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 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.
