摘要： A driving form switching apparatus enabling even a user of wheelchair who cannot freely use limb to easily change over a driving form by single hand self-operation. By using a differential gear mechanism or a combination mechanism comprising pinions and racks, the rotating, tilting and shifting motions of a steering lever are transmitted to two rotating shafts. Drums are directly coupled to the two rotating shafts, and the rotations of the two rotating shafts are transmitted to steering shafts through flexible wires as first connecting means. Also, the steering shafts for wheels are parallel- or cross-connected by second connecting means. Thus, the driving forms of a four-wheel drive vehicle such as back and forth traveling, counter-clockwise turning, clockwise turning, turning on the spot, parallel traveling, stopping and braking, etc, can be switched by a single-hand simple operation.

摘要： A motor driven vehicle for traversing the interior of a pipe or conduit accommodates itself to variations in the interior contour of the pipe and automatically positions itself on the longest axis of any cross section of the pipe. It comprises a pair of two-wheeled trucks each pivotally connected to an end of a stretcher member which urges the trucks away from each other against diametrically opposite paths of travel on the pipe wall. Each truck has a driving wheel and a swivelling wheel, the driving wheels being diagonally opposite each other. The driving wheel motors are servo-connected so as to keep the angles between stretcher and truck bolsters equal. The driving wheels are preferably constructed with rim segments which rotate about axes tangent to the mean circumference of the rim, thereby permitting movement sidewise of the wheel.
摘要翻译：用于横穿管道或导管内部的电机驱动车辆可容纳其内部轮廓的变化，并自动将其自身定位在管道的任何横截面的最长轴线上。它包括一对两轮卡车，它们各自枢转地连接到担架构件的端部，该牵引构件推动卡车彼此远离管道壁上径向相对的行进路线。每辆卡车都有一个驱动轮和一个旋转轮，驱动轮彼此对角相对。驱动轮电动机是伺服连接的，以保持担架和卡车支架之间的角度相等。驱动轮优选地构造有围绕与轮辋的平均圆周相切的轴线的边缘段，从而允许轮的侧面移动。

摘要： A motor driven vehicle for traversing the interior of a pipe or conduit comprises a pair of arms pivoted to each other at one pair of ends, a drive wheel the axle of which may coincide with the pivot, a swiveling wheel carried at the other end of each arm and a spring positioned to pull the arms toward each other so that the dimension of the vehicle across a pipe is automatically maximized. The vehicle thus tends to position itself on the longest axis of any cross section of the pipe. The drive wheel may be constructed with rim segments which rotate about axes tangent to the means circumference of the rim.
