The invention relates to a tracked vehicle () comprising a vehicle body (), at least one track assembly () and a suspension device (S) for suspension of said track assembly () to said vehicle body () of said tracked vehicle (). Said track assembly () comprises a track support beam (), a plurality of road wheels (), at least one drive wheel (), and an endless track (). Said track support beam () is arranged to support said at least one drive wheel () and a plurality of road wheels (). Said endless track is disposed around said at least one drive wheel () and plurality of road wheels (). Said suspension device (S) comprises two pendulum arms () which in one end are rotatably attached to a respective fastening point (P, P) in said vehicle body () and in the other end are rotatably attached to a respective fastening point (P, P) in the track support beam () of said track assembly (). Said suspension device (S) comprises distance adjustment means () which is arranged to allow one or more of: a distance change between said two fastening points (P, P) in the track assembly (); a distance change between the two fastening points (P, P) in the vehicle body (); and a distance change between the fastening point (P, P) in the vehicle body () and the fastening point (P, P) in the track support beam () of said track assembly () of at least one of the pendulum arms (), so as to allow a tilting movement of the track assembly (), including said at least one drive wheel () and plurality of road wheels (), relative to the vehicle body in a plane extending in the longitudinal direction of said track assembly () essentially orthogonal to the transversal extension of said track assembly ().

Tracked vehicle comprising a tiltable suspended track assembly

The invention relates to a tracked vehicle comprising a vehicle body and a track assembly pair. Said track assembly pair is arranged to suspendedly support said vehicle body allowing relative movement between said vehicle body and each track assembly () of said track assembly pair. Each track assembly () comprises a track support beam () configured to support a plurality of road wheels (), a drive wheel (), and a motor () for operating said drive wheel (), an endless track () being disposed around said road wheels () and drive wheel (). Said motor () is fixedly arranged to said track support beam (). Said motor () is arranged in connection to the drive wheel () such that a motor axle essentially coaxially coincides with a centre axis (Z) of the drive wheel ().

Tracked vehicle having motor coaxially arranged with drive wheel

The invention relates to a tracked vehicle () comprising a vehicle body (), at least one track assembly () and a suspension device (S). Said track assembly () is arranged to be supported by said vehicle body () by means of said suspension device (S), said track assembly comprising a track support beam () for supporting a plurality of road wheels (), an endless track () being disposed around said road wheels. Said suspension device (S) comprises a bogie arrangement () rotatably attached to a fastening point (P) of said vehicle body () about an axis of rotation (Z) transversal to the longitudinal extension of said track assembly () and attached to said track support beam () in connection to at least two fastening points (P, P) so that the track support beam () is allowed to rotate in a rotational plane extending along the longitudinal extension of said track support beam () about said axis of rotation.

Tracked vehicle comprising a rotatably attached bogie

A drive unit for a tracked vehicle includes a track support beam, at least one drive wheel, a set of support wheels and an endless track, the drive wheel being arranged to drive the endless track running over the drive wheel and the set of support wheels. The drive wheel and the support wheels are rotatably attached in the track support beam. The drive unit further includes and electric motor attached to the drive wheel and integrated in the track support beam, and a support beam integrated lubrication system having a pump unit arranged for pressurized supply of lubricant to parts of the drive unit in need of lubrication.

Drive unit for tracked vehicle and vehicle provided with drive unit

Annular rotor disc for, in an axially stacked disc assembly of a plurality of similar rotor discs, forming a rotor for an electric motor, in which the discs secure a plurality of axially running permanent bar magnets, of substantially rectangular cross-sectional shape, distributed around the circumference of the rotor. The rotor disc has pockets for accommodating and securing the permanent bar magnets in such a way that adjoining bars form an angle to one another. The pockets for adjacent, mutually diverging permanent bar magnets, viewed in the radial direction from the centre of the rotor, delimit between them a substantially triangular disc part, which is flexibly connected to a radially inner part of the annular rotor disc only by a radically inner web portion.
