Abstract

The invention provides a full-hydraulic clutch control system and a road roller comprising the system. The full-hydraulic clutch control system comprises a hydraulic pump (20), a liquid filling valve bank (30), a clutch control mechanism and an energy accumulator (40); the hydraulic pump (20) is connected to an oil source (10) and outputs pressure oil; the liquid filling valve bank (30) is arranged on the downstream of the hydraulic pump (20) and comprises at least one relief valve; the clutch control mechanism is arranged on the downstream of the liquid filling valve bank (30) and used for controlling a state of a clutch (70); and the energy accumulator (40) is connected to a hydraulic pipeline between the liquid filling valve bank (30) and the clutch control mechanism. Through the full-hydraulic clutch control system, power needed to control the clutch can be quickly and stably provided for the clutch control mechanism, fast and effective operation on the clutch is realized, and higher reliability and stability are achieved. The road roller comprises the full-hydraulic clutch control system.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to a full hydraulic clutch control system and a road roller containing the system. Background technique [0002] At present, the clutch control system of road rollers is mainly controlled by hydraulic control and pneumatic power assist. Clutch booster, the clutch booster is composed of oil cylinder and air cylinder. The oil cylinder is connected to the small oil cylinder in the cab through the oil pipe, and the cylinder is connected to the air storage tank installed on the road roller. Under the same effect of air pressure and air pressure, the clutch is separated. This control method mainly has the following problems: [0003] 1. Two sets of hydraulic and pneumatic systems are required for clutch control, which is expensive; [0004] 2. The number of parts is large and the pipeline connection is complicated; [0005] 3. The reliability is poor, either the hydraulic system or the pneumatic s...
