Problems solved by technology
[0004] However, the cost of the brake control unit with microcomputer function is very high, and the railway electric engineering vehicle itself does not have high requirements for the performance of the brake. The waste of other functions of the system will increase the manufacturing cost of the whole vehicle and reduce its market competitiveness

The invention discloses an air-electric hybrid brake system and an air brake control device thereof. The air brake control device comprises a first proportion electromagnet, a second proportion electromagnet, a valve and a valve rod, the first proportion electromagnet and the second proportion electromagnet are connected with a first controller and a second controller respectively, the valve is provided with an air inlet cavity, an air outlet cavity and an exhaust cavity, an air supply valve port is arranged between the air inlet cavity and the air outlet cavity, an exhaust valve port is arranged between the air outlet cavity and the exhaust cavity, the valve rod penetrates the air inlet cavity, the air outlet cavity and the exhaust cavity, a first end and a second end of the valve rod are connected with the first proportion electromagnet and the second proportion electromagnet respectively, and an air supply valve spool and an exhaust valve spool are arranged in the middle of the valve rod. When pressure is increased, the air supply valve port is opened, and the exhaust valve port is closed. When the pressure is reduced, the air supply valve port is closed, and the exhaust valve port is opened. Therefore, air brake force is changed along with electric brake force, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of rail electric engineering vehicles, in particular to an air-electric hybrid braking system and an air braking control device thereof. Background technique [0002] For rail electric engineering vehicles, the full use of electric braking is one of its main advantages over internal combustion engineering vehicles. The electric braking energy converts the kinetic energy of the engineering vehicle into electric energy, which can not only generate the braking force required for greater deceleration, but also reuse the energy during braking. However, factors such as the running speed of the engineering vehicle directly affect the size of the electric braking force. Therefore, supplementary braking is required when air braking force is required. This kind of braking mode that preferentially uses electric braking force and air braking force as a supplement is called air-electric hybrid braking. Rail electric eng...
