Title
(EN) REDUCTION MOTOR FOR DRUM BRAKE
(FR) MOTOREDUCTEUR POUR FREIN À TAMBOUR
Abstract
(EN)
A reduction motor for a parking brake mechanical actuator (7) of a drum brake comprising an electric motor (21) and a reduction gearbox (32), in which the electric motor (21) comprises an output shaft (24) extending along a first axis, the reduction gearbox (32) comprises an output shaft extending along a second axis, and in which the reduction motor also comprises at least one angle gear (44) between the electric motor (21) and the reduction gearbox (32) or at the output of the reduction gearbox (32), said angle gear (44) comprising a flat-wheel gear-pair comprising a pinion (25) and a flat gearwheel (34a), the pinion (25) being engaged with the output shaft (24) of the electric motor (21) and meshing with the flat gearwheel (34a) which is a part of the reduction gearbox (32).
(FR)
Motoréducteur pour actionneur mécanique (7) de frein de parking d'un frein à tambour comportant un moteur électrique (21) et un réducteur (32), dans lequel le moteur électrique (21) comporte un arbre de sortie (24) s'étendant selon un premier axe, le réducteur (32) comporte un axe de sortie s'étendant selon un deuxième axe, et dans lequel le motoréducteur comporte également au moins un renvoi d'angle (44) entre le moteur électrique (21) et le réducteur (32) ou en sortie du réducteur (32), ledit renvoi d'angle (44) comprenant un engrenage à roue plate comportant un pignon (25) et une roue dentée plate (34a), le pignon (25) étant en prise avec l'arbre de sortie (24) du moteur électrique (21) et engrenant la roue dentée plate (34a) qui est une partie du réducteur (32).
