Drive train for a wheeled vehicle and method of controlling same.

摘要

The present invention is related to a drive train of a wheeled vehicle having an engine and at least one driving wheel and a method for controlling the drive train. The present invention provides a drive train of a wheeled vehicle having an engine and at least one driving wheel, the drive train essentially composed of; (a) a first clutch means (7) connected to the engine for receiving driving force therefrom and outputting the driving force as varying a transfer ratio therebetween according to an operation of a driver; (b) a transmission (3) connected to the first clutch means for receiving the driving force therefrom and outputting the driving force as varying a rotational speed thereof; and (c) a second clutch means (10) connected to the transmission for receiving the driving force therefrom and transmitting the driving force to the driving wheel as automatically varying a transfer ratio therebetween according to a rotational frequency of the driving force outputted by the transmission. The present invention also provides a method for controlling a drive train of a vehicle having an engine and at least one driving wheel, the drive train comprising a first clutch means (7) connected to the engine for receiving driving force therefrom and outputting the driving force; a transmission (3) connected to the first clutch means for receiving the driving force therefrom and outputting the driving force; and a second clutch means (10) connected to the transmission for receiving the driving force therefrom and transmitting the driving force to the driving wheel, the method essentially composed of the steps of; (a) setting a transfer ratio at the first clutch means (10) according to an operation of a driver; (b) automatically setting a transmission ratio at the transmission; and (c) automatically setting a transfer ratio at the second clutch means (10) according to a rotational frequency of the driving force outputted by the transmission (3).
