Abstract: A semi-truck trailer gooseneck assembly comprises a single curved plate extending transversely between and beyond the twin parallel longitudinal girders to form a single lower flange. The curved plate extends from the assembly supporting the floor over the fifth wheel and connecting the king pin to the trailer. The rear portion of the curved plate extends to the horizontal flat lower flanges of the twin girders extending substantially the length of the trailer. The result is a structure of increased strength and moment of inertia permitting the web depth of the gooseneck to be substantially decreased.The rear corner post comprises a two piece welded assembly wherein the major section is substantially an elongated "S" and the minor section "L" shaped. The shapes are welded together to form a hollow center portion and a pocket portion. The "L" section forms a contact for the rear door and the pocket engages the curtain to enable the curtain to be fully tightened when closed. The configuration permits the post to retain sufficient column strength with an overall thickness of only one inch.

Abstract: Fluid circuit means to elevate the rear end of a truck trailer are incorporated in the air ride suspension means for the truck trailer and in communication with the air brake or spring brake fluid circuitry. The fluid circuitry provides manually controllable means to elevate the bed of the truck trailer at the rear thereof when the truck trailer is parked.The fluid circuitry is in communication with the spring brake fluid circuitry to prevent elevation of the truck trailer when the truck trailer parking brakes are not applied. The fluid circuitry provides a manually controllable connection bypassing the leveling valves to raise the truck trailer by admitting additional air under pressure into the air ride bags supporting the trailer. The fluid circuitry connections assure that the elevating system will be released and the excess air in the air ride bags exhausted automatically when the spring brake circuitry is pressurized to release the trailer parking brake. The connection with the spring brake circuitry is a safety feature in the event the operator does not release the manual control for the elevating means prior to releasing the parking brakes on the trailer.

Abstract translation: 用于提升卡车拖车的后端的流体回路装置被并入用于卡车拖车的空气悬挂装置中，并与空气制动器或弹簧制动器流体回路连通。 流体回路提供手动可控的装置，以在卡车拖车停放时在其后部提升卡车拖车的床。 流体回路与弹簧制动器流体回路连通，以防止在卡车拖车停车制动器不被施加时卡车拖车升高。 流体回路提供一个手动可控制的连接，绕过调平阀，以通过承受额外的空气在压力下升至支架拖车的空气行李袋中来提升卡车拖车。 流体回路连接确保升降系统将被释放，并且当弹簧制动器电路被加压以释放拖车驻车制动器时，空气行李箱中的多余空气自动排出。 与弹簧制动电路的连接是安全功能，在操作员在释放拖车上的驻车制动器之前不释放升降装置的手动控制。

Abstract: The invention comprises an improved movable truck bumper that can be raised and lowered vertically from inside the cab of the truck to which the bumper is attached. The bumper includes an electrical control inside the cab to raise and lower the bumper and to signal the bumper height to the operator. The operator can thereby ascertain the height of the bumper without exiting the cab or viewing the bumper with mirrors. In the preferred embodiment, lights identifying the correct bumper heights for various automobile models or body styles are mounted in a control box with the height control adjacent the operator.The mechanical portion of the bumper comprises a vertical support frame attached to the vehicle frame in place of the standard bumper and a vertically movable lift frame nested onto the support frame. A vertically mounted hydraulic cylinder is substantially nested within the support and lift frames providing an exceptionally compact structure that can be mounted very close to the front of the vehicle.

Abstract translation: 本发明包括一种改进的可移动的卡车保险杠，其可以从卡车的驾驶室的内部垂直升高和降低，保险杠附接到该保险杠。 保险杠包括驾驶室内的电气控制器，用于升高和降低保险杠，并向操作员发出保险杠高度。 因此，操作者可以确定保险杠的高度，而不会离开驾驶室或用镜子观看保险杠。 在优选实施例中，识别用于各种汽车模型或车身风格的正确保险杠高度的灯被安装在具有与操作者相邻的高度控制的控制箱中。 保险杠的机械部分包括连接到车架的垂直支撑框架，代替标准保险杠和嵌套在支撑框架上的垂直移动的提升架。 垂直安装的液压缸基本上嵌套在支撑件和提升框架内，提供非常紧凑的结构，其可以非常靠近车辆前部安装。
