AI Technical Summary

Technical Problem

Existing vehicle sets, such as those with hitch systems using balls, hooks, or saddle mechanisms, face challenges in stability and maneuverability due to complex motorization control, uncertain bicycle behavior when coupled with trailers, and increased longitudinal size.

Method used

A set of rolling vehicles comprising a front vehicle and a rear vehicle, connected by a coupling system with an orientation device that aligns the wheels of both vehicles, allowing for reduced longitudinal size and improved maneuverability.

Benefits of technology

The solution enhances driving stability and maneuverability by aligning the wheels of both vehicles, reducing the risk of the bicycle becoming entangled with the trailer, and minimizing the longitudinal size of the vehicle set.

Abstract

The invention relates to a vehicle assembly comprising a front vehicle (2), a rear vehicle (3) having, at the front of the rear vehicle, a yaw-axis steering device (35) to which is attached a front rolling axle system (31) of the rear vehicle (3), and a coupling system (4) such that, in the coupling configuration of the coupling system and on a horizontal flat surface, the wheel(s) of the front rolling axle system (31) of the rear vehicle (3) and the wheel(s) of the rear rolling axle system (23) of the front vehicle (2) are, in a top view of the vehicle assembly, aligned along their axis of rotation (A230, A310). Said axes of rotation pass under the chassis of the rear vehicle. Figure for the abstract: Fig. 18
