Abstract
A force transmission device, tappet, and method of manufacture. The tappet may include a shaft portion for transmission of a thrust loading from an actuating member to a piston of a disc brake and a gear portion for transmission of rotary motion to the shaft. The gear portion may be formed as a separate piece from the shaft portion.
Claims16
A tappet comprising:
- a shaft portion for transmission of a thrust loading from an actuating member to a piston of a disc brake;
- and
- a gear portion for transmission of rotary motion to the shaft portion;
- wherein the gear portion is formed as a separate piece from the shaft portion, the gear portion is formed from a lower strength material than the shaft portion, and the shaft portion and the gear portion have complementary abutting surfaces in a circumferential direction so as to restrict relative rotation of the gear portion with respect to the shaft portion, wherein the complementary abutting surfaces are provided as complementary castellations on the shaft portion and the gear portion.
