| Abstract: | The principle and structure of the hydro-viscous drive (HVD) set was introduced. Through theoretical analysis of the characteristic of the electro-hydraulic control system in a HVD, the conclusions were obtained that the non-linearity of the pressure performance curve and dynamic pressure instability of the pilot-operated electro-hydraulic pressure relief valve, which was used for HVD speed regulating purpose and usually worked within micro flow-rate and low oil pressure state, were the main causes of the poor open-looped performance. So a special speed regulating valve for HVD set was developed, with which the performance of open-looped rotation of HVD set was much improved. The principle of the special speed regulating valve for HVD set was elaborated in this paper, and the special points which should be noticed during design was also depicted. |
