Switchable cross-connected and uncoupled hydraulic suspension modes balance travel stability with lower frame twisting on uneven dumping ground.
An H-frame suspension replaces lower torque rods and anti-roll devices to cut weight and complexity while tuning roll stiffness.
A tuned section-area and wall-thickness ratio helps a tubular torsion beam keep bending rigidity while cutting weight.
A connecting link holds the trailing-arm support ends at fixed distance to prevent oversteer and improve rear wheel guidance under lateral load.
Hydraulic pressurizing devices replace reactive anti-roll bars, countering cornering roll while easing suspension packaging constraints.
A slotted main bar and movable sub-rigid member vary roll stiffness to improve turning stability, ride comfort, and cost.
