Description

A transmission lever structure of automatic vehicle

The present invention relates to a shift lever structure of an automatic transmission vehicle. More specifically, the structure of a shift lever operated for shifting of an automatic transmission vehicle is switched to an inhibitor switch to directly transmit a signal to the TCU through a switch function of the shift lever itself. The shift lever structure of the automatic transmission vehicle to be made.

In general, the inhibitor switch functions to transmit the shift stage (P-R-N-D-3-2-L) selected by the shift lever operated according to the driver's shift will as an electrical signal to the TCU. As shown in FIG. 1, when the driver manipulates the shift lever as shown in FIG. 1, each contact point corresponding to each shift stage PRND-3-2-L exists. Through the kinematic connection of the manual control lever and the manual control shaft, the contact point inside the inhibitor switch 2 is energized to transmit an operated shift stage signal to the TCU 30.

As described above, the inhibitor switch is a component that can be moved to each shift stage only by physical force from the outside. If the driver wants to shift from the P range to the R range, the shift lever is changed from the P range to the R range. When pulled into the range, the shift cable connected between the shifting lever and the manual control lever pulls the manual control lever from the P range to the R range, thereby rotating the selector switch of the inhibitor switch assembled to the manual control shaft. The contact of the P range drops and the contact of the R range is attached, so the shift from P to R occurs.

On the other hand, the gear shift stage generated from the manual control lever and the actuator switch by the driver's operation should be exactly matched.If the operation is not matched, the repair is not performed due to the start code, start-up, and the malfunction code generation of the normally operated inhibitor switch. And defects in assembly process defects due to incorrect assembly. These problems may be caused by a change in play of the shift cable, poor assembly of the manual control lever and the inhibitor switch, and poor synchronization between the selector lever of the inhibitor switch and the manual control lever.

The present invention has been made to solve the problems of the prior art, the object of the present invention is to eliminate the intermediate operating structure connected to the shift cable, the manual control lever and the manual control shaft in the kinematic transmission structure of the shift stage, the shift lever Its switch function provides an inhibitor switched structure of an automatic transmission lever for transmitting signals to the TCU.
