    • An apparatus, a system and a method have a speed-limiting braking mechanism. The apparatus may use a leash to limit a velocity of movement of a pet relative to a velocity of movement of a user of the apparatus. The speed-limiting braking mechanism within the apparatus may prevent the relative velocity from exceeding a predetermined threshold without abruptly stopping unwinding of the leash. The speed-limiting braking mechanism may have a rotatable pinion component connected to one or more brake shoes. The leash may be connected to a spool. Unwinding of the leash may rotate the spool, and rotation of the spool may rotate the pinion component. If the relative velocity exceeds the predetermined threshold, the one or more brake shoes may engage a braking liner to maintain the relative velocity at the predetermined threshold.
    • 装置,系统和方法具有限速制动机构。 装置可以使用皮带来限制宠物相对于装置的使用者的移动速度的移动速度。 装置内的限速制动机构可以防止相对速度超过预定阈值,而不会突然停止皮带的退绕。 限速制动机构可以具有连接到一个或多个制动蹄的可旋转小齿轮部件。 皮带可能连接到线轴。 皮带的松开可旋转卷轴,并且卷轴的旋转可以使小齿轮部件旋转。 如果相对速度超过预定阈值,则一个或多个制动蹄可接合制动衬套以将相对速度保持在预定阈值。
