Anti-lock brake disc with heat pipe type air duct

Abstract

The invention discloses an anti-lock brake disc with a heat pipe type air duct, and relates to the technical field of automobile part production and design. The anti-lock brake disc comprises a fixingshaft sleeve and a floating wheel disc, wherein the fixing shaft sleeve and the floating wheel disc are mutually clamped, connected and rotationally matched, and driving protruding blocks and blocking pieces are arranged between the fixing shaft sleeve and the floating wheel disc. According to the anti-lock brake disc, the blocking pieces and the driving protruding blocks are arranged, the driving protruding blocks and blocking blocks are used for being in contact fit so as to form a single-pole gear structure between the fixing shaft sleeve and the floating wheel disc, the fixing shaft sleeve arranged on the surface of a wheel frame drives the protruding blocks to push the blocking pieces to drive the floating wheel disc to rotate, during braking, a caliper clamps the floating wheel disc, air inside an expansion cavity expands to eject out expansion bolts due to heat generated by friction, and the blocking blocks support and block the driving protruding blocks, so that the fixing shaft sleeve is forcibly braked, but the impact force between the blocking blocks and the driving protruding blocks is larger than the supporting force of the expansion bolts, in the braking process, thebraking distance is from short to long, and the locking phenomenon is avoided.

Description

technical field [0001] The invention belongs to the technical field of production and design of automobile parts, in particular to an anti-lock brake disc with a heat pipe type air duct. Background technique [0002] The brake disc is the disc brake disc, which is a necessary braking part in the car. The working mechanism of the existing common disc brake disc is often to fix a disc on the wheel frame and rotate synchronously with the wheel frame. When the caliper clamps When the disc is tightened, the disc will be decelerated and the tire will be decelerated; however, in this structure, the caliper spans both sides of the disc. During the clamping process, it is very easy to experience uneven force, which in turn leads to uneven heating. The uneven expansion of the disc will easily cause the tire to vibrate and damage the disc during the deceleration process of the tire, and even cause an accident; the common solution to this is to replace it with a floating brake disc, whi...
