An accelerator pedal assembly that provides a hysteresis in pedal force- response upon actuation is provided. The accelerator pedal assembly includes a housing (32), an elongated pedal arm (22) terminating at one end in a rotatable drum (29) defining a curved braking surface (42), a brake pad (44) having a curved contact surface (70) substantially complementary to the braking surface (42) and a bias spring device (46) operably situated between the pedal arm (22) and the brake pad (44). The pedal arm (22) is rotatably mounted to the housing (32) such that the curved braking surface (42) rotates as the pedal moves. The brake pad (44) defines a primary pivot axis and is pivotably mounted for frictional engagement with the braking surface (42). The bias spring (46) serves to urge the contact surface (70) of the brake pad (44) into frictional engagement with braking surface (42) of the drum (29).
L'invention concerne un ensemble pédale d'accélérateur qui assure une hystérésis en réponse de force sur la pédale au moment de l'activation, comprenant une enceinte (32), un bras de pédale allongé (22) aboutissant à une extrémité à un tambour rotatif (29) qui définit une surface de freinage courbe (42), une plaquette de frein (44) à surface de contact courbe (70) sensiblement complémentaire par rapport à la surface de freinage (42) et un dispositif à ressort de contrainte à ressort (46) situé opérationnel entre le bras (22) et la plaquette (44). Le bras (22) est monté rotatif sur l'enceinte (32) de sorte que la surface de freinage courbe (42) tourne lorsque la pédale se déplace. La plaquette (44) définit un axe de pivot primaire et est montée pivotante aux fins de frottement avec la surface de freinage (42). Le ressort (46) pousse la surface de contact (70) de la plaquette (44) en frottement avec la surface de freinage (42) du tambour (29).
