Adam]In today's program joining us here are Meltem Darakci and Erik Pigmans. Hi there! They are going to tell us more about the conditions the drivers and buses operate in and how fully automatic transmissions, electric hybridand electric axles can make the difference. Later on, wewill talk with [person name] from VanHool,a company specialized in premium coach busesandRik and Janfrom “Alk Travel Creators”, a company specialized in creating personalized unique travel experiences.We will then switch to a team from Isuzu bus who will share some driver experiencesthey had with buses equipped with an Allison. Last but not least, we will close with a “gigantic” story from Astvaldur Oskarsson organizing extremeglacier expeditions in a “monster”bus. So an exciting program, let's get started!
[Erik]Sure. You cancompare it a bit with a hovercraft flying smoothly overthe water. A hoovercraft has one or two big “fans” which pushair to the opposite direction. By moving the air, the hovercraft can accelerate very fast atcontinues speed without shocks.In essense the torque converter in a fully automatic transmission works based on this same fan principle.Like you can see on this 3D model on the tableand the image in the background, the torque converter consists of two fans, sitting opposite of each other. Instead of blowing air the fan will push fluid to the other fanwhich starts moving. The pump fan is connected to the engine and the other fan, which we call a turbine, is connected through the transmission to the wheels. There is a smaller fan called "stator"in between these fans which pushes the fluid around for a second push against the turbine wheel and that ensures the torque and power is multiplied by two at standstill.
[Adam]OK right, so I assume this will allow for fast acceleration than?
Adam]So with a fully automic transmission you will have a comfortable ride, minimizing the risk of spilling coffee on someone or mistyping on theirlaptop!
[Erik]Exactly, you got it!
[Meltem]Allison is currently in the market with an electric hybrid propulsion systemcalled eGen Flex, as well as a full portfolio of electric axles, the eGen Powerfamily. Since not one product fits all we have different solutions depending on the situation. Take for example a Coach or Tour bus, which often commutes long distances between cities and then has to drop off passengers in the city center. Today the battery technology will not provide sufficient range to run on a battery the full day. This is where our eGen Flex hybrid can come in which can flexibly run on diesel for the long distance and then switch to full electric mode when entering a city and driving without any emissions.
Adam]Can you maybe explain more how an e-axle works? I can imagine me as a laymen and the people watching need some help here to understand.
Adam]Wow, what a fascinating solution and what a nice piece of engineering. I can imagine you will need a lot of power to get a coach bus fully loaded with travelersand heavy luggage moving!?
[Meltem]You are absolutely right. The e-axle familycan handle heavy duty commercial vehicles and ranges from 10t rear axle load up to 13t. As you can see here on the 3D model, the e-axle has two very powerful electric motors, each achieving over 240kW continuous and a peak power of more then 320kW. With two of these motors in our axle, we're able to put down more power than a Lamborghini Aventador -so heavy loaded coach buses as you indicate powered by our e-axles will really be able to accelerate! In addition, we combine this with a 2 speed gearbox which enables uncompromised performance for low speed gradeability and high top end speed. Imagine a fully loaded coach trying to get uphill on some of these zigzag roads inthe mountains of Switzerland, France or Spain...
[Adam] Yes I can imagine. What a power you need! And amazing to hearthese solutions are already available now. Thank you so much Meltem!
[Rik]Hi Adam, I am Rik Gaens. Together with my brother Geert, we run “Alk Reismakers” or in English “Alk Travel Creators”. It is our passion to create and organize memorable and tailor made trips for companies, associations, clubs and private individuals. Whether it’sfor an inspirational tour in China with 40 super market managers or a travel safely to Paris with 130 final-year school students for two days, we develop a trip travelers not forget.
[Jan]Hi, I am Jan Willemsand I have been a bus & coach driver with Alk Reizen for more than xyz years. I recently started counting, and over the years I must have driven more than 999.999 kilometers mostly across Europe
[Adam]Wow that’s impressive. So it is an understatement you have quite some experience driving those buses. Can you maybe share with us what Allison fully automatics brough to you?
Adam]So I imagine that everyone drove an Allison in your team?!
[Jan]
I remember one day I was sitting in the canteen and heard some colleagues already arguing “who was going to drive the Allison bus” in the next shift.
[Adam]Well that for sure tells there is something magic about having an automatic on board!With all those years of experience, do you maybe have an interesting story to share?
[Adam]Thanks for sharing this story Jan. So Rik, what does fully automatics bring to you as a fleet ownerof Alk Travel Creators?
[Adam]OK so your total cost per mile go down. Is there anything else which will bring the cost down?
[Rik]Well what is also helping to reduce wear and tear of the service breaks is the retarder. Through the fully hydraulic retarder on the transmissions you can slow down by simply releasing the throttle. This saves use of the servicebreaks, especially when you drive down the hill! Retarder is a great solution I would recommend anyone with a bus!
[Adam]Now that we have learned more about the bus application and the technology, let’s hear from some persons who experienced driving in some busesequipped with fully automatics.Yesterday, I was able to interview some visitors atAllison’s Experience Center in Hungary whodid a ride & drive.Let’s see what they have to say!
[Adam]
Hello Murat,thank you for taking the time to talk to us during this ride & drive event and welcome to the show!I understand you work for Anadolu Isuzu. Can you maybe short introduce yourself and your company?
[Adam]And now let's continue our journey exploring some of these extreme vehicles. Let’s movefrom the warm and sunny Johannesburg to the freezing cold Icelandwhere we spoke with Astvaldur Oskarsson about some of the coolest buses I have seen in my life!
