Electromechanical actuator for a vehicle brake, the vehicle brake including such an actuator, and a method of maintaining such an actuator

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 being subdivided into:
• a first portion comprising 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;
• a second portion including 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 said first portion of the actuator is removable from the brake along a first assembly path, and said second portion of the actuator is removable from the brake along a second assembly path that is distinct from said first assembly path;
• wherein said first assembly path extends in a plane perpendicular to a longitudinal axis of said brake, and the second assembly path extends in a direction parallel to said longitudinal axis of said brake;
• and
• wherein said support member defines a fork between which said first portion is engaged following said first assembly path, said support member defining a hole into which said second portion is engaged following said second assembly path, said second portion having an output shaft projecting therefrom and penetrating into said first portion.
