Abstract:
(EN) Disclosed are a drum brake (201) and a vehicle (300). The drum brake (201) comprises a brake back plate (200), a brake drum (10), two brake shoes (20), an electric motor (30), a reciprocating motion mechanism (40), a drive body (80) and two ejector rods (90), wherein the brake shoes (20) are hinged to the brake back plate (200); the two ejector rods (90) are arranged at two sides of the drive body (80) and are located on the same straight line; one end of each of the ejector rods (90) abuts against the drive body (80), and the other end abuts against the corresponding brake shoe (20); the electric motor (30) drives, via the reciprocating motion mechanism (40), the drive body (80) to carry out reciprocating motion in a direction perpendicular to the ejector rods (90); and the drive body (80) pushes the two ejector rods (90) to synchronously move on the straight line in opposite directions, enabling the two brake shoes (20) to open.
(FR) L'invention concerne un frein à tambour (201) et un véhicule (300). Le frein à tambour (201) comprend une plaque arrière de frein (200), un tambour de frein (10), deux sabots de frein (20), un moteur électrique (30), un mécanisme de mouvement de va-et-vient (40), un corps d'entraînement (80) et deux tiges d'éjection (90); les sabots de frein (20) sont articulés sur la plaque arrière de frein (200); les deux tiges d'éjection (90) sont disposées sur deux côtés du corps d'entraînement (80) et sont situées sur la même ligne droite; une extrémité de chacune des tiges d'éjecteur (90) vient en butée contre le corps d'entraînement (80), et l'autre extrémité vient en butée contre le sabot de frein correspondant (20); le moteur électrique (30) entraîne, par l'intermédiaire du mécanisme de mouvement de va-et-vient (40), le corps d'entraînement (80) pour effectuer un mouvement de va-et-vient dans une direction perpendiculaire aux tiges d'éjection (90); et le corps d'entraînement (80) pousse les deux tiges d'éjection (90) à se déplacer de manière synchrone sur la ligne droite dans des directions opposées, permettant aux deux sabots de frein (20) d'être ouverts.
(ZH) 一种鼓式制动器(201)及车辆(300)。鼓式制动器(201)包括制动底板(200)、制动鼓(10)、两个制动蹄(20)、电机(30)、往复运动机构(40)、驱动体(80)、两个顶杆(90),制动蹄(20)铰接于制动底板(200),两个顶杆(90)设置在驱动体(80)的两侧且位于同一直线上,每个顶杆(90)的一端抵接于驱动体(80),另一端抵接于对应的制动蹄(20),电机(30)通过往复运动机构(40)驱动驱动体(80)沿垂直于顶杆(90)的方向往复运动,驱动体(80)推动两个顶杆(90)朝相反的方向在所述直线上同步运动,以使两个制动蹄(20)张开。
