20120187751LUBRICATING OIL MONITORING AND MAINTENANCE CAPS FOR ROLLERS OF A TRACKED VEHICLE - A roller of a tracked vehicle includes a lubricating oil reservoir having an open end closed by a sealing body having an outer face and an opposed inner face facing the reservoir, and which is transparent to provide visual access into the reservoir through the open end for lubricating oil level and quality monitoring purposes. A depression with a raised rim is formed in the outer face of the sealing body, and a port is formed in the sealing body, which extends through the sealing body at the depression from the outer face to the inner face of the sealing body. A removable plug is applied to and closes the port, and is positioned in the depression and extends outwardly from the outer face of the sealing body no further than the raised rim isolating the plug from shearing forces across the outer face of the sealing body.07-26-2012
20100007205Self-lubricated track roller assembly and machine using same - A track roller assembly for a track-type machine such as an excavator or a tractor includes an outer surface with no fluid ports and an inner surface free from any fluids. The track roller includes self-lubricated bushings, which include a substrate that has lubricating properties, such as a substrate that carries a solid lubricant, which allows the track roller to require no liquid lubrication requiring regular maintenance. The bushing is sealed to prevent debris from entering a clearance between the bushing and the shaft as well as preventing any of the bushing's solid lubricant from escaping.01-14-2010
20080290728Bi-directional ice-particle spray generating device for snow vehicles - A bi-directional ice-particle spray generating device for use on snow vehicles is disclosed which is primarily constructed of multi-strand wire rope. The use of wire rope as a spring member allows for 360 degree flexibility to enable the design to be compatible with reverse-gear-equipped snow vehicles. A replaceable wear point or points is integral in the design for added durability.11-27-2008
305116000 TRACK GUIDE OR ALIGNMENT MECHANISM 3
20090278403Track unit for moving a ground work vehicle - A track unit for moving a ground work vehicle, comprising two elastic elements proximate to the front and rear ends, interposed between a monolithic upper portion of the structure that supports the driving wheel and a monolithic lower portion that supports two pairs of coaxial guiding wheels with parallel axles and resting rollers, means adapted to ensure a coplanar arrangement of the upper and lower portions of the structure being also provided.11-12-2009
20090212623Adaptable traction system of a vehicle - A traction system for a vehicle has a support frame that defines a circular track belt support that is revolvable about an axis at its center, a flexible track belt; and a track belt stretching assembly comprising one or more track belt stretching rollers. The system has one traction configuration in which the flexible traction belt is held on said support track forming a substantially circular, wheel-like traction surface, and can change to a stretching state in which said rollers engage said belt and stretch it from its state in said one traction configuration to a stretched state to define one or more other traction configurations of the system.08-27-2009
20110037311Polymorphic tracked behicle - A method and apparatus is disclosed, for construction and operation of an all terrain polymorphic tracked vehicle. The invention improves on the prior art by providing a mechanism whereby it is possible to vary the shapes of the tracks during operation of the vehicle. This capability facilitates negotiating obstacles and rough terrain, enables such vehicles to climb stairs or similar obstacles, and also enables self leveling of the vehicle on inclined terrain.02-17-2011
305015000 COMBINED OR CONVERTIBLE 3
20100060075Conversion System for a Wheeled Vehicle - A track assembly 30 for converting a wheeled vehicle 10 into a tracked vehicle. The track assembly 30 has a longitudinally adjustable support frame 40 having a motive source 170 with a drive sprocket 190, a plurality of support rollers 80, 84, 88, a tensioning assembly 90, and an endless track 200. The track assembly 30 is connected to a vehicle 10 by articulated, resiliently biased mounting assemblies 210, 410. Each mounting assembly 210, 410 includes a first attachment member 212, 412, a link 250, 450, and a second attachment member 300, 500, with the first attachment member 212, 412 configured to be removably attached to a position on a vehicle 10 where a wheel axle attached to an internal drive unit 19 would normally reside but which has been disconnected from its control lines and removed, and with the second attachment member 300, 500 configured to be connected to the support frame 40. The motive source 170 of the track assembly 30 is connected to and controlled by the same control lines 18 that were previously connected to the internal drive unit 19.03-11-2010
20130033099DEFORMABLE WHEEL ASSEMBLY - A locomotion assembly is provided, suitable to be used in a vehicle. The locomotion assembly comprises a frustum-conical structure comprising at least one flexible member having a frustum-conical surface extending between its relatively narrow and wide ends along a frustum-conical axis, the frustum-conical member being reversibly deformable from its biased rounded shape corresponding to a frustum-conical shape in which its side elevation is circular into a deformed frustum-conical shape in which its side elevation is non-circular. The frustum-conical structure may serve for supporting at least one surface-engaging member convertible between a round wheel-like configuration, in which its side elevation is substantially circular, and a deformed configuration, in which its side elevation is non-circular and in which a larger portion of the surface-engaging member is in contact with a movement surface.02-07-2013
20090243383CONVERSION KIT FOR A TRACKED VEHICLE TO RIDE ON TIRES - The conversion kit changes a conventional tracked excavator into a rubber tired excavator in just a matter of minutes. Thus, a tracked excavator can be driven down the road on pavement without the need for a transport truck and without damaging the pavement.10-01-2009
305001000 STEPPER TYPE 1
20130162015SUPPORT MODULE AND ROBOT HAVING THE SAME - A support module includes a first rigid body, a space formation body connected to the first rigid body and forming an enclosed space, and a plurality of hard particles located within the enclosed space. When at least a predetermined pressure is applied to the support module such that a volume of the enclosed space is decreased to a predetermined value, the plurality of hard particles and space formation body form a second rigid body. Such a support module may improve the stability of a walking robot, the grip of a gripping structure, or the stability of a load-bearing structure.06-27-2013
305006000 RIGID PORTABLE TRACK 1
20120299370CATERPILLAR-TYPE PROPELLING DEVICE FOR A TYRE-BEARING VEHICLE - The invention relates to devices increasing the capacity of vehicles for cross-country travel, and specifically to caterpillar-type propelling devices. The special feature of the caterpillar-type propelling device for a tyre-bearing vehicle, the propelling device containing at least one caterpillar track, the internal surface of which is intended for interaction with the tyres of the vehicle, is that the caterpillar track has limited longitudinal bending internally and provides an internal size of the caterpillar track along the vertical to be greater than the height of the vehicle, and the caterpillar track length is selected to be sufficient to freely encompass the vehicle. The technical result provided by the proposed invention consists in the versatility of use of the propelling device by being capable of being installed virtually on any vehicle without altering and/or modifying the construction of the vehicle. Furthermore, the simplicity of constructing the propelling device, installing the latter on and removing the latter from a vehicle is increased. Furthermore, the proposed propelling device has small dimensions in the dismantled form and is reliable in operation.11-29-2012
