- Abstract
The secondary impact of automotive transmission and its adverse effect on the shift process has attracted widespread attention in the automotive industry. Based on comparing the defects of the asymmetric tooth structure widely used at present and expounding its application limitations, this paper puts forward a novel high-low tooth synchronizer with the characteristics of simple structure, easy to realize large-scale production, and not limited by the use position, in order to achieve the improvement purpose of reducing the secondary impact. And then, GSA test equipment is applied to test the feasibility of using the high-low tooth structure in the second gear in the synchronizer of a 6-gear manual transmission to reduce the secondary impact. The research results clearly indicated that the high-low tooth structure of vehicle synchronizer could effectively improve the secondary impact in the shift process of vehicle transmission, which provides a new research path for domestic and foreign transmission manufacturers to solve the secondary impact.
