Problems solved by technology
[0002] When the existing wet hydraulic clutch is combined, the combination of the overflow valve and the reversing valve will cause an impact when the clutch is combined, causing the transmission system to vibrate; using the combination of the secondary pressure control valve and the reversing valve, the clutch will work The pressure ramp-up time has a great influence with the change of ambient temperature. When working with heavy load, the clutch will be seriously worn and aged

The invention relates to a pressure control valve, in particular to a three-level pressure control valve for controlling a wet clutch, and a control method thereof. The three-level pressure control valve is applicable to controlling one or multiple wet clutch sets and comprises a valve body. The upper portion of the valve body is provided with an electromagnetic reversing valve. The electromagnetic reversing valve controls a pressure relief device and a wet clutch. An oil pump pressure oil incoming passage is arranged in the valve body and the oil pump pressure oil incoming passage is communicated with the electromagnetic reversing valve through a pressure oil incoming reversing valve passage. The electromagnetic reversing valve is communicated with both an electromagnetic reversing valve oil circuit passage and an electromagnetic reversing valve entry clutch passage. The three-level pressure control valve for controlling a wet clutch and the control method thereof have the advantages that the structure is compact, reliability is high, the service life of equipment is prolonged, and application efficiency is improved.
Description
technical field [0001] The invention relates to a pressure control valve, in particular to a three-stage pressure control valve for controlling wet clutches and a control method thereof, which can control one or more sets of wet clutches. Background technique [0002] When the existing wet hydraulic clutch is combined, the combination of the overflow valve and the reversing valve will cause an impact when the clutch is combined, causing the transmission system to vibrate; using the combination of the secondary pressure control valve and the reversing valve, the clutch will work The pressure ramp-up time has a great influence with the change of ambient temperature. When working with heavy load, the clutch will be seriously worn and aged. Contents of the invention [0003] The present invention mainly solves the deficiencies in the prior art. It has a compact structure and provides three different working oil pressures. Each working oil pressure realizes different working st...
