Title The Design of Manual Transmission System
Abstract
Transmission is an important component of automobile transmission system, and effects the vehicle dynamic performance, fuel economy, handling stability, reliability and efficiency directly.Manual mechanical transmission has the disadvantages of large volume, inconvenient operation, big shifting impact and so on, but it is also characterized by its high transmission efficiency, low manufacturing cost, high reliability and simple structure. So it gets widely used in modern cars.
This paper explains the working principle of transmission input and output shaft, and analyses the power transmission line through the design of manual transmission system. Once transmission design scheme is determined, transmission ratio can be determined and the parameters of the main parts of gearbox can be designed and calculated according to the design parameters of the full vehicle.Finite element analysis of the gear and shaft in a certain gear were carried out and compared with the calculated results. The final part of the design reorganizes all determined parameters, and draws 2D engineering drawings and 3D model of input and output shaft.
Keywords manual transmission input shaft out shaft transmission ratio finite element analysis
