Document Type and Number:
Japanese Patent JP6550820
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power transmission device of a vehicle in which an excessively-large sound and vibration are not generated, and which is achieved in seamless shift-up and shift-down.SOLUTION: A transmission of this device comprises: "a first input shaft A2c to which a drive force of an engine E/G is transmitted via a clutch C/D"; "output shafts A3, A4 which output power to wheels of a vehicle"; and "a plurality of normal gear change stages (first speed a, second speed a, third speed, fourth speed, fifth speed and sixth speed) having synchronous mesh mechanisms". The transmission further comprises: "a second input shaft A2e which is connected to a drive output shaft A1 of the E/G not via the clutch C/D, and different from the first input shaft A2c"; and "one or a plurality of additional gear change stages (first speed b, second speed b) which have gear reduction ratios which are the same as those of a part or all of the normal gear change stages out of a plurality of the normal gear change stage, are different from the normal gear change stage, and do not comprise the synchronous mesh mechanisms".SELECTED DRAWING: Figure 1
