DISK BRAKE AND HYDRAULIC JACKET FOR IT Russian patent published in 2011 - IPC F16D65/853 

FIELD: machine building.

SUBSTANCE: hydraulic jacket of disk brake consists of circular case. The circular case has a multitude of concentric channels. The first axial channel has a hydraulic connection with the first channel out of said multitude of concentric channels. The second axial channel has a hydraulic connection with the second channel out of the said multitude of concentric channels. The second channel is separated from the first channel with the third channel out of the multitude of concentric channels. According to the first version the circular case of the hydraulic jacket consists of a radial channel between the first and second axial channels, and of an entry for liquid connected to the radial channel. Direct flow of liquid from the radial channel into the third channel along axis is excluded. According to the second version the circular case of the hydraulic jacket consists of the third channel hydraulically connected with one of the first or second axial channels. Diameter of one axial channel runs across a portion of radial length of the third channel and a portion of radial length of corresponding one of the first or second channels out of the said multitude of the concentric channels. The brake consists of a stationary jacket, of a driven shaft, of the first friction disk, of the second friction disk and of a pressure plate. The first friction disk has a hydraulic jacket. The brake according to the first version has the hydraulic jacket made according to the first version. The brake according to the second version has the hydraulic jacket made according to the second version.

EFFECT: balanced flow of cooling liquid through channels of hydraulic jacket for disk brake; efficient removal of heat from disk brake.
