摘要： In a dog clutch-type speed change device (50) of a dog clutch-type automatic transmission including a clutch (44) that controls transmission of a torque from a motive power source (45) to a main shaft, a transmission (48) that switches gears, a motive power source-torque adjustment device (80) that adjusts the torque of the motive power source (45) when a speed change is performed, and a control device (90) that controls the motive power source-torque adjustment device (80), when changing a speed, the control device (90) reduces the torque of the motive power source (45) while the clutch (44) is in a fully connected state or a partially connected state and dogs are in an engaged state, increases the torque of the motive power source (45) that has decreased from disengagement until engagement and while the clutch (44) has been in the fully connected state or the partially connected state, and reduces the torque of the motive power source (45) again while the clutch (44) is in the fully connected state or the partially connected state so as to eliminate partial engagement of the dogs when they are engaging during a period in which the motive power source (45) is outputting an increased torque.

摘要： In a transmission structure according to this invention, speed change ratios of input side first and second transmission mechanisms (50(1)-(2)) are set so that the rotational speed of a planetary second element (38) is same when an HST output is set to a second HST speed in a first transmission state and when a second transmission state is engaged, and the rotational speed of a planetary first element (36) is same when the HST output is set to the second HST speed in the second transmission state and when the first transmission state is engaged. The speed change ratios of output side first and second transmission mechanisms (70(1)-(2)) are set so that the rotational speed developed in a speed change output shaft (45) when the HST output is set to the second HST speed is same in the first and second transmission states.

摘要： A control value is corrected and learned based on a difference angle Δϕ between a drum shaft conversion spindle integration angle ϕs obtained by converting a detected spindle angle detected by a spindle angle sensor 78 into a drum angle and a detected drum angle ϕd detected by a drum angle sensor 89, over a predetermined learning time T from when the shift motor 61 is driven, and a drive engagement portion 83d of a shift driven gear 83 reduces the play angle to abut on a driven engagement portion 82d of a drum center 82 to accompany the driven engagement portion 82d. In this manner, rotation of a shift drum 80 can be accurately controlled by the shift motor 61, while the number of components of a variable speed drive mechanism 60 is reduced.
