The invention relates to the field of automobile
brake systems, and discloses an air pressure EBS for a semi-trailer transport vehicle for
dangerous goods. The air pressure EBS comprises an EBS ECU, an automatic pressure regulating valve, a pressure
differentiator, a front
brake chamber, an electronically controlled
brake master valve, a double-chamber brake chamber, a wear sensor, a speed sensor, a steering
tire pressure sensor, and an emergency
cut-off valve control pipeline
pressure sensor. The brake chamber is connected to the automatic pressure regulating valve, the electronically controlled brake master valve and an air tank in sequence through a pneumatic pipeline, and a pressure
differentiator is installed on the brake chamber. A semi-trailer brake handbrake is separately installed to control the braking force of the semi-trailer in the event of EBS electronic control failure. According to national requirements for semi-trailer transport vehicles for
dangerous goods, a tire blowout emergency safety device and an emergency
cut-off valve are included in the EBS monitoring range. The invention has important significance for improving the safety of semi-trailer transport vehicles for
dangerous goods.
