Rear suspension for three-wheeled car
First Claim
1. A rear suspension of a three-wheeled car with two front wheels and one rear wheel in a car frame comprises:
- a wheel center to which a rotation axis of the one rear wheel is rotatably coupled;
an upper link with one end pivotally connected to a car body and the other end pivotally connected to one portion of the wheel center; and
a lower link with one end pivotally connected to the car body below the one end of the upper link and the other end pivotally connected to the other portion of the wheel center below the other end of the upper link;
wherein, the upper link and the lower link are installed to the car body so that the one end of the upper link is positioned higher than the other end thereof, and the one end of the lower link is positioned higher than the other end thereof;
wherein an angle of inclination from the ground between the one end and the other end of the lower link is greater than an angle of inclination from the ground between the one end and the other end of the upper link;
wherein the upper link includes a first upper link pivotally connected to one lateral side of the wheel center and a second upper link pivotally connected to the other lateral side of the wheel center to be symmetric to the first upper link, the first upper link and the second upper link being installed to perform a four-bar linkage movement with the car body and the rear wheel;
wherein the lower link includes a first lower link pivotally connected to one lateral side of the wheel center and a second lower link pivotally connected to the other lateral side of the wheel center to be symmetric to the first lower link, the first lower link and the second lower link being installed to perform a four-bar linkage movement with the car body and the rear wheel; and
wherein a first instantaneous center situated on intersection of extensions of the first upper link and the second upper link, and a second instantaneous center situated on intersection of extensions of the first lower link and the second lower link, are located to the rear of the rotation axis of the rear wheel.
