Title:
METHOD AND DEVICE FOR DEICING BRAKE DISK
Document Type and Number:
WIPO Patent Application WO/2020/108397
Kind Code:
A1
Abstract:
A method and device for deicing a brake disk, which are applied in the technical field of rail vehicles. The method comprises: determining whether a rail vehicle enters a preset high-temperature environment under a preset low-temperature vehicle condition within a first duration; if braking is not performed within the first duration when the vehicle enters the preset high-temperature environment under the preset low-temperature vehicle condition, it may be determined that the brake disk has been iced over, that is, a brake mechanism may be controlled to brake at a preset braking pressure. Without affecting the driving of the vehicle, friction is used to generate heat for removing ice from a surface of the brake disk, thereby ensuring that the brake disk has a good braking effect when a driver is actually decelerating or stopping, which thus ensures the safe operation of the rail vehicle.
