Embodiment Construction

[0023] Below will combine the preferred embodiment of the present invention figure 1 and figure 2 , clearly and completely describe the technical solutions in the embodiments of the present invention.

[0024] The invention provides a clutch control system, which is used in a mechanical road roller. see figure 1 , the clutch control system of the first preferred embodiment of the present invention includes an accumulator 10, a first two-position two-way solenoid valve 11, a second two-position two-way solenoid valve 12, a one-way valve 13, a damping hole 14, a pedal valve 15. The first sensor 16, the third two-position two-way solenoid valve 17, the clutch control cylinder 18 and the second sensor 19.

[0025] The energy of the accumulator 10 is provided by a gear pump and a pressure regulating valve installed on the engine to establish a stable pressure and provide hydraulic oil to the first two-position two-way solenoid valve 11 .

[0026] The first two-position two-way...

Abstract

The invention provides a clutch control system and a mechanical road roller with the same. The clutch control system comprises an energy accumulator, a first automatic control switch valve connected with the energy accumulator, a flow control valve connected with the first automatic control switch valve, a clutch control oil cylinder connected with the flow control valve and a second automatic control switch valve connected with the first automatic control switch valve and the flow control valve; when the first automatic control switch valve is electrified, hydraulic oil flows into the clutch control oil cylinder through the energy accumulator, the first automatic control switch valve and the flow control valve; and when the second automatic control switch valve is electrified, the hydraulic oil flows back from the clutch control oil cylinder through the flow control valve and the second automatic control switch valve. The flow control valve plays a role in limiting flow and can ensure that the mechanical road roller to slowly start in an accelerating way, thereby reducing the labor intensity of drivers.

Description

technical field [0001] The invention relates to a clutch control system and a mechanical road roller using the clutch control system. Background technique [0002] At present, the clutch needs to be controlled when the mechanical road roller is walking. Generally, it is operated by hydraulic control and pneumatic power assist. to the transmission mounted 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. The cylinder is connected to the air storage tank installed on the mechanical roller. The air pressure in the cylinder increases with the stroke of the oil cylinder. The clutch is separated under the joint action of air pressure. However, this control method mainly has the following problems: [0003] 1. The mechanical road roller needs to go back and forth to roll the road surface in a short distance, and the clutch pedal is frequently operated. Especial...
