David S. Graziosi, president and CEO of Allison Transmission, said: "At this moment, it is exciting to be part of Allison as part of the industry. Compared to any time in the past decade, the entire industry The change is faster, and Allison is constantly introducing new initiatives."
Allison 9-speed automatic transmission
The Allison 9-speed gearbox has a depth-to-speed ratio and industry-leading speed ratio range. The efficient gearing enables the torque converter to lock up early in one gear, resulting in significant fuel savings. In addition, the 9-speed transmission is available with an integrated engine start-stop system that provides instant gearbox engagement and locks the output shaft when the engine is restarted, stabilizing the vehicle. The 9-speed transmission is used in a wide range of applications, providing ideal drive solutions for distribution vehicles, rental trucks and school buses.
Graziosi said: "With this new gearbox, Allison has once again demonstrated its commitment and commitment to fuel efficiency and vehicle emissions."
The Allison 9-speed transmission is built on the proven durability of the Allison 2000 Series 6-speed transmission, which has accumulated more than 100 billion miles in global vehicle applications. It has the same complete vehicle mating interface as the previous 6-speed gearbox and is designed to provide integration convenience for existing Allison 2000 Series vehicle manufacturers.
In addition, Allison has announced an expansion of its electric product range, including an electric hybrid system with a pure electric mode driven range of up to 15 kilometers, making it ideal for bus and coach applications. The system achieves zero emissions and provides a quieter and healthier environment when the engine is shut down during vehicle inbound, inter-station and outbound.
The system is also equipped with a high-energy lithium-ion battery to extend the cruising range when the engine is off; smaller and lighter dual inverters and water glycol cooling provide more efficient operation; further perfect mixing by adding Power Accessories II The system powers air conditioning, air compressors and power steering to improve fuel economy.
Graziosi said: "This hybrid system that extends the range of electric drive travel is based on one of the most reliable and efficient hybrid systems. Since 2003, buses using our hybrid systems worldwide have exceeded With 8,000 vehicles, Allison is a pioneer in the field of electrification and a trustworthy brand."
The hybrid system supports pure electric drive mode without the need for a charging facility. Battery charging is accomplished through brake energy recovery and engine operation. The brake energy recovery function extends the brake friction element replacement interval by up to 350%. The dual mode separation parallel structure improves fuel economy by up to 25%.
In addition to the Allison 9-speed gearbox and expanded motorized products, Allison continues to work with telematics service providers (TSPs) and OEMs to provide networking and support for existing and new users, enabling integration Efficient fleet management.
This networking feature is also compatible with the fourth generation of electronic control systems first introduced in 2005, providing more than 170 different gearbox status data. This will result in data collection and analysis for fleet management and maintenance personnel to improve vehicle uptime.
Allison will send gearbox health status information through multiple North American telematics providers by the end of the year. In addition, the development of more applications and the application of global regions are also planned.
