Abstract
There is provided an apparatus for applying a braking force to a brake disc using a brake pad. The apparatus comprises a lever configured to rotate about a first fulcrum, and a pressing member attached to said lever and for urging a brake pad against a brake disc. A component is arranged and configured to ensure that said pressing member has a circular translational movement upon rotation of said lever, and a rotatable input member is configured to rotate a first member. In use, rotation of said first member causes movement of an actuating member along an first axis (A), and said axial movement of said actuating member causes said lever to rotate about said first fulcrum for applying a braking force to said brake disc.
Claims15
An apparatus for applying a braking force to a brake disc using a brake pad, comprising:
- a lever configured to rotate about a first fulcrum;
- a pressing member attached to said lever and for urging a brake pad against a brake disc;
- a link member attached to said pressing member and configured to rotate about a second fulcrum in such a manner that said brake pad remains substantially parallel to said brake disc while said lever rotates about said first fulcrum;
- and
- a rotatable input member configured to rotate a first member, wherein, in use, rotation of said first member causes movement of an actuating member along an first axis (A), and said axial movement of said actuating member causes said lever to rotate about said first fulcrum for applying a braking force to said brake disc.
An apparatus for applying a braking force to a brake disc using a brake pad, comprising:
- a lever configured to rotate about a first fulcrum;
- a pressing member attached to said lever and for urging a brake pad against a brake disc;
- a resilient member attached to or associated with said lever and configured to urge the pressing member towards a brake disc;
- and
- a rotatable input member configured to rotate a first member, wherein, in use, rotation of said first member causes movement of an actuating member along an first axis (A′), and said axial movement of said actuating member causes said lever to rotate about said first fulcrum for applying a braking force to said brake disc.
A method of applying a braking force to a brake disc using a brake pad, the method comprising rotating a lever about a first fulcrum, wherein said lever is attached to a pressing member for urging said brake pad against said brake disc, wherein either:
- a link member is attached to said pressing member and is configured to rotate about a second fulcrum in such a manner that said brake pad remains substantially parallel to said brake disc while said lever rotates about said first fulcrum;
- or
- a resilient member is attached to or associated with said lever and is configured to urge the pressing member towards a brake disc upon rotation of said lever;
- and the method further comprises:
- rotating a first plate using a rotatable input member, wherein rotation of said first plate causes axial movement of an actuating member, and axial movement of said actuating member causes said rotation of said lever for applying a braking force to said brake disc.
