BAE Systems and Caterpillar Inc. have signed a long-term supply agreement to collaborate on an energy efficient parallel hybrid propulsion system for heavy-duty trucks. Under the 20-year agreement, BAE Systems will integrate the Cat CX family of transmissions into its HybriDrive parallel propulsion system, and will establish an aftermarket field services model leveraging Caterpillar's vast global service network to support the growing installed base.
The parallel system - the latest member of BAE Systems' HybriDrive family - complements and draws upon the company's proven HybriDrive series system, currently deployed in more than 3,800 transit buses across the globe. The system, which can improve fuel economy by an average of 30 percent, is designed for heavy-duty truck applications that include refuse collection, construction, pick-up and delivery, and utility vehicles.
The long-term supply agreement helps to ensure a consistent supply of transmissions from Caterpillar; long-term production pricing schedule; a warranty agreement; and a field service support model designed to make use of Caterpillar's well-established global network.
The Cat CX family of transmissions delivers reliable performance, rugged durability, fuel economy and Cat product support necessary for on- and off-highway applications. Caterpillar designs and manufactures integrated powertrain systems that maximize vehicles' versatility and transmission performance.
The HybriDrive parallel system will integrate with "big-bore" and heavy-duty diesel engines. The system is suitable for vehicles from 19,500 to 80,000 lbs. total gross vehicle weight. The parallel system will deliver significant environmental benefits by lowering emissions, reducing fuel consumption and lowering noise pollution in the field.
Recent field tests in spring 2011 revealed that trucks powered by the HybriDrive parallel system experienced an average fuel economy improvement of 30 percent when compared to diesel engine trucks. While the fuel ratings were experienced across a range of standard driving cycles, the system performed best on stop-and-go cycles where average speed is between five and 20 miles per hour, making it an optimal choice for refuse collection and delivery trucks. Based on duty cycles and fuel usage, a truck fleet owner who uses the HybriDrive parallel system can expect payback within three to five years.
The HybriDrive parallel system is in final stages of development and is expected to be deployed in markets around the world early in 2013.
For more attend Electric Vehicles Land Sea Air USA 2012 ,where uniquely we reflect the new realities that there are now six key enabling technologies and they are competing in all forms of EV, hybrid, pure electric and land, water and airborne, manned and unmanned. Speakers from ten countries detail the situation in their parts of the world including SYNPER 3 from Singapore, first to fly an electric helicopter recently, showing how up to 35% of helicopter crashes could be avoided with hybrid electric technology. Sun Yat-Sen University China and Germany Trade & Invest detail their national situations. Next generation batteries are covered by Robert Bosch (Bosch Group) of Germany, Oxis Energy UK, IBM USA and others. OLEV Technologies will show how to continuously pick up power, Schneider Electric of France how modern charging infrastructure is a system not boxes. There will be two presentations on supercapacitor breakthroughs - here is the future. See the full picture, with best-in-class speakers from across the whole world - Slovenia to Gibraltar, China to Canada, each carefully chosen by IDTechEx because of their leadership. There are two presentations on agricultural EVs and five on electric aircraft including Boeing and Airbus involvement. Other presenters include BMW (cars etc), Mitsubishi Motors (small commercial vehicles and cars), Daimler AG (commercial and military vehicles and cars) and Toyota (leader in electric forklifts, electric cars and buses but also presenting on its fuel cell vehicle program.) Uniquely, a large number of electric vehicle manufacturers not seen in conventional EV events will present including iRobot Corporation Autonomous Underwater Vehicles AUVs (better known for EVs as robot vacuum cleaners). Mission Motors and two others focus on electric motor cycles. Many manufacturers of industrial, commercial, military, cars and other EVs will be there. Come to this event where you avoid the usual speakers with nothing new to say and meet people new and useful to you without doing a lot of travelling to find them. Apply for an award.
