Abstract
The shift control mechanism is very important in the whole transmission assembly
components, which directly is related to the shift performance, drive handling,
dynamic performance, and fuel economy. Good shift process may bring us the driving
pleasure, and at the same time it can help to smooth the power transmission, improve
comfort. By taking one kind of light-vehicle shift control mechanism as an example
here, this paper shows the process of three-dimensional modeling and simulation, as
well as the basic design process of shift control mechanism, the application of
ergonomics, the evaluation method of the shifting process. Use CATIA to establish the
3D model and the basic structure statics analysis. Base on the multi-body dynamics
software ADAMS to do the kinematics. This paper has done some help to the
development of the product.
