Abstract

The invention relates to an electrically-controlled air braking device of a flat-plate transport vehicle, which belongs to the field of flat-plate transport vehicles. The device is provided with an electronic braking pedal and is characterized in that: the electronic braking pedal is electrically connected with a controller; the controller is electrically connected with a communication bus and outputs a braking signal for controlling a proportional reducing valve to act; the proportional reducing valve is connected with a relay valve through a bi-pass one-way valve; the outlet of the relay valve is communicated with a braking air chamber; the braking air chamber is provided with a pressure sensor; and the pressure sensor is electrically connected with the controller. The device has a simple structure, simplifies the management arrangement of an air control system of the flat-plate transport vehicle as well as a parallel operation braking control system and enhances parallel operation safety.

Description

technical field [0001] The invention relates to the field of flatbed transport vehicles, in particular to an electronically controlled pneumatic brake device for flatbed transport vehicles, which is used for braking the flatbed transport vehicles. Background technique [0002] As we all know, the flatbed transport vehicle is a large-scale transportation equipment, which can complete the handling of large-scale and heavy goods. It can be used for road transportation of large-scale equipment (cargo), sequential transportation of hull segments in shipyards, and steel plates in steel plants. Transfer of steel pipes. [0003] Pneumatic braking system is commonly used in flatbed trucks. Generally, the foot brake pedals installed in the front and rear cabs generate control air pressure, and drive the air chamber of the brake bridge through the relay valve to push the brake drum to achieve service braking. Due to the long length of the flatbed transport vehicle, the front and rear...
