摘要： One operating lever is provided for moving a traveling vehicle with a working machine back and forth and the working machine vertically and operating a sub-transmission, and a sub-transmission switch (37) is provided in a recessed portion (30b) formed in a grip (30a) of a back-and-forth operating lever (30) so that a quick operation can be effected by a single hand without any mistake. In addition, the working machine vertically moving lever (32) is constructed so as to interlock with a spool of a vertical motion control valve via a motor so that the speed of the motor is gradually reduced when the working machine vertically moving lever (32) is in a lowering operation, whereby a drastic lowering is prevented.

摘要： A drive unit provided with a power transmission path interlockingly connecting an engine (E) to left and right sprockets (12L, 12R), which are adapted to drive left and right crawlers (11) of left and right traveling parts (1L, 1R), via a non-stage traveling transmission (21) and an auxiliary traveling transmission unit (28) capable of changing the speed of a working vehicle in a plurality of stages. The power transmission path is provided with a non-stage steering transmission (20), left and right steering transmission units (48L, 48R) and left and right planetary gears (40L, 40R) all of which are adapted to be operated for speed change in accordance with a turning operation of a steering wheel (7). This construction enables a pivot turn and a spin turn of a working vehicle body to be made, the swinging performance of the working vehicle to be improved, the maneuvering of the vehicle to be done easily, and the construction of the drive unit to be simplified. It also becomes possible for the vehicle body to travel in a speed range which cannot be covered by the non-stage traveling transmission alone, and reduce the fuel consumption by lowering an output rotational frequency of the non-stage traveling transmission during a high-speed travel of the vehicle on a road.
摘要翻译：驱动单元，其具有将发动机（E）与左右行驶部（1L，1R）的左右履带（11）驱动的左右的链轮（12L，12R）互相连接的动力传递路径，通过能够改变多级的作业车辆的速度的非级行驶传动装置（21）和辅助行驶传动装置（28）。动力传递路径设有非转向传动装置（20），左右转向传动装置（48L，48R）和左右行星齿轮（40L，40R）均适用于变速操作根据方向盘（7）的转动操作。这种结构能够实现作业车体的枢转转动和旋转转动，提高作业车辆的摆动性能，容易地进行车辆的操纵，以及简化的驱动单元的构造。车体能够在不能被非级行驶传动装置单独覆盖的速度范围内行驶，并且通过在高速下降低非级行驶传动装置的输出转速来降低燃料消耗车辆在路上行驶。

摘要： A pump operating unit (40) is provided in an operating section for controlling the steering and speed change of travelling sections (1L, 1R) connected interlockingly to a pair of variable flow rate control pumps (PL, PR) via link mechanisms (NL, NR) for a spool, and operated by a steering mechanism (33) and a speed changing mechanism (37). Accordingly, the natural vibration occurring in the variable flow rate control pumps (PL, PR) is absorbed by the link mechanisms (NL, NR), and hence the vibration transmitted to the pump operating unit (40) is attenuated. The propagation of the vibration to the steering mechanism (33) and speed changing mechanism (37), which are interlockingly connected to the pump operating unit (40), is prevented.
摘要翻译：泵操作单元（40）设置在操作部分中，用于控制通过连杆机构（NL，L，L）互连地连接到一对可变流量控制泵（PL，PR）的行驶部分（1L，1R）的转向和速度变化， NR），并由转向机构（33）和变速机构（37）操作。因此，可变流量控制泵（PL，PR）中发生的固有振动被连杆机构（NL，NR）吸收，因此传递到泵运转单元（40）的振动被衰减。防止了与泵操作单元（40）互锁地连接到转向机构（33）和变速机构（37）的振动传播。
