Title
(EN) REDUCTION GEARBOX FOR DRUM BRAKE, OFFERING SIGNIFICANT CONFORMABILITY
(FR) MOTOREDUCTEUR POUR FREIN À TAMBOUR OFFRANT UNE CONFORMABILITE IMPORTANTE
Abstract
(EN)
A reduction motor for a parking brake mechanical actuator (7) of a drum brake comprising an electric motor (21) comprising an output shaft (24) extending along a first axis, and a reduction gearbox (32) comprising an output shaft extending along a second axis, in which said reduction gearbox (32), comprises stepped tangentially-meshing spur gears (34, 35, 36, 37, 38), each stepped gear comprising a gearwheel and a coaxial pinion, these being superposed on and secured to each other in terms of rotation, said stepped gears (34, 35, 36, 37, 38) being mounted with the ability to rotate about mutually parallel axes (AX34, AX35, AX36, AX37, AX38).
(FR)
Motoréducteur pour actionneur mécanique (7) de frein de parking d'un frein à tambour comportant un moteur électrique (21) comprenant un arbre de sortie (24) s'étendant selon un premier axe, et un réducteur (32) comporte un axe de sortie s'étendant selon un deuxième axe, dans lequel ledit réducteur (32) comporte des engrenages étagés (34, 35, 36, 38, 38) à engrènement tangentiel, chaque engrenage étagé comportant chacun une roue dentée et un pignon coaxiaux superposés et solidaires entre eux en rotation, lesdits engrenages étagés (34, 35, 36, 37, 38) étant montés mobile en rotation autour d'axes (AX34, AX35, AX36, AX37, AX38) parallèles entre eux.
