What are the advantages of a hybrid quad for Defence compared to a normal one?
It reduces noise, requires less fuel and is also sustainable. “Good story!”, thought Rob Verbuggen and Mattijs Tweehuysen and together they founded Reeq (Range Extended Electrical Quad) to carry out the development and construction. The result is a hybrid quad with a special and exceptionally efficient drivetrain. Apex Dynamics was allowed to make a small contribution to this special project.
Gearbox in power steering transmission
Various tests have shown that the hybrid quad performs well, also in terms of comfort and ease of use, but Verbruggen has a number of other wishes. For example, they want to further improve the transmission of the power steering.
In a power steering, a worm gear transmission is normally used. A torque sensor is then used to provide feedback to the engine and determine how much torque is needed. The difference with a normal car is that the steering wheel can turn 3 times (1,080 degrees) and with a quad only 90°. You therefore need much more torque to still be able to make a full steering movement.
In the last iteration, a low-backlash AB090 Gearbox from Apex Dynamics (with custom motor adapter plate) now for the desired result. The worm gear box has been replaced with a planetary gear box and the 50:1 ratio provides sufficient torque for the power steering and therefore the quad to keep manageable and precisely steerable.
