難である。
The body frame of a passenger tractor is generally long in the longitudinal direction, and the propulsion shaft is passed through the center of the frame.
The front, middle, and rear parts of the body frame are equipped with the engine and the front axle outer tube, and the transmission and the rear axle outer tube are attached to the rear. The shape structure is different. Therefore, it is difficult to construct the vehicle body frame integrally from the beginning.
そこで従来は、前部フレームと中央フレームと
後部フレームを別体に作り、それら3部材相互を
フランジ継手を介してボルト締めによつて結合し
ている。 Therefore, conventionally, the front frame, the center frame, and the rear frame are made separately, and these three members are connected to each other by bolting through a flange joint.
ところが、前後方向に長いけた状フレームがそ
の途中の数ケ所でフランジ結合されていると、そ
のフランジの合せ部分がフレーム強度の最も弱い
所となり、フレーム全体の強度のバランスを無く
している。
However, when a longitudinally long beam-like frame is joined by flanges at several points along the way, the flanges meet at the weakest point of the frame, causing an imbalance in the overall strength of the frame.
またフランジの溶接・ボルト穴の加工・ボルト
締めなどを必要とするので、工数が多く、寸法精
度も出しにくい。 In addition, it requires welding flanges, drilling bolt holes, tightening bolts, etc., which requires a lot of man-hours and makes it difficult to achieve dimensional accuracy.
さらに車軸に差動歯車装置を設ける機種の場

レームの下に取付けているため車高が高い。従つ
て不整地走行に適さない。 Furthermore, in the case of a model in which a differential gear device is provided on the axle, the vehicle height is high because the case containing the differential gear device is attached under the vehicle body frame. Therefore, it is not suitable for driving on rough terrain.
本発明は、乗用トラクタのけた状車体フレーム
