Autonomous Delivery of Improved Traction Capability
PROBLEM
“Drivers are frustrated by frequent incidents of poor traction and a sense of instability during turns.”
SOLUTION
Spicer® Trac-Lok® limited-slip differentials deliver improved vehicle handling by limiting wheel-slip rather than fully locking, and automatic traction engagement helps boost driver productivity.
The new Spicer® Trac-Lok® limited-slip differential for S110, S111, S130 and S140 medium-duty truck drive axle applications provides improved traction, autonomously. This design innovation from Dana delivers improved productivity and vehicle handling within a lightweight, compact design.
For the most demanding applications, Dana also offers the option of a locking differential for Spicer S140 axles that delivers full-locking, maximum traction.†
Limits wheel-slip for improved maneuverability
Spicer Trac-Lok benefits:
Boosts productivity
- Automatic traction engagement with no driver intervention
- Smooth operation
Longer lifespan
- Superior lifetime torque bias performance
- No degradation
Seamless upgrade
- No wiring or pneumatic connections
- Retrofittable with existing S110, S111, S130 and S140 axles
- No special lubricants or friction modifiers required
Optimized handling
- Operates with gear separation forces when there are differences in wheel torques
- Torque bias of ~3:1 in a slip event
Enhanced function
- Limits wheel-slip rather than fully locking, for improved vehicle maneuverability
- Freely differentiates in normal operating mode
- Available locking differential† for Spicer S140 axles delivers full 100% torque and power to both drive wheels
