Automatic transmission lever assembly having shift-lock cam using electromagnet

摘要

Disclosed therein is an automatic transmission lever assembly having a shift-lock cam having an electromagnet. The automatic transmission lever assembly includes: a base bracket fixed to a frame of a vehicle; a rod; a rotating member joined to a lower end of the rod, the rotating member rotating on a predetermined shaft according to a movement of the rod for changing a transmission mode and having a locking portion formed at a position corresponding to a shift-lock; a shift-lock cam having a permanent magnet, the shift-lock cam being caught to the locking portion at a shift-lock position and being rotatable on the shaft; and an electromagnet provided at a position facing the permanent magnet, wherein when a brake signal is transferred, electric current flows to the electromagnet, so that the shift-lock cam is operated in a direction to be released from the locking portion.

1. An automatic transmission lever assembly, comprising:
a base bracket fixed to a frame of a vehicle; a rod; a rotating member joined to a lower end of the rod, the rotating member rotating on a first shaft according to a movement of the rod for changing a transmission mode and having a locking portion formed at a position corresponding to a shift-lock; a shift-lock cam having a first arm caught to the locking portion to prevent rotation of the rotating member and a second arm to which a permanent magnet is attached, the shift-lock cam being caught to the locking portion at a shift-lock position and being rotatable on a second shaft; and an electromagnet having a noise preventing pad to be contacted with the second arm and provided at a position facing the permanent magnet, wherein when a brake signal is transferred, electric current flows to the electromagnet, so that the first arm and the second arm of the shift-lock cam rotate on the second shaft in a direction where the locking portion is released.
