摘要： An axle driving apparatus which is so constructed that an input pulley for engine power is set lower in mounting position with respect to the axis of a driving axle so s to enable the platform of a vehicle to be lowered. The engine position lowers to promote miniaturization, a lower center of gravity and running stability of the vehicle. For maintenance of the transmission for driving the axle, the entire axle driving apparatus need not be removed from the frame of the vehicle. A bearing for supporting the axle to the casing is held with exact dimensional precision so as not to cause a backlash on the axle, to thereby prolong the life span of the bearing. The axle is ensured to be sealed, the number of mounting bolts for the casing need not be increased in order to improve rigidity, and the casing is strong so that the assembly time for the axle driving apparatus is minimized.
摘要翻译：一种车轴驱动装置，其构造成使得用于发动机动力的输入滑轮相对于驱动轴的轴线的安装位置设定得较低，以使车辆的平台能够降低。发动机位置降低以促进小型化，较低的重心和车辆的运行稳定性。为了维护用于驱动车轴的变速器，整个车轴驱动装置不需要从车辆的车架上移除。用于将轴支撑到壳体的轴承具有精确的尺寸精度，以便不会在轴上产生齿隙，从而延长轴承的使用寿命。确保轴被密封，为了提高刚性，不需要增加用于壳体的安装螺栓的数量，并且壳体坚固，使得轴驱动装置的组装时间最小化。

摘要： A first hydraulic pump P1 driven by power of an engine and a first hydraulic motor M1 are fluidly connected so as to form a closed fluid circuit. An output shaft 2 of first hydraulic motor M1 is drivingly connected with a sub-transmission 3. The output power from sub-transmission 3 drives main-driving wheels 5 and also drives a second hydraulic pump P2 fluidly connected with a second hydraulic motor M2 for driving sub-driving wheels 6. A clutch 7 is interposed between an output shaft 4 of sub-transmission 3 and an input shaft 9 of second hydraulic pump P2 or on the output side of second hydraulic motor M2. Second hydraulic pump P2 or second hydraulic motor M2 has variable displacement, so that second hydraulic motor M2 is drivingly accelerated in proportion to the degree of turning operation of a steering operating tool 31. In case that a plurality of front reel mowers 8FL, 8FM and 8FR are disposed in front of the vehicle body, a pair of decelerator casings 29 are disposed on both lateral sides of transmission casing 1 for driving main-driving wheels 5. Decelerator casings 29 project horizontally forward and support main-driving wheels 5 respectively at their front portions. Middle front reel mower 8FM is disposed between left and right decelerator casings 29.

摘要： A variable displacement type hydraulic system is contained in a housing. A guide is provided on an axis of slanting movement of a swash plate. The guide is fitted into an inner ring of a roller bearing. The roller bearing is fitted into a groove formed at an inner wall of the housing and a groove formed at a cylinder block mounting surface of a center section so as to be fixedly positioned in the housing. In accordance with the invention, sliding resistance of the swash plate is reduced to improve the ability of the swash plate to return to the neutral position.
