Volvo A25E 4×4 Articulated Dump Truck Shop Manual

Hydraulic system, description

The hydraulic system consists of five hydraulic pumps of piston type with endless variable displacement. Two pumps are for the steering and dumping system, two are for driving the fans and there is one ground-dependent hydraulic pump on the dropbox. The ground-dependent pump delivers oil via a non-return valve to the hydraulic system when the machine is in moving.

• The dumping system is connected in parallel and series with the steering system, and have common hydraulic pumps. However, the steering system has priority over the dumping system to safeguard the steering function at all times. When only dumping, all working pumps provide flow to the dumping system, When steering, a hydraulic pump is connected directly to the steering system, and thus, it is possible to steer and dump at the same time.
• Control of the fans’ speed (rpm) takes place with two PWM–valves located on the fan pumps, which receive signals from the vehicle electronics. The electronics sense the temperature in the different cooling systems and control the rpm between basic fan rpm and max. fan rpm. This is controlled electrically. In case of missing signal from the electronics, the fans are controlled.
• The dumping system is servo-operated and is controlled with hydraulic oil from the dumping valve. The dump lever has four positions: lower with pressure, lower/float, hold and dump. The lever has fixed positions in lower/float or hold. When the current is cut off or the operator leaves the operator’s seat, the lever automatically goes to the hold position. The lever can be locked in the hold position with a lock device.
