この考案は、圃場内で各種の農作業を行なわせ

るものである。[Detailed Description of the Invention] This invention relates to a transmission for an agricultural tractor or the like that performs various agricultural tasks in a field.
農用トラクタ等のトランスミツシヨンにおい
て、その変速段数を高めるためには、２組の変速

つた不都合がある。 In the transmission of agricultural tractors, etc., in order to increase the number of gears, two sets of transmissions are connected in series, but these two sets of transmissions are generally installed inside the transmission case of agricultural tractors, etc. They are arranged in front and behind each other. However, when two sets of transmissions are arranged one behind the other in this way, there is a disadvantage that the longitudinal length of the transmission case, and therefore the overall length of the machine body, becomes correspondingly longer.
そこで、同不都合を解消すべく、直列接続され

度に低くならざるを得ないのである。 Therefore, in order to solve this problem, it is conceivable to install two sets of transmissions connected in series one above the other in the transmission case of an agricultural tractor, etc., but in this case, the bottom of the transmission case The height of the transmission case above the ground, which is the distance between the ground and the ground, becomes lower, which is unfavorable in terms of workability in fields. In other words, the installation height (level) of the main shaft or input shaft, which is installed inside the transmission case and is driven to rotate by receiving input from the engine, is determined to be a substantially constant level due to the arrangement of the engine and main clutch. , and if the structure is such that the first set of transmissions and the second transmission set are sequentially installed below such a main shaft or input shaft, the level of the bottom of the transmission case may be too low. It has no choice but to be.

To provide a new transmission for an agricultural tractor, etc., which has transmissions arranged vertically inside the vehicle, which can increase the ground clearance of the transmission case, and which is compact as a whole. .

At the same time, a hollow transmission shaft is loosely fitted onto the main shaft over a certain length of the main shaft, and the transmission gears in which the main shaft and the first intermediate transmission shaft are respectively fixed to both shafts are meshed with each other. In addition, by meshing the transmission gears fixed to the hollow transmission shaft and the second intermediate transmission shaft, respectively, the hollow transmission shaft and the second intermediate transmission shaft are interlocked and connected, and the first intermediate transmission shaft and the hollow transmission shaft are connected to each other. A first transmission device is disposed between the two intermediate transmission shafts, and a second transmission device is disposed between the second intermediate transmission shaft and the output shaft, respectively.
