    - Double lever mechanism: This is the third inversion of four bar chain. It is used for transmitting oscillatory motion from one lever to another. Ackermann steering gear mechanism is an example of double lever mechanism.



    - Link 2 and 4 are in equal in length and are called as levers. These links oscillate whenever the vehicle takes a right turn.

    - If the vehicle turns towards right, the angle α increases as link 4 turns and on the other side when the link 2 turns it decreases the angle α. As link 2 and 4 oscillate, this mechanism is called as double lever mechanism or Ackermann steering gear mechanism.
