<One Embodiment>
Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows an embodiment of a propulsion lever control system of a control device for an internal transmission according to the present invention. The internal transmission is provided with at least one planetary gear system and a control device that performs control corresponding to the set planetary gear system, and the control device is used to control power input of the planetary frame A or the internal gear R. A control unit C1, a control unit C2 used for controlling whether or not the sun gear is fixed, and a control unit C3 used for controlling the power output of the planetary frame A or the internal gear R are provided. The main emphasis of the present invention is that the propulsion lever 1, the propulsion lever 2 and the propulsion lever 3 of each control unit are controlled to be the same flat cam 4, and each propulsion lever 1, The displacement order of the propulsion lever 2 and the propulsion lever 3 is accurately linked, and each propulsion lever 1, the propulsion lever 2 and the propulsion lever 3 are operated by one cam, and the corresponding control unit C1, control unit C2, and The speed change function is achieved by switching the clutch by accurately controlling the control unit C3. The flat cam 4 is an axial flat cam, a radial cam, an internal cam, an external cam, or any cam similar to the cam, and the schematic and description of the present plan will be described by taking the axial flat cam according to the most preferred embodiment as an example. However, the embodiment of the cam of the present invention is not limited to this. The displacement trajectory of the propulsion lever is a left / right displacement trajectory, an upper / lower displacement trajectory, and a trajectory based on the rotation angle. Is not limited to this.

  FIG. 2 is a conceptual diagram showing a 5-speed planetary gear group provided by the present invention. The control unit C1 controls switching of the clutch for inputting the power of the planetary frame A or the internal gear R, and thereby controls switching of the input path of the shift for inputting the power of the planetary frame A or the internal gear R. The control unit C2 is used to control switching of the speed change path depending on whether or not the sun gear is fixed. The control unit C3 is used for controlling switching of the output path of the shift by the power output of the planetary frame A or the internal gear R. The speeds of the control units C1, C2, and C3 are arranged in order as shown in the chart of FIG. 3, and A of the control unit C1 is defined as O and R is defined as X. . S1 of the control unit C2 is defined as O and S2 is defined as X. A of the control unit C3 is defined as O, and R is defined as X, as shown in the chart of FIG.

  According to FIG. 4, the three control units C1, C2, and C3 are converted into one member to be in an ideal control state (see FIG. 5). The control unit C1, the control unit C2, and the control unit C3 according to the present invention may be used as long as the control order matches the cyclic order of OOOXXXX, and the order arrangement does not overlap. In actual operation, the control unit C1, the control unit C2, and the control unit C3 are simplified and become unnecessary, that is, the stroke is not used, so the five-speed shift is simplified to the two-speed or three-speed shift. When the switching path is selected without installing S2 and the control unit C2, the system is operated at a three-speed shift. Based on this principle, two or more sets of five-speed planetary gear systems have been expanded to form an embodiment in which two sets are operated, and the control effect of 5 × 5 = 25-speed shift is achieved by controlling two members (planar cams 4).

Taking the above principle as an example, the left and right movements of each of the propulsion lever 1, the propulsion lever 2 and the propulsion lever 3 are O on the left and X on the right (see FIG. 4), and the trajectory shown in FIG. By rotating one flat cam 4 (that is, orbital rotation), each propulsion lever 1, propulsion lever 2 and propulsion lever 3 are rotated to corresponding positions according to the trajectory, and each propulsion lever is in the right and left lateral directions. The shift function is controlled by switching the clutch of each control unit C1, control unit C2, and control unit C3. The rotation when the flat cam 4 is operated is selected from a reel, electric drive, or the like.
