The new ECTED™   -  Welcome to the ECTED's new home on the web. This section will allow you to keep up to date on Auburn Gear's latest OEM Differential product!

ECTED 
Auburn Gear has developed an Electronically Controlled Traction Enhancing Differential – the ECTED™. The electronic activation feature allows the ECTED to be interactive with vehicle dynamic systems to provide optimum traction. It also does not require external pneumatic or hydraulic connections. The ECTED greatly enhances the traction required for severe off-road and towing applications such as pickup trucks and SUVs. It can also be integrated with ABS and traction-control systems to provide the enhanced traction required of luxury and sport performance vehicles. The ECTED’s compact design and variable torque transfer capability lends itself to many differential applications.  

The ECTED’s simplicity, ease of installation, high torque transfer capability, and other controllable features makes it an attractive cost-to-benefit design.

ECTED's Features and Benefits 
The ECTED is designed to be controlled by a vehicle’s on-board control system. Listed below are some of the performance capabilities when integrated into such a system:

Variable Torque Transfer Capability – The ECTED’s torque transfer is electronically controlled and is infinitely variable from essentially an open differential to that of 100% torque transfer. This allows the transfer of torque to be modulated to give the vehicle maximum traction without compromising vehicle stability.  

Automatic Engagement & Disengagement – The ECTED is "seamless" to the driver. When wheel slippage is sensed it instantly and automatically engages to the torque bias level required. Likewise, it automatically disengages immediately when torque transfer is not needed. Additionally, the friction-based clutches of the ECTED allow for smooth and quiet engagement and disengagement unlike "positive clutch" style differentials which are abrupt and noisy.  

Programmable to Anticipate Wheel Slip – Since the clutch actuation is electronic, the ECTED does not have to rely on wheel slip to be activated as with viscous-type and hydraulic designs. When controlled by a system that monitors throttle position, the ECTED can be engaged when a rapid increase in throttle position is sensed, indicating a desire for maximum acceleration and traction. In this situation, the ECTED engages in anticipation of the need for maximum traction.  

ABS & C-lock Compatible – Because the ECTED is electronically controlled and is capable of instantaneous disengagement, it can be deactivated at any point in time so as to not interfere with ABS systems. It is also designed to accept C-lock designed axle shafts.  

Programmable to Meet Vehicle Performance Requirements – When connected to a vehicle’s on-board control system and monitoring conditions such as wheel speeds, steering position, throttle position, yaw, etc., the ECTED can be controlled to meet a variety of vehicle performance requirements.  

Fits Into Most Existing Axle Housings – The ECTED has been developed in several sizes and has been designed to fit within many current OEM axles without modification except for a wire entrance hole.   

ECTED Don't just limit slip, control it!  In testing now, our Electronically Controlled Traction Enhancing Differential (the ECTED™) has the brains and brawn to get your vehicle to those places other differentials limit you from.

About AG Differentials 
The operating envelope for any traction enhancing differential is determined by the lines shown for an open differential (minimum torque bias) and a solid axle (maximum torque bias).   The intercept of the torque bias line is determined by the spring preload. The slope of the torque bias line is determined by the characteristics of the clutch design.   The effective operating envelope of a limited-slip differential ranges from 1.67:1 to 5.0:1 torque bias ratio.   Equation:  Torque Bias Ratio = (Tight Wheel Torque)/(Loose Wheel Torque) 

 

Differential Background 
How the Auburn Limited-Slip Differential Works
The highly efficient torque transfer capability of the Auburn Gear limited-slip differential is achieved through the use of cone clutches coupled to beveled side gears. As torque is transmitted through the differential side gears to the axle shafts, the side gear separating forces and spring pre-load firmly seat the cones into the differential case. The cone design, along with the applied force, determines the torque transfer capability of the differential. When torque levels decrease, as in a cornering maneuver the gear separating forces also decrease, allowing the axle shafts to rotate independently. All Auburn Gear limited-slip differentials are designed to provide the maximum amount of torque transfer without compromising the performance requirements of a vehicle in situations where torque transfer is not required.  

Features of the Auburn Limited-Slip Differential
The Auburn Gear limited-slip differential allows more power to be transferred to the high-traction wheel than is possible with other differentials. Along with greater power transfer capabilities, its design can be tailored to meet the specific performance requirements of your vehicular applications. In performance vehicles, features can be specified to enable high torque transfer during acceleration yet provide low resistance for cornering under normal driving conditions. In trucks and recreational vehicles, characteristics can be modified to provide high torque transfer for low traction start-up conditions.  

Applications
No matter what your application-performance or passenger cars, light duty trucks, vans, sport utility vehicles, off road, or recreational vehicles the Auburn Gear limited-slip differential can be engineered for your design requirements to provide smooth torque sensing operation with bias ratios to meet your performance needs.  

State-Of-The-Art Design and Test Lab
You get exactly what you specify -- faster and at a lower cost -- with Auburn Gear's CAE/CAD system, complete with Finite Element Analysis [FEA]. This system allows us to develop and optimize the differential design for your requirements.  

These designs are challenged in the real world with our prototype testing labs, where every aspect from metallurgical properties to mechanical performance is proven against the design parameters. Our axle dynamometer tests the differentials to prove the design under load conditions while computer-aided manufacturing systems produce components to individual design specifications.  

But testing is not confined to in-house labs alone. Our unique on-site testing capability brings engineers right into the field to prove the design of our limited-slip differentials under actual working conditions. Differentials are subjected to a variety of rigorous vehicle tests to assure you of getting the high performance reliability you need.

Located in the industrial heartland of America, Auburn Gear has the capability and capacity to meet increasing world market demands for traction-enhancing differentials-all while maintaining and improving every aspect of design, quality, delivery, and price which translates to total customer satisfaction for you.
