Infinitely Variable Steering Transmissions

BPTi personnel each have decades of engineering experience with combat vehicle powertrain design and development with military vehicle programs such as the Bradley Fighting Vehicle since its inception in the 1970's which hosts the Infinitely Variable, Hydromechanical HMPT 500-3 (600hp) transmission.  BPTi's objective has been to support the next generation (e.g. GCV) of military fighting vehicle and to that end has conceived many different versions of mechanical as well as hybrid electric transmissions suitable for a broad range of applications.  BPTi's latest patent pending design, with a vehicle objective of 40-50 tons and 800-1000 horsepower, is a  HMPT500 based design with double the performance of that transmission.  The design can be hydromechanical or parallel hybrid and as a key feature uses proven HMPT500 components and systems as a low risk, cost effective, high reliability design approach. 

Parallel Hybrid Electric Truck Transmission

An aggressive 7 month development program from design to prototype build for a medium size Class 4/5 delivery truck.
Patented, Multi-range, continuously variable (CVT) transmission capable of reducing fuel consumption and emissions by over 50%.           "with regard to the power flow, this transmission is a rather ingenious device . They (BPTi) obviously know their way around transmission design". --- Ricardo Transmission

Series Hybrid Bus Transmission

Designed and developed a high-speed (>15,000rpm input) planetary gearbox as part of a commercial, hybrid electric series drive for a city bus application.  To date BPTi has produced prototypes and over 3100 production gearboxes .
