  • the brake arm force transmitting unit (194) transmits the brake operating force to the rear brake arm (146) of the rear brake unit (144), thereby actuating the rear brake unit (144) to decelerate the rear ground engaging member (111).
  • the outer sheath (210) of the second force transmitting unit (154) is disposed between the arm block (216) of the support link assembly (170) and the support body of the front brake unit (142)
  • forward movement of the second force transmitting unit (154) sandwiches the outer sheath (210) between the support body and the arm block (216), thereby generating a reaction pull of the inner wire (212) coupled to the front brake arm (148) of the front brake unit (142).
  • the reaction pull of the inner wire (212) actuates the front brake unit (142) to decelerate the front ground engaging member (106).

  • the support link assembly (170) comprises the support link (172) and the arm block (216).
  • the support link (170) is coupled to each of the swing arm (120) and the arm block (216) which is operatively coupled to the first force transmitting unit (152), the second force transmitting unit (154), and the brake arm force transmitting unit (194).
  • the support link (172) rotatably coupled to the arm block (216) reduces or eliminates the vibrations occurring in the first force transmitting unit (152), the second force transmitting unit (154), and the brake arm force transmitting unit (194), thereby reducing or eliminating the chances of failure of the speed deceleration system (140).
  • the support link (172) eliminates the noise generated due to the vibrations occurring in the speed deceleration system (140).
  • the support link assembly (170) comprises a biasing member (300).
  • the biasing member (300) is configured to reduce the vibration occurring within the speed deceleration system (140) and also restore the brake actuating unit (150) to its rest position once the rider of the vehicle (100) stops treading on the brake actuating unit (150).

Abstract

La présente invention concerne un véhicule (100). Le véhicule (100) comprend une ossature de caisse (102), un bras oscillant (120) et un système de décélération de vitesse (140). Le système de décélération de vitesse (140) comprend une unité de frein avant (142), une unité de frein arrière (144), un dispositif de distribution (200), une unité d'actionnement de frein (150), un ensemble de liaison de support (170), une première unité de transmission de force (152) fonctionnellement couplée à l'unité d'actionnement de frein (150) et à l'ensemble de liaison de support (170), une seconde unité de transmission de force (154) fonctionnellement couplée à l'unité de frein arrière (144) et au dispositif de distribution (200). L'ensemble de liaison de support (170) maintient de façon pivotante la première unité de transmission de force (152) et la seconde unité de transmission de force (154) au bras oscillant (120).
