摘要： A collapsible tow bar assembly adapted to extend between a towing vehicle and a towed vehicle. A frame is provided which includes a bearing element secured to the front end of the frame and a mounting element secured to the rear end of the frame. The mounting element is adapted to be selectively connected to the receiver hitch of a towing vehicle, while the bearing element extends rearward toward the towed vehicle. A pair of elongated, telescopic swing arms are pivotally secured to the bearing element and extend to the towed vehicle for attachment thereto. The bearing element further includes a yoke rotatable about a ball joint having at least two degrees of freedom which allows for movement of the swing arms in both vertical and horizontal planes. The swing arms further include pivot flanges that are pivotally secured to the swing arms at an end nearest the towed vehicle. A pair of tow vehicle mounting brackets extend from the frame of the towed vehicle vertically upward, such that when not in use, the tow bar assembly may be collapsed and securely stored adjacent the rear bumper of the towing vehicle.

摘要： A tow bar assembly adapted to extend between a towing vehicle and a towed vehicle. A frame is provided which includes a bearing element secured to the front end of the frame and a mounting element secured to the rear end of the frame. The mounting element is adapted to be selectively connected to the receiver hitch of a towing vehicle, while the bearing element extends rearward toward the towed vehicle in one embodiment. A pair of elongated, telescopic swing arms are pivotally secured to the bearing element and extend to the towed vehicle for attachment thereto. The bearing element further includes a yoke rotatable about a ball joint having at least two degrees of freedom which allows for movement of the swing arms in both vertical and horizontal planes. The swing arms further include pivot flanges that are pivotally secured to the swing arms at an end nearest the towed vehicle. A pair of tow vehicle mounting brackets extend from the frame of the towed vehicle vertically upward, such that when not in use, the tow bar assembly may be collapsed and securely stored adjacent the rear bumper of the towing vehicle. Alternate embodiments include fifth wheel and fixed arm tow bar assemblies.
摘要翻译： 牵引杆组件，其适于在牵引车辆和牵引车辆之间延伸。 提供一种框架，其包括固定到框架的前端的轴承元件和固定到框架的后端的安装元件。 在一个实施例中，安装元件适于选择性地连接到牵引车辆的接收器搭接部，同时轴承元件向后朝向被牵引车辆延伸。 一对细长的可伸缩摆臂枢转地固定到轴承元件并延伸到牵引车辆以附接到其上。 轴承元件还包括可围绕具有至少两个自由度的球形接头旋转的轭，其允许摆臂在垂直和水平面中的移动。 摆臂还包括枢转凸缘，其枢转地固定到最靠近被牵引车辆的一端的摆臂。 一对拖车车辆安装支架从拖曳车辆的车架垂直向上延伸，使得当不使用时，拖曳杆组件可以在牵引车辆的后保险杠附近收缩并牢固地存放。 替代实施例包括第五轮和固定臂拖杆组件。
