Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 The method for determining the filling quantity of transmission lubricating oil shown includes:

[0028] The first step is to establish the transmission analysis model: in the CFD simulation analysis pre-processing software (such as HyperMesh), extract the inner cavity and various components of the transmission housing, remove the outer wall of the transmission housing, and make the transmission housing a closed whole , and then form a transmission analysis model for CFD simulation analysis of transmission gear churning oil (see figure 2 ).

[0029] The second step, component grouping: In the CFD simulation analysis pre-processing software, according to the analysis requirements, group the components in the transmission analysis model to facilitate subsequent viewing of temperature, lubricating oil distribution, etc.; can be divided into tr...

Abstract

The invention discloses a method for determining a lubricating oil filling amount of a transmission. The method comprises the steps of: establishing a transmission analysis model, grouping components, setting the rotating speeds of moving components, setting the lubricating oil filling amount, obtaining n+1 groups of analysis data I by simulation analysis and calculation, changing the lubricating oil filling amount for n times, obtaining n groups of analysis data I by simulation analysis and calculation, determining a first lubricating oil filling amount, setting the rotating speeds and the lubricating oil filling amounts of the moving components, obtaining m+1 groups of analysis data II by simulation analysis and calculation, determining a second lubricating oil filling amount, and finally determining the lubricating oil filling amount of the transmission. By adopting the method disclosed by the invention, before the transmission is made into a finished product, the lubricating oil filling amount of the transmission is determined quickly and efficiently, thereby reducing the test cost and resources.

Description

technical field [0001] The invention belongs to the technical field of automobile transmission development, and in particular relates to a method for determining the lubricating oil filling amount of the transmission. Background technique [0002] The filling quantity of lubricating oil in transmission is an important design index in the design of automobile transmission. On the one hand, if the amount of lubricating oil in the transmission is too small, the oil pump in the transmission will not be able to absorb the lubricating oil, the gears will be poorly lubricated, and the temperature of the gears and the housing will be higher than the design requirements (that is, the temperature of the gears and the housing will be higher than that of their respective materials. Allowable temperature) and other issues, ultimately make the reliability of the transmission not meet the requirements; affect the fuel consumption of the vehicle. Therefore, it is necessary to determine an...
