A motor vehicle and construction method for a motor vehicle, such as a bus, wherein fabricated subassemblies or modules are joined using mechanical fasteners to form an integrated, load carrying structure. The fabricated subassemblies are configured to allow substitution of subassemblies with alternative configurations in order to produce a number of unique vehicle configurations each sharing a common architecture. Modular construction techniques allow for simplification of construction processes, reduction of welding processes, and the application of physically smaller subassemblies. Interchange and substitution of subassemblies with shared attributes may also facilitate production of vehicles having different characteristics.

Disclosed herein is an apparatus for changing a traction motor and a wheel assembly out of a locomotive. The apparatus is suitable for use in the field. The apparatus comprises: (i) a frame that is dimensioned to fit under the locomotive and within a railroad track; (ii) a wheel-assembly-support system that is configured to support the wheel assembly such that the wheel assembly is clear of the track; (iii) a traction-motor-positioning system that is operable to position the traction motor with respect to the locomotive; and (iv) a drive assembly that is configured to drive the fame, the wheel-assembly-support system, and the traction-motor-positioning system under the locomotive in a reversible manner. The wheel-assembly-support system, the traction-motor-positioning system, and/or the drive assembly is/are operable by way of a remote control. Methods of changing a traction motor and/or wheel assembly out of a locomotive on a track are also provided.

Suitable for frame vehicles, the kit provides a frame to be mounted on the chassis with attachment devices at a head section and at a middle section of the frame that supports an electric motor, a transmission and at least one battery system. Replacement of the conventional engine and transmission by the frame-mounted unit can be fast. The frame can be attached at the middle section using shear bolts to avoid impeding a crumple of the chassis during a front impact.

An electric-drive vehicle structure is provided, which includes a cross member bridged between side frames in a front part of a vehicle, a motor suspended below the cross member, a tray fixed to an upper surface of the cross member, and an electric unit for driving a motor, fixed onto the tray. A front edge of the electric unit is located forward of a front edge of the cross member, and the tray has a front edge located, throughout a width thereof, forward of the electric unit.

A dump truck includes: a vehicle body frame; a body supported by the vehicle body frame and configured to be raised or lowered; a plurality of tires provided to the vehicle body frame; an electric motor configured to drive the tires; and a cooling blower configured to feed a cooling air to the electric motor, in which the vehicle body frame at least partially includes a hollow part, and the hollow part defines a duct through which the cooling air passes.

A vehicle for variably sized transportation may include a vehicle basis and exterior elements coupled to the vehicle basis. At least some exterior elements may be collapsible or movably coupled to the vehicle basis at a first set of positions or a first set of extended or collapsed states to form a first operational configuration, or at a second set of positions or a second set of extended or collapsed states to form a second operational configuration. The first or second operational configuration may provide for a first or second shadow and a first or second passenger or cargo space for the vehicle. The first and second shadows and the first and second passenger or cargo spaces may differ in at least their longitudinal dimensions or in latitudinal dimensions. Other embodiments may also be described and claimed.
