Single cross arm independent suspension
Single-arm independent suspension refers to the suspension in which each side wheel is hinged with the frame through one arm and the wheel can only bounce in the transverse plane of the car. The single-arm independent suspension structure has only one arm, the inner end of which is hinged on the frame (body) or axle housing, the outer end is connected with the wheel, and the elastic element is installed between the body and the arm. The half-shaft bushing is disconnected and the half-shaft can swing around a single hinge. The elastic element is the coil spring and the oil-gas elastic element which can adjust the horizontal action of the body together to bear and transmit the vertical force. The longitudinal force is borne by the longitudinal stinger. Intermediate supports are used to bear lateral forces and part of longitudinal forces
Double cross - arm independent suspension
The difference between the double horizontal arm independent suspension and the single horizontal arm independent suspension is that the suspension system is composed of two horizontal arms. Double cross arm independent suspension and double fork arm independent suspension have many similarities, but the structure is simpler than double fork arm, it can also be called a simplified version of double fork arm suspension
