180900440 | With track-related steering means | 11 |
20090095544 | Remotely controlled vehicle with a track mechanism and independently operated wheels - A remotely controlled vehicle with a track mechanism and independently operated wheels is described. The vehicle includes a track assembly that includes a center track drive wheel and corresponding endless center track. A pair of driving wheels are mounted on opposing lateral sides of the track assembly. Two independently operated motors are included, each supplying power to only one of the driving wheels. A differential gear set is operatively connected between each of the two motors and the center track drive wheel. The gear set is formed to drive the center track drive wheel in a vehicle driving direction when both motors are concurrently operated to drive the pair of driving wheels in the vehicle driving direction. The gear set also imparts a minimal force to the center track drive wheel when each of the motors are operating to drive the pair of driving wheels in opposing directions. | 04-16-2009 |
20100230185 | ENDLESS BELT DRIVE FOR A VEHICLE - A drive system has a drive-system frame operatively connectable to a vehicle. The drive-system frame is capable of pivotal movement relative to the longitudinal axis of the vehicle to steer the vehicle. The drive-system frame is incapable of pivotal movement with respect to the frame of the vehicle in a plane parallel to the longitudinal axis and normal to the ground when the vehicle is on flat level terrain and steered straight. A rail is pivotally mounted to the drive-system frame. A ground-engaging endless belt is in sliding engagement with the rail. The belt is operatively connectable to an engine to propel the vehicle. The drive system is operatively connectable to the steering device of the vehicle. A steering angle stopper is disposed on the vehicle such that a steering linkage of the vehicle does not bear a force created when the stopper is engaged. A vehicle is also described. | 09-16-2010 |
20110036650 | MULTI-PURPOSE GROUND VEHICLE - The invention relates to a multi-purpose ground vehicle ( | 02-17-2011 |
20160068186 | STEERING DEVICE AND ARTICULATED VEHICLE PROVIDED WITH STEERING DEVICE - The invention relates to a steering device for an articulated tracked vehicle comprising a front and a rear vehicle unit, wherein said steering device comprises a substantially vertical steering link about whose axis said front and rear vehicle units are pivotable, The vertical steering link is arranged substantially centrally of the front vehicle unit, and the steering device comprises a steering bearing configuration comprising an outer bearing ring arranged to be attached to a centre beam of said front vehicle unit, and an inner bearing ring rotatably arranged relative to said outer bearing ring via a bearing about the axis of the steering link. | 03-10-2016 |
20160083026 | LOAD-CARRYING FRAME AND VEHICLE PROVIDED WITH LOAD-CARRYING FRAME - The invention relates to load-carrying frame for carrying load of an articulated tracked vehicle comprising a front and a rear vehicle unit connected to each other through said load-carrying frame, wherein said front vehicle unit comprises a rolling link. The load-carrying frame is configured for rotatable attachment to the front vehicle unit via said rolling link for enabling rotation of the front vehicle unit relative to the load-carrying frame about an axis of said rolling link running in the axial main direction of extension of said load-carrying frame. | 03-24-2016 |
20160083027 | ARTICULATED VEHICLE - The invention relates to an articulated vehicle comprising a front and a rear vehicle unit, and at least one further vehicle unit connected to said rear vehicle unit, comprising a front vertical steering link arranged substantially centrally of the front vehicle unit, where said front vertical steering link is configured for pivotal attachment to a fixed load-carrying frame connecting said front and rear vehicle units, where said at least one further vehicle unit is configured for attachment to a further fixed load-carrying frame, where said further fixed load-carrying frame is releasably connectable to said fixed load-carrying frame for said connection, such that a train of vehicle units is formed connected to a load-carrying frame unit comprising said fixed load-carrying frame and said further fixed load-carrying frame. | 03-24-2016 |

20100147603 | ROLLOVER PROTECTION CAB - Embodiments of the present invention generally relate to a rollover protection cab. In one embodiment, a rollover protection cab for a construction vehicle includes a structural frame defining cabin space for a vehicle operator. The structural frame is operable to substantially maintain the cabin space while withstanding a crushing load greater than or equal to twenty tons. The cab further includes a window; a door; a seat disposed in the cabin space; and controls for operating the vehicle disposed in the cabin space. | 06-17-2010 |
20130000996 | MOBILE MACHINE WITH A SUPPORT SYSTEM - A mobile machine includes a frame and a support system for supporting the frame from a ground surface underlying the support system. The support system may include a swing member pivotally engaged to the frame. The support system may also include journal structure rigidly attached to the swing member. The support system may further include a strut engaged to the journal structure in a manner allowing rotation of the strut relative to the journal structure about a central axis of the strut. Additionally, the support system may include a ground-engaging component mounted to the strut, the ground-engaging component being configured to move along the ground surface. The support system may also include a steering actuator engaged to the frame and the strut to control rotation of the strut about its central axis and thereby control a steering angle of the ground-engaging device relative to the frame. | 01-03-2013 |
20130015006 | SNOWMOBILE HAVING FRONT TRACKS WITH BRAKES - A central endless drive track is disposed below the seat of a snowmobile. At least two left wheels are operatively connected to a left track frame disposed forwardly of the seat. A left track engages the left wheels. A left brake is connected to the left track frame and selectively engages one of a first left wheel and the left track to brake the left track. At least two right wheels are operatively connected to a right track frame disposed forwardly of the seat. A right track is disposed around the right wheels. A right brake is connected to the right track frame and selectively engages one of a first right wheel and the right track to brake the right track. A brake lever causes the left and right brakes to brake the left and right tracks respectively. | 01-17-2013 |
20140374175 | Apparatus for Converting a Wheeled Vehicle to a Tracked Vehicle - The invention relates to track systems | 12-25-2014 |
20150321709 | Tracked Vehicle - A track system for steerable vehicles having at least one axle. The track system is capable of adjusting to changes in terrain by pivoting in clockwise and counterclockwise directions relative to an axle assembly as the vehicle moves across the ground. The pivotal movement of the track system relative to the axle assembly is restricted by a limiter attached to an inboard member of the track system frame. Pivotal movement is limited by the axle assembly housing engaging the limiter when the track system pivots in either a clockwise or counterclockwise direction to a maximum point along a pivot arc. | 11-12-2015 |
