Publication number: 20240025477Abstract: A steering knuckle gearbox assembly comprises a body having a housing portion having a cavity defined in the housing portion; a mating portion connected to the housing portion and being pivotably mountable an axle frame of a vehicle; and a mounting portion for having a steering link of the vehicle pivotably mounted to the mounting portion. An input shaft is rotationally supported by the housing portion and extends into the cavity at its one end and is operatively connectable to a drive axle of the vehicle at its other end. An output shaft is rotationally supported by the housing portion and extends into the cavity at its one end and is operatively connected to the input shaft at its other end. The output shaft is offset in height from the input shaft. A steerable track system for a vehicle is also described.Type: ApplicationFiled: October 2, 2023Publication date: January 25, 2024Inventors: Pierre-Yves PEPIN, Steve FRECHETTE, Keven BOUTIN, Charles ST-ARNAUD, Frederik MARTEL, Nicolas DUBUC, Andre LEGER, Pascal LAFRENIERE

Patent number: 11286013Abstract: A track system comprising a dynamic tensioning device located between an idler wheel and the support frame as to apply proper tension in the track. The dynamic tensioning device is adapted to block at its current length upon the occurrence of a determined condition. The dynamic tensioner is adapted to substantially maintain its length when an acceleration and or deceleration of the track system reaches a predetermined value. For instance, such characteristic is relevant in an event of emergency braking. A dynamic tensioner would become contracted and the tension in the endless track would become too low. A low tension could cause the endless track to ratchet.Type: GrantFiled: March 19, 2020Date of Patent: March 29, 2022Assignee: SOUCY INTERNATIONAL INC.Inventors: Yves Sauvageau, Andre Leger

Patent number: 10640162Abstract: Endless track system tensioning system comprising: Tensioner having a cylinder and a piston within the cylinder forming a variable volume chamber containing liquid. Reservoir containing liquid and gas fluidly connected to the cylinder chamber. Conduit fluidly connected between the chamber and the reservoir allowing liquid to flow therebetween to move a position of the piston. The gas applying hydrostatic pressure to liquid biasing the piston toward an extended position, biasing an idler wheel assembly against an endless track. Valve disposed along the conduit for controlling liquid flow through the conduit, movable between: Open position in which liquid is allowed to flow, rendering piston movable, allowing for relative movement between a frame and an idler wheel assembly. Closed position in which liquid is prevented from flowing rendering piston effectively immovable within the chamber, effectively preventing relative movement between frame and idler wheel assembly.Type: GrantFiled: October 13, 2017Date of Patent: May 5, 2020Assignee: SOUCY INTERNATIONAL INC.Inventors: Yves Sauvageau, Andre Leger

Patent number: 9505432Abstract: A steering knuckle to be used with the steering assembly of a vehicle such as a farming tractor is disclosed. The steering knuckle comprises preconfigured attachment areas where attachment element(s) or bracket(s) can be releasably yet rigidly secured. The attachment areas may be further reinforced with additional knuckle material (e.g. metal, metallic alloy). The steering knuckle therefore provides predetermined and preconfigured attachment location(s) where a wheel-replacing track system can be secured, thereby allowing the track system to be mounted to the vehicle while avoiding attachment at inconvenient or weak locations.Type: GrantFiled: October 26, 2015Date of Patent: November 29, 2016Inventors: Steeve Pare, Steve Frechette, Serge Latulippe, William Gasse, Andre Leger, Andre Todd, Nicolas Dubuc

Patent number: 8911031Abstract: This invention generally relates to track systems and traction assemblies for use as wheel replacement for normally wheeled vehicles. The track system uses a traction band disposed about a sprocket wheel, idler wheels and road wheels for propulsion. The idler wheels and road wheels are typically pivotally mounted to a support frame, itself configured to be coupled to the sprocket wheel via a support member. The track system also comprises a movement limiting link mounted both to the support member and to the vehicle frame. The movement limiting link limits longitudinal and lateral movements of the track system, such as to prevent contact between the track system and the vehicle.Type: GrantFiled: June 30, 2010Date of Patent: December 16, 2014Assignee: Soucy International Inc.Inventors: Robert Bessette, Louis-Frédéric Marchildon, Steve Fréchette, Jonathan Thibault, André Léger
