The invention relates to a reverse brake bearing assembly which comprises a hub barrel used for being connected with spokes. The rotary base cylinder is arranged in the hub cylinder, and the rotary base cylinder can only be in sliding connection with the hub cylinder in a reciprocating motion mode in the axis direction of the hub cylinder; the flywheel seat is used for mounting a flywheel, the flywheel seat is rotatably connected with one side of the hub cylinder, an external thread is arranged on one side, close to the rotating base cylinder, of the flywheel seat, an internal thread matched with the external thread is arranged on the inner wall of the rotating base cylinder, and the rotating base cylinder is in threaded connection with the flywheel seat; the brake assembly is used for being fixedly connected with a bicycle frame, the brake assembly is arranged on the side, away from the flywheel base, of the rotating base cylinder and rotationally connected with the hub cylinder in a lockable mode, when the rotating base cylinder is close to the brake assembly, the brake assembly and the hub cylinder enter a relative locking state, and when the rotating base cylinder is away from the brake assembly, the brake assembly and the hub cylinder are in a relative locking state. The brake assembly and the hub cylinder can rotate relatively. The braking device has the effect of controlling the force of reverse braking.

    本申请涉及一种倒刹轴承总成,其包括花鼓筒,花鼓筒用于连接辐条;旋转基筒,旋转基筒设于花鼓筒内,旋转基筒仅能够沿花鼓筒的轴线方向往复移动地与花鼓筒滑动连接;飞轮座,飞轮座用于安装飞轮,飞轮座与花鼓筒的一侧转动连接,飞轮座靠近旋转基筒的一侧设有外螺纹,旋转基筒的内壁设有与外螺纹相配合的内螺纹,旋转基筒与飞轮座螺纹连接;刹车组件,刹车组件用于与车架固定连接,刹车组件设于旋转基筒远离飞轮座的一侧且可锁止地与花鼓筒转动连接,当旋转基筒靠近刹车组件时,刹车组件与花鼓筒进入相对锁止状态,当旋转基筒远离刹车组件时,刹车组件与花鼓筒能够相对转动。本申请具有控制倒刹刹车的力度的效果。
