Who in the realm of individuals remains unaware of the prominent American entity, Allison Transmission, established back in 1915? Spanning its extensive chronicle, the corporation has delved into realms such as motorsport and aviation. Presently, it stands as one of the globe's premier producers of automatic transmissions tailored for commercial vehicles. A surplus of 300 eminent Original Equipment Manufacturers (OEMs), specializing in buses, utility vehicles, firefighting apparatus, construction machinery, military conveyances, and various other vehicles, relies on the prowess of Allison's automatic transmission. Noteworthy is the fact that Allison Transmission was a subsidiary of General Motors from 1929 to 2007. However, in 2012, it metamorphosed into an independent publicly traded entity known as Allison Transmission Holdings Inc.
At the Szentgotthard plant, three distinct series of gearboxes find their culmination: the 3000 series, the 4000 series, and the Torqmatic. These transmissions, meticulously crafted, cater to a broad spectrum of commercial vehicles, ranging from long-haul trucks to construction behemoths, firefighting apparatus, utility vehicles, and other specialized automotive applications. The 3000 series caters to medium-duty vehicles featuring engines with a power output of up to 336 kW and torque levels reaching 1695 Nm. In contrast, the 4000 series is designed for heavy-duty machines equipped with engines boasting power up to 597 kW and a torque rating of up to 2644 Nm.
The gearbox configurations for both series encompass 6 or 7 gears, inclusive of overdrive and a secondary reverse. The transmission ranges are adaptable, tailored to the unique requisites of diverse technical applications. Additionally, all these gearboxes can be endowed with up to two power take-off shafts, accompanied by a retarder brake.
A hallmark of these transmissions is the cutting-edge 5th generation electronic control system, augmented by FuelSense technology. This innovative system not only enhances fuel efficiency but also offers adaptive capabilities to meet specific operational conditions. The FuelSense Package incorporates features such as an acceleration control system, a high-precision inclinometer for measuring road slope angles, EcoCal shift technology for maintaining optimal engine speed, Dynamic Shift Sensing for low engine speed gear shifts, and the Neutral at Stop option that lightens the engine load during halts, contributing to fuel economy and emission reduction.
Furthermore, FuelSense encompasses a smart control function that monitors power take-off (PTO) engagement, mitigating potential damage risks to components. Another notable feature inhibits gear engagement during the operation of specialized equipment until outriggers are retracted, cranes return to transport positioning, and doors are securely closed. The diagnostic function ensures timely maintenance alerts, averting premature oil and filter changes.
In essence, Allison's autom atic transmissions, adorned with these sophisticated design elements, demonstrate unparalleled efficiency across an array of machinery and operating conditions. These transmissions, especially those from Allison, provide a tangible solution to the scarcity of qualified drivers. The automated system inherently ensures seamless operation of engine and transmission components, thereby extending their service life. Moreover, Allison transmissions are programmable to impose speed and power limitations, such as during the truck's break-in period or to forestall traffic infractions, adding an extra layer of control and customization to meet diverse operational demands.
