Abstract
(EN)
A brake using magnetorheological transmission and brake-by-wire comprises a motor (1), a transmission mechanism (20), and a floating caliper mechanism (11). The transmission mechanism (20) comprises a magnetorheological clutch (3), an electrorheological clutch or a magnetic particle clutch, a planetary gear train (20a), and a ball screw mechanism (20b). The ball screw mechanism (20b) comprises a ball (8), a ball screw (9), and a sleeve (10). The floating caliper mechanism (11) comprises a brake back plate (16), brake blocks (13; 15), a brake caliper (12), a brake disc (14), and a guide pin (18). The motor (1) is connected in series to the magnetorheological clutch (3). Output torque of the motor (1) transmitted by the magnetorheological clutch (3) undergoes speed reduction and torque enhancement as performed by the planetary gear train (20a), and then pushes the sleeve (10) in the ball screw mechanism (20b). The sleeve (10) drives and performs linear movement together with the brake back plate (16) fixedly connected thereto, and finally pushes the brake blocks (13; 15) to rub the brake disc (14) for braking. The magnetorheological transmission device is provided in the brake driven by the motor (1) and using brake-by-wire, such that an entire system has a higher response speed, a wide range of transmittable torque, and high brake safety, and can solve the problem of locked rotor of the motor (1) during extended periods of braking.

L'invention concerne un frein utilisant une transmission magnéto-rhéologique et un frein par câble, lequel frein comprend un moteur (1), un mécanisme de transmission (20) et un mécanisme d'étrier flottant (11). Le mécanisme de transmission (20) comprend un embrayage magnéto-rhéologique (3), un embrayage électro-rhéologique ou un embrayage à particules magnétiques, un train planétaire (20a) et un mécanisme de vis à billes (20b). Le mécanisme de vis à billes (20b) comprend une bille (8), une vis à billes (9) et un manchon (10). Le mécanisme à étrier flottant (11) comprend une plaque arrière de frein (16), des blocs de frein (13;15), un étrier de frein (12), un disque de frein (14) et une broche de guidage (18). Le moteur (1) est relié en série à l'embrayage magnéto-rhéologique (3). Le couple de sortie du moteur (1) transmis par l'embrayage magnéto-rhéologique (3) subit une réduction de vitesse et une amélioration de couple telles qu'exécutées par le train planétaire (20a), puis pousse le manchon (10) dans le mécanisme de vis à billes (20b). Le manchon (10) entraîne et effectue un mouvement linéaire conjointement avec la plaque arrière de frein (16) reliée à lui à demeure, et pousse finalement les blocs de frein (13;15) pour qu'ils frottent le disque de frein (14) afin de réaliser le freinage. Le dispositif de transmission magnéto-rhéologique est disposé dans le frein entraîné par le moteur (1) et à l'aide d'un frein par fil, de telle sorte qu'un système tout entier présente une vitesse de réponse plus élevée, une large plage de couple transmissible, et une sécurité de freinage élevée, et peut résoudre le problème du rotor du moteur bloqué (1) pendant des périodes de freinage prolongées.
