Title
(EN) FRONT WHEEL ENERGY RECOVERY SYSTEM
(FR) SYSTÈME DE RÉCUPÉRATION DE L'ÉNERGIE D'UNE ROUE AVANT
Abstract
(EN)
A kinetic energy recovery system ("KERS system") and motorcycle equipped with the same is disclosed. The KERS system may be mechanical, hydraulic, or a combination thereof. In an embodiment, motorcycle includes a rear wheel, an electric motor, a motor shaft, and a front wheel equipped with a wheel hub that includes a sprag clutch. The motor shaft can be fitted with a motor drive sprocket that drives a jackshaft chain that in turn drives a jackshaft input sprocket that is fitted to the jackshaft. Jackshaft input sprocket may be installed in conjunction with a sprag clutch that allows the rear wheel to free wheel during coasting while the front wheel KERS system is engaged. The motor harvests kinetic energy from the front wheel without simultaneously powering the rear wheel while the use of a geared dead zone allows the front and rear wheels to not lock together to improve safety.
(FR)
La présente invention concerne un système de récupération de l'énergie cinétique (« système KERS ») et une moto équipée de ce système. Le système KERS peut être mécanique, hydraulique ou une combinaison des deux. Selon un mode de réalisation, une moto comprend une roue arrière, un moteur électrique, un arbre de moteur et une roue avant équipée d'un moyeu de roue comportant un embrayage à roue libre. L'arbre de moteur peut être pourvu d'un pignon d'entraînement de moteur qui entraîne une chaîne d'arbre intermédiaire entraînant à son tour un pignon d'entrée d'arbre intermédiaire monté sur l'arbre intermédiaire. Le pignon d'entrée d'arbre intermédiaire peut être installé conjointement avec un embrayage à roue libre qui permet à la roue arrière d'être en roue libre lors d'une marche en roue libre tandis que le système KERS de roue avant est enclenché. Le moteur récupère l'énergie cinétique provenant de la roue avant sans alimenter simultanément la roue arrière alors que l'utilisation d'une zone morte à engrenages permet aux roues avant et arrière de ne pas se bloquer en même temps afin de renforcer la sécurité.
