Abstract: A continuously variable transmission steering mechanism of a tracked vehicle, comprising a differential (1), a right drive shaft (2), a left drive shaft (3), and a continuously variable transmission (4) used for adjusting the rotational speed of the right drive shaft (2) and that of the left drive shaft (3). A left half shaft (5) and a right half shaft (6) are connected on the differential (1). The right half shaft (6) of the differential (1) is linked to the right drive shaft (2). The right drive shaft (2) rotates to drive the right half shaft (6) of the differential (1) to rotate. The left half shaft (5) of the differential (1) is linked to the left drive shaft (3). The left drive shaft (3) rotates to drive the left half shaft (5) of the differential (1) to rotate. The rotational speed ratio of the right half shaft (6) of the differential (1) to the right drive shaft (2) is equal to the rotational speed ratio of the left half shaft (5) of the differential (1) to the left drive shaft (6). The employment of the continuously variable transmission steering mechanism of the tracked vehicle, by means of continuously and precisely adjusting the rotational speeds of the left and right half shafts of the differential via the continuously variable transmission (4), implements precise turning of tracks, thus increasing the safety of the tracked vehicle traveling at a high speed.

Abstract: In a continuously variable transmission, driving force from a drive source is transmitted via the path: first input switching mechanism→first input path→first countershaft→first pulley→endless belt→second pulley→second countershaft→first output path→second input shaft→first output switching mechanism→output shaft to thus establish a LOW mode. A large torque that is transmitted in the LOW mode passes through the first output switching mechanism, but since the second input shaft is relatively rotatably disposed on the outer periphery of the first input shaft and the first output switching mechanism is disposed on the second input shaft, it is possible to enhance the rigidity of the input shaft due to the double tube structure formed from the first input shaft and the second input shaft and to support the first output switching mechanism with high rigidity without carrying out special reinforcement.

Abstract: When neutral control is started by placing a CVT drive clutch in a semi-engaged state while a vehicle is decelerating in a state where a second power transmission path is established, a clutch mechanism that is semi-engaged in neutral control while the vehicle is decelerating is changed from the CVT drive clutch to a forward clutch before a stop of the vehicle, so it is possible to continue the neutral control until a stop of the vehicle. At a stop of the vehicle, a power transmission path is already changed to a first power transmission path that establishes a gear ratio (EL) higher than a highest gear ratio (γmax) that can be established by the second power transmission path. Thus, right after a stop of the vehicle, it is possible to execute idle stop control.
