John D Zalewski

John D Zalewski, a reputed inventor hailing from Liverpool, NY (US), has made significant contributions to the field of power transmission devices for four-wheel drive vehicles. With an impressive portfolio of 26 patents, Zalewski has demonstrated his expertise in developing innovative solutions.

One of his latest patents is for a "Compact transfer case with beveloid gearset." This power transmission device is specially designed for four-wheel drive vehicles and includes an input shaft connected to the power source. It features a first output shaft that transmits torque to the first driveline and a second output shaft that transmits torque to the second driveline. Notably, these output shafts rotate along non-parallel axes. The transfer unit comprises a cylindrically-shaped gear and a conically-shaped gear that are in constant meshed engagement, bringing efficiency and improved performance to the power transmission system.

Another notable invention by John D Zalewski is a "Traction control system for 4WD/AWD vehicles." This method controls the powertrain of vehicles, directing power from the engine and transmission to all four wheels, only the front wheels, or only the rear wheels. By monitoring information transmitted over a communications network, the system determines whether various powertrain components are in an active or inactive condition. This determination is crucial in optimizing the power distribution and ensuring seamless performance. Importantly, the system autonomously switches these components between the active and inactive conditions based solely on information from the communications network, eliminating the need for user intervention.

During his career, Zalewski has worked with renowned companies such as Other and New Venture Gear, Inc. These collaborations have allowed him to further refine his inventions and contribute towards advancements in the automotive industry. Notably, he has worked with esteemed colleagues like James S Brissenden and Aaron Ronk, fostering a collaborative environment where breakthrough ideas flourish.

The groundbreaking work and numerous patents of John D Zalewski showcase his expertise in the field of power transmission devices and traction control systems for four-wheel drive vehicles. His inventions have undoubtedly made a significant impact within the industry, enhancing vehicle performance, efficiency, and safety.
