An acuator for a shift-by-wire system includes a drive motor installed inside a motor housing, the drive motor having a drive shaft, and a decelerator inside a decelerator housing coupled with the motor housing, the decelerator coupled to the drive shaft. The decelerator includes a sun gear connected to a first side of an eccentric part of the drive shaft, a ring gear engaged with the sun gear and fixed to the decelerator housing, an output shaft connected to a second side of the eccentric part, a first bearing coupled to one side of the eccentric part and supporting the sun gear, a second bearing coupled to the other side of the eccentric part and supporting the output shaft, and a power delivery unit coupled to the sun gear and the output shaft in a center region between the first and second bearings.In an embodiment an actuator includes a drive motor installed inside a motor housing, wherein the drive motor includes a drive shaft having a driving part fixed to a rotor of the drive motor, an eccentric part integrally connected to the driving part at a position off a shaft center of the driving part, and an elongated part elongated from the eccentric part with respect to the shaft center, and a decelerator inside a decelerator housing coupled with the motor housing. The decelerator is eccentrically coupled to the drive shaft and includes a sun gear rotatably connected to the eccentric part, a ring gear engaged with the sun gear and fixed to the decelerator housing, an output shaft rotatably connected to the elongated part, a first bearing coupled to the eccentric part and supporting the sun gear, a second bearing coupled to the elongated part and a power delivery unit coupled to the sun gear and the output shaft in a center region between the first bearing and the second bearing.

Actuator for shift-by-wire system

A shift by wire system may include a shifter assembly that is configured to generate an electrical manipulation signal by a driver's shifting operation, a shifter controller provided in the shifter assembly and configured of transmitting shift information according to the electrical manipulation signal, and an actuator controller which is mounted on a housing coupled with the shifter assembly, connected to the shifter controller, and applies a driving signal according to the shift information to an actuator.

An apparatus for locking a shift lever of an automatic transmission in a vehicle may include a shift lock cam including a position converting member and being connected with a brake pedal wherein the shift lock cam is pivotally coupled to a shift lever housing and elastically supported by a first elastic member, and a shift lock release lever that is pivotally coupled to the shift lever housing and elastically supported by a second elastic member, wherein one end of the shift lock release lever is selectively coupled to a shift lever body and the other end of the shift lock release lever is eccentrically coupled to the position converting member of the shift lock cam.

Apparatus for locking shift lever of automatic transmission in vehicle

A key interlock system of a vehicle equipped with an automatic transmission satisfies a condition of a key interlock system that allows a shift leverinserted in a P-range groove (Parking)to be shifted to other ranges (R-range, N-range, and D-range) only by turning a key inserted in a key hole of an ignition lock cylinderto 'ON', and a condition of a key interlock system that allows the key to be removed from the key hole of ignition lock cylinderonly when shift leveris positioned at P-range (Parking), by using a mechanical structure. Therefore, it is possible to achieve a key interlock system that can be manufactured at a low cost, does not make noise, and does not easily break down, as compared with electronic devices.
