    • An electrically actuated hydraulic power cylinder (10, 100, 200) for use in a vehicle braking system. The power cylinder includes an electric motor (12, 102, 202), a rotary-to-linear actuator for converting rotary motion of the electric motor to a linear motion, and a hydraulic cylinder. In a preferred embodiment, the rotary-to-linear actuator is a roller screw assembly (14, 104, 204). The roller screw assembly converts rotational motion generated by the motor into axial movement of a piston which is disposed within the hydraulic cylinder. The movement of the piston pressurizes a volume of fluid. The pressurized fluid flows through an outlet port (20) connected to either a single wheel brake cylinder (21) or a plurality of wheel brake cylinders, thereby actuating the associated wheel cylinder. In a specific embodiment of the invention, the roller screw assembly is incorporated into the internal structure of the motor for compactness and weight reduction. Also, the hydraulic cylinder may be integrated into a wheel brake assembly for compactness and weight reduction.
    • 一种用于车辆制动系统的电动液压动力缸(10,100,200)。 动力缸包括电动机(12,102,202),用于将电动机的旋转运动转换为直线运动的旋转线性致动器和液压缸。 在优选实施例中,旋转到线性致动器是滚子丝杠组件(14,104,204)。 滚子丝杠组件将由马达产生的旋转运动转换成设置在液压缸内的活塞的轴向运动。 活塞的运动加压一定体积的流体。 加压流体流过连接到单轮制动缸(21)或多个车轮制动缸的出口(20),从而致动相关的轮缸。 在本发明的一个具体实施例中,滚子丝杠组件被结合到马达的内部结构中,用于紧凑和重量减轻。 此外,液压缸可以集成到车轮制动组件中,用于紧凑和重量减轻。

    • An improved structure for an electro-mechanical disc brake caliper assembly. The electro-mechanical disc brake caliper assembly includes an electro-mechanical actuation mechanism, a piston unit, and a freewheeling clutch. The electro-mechanical actuation mechanism includes an electrical actuating unit, an eccentric actuating lever, a mechanically actuated piston unit, and an automatic adjustment mechanism. The electrical actuating unit includes an electric motor and a motor spindle operatively coupled to the motor so as to convert rotary motion of the motor into axial movement of the motor spindle. The motor spindle operatively engages the lever so as to cause the lever to pivot relative to a lever pivot axis. The piston unit is operatively coupled to the lever and includes a piston spindle and a piston. The piston spindle is operatively coupled to the lever so as to be axially moved during actuation of the lever. The piston spindle is operatively coupled to the automatic adjustment mechanism so as to cause adjustment of the piston spindle during actuation of the electro-mechanical actuation mechanism if the piston moves more than a predetermined brake clearance distance. The freewheeling clutch is adapted to limit the adjustment provided by the automatic adjustment mechanism.
    • 机电盘式制动钳组件的改进结构。 机电盘式制动钳组件包括机电致动机构,活塞单元和续流离合器。 机电致动机构包括电驱动单元,偏心致动杆,机械致动的活塞单元和自动调节机构。 电动执行单元包括电动马达和可操作地联接到马达的马达轴,以将马达的旋转运动转换成马达主轴的轴向运动。 马达主轴可操作地接合杠杆,以便使杠杆相对于杠杆枢转轴线枢转。 活塞单元可操作地联接到杠杆并且包括活塞主轴和活塞。 活塞主轴可操作地联接到杠杆,以便在杠杆的致动期间轴向移动。 活塞主轴可操作地联接到自动调节机构,以便如果活塞移动超过预定的制动间隙距离,则在机电致动机构的致动期间调节活塞主轴。 续流离合器适用于限制由自动调节机构提供的调节。
