本考案は、エンジンからの出力を前車輪と前部
動力取出軸とに各別の伝動軸を介して伝達し、こ
れらを駆動するように構成してある乗用トラクタ
の伝動部構造に関する。[Detailed description of the invention] This invention is a passenger tractor configured to transmit the output from the engine to the front wheels and the front power take-off shaft through separate transmission shafts to drive them. Regarding the transmission structure.
冒記した乗用トラクタの伝動部構造としては、
例えば、実開昭50−8619号公報に記載されている
ように、機体前部に設けたエンジンからの出力を
機体後部のギアトランスミツシヨンで変速し、こ
の変速後の出力を前車輪と後車輪とに各別に伝達
し、走行系ほど多段の変速を必要としない前部動
力取出軸はエンジンから前方に突出させ、この前
部動力取出軸から伝達される出力を別途変速する
ように構成したものが従来から知られている。 The transmission structure of the above-mentioned passenger tractor is as follows:
For example, as described in Japanese Utility Model Application Publication No. 50-8619, the output from the engine installed at the front of the aircraft is shifted by a gear transmission at the rear of the aircraft, and the output after this shift is transferred to the front wheels and rear wheels. The front power take-off shaft, which transmits power to each wheel separately and does not require multiple speed changes as in a driving system, protrudes forward from the engine, and the output transmitted from this front power take-off shaft is configured to be shifted separately. something has been known for a long time.

造が複雑になることの欠点のほかに、ギアトラン
スミツシヨンから前車輪への伝動系に草やワラ屑
等が巻きつき易く、トラブル発生の原因となる欠
点があつた。 In such a conventional power transmission structure, the output shaft from the engine was separately projected forward, and this was used as the front power take-off shaft, so a separate transmission was installed in front of the engine for the front power take-off shaft. In addition to the drawbacks of having to provide a transmission system and the complexity of the operation structure for this transmission, grass and debris can easily get caught in the transmission system from the gear transmission to the front wheels, which can lead to trouble. There was a flaw that caused it.

るとともに、これに対する操作系をも簡略化する
ことが考えられるが、このような構造によれば、
草やワラ屑等の巻きつきが、前車輪への伝動軸だ
けでなく、前部動力取出軸に対する伝動軸につい
ても発生し易くなり、一長一短がある。 Therefore, instead of changing the speed of the front power take-off shaft via a separate transmission device, we changed the speed by partially utilizing the transmission structure for the traveling system in the transmission case installed at the rear of the aircraft. The transmission case is constructed so that the transmission shaft for the front wheels and the transmission shaft for the front power take-off shaft are installed separately toward the front of the aircraft, eliminating the need for a separate transmission for the front power take-off shaft. At the same time, it is possible to simplify the operation system for this, but according to this structure,
Grass, straw, etc. tend to become entangled not only on the transmission shaft for the front wheels, but also on the transmission shaft for the front power take-off shaft, which has its advantages and disadvantages.
本考案は上記実状に鑑みて為されたもので、機

巻き付きを極力回避できるようにすることを目的
とする。 The present invention was developed in view of the above-mentioned circumstances, and involves installing the transmission shaft for the front wheels and the transmission shaft for the front power take-off shaft separately toward the front of the aircraft from the gear transmission case at the rear of the aircraft. However, the purpose is to make the transmission case more compact and to avoid getting grass, straw, etc. around the transmission structure as much as possible.

前記２重軸のうちで、外側筒軸を前記前部動力取

る点にあり、かかる構成から次の作用効果を奏す
る。 To achieve the above object, the transmission structure of the passenger tractor according to the present invention has two transmission shafts mounted between a transmission case at the rear of the machine and a transmission case at the front of the machine. The front wheels and the front power take-off shaft are each driven separately from the front case via the two transmission shafts, and
The two transmission shafts are composed of double inner and outer shafts,
Of the double shafts, the outer cylindrical shaft is used for the front power take-off shaft, and the inner shaft is used for the front wheels, and this configuration provides the following effects.
即ち、両伝動軸の配設スペースを小さくできて

等の除去による中断の少ない状態で能率良く行え
るようになつた。 In other words, the installation space for both transmission shafts can be reduced and the transmission case can be made more compact.As a result, the layout design of the transmission case can be easily designed, and furthermore, the rotating shaft exposed to the outside can be Since there is only one shaft, it is easier to avoid grass and straw debris from getting wrapped around the transmission system to the front wheels and power take-off shaft, and there are fewer interruptions due to removal of grass, etc. wrapped around the transmission shaft for traveling and working equipment. I am now able to work more efficiently under these conditions.

ジヨイント部に泥土が付着しないから、潤滑性が
良好に保つてる利点がある。 Moreover, since the inner shaft is used for power transmission to the front wheels, the transmission shaft to the front wheels with a large transmission torque can be constructed from a solid inner shaft, while the large diameter outer shaft is used for front power extraction. Since it is used for transmission to the shaft, the transmission shaft for the front power take-off shaft, which has relatively few driving opportunities, can be used as a cover for the transmission shaft to the front wheels. It is possible to reduce the amount of grass, etc. that gets wrapped around the wheels, and since mud does not adhere to the joint of the transmission shaft to the front wheels, which has a large transmission torque, it has the advantage of maintaining good lubricity.
