| 摘要 | A parallel beam brake apparatus for dual and triple axle trucks and a single beam brake apparatus for single axle trucks each comprise spaced, pivotably mounted bell crank levers (30) which engage a fluid operable actuator (38) between one pair of arms (32) and engage a pair of push rods (58) with the remaining arms (34). Improved spherical joints (60) between the arms and the push rods facilitate force transmission without allowing push rod rotation. A unique pivot geometry between the bell crank levers and the brake beams facilitates assembly and improves stress distribution between the levers and the beams. The actuator (38) includes a slack adjustor mechanism (40) in which a spiral power spring unwinds to drive a lead screw and take up slack or is wound by the rotating, translating lead screw to add slack. | ||||||
