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

The present invention relates to an electrical drive arrangement for driving a motor vehicle comprising an electric motor, a drive shaft driven by means of the electric motor, a housing in which the electric motor is accommodated, which housing has an envelope surface and a substantially annular cross section wherein the horizontal direction of the envelope surface of said housing and hereby said drive shaft are arranged to run substantially transverse to the longitudinal direction of said vehicle, comprising a pendulum suspension for suspension of the electrical drive arrangement, where the pendulum suspension comprises a fastening configuration fixedly connected to the vehicle and at least one pendulum attachment fixedly connected to the envelope surface of the housing and pivotally journaled relative to said fastening configuration by means of a bearing configuration. The invention also relates to a motor vehicle.
