摘要： A vehicle with its own traveling gear for towing an aircraft without draw tongue, has a U-shaped chassis frame recess that is open in the forward direction with a clamping and lifting device arranged therein for the nose wheels of an aircraft. The clamping and lifting device, which is oscillatingly suspended on the chassis frame 1, includes a pivoting and lifting ramp 8, as well as two parallel telescoping arms 10 arranged rigidly on the pivoting and lifting ramp 8, with telescoping cylinders 11 and with gripping arms 14, which can be pivoted in and whose nose wheel contact surfaces 18 are rigidly attached to the gripping arms 14, and of telescopingly adjustable holddown devices 12, 13, which are hinged to the support 7.FIG. 3 shows the clamping and lifting devices with the nose wheels 17 lifted.

摘要： The aircraft tractor arrangement maintains a uniform degree of reliability with which the nose wheel landing gear, which is standing on a lifting platform that is arranged on the front part and extends into a recess (26), is held down on the surface of the lifting platform which supports the nose wheel landing gear at different nose wheel diameters.Each telescoping rod (30) is hinged (40, 44, 46) to the front part (10.1) directly in the front. A connecting hydraulic cylinder (42) is provided in the rear. The hydraulic cylinder (46) for longitudinal adjustment, and also the hydraulic cylinder (36) for moving the holder (34) on the fixed part (30.1) of the telescoping rod (30) associated with it are arranged ridgedly.This arrangement allows an adjustability in height of the two rear tow arms and at the same time of the front holders, which can come into contact with the two desired zones of the wheel circumference, regardless of the nose wheel diameter. The distance between the arms and the holders is adjustable.
摘要翻译：飞机拖拉机布置保持了一致的可靠性，其中站在提升平台上的前轮起落架布置在前部并延伸到凹部（26）中，并被提升到提升的表面上平台，支撑不同前轮直径的前轮起落架。每个伸缩杆（30）直接在前部铰接（40,44,46）到前部（10.1）。连接液压缸（42）设置在后部。用于纵向调节的液压缸（46）以及用于使与其相关联的伸缩杆（30）的固定部分（30.1）上的保持器（34）移动的液压缸（36）被脊向地布置。这种布置允许两个后拖曳臂的高度可调节，并且与前保持器的同时可以与轮周的两个期望的区域接触，而与前轮直径无关。臂和支架之间的距离是可调节的。

摘要： The present invention pertains to an aircraft tractor without tow-bar. The arrangement avoids relative movement between the nose wheel of the aircraft and the tractor lifting platform by making the lifting platform (24) rotatable around a longitudinal axis (30) of the chassis, which axis is horizontal when the chassis is extended, and by making displaceable the transverse tow arms (38) and/or the holders (42) at right angles to this longitudinal axis (30). The tires of an oblique nose wheel landing gear of an aircraft being towed in a curve are handled very gently, because the tractor parts (24, 38, and 42) that are in contact with the nose wheel landing gear are able to follow the movements of the nose wheel landing gear and to adjust to its instantaneous position.
摘要翻译：本发明涉及没有拖杆的飞机拖拉机。该布置通过使提升平台（24）能够围绕底盘的纵向轴线（30）旋转，从而避免了飞机前轮与拖拉机升降平台之间的相对运动，该底盘延伸时该轴线是水平的，并且通过制造横向牵引臂（38）和/或保持器（42）与该纵向轴线（30）成直角地位移。由于与前轮起落架接触的拖拉机部件（24,38和42）能够跟随运动，所以飞机拖着曲线的倾斜前轮起落架的轮胎被非常轻轻地处理的前轮起落架并调整到其瞬时位置。
