Abstract: The present invention is for a multi-combination vehicle or road-train consisting of a powered prime mover, at least one powered trailer and which may include a number of non-powered trailers. The power trailer includes a cooling device separated from the engine to provide improved cooling and enabling the road-train to be used in confined areas such as in underground mines. Typically the cooling device located at the front or rear of the power trailer. The engines of the prime mover and power trailer(s) are controlled either by a synchronisation-system and a dual-pot accelerator pedal by controlling their relative torques or by manual controls in the truck cab.

Abstract: A torque distribution control device for a four-wheel drive vehicle is disclosed, wherein a torque transmitted from an engine to prime drive wheels is distributed by an electromagnetic clutch to sub-drive wheels on an on-demand basis. A pre-torque is determined based on a vehicle speed and a throttle opening degree in a feed-forward sense. A compensation torque is determined based on the rotational speed difference between the prime drive wheels and the sub-drive wheels and the vehicle speed in a feedback sense. The pre-torque and the compensation torque are added for a command torque, depending on which the electromagnetic clutch is controlled to transmit the torque from the engine to the sub-drive wheels.

Abstract: An articulated vehicle is made up of two independently moveable vehicle bodies, for instance tracked vehicle bodies. The first vehicle body has an engine and the second one has a motor/generator. An articulation device connects them to allow the first vehicle body to drive the second vehicle body or vice versa or even for them to act together. A drive transmission that can be used in the vehicle allows power to be input from two shafts or for one of the shafts to be an additional power output. An articulation device that can be used in the vehicle allows quick alignment and/or coupling and decoupling of the two bodies.

The upper arm assembly of the supporting unit is connected to the upper pivot arm assembly. The lower arm assembly of the supporting unit is connected to the lower pivot arm assembly. A compressible shock unit is provided to dampen movement of the system.

Abstract: A motorcycle support stand has a horizontally large base plate which stably engages a flat floor and mounts thereon a pair of sidewardly spaced uprights which define a gap therebetween for accommodating a motorcycle tire. The uprights have lower ends fixedly securable to the base plate, with at least one upright being slidably adjustable to vary the width of the gap. The upright has a leg part with a curvature similar to the rear tire so as to engage the side of the tire when the uprights are clamped together with the tire.

Abstract: A roller peg includes a housing, a roller, a pin, and a keeper. The pin affixes the roller inside the housing such that a surface of the roller protrudes from a hole in the side of the housing. The keeper holds the pin and roller in place within the housing. The roller spins within the housing when a surface of the roller contacts an exterior surface.

Abstract: A children's cycle comprising frames, wheels under the frames and a push-handle connected with the frames. The push-handle is arcuate in shape and movably connected with the frames. The push-handle may be turned down to the underside of the cycle body with its arcuate concave facing upward so that the cycle body is supported by the push-handle. The push-handle may be used for pushing or pulling the cycle, and may be turned down to the underside of the cycle body for rocking the cycle forward and backward.

Both crawler drive assemblies utilize identical mounting configurations for connecting the hydraulic drive motor to the frame of the crawler.

Abstract: Turning radius is calculated from steering angles of steering-wheels and articulation angles of respective frames, and the steering-wheels are automatically rotated faster than rear-wheels based on the turning radius, the revolution number of the rear-wheels, engine speed of an engine and a speed range of hydraulic motors, so that conventional trouble for manipulating operation lever etc. while turning a motor grader and skill-requiring work for adjusting the revolution number of the steering-wheels in accordance with the revolution number of the rear-wheels can be eliminated, thereby easily and accurately controlling the revolution number of the steering-wheels and securely preventing tight-corner braking phenomenon.

Abstract: A tow-bar having a skeletonized tongue portion is described. A stopper is typically includes on the bottom portion of the tongue. A head piece having handles internal to the head piece is connected to one end of the tongue. The handles are typically positioned in a triangular arrangement. The end of the tongue, opposite the end including the head piece, includes a hinging portion that can be connected to the respective cart having the tongue. The hinging portion and the head piece include “keyed” ends so that they can connect to the tongue like puzzle pieces. These keyed portions are welded to the tongue. In this way, the pull points are not straight welds but rather keyed and welded portions thereby able to withstand typical abuse.

Abstract: An apparatus facilitating the lifting and movement of objects. The present invention, in one embodiment, features a curved rim extending around a mounting plate to which an object or an object carrier can be attached. The object is mounted off-center relative to the central axis of the curved rim. According to the invention, a counter-balancing weight offsets the moment associated with the object to allow the moving device to roll along a surface, and thereby move the object, with application of a small amount of force. According to embodiments of the present invention, the curved rims include at least one section having an increased radius of curvature relative to other sections of the curved rim to promote rotation of the moving device.
