Varying frictional torque in a disc brake by varying frictional contact area
A car or bicycle disk-braking device has a pair of friction pads 46 having a predetermined area, which can clamp or release a disk 12 to reduce or stop rotation. The portion of the disk 12 passing between the friction pads 46 has a varying frictional contact area. In one embodiment, the varying area...

| description | A car or bicycle disk-braking device has a pair of friction pads 46 having a predetermined area, which can clamp or release a disk 12 to reduce or stop rotation. The portion of the disk 12 passing between the friction pads 46 has a varying frictional contact area. In one embodiment, the varying area is formed by a series of spaced openings 22 having a circular or oval shape (22, fig 3). The opening spacing is said to be predetermined, and opening surface areas of parts of the series may increase or decrease by a constant ratio. The area of each opening 22 is smaller than that of the friction pads 46. Another embodiment has a frictional contact area with periodically changing boundary radii (fig 5). As the vehicle brakes, a periodic variation of the friction torque is generated which is said to prevent the wheels from sliding similar to an anti-lock braking system. |
