Abstract

The invention provides a gear shifting mechanism in the vehicle transmission technical field, consisting of an input shaft welding-on part, an advancing gear piston, an advancing gear cylinder, a backing gear piston, a backing gear cylinder, a recovery spring, a composite spring, and an advancing gear clutch steel sheet, a friction sheet, a backing gear clutch steel sheet, a friction sheet, a planetary mechanism component and a sun wheel welding-on part which are sequentially overlapped. The steel sheet of the advancing gear clutch and the planetary frame are respectively connected with the input shaft by a spline; the friction sheet is connected with the sun wheel welding-on part by the spline; the steel sheet of the backing gear clutch is connected with a stepless transmission shell by the spline; and the friction sheet is connected with a sun wheel gear ring by the spline. The gear shifting mechanism has the advantages of compact structure, low cost, high transmission efficiency, reliability and stability.

Description

technical field [0001] The invention relates to a shifting mechanism, which belongs to the technical field of vehicle transmission. Background technique [0002] At present, most cars usually use the traditional mechanical shifting mechanism, that is, the combination of gears is used to achieve shifting, but due to the discontinuity of the gears, it is impossible to achieve smooth shifting and make full use of the efficiency of the engine. To achieve this goal, it is necessary to abandon the existing mechanical shift mechanism and replace it with a new type of continuously variable transmission mechanism. However, the metal belt structure of the continuously variable transmission cannot realize reverse gear and neutral gear, so a gear shift mechanism that can effectively realize this function must be assembled. Contents of the invention [0003] The technical problem to be solved by the present invention is: to solve the problems existing in the above-mentioned prior art,...
