In order to solve the problem of oil leakage from the high mast breather of a three wheel mini electric forklift truck, a 1.6 t electric forklift truck is taken as the research object to carry out working condition tests to simulate the practical use scenarios of users and to reproduce the oil leakage phenomenon of the fuel tank breather and the corresponding working conditions. The CFD flow field simulation analysis of the oil in the fuel tank is studied, and the analysis results are compared with the real vehicle test results to verify the accuracy of oil sloshing analysis. Finally, the breather is optimized and improved, and the results show that the improved breather does not show oil leakage in simulation analysis and test verification under oil leakage working condition, successfully solving the problem.

Through simulation and calculation of the wheel-side reducer of forklift trucks under extreme working conditions, it is found that the tangential displacement of its housing is large, and the reducer is at risk of oil leakage. In order to reduce the tangential displacement, the optimization design is carried out in terms of the specification, spacing and number of bolts for fastening the reducer housing to achieve the design target value to determine the design plan. The test bench is used to simulate the load situation of the reducer and to verify the physical reducer, and finally the sealing performance design of the reducer is determined, providing a basis for the sealing design of wheel-side reducers of forklift trucks.
