Experimental and simulated studies on hydraulic buffering valve for ZF-4WG308 power-shift transmission

摘要

The structure and working principle of a hydraulic buffeting valve for a power-shift transmission ZF-4WG308 were studied comprehensively,and a model of the hydraulic buffering valve was developed with AMESim.A bench test was conducted on a buffeting valve for transmissions (ZF-4WG308) and the test results agree well with the simulated results.Further more,the influences of the key parameters of the valve on the buffering performance were also studied in details.
