本考案は、走行変速にかかわらず作業機に所定
回転数の動力を伝達する作業車の動力取出構造に
関する。[Detailed Description of the Invention] The present invention relates to a power extraction structure for a working vehicle that transmits power at a predetermined rotational speed to a working machine regardless of the traveling speed change.

力を伝達するに当たつて、従来は、第３図に示す
ように、入力軸S1と一体回転するギアGbに常時
咬合するギアGaを備えた動力取出軸１０を設け
ていた。 In order to transmit power at a predetermined rotational speed to a working machine regardless of the traveling speed, conventionally, as shown in Fig. 3, a gear Ga is provided that is always engaged with a gear Gb that rotates integrally with the input shaft S1 . A power take-off shaft 10 was provided.

めに、変速装置が複雑化すると共に大型化する欠
点があつた。 However, the power take-off shaft 10 is connected to the transmission case M.
In order to extend it to the outside, it must be placed in a position where it does not interfere with the intermediate transmission shaft S to the travel transmission, and a gear Ga dedicated to power extraction must be provided, which makes the transmission more complicated. There was a drawback to increasing the size.

した点にあり、その作用・効果は、次の通りであ
る。 The characteristic configuration of the present invention is that an intermediate transmission shaft for transmitting power to a traveling transmission in which a third gear and a fourth gear are loosely fitted is arranged parallel to an input shaft to which the first gear and the second gear are fixed, The first gear and the third gear are engaged with each other, and the second gear and the fourth gear are engaged with each other via a reversing gear provided on a rotating shaft different from the input shaft and the intermediate transmission shaft, and , a shift device is provided between the third gear and the fourth gear to selectively integrally connect the third gear and the fourth gear to the intermediate transmission shaft, and the power from the input shaft is transferred to the intermediate transmission shaft. The transmission is configured such that a state is transmitted from a first gear to the intermediate transmission shaft in a forward rotation state via a third gear, and a state is transmitted from a second gear to the intermediate transmission shaft in a reverse rotation state via a reverse rotation gear and a fourth gear. In a certain work vehicle, the rotating shaft of the reversing gear is extended and also used as a power take-off shaft, and its functions and effects are as follows.

を大巾に軽量小型化し得るに至つた。 In other words, since the reversing gear shaft that is originally provided in the transmission structure to the traveling transmission is used as the power take-off shaft, the gear dedicated to power take-off in the conventional configuration can be omitted, and it is originally a support for the reversing gear. Since the shaft is placed in a position where it does not interfere with the intermediate transmission shaft to the traveling transmission, by using the power take-off shaft as its support shaft, the space occupied by the power take-off shaft can also be saved. As a result, the power extraction structure can be greatly simplified, and as a result, the transmission can be significantly reduced in weight and size.
