ACP RXT-G iii - BackTracker Electronic Steering






RXT-G ACP BackTracker Steering system
Updated: 2012.03

===

The LongRanger III is equipped with ACPropulsion's
BackTracker steering system.
This system is  designed to keep the trailer directly behind
the tow vehicle whether the vehicle is moving forward or backward.
The trailer hitch and ball each hold sensors that
determine the  trailer’s angle to the vehicle. The wheels also hold
sensors that determine the trailer’s speed and direction
(forward or reverse).  Between these systems a PCB controls the
directional inputs to a servo motor which adjusts the wheel
pitch based on those inputs.  There is no  software
involved in the system.

The following pictures show examples of each of the components of the BackTracker steering system

Pots to refine and adjust the steering system

The hitch ball. Note the machining that accommodates the ball sensor in the four (4) pictures to follow

Note the two (2) lag bolts and lock nuts under the 2x2" receiver. We added these to eliminate all motion from the hitch coupling system. This ensures that the hitch & ball remain rigid to the vehicles frame at all times. With this modification the trailer is perfectly quiet behind the vehicle and the steering geometry reads the precise angle of the trailer.

Note the Blue cover on the hitch assembly. It houses the corresponding coil sensor that reads the hitch angle from the balls angle.

Here are the wheel sensors. This is the method of reporting speed and direction back to the PCB

The following set of pictures show the rack and pinion (worm gear) assembly. This assembly also holds the gearing system

The servo motor has a white support rim where a colar mounts to ensure water tight operations

This is the interior of the servo motor gear housing

The rack and pinion worm gear / ball bearing system are shown here. This takes lateral pressure off the servo motor and allows smooth controlled operations.

The next two pictures show the BackTracker steering in operation. Note, as the front wheels of the vehicle turn, the BackTracker steering corrects the trailer to remain directly behind the vehicle.
