The utility model relates to the field of stabilizer bar, especially transverse stabilizer bar's adjustable connecting structure of four -wheel electric vehicle. The utility model discloses stabilizer bar, axle bush and pull rod, stabilizer bar is trapezoidal, and the both ends are punched into the ear piece, axle bush is covered in the middle part of stabilizer bar, and pull rod is provided with two, and is hinged in the both ends of stabilizer bar respectively, and pull rod is installed on the frame, and axle bush is connected with hydraulic device still, and the top of hydraulic device is fixed with bolt and set up on the frame. Axle bush connects hydraulic device, and is electrically connected with automobile ECU and is equipped with electric control proportional valve, can automatically or manually adjust the lateral stabilizer bar roll stiffness according to the intention of driver or road condition. When driving fiercely or high -speed driving, ECU controls electric control proportional valve to adjust hydraulic device output pressure according to sensor group feedback, and the roll stiffness is increased, and the control stability and high -speed driving safety are enhanced.

This invention discloses an interconnected molecular spring vehicle suspension, comprising an interconnected structure of several hydraulic chamber units and an oil reservoir unit. Each hydraulic chamber unit includes a hydraulic chamber, a piston rod, a damping module, and an oil supply pipe. The oil reservoir unit includes a molecular spring chamber, insulating rubber, and an oil tank. The piston rod is connected to the vehicle frame, and the oil tank is isolated from the molecular spring chamber by the insulating rubber. The molecular spring chamber is filled with water and a hydrophobic microporous material. When the piston rod is compressed downwards, the hydraulic oil in the hydraulic chamber flows into the oil tank through its damping module and the oil supply pipe. When the piston rod is extended, the hydraulic oil flows back into the hydraulic chamber under the elastic force of the molecular spring chamber. The molecular spring chamber provides vibration isolation, and the damping force generated when the hydraulic oil flows back and forth through the damping module dissipates vibration energy. The interconnected design simplifies the structure of the molecular spring suspension, enabling lightweight suspension and reducing suspension costs.
