Title:
The gearbox for vehicles
Document Type and Number:
Japanese Patent JP6122658
Kind Code:
B2
Abstract:
A power transmission mechanism interposed between an input shaft and an output shaft for transmitting torque of the input shaft to the output shaft, and the power transmission mechanism including gear mechanisms corresponding to each of gear stages respectively. A control device controls the power transmission mechanism to realize one of a first control mode, a second control mode and a third control mode selectively. The first control mode is a mode in which when a first gear stage of the gear stages is selected, the power transmission mechanism transmits the torque of the input shaft to the output shaft via only a first gear mechanism corresponding to the first gear stage. The second control mode is a mode in which when a second gear stage of the gear stages is selected, the power transmission mechanism transmits the torque of the input shaft to the output shaft via only a second gear mechanism corresponding to the second gear stage. The third control mode is a mode in which at the time of gear-shift from the first gear stage to the second gear stage, the power transmission mechanism circulates torque having a prescribed amount to the input shaft from the output shaft via the first gear mechanism while transmitting the torque of the input shaft to the output shaft. Thus, it becomes possible to reduce torque changed shock at the time of gear-shift in a transmission for vehicle which shifts gears between a first gear stage and a second gear stage.
