    • PURPOSE:To prevent mutual interference of front/rear chassis by integrally providing two stoppers for limiting articulation and oscillation to a member for coupling the front/rear chassis rotatably in horizontal direction while rollably around the axis in backward/forward direction. CONSTITUTION:A working car such as an articulate steering shovel loader has front and rear chassis 2, 3 to be coupled through coupling mechanism 4. The coupling mechanism 4 is constructed by fixing a coupling member extending in backward/forward direction or an oscillate pin 17 rotatably in horizontal direction to an articulate pin 16 journaled between upper and lower plates 15, 15 of front chassis frame 14. Here, the oscillate pin 17 is formed with a stopper (projection) 21 contactable against a stopper 25 at the front chassis 2 side to control the articulate and second stopper 23 contactable against a stopper 28 provided at the rear chassis 3 side to control oscillate.
    • 目的:为了防止前/后机架的相互干扰,通过一体地提供两个限位器,用于将铰接和摆动限制在一个构件上,用于将前/后机架在水平方向上可旋转地连接,同时在向后/向前方向上可滚动地围绕轴。 构成:诸如铰接式转向铲装载机的工作车辆具有通过联接机构4联接的前后底盘2,3。联接机构4通过固定沿向后/向前方向延伸的联接构件或振荡销17 可旋转地沿着前框架14的上板15和下板15之间的关节销16旋转。这里,摆动销17形成有止动件(突起)21,该止动件可与前机架2侧的止动件25接触 以控制与设置在后机架3一侧的止动件28可接触以控制摆动的铰接和止动件23。

    • PURPOSE:To enable the quick turnig and the easy assembly in a vehicle connecting front and rear car bodies to be rotatable by connecting a motor part and drive wheels selectively provided on both car bodies without influencing the turning angle of car bodies. CONSTITUTION:A front car body 7 and a rear car body 11 are connected to be rotatable around a vertical axis P. The front car body 7 with a drive part 3 and the rear car body 11 with drive wheels 10 are respectively provided. At this stage, several oil pressure pumps P1-P4 are connected to the drive part 3 and oil pressure motors M1 and M2 are connected to input shafts of differential systems 13 and 14 of front and rear wheels 6 and 10. Oil pressure pumps P1 and P2 are connected to oil pressure motors M1 and M2 through pipes 15 and 16 respectively, while oil pumps P3 and P4 are connected to pipes 9 and 12 for dumping and steering respectively through pipes 17 and 18. This construction permits to drive the oil motors M1 and M2 by the supply and the discharge of pressurized oil from oil pressure pumps P1 and P2 driven by the drive part 3.
    • 目的:为了使连接前后车体的车辆能够快速地开启并容易组装,可以通过连接一个电动机部件和选择性地设置在两个车体上的驱动轮,而不会影响车身的转动角度。 构造:前车体7和后车体11连接成能够绕垂直轴线P旋转。分别设置有具有驱动部3的前车体7和具有驱动轮10的后车体11。 在这个阶段,几个油压泵P1-P4连接到驱动部分3,油压马达M1和M2连接到前后轮6和10的差速系统13和14的输入轴上。油压泵P1和 P2分别通过管道15和16连接到油压马达M1和M2,而油泵P3和P4分别通过管道17和18连接到用于倾卸和转向的管道9和12。这种结构允许驱动油马达M1 通过从由驱动部3驱动的油压泵P1和P2供给和排出加压油来实现。

    • PURPOSE:To make stable turning steerage performable, by letting a turning proper expansion body contract according to a detection value of a turning angle commensurate to a wheeling angle in time of the turning steerage to the mountain side at a slope way, while turning a dumper rear body with the center- of-gravity movement around a turning shaft. CONSTITUTION:During drive of a transport vehicle, wheel rectilinearky driving on a slope way while sighting, for example, the mountain sie to the right, if a teering wheel 20 turns round clockwise, turning to the right as far as an A angle, this turning angle is detected by a turning angle detecting sensor 35. If so, a group of solenoid valves inside a hydraulic circuit are controlled for their opening or closing by a controller, whereby a turning proper expansion body of a hydraulic cylinder or the like is set in motion for contraction, and a dumper rear body 9 installed on a turning table 7 is turned round as far as a B angle clockwise around a turning shaft 5. In consequence, a cneter-of-gravity position shifts from G1 to G2 so that the transport vehicle somes possible to rotate in a stable mannr.
    • 目的:为了进行稳定的转向操纵,通过使转弯适当的膨胀体根据与倾斜方向转向山侧的转向角相当的转角的检测值来收合,同时转动自卸车 后身体围绕转轴进行重心运动。 规定:在运输车辆的行驶过程中,车轮直线行驶在斜坡上,例如右侧的山,,如果一个调光轮20顺时针旋转,向右转一个A角,这个 旋转角检测传感器35检测转向角度。如果是这样,则通过控制器控制液压回路内的一组电磁阀,以使其开启或关闭,由此设置液压缸等的转动适当的膨胀体 在收缩时运动,并且安装在转台7上的翻斗车后体9围绕转动轴5顺时针旋转至B角。因此,重心位置从G1向G2转动,使得 运输车辆有可能在稳定的甘露中旋转。
