Apparatus and methods are provided to eliminate transient swaying of a towed vehicle imparted upon the towed vehicle during a towing operation by decoupling the towing and towed vehicles rotationally from each other. In one embodiment this is accomplished through the use of a doubly hinged tow bar and to steer the towed vehicle based upon the relative angular deflections of the two vehicles while subtracting out transient rotations of the towing vehicle.

The present invention comprises a weight distribution tag trailer, having at least some of the following features: (a) a frame assembly, including beams and cross beams and side axle beams, (b) an axle coupled to the frame assembly, (c) shims for optional position between an axle assembly and the side axle beams to allow adjustment of load and balance (d) at least two wheels rotatably mounted to the axle, wherein at least one beam includes an end complementarily sized to be received by a vehicle receiver hitch assembly, and at least one other beam includes a clamp for coupling the beam to a cross frame of the vehicle receiver hitch.

A modular slave vehicle articulatable at one end thereof to another slave vehicle and at another end thereof to an independently driven master vehicle, simultaneously. The slave vehicle comprising a body including a driving system; a structural frame supporting said body; a master coupling system in the form of a mechanical stress absorbing coupling mechanism; at least one first slave coupling device; at least one second slave coupling device; said first and second coupling devices, when mounted to two adjacent slave vehicles intended to be articulated to each other, are detachably connectable to each other to form a tandem coupling configured to constrain all DOF therebetween.

An articulated coupler permits vertical displacement of a towed vehicle relative to a towing vehicle while preventing lateral or horizontal displacement of the towed vehicle relative to the towing vehicle. Multiple linkage arms provide coupling for special configuration towed vehicles such as short wheel-mounted lifts that experience torsional forces due to the presence and absence of loads on the lift.

A steering system for a multi-car mass transit vehicle, the steering system providing a four-wheel Ackermann-type system for providing improved manoeuvrability of each car and bi-directional travel, with each car accurately following the path of the car in front when travelling in either a forward or backward direction. Alternatively, there is provided: an intermediate carriage for a multi-carriage vehicle, the intermediate carriage configured to connect to first and second carriages, and the intermediate carriage including a steering input and a steering output, such that the steering input is configured to accept a steering input from the first carriage, and the steering output is configured to provide a steering output to the second carriage. Further alternatively, there is provided a tyre-wheeled bogie arrangement for a vehicle, the bogie arrangement including a bogie body and at least one wheel including a tyre.
