Embodiment Construction

[0059] Detailed description of the preferred embodiment

[0060] In the following description, the main inventive idea of ​​a variable stop device for the automatic maneuvering of a sub-chassis on a trailer will be described, first with a general description, then with reference to two specific Examples are described. Some scenarios are described next. A particularly preferred form of the sub-chassis is hereafter described, with independently steerable axle arrangements. The sub-chassis can be used with either embodiment of the variable stop arrangement. Finally, a novel solution will be described for attaching a trailer according to the invention to the "five box" of a tractor.

[0061] Figure 1 shows a schematic plan view of an articulated vehicle 1 of the "semi-trailer" type, with a tractor 2 and a trailer 3 pivotally interconnected at a pivot 4 so that the tractor and trailer can circle a The upright axis 5 is relatively rotated. Vehicles such as vehicle 1 are well kn...

Abstract

The invention provides a trailer for use as part of an articulated vehicle (15) with improved cornering characteristics. The trailer includes: a main chassis (18) connectable to a wheeled section (16) of the vehicle immediately ahead of the trailer so that the trailer is rotatable relative to the wheeled section (16) about a substantially upright first axis (19) in the main chassis (18); a sub-chassis (20) having ground-engaging wheels (21) mounted thereto, the sub-chassis (20) being connected to the main chassis (18) and pivotable about a substantially upright second axis (23) in the main chassis (18); and stop means arranged for limiting rotation of the sub-chassis (20) about the second axis (23) and away from a position of a longitudinal alignment with the main chassis (18). The stop means is movable responsively to relative rotation of the wheeled section (16) and the main chassis (18) about the first axis (19). In a preferred arrangement, some wheels on the sub-chassis (20) are steerable responsively to rotation of the sub-chassis (20) about the second axis (23).

Description

technical field [0001] The present invention relates to an articulated vehicle having a tractor, or trailer, and one or more trailers. Background of the invention [0002] A common vehicle in this category is the so-called "semi-trailer", which has a tractor and a single trailer, which is usually longer than the tractor. A trailer typically has one, two, or three non-steering axles near its rear end and a turntable at its front end that mates with a cooperating device (sometimes called a "five box") on the towing vehicle so that the trailer can be articulated about a substantially vertical axis on the tractor for steering purposes. [0003] A number of problems arise with this type of articulated vehicle. One of them is the issue of manipulation. For example, roads that are wide enough to make turns are required, and driver proficiency is high, as compared to shorter non-articulated vehicles, as fixed wheels on trailers often "off the rails", i.e. do not follow the towing...
