この発明の実施例を図面に基づき説明する。   An embodiment of the present invention will be described with reference to the drawings.

図１は、トラクタの側面図を示すものであり、この走行車体１前部のボンネット２内部にエンジンＥを搭載し、このエンジンＥの回転動力をミッションケース３内の変速装置に伝え、この変速装置で減速された回転動力を前輪４及び後輪５に伝えるようにしている。後輪５はフェンダ５ａで覆われており、後輪５で跳ね飛ばされた泥などが運転席７に飛散しない構成としている。   FIG. 1 shows a side view of a tractor. An engine E is mounted inside a bonnet 2 at the front of the traveling vehicle body 1, and the rotational power of the engine E is transmitted to a transmission in a transmission case 3. The rotational power decelerated by the device is transmitted to the front wheels 4 and the rear wheels 5. The rear wheel 5 is covered with a fender 5 a so that mud or the like splashed by the rear wheel 5 does not scatter to the driver seat 7.

エンジンＥの後方に前輪４，４を操舵するステアリングハンドル６が装備され、更に、その後方には運転席７が設置されている。また、運転席７の後方には安全フレーム７ａが設置されている。   A steering handle 6 for steering the front wheels 4 and 4 is provided behind the engine E, and a driver's seat 7 is installed behind the steering handle 6. A safety frame 7 a is installed behind the driver seat 7.

エンジンＥの左右両側を支持し、走行車体１の前部まで延びる機体フレーム８を備えている。この機体フレーム８は、左右に略平行な左右プレート９Ｌ,９Ｒと前側を横方向に繋いで設ける前部フレーム９Ｆとからなり、平面視で略コの字型に形成されている。   A body frame 8 that supports the left and right sides of the engine E and extends to the front of the traveling vehicle body 1 is provided. The body frame 8 includes left and right plates 9L and 9R that are substantially parallel to the left and right and a front frame 9F that connects the front side in the lateral direction, and is formed in a substantially U shape in plan view.

エンジンＥの動力をクランクプーリ部から前方に向けて伝動する伝動軸１１は、その前後に自在継手１１ａを設けており、中間部で２分割して角スプライン嵌合として長手方向に伸縮自在に構成してある。   The transmission shaft 11 that transmits the power of the engine E forward from the crank pulley portion is provided with a universal joint 11a at the front and rear thereof, and is configured to be divided into two at the middle portion so that it can expand and contract in the longitudinal direction as an angular spline fitting. It is.

これにより、伝動軸１１の径を小さくできる。そして、機体に負荷が生じても、伝動軸１１は長手方向に伸縮するので、伝動軸１１の損傷を防止できる。   Thereby, the diameter of the transmission shaft 11 can be made small. Even if a load is generated on the airframe, the transmission shaft 11 expands and contracts in the longitudinal direction, so that the transmission shaft 11 can be prevented from being damaged.

また、伝動軸１１の周囲はカバーで覆う構成としているので、伝動軸１１の角スプライン部に泥などが付着するのを防止できる。   Further, since the periphery of the transmission shaft 11 is covered with a cover, mud and the like can be prevented from adhering to the angular spline portion of the transmission shaft 11.

そして、その伝動軸１１に連結して回転数を変速するギヤを内装するギヤケース１２を機体の前部に構成している。伝動軸１１の回転動力はギヤケース１２に入力して変速され、その前面から走行車体前側に突出するフロントＰＴＯ軸１３を駆動する構成としている。   A gear case 12 that is connected to the transmission shaft 11 and houses a gear that changes the rotation speed is formed at the front of the airframe. The rotational power of the transmission shaft 11 is input to the gear case 12 to be shifted, and the front PTO shaft 13 protruding from the front surface to the front side of the traveling vehicle body is driven.

また、前記伝動軸１１は、機体フレーム８を構成する左右プレート９Ｌ,９Ｒの間に設けられ、しかも、アクスルケースブラケット１４の切り欠き部１５を通した構成になっている。   The transmission shaft 11 is provided between the left and right plates 9 </ b> L and 9 </ b> R constituting the body frame 8, and is configured to pass through the notch 15 of the axle case bracket 14.

このように、アクスルケースブラケット１４に切り欠き部１５を形成し、この切り欠き部１５に伝動軸１１を通過させる構成としたので、上下方向をコンパクトに構成できる。   Thus, since the notch part 15 is formed in the axle case bracket 14 and the transmission shaft 11 is allowed to pass through the notch part 15, the vertical direction can be made compact.

ギヤケース１２は、機体フレーム８の左右のプレート９Ｌ,９Ｒと横方向に繋ぐ前部のプレート９Ｆとによって囲まれる空間で支持される構成になっており、ボルトで固定されている。また、伝動軸１１の折角度を少なくするために、即ち、伝動軸１１をできるだけ前後方向に対して直線状に配置するために、ギヤケース１２を前部のプレート９Ｆ直後に取り付けると、フロントＰＴＯ軸１３をコンパクトに取り出せ、フロント装着作業機を本機に近接して装着でき、バランスの良い作業が可能となる。   The gear case 12 is configured to be supported in a space surrounded by the left and right plates 9L and 9R of the body frame 8 and the front plate 9F connected in the lateral direction, and is fixed by bolts. If the gear case 12 is attached immediately after the front plate 9F in order to reduce the folding angle of the transmission shaft 11, that is, to arrange the transmission shaft 11 as linearly as possible in the front-rear direction, the front PTO shaft 13 can be taken out in a compact manner, and the front mounting work machine can be mounted close to the main unit, thus enabling a balanced work.

ギヤケース１２の後部をケースステー２０に固定し、ケースステー２０は機体フレーム８を構成する左右のプレート９Ｌ,９Ｒに固定している。   The rear portion of the gear case 12 is fixed to the case stay 20, and the case stay 20 is fixed to the left and right plates 9 </ b> L and 9 </ b> R constituting the body frame 8.

また、ギヤケース１２は、バッテリ１７を載せるバッテリベースプレート１８の下方に設けられ、メンテナンスが容易に行えるようにしている。また、バッテリベースプレート１８は、下面をフラットにし、前記伝動軸１１がその下方ぎりぎりを通るようにしている。ギヤケース１２の下部をアクスルブラケットの１４の下方に突出させ、ケース下部の前面にフロントＰＴＯ軸１３を突設した構成になっている。   Further, the gear case 12 is provided below the battery base plate 18 on which the battery 17 is placed so that maintenance can be easily performed. Further, the battery base plate 18 has a flat bottom surface so that the transmission shaft 11 passes the lower limit. The lower part of the gear case 12 protrudes below the axle bracket 14, and the front PTO shaft 13 is projected from the front surface of the lower part of the case.

また、前記フロントＰＴＯ軸１３は、前部のプレート９Ｆの下方に設けられ、更にその前方に突出した構成になっている。また、フロントＰＴＯ軸１３には、この左右及び上方を覆う保護カバー１６（保護カバー左部１６ａ，保護カバー右部１６ｂ，保護カバー上部１６ｃ）がギヤケース１２の前面に設けられ、フロントＰＴＯ軸１３を安全に保護している。   The front PTO shaft 13 is provided below the front plate 9F and further protrudes forward. Further, the front PTO shaft 13 is provided with a protective cover 16 (protective cover left portion 16a, protective cover right portion 16b, protective cover upper portion 16c) covering the left and right and upper portions on the front surface of the gear case 12, and the front PTO shaft 13 is attached to the front PTO shaft 13. Safely protected.

これにより、フロントＰＴＯ軸１３に接触するのを防止できる。また、フロントＰＴＯ軸１３が風雨にさらされるのを防止できる。   Thereby, contact with the front PTO shaft 13 can be prevented. Further, the front PTO shaft 13 can be prevented from being exposed to wind and rain.

前記前部プレート９Ｆには牽引用のヒッチ１９が取り付けられ、牽引用ヒッチ１９はフロントＰＴＯ軸１３の上方に設けられている。牽引用ヒッチ１９とフロントＰＴＯ軸１３にはフロント作業機が容易に装着される。   A tow hitch 19 is attached to the front plate 9F, and the tow hitch 19 is provided above the front PTO shaft 13. A front working machine is easily mounted on the tow hitch 19 and the front PTO shaft 13.

機体フレーム８の側面には、前後方向の力を受けるため、補強部材２１が設けられている。   A reinforcing member 21 is provided on the side surface of the body frame 8 to receive a force in the front-rear direction.

これにより、ギヤケース１２、伝動軸１１、フロントＰＴＯ軸１３の振動を抑制できる。   Thereby, the vibration of the gear case 12, the transmission shaft 11, and the front PTO shaft 13 can be suppressed.

また、エンジンＥからの排気管２３の排気口２３ａは、左のプレート９Ｌの側方であってボンネット２の下方に配置している。これにより、排気口２３ａ内に雨などが進入するのを防止でき、デザイン性も向上する。   Further, the exhaust port 23a of the exhaust pipe 23 from the engine E is disposed on the side of the left plate 9L and below the bonnet 2. Thereby, it is possible to prevent rain and the like from entering the exhaust port 23a, and the design is improved.

なお、図中、２２は、エンジンを冷却するラジエータを示す。   In the figure, reference numeral 22 denotes a radiator for cooling the engine.
