CONTROL DEVICE FOR MANUAL TRANSMISSION

The present invention relates to a compact manual transmission control device of a cable type.

In general, a transmission is installed in a vehicle to convert engine power to an appropriate driving force. Transmissions are classified into manual transmissions, automatic transmissions, and continuously variable transmissions depending on the operation method. 1 is a view showing a conventional manual transmission control device, FIG. 2 is a view showing a part of a conventional manual transmission control device, and FIG. 3 is an enlarged view of main parts of the manual transmission control device of FIG. 2. 1 to 3, the conventional manual transmission control device includes a shift lever 1 mounted on the driver's seat, a shift cable 2 for transmitting the shifting operation of the shift lever 1, and a selection of the shift lever 1 Of the select cable (3) that transmits the operation, the shift lever (4) connected to the shift cable (2), the select lever (5) connected to the select cable (3), the select lever (5) and the shift lever (4) Control shaft 10 that rotates and advances in conjunction with operation, a control finger 12 fitted to the control shaft 10, a shift rail 20 composed of a plurality, and a shift rail 20 composed of a plurality And a shift lug 22 formed on each and selected by the control finger 12. The control shaft 10 is equipped with an interlock plate 14. The interlock plate 14 prevents the control finger 12 from being disengaged from the shift lug 22 when the control shaft 10 is linearly moved. The shift lug 22 is composed of a plurality of shift lugs such as 1/2, 3/4, 5/6, and reverse stages, and is selected by the control finger 12 when selecting. The operation of the conventional manual transmission control device is performed as follows. When the driver performs the selecting operation by operating the shift lever 1, the selector lever 5 linearly moves the control shaft 10 in the axial direction according to the movement of the selector cable 3. When the control shaft 10 moves linearly, the control finger 12 also moves while being fitted to the shift lug 22 of the shift stage among the shift lugs 22 composed of a plurality. Then, when the driver performs the shifting operation, the shift lever 4 operates the control shaft 10 according to the movement of the shift cable 2. When the control shaft 10 rotates, the control finger 12 moves the selected shift lug 22. The shift lug 22 operates the synchronous device of the transmission 4 so that the shift operation is performed.
