    摘要： A door opener with an anti-loose linking unit includes a driving device and a linking unit disposed between the driving device and the door. The driving device includes a motor and a first transmission member operatively connected to the motor. The linking unit includes a first push rod connected via a connecting screw to the first transmission member, permitting joint pivotal movement. An anti-loose member is non-rotatably mounted on the first push rod. Ahead of the connecting screw is non-rotatably coupled with the anti-loose member. Thus, the connecting screw cannot rotate relative to the first transmission member and the first push rod, reliably preventing the first push rod from disengaging from the first transmission member.

    摘要： A railroad hopper car body includes a set of hopper and hopper discharges. Egress of lading from the discharges is governed by movable doors that swing between a closed position and an open position. The motion is driven by a mechanical transmission that is itself driven by an actuator. Each pair of doors is driven by a single actuator. The actuator is mounted to act through the center sill. A portion, or substantially all, of the actuator may be mounted in a predominantly squat, vertical orientation within the center sill. In alternate embodiments, the transmission output may be bifurcated. The center sill bottom flange may be narrower adjacent to the doors. The mechanism may have a secondary lock. The mechanism may have an auxiliary manual release.

    摘要： The present invention provides a drive mechanism for a vehicle lift gate. The drive mechanism includes a housing including a first end securable to a vehicle frame and an opposite second end securable to a lift gate. The drive mechanism further includes a spring disposed for movement within the housing along the axis between the first and second ends and biasing the first end axially relative to the second end. A damper extends around the housing for absorbing energy released by rapid axial movement of the spring relative to the housing.

    摘要翻译： 本发明提供一种用于车辆升降门的驱动机构。 驱动机构包括壳体，该壳体包括可固定到车辆框架的第一端和可安装到升降门的相对的第二端。 驱动机构还包括弹簧，弹簧被设置成沿着轴线在第一和第二端之间在壳体内移动并且相对于第二端轴向偏置第一端。 阻尼器围绕壳体延伸以吸收通过弹簧相对于壳体的快速轴向运动释放的能量。
