A braking assembly for inhibiting rotation of a wheel around a rotation axis is provided. The braking assembly includes a drive gear, an actuator, an electric braking assembly, a mechanical braking assembly including a brake pad, and a brake rotor fixedly coupled to the wheel. The drive gear rotates with the wheel and includes a pinion. The electric braking assembly includes a coil surrounding the rotation axis, and a magnetic disc assembly concentric with the coil and configured to rotate relative to the coil. The magnetic disc assembly includes a plurality of magnets at a perimeter of the disc. The actuator engages the pinion to inhibit rotation of the magnets and generate an electro motive force to inhibit rotation of the wheel. The actuator engages the brake pad to contact the rotor and inhibit rotation between the wheel and the brake pad.
提供了一种用于抑制车轮围绕旋转轴线旋转的制动组件。该制动组件包括驱动齿轮、致动器、电制动组件、包括制动衬块的机械制动组件和固定地联接到车轮的制动转子。驱动齿轮随车轮旋转并且包括小齿轮。电制动组件包括围绕旋转轴线的线圈,以及与线圈同心并且构造成相对于线圈旋转的磁性盘组件。磁性盘组件包括位于盘周边的多个磁体。致动器接合小齿轮以抑制磁体的旋转并且产生电动力以抑制车轮的旋转。致动器接合制动衬块以接触转子并抑制车轮与制动衬块之间的旋转。
