| Abstract: | The JCMFVD30T hydraulic control system is a kind of new technology which is based on the introduction from TCM Co.,Japan and the improvement of the existing technologies.Via the inching valve and the cuisine valve,the vehicular shifting is carried out.Meanwhile,the automatic transmission of vehicles is also achieved by working with an overflow valve and a control valve.The compressibility of each spring is extrapolated by calculating the shift pressure.Then the throttling area is calculated from the flow rate and the pressure,and the pressure loss is obtained according to the pressure curves.Finally,a calculation and check of the press control valve are carried out. |
