After reading in the “M-To” article V. Sedov, “the Trailer for “Jupiter” I thought that the exchange of experiences, ideas and technical solutions encourages and facilitates the work of Amateur designers. Perhaps my thoughts and study will interest readers, come across them on new interesting solutions or at least will help in the technical work.
Throughout the literature I found, almost everywhere, the traditional solution to the layout of the trailer for both car and motorcycle: with a symmetrical location of a node of the coupler relative to the longitudinal axis of the trailer. Design of motorcycle with a sidecar is clearly asymmetric, and the back of the stroller allows you to place the hitch symmetrically with respect to the track, unable to endure it beyond the envelope of the stroller.
Motor-fans come easy — they slip the coupling in the direction of the motorcycle, reducing the force turning the vehicle to the side of the stroller, and facilitates the working conditions of the tractor. However, the track does not coincide with the track of the trailer. In other words, each wheel its pads, which creates increased resistance to motion and complicates driving on dirt roads. Exploiting this trailer, which is shown in the figure, was convinced that to go around obstacles, ride on a dirt road, grader, and especially in the mud with him is very difficult. In addition, the offset of the trailer to the left creates a subjective feeling that he was in favour of the dimensions of a motorcycle; it’s always alarming when passing with oncoming traffic on narrow roads and curves to the right. In addition, for normal operation it is desirable to have a trailer with a soft suspension and minimal weight with a large enough capacity.
