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.

An apparatus and methods are provided for a rear portal trailing arm assembly for a vehicle rear suspension. The trailing arm assembly comprises a CV joint hub for coupling with a transaxle and a wheel hub for coupling with a rear wheel. A gear transfer case extends rearward from the CV joint hub to an axle case and functions similarly to a rear trailing arm. Forward mounts facilitate coupling the gear transfer case to the chassis such that the trailing arm assembly pivots vertically with respect to the chassis. A rearward mount facilitates coupling a strut with the gear transfer case to control the vertical motion of the rear wheel. Multiple gear assemblies are meshed within the gear transfer case. An axle is coupled with the meshed gear assemblies and housed within the axle case, such that torque applied to the CV joint hub is communicated to the wheel hub.

The present disclosure relates to a front chassis system of a tilting vehicle, and a front chassis system of a tilting vehicle. The system includes at least: a front swing arm-LH connected to and provided at a vehicle body and a front steering wheel-LH, and a front swing arm-RH connected to and provided at the vehicle body and a front steering wheel-RH; a front shock absorber-LH connected to and provided at the front swing arm-LH, and a front shock absorber-RH connected to and provided at the front swing arm-RH; a front tilt bar rotatably connected to and provided at the vehicle body, and connected to and provided at the front shock absorber-LH and the front shock absorber-RH; at least one front elastic roller provided at the vehicle body; and a steering device linked to and provided at a steering wheel part assembled on the vehicle body.

A suspension joining structure may include a lower arm which has one end portion fastened to a vehicle body, an assist knuckle on which a strut portion is located, a fastening unit which is configured so that a second end portion of the lower arm and a lower end portion of the assist knuckle are fastened, a revoknuckle which is pivotally fastened to the assist knuckle to be rotated independently of the assist knuckle to perform the steering of a wheel, and a steering input portion fastened to the revoknuckle and configured to apply a steering force to the revoknuckle upon the steering of the wheel.

An independent drive module includes: an in-wheel motor configured to provide driving force to a wheel of a vehicle; a support arm including a first end connected to a vehicle body and a second end connected to the in-wheel motor, to support the in-wheel motor; a shock absorber module including a first end connected to the in-wheel motor and a second end connected to the vehicle body, the shock absorber being configured to absorb shock between the in-wheel motor and the vehicle body and swivel the in-wheel motor during turning of the vehicle so as to perform both shock absorption and steering; and a steering motor connected to the second end of the shock absorber module to transmit rotational force for the steering to the shock absorber module.
