AI Technical Summary

Technical Problem

Traditional electric four-wheeled vehicles have a fixed lateral stabilizer bar connection structure, which cannot be adjusted according to the vehicle's usage, leading to problems such as aging and loosening that affect handling stability and driving safety.

Method used

It adopts an adjustable connection structure, including a hydraulic device and an electronically controlled proportional valve. The hydraulic device is controlled by the ECU to adjust the lateral stiffness of the stabilizer bar, and it is equipped with self-lubricating bearings and buffer pads to reduce friction and vibration, thus achieving dynamic adjustment.

Benefits of technology

It enables automatic or manual adjustment of the roll stiffness of the stabilizer bar according to the driver's intention and road conditions, improving handling stability and ride comfort, extending component life and reducing maintenance costs.

Abstract

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.
