    • In order to prevent serious damage to a flight control system in a failure mode, a failure protection unit includes an input shaft connected to a shaft of the flight control system with the input shaft normally being operably associated with a plunger having a brake hub integral therewith for rotational driven movement of the plunger and the brake hub through the input shaft. The plunger and the brake hub are movable relative to the input shaft, and a brake reaction plate is positioned within a housing in normally spaced relation to the brake hub. The brake hub is biased by a spring in a direction toward the brake reaction plate and the plunger is biased by the spring in a direction away from the input shaft. The plunger is normally locked against movement by a detent which resists movement of the plunger away from the input shaft and movement of the brake hub toward the brake reaction plate. With these features of construction, a trip mechanism initiates engagement of the brake hub with the brake reaction plate responsive to an overspeed condition for the shaft of the flight control system by disabling the detent to thereby allow the spring to cause movement of the brake hub toward the brake reaction plate and movement of the plunger away from the input shaft.
    • 为了防止在故障模式下严重损坏飞行控制系统,故障保护单元包括连接到飞行控制系统的轴的输入轴,输入轴通常与具有与其一体的制动轮毂的活塞可操作地联接 用于柱塞和制动轮毂通过输入轴的旋转驱动运动。 柱塞和制动轮毂可相对于输入轴移动,并且制动反作用板以与制动轮毂正常间隔的关系定位在壳体内。 制动轮毂由朝向制动反作用板的方向的弹簧偏压,柱塞被弹簧沿远离输入轴的方向偏置。 柱塞通常被止动器锁定以防止柱塞从输入轴移动并且制动轮毂朝向制动反作用板的运动。 利用这些结构特征,跳闸机构响应于飞行控制系统的轴的超速状态而启动制动轮毂与制动反作用板的接合,通过禁止制动器从而允许弹簧使制动轮毂朝向 制动反作用板和柱塞远离输入轴的运动。

    • An improved support ring (50) is disclosed for supporting a plurality of planetary gear sets (20) which are driven by a centrally disposed input shaft (12) having a sun gear (16) attached thereto in which the planetary gear sets are subject to radially inward loads. The support ring (50) includes an inner ring (52) and an outer ring (57). The inner ring (52) has a bore (54) which is disposed around the input shaft (12) and an outside surface (56) and the outer ring (57) has a bore (58) with a diameter greater than the diameter of the outside surface of the inner ring. The outside surface (60) of the outer ring rotatably supports the planetary gear sets (20). Preferably, the outer ring (57) has a spring rate which is less than the inner ring (52) to readily permit absorption of radial loads when the outer ring does not contact the inner ring. A retaining ring (62) may be provided to maintain a fixed axial relationship between the inner (52) and outer rings (57).

    • A vehicle transmission having power shift means and an overrunning clutch to selectively provide a multiple speed transmission with shifting of the vehicle transmission while the vehicle is operating. The transmission includes a main drive shaft, a jackshaft and a countershaft with a selective manual gear shift on the countershaft. The main drive is through the countershaft and a plurality of gearsets having clutching means to manually select one of a plurality of speed ratios. The first input speed drives through the first overrunning clutch to the main drive shaft. The jackshaft is selectively engaged through a power shift clutch to provide a second input speed to the main drive shaft. When the jackshaft is in operation, the first overrunning clutch is disengaged and the drive is through the power shift clutch to rotate the main drive shaft at the higher speed. This provides two input speeds to the main drive shaft which are controlled by the operator by selectively engaging or disengaging of the power shift clutch. The second overrunning clutch is connected between the input shaft and the jackshaft and normally is disengaged when the jackshaft is in operation. The second overrunning clutch, however, provides the advantage of having a means for braking the vehicle through the engine when the vehicle is coasting and power shift clutch is disengaged, since the second overrunning clutch is then engaged and counterrotates to provide the braking means.
    • 一种具有动力换档装置和超速离合器的车辆变速器,其在车辆运行时选择性地提供具有车辆变速器的变速的多速变速器。 变速器包括主驱动轴,千斤顶轴和中间轴,在中间轴上具有选择性的手动换挡。 主驱动装置是通过中间轴和具有手动选择多个速比之一的离合装置的多个齿轮组。 第一输入速度通过第一超越离合器驱动到主驱动轴。 千斤顶选择性地通过动力换档离合器接合以向主驱动轴提供第二输入速度。 当千斤顶运行时,第一超越离合器分离并且驱动器通过动力换挡离合器以使主驱动轴以较高的速度旋转。 这通过选择性地接合或分离动力换档离合器来为操作者控制的主驱动轴提供两个输入速度。 第二超越离合器连接在输入轴和千斤顶轴之间,并且当千斤顶运行时通常断开。 然而,第二超越离合器提供了当车辆滑行并且动力换档离合器分离时具有用于通过发动机制动车辆的装置的优点,因为第二超越离合器然后被接合并逆转以提供制动装置。

    • A backdrive overload clutch mechanism which includes a rotatable drive member and a rotatable driven member mounted concentric with respect to the drive member. A pair of cooperating clutch jaws, including chamfered teeth, are provided with one jaw on each of the drive and driven members for rotation therewith and separable by relative movement between the members longitudinally of their axis of rotation. A first spring normally urges the clutch jaws into driving engagement. A tongue-and-groove disengaging device disengages the clutch jaws automatically in response to relative rotation between the clutch jaws. A second spring maintains the clutch jaws out of driving engagement when the clutch jaws are automatically disengaged.

    • An automatic neutral position locking system for a control surface of an aircraft. A hydraulic prime mover is provided for moving the control surface. A locking device is capable of locking the control surface against movement. A ratchet-and-pawl device is operatively associated with a rotary drive train between the prime mover and the control surface for actuating the locking device in response to the control surface reaching a neutral position. The ratchet-and-pawl device normally is maintained in inactive condition when hydraulic pressure exists in the prime mover. A pneumatic piston-and-cylinder device, when under pressure, maintains the ratchet-and-pawl device in normally inactive condition. With a loss of hydraulic pressure, the ratchet-and-pawl device is effective to actuate the locking device in response to the control surface itself reaching the neutral position as the control surface moves under external loads.
