    • PURPOSE: A work vehicle is provided to make a good use of a case block of a hydraulic continuously variable transmission in connecting a front vehicle body and a rear vehicle body, to facilitate a building work including the connection between the front and rear vehicle bodies with a certain level of strength and accuracy, and to prevent deteriorating of a hydraulic oil by improving the cooling of the lubricant. CONSTITUTION: A work vehicle has a large cube unit(12) on a case block(10) of a hydraulic continuously variable transmission used as a construction material of a vehicle connecting the front vehicle body and the rear vehicle body. The large cube unit forms a storage space(S1) for a main clutch(9) on the large cube unit. The work vehicle is equipped with a walling unit for supporting shafts(13) which supports a transmission shafts on the side of the main clutch and a rotating shaft on the side of pump inside the case block. The work vehicle forms a space for mounting gear(S2) inside the walling unit for supporting shafts, and interconnects the space for mounting gear with a transmission chamber space(S4) where exists a pump(P) and a motor of the hydraulic continuously variable transmission device at a transmission block unit(11) to be able to circulate hydraulic oil.
    • 目的:提供一种工作车辆,用于充分利用连接前车身和后车身的液压无级变速器的箱体块,以便于包括前后车体之间的连接的建筑工作, 一定程度的强度和精度,并且通过改善润滑剂的冷却来防止液压油的劣化。 构成:工作车辆在用作连接前车体和后车身的车辆的构造材料的液压无级变速器的箱体(10)上具有大立方体单元(12)。 大立方体单元形成大立方体单元上的主离合器(9)的存储空间(S1)。 工作车辆配备有用于支撑轴(13)的壁部单元,该轴支撑主离合器侧的传动轴和壳体内的泵侧的旋转轴。 工作车辆在用于支撑轴的壁化单元内部形成用于安装齿轮(S2)的空间,并且将用于安装齿轮的空间与存在泵(P)的传动室空间(S4)和液压连续变量的电动机 传动装置在传动块单元(11)上能够循环液压油。

    • A frameless type working vehicle includes an intermediate vehicle body 5 acting as a body forming member for interconnecting a front vehicle body 3 and a rear vehicle body 4. The intermediate vehicle body is formed of a case block 10 housing a hydrostatic stepless transmission (HST) 20. The case block 10 includes, formed integral with one another, a small diameter portion 11 connected to the rear vehicle body 4 and providing case walls for a pump P and a motor M of HST 20, a large diameter portion 12 connected to the front vehicle body 3 and having an upper edge at a higher level than an upper surface of the small diameter portion 11, and a transitional portion 12A disposed between the small diameter portion 11 and the large diameter portion 12. The large diameter portion 12 defines an accommodating space S1 for a main clutch 9 that receives drive from an engine E.
    • 无框式作业车辆具备作为使前部车身3与后部车身4连结的车身形成构件的中间车身5.中间车身由收容静液压式无级变速器(HST)的箱体10, 箱体10包括彼此一体形成的小直径部分11,小直径部分11连接到后部车体4并且提供用于HST 20的泵P和马达M的箱壁,大直径部分12连接到 并且具有比小直径部分11的上表面高的水平高度的上边缘以及设置在小直径部分11和大直径部分12之间的过渡部分12A。大直径部分12限定 用于接收来自发动机E的驱动的主离合器9的容纳空间S1。
