Abstract

A power transmission assembly includes a base, a rotating frame rotatably coupled to the base and configured to rotate about an axis, an output shaft coupled to the rotating frame, a weight selectively repositionable relative to the rotating frame, and a weight actuator configured to reposition the weight relative to the rotating frame to move the weight from a subtraction position located at a first height to an addition position located at a second height. The second height is greater than the first height such that a gravitational force on the weight drives the rotating frame to rotate about the axis and drive the output shaft.

Abstract

Devices, systems, and methods are described that provide an braking system for a motor vehicle. The braking system extends a friction device from beneath the vehicle to contact the driving surface. Orientation of the friction device and forces applied to the braking device can be adjusted during the braking procedure. In some braking devices forces generated during braking are directed to a load bearing arm and supporting frame, thereby minimizing damage to actuating devices. The friction device can be retracted after use, permitting normal vehicle operation.
