A brake disc arrangement to be located at an end of an axle of a vehicle driven by an electric motor includes a rotor assembly having multiple rotor assembly pieces joined together with fasteners, aswell as an adaptor. The pieces mentioned include rotor sections defining an engagement portion having surfaces to be contacted by friction pads. The rotor assembly also includes an attachment base andan intermediate section, surrounding a rotor assembly axis of rotation, extending along the rotor assembly axis of rotation between the engagement portion and the attachment base. When assembled, theadaptor extends between a wheel hub base and the attachment base of the rotor assembly so that the rotor assembly is securable to the wheel hub. The adaptor defines an internal volume within which ahousing for the electric motor and at least a portion of the wheel hub are receivable. 一种制动盘布置，其位于由电力马达驱动的车辆的轮轴的端部，包括具有利用紧固件连结在一起的多个转子组装件的转子组件，以及适配器。所提及的部件包括限定具有要与摩擦垫接触的表面的接合部的转子区段。转子组件还包括附接基部和中间区段，中间区段围绕转子组件的旋转轴线，沿着转子组件旋转轴线在接合部
