A snow bike track assembly includes a frame assembly, at least one strut, an endless track, a plurality of top and bottom rollers, a skid rail assembly, a drive assembly, and a swing arm assembly. The frame assembly is configured to connect to a frame of a motorcycle in place of a rear wheel of the motorcycle. The at least one strut is connected to the frame assembly and configured to connect to the motorcycle frame in place of a rear shock of the motorcycle. The plurality of top rollers are mounted to the frame assembly and arranged to support the endless track. The plurality of lower rollers are mounted to the skid rail assembly and arranged to support the endless track. The drive assembly is configured to drive the endless track. The swing arm assembly is coupled between the frame assembly and the skid rail assembly.

A compact tracked vehicle relates to the field of transport technologies, in particular to compact tracked electric vehicles intended for use on rough surfaces (snow, sand, gravel, dirt), the claimed device may be used in combination with different types of pull-type and attachable equipment for purposes of entertainment, as a part of robotic platforms, and for human and small cargo transportation. A technical effect achieved by the claimed technical solution is reducing dimension and weight characteristics of a tracked vehicle and simplification of its structure by means of a compact tracked vehicle characterised in that it comprises a frame, an electric motor, a track, support rollers, and a traction wheel, wherein an electric motor shaft is fixed with respect to the frame, an electric motor housing is rotatably positioned with respect to the shaft, and the traction wheel is co-axial to the electric motor shaft and arranged for simultaneous rotation with the electric motor housing; the electric motor is double sided; the traction wheel is annular, provided with outer grips, and positioned directly on the electronic motor housing; the vehicle further comprises rechargable baterries; and a platform positioned on the frame and equipped with fastening means for an external equipment.

A steering system of a vehicle is provided. The steering system adjusts the torsional rigidity of a torsion bar without limitation as to the configuration thereof and performs active control responding to the vehicle state by adjusting steering characteristics by controlling the torsional rigidity of the torsion bar based on the traveling condition, load state or driving mode of the vehicle. The steering system includes an MR assist device, which is coupled to an end portion of the torsion bar and adjusts the rotation and torsional rigidity of the torsion bar using an MR fluid as a working fluid.

Track system for a vehicle having a chassis and a drive shaft extending laterally outwardly from the chassis includes: An attachment assembly having a pivot. A multi-member frame assembly including: a leading frame member pivotably connected to the attachment assembly via the pivot for pivoting about a pivot axis; a trailing frame member pivotably connected to the attachment assembly via the pivot for pivoting about the pivot axis; a leading wheel-bearing frame member at least indirectly pivotably connected to the leading frame member; a trailing wheel-bearing frame member at least indirectly pivotably connected to the trailing frame member. A damper interconnecting the leading frame member and the trailing frame member. A leading idler wheel assembly; a trailing idler wheel assembly; support wheel assemblies; a gearbox; a sprocket wheel; and an endless track.

A leading idler wheel assembly; a trailing idler wheel assembly; support wheel assemblies; a gearbox; a sprocket wheel; and an endless track.

A track wheel suspension for a construction machine is introduced. The track wheel suspension includes a track wheel engageable to a track and a swing device including a first coupling portion. The first coupling portion is arranged for rotatably supporting the track wheel. Furthermore, the track 5 wheel suspension including a swing bar with a first bar end which is arranged for being mounted to a second coupling portion of the swing device. The swing bar provides a swing axis which is offset from a rotation axis of the track wheel such that a swing movement of the swing device enables a movement of the track wheel in a direction which is substantially perpendicular to the rotation axis.

An undercarriage assembly for a work machine including a drive wheel; a front idler wheel rotatable on a front axle; a rear idler wheel rotatable on a rear axle; an endless track belt about the drive and idler wheels; a number of mid-rollers located between the front and rear idler wheels to engage the endless track belt on a lower run; a track roller frame pivotably mounted on the work machine at a main pivot, including an elongate member with a front end and a rear end with the main pivot located between the front end and the rear end and the front idler wheel connected near the front end of the track roller frame; a major bogie including forward and trailing bogie arms, the major bogie pivotably connected to the track roller frame at a major bogie pivot, and the rear idler wheel connected to the trailing bogie arm; a minor bogie, mounted on the forward bogie arm, the minor bogie pivotably connected to the major bogie at a minor bogie pivot, and including a minor bogie suspension, a minor bogie front axle, a minor bogie rear axle, the minor bogie front and rear axles supported by the minor bogie suspension, and the minor bogie suspension providing damping between the minor bogie front and rear axles and the minor bogie pivot.
