Abstract
(EN)
Disclosed is a disc brake, comprising a brake caliper (10), a brake disc (20), a first brake pad (31), an electric motor (40), a reducer (50) and a screw rod mechanism (60), wherein the electric motor (40) is an external rotor motor; a stator (41) of the electric motor (40) is provided with a cavity (411) extending in an axial direction; the screw rod mechanism (60) comprises a screw rod (61) and a nut (62) sheathed onto the screw rod (61); the screw rod (61) passes through the cavity (411); and a rotor (42) of the electric motor (40) drives, via the reducer (50), the screw rod (61) to rotate, so that the nut (62) moves axially along the screw rod (61), thus pushing the first brake pad (31) to move to press the brake disc (20). A vehicle is further disclosed.

L'invention concerne un frein à disque, comprenant un étrier (10) de frein, un disque (20) de frein, un premier patin (31) de frein, un moteur électrique (40), un réducteur (50) et un mécanisme de tige de vis (60), le moteur électrique (40) étant un moteur à rotor externe ; un stator (41) du moteur électrique (40) est pourvu d'une cavité (411) s'étendant dans une direction axiale ; le mécanisme de tige de vis (60) comprend une tige de vis (61) et un écrou (62) gainé sur la tige de vis (61) ; la tige de vis (61) traverse la cavité (411) ; et un rotor (42) du moteur électrique (40) entraîne en rotation la tige de vis (61), par l'intermédiaire du réducteur (50), de sorte que l'écrou (62) se déplace axialement le long de la tige de vis (61), amenant ainsi le premier patin (31) de frein à se déplacer pour presser le disque (20) de frein. L'invention concerne en outre un véhicule.
