The H6620 heavy-duty transmission and the 4000 Series 6-speed and 7-speed transmissions exhibited by Allison Transmission at the International Construction Machinery Exhibition held in Las Vegas on March 22, 2011, for their outstanding performance, Outstanding efficiency and productivity have attracted the attention of the construction industry. Allison's gearboxes for mining, non-road construction and heavy-duty transport provide a feasible matching solution for OEMs and end-users. Visitors took the opportunity to discuss in depth how to install and use the vehicle according to the requirements of users. Allison transmission.
Allison Transmission is a world-renowned supplier of fully automatic gearboxes and hybrid systems for commercial vehicles. In this exhibition, Allison also introduced a series of cases used in the medium-sized machinery field: In Australia, a mining train equipped with Allison transmission can transport iron ore weighing more than 500 tons at one time; In Sweden, a corporate customer engaged in heavy-duty transport has designated the Volvo FH16 to be fitted with Allison transmissions to meet its extremely high load capacity requirements; in the Swiss Alps, the AstraHD8s equipped with Allison transmissions successfully completed the high-altitude cable of the hydropower station. task. In the United States, three traction tractors rely on the extraordinary power transmission performance of the Allison transmission to complete the haulage of a nearly 800,000-pound transformer.
"Our automatic transmissions offer extended torque range, greater vehicle loads and higher production efficiency, which are very important for construction teams," said Lawrence, International Marketing Executive Director of Allison, "Allison automatically The gearbox can achieve uninterrupted power shift, this seamless full-power conversion is very smooth, Allison transmission can fully use the engine's horsepower, and through the unique vehicle transmission system integration program to better these powers The application, which is Allison's 'extreme optimization', allows Allison's customers to achieve the best combination of vehicle performance, fuel economy and productivity. Allison's trucks can achieve higher The average speed, but also can reduce the powertrain failure, reduce operating costs and increase production efficiency and benefits." Lawrence said.
In addition to the 4000 Series and H6620 gearboxes that appeared at the show, Allison's complete gearboxes from the 1000 series to the 9000 series were able to complete the daunting and complex tasks in the mining and construction sectors. The Allison products, the smallest power 1000 series can be used for heavy pickup, 3000 series can be matched with 425 horsepower 1,695 Nm engine and installed on medium-sized construction vehicles and cranes. The 5000, 8000 and 9000 Series are Allison's largest commercial transmissions and, like the 6000 Series on display, are suitable for fixed and mobile off-highway equipment; the 9000 Series can be equipped with up to 2,250 hp and 8,270 Nm of torque. Engine.
The Allison 4000 Series also offers options for assembling drive pumps to match the emergency steering systems required for most European 8x4 dump trucks. In addition, the Allison 4700 and 4800 Series seven-speed gearboxes also provide a "second reverse gear," a pattern known as "deep reverse," which provides the vehicle with better control and Engine braking capability on steep grades and better handling in limited space.
This series of gearboxes also enhances the functionality of electronic control systems, with load-based shift programs (LBSS) and pre-diagnosis functions. The LBSS system can automatically select dynamic, economical and super-economic shift programs based on the slope of the slope of the actual vehicle load and run-time operation. Although specific energy consumption varies according to operating conditions and driver operating conditions, LBSS has been proven to improve fuel economy by up to 5% under the same conditions.
Allison's pre-diagnosis function can judge and prompt when the transmission needs maintenance. Data including oil level, oil life, filter life, and transmission working status are monitored in real time by this function. This eliminates the need for owners to replace the gearbox oil and filter cartridges, which not only saves maintenance costs, but also minimizes maintenance downtime on the premise of maximum protection of the gearbox.
In response to changes in engine characteristics of construction-specific equipment, Allison recently introduced models 5620 and 6620. The two products can better utilize the new engine electronic control system, more accurately calculate the power required by the drive train and deliver more accurate torque accordingly, so as to better protect the drive system.
Thanks to design, manufacturing, and material upgrades, advanced processes such as latching clutches, turboshafts, turbine hubs, and flywheels further reduce maintenance costs and reduce downtime for maintenance. At the same time, the gearbox software is constantly being upgraded.
Enhancing the performance of products is only the first step for smart operators. They rely on Allison’s expanding global service network and professional and well-trained maintenance personnel to ensure the maximum operational efficiency of vehicles.
