An electromechanical actuator for a motor vehicle brake, comprising an electric motor absorbing a nominal rated current (In), a screw-and-nut movement converter including a screw with an axis (AX) extending in a longitudinal direction and a nut supported by the screw, and comprising at least one elastic return member for varying the resistance to forward motion in the longitudinal direction of an element being transferred between the nut and the screw at a predetermined position, in order to modify the nominal rating (In) of the current flowing through the motor while the element is being transferred to the predetermined position.

Electromechanical actuator for a vehicle brake with increased service life

A reduction motor for a parking brake mechanical actuator of a drum brake comprising an electric motor and a reduction gearbox, in which the electric motor comprises an output shaft extending along a first axis, the reduction gearbox comprises an output shaft extending along a second axis, and in which the reduction motor also comprises at least one angle gear between the electric motor and the reduction gearbox or at the output of the reduction gearbox, the angle gear comprising a crown gear-pair comprising a pinion and a crown gear, the pinion being engaged with the output shaft of the electric motor and meshing with the crown gear which is a part of the reduction gearbox.

Reduction motor for drum brake

A reduction motor for a parking brake mechanical actuator of a drum brake comprising an electric motor comprising an output shaft extending along a first axis, and a reduction gearbox comprising an output shaft extending along a second axis, in which the reduction gearbox, comprises stepped tangentially-meshing spur gears, each stepped gear comprising a gearwheel and a coaxial pinion, these being superposed on and secured to each other in terms of rotation, the stepped gears being mounted with the ability to rotate about mutually parallel axes.

Reduction gearbox for drum brake, offering significant conformability

The vehicle drum brake comprises a plate, at least one segment comprising a core and a brake lining, a spring able to keep the core of the segment in an axially balanced position, means for prestressing the spring wherein said means for prestressing the spring include stop means limiting the ability of the core of the segment to move axially.

Drum brake provided with a member for holding a brake segment

A motor vehicle drum brake () includes: two braking segments (A,B); an anchoring element () including two bearing surfaces (A,B) of two second ends () of the braking segments (A,B); a wheel cylinder () which, in a first 'simplex' operating mode, is suitable for transversally separating the adjacent first ends () of the segments (A,B); the anchoring element () including: a fixed body () wherein two sliding pistons (A,B) each carry a bearing surface (A,B); and elements () for separating the pistons (A,B) between an anchoring position wherein they abut against the body (), and a sliding position wherein the pistons (A,B) are separated to allow the sliding thereof during operation in so-called 'servo-dual' mode.
