Abstract:
An automatic compensation mechanism for brake unit, said brake unit involving a turning block installed inside an outer casing, on the outside of the outer casing being a swing member serving to drive the turning block, on the other side of the turning block inside the outer casing being a push block, said push block is driven by the turning block for parallel movement, on the other side of the push block being a brake block extending out of the outer casing, to perform brake operation on a brake disc; characterized in that: in the turning block is an automatic compensation mechanism, extending from the brake block toward the turning block is a bolt that is screwed onto the automatic compensation mechanism, at the rear of the push block being a floating member with an inner screw hole, on the other end of the floating member being a tooth plate, at the center of the tooth plate being a shaft rod, on the shaft rod being a driving plate and a cover hood, the driving plate being installed inside the turning block, at the rim of the driving plate being the formation of a series of guide grooves, on two sides of each guide groove being the formation of an arch groove section and a flat cut section, inside each guide groove being a roller, the arch groove section enabling the roller to rotate on its axis, the flat cut section working with the inside edge of the turning block to engage the roller, so the turning block can synchronously drive the driving plate to rotate, the cover hood restricting the roller in an area between the guide groove of the driving plate and the inside edge of the turning block, thereby comprising a brake unit with an automatic compensation function.
