Detroit Optimized Powertrain

Having all mechanical and electronic powertrain development ‘in-house’ is a

significant competitive advantage

What is an ‘Optimized Powertrain’?

• Matching the final drive ratio to the efficiency characteristics of the engine

• Lower cruise rpm equals better efficiency . . . but compromises performance leading to increases in the frequency of shifts

• Driveline mechanical efficiency must be maximized to realize engine efficiency benefits of reduced rpm operation

What is needed to create an Optimized Powertrain?

• To overcome performance issues and shift frequency – AMT

• To maximize mechanical efficiency - Direct Drive Transmission + friction optimized axles

Why do we need vertical integration?

• Maximizing fuel efficiency while meeting today's performance and reliability expectations requires integration of engine combustion hardware and calibration, transmission ratio and shift strategy, correct axle ratio and smart electronic controls

Daimler Trucks

Optimized Powertrain: AMT as a Missing Link

Fuel Economy

Automated Manual Transmissions (AMT) The “brain” behind a proprietary

and optimized powertrain with the ultimate goal to improve fuel economy.

• More gears and shorter shift steps to keep engine in sweet spot

• Direct drive without maneuverability or startability compromises

• Improve Engine Downspeed: Unique engine ratings and axle ratios

• Best gear shift management

• Advanced features such as Eco-Roll

• Reduction in aftertreatment regen cycles

• Powertrain damage protection

A highly integrated powertrain and a control strategy optimized to

manage fuel economy couldn’t be realized with a manual

transmission.

Current Research and Development – More than an Idea

• Detroit Team dedicated to Powertrain Optimization

• Computer Simulations and Analysis

• Reliability and Durability testing of optimized component configurations

Which Customers Should Spec Which Axles?

Front: mid rated 12k to 14.7k

Rear: low rated tandem 34k – 40k

Fast ratios (<3.42)

Depending on load weight, a Cascadia will

favor fuel economy with low ratios and

weight. The front must be mid rated to

support a large engine.

Front: high rated 16k to 20k

Rear: high rated 44k to 46k tandem

Tall ratios (4.78+)

With front mounted equipment and a bed

full of salt, a snowplow would require high

ratings. To transmit high torque for low

speed driving, tall ratios are favored.

Pusher or tag axles may also be needed.

Front: low rated 6k to 10k

Rear: low rated single 13k – 20k

Medium ratios (3.58)

With lower weight, lighter axles are favored

to increase payload. The single rear

provides maneuverability and ratios

depending on urban or highway delivery

routes.


Rear: high rated single 17.5k – 40k

Tall ratios (4.11)

Mounted equipment requires high weight

ratings front and rear; with tall ratios for

low speed, high torque driving.

Front: mid rated 12k to 14.7k

Rear: mid / high rated 40k to 46k tandem

Medium ratios (3.58)

Similar to long haul but with heavier loads,

bulk haulers may require higher rated rear

axles with higher ratios


Rear: high rated tandem 44k to 46k

Tall ratios (4.78+)

Construction vehicles need the strongest

axles to carry the load. Tall ratios are also

required for low speed, high torque

driving. Pusher or tag axles may also be

needed.

ROLL vs. RUB

Bushing Needle Bearing

Needle Bearings Advantages: Tighter tolerances produce less tire wear, less maintenance and

greater reliability

Daimler Trucks

Turning Radius Advantages: Maximum maneuverability, wheel cut, and turning radius

Daimler Trucks

Friction and Thrust Bearings Advantages: Optimized resistance and balance of road input to the steering wheel,

steering feel, steering „returnability‟ and tracking.

Friction bearing (LH)/Thrust bearing (RH)

Detroit Single Rear Axles

Daimler Trucks

How it works:

Our ring and pinion gears do not need to be “paired”, the

machining process is so precise that you can match any

pinion with any ring gear and they will mesh perfectly.

Precision Cut Gears Advantages: Consistent gear mesh for quieter operation

The ring gear and pinion tooth profiles are precision

ground using a dry power cutting process followed by a

grinding process. This precision machining ensures a

consistent gear mesh resulting in more efficient power

transmission.

Daimler Trucks

Differentials Advantages: Robust, yet simplified design contribute to longer life and increased

torque capability

Pinion

Ring gear

Differential

Differential – internal components

• Larger differential due to elimination of head bearing

• One piece differential case – stiffer and more precise construction

• Ring gear creates the 2nd half of the differential case

• Less deflection, more precise mesh of the gears

Daimler Trucks

Detroit Tandem Rear Axles

Daimler Trucks

• Hypoid – pinion centerline is below the ring gear centerline

• Topoid® (Amboid) – pinion centerline is above the ring gear centerline

Hypoid Topoid / Amboid

Hypoid and Topoid (Amboid) Gearing Advantages: The near 0° driveline angle between each axle reduces

vibrations, increasing durability and driver comfort

Daimler Trucks

Inter-Axle Differential Advantages: Helical gears spin more freely and easily helping to avoid heat

build-up and damage from spin-out.

Use needle roller bearings and a thrust bearing.

Daimler Trucks

• For 40,000 lbs tandem axles,

we offer an intermediate track

Traditional Driver Communication

Detroit Virtual Technician eliminates the “mystery” as to why a light is on and

provides the fleet the ability to instruct the truck operator to take the

appropriate action to best deal with the issue

Daimler Trucks

What does Virtual Technician do for the Customer?

Service Event VT Action Customer Benefit

Service Soon Detroit CSC sends a notification, as well

as recommended service and contact

information for the Detroit Customer

Support Center (CSC)

Trucks continues to

operate and customer is

notified of recommended

action (and potential

assistance if needed)

Service Now Engine information automatically relayed

to the Detroit CSC for analysis. A

trained representative will evaluate the

data and recommend possible solutions.

If required, the CSC will provide listings

of the nearest service locations to the

customer, who makes the decision on

which location to seek service.

Customer contact (and

driver via contact) is

notified of recommended

action avoiding any

potential damage to engine

and providing quickest up

time solution.

Daimler Trucks

A CSC Remedy Ticket is created at the same time the customer is notified via email

that a fault has occurred. CSC agent will open the ticket and review the captured log

file. Then a follow up email is sent to the customer with parts and service info.

Detroit Diesel Customer Support Center

Daimler Trucks

Virtual Technician - Repair Facility Service Notice

Two Scenarios:

1) Customer selects repair facility for service event and notifies CSC

• CSC forwards service event details to repair location prior to visit

• Customer takes truck in for repair at the Dealer/Distributor

– Detroit will follow up with the repair location until the unit is released

• Repairs made and truck returned to service

2) Customer does not advise CSC of repair location for service

• VT customer shows up for repair at the Dealer/Distributor

… no work package.

• Repair facility can find the VT work

package on VT Registration web site by VIN

• If needed the Dealer/Distributor can

contact the CSC for any repair assistance

– If Detroit knows where the truck is, we will

follow up until the unit is ready for service

• Repairs made and truck returned to service

Daimler Trucks

Virtual Technician – Log File Review

• Having log file allowed CSC agent to

find voltage fault, not actually low

pressure caused code.

• A non VT unit would have resulted in

several hours spent on fuel system

to find fault.

• Likely replacement of several parts

without cause (NTF‟s)

Fault Code 157/16 Fuel Rail Pressure Low • Finding „Shorts/Opens‟ Immediately

vs. Long „NTF‟ Diagnostics

Subject: Virtual Technician Case Number738389

Virtual Technician has sent details of an important fault code on unit # 618923 (Customer Truck

Number), VIN – (Last 6) AN4082 to the Customer Support Center.

The code logged 100/1(SPN/FMI) indicates

"Engine Oil Pressure".

This code requires service now or a disruption en route may occur. To avoid severe

engine damage, DO NOT RUN THE ENGINE. Failure to address this code or using the engine

override button may result in severe engine damage. The engine override button should only be

used to drive the vehicle to a safe location where the engine can be turned off.
