Thule Chariot Trailer Hanger Bracket Security
Description
Hi all, I've redesigned the Thule chariot trailer hanger for a number of reasons. 1. The original hanger would be obstructed by the kick stand. 2. The bolt, nut, or quick release can be undone and the trailer stolen. 3. The hanger comes loose over time even when the bolt is tightly fasened. My design hopefully improves upon the original in some ways. If you decide to use this design then its at your own discretion. I will take no responsibility for its failure. I have taken precautions in the design such as reinforcing certain areas and printing it in Prusa PCblend at 100% infill. I also tend to print slightly hotter to help with layer bonding. You will need an M8 allen key bolt and a suitable axle. I use the quick release axle from Cube Acid which was designed for their specific trailers attached to a Cube Stereo Hybrid 160 eMTB. When the trailer hitch is installed it covers the bolt so it cannot be stolen. The ball hitch is centered with the axle to reduce twisting forces which could loosen the bolt. The front part has been thickened to resist the ball hitch from pulling out of the bracket. The lock that secures the hitch can be used but the lock can be placed above which makes it easier to lock/unlock. The back section has been extended to help prevent the locking post from pulling through the material. The bolt should sit at the perfect level so not to interfere with the ball hitch. The ball hitch is slightly behind the bolt so that the inner shoulder has no interference. There is a flat section on one side to indicate which side the lock should attach. I have attached the original solidworks part file and an .stl file for printing. I apoligise for the rushed text but all the information regarding the design should be there. Currently, I am testing the bracket with my Thule Sport 2 Chariot fully loaded and so far it seems to work just fine. Hopefully you it will serve you well also but please let me know if you have any issues or require any modifications. Kind regards, Tim
