Retroline’s auto-sensing, anti-jackknife trailer

Date:18 September 2012 Tags:, ,

Using basic Meccano models to visualise his design, John Abel worked out the fundamental flaw in conventional trailer hitches: the articulation point is located between the towing vehicle’s rear wheels and the trailer’s wheels. When reversing, this means the trailer gets pushed from behind its wheels, so it turns in the opposite direction to the towing vehicle.

Abel reasoned that temporarily locking this articulation point in place when necessary would stop the trailer contra-articulating while being pushed in reverse. Instead, it would follow the same path as the towing vehicle. Another benefit would be no jackknifing under hard braking. Towing would be much safer and stress-free.
