Infinite Counter Balance

Request Number N673786
Need details

IncWell's partner is looking for a method to make a infinite counter balance to assist with lift gate mass variation.




The rear door on CUVs and SUVs with power lift gates utilize either a roof mounted actuation system or a power strut system to open and close the lift gate. With lift gates that have a single sided drive system, a counter balance strut is required on the opposite side to balance the gate and prevent twisting. These struts aid with gate opening and closing efforts.  


There is a need for an infinite counter balance which can be slightly tunable in order to allow for different build variations on a vehicle assembly line. For example, a lift gate with and without speakers changes the center of gravity of the gate and may create the need for 2 different counter balance part numbers. Current gas struts only help to ensure the gate stays open and pops up slightly during initial release from the closed position.


Key Success Criteria
  • Lift gate to remain in full open position when opened.  
  • Gate to pop open from fully closed position when handle is activated. 
  • Target $15 per system
  • Minimum TRL 2
