  • the present invention relates to a two-wheeled vehicle. More particularly, the present invention relates to mounting of a pressure control unit of a braking assembly on the two-wheeled vehicle.
  • Conventional braking systems in two-wheeled vehicles involves independent actuation of a front wheel brake and a rear wheel brake. While a front brake actuating means for the front wheel brake is typically provided on a handlebar of the two-wheeled vehicle, a rear brake actuating means for the rear wheel brake is typically provided either on the handlebar or in the form of a foot pedal on a vehicle frame.
  • the conventional braking systems typically involves certain risks associated with the safety of the two-wheeled vehicle. For example, if only the front wheel brake is applied, the rear wheel tends to lift off and the vehicle faces the risk of being toppled. The front wheel may also face the risk of skidding.
  • the contemporary braking system comprises a pressure control unit that controls a brake fluid pressure and a brake system such as a disc brake system, which includes master cylinders, connecting hoses and calipers for the front wheel and the rear wheel.
  • the pressure control unit distributes the braking force between the front wheel brake and the rear wheel brake, on actuation of either the front brake actuating means (e.g. a brake lever) or the rear brake actuating means (e.g. a brake pedal), based on different vehicle parameters.

Abstract

La présente invention se rapporte à un véhicule à deux roues (10) avec un ensemble frein présentant une unité de commande de pression (43). Le véhicule à deux roues (10) comprend un tuyau de tête (12) et un tube principal (13) s'étendant vers l'arrière à partir du tuyau principal (12). Le tube principal (13) comprend une première section (13a) et une seconde section (13b). La première section (13a) s'étend vers l'arrière à partir du tuyau de tête (12). La seconde section (13b) s'étend vers l'arrière et vers le bas à partir de la première section (13a). L'ensemble frein comporte une unité de commande de pression (43) apte à commander une pression pour une opération de freinage entre une roue avant (21) et une roue arrière (35) du véhicule, l'unité de commande de pression (43) étant montée sur la seconde section (13b) du tube principal (13).
