摘要:
A controller of a work vehicle sets the upper limit of a fan target rotational speed in accordance with an engine rotational speed. The controller reduces an upper limit of the fan target rotational speed further when a lock-up clutch is in an engaged state than when the lock-up clutch is in a released state.

A ground leveling control system for a bulldozer, comprising: (a) a cutting edge position detector for detecting a position of a cutting edge of a blade with respect to the ground; and (b) a blade controller for controlling the blade to be lifted or lowered such that the cutting edge position of the blade detected by the cutting edge position detector is kept coincident with a preset target cutting edge position.

An engine unit includes an engine, an exhaust gas treatment device and a connecting pipe. The engine has an exhaust gas port. The exhaust gas treatment device is arranged above the engine. The connecting pipe connects the exhaust gas port and the exhaust gas treatment device. The connecting pipe has an expandable-contractible bellows portion. The bellows portion has a linear form following the upward-downward direction. The lower end portion of the bellows portion is positioned lower than at least a part of the exhaust gas port.

In a work vehicle, an engine compartment is disposed forwards of a cab. An exhaust gas treatment device is disposed over an engine in the engine compartment. A radiator is disposed forwards of the exhaust gas treatment device (33) in the engine compartment. A blower is configured to generate an airflow passing through the radiator from back to front of the radiator. The exhaust gas treatment device is slanted with respect to a vehicle width direction for increasing a distance between the exhaust gas treatment device and the radiator towards a first lateral face portion. Further, the first lateral face portion includes air inlets facing a space between the exhaust gas treatment device and the radiator.

A running slip control system for a bulldozer, comprising: (a) a running slip detector for detecting the running slip of a vehicle body; and (b) a blade controller for lifting a blade to eliminate the running slip when the running slip detector detects the occurrence of running slip.
摘要:
A dozing system for a bulldozer with which dozing can be carried out by a simple operation without giving a great deal of fatigue to the operator.When the running slip of a vehicle body is not detected by a running slip detector, a blade is lifted or lowered by a comparison controller such that an actual tractive force of the vehicle body detected by an actual tractive force detector becomes coincident with a target tractive force set by e.g., a dial, whereby the amount of loads applied to the blade by excavating and moving earth can be maintained constant. On the other hand, when the running slip of the vehicle body is detected by the running slip detector, the comparison controller lifts the blade, thereby reducing the amount of loads applied to the blade by excavating and moving earth in order to eliminate the running slip.

A bulldozer includes a cab and an engine hood. The cab has a foremost surface, and left and right front surfaces. The engine hood has an upper surface, left and right side surfaces, and flat first, second and third inclined surfaces. The first and second inclined surfaces contact the rear side of the upper surface and rear sides of the left and right side surfaces, and are inclined more obliquely to the right rear and left rear than the left and right side surfaces, respectively. The first, second and third inclined surfaces are inclined to face downward to the rear. The third inclined surface contacts the first and second inclined surfaces, and the upper surface. A window attached to the foremost surface is arranged in a vertical direction above first and second sides closest to the foremost surface out of sides constituting the first and second inclined surfaces, respectively.

A blade control system for a bulldozer, comprising: (a) a pitch angle detector for detecting a pitch angle of a vehicle body when the vehicle body inclines back and forth; (b) an actual tractive force detector for detecting an actual tractive force of the vehicle body; and (c) a controller for correcting the actual tractive force detected by the actual tractive force detector according to the pitch angle detected by the pitch angle detector and for controlling the blade to be lifted or lowered such that the corrected actual tractive force becomes equal to a target tractive force.
