A freight vehicle has a frame defining a support surface for the goods to be transported, a plurality of rubberized wheel assemblies with suspensions, the height of which can be adjusted to shift the support surface between a lowered loading position and a raised transport position, and a driver's cab arranged beneath said support surface; the cab being coupled to, and overhanging, the frame by means of an articulated quadrilateral transmission unit and being shifted by pneumatic actuators configured to vertically move the whole cab in relation to the support surface between two extreme end positions, one approaching the support surface and one spaced apart from said support surface, and to arrange the cab in a cushioned intermediate position for the transport of the goods.

In a vehicle subframe 1, a first side member has a first extending portion that extends while being deflected outward on one side in a width direction as approaching from a rear side to a front side, a second side member has a second extending portion that extends while being deflected outward on the other side in the width direction as approaching from the rear side to the front side, and a second cross member is further included which is opposed to the first cross member on the front side thereof and couples a portion of the first extending portion in which the degree of outward deflection on the one side in the width direction becomes large and a portion of the second extending portion in which the degree of outward deflection on the other side in the width direction becomes large to each other.

An off-highway vehicle may include an off-highway vehicle frame and a motor carried by the off-highway vehicle frame. The off-highway vehicle may also include wheel assemblies rotatably coupled to the off-highway vehicle frame without an intervening vehicle suspension and at least some of the wheel assemblies being driven by the motor. Each of the wheel assemblies may include an inner rim coupled to the hub, an outer rim surrounding the inner rim, and gas springs coupled between the inner rim and the outer rim to provide a gas suspension for relative movement between the inner and outer rims.

A vehicle battery pack support device applicable to various classes of vehicles and allowing weight reduction and cost reduction. The vehicle battery pack support device suspends a battery pack at a side rail constituting a ladder frame of a vehicle and includes a frame-side bracket secured by bolts to an outer side face of the side rail at a plurality of bolt fastening parts thereof arrayed in a grid arrangement. An elastic coupling part elastically couples the battery pack and the frame-side bracket. A spacer is interposed between the outer side face of the side rail and the frame-side bracket. The spacer includes a plurality of columnar members corresponding to the plurality of bolt fastening parts and a connecting part that connects the plurality of columnar members.

On both sides under a floor of an electric vehicle, side members are provided, each in a closed cross sectional shape. Collars and the like are provided in the side members. On a lower side of a lower wall of each of the side members, cross members which are fixed by using the collars or the like are provided. Between the side members on both sides, a main battery is provided and supported by the cross members. In the vicinity of a lower side of a doorway of the electric vehicle, a cutout part is formed such that a height of a portion of an upper wall of the side member is relatively lowered. On an upper surface of the cutout part, a reinforcing member is provided. A ramp passes through a space on an upper side of the cutout part.

A vehicle skeleton structure includes: a first front pillar portion provided at a first side portion of a vehicle body; a second front pillar portion provided at a second side portion of the vehicle body; a front upper cross portion coupled to upper portions of the first and second front pillar portions; a front lower cross portion coupled to lower portions of the first and second front pillar portions; a first rear pillar portion provided at the first side portion along a rear peripheral edge portion of the door opening portion; a second rear pillar portion provided at the second side portion; a rear upper cross portion coupled to upper portions of the first and second rear pillar portions; and a rear lower cross portion coupled to lower portions of the first and second rear pillar portions.

A vehicle battery pack support device for a battery pack mounted below a pair of side rails extending in a vehicle longitudinal direction and has a pair of side faces each facing in the longitudinal direction, includes a battery bracket for housing the battery pack and a frame bracket for coupling the side rails and the battery bracket. The battery bracket includes a first bracket covering the side faces of the battery pack, at least a portion of a top face that is continuous with the side faces, and at least a portion of a bottom face that is continuous with the side faces, the first bracket having a dimension in the vehicle width direction which is equal to or larger than the long side of the battery pack and a second bracket covering an end portion of the first bracket in the width direction coupled to the frame bracket.

A hollow-chamber profile for fastening a battery module in a vehicle includes a first side wall and a second side wall which lies opposite the first side wall, where the first side wall and the second side wall are connected to one another via a bottom wall. Additionally, the hollow-chamber profile has a top wall which lies opposite the bottom wall, where the top wall is designed to interact with at least one fastening device for fastening the battery module. The hollow-chamber profile has at least one intermediate wall which extends between the side walls from the top wall in the direction of the bottom wall, where a wall thickness of the at least one intermediate wall is dimensioned in such a way that the fastening device can be introduced at least partially into the wall thickness of the at least one intermediate wall.
