摘要： A landing gear for semitrailers includes a two-speed single reduction gear assembly having fewer, smaller, and simpler parts, resulting in a compact single reduction gear assembly and cost efficient landing gear unit with a unique clutch-shifting mechanism to provide for shifting from one ratio to another. The single reduction gear assembly is disposed on and about vertically offset input and output shafts further resulting in an easy to crank and shift landing gear unit capable of achieving standard crank handle turn to vertical leg travel distance ratios. The low gear or low speed ratio of the landing gear unit can be varied within a broad range during manufacture, if desired, generally without increasing the overall size or complexity of the two-speed single reduction gear assembly. The landing gear can further include a universal mounting feature and is durable and simple to use.
摘要翻译：用于半挂车的起落架包括具有更少，更小和更简单的部件的双速单速减速齿轮组件，导致紧凑的单个减速齿轮组件和具有成本效益的起落架单元，其具有独特的离合器转换机构以提供从一个比例到另一个。单个减速齿轮组件设置在垂直偏移的输入和输出轴上并且围绕垂直偏移的输入和输出轴，进一步导致容易的起落架起落架单元能够实现标准的曲柄手柄转到垂直的行程距离比。如果需要，起落架单元的低速或低速比可以在制造期间在宽范围内变化，通常不增加双速单级减速齿轮组件的总体尺寸或复杂性。起落架还可包括通用安装特征，并且耐用且易于使用。

摘要： The jack comprises a tubular primary screw (10) provided with an outer screw thread and an inner screw thread having opposite thread hands, a secondary screw (11) cooperative with the inner screw thread and having an end (11a) articulated to a fixed point, a nut (9) fixed in rotation and connected to move in translation with the element to be adjusted and cooperative with the outer screw thread, a speed reducer associated with a motor (M) for driving the primary screw (10) in rotation, and means for preventing a rotation of the speed reducer (13) relative to the nut (9). These means comprise an articulated compass structure (18) having two branches (18a, 18b) articulated together. One of the branches is also articulated to the speed reducer (13) while the other branch is articulated to a part (9) of the jack which is fixed in rotation. The compass structure (18) considerably reduces the friction and improves the efficiency of the jack.

摘要： A control system for a surveillance vehicle (V) is disclosed. The vehicle includes a rapid deployment and retraction mechanism (A') and a jack system (B') for continuously maintaining a detection device (28) a top a mast (12) within a prescribed vertical condition when extended. The control system includes a jack leveling logic circuit (C), a jack pressure control circuit (D), a ram control circuit (E), and a mast control circuit (F). Ram control circuit (E) controls a ram (52, 54, 56) which deploys and retracts mast (12). Jack pressure control circuit (D) senses the pressure on jacks (142a, 142b, 142d) at the four corners of the vehicle. Jack leveling logic circuit (C) receives pressure signals representing the pressure on the jacks and controls extension and retraction of the jacks in pairs at diagonal corners to maintain the vehicle within prescribed leveling conditions and to prevent the over extension or over adjustment under certain unleveling conditions. Mast control circuit (F) receives a signal representing the level condition of the vehicle so that the mast is extended and retracted only under prescribed leveling conditions.

摘要： A vehicle lifting jack assembly having a pantographic mechanism carrying a head bracket for engagement with a jack point formed in a vehicle body. The head bracket is formed with a first groove extending in one direction for accommodating a downwardly projecting flange portion of the vehicle body so that the head bracket can be engaged with a lower surface portion of the vehicle body at the opposite sides of the flange portion. The head bracket is further formed with a second groove which extends perpendicularly to the first groove for engagement with a support bracket provided in the vehicle body for storing the jack assembly in the vehicle body.

摘要： A motor home support for preventing horizontal and vertical sway of a motor home. A vertical mounting plate has a fixed horizontal arm secured thereto. A rotatable screw whose axis extends parallel to the axis of the horizontal arm is secured adjacent to the horizontal arm and has a movable nut positioned thereon. A planar ground support plate is movable from adjacent one end of the arm to a position wherein the ground support plate is in a plane generally parallel to the plane of the horizontal arm. A pivot junction is fixed to one side of the ground support plate. A first support leg interconnects the mounting plate and the ground support plate. A second support leg is interconnected at one end to the ground support plate and the other end to the movable nut.

摘要： A stabilizing jack for mounting beneath a recreational vehicle such as a trailer or self-contained motorized unit, the jack having a pair of legs pivotably mounted beneath the vehicle and extending in opposite directions from each other when retained in a normal horizontal position. The legs are moved downwardly into a stabilizing position beneath the vehicle with an equal force on both of the legs so that both of the legs strike the ground before further force is applied to either leg as, for example, when the vehicle is stabilized on uneven terrain. The upper parts of the legs are mounted for sliding movement within a housing and a cylinder connected to the upper portions and movably mounted therebetween forces the leg upper portions apart so that the lower portions of the legs extend downwardly to the ground. The jack can be used to raise the vehicle off its suspension as well as stabilize the vehicle.
摘要翻译：一种用于安装在诸如拖车或独立的机动化单元的休闲车辆下方的稳定插座，所述插座具有可枢转地安装在车辆下方并且当保持在正常水平位置时彼此相反方向延伸的一对支腿。腿部向下移动到车辆下方的稳定位置，相等的力在两条腿上，使得两个腿在向另一个腿施加进一步的力之前撞击地面，例如当车辆稳定在不平衡时地形。腿的上部安装成在壳体内滑动运动，并且连接到上部并且可移动地安装在其上的气缸迫使腿部上部分开，使得腿的下部向下延伸到地面。千斤顶可用于将车辆从悬架上升起并使车辆稳定。
