Abstract: A labyrinth sealing device for reducing gas intrusion is provided. A sealing bush is provided with a jet hole at the front of a tooth tip gap. The jet hole faces a tip of a corresponding sealing tooth. A gas flow injected by the jet hole suppresses hot gas flowing into the tooth tip gap. The sealing bush is provided with a first intercepting member at the rear of the tooth tip gap, and the sealing tooth is provided with a second intercepting member at the rear of the tooth tip gap. The first intercepting member hinders hot gas flowing against an inner wall of the sealing bush, and the second intercepting member hinders hot gas flowing against the sealing tooth, such that a part of the hot gas flows in a reverse direction and is violently mixed with subsequent hot gas.

Abstract: Disclosed are a drive-by-wire chassis cyber-physical system under an intelligent traffic environment and a control method. The system includes: an SoS-level CPS, a system-level CPS, and a unit-level CPS, data transmission is realized between a plurality of unit-level CPSs and one system-level CPS, and data transmission is realized between a plurality of system-level CPSs and one SoS-level CPS. The system integrates a hub motor with a suspension, cancels traditional structures such as an engine and a clutch, and simplifies the structure of a chassis. A motor directly drives a vehicle to run, and different driving, braking or torque is applied to different wheels through four hub motors, so as to meet independent control of the wheels and improve active safety and operational stability.
