As described above, the transmission device itself is equipped with a plurality of pairs of sun gears and planetary gears, and is configured to change speed in multiple stages depending on which pair is selected to work effectively. Compared to a gear change mechanism that selects a pair of gears on separate shafts that mesh with the gears to change the speed, this type of transmission has the advantage of being easier to change gears and being more compact in structure. Since it has a single shaft, it is natural that the output can only be expected when the gears are changed by uniformly changing the internal transmission mechanism, and therefore it is applicable to work vehicles such as agricultural tractors. When attempting to do so, the steering device must be able to drive and shift, and the power take-off shaft for the connected working device must be driven at a constant speed regardless of the traveling speed.
Even if output is desired in two different transmission states,
If it is not possible to obtain the output of two systems corresponding to this, for example, as shown in Japanese Patent Publication No. 31-9763, the output of the side that is shifted by the transmission device is extracted,
It is necessary to transmit power by means separate from the transmission device, such as by extracting the output that is to be operated at a constant speed through a separate system without going through the transmission device. However, it was not possible to achieve sufficient simplification.
