The purpose of this study is to keep the similarity map in a certain position, so as to achieve flexible rotation, In order to reduce the wear rate, the synchronous technology of manual acceleration oil supply for automobile is also provided.In order to achieve tactical objectives,This study is similarity mapping.In the automobile water vapor shorthand composed of similarity, vanilla and ultra-thin, etc,An appropriate protrusion is formed on the inner side of the similarity map, and on both sides of the similarity base, in order to be able to insert into the position corresponding to the protrusion, a relatively longer and deeper insertion red than the protrusion is formed. Provide the synchronous device of water gate for automobile.
