Construction
The PRG is driven by a DC brushed motor that delivers power to the PRG gear assembly. The
motor transfers mechanical power though a flexible metal drive shaft to a worm gear.
PRG Assembly PRG Motor And Drive Shaft
The metal drive shaft is wire wound to increase strength. A spiral wound fiber thread surrounds
the drive shaft to ensure the clearance between engagement points is minimum.
Drive Shaft Drive Shaft And Worm Gear
The drive shaft transfers power from the motor rotor to the worm gear set of the PRG gear assembly.
The final gear ratio provides the strength and speed needed to open and close the rear gate.
