| 21 | Single laterally bendable track snowmobile | US859381 | 1986-05-05 | US4714125A | 1987-12-22 | Jack C. Stacy, Jr. |
| A vehicle especially adapted for traveling on snow, which has a single endless track made bendable laterally in order to change direction of travel. The vehicle has a main body assembly which is separated and supported above the track by a special suspension arm. A motor is located in the body assembly, and a drive train is connected between the motor and track. The drive train extends through the suspension arm. The steering control system also passes through the suspension arm and causes the track to flex laterally into a curve in a manner which positions the rider over the flotation centerline of the curved track and thereby maintains balance while negotiating turns. One end of the suspension arm is sprung from the track, and the body is sprung from the other end of the suspension arm. | ||||||

| An advancing support for providing a continuous propping, particularly for providing a continuous propping of mine galleries or like passageways, comprising at least two carriages for articulated tracks, each of said carriages including a beam having rounded ends and an articulated track closely surrounding the beam mounted for sliding friction on the beam, each of said beams being divided into spaced-apart longitudinal elements, a connecting element pivotally attached to each of said longitudinal elements for joining them together, said carriages being disposed one above the other to be applied respectively against the floor and roof of a gallery; at least one jack attached to the connecting element of the upper carriage and the connecting element of the lower carriage thereby joining said carriages together. | ||||||
| 23 | Endless track vehicle having a steerable end and method for operating the same | US652823 | 1976-01-27 | US4051914A | 1977-10-04 | Jorma Toivo Tapani Pohjola |
| An endless track vehicle one end at least of which is steerable, as well as a method for operating the same. Front and rear end roll structures guide an endless track vehicle for movement, and at least one of these structures can be angularly displaced with respect to the frame of the vehicle for the purpose of executing a turn during which one side of the track becomes shorter while the opposite side thereof becomes longer. In order to execute a turn, one of the end roll structures is angularly displaced about an upright axis in a substantially horizontal plane, and at the same time this one end roll structure is free to assume an angular position determined by the endless track which engages the latter end roll structure. A connecting structure is provided for connecting at least the one angularly displaceable end roll structure to the frame of the vehicle, this connecting structure providing for the angular displacement of the one end roll structure to execute a turn while at the same time providing for the end roll structure the capability of freely assuming an angular position determined by the endless track itself. | ||||||

| PURPOSE: To further reduce the size of a car body, including the longitudinal length by providing an induction member which is engaged with the inner surface of a caterpillar band and capable of bending right and left, interlocking with a steering handle. CONSTITUTION: An induction member 8 is plate-like as the whole and made by flexible resin such as resin or the like to be freely bent right and left. Both front and rear end portions are like a recessed circular arc corresponding to both sprockets 2, 3, an upper edge portion 8a and a lower edge portion 8b are formed on the longitudinal upper and lower parts, and a space portion where an engine or the like is inserted is formed in the middle portion sandwiched by both upper and lower edge portions 8a, 8b. The induction member 8 is constructed so that when a steering handle is operated right and left, a portion A is turned right and left with a front sprocket 2 to be curved in the longitudinal direction. At this time, a caterpillar band is also adapted to bend right and left, thereby operating a vehicle. COPYRIGHT: (C)1989,JPO&Japio | ||||||

| A serpentine robotic crawler includes an articulated body having at least two body segments serially connected and a continuous track operably supported along a perimeter of the articulated body. The serpentine robotic crawler is capable of a variety of movement modes and poses. | ||||||
| 33 | Dynamically steerable mono belt apparatus | US09800109 | 2001-03-06 | US06517457B2 | 2003-02-11 | Hagen Schempf; William A. Crowley; Robert A. Fuchs; Joshua N. Guyot; Edward C. Mutschler, Jr. |
| The present invention is a dynamically steerable mono belt apparatus and includes a first pivotable body element in communication with a second pivotable body element. A first pivot mechanism is attached to and positioned between the first pivotable body element and the second pivotable body element to allow the first pivotable body element to pivot in a first pivot plane of movement with respect to the second pivotable body element. The present invention also includes a continuous belt element formed as a loop and continuously rotatable in a first plane of rotation around the first pivotable body element, the first pivot mechanism and the second pivotable body element. The continuous belt element is flexible in the pivot plane of movement, such that when the first pivotable body element is pivoted, via the first pivot mechanism, in the pivot plane of movement, the continuous belt element is flexed. | ||||||
| 34 | Method and a support arrangement in a roller vehicle to be steered by a roller mat | US466422 | 1990-03-26 | US5009278A | 1991-04-23 | Timo Laakso |
| A method and a support arrangement to steer a roller vehicle by a roller mat, which vehicle has an essentially rigid body part supporting the frame and the power engine with transmission means thereof to transmit power to a curved form turnable roller mat, whereby one side of the roller mat is shortened and the other side thereof is correspondingly lengthened. According to the invention, when the roller mat is being turned to a curved form the vehicle is tilted and its center of gravity is transferred to the side of the tilt in regard to the longitudinal axis of the vehicle. The support arrangement extends essentially the whole length of the body part, is suspended to the body part and comprises a separate, twistable, i.e. bendable or foldable, auxiliary body part supported to the support arrangement at two points on the center line of the vehicle, to which body the roller wheel assembly of the roller mat has been suspended nontransferably in regard to the auxiliary body, and which body is provided with means connected to the steering devices of the vehicle to twist the auxiliary body and thus to steer the vehicle. | ||||||
| 35 | Mounting mechanism for endless traction band system | US202065 | 1980-10-30 | US4405026A | 1983-09-20 | Donald V. Merrifield |
| A mounting mechanism for an endless traction band system in which the endless band is supported on and driven by a pair of laterally spaced roller chains. The mounting mechanism supports a double sprocket for engaging the chains and is adapted to permit a limited degree of skewing by the sprocket wheel shaft so as to maintain the sprockets in alignment with the roller chains even when the roller chains are deformed in response to laterally imposed loads. | ||||||
| 36 | Steering mechanism for track vehicles | US438191 | 1974-01-31 | US3934664A | 1976-01-27 | Jorma Toivo Tapani Pohjola |
| A vehicle which has a pair of end rolls and an endless track guided around the end rolls is provided at its endless track with a central substantially non-stretchable region cooperating with the endless track structure to render the latter substantially rigid at the ends of the track which extend around the end rolls to prevent any slipping of the track with respect to the end rolls particularly when at least one of the end rolls is swung about an upright axis to enable the vehicle to execute a turn. On opposite sides of its central endless region the endless track has a pair of opposed lateral regions capable of automatically expanding and contracting when the vehicle executes turns so that the inside lateral region contracts while the outside lateral region expands during a turn, and the manner of contraction and expansion of these lateral regions of the endless track is such that together with a curving of the central non-stretchable region the endless track assumes a smooth uniform curve configuration when the vehicle executes turns. | ||||||
