Document Type and Number:
Japanese Patent JP2004245418
Kind Code:
A
Abstract:
To provide a transmission device designed in the optimum condition in regard to running performance.
Each drive branched passage can operate by connecting a clutch so that a new gear stage can be connected in a drive branched passage which is not operated. The gear stage can be effectively shifted by shutting off the clutch on one side and connecting the clutch on the other side. Traction shift up of a parallel shift transmission device can be performed without interfering with an electronically controlled engine with regard to an operation condition specified in advance.
