Patent ID: 8317001

Claim:
A vehicle brake comprising: friction elements; a support member extending facing the friction elements for supporting at least one actuator; said at least one actuator subdivided into only two portions, that are a first portion and a second portion: wherein the first portion comprises a screw-and-nut system having one of a screw and a nut forming a first element and the other forming a second element of the screw-and-nut system, said first element being rotatable while said second element cooperates with an antirotation device so that rotation of the first element causes the second element to move linearly to selectively exert compression on the friction elements, said screw-and-nut system having a main axis defining a first axis of said first portion; wherein the second portion comprises a motor, said motor having a rotation axis defining a second axis of said second portion; said first portion being fitted on the support member and being removable as a whole from said brake, said second portion also being removable as a whole from said brake; said first portion and second portion operationally cooperating to transmit a rotary motion of the motor to said first element of the screw-and-nut system so that rotation of the motor causes linear motion of the second element of said screw-and-nut system, said first axis and said second axis being non-coaxial when said first portion and said second portion cooperate; wherein the support member is arranged so that: said second portion can be removed from the brake while said first portion remains in place on said support; and said first portion can be removed from the brake only when said second portion has been previously removed, wherein the support member is configured such that said first portion of the actuator is removable from the brake along a first direction, and said second portion of the actuator is removable from the brake along a second direction that is distinct and perpendicular from said first direction.
