摘要： It is possible to prevent generation of failure in a dump truck and diagnose a true cause of failure in a short period of time. Thus the present failure diagnosis method diagnoses an operation and function of at least one of respective devices such as an engine at a predetermined engine rotation speed, transmission, respective axles, respective suspensions, hydro-pneumatic systems and a brake while a body (4) descends after evacuation of loading. The failure diagnosis device comprises body operating means (50) for raising or lowering a body, a direction switching valve (7) for receiving a command from the body operating means to lower the body, and a self-diagnosis control device (11) for using state detecting means (20) to detect and store a state of at least one of the respective devices at a predetermined engine rotation speed when the body operating means is at a predetermined operative position and for comparing a magnitude of a detected value and a rate of change with reference values on the basis of hysteresis data when carrying out failure diagnosis.

摘要： A fully hydraulic steering system is provided with a steering valve, which sends out discharge pressure oil from a hydraulic pump in proportion to a control input of a handle, and a directional control valve, by which discharged pressure oil from the steering valve is changed over as pilot pressure and discharged pressure oil from the hydraulic pump is fed to a steering cylinder. Said directional control valve is so designed that a spool inserted into a spool hole of the valve body can be freely displaced from its neutral position to a first position, in which discharged pressure oil from the hydraulic pump is fed to one of oil chambers in the steering cylinder and pressure oil in the other oil chamber is allowed to flow into a tank, and to a second position, in which discharged pressure oil from the hydraulic pump is fed to the other oil chamber in the steering cylinder and pressure oil in the one of the chambers is allowed to flow into the tank. In this fully hydraulic steering system, a small diameter portion and a cut groove for the inflow of pressure oil from the steering cylinder into the tank are formed on the spool. Furthermore, the cut groove is so shaped that, when the spool is displaced from the neutral position toward the first position or the second position, the opening area thereof is increased until the spool is displaced to an intermediate position and is then decreased thereafter.

摘要： A hydraulic driving device for the steering wheel of a dump truck in which a hydraulic motor can be mounted and/or dismounted therefrom after it has been assembled to thereby make the size of the hydraulic motor larger. A driving shaft (20) is rotatably supported on a supporting shaft portion (7) of a receiving seat (6) supported by a yoke (5), and a steering wheel (2) is rotatably mounted on the outer circumference of this supporting shaft portion (7). The steering wheel (2) and one end of the driving shaft (20) are coupled together via a speed reduction mechanism (27), and the motor main body (33) of a hydraulic motor (32) is mounted by means of a bolt (34) on the supporting shaft portion (7) in a position opposite to the steering wheel (2). The rotating shaft (35) of the motor is caused to protrude inside the supporting shaft portion (7) so as to be coupled to the other end of the driving shaft (20), whereby it is possible to mount or dismount the motor (32) by tightening or loosening the bolt (34).
