Abstract

A coupling structure of suspension may include an assist knuckle, a RevoKnuckle rotatably engaged with the assist knuckle, rotated independently from the assist knuckle, and performing steering of a wheel located at an outermost periphery, a steering input portion fixed to a vehicle body and applying a steering force to the RevoKnuckle during steering, a rotation transfer unit located between and coupled between the RevoKnuckle and the steering input portion and absorbing angular displacement formed between the steering input portion and the RevoKnuckle, a first link unit having one end located on one side surface of the assist knuckle and the other end located at a lower end of the RevoKnuckle, and a second link unit having one end located on the other side surface of the assist knuckle and the other end located adjacent to the other end of the first link unit at the lower end of the RevoKnuckle.

Dependent claims

A coupling structure of a suspension, the coupling structure comprising:

an assist knuckle in which a strut part is mounted;
a RevoKnuckle rotatably engaged with the assist knuckle, rotated independently from the assist knuckle, and configured to perform steering of a wheel;
a steering input portion engaged to the RevoKnuckle and configured to apply a steering force to the RevoKnuckle during the steering of the wheel;
a rotation transfer unit coupled between the RevoKnuckle and the steering input portion and configured to absorb angular displacement formed between the steering input portion and the RevoKnuckle;
a first link unit having one end portion mounted on a first side surface of the assist knuckle and another end portion mounted at a lower end portion of the RevoKnuckle;
and
a second link unit having one end portion mounted on a second side surface of the assist knuckle and another end portion mounted adjacent to another end portion of the first link unit at the lower end portion of the RevoKnuckle.
