ABSTRACT:
A steering stabilizer and quick coupling assembly for a multi-trailer combination or train consists of a tractor, a towing or lead trailer, a steerable dolly and a rear or towed trailer. The assembly minimizes the oscillatory yaw and rollover tendency between the towed trailer and its steerable dolly. It also provides for quick coupling or uncoupling between the lead or towing trailer and the towed trailer. Further, it prevents off-tracking steering misalignment between the lead trailer and the steerable dolly. The assembly is mounted between the lead and rear trailers, and has as its basic components, a drawbar member and coupler assembly which are pivotally coupled and uncoupled at a vertical pivot on the drawbar member. The drawbar member and coupler assembly are each pivotally connected to a respective trailer frame portion for movement only about a transverse horizontal axis, and the vertical pivot is preferably located substantially midway between the transverse horizontal pivot axes. The vertical pivot may be fixed to the drawbar member or mounted for limited universal pivoting relative to the drawbar member. The coupler assembly includes spaced apart coupler members which are connected together at one end to a common support and unconnected at their opposite ends thereby permitting the drawbar member to be sandwiched therebetween for coupling.
