Pressure cut-off valve: When the high-pressure relief valve continues to move, the pressure cut-off valve will make the displacement servo cylinder in the direction of small displacement back swing, high pressure relief valve to avoid prolonged overflow caused by oil temperature, the pressure cut valve The set pressure is 380 bar. Charge-Relief Valve: Maintains the charge pressure of the system and sets the charge relief valve to 24 bar.
Flushing valve: the main oil in the low-pressure side of the hydraulic oil flush out part of the tank, and one-way valve with the maintenance of the main
Oil hydraulic oil exchange.
When the roller is working, it can control the angle of the pump swashplate by changing the angle of the manual servo handle of the pump and change the output flow and direction of the pump to change the running speed and direction of the roller. The variable plunger motor controls the skew by adding the control valve Shaft swing angle, so that the motor displacement between the minimum displacement and maximum displacement, the roller has two levels of stepless adjustable speed to meet the driving, compaction and other conditions of the different requirements.
Drive motor mounted on the planetary reducer, planetary reducer in the normally closed wet multi-disc brakes, pressure Road
Machine work through the hydraulic oil to release, before and after the wheel of the normally closed wet multi-disc brake to ensure that the roller has a reliable braking, improved safety performance of the road roller.

The traveling hydraulic system of the tire roller adopts the swash plate type axial piston pump and two inclined axis type axial piston motors in parallel
(High-pressure relief valve, one-way charge valve), pressure cut-off valve, charge-relief valve and pressure relief valve to ensure the normal operation of the closed-loop circuit, and the closed circuit (see schematic diagram) Flushing valve, now the main function of the various valves and single drum roller drive system similar to this is not repeated.
