    • The coaster brake of this invention is provided with a clutch cone screw-fitted to a driving body which is driven by pedals, to be axially movable in correspondence with the driving body's turning direction, a brake cone supported through a clutch mechanism which is not turnable in the forward direction, but which allows its turning in the reverse direction, and a brake members which is operated to apply brake on the hub shell by the aforementioned clutch cone moving to approach the aforementioned brake cone side, when the driving body is turned in a reverse direction. When the hub shell is turning in the forward direction, the brake action may be exhibited by applying to the driving body reverse rotation similarly top conventional coaster brake. Besides, the aforementioned brake cone is rotatable in the reverse direction by means of the clutch mechanism and as the driving body is subjected to a reverse turning, when the hub shell is not turning in the forward direction, the aforementioned brake cone will turn in the reverse direction integrally together with the driving body, the clutch cone and the brake member and in concert with the hub shell; thus, the coaster brake mechanism operates as a reverse driving mechanism.
    • 本发明的过山车制动器设置有一个与踏板驱动的驱动体螺旋配合的离合器锥体,以便与驱动体的转动方向相对应地可轴向运动,一个通过不能转动的离合器机构支承的制动锥体 并且允许其沿相反方向转动;以及制动构件,其被驱动以通过前述离合器锥体移动以接近上述制动锥体侧而在轮毂壳上施加制动,当驾驶体转向时 反方向。 当轮毂壳沿向前方向转动时,制动动作可以通过向驾驶体反转旋转同样地表现为常规的过山车制动器。 此外,上述制动锥体能够通过离合器机构沿相反的方向旋转,并且当驱动体经受反向转动时,当轮毂壳体不向前转动时,上述制动锥体将在 与驱动体,离合器锥体和制动部件一体地反向并与轮毂壳一致; 因此,过山车制动机构作为反向驱动机构动作。
