Document Type and Number:
Japanese Patent JPH1089457
Kind Code:
A
Abstract:

To provide a method for shifting a twin clutch type transmission so that both of original and target gears can be arranged in the same transmission input shaft.

A twin clutch type transmission 10 is equipped with two transmission input shafts E1, E2 and one transmission driven shaft A, respectively. Each of friction clutches K1 and K2 is additionally installed in these transmission input shafts, and at a starting state, one side of both clutches transmits engine torque in a static frictional state, and the other side one is opened, and both of target and original gears are installed in the same one transmission input shaft. When this twin clutch transmission is shifted, an auxiliary gear installed in the other side shaft is used for generating a feeler torque, and a transmission ratio of this auxilairy gear is larger than those of the traget gear and the original gear.
