    • A disc brake assembly (10) includes a stationary member (12), a rotating member (14) defining an axis of rotation (20), a plurality of stationary discs (28) spaced axially along the axis of rotation within the stationary member, and a plurality of movable discs (30) interspaced with the stationary discs. A brake coupler (24) supports the movable discs. During non-braking vehicle operation, the movable discs and the brake coupler remain stationary relative to the stationary discs. During a braking maneuver, the coupler couples the movable discs to the rotating member such that the movable discs are caused to rotate with respect to the stationary discs. Once the coupler and rotating member are interconnected a piston (60) moves the stationary and movable discs together to reduce rotation of the rotating member and brake the vehicle. Once the braking maneuver is completed, a first return spring moves the stationary and movable discs apart and a second spring (38) disengages the coupler from the rotating member to return the movable discs to their original position. This eliminates undesirable drag that occurs between stationary and rotating discs in a disc brake during non-braking vehicle operation.
    • 本发明涉及一种盘式制动器组件(10),其包括固定构件(12),限定旋转轴线(20)的旋转构件(14),多个固定盘(28) 和与固定盘间隔开的多个可动盘(30)。 制动器连接器(24)支撑可动盘。 在非制动车辆操作期间,可动盘和制动联接器相对于固定盘保持静止。 在制动操作期间,联接器将可动盘联接到旋转构件,使得可动盘相对于固定盘旋转。 一旦联接器和旋转构件互连,活塞(60)将静止和可动盘一起移动,以减少旋转构件的旋转并制动车辆。 一旦制动操作完成,第一复位弹簧将固定盘和可移动盘移开,并且第二弹簧(38)将联接器与旋转构件分离,以将可移动盘返回到它们的原始位置。 这消除了在非制动车辆操作期间在盘式制动器中的固定盘和旋转盘之间发生的不期望的阻力。
