Description

Technical Field

[0001] The utility model belongs to the technical field of turning control, and more specifically, particularly relates to a turning control structure of a wire-controlled chassis. Background Art

[0002] Chassis-by-wire is a technology that transforms the signal conduction mechanism of the automobile chassis into wire-controlled one, replacing traditional mechanical signal conduction with electrical signal conduction. Steer-by-wire eliminates the mechanical connection components between the steering wheel and the steering wheel. In the steering-by-wire system, the driver's operating actions are converted into electrical signals through sensors. After analysis and processing, the signals are directly transmitted to the actuator through wires.

[0003] The existing wire-controlled chassis steering structure usually controls the steering of the front wheels, while the rear wheels always remain level with the vehicle body. When the rear wheels are not convenient to steer, the turning radius of the vehicle becomes larger, reducing the vehicle's maneuverability. In addition, the rear tires may be excessively worn due to the inability to steer, thereby requiring a control structure that can achieve simultaneous steering of the front and rear wheels.
