DISK BRAKE AND HOLD-DOWN SPRING OF SUCH A DISK BRAKE Russian patent published in 2018 - IPC F16D65/97 

FIELD: machine building.

SUBSTANCE: group of inventions relates to automotive industry. Disc brake comprises a leaf hold-down spring that presses a hold-down device. Hold-down spring is designed to be symmetrical with respect to its transverse plane and has two spring arms. Both spring arms have an opening respectively, into which one lug passes on the hold-down device respectively. Each spring arm has a first region to which adjoins the corresponding rod of the hold-down clamp with a clamp, and a second area that adjoins the hold-down device with a clamp. Hold-down spring, by the type of the tray, surrounds each of the two rods of the hold-down clamp, wherein both of the first regions of the spring arms forming the corresponding bottom of the tray. Tray is asymmetric due to the fact that the height of the tray wall on the side of the middle region corresponds approximately to the corresponding diameter of the corresponding rod, while the height of the tray wall on the side facing away from the middle region is maximum a half of the specified height.

EFFECT: ensuring optimal damping is achieved.
