Manual transmission control device{CONTROL DEVICE FOR MANUAL TRANSMISSION}

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

In general, a transmission is installed in a vehicle to convert the power of the engine into an appropriate driving force. Transmissions are divided into manual transmissions, automatic transmissions, and continuously variable transmissions according to their operating method. 1 is a view showing a conventional manual transmission control device, Figure 2 is a view showing a part of the conventional manual transmission control device, Figure 3 is an enlarged view of the main part of the manual transmission control device of FIG. 1 to 3, in the conventional manual transmission control device, a shift lever (1) mounted on a driver's seat, a shift cable (2) transmitting a shifting operation of the shift lever (1), and selection of the shift lever (1) Of the select cable (3), 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). The control shaft 10 for rotating and forward movement in conjunction with the operation, the control finger 12 fitted to the control shaft 10, a plurality of shift rails 20, a plurality of shift rails 20 And a shift lug 22 which is respectively formed in and is selected by the control finger 12. An interlock plate 14 is mounted on the control shaft 10. The interlock plate 14 prevents the control finger 12 from being separated from the shift lug 22 when the control shaft 10 moves linearly. The plurality of shift lugs 22 are composed of shift lugs such as 1/2, 3/4, 5/6, and reverse, and are selected by the control finger 12 during the selecting operation. The operation of the conventional manual transmission control device is performed as follows. When the driver operates the shift lever 1 to perform the selecting operation, the selector lever 5 moves the control shaft 10 linearly 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 and is fitted into the shift lug 22 of the corresponding shift stage among the plurality of shift lugs 22. Thereafter, when the driver performs a 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 synchronizing device of the transmission 4 to perform a shift operation.

However, since the conventional manual transmission control device is large and complex, the vibration of the transmission or the road surface is transmitted to the shift lever of the driver's seat, and thus the shift feel is not good.

On the other hand, the present invention is to propose a mechanism to improve the sense of shift by making the manual transmission control device compact so that the vibration of the transmission or the road surface is not transmitted to the shift lever of the driver's seat.
