  • the one-way flywheel 8 on the right side rotates counterclockwise to power output, so that the power system on the right side has power output.
  • the utility model comprises a vehicle body, a front wheel, a rear wheel and a driving system.
  • the vehicle body comprises a power lever and a body bracket.
  • the body bracket is provided with an upper power shaft, a front power shaft and a rear power shaft, and the power lever is arranged on the upper power shaft.
  • the driving system includes a power system including an eccentric wheel and a gear transmission system, the eccentric wheel is disposed on the front power rotating shaft, and the front power rotating shaft is driven and connected through the gear transmission system
  • the power lever is drivingly connected to the eccentric wheel, and the rear wheel is disposed on the rear power shaft.
  • the power lever drives the eccentric to rotate counterclockwise
  • the eccentric wheel drives the front power shaft to rotate counterclockwise.
  • the front power shaft is driven by the gear transmission system, and the power shaft rotates counterclockwise.
  • the rear power shaft drives the rear wheel to rotate counterclockwise to reach the power.
  • the purpose of the output Through the use of the eccentric wheel, the speed-shifting scooter is labor-saving, the shifting process is simple, and the stroke angle of the pedaling is changed to achieve different speeds, and the demand for the uphill power and the flat ground speed is met.

Abstract

La présente invention se rapporte à un scooter à changement de vitesse, qui comprend un corps de véhicule, une roue avant (1), une roue arrière (2) et un système d'entraînement. Le corps de véhicule comprend un levier de puissance (3) et un support (4) de corps ; le support de corps est doté d'un arbre de puissance rotatif supérieur (13), d'un arbre de puissance rotatif avant (14) et d'un arbre de puissance rotatif arrière (15), et le levier de puissance (3) se situe sur l'arbre de puissance rotatif supérieur (13) ; le système d'entraînement comprend un système de puissance et un système de retour, le système de puissance comprenant une roue excentrée (7) et un système de transmission par engrenage ; la roue excentrée (7) se situe sur l'arbre de puissance rotatif avant (14), l'arbre de puissance rotatif avant (14) étant relié à l'arbre de puissance rotatif arrière (15) et entraînant ce dernier par l'intermédiaire du système de transmission par engrenage ; le levier de puissance (3) est relié à la roue excentrée (7) et entraîne cette dernière ; et la roue arrière (2) se situe sur l'arbre de puissance rotatif arrière (15). A l'aide de la roue excentrée, rouler en scooter à changement de vitesse permet d'économiser du travail et il est simple et facile d'effectuer un changement de vitesse, et on répond aux exigences pour une bonne puissance en montée et une vitesse élevée sur le plat.
