| 20120187645 | VEHICLE COMPRISING AT LEAST TWO AXLES, THE WHEELS OF WHICH ARE PARALLEL - A vehicle ( | 07-26-2012 |
| 20140265198 | BOGIE AXLE FOR A MACHINE - An agricultural machine is disclosed. The agricultural machine includes a frame including a first axle on a first side of the frame and a second axle on a second side of the frame; and a bogie axle pivotably mounted on each of the first and second axles of the frame. Each bogie axle includes a body with a front axle disposed at a front end of the body and a rear axle disposed at a rear end of the body. A front tire is mounted on the front axle of each bogie axle and a rear tire is mounted on the rear axle of each bogie axle. The front tire is a different size than the rear tire. | 09-18-2014 |
| 20150054243 | CONVERTIBLE TANDEM AXLE ARRANGEMENT AND METHOD FOR CONVERTING A TANDEM AXLE ARRANGEMENT TO EITHER OF A SINGLE DRIVE OR A DUAL DRIVE TANDEM AXLE ARRANGEMENT - A drive axle system can be converted between a single drive tandem axle arrangement including a rear drive axle a dual drive tandem axle arrangement. A forward bowl is provided for a forward axle system. One of a geared forward carrier and an ungeared forward carrier is mounted on the forward bowl, depending upon whether a dual drive or a single drive tandem axle arrangement is desired. To convert to the other type of tandem axle arrangement, the one of the geared forward carrier and the un geared forward carrier is removed from the forward bowl and replaced, with the other one of the geared forward carrier and the un geared forward carrier. | 02-26-2015 |

| 20130175775 | Skateboard Truck - A skateboard truck assembly with an integrated combination of a system of gears that resemble planetary gears that allow both wheels and a caster to remain on the ground while the skateboard is traveling in a lengthwise manner. At the same time, when the rider leans to one side or the other of the skateboard, the gear assembly causes the “downhill” wheel to rise in the air and the caster to be displaced such that the skateboarder can laterally “slide” or “drift” the skateboard as though it was a snowboard. Because the downhill wheel is raised well above the ground, there is less of a tendency for the downhill wheel to catch on any street irregularities or rocks and stop sliding at inopportune times. | 07-11-2013 |

| 20090146388 | SINGLE CASTER WHEEL ASSEMBLY FOR TRAILER TOWABLE AT HIGH SPEEDS - A trailer wheel assembly for mounting on the rear of a trailer has a structure that reduces or prevents oscillations about a vertical axis arising during high speed towing. The structure includes dual wheels mounted on an axle, a resilient support, and a suspension arm extending rearwardly and downwardly from the resilient support to the axle for the wheels. | 06-11-2009 |
| 20110227304 | SHOCK-PROOF DRAG WHEEL - A shock-proof drag wheel is disclosed. Wherein, on its base is provided with a fixed axis and an indentation portion, a connection rod is disposed on said fixed axis and is connected to an elastic body, and it is swayed and vibrated around said fixed axis. A central axis passes through said connection rod and is located in said indentation portion, and said drag wheel is provided in said indentation portion. When said drag wheel is made to move, the spring force of said elastic body will brake said connection rod in reverse, which in turn bring said central axis into motion in reverse, thus stabilizing said drag wheel and buffering the force generated by the vibrations as caused by said drag wheel passing through uneven ground or indentations on the ground, hereby effectively achieving shock-proof. | 09-22-2011 |
| 20110291373 | Force Steer Axle Assembly With Redundant Centering - A force steer axle assembly is disclosed for providing redundant fail-safe steering control to an axle. The assembly includes a centering cylinder for maintaining the axle in a centered position and for steering the axle as directed. The assembly further includes a hydraulic control system for providing centering and steering actuation to the cylinder, and an electrical control system for receiving user input and controlling the hydraulic system. | 12-01-2011 |
| 20140062043 | DOUBLE-DECKER COACH - A double-decker coach is described which includes a frame, an engine, a front axle and a tandem rear axle. The front axle lies transversely to the principal axis of the frame and offers support to the frame. The front axle includes a pair of steerable wheels, which lie mounted on bearings. The pair of wheels can be steered by a driver. The tandem rear axle lies transversely to the longitudinal direction of the frame and is mounted parallel to the front axle and offers support to the aforesaid frame. The tandem rear axle includes a drive axle and a trailing axle. The drive axle includes two pairs of drive wheels. The drive axle is coupled to the engine. The trailing axle is mounted parallel to the drive axle and includes two pairs of trailing wheels. The ratio of the distance (C) between the third axle and the rear end of the double-decker coach relative to the mutual distance (B) between the front axle and the trailing axle is between 0.20 and 0.50, preferably 0.25 and 0.45, more preferably 0.35 to 0.42, and most preferably approximately 0.39. | 03-06-2014 |
