The present invention relates to a wheelbase structure (configured to form at least a part of a vehicle main supporting structure by extending from a first axle to a second axle, the first and second axles being separated along a longitudinal direction. The wheelbase structure comprises an outer boundary forming an inner housing space for housing energy storage or transformation devices, wherein at least a portion of the outer boundary is formed by a sandwich structure comprising a plurality of layers of different material.

Wheelbase structure

The present disclosure relates to an energy storage compartment connectable between a pair of longitudinally extending frame rails of a heavy-duty vehicle, the energy storage compartment being arranged to house an energy storage system configured to supply energy to a prime mover of the vehicle for propulsion of the prime mover, wherein the energy storage compartment comprises longitudinally extending portions forming an encircling load absorbing module, the longitudinally extending portions comprising a pair of longitudinally extending side wall portions connectable to the pair of longitudinally extending frame rails, a longitudinally extending floor portion and a longitudinally extending roof portion, wherein the longitudinally extending portions of the encircling load absorbing module are arranged and configured to, when being subject to a load from the longitudinally extending frame rails, absorb the transversal component of the load.

Energy storage compartment

The present invention relates to a method for moving a heavy object into a confined space. The method comprises providing the heavy object in an initial position, the heavy object having an underside resting on a ground surface and comprising an inducible gas-cushion arrangement which in its inactive state causes the underside of the heavy object to maintain contact with the ground surface; activating the inducible gas-cushion arrangement by forming a gas cushion between the underside of the heavy object and the ground surface, the gas cushion generating a lifting force causing the underside of the heavy object to lose contact with the ground surface; moving the heavy object relative to the confined space until the underside of the heavy object at least levels with the supporting surface of the confined space; and moving the heavy object into its final position utilizing the lifting force of the gas-cushion.

Method for moving a heavy object

A bushing for a wheel suspension adapted to connect a control bar to a structure of a vehicle, where the bushing comprises a first rotational center for the control bar having a first angular rotation range, where the bushing comprises a second rotational center for rotational angles outside of the first angular rotation range.

Bushing for a suspension and vehicle comprising such a bushing

The present disclosure relates to a battery assembly for a vehicle comprising a pair of longitudinally extending frame rails, the battery assembly comprising a first and a second vehicle battery module, the first vehicle battery module being stacked vertically on top of the second vehicle battery, wherein the battery assembly is configured to be connected to the vehicle vertically below the frame rails by attaching an upper surface of the first vehicle battery module to a horizontally extending portion of a pair of brackets, the pair of brackets being attachable to a respective one of the longitudinally extending frame rails.
