Abstract

1,081,284. Disc brakes. DUNLOP CO. Ltd- Nov. 24, 1964 [Nov. 26, 1963], No. 47747/64. Heading F2E. In a disc brake, the brake disc 1 is formed with circumferentially extending recesses or apertures on the radial and/or dished central body portion of the brake disc to provide a labyrinthine path for the conduction of heat from the braking surfaces such that the heat follows a sinuous course to enable the disc and wheel hub to remain at a lower temperature at which expansion of the dished portion 2 and consequent deformation of the disc 1 is correspondingly reduced. In the embodiment shown in Fig. 1, the brake disc 1 is formed on opposite sides thereof, adjacent the dished central body portion 2, with annular rows of recesses 3, 4 in individual rows which are staggered in relation to the recesses in the other rows. The heat produced on braking is thus constrained to flow along a labyrinthine path in the direction of the arrows. In an alternative embodiment shown in Fig. 3, the dished central body portion 2 of the brake disc is formed on its outside with recesses 5 and on its inside with recesses 6 to provide the labyrinthine path shown by the arrows. It is stated in the Specification that a reduction in the squeal caused by one of the brake pads dragging against the brake disc is substantially eliminated by the above means.
