Embodiment 1

[0048] This embodiment provides an electric braking system, which is applied to railway wagons, and railway wagons include vehicles, such as figure 1 As shown, the system includes: a train control subsystem 100, a power transmission and signal transmission subsystem 200, and a vehicle braking subsystem 300, wherein the power transmission and signal transmission subsystem 200 is used to transmit electric energy and transmit control signals;

[0049] The train control subsystem 100 includes:

[0050] The main control unit 101 is configured to generate a braking control command, and send the braking control command to the vehicle braking control unit through the power transmission and signal transmission subsystem 200;

[0051] Vehicle braking subsystem 300 includes:

[0052] The load sensor 301 is used to detect the load of the vehicle and feed back the load of the vehicle to the vehicle brake control unit;

[0053] a vehicle braking control unit 302, configured to generate a ...

Embodiment 2

[0085] Based on the same inventive concept as in Embodiment 1, Embodiment 2 of the present invention provides a railway freight car, including a car body, a bogie, and a coupler buffer device. The railway freight car also includes the electric braking system described in Embodiment 1. The driving system is arranged on the vehicle body.

[0086] Specifically, the car body is the main body of a railway freight car, which is a container for cargo, and the bogie is the running part of a railway freight car, mainly used to support the car body, turn and brake, so as to ensure that the vehicle can run smoothly on the track . The coupler buffer device is the connection device between the vehicles, which can make the vehicles connected to each other to form a train, and can ease the longitudinal impulse between the vehicles. As an option, the railway may also include vehicle internal equipment, such as equipment for fixing cargo, equipment for loading and unloading cargo, and refrige...

Embodiment 3

[0089] Based on the same inventive concept as in Embodiment 1, Embodiment 3 of the present invention provides a railway freight car, including a car body, a bogie, and a coupler buffer device. The railway freight car also includes the electric braking system described in Embodiment 1. The moving system is set on the bogie.

[0090] In this embodiment, the electric braking system is set on the bogie, see for details image 3 , the electric braking system includes a train control subsystem (101), a power transmission and signal transmission subsystem (a whole composed of 201, 202 and 203) and a vehicle braking subsystem (a whole composed of 301, 302, 303, 304 and 305) , wherein the specific structure and composition of the electric braking system have been described in detail in the first implementation, so it will not be repeated here, and all the electric braking systems and their denaturation in the first implementation belong to the protection scope of this embodiment.

Abstract

The embodiment of the invention provides an electric brake system, a railway wagon and a brake method thereof. The electric brake system comprises a train control sub system, a power transmission andsignal transmission sub system and a vehicle brake sub system, wherein the train control sub system comprises a main control unit used for generating a brake control instruction and then transmittingthe brake control instruction to a vehicle brake control unit; the vehicle brake sub system comprises a load sensor, the vehicle brake control unit, a brake unit and a brake executing unit, wherein the load sensor is used for detecting load of a vehicle and then feeding back the load of the vehicle to the vehicle brake control unit; the vehicle brake control unit is used for generating a vehicle brake control instruction according to the brake control instruction and the load of the vehicle and then transmitting the vehicle brake control instruction to the brake unit; the brake unit is used for converting electric energy into mechanical energy according to the vehicle brake control instruction to provide a corresponding brake thrust; and the brake executing mechanism is used for executingbrake operation according to the brake thrust. According to the electric brake system, the technical problem of poorer brake performance in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of railway freight cars, in particular to an electric braking system, a railway freight car and a braking method thereof. Background technique [0002] Railway wagons are vehicles for completing railway cargo transportation tasks, and the braking system of railway wagons, as the execution structure for deceleration and parking of railway wagons, is an important part of railway wagons, and the technical status of the braking system directly affects the vehicle safe operation. [0003] In the prior art, the braking method usually adopted is air braking. An air compressor is provided on the locomotive, which compresses the air and stores it in the main air cylinder. The braking system is connected in series. When each vehicle needs to brake, the driver pushes the brake valve to the brake position to exhaust the air to reduce the air pressure in the train pipe. When the pressure of the auxiliary air cylinder o...
