Patent ID: 10525817

Abstract:
A supplemental transmission assembly including a dual-clutch assembly, a first supplemental input shaft, a second supplemental input shaft, and two independent sets of gears. The supplemental transmission assembly couples to the primary vehicle transmission, receiving rotational energy from the primary transmission output shaft of the primary vehicle transmission. By including a plurality of gears in two independent sets, the supplemental transmission assembly allows the vehicle to smoothly progress through the gears when accelerating or decelerating, providing smooth operation and the maximum fuel efficiency for the vehicle. In addition, the supplemental transmission assembly limits the load on the engine by limiting engine RPMs to less than approximately 2500 RPMs via a computer-controlled engine management system, while progressing through gears quickly and efficiently. Accordingly, the supplemental transmission assembly improves engine and fuel efficiency by providing an intermediary assembly between the primary vehicle transmission and the drive wheels.
