Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shift lock apparatus for a vehicle transmission, and more particularly, to a shift lock apparatus for a vehicle transmission capable of implementing a shift lock function using a solenoid apparatus.
Generally, a vehicle transmission can have a different gear ratio to keep the rotation of the engine constant according to the speed of the vehicle, and the driver can operate the shift lever in the transmission to change the gear ratio of the transmission can do. The shift mode of the vehicular transmission includes a manual shift mode in which the driver can change the speed change stage and an automatic shift mode in which the shift mode is automatically changed in accordance with the speed when the driver selects the drive mode (D).
In addition, a sports mode type transmission capable of performing manual shifting and automatic shifting in one transmission is used. The sports mode type transmission may be implemented by a manual transmission performing the automatic shifting by raising or lowering the number of gears of the driver while performing automatic shifting in principle or by providing a transmission capable of automatic shifting next to the transmission performing manual shifting.
The shift lock function is a function developed to prevent the occurrence of a sudden accident frequently. It is basically a function of the shift lever of the shift lever in the "P" or " N "single-stop pedal to prevent the shift lever from moving to other positions, and a second shift to prevent the shift lever from moving to the" R "stage when the vehicle is moving forward beyond a certain speed It has a lock function. In order to prevent the driver from malfunctioning, a full shift lock function capable of shift lock can be implemented for all gear positions.
The shift lock function is performed by a solenoid device connected to the shift lever to inhibit the shift lever from moving. The solenoid device is used in various fields including a valve device, a mechanical device, a shift lock device of a shift lever of a vehicle, and the like by being applied to the operation of a valve or a lever by the action of an electromagnet.

Therefore, there is a demand for a means for increasing the service life of the shift lock device of the vehicular transmission and reducing the manufacturing cost.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a vehicular transmission that can improve the cumulative tolerance and noise by reducing the number of components of a damper and a fixed core of a shift lock device of a vehicular transmission. Lock mechanism.
According to an aspect of the present invention, there is provided a shift lock device for a vehicular transmission, comprising: a bobbin having a coil wound on an outer surface thereof so that a through hole formed therein is selectively magnetized; A fixed iron core fixed to one side of the through hole; A plunger disposed on the other side of the through hole and linearly moving in a direction parallel to the through hole depending on whether the through hole is magnetized; A damper fixed on the movement path of the plunger outside the bobbin; And a plunger arm having both ends connected to one end of the plunger and one end of a lock lever and having a slot into which the damper is inserted when the plunger is moved.
According to the shift lock apparatus of the vehicle transmission as described above, one or more of the following effects can be obtained.
First, by reducing the number of parts of the damper and the fixed iron core of the shift lock device of the vehicular transmission, it is possible to reduce scattering of cumulative tolerance and damper characteristics.
Second, since the damper of the shift lock device of the vehicular transmission is located outside the plunger (i.e., outside the bobbin), the lifetime of the damper can be prolonged without causing a hardening phenomenon due to heat generated in the coil.
Third, there is an effect that noise can be reduced through a damper provided in a shift lock device of a vehicle transmission.
The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.
