Application 10/869,144
transforms the translational force into rotary movement of
transmission sleeve 9 (Figs. 1, 2 and 5, 6).
4. Appellant’s electric motor 3 rotates its drive shaft 4 to provide
rotary movement, which is transmitted, via coupling 5, coupling
shaft 6, gear 7, planet gear 8, and intermediate gear 10, to thrust
rod gears 11 of thrust rods 12. The thrust rods 12 transform rotary
movement of thrust rod gear 11 into linear movement of a part
connected to a first disc brake pad 13 at one side of brake disc 2
(Specification [00017] – [00019]). Accordingly, in Appellant’s
invention, the thrust rods 12 (or single thrust rod in the third
embodiment) are the “force transmission mechanism” that
transforms rotary movement provided, via a series of gears, by
both the elasticity spring and the electric motor into a linear or
translational brake applying movement.
5. Wolfsteiner’s motor 106 provides rotary movement at its output
shaft 108, which is engaged by toothed belt 110, which in turn is
engaged by pinion 112. Thus, the rotary movement of output shaft
108 is transmitted to pinion 112. The rotary movement of pinion
112 is then transmitted and ultimately converted to linear motion
of cover 120 by a series of sleeves, spindles, and nuts (Wolfsteiner
‘477, col. 5, l. 3 to col. 6, l. 14).
6. Wolfsteiner’s spring 14’ provides linear movement, via ring-
shaped slide 16’, interior sleeve 20’, and interior bush 66’, to cover
120 (Wolfsteiner ‘477, col. 5, ll. 27-32).
7. Translational movement of Wolfsteiner’s cover 120 causes angular
and translational movement of brake lever 121, which in turn acts
