Motion Control Beam (MCB)
Engineered for superior chassis stability, the MCB employs a precision circular disc spring to distribute and absorb external impact forces.
Its elastic friction plate deforms under load and rebounds smoothly to absorb shock energy, while controlled friction between the plate and cylinder generates natural damping.
The result is enhanced body rigidity, reduced vibration, and a more confident, composed driving experience.

There are girders & drive shaft support in the chassis for general RV engine designing of main Structure. But the top of the suspension system is only fixed by the body sheet metal, and the difference between the upper and lower support strengths is too large, so one is installed at the engine room body sheet metal fixed suspension system. The vehicle upper and lower structure could be more perfect and improve safety.
The front wheel suspension system of the RV is independently suspended for maximum cushioning, but the transmission of residual power is ultimately absorbed by the car body. It is easy to cause unilateral effort, using the balance bar to transmit the force of the single-sided independent suspension system to the other side, and it is transmitted at the same time. When the two sides are evenly stressed, the comfort is naturally increased, and the driving control is more flexible.
