It is a non-independent suspension, but with an independent suspension performance.
1. The semi-independent suspension characteristics
From the structural point of view it belongs to the suspension of non-independent suspension letter, since the rocker arm around the longitudinal direction is a torsion beam with coarse welded together, from the performance point of view but the suspension, this suspension is achieved with greater stability of the whole trailer independent suspension performance. The main advantage of this so-called semi-independent suspension with a simple and practical structure, the smallest space, low manufacturing cost. And many shortcomings, such as bearing capacity difference, roll resistance is weak, poor damping performance, comfort limited. In general this semi-independent rear suspension applies to small and medium sized cars and SUV’s low-end suspension.
2. What semi-independent suspension is
We often hear a trailing arm suspension, it is a semi-independent suspension. Suspension trailing arm type suspension structure is designed specifically for a rear wheel, which is very simple configuration, swing above the trailing arm rigidly connected to the wheel to achieve the body or frame, and then to act as hydraulic shock absorbers and coil springs flexible connection, and a support body acts as a shock absorber, cylindrical or square cross member is connected to right and left wheels.
