摘要： A drawbar trailer for transporting very long, very heavy, substantially rigid loads, the trailer having a load support platform carried by at least one front and at least one rear axle and separable wheel assembly, the trailer comprising: an adjustable suspension system having inflatable members disposed between the platform and the front and rear axles for selectively raising and lowering the front and rear of the platform and for selectively raising and lowering the sides of the platform; the drawbar being pivotably mounted to the platform about a substantially vertical axis; a mechanism, preferably hydraulic, for turning the wheels of at least one of the front and rear axle and wheel assemblies; an automatic control system for activating the turning mechanism in response to pivotal movements of the drawbar; and, members for securing the load to the platform, whereby the tilt axes of the load support platform can be adjusted with respect to the axle and wheel assemblies, and in turn, with respect to terrain features. In the presently preferred embodiment, the drawbar trailer is particularly adapted for transporting rapid transit subway cars, railcars and like vehicles having internal suspension systems. Such a specially adapted drawbar trailer further comprises support members for holding and immobilizing the bodies of the carried vehicles with respect to the platform, preventing movement of the vehicle bodies on their internal suspension systems. The load support platform may be inclined about its tilt axes to facilitate loading, carrying and unloading the carried vehicle.
摘要翻译：一种牵引车拖车，用于运输非常长而非常重的，基本上刚性的载荷，所述拖车具有由至少一个前部和至少一个后桥和可分离轮组件承载的负载支撑平台，所述拖车包括：可调节的悬挂系统，其具有可充气构件设置在平台与前轴和后轴之间，用于选择性地升高和降低平台的前后，并且用于选择性地升高和降低平台的侧面; 所述牵引杆围绕基本垂直的轴线可枢转地安装到所述平台; 用于转动前轴和后轴与车轮组件中的至少一个的车轮的优选液压的机构; 用于响应于牵引杆的枢转运动来启动转动机构的自动控制系统; 以及用于将负载固定到平台的构件，由此可以相对于车轴和车轮组件而调节负载支撑平台的倾斜轴线，并且还可以相对于地形特征来调节负载支撑平台的倾斜轴。在目前优选的实施例中，牵引车拖车特别适于运输具有内部悬挂系统的快速过境地铁车厢，轨道车辆等。这种特别适应的牵引车拖车还包括用于相对于平台保持和固定携带车辆的车身的支撑构件，防止车体在其内部悬架系统上的运动。负载支撑平台可以围绕其倾斜轴线倾斜，以便于装载，携带和卸载所携带的车辆。
