| 280426000 | Steering by articulative movement | 9 |
| 20090020982 | Trailer steering mechanism - A mechanism for steering one or more axles of a multi-axle trailer and cutting the air supply to the air suspension system on some of said axles when the steering mechanism cannot match the angle of the tractor by utilizing cams keyed to the tractor fifth wheel. | 01-22-2009 |
| 20090236823 | Operation of Self-Steering Axles on Semi-Trailers - A method of controlling the sideways motion of a trailer forming part of a combination vehicle, such as a road train, for road transport of heavy goods. The vehicle has a trailer including a semi-trailer body and a dolly mounted beneath the front of the semi-trailer body. The method includes steering at least some of the wheels on said axle sets relative to the dolly frame such that at high speeds, as the vehicle turns towards one side, steering the dolly wheels to induce the dolly to move towards that side and, at low speeds, as said vehicle turns towards that side, steering the dolly wheels to induce the dolly to move towards the opposite side. | 09-24-2009 |
| 20100032923 | SEMI-TRAILER REPOSITIONER - Exemplary apparatus and system for repositioning a semi-trailer are described. The repositoner may comprise two pivoting arms, each comprising a mechanical actuator attached to an underside area of the semi-trailer, wherein the pivoting arms are disposed substantially parallel to the underside of the semi-trailer in a first position and are configured to be pivoted away from the semi-trailer in a second position substantially perpendicular to the underside of the semi-trailer; two wheels mounted at an angle from a rear plane of the semi-trailer such that the semi-trailer moves in a circular path when the wheels turn, with each wheel operatively coupled to a motor; and a lower frame mounted to the mechanical actuators of the arms, the lower frame comprising two opposing wheel housing couple to the wheels; wherein, lowering the hydraulic jack arms can hydraulically lift the semi-trailer, and further wherein the wheels can maneuver the semi-trailer. | 02-11-2010 |
| 20130175785 | STEERING MECHANISM FOR A DRAWN VEHICLE TO STEER ONE OR MORE TURNABLE STEERED AXLES - A steering mechanism for a drawn vehicle to steer one or more turnable steered axles that at least has a slewing bearing, a rocker that is fitted around a vertical shaft and is turnable, a cable whose ends are connected to the rocker on either side of the vertical shaft and which is fitted around the slewing bearing to transmit a turn of the slewing bearing to the rocker and a tackle at each end of the cable with a fixed pulley that can be coupled to the drawn vehicle, and a movable pulley on the rocker. | 07-11-2013 |
| 20140091553 | Lowboy Trailer with Steerable Rear Assembly - A steerable rear assembly is disclosed for a lowboy trailer. The assembly includes a lowboy trailer deck and a neck extending partially upwardly rearward and partially horizontally rearward from the deck. A front bogey is positioned beneath the horizontally extending portion of the neck, and the front bogey is connected to the neck by a horizontal pivot between the neck and the front bogey and by a turntable between the neck and the front bogey. A rear bogey is positioned behind the front bogey and is connected to the front bogey by a vertical pivot between the front and rear bogeys. | 04-03-2014 |
| 20140131977 | DRIVING SUPPORT DEVICE AND DRIVING SUPPORT SYSTEM - A driving support device for a first trailer coupling vehicle including a first trailer and a first towing vehicle includes: a leading vehicle driving status obtaining device for obtaining a driving status of a second trailer coupling vehicle; a first towing vehicle driving status obtaining device for successively obtaining a driving status of the first towing vehicle; a first trailer driving status obtaining device for successively obtaining a driving status of the first trailer; and a support device for supporting a driver of the first trailer coupling vehicle so as to bring the driving status of the first towing vehicle and the driving status of the first trailer closer to the driving status of a second towing vehicle and the driving status of a second trailer, respectively, when the first trailer coupling vehicle changes in direction. | 05-15-2014 |
| 20140265243 | STEERABLE TRAILER CHASSIS - A steerable trailer provides the ability to offset the center line of the trailer to the tow vehicle with a swivel tung and pivoting axels. The steerable trailer can alter the turning radius of the trailer and improve the turning and backing of the trailer. Typically, a trailer moves relative to the tow vehicle. The steerable trailer allows a user to control the trailer steering independently from the tow vehicle and adds up to two more points to steer more accurately and safely in close areas, for example. The swiveling tung and pivoting axels can be used independently or together to position the trailer safely in different radii. | 09-18-2014 |
| 20140284900 | STEERING SYSTEM FOR TRAILERS - A method of controlling a combination vehicle for road transport of heavy goods, said vehicle comprising a motor vehicle at the front and a trailer attached so as to be towed behind the motor vehicle, said trailer comprising:
| 09-25-2014 |
| 20150291213 | SELF-STEERING BOGIE FOR A ROAD VEHICLE - A self-steering bogie for an elongate road vehicle having at least a first axle assembly at the front end of the vehicle and at least one trailing axle assembly disposed on the vehicle behind said first axle assembly. The trailing axle assembly is a set of tandem axles with associated wheels disposed below a structural frame of the vehicle, the bogie comprising a rotatable sub-frame borne on the set of tandem axles which supports the vehicle by means of a load bearing turntable. A rotational restraint assembly is mounted on the turntable and which in part interconnects the sub-frame, the structural frame and an upper portion of the turntable, the rotational restraint assembly having a plurality of compression air springs. The elongate road vehicle could be a truck and semitrailer where the trailing axle assembly is on the semitrailer, or a vehicle such as a bus. | 10-15-2015 |
