Modular vehicle construction and transportation system
First Claim
1. A modular vehicle for providing transportation, said vehicle comprising:
- (a) a preassembled self-supporting undercarriage module, said undercarriage module including;
(i) wheels for providing full support for said undercarriage module on a travelling surface and for enabling travel of said vehicle on said surface;
(ii) a compartment for holding a power source for supplying operating power to said vehicle, said compartment including a cover normally enclosing said power source from above, said cover being removable for permitting the servicing of said power source while said power source remains in situ in said compartment; and
,(iii) means for directing controlled motive power from said power source to at least one of said wheels;
(b) a preassembled self-supporting overcarriage module normally carried wholly atop said undercarriage module, said overcarriage module including control means linkable with said undercarriage module for controlling operation of said vehicle; and
,(c) coupling means for releasably coupling said overcarriage module to said undercarriage module, said control means linking with said undercarriage module when said modules are so coupled.

Abstract
A modular vehicle comprises a preassembled undercarriage module, a preassembled overcarriage module, and coupling means for releasably coupling the overcarriage module to the undercarriage module. The undercarriage module includes wheels for permitting travel of the vehicle on a travelling surface, means for holding a power source for supplying operating power to the vehicle, and means for directing controlled motive power from the power source to at least one of the wheels. The overcarriage module includes control means linkable with the undercarriage module for controlling operation of the vehicle. When the power source associated with a first undercarriage module is in need of maintenance service, there is provided a method of handling an overcarriage module coupled to the first undercarriage module comprising the steps of decoupling and separating the two modules; then releasably coupling the overcarriage module to a second one of such undercarriage modules, the associated power source of the second undercarriage module not being in need of maintenance service; then operating the overcarriage module and the second undercarriage module together as a vehicle while providing the maintenance service required by the power source of the first undercarriage module.

9. In a vehicle transportation system comprising a plurality of preassembled self-supporting vehicle undercarriage modules and a plurality of preassembled self-supporting vehicle overcarriage modules wherein:
-
any selected one of said overcarriage modules is releasably couplable wholly atop any selected one of said undercarriage modules for operation of said selected modules together as a vehicle; each of said undercarriage modules includes an associated power source in the module for supplying vehicle operating power; a first one of said overcarriage modules is releasably coupled to a first one of said undercarriage modules, the associated power source of said first undercarriage module being in need of maintenance service, a method of handling said first overcarriage module and said first undercarriage module at a predetermined site, said method comprising the steps of; (a) decoupling and separating said first overcarriage module from said first undercarriage module;
then,(b) releasably coupling said first overcarriage module wholly atop a second one of said undercarriage modules, the associated power source of said second undercarriage module not being in need of maintenance service; (c) linking with said second undercarriage module a control means included with said first overcarriage module for controlling operation of said first overcarriage module and said second undercarriage module together as a vehicle; (d) providing maintenance service to the associated power source of said first undercarriage module while the same remains in situ in said first undercarriage module; and
,(e) after providing said service, making said first undercarriage module available at said site for subsequent exchange with any of said other undercarriage modules. - View Dependent Claims (10, 11, 12)

13. In a vehicle transportation system comprising a plurality of preassembled self-supporting vehicle undercarriage modules and a preassembled self-supporting vehicle overcarriage module releasably coupled wholly atop a first one of said undercarriage modules for operation together with said first undercarriage module as a vehicle, each undercarriage module including an associated power source in said module for supplying vehicle operating power, each such power source being in need of periodic maintenance service, a method of exchanging a second one of said undercarriage modules for said first undercarriage module and providing maintenance service to the associated power source of said first undercarriage module, said method comprising the steps of:
-
(a) driving said first undercarriage module with said overcarriage module coupled thereto to a module exchange site; (b) then decoupling said overcarriage module from said first undercarriage module; (c) then separating said overcarriage module and said first undercarriage module to permit coupling alignment between said overcarriage module and said second undercarriage module; (d) then positioning said overcarriage module and said second undercarriage module in coupling alignment; (e) then releasably coupling said overcarriage module wholly atop said second undercarriage module, and linking with said second undercarriage module a control means included with said overcarriage module for controlling operation of said overcarriage module and said second undercarriage module together as a vehicle; (f) then driving said second undercarriage module with said overcarriage module coupled thereto away from said exchange site; and
,(g) after said separating step, providing maintenance service to said associated power source of said first undercarriage module while the same remains in situ in said first undercarriage module and then making said first undercarriage module available for subsequent exchange with any of said other undercarriage modules. - View Dependent Claims (14, 15, 16, 17)
