A system for detachably coupling subassemblies to vehicles or other components is discussed herein. The system can include one or more driveshafts and worm drives to drive fasteners to couple the subassembly to the vehicle. The system can enable drive interfaces located in a substantially conventional location (e.g., located vertically on the bottom of the vehicle) to drive fasteners horizontally into the body or other subassembly. In this manner, fasteners can be hidden and to utilize blind holes in the body of the vehicle. The system can be partially disassembled in situ to enable parts replacement and fastener access in the event of a failure. The system can be used in conjunction with a robotic cart to enable subassemblies to be removed from the vehicle for service and repair. A portion of the system can also act as a portion of, or to reinforce, the crash structure of the vehicle.

A method for joining a drivetrain to a vehicle body, includes the steps of: transferring the drivetrain and the vehicle body into a joining position, arranging an electrical connecting element on a chassis part of the drivetrain, and joining the drivetrain to the vehicle body, wherein the drivetrain and the vehicle body are connected together at predetermined points via fasteners.

A modular chassis is provided for an off-road vehicle to improve assembly, servicing, and repairing of a drivetrain of the off-road vehicle. The modular chassis includes a chassis to support components of the off-road vehicle. A front frame module couples with a front of the chassis, and a rear frame module couples with a rear of the chassis. The front frame module supports lower suspension arms of the off-road vehicle by way of inboard bushing joints. The front frame module supports at least a steering gear and a front differential of the off-road vehicle. The rear frame module is a tube-frame structure that supports components of the off-road vehicle. A lower portion of the rear frame module extends rearward and acutely upward to a top frame member that couples with upper side portions of the chassis. Several cross-members impart structural integrity to the rear frame module.
