Abstract

The invention discloses an electric disc brake cooling device and a method thereof. The electric disc brake cooling device comprises a shell and a disc body arranged in the shell. The shell is provided with a telescopic device connected with a controller. The telescopic device is connected with a friction device. The friction device comprises a conical friction wheel and a steering mechanism. Theaxial length of the conical friction wheel is 25%-35% of the radius of the disc body, and is arranged close to the outer periphery of the disc body. The conical friction wheel is connected with a rotation device through the steering mechanism and a transmission mechanism. The rotation device is provided with a fan blade which points to one side of the disk body. The conical friction wheel rotates,to drive the rotation device and the fan blade to rotate through the steering mechanism and the transmission mechanism. The electric disc brake cooling device can utilize braking energy to cool a braking mechanism, can also achieve an auxiliary braking effect in emergency braking, and has high practical value.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an electric disc brake cooling device and a method thereof for new energy automobiles. Background technique [0002] The development trend of automobiles, especially new energy vehicles, is intelligence. Active braking, as an important part of intelligence, is a development trend. Due to the high speed-up performance of new energy vehicles, the braking frequency will be greatly increased. During the braking process, a large amount of heat will accumulate, causing the brake disc and other brake components to be overheated, resulting in thermal deformation, deteriorating the braking ability, reducing the vehicle control force, and even causing the brake to fail. In addition, brake pads and the like will deteriorate under high temperature conditions for a long time, causing potential safety hazards and shortening the service life. Secondly, in the autom...
