Power Liftgate Drive Motor

To reliably open/close large and heavy automotive power liftgates with the push of a button, a highly engineered and optimized gear train was produced using unfilled POM and a highly filled PA 6/6 to replace powder-metal parts.  Innovations were required in gear body and rib design, optimization of the gear geometry, and mounting and application of precision bearings on the plastics shafts.  Not only was a 500% cost reduction achieved, but the gear train meets extreme thermal constraints and is highly tuned to NVH performance required by the customer.
