the head of piston 35 by means of
interposed pressure pad 36, 53 (Rinsma 5:27) and, optionally, a ceramic pad
55, which may be arranged between the pressure pad and the head of the
piston 35 to thermally insulate the thermal oil (Rinsma 6:13-15). Screw 24
is held non-rotatably, but slidably, with respect to piston 35 by nut/groove
connection 39, 39’ (Rinsma 5:25-26). Pressure pad 36, 53 is adapted to
accommodate misalignment between the axis of piston 35 and screw 24 that
might result from braking action in which brake pad 5 tilts somewhat
(Rinsma 5:31-33).
