Abstract: In one aspect of the present disclosure, a disc brake rotor assembly is provided that includes a disc brake rotor and a wheel hub. One of the disc brake rotor and the wheel hub includes a plurality of pairs of partial keyways and the other of the disc brake rotor and the wheel hub includes intermediate partial keyways configured to fit intermediate the pairs of partial keyways to form keyways. The disc brake rotor assembly further includes a plurality of fasteners configured to be received in the keyways to secure the disc brake rotor and the wheel hub together.

Abstract: The invention disclosed herein is an energy recovery system, for an electric motor, that uses the properties of dynamic braking to directly recharge a capacitive load made up of energy storage devices. The system contains switching circuitry that configures the energy storage devices into a capacitive load when braking is needed. Otherwise, the system configures the energy storage devices into a power supply for regular motor operation.

Abstract: The invention disclosed herein consists of an active electromechanical suspension and power generation system using an accelerometer connected to a controller. The electromechanical suspension consists of a geared motor and spring, which are used to isolate the vehicle chassis from the wheel, with the motor also functioning as a generator. The controller uses a 3-axis accelerometer's data to determine which direction to turn the motor and when to turn it.

Abstract: The invention disclosed herein is a hub-less vehicle wheel consisting of a rolling brace (14) inside a spoke-less wheel rim (12) and a two-layered solid tire (10). The outer layer of the solid tire (11) being design for contact with a vehicle road and for protecting the softer inner layer (19) with both Layers being firmly attached to the rim (12). The rolling brace (14) being designed as a support structure that attaches to a standard vehicle suspension while also negating any arbitrary forces to the tire (10).

Abstract: The invention disclosed herein consists of a hub-less vehicle wheel having a spoke-less wheel rim (12) and a two-layered solid tire (10). The solid outer layer of the tire has a treaded outer surface (11) bonded to and spanning from one side of the rim to the other, thus encasing the softer inner layer (19). The softer inner layer (19) is firmly attached to the rim (12) thereby indirectly binding the treaded upper layer (11) to the rim (12).
