    摘要： [PROBLEM] To provide a steering system for a construction vehicle, which is suited not only for traveling on general roadways but also for work at construction sites and can performhigh-reliability steering control. [SOLUTION] A steering system for a construction vehicle is provided with a directional control valve 5 for controlling a flow of pressure oil to body-articulating hydraulic cylinders 2 that perform steering and also with a steering-wheel-operated signal generation means 6 for outputting by operation of a steering wheel 7a a pilot signal to the directional control valve 5 for switching the valve 5. The steering system is also provided with a lever-operated signal generation means for producing by operation of a lever 10a a pilot signal to switch the directional control valve 5, said lever-operated signal generation means including pressure-proportional solenoid valves 12a,12b or the like, selector valves 13a,13b switchable to permit selectively outputting the pilot signal fromone of the signal generation means to the directional control valve 5, and an automated switching means for switching the selector valves 13a, 13b such that upon operation of the steering wheel 7a, the pilot signal from the steering-wheel-operated signal generation means 6 can be preferentially outputted to the directional control valve 5.

    摘要： A motor-assisted joint system is provided to improve maneuverability and safety of an articulated bus. The motor-assisted joint system is enabled when the articulated bus is operated in an active damping mode. An articulated joint with a flat motor is used. According to the velocity of the articulated bus, a highly sensitive damping force is calculated and an opposing force is generated to balance the inertia of the articulated bus when an oversteering event or a tire slip event occurs. Consequently, the driving performance of the articulated bus in various aspects is enhanced.

    摘要： When engaged, an articulation controller automatically adjusts an angle of articulation between a front frame and a rear frame of a motor grader based on a steering angle of the front wheels. If a groundspeed of the motor grader exceeds a threshold groundspeed, the articulation controller enters a mode that only allows decreasing the angle of articulation of the motor grader. When the angle of articulation reaches zero, the articulation controller disengages until the groundspeed is reduced below the threshold groundspeed.

    摘要： The invention relates to a method for controlling a working machine (1). The working machine comprises a front section (2) having a frame (7) and a pair of wheels (8a, 8b) arranged on a geometrical front wheel axis (16), and a rear section (4) having a frame (9) and a pair of wheels (10a, 10b) arranged on a first geometrical rear wheel axis (18) and a pair of wheels (11a, 11b) arranged on a second geometrical rear wheel axis (19) arranged behind the first rear wheel axis (18). The front section (2) and the rear section (4) are pivotally connected to each other for pivoting about a substantially vertical pivot axis (13). The distance (15) from the geometrical front wheel axis (16) to the vertical pivot axis (13) being shorter than the distance (20) from the vertical pivot axis (13) to the second geometrical rear wheel axis (19). The method comprises the steps of determining an operation parameter value indicative of the traction between a driven wheel of the rear section and the ground, and based on the determined parameter value selecting between a first control mode and a second control mode, and in the first control mode steering the wheels (11a, 11b) of the second geometrical rear wheel axis (19) to substantially follow the same tracks as the wheels (8a, 8b) of the geometrical front wheel axis (16) when driving the working machine (1) during cornering, and in the second control mode steering the wheels (11a, 11 b) of the second geometrical rear wheel axis (19) to follow tracks which are different from the tracks of the wheels (8a, 8b) of the geometrical front wheel axis (16) when driving the working machine during cornering.
