A vehicle suspension comprises an assembly of a hub carrier and a support arm, the support arm being attached to the hub carrier at two points spaced from each other in the direction of travel and extending inwardly therefrom to a support arm attachment point for fixing to a chassis, and a trailing link extending from the assembly in a direction transverse to that of the support arm, toward a trailing link attachment point for fixing to the chassis. The trailing link preferably extends from the assembly in a forward direction, and is preferably connected directly to the hub carrier. A strut can extend upwardly toward an attachment point for fixing to a chassis, to provide a spring and damper. The support arm can comprise a pair of arms extending divergently from the attachment point to each of the two points. A toe control link extends generally parallel to but spaced from the rear arm, linking the hub carrier to the chassis to provide geometry control under high load conditions. The invention further relates to a vehicle, comprising a chassis and at least two wheels, one on each side of the vehicle, each wheel being attached to the chassis via such a suspension.

Current systems of distributing vehicles are inefficient, particularly in developing nations. To resolve this, we provide a kit for constructing a commercial vehicle supplied ex-works as a flat-pack package using the vehicle chassis as a pallet. Thus, the kit may include a chassis, an engine attachable to the chassis, located within and supported by the chassis, and a plurality of upright chassis members attachable to the chassis thereby to define at least a cabin, placed flat over the chassis. The elements making up the kit can be restrained in place, such as by wrapping or tying with suitable film, bands or cords. Body panels attachable to the chassis uprights can be supplied, placed flat over the chassis. Brake line, a wiring loom and major drivetrain items such as the engine, differential and propshaft may be pre-attached to the chassis in their final locations before shipping the kit. In this way, the complete kit can be prepared at a suitable factory and shipped as a flat-pack item. Very little packaging will be needed as the chassis itself can act as a pallet for the remaining items, providing the necessary rigid support to allow handling of the kit. The resulting item will have a footprint similar to that of the final vehicle, but a height which may be one third or one quarter. Together with suitable spacers, several such kits could be packed for transport in a single vehicle or container.

The support arm can comprise a pair of arms extending divergently from the attachment point to each of the two points. The hub carrier can include a pivot pin extending in a fore/aft alignment, passing through two pivot points on the support arm thereby to define the two points. The appropriate end of the pivot pin provides a convenient location for attaching the trailing link to the hub carrier. The invention further relates to a vehicle, comprising a chassis and at least two wheels, one on each side of the vehicle, each wheel being attached to the chassis via such a suspension.

We improve still further the crashworthiness of a tubular-frame chassis by providing a means for absorbing lower-energy impacts without deforming the tubular steel frame, The vehicle comprises a chassis structure including a load-bearing tubular chassis member extending longitudinally within the vehicle, at least one crush structure located laterally outside of the chassis member, the crush structure having an upper and a lower extent that overlap with an upper and lower extent of the chassis member. In this way, the crush structure is able to interact with the chassis member, transferring impact forces to the chassis member and thereby reducing the necessary size (and weight) of the crush structure. The crush structure is preferably removable, to allow replacement after an impact. Alternatively, the crush structure part of a door of the vehicle, positioned as necessary when the door is closed.

A chassis for a vehicle is disclosed which combines rigidity, speed of manufacture, and a small environmental footprint. Such a chassis (10) comprises a framework of interconnected tubular sections (14, 18) and at least one composite sheet (50) bonded to the framework, at least part (78) of the composite sheet comprising unidirectionally-arranged fibres, the part of the sheet and the unidirectional fibres extending obliquely rearwardly from one side of the chassis to another side. Laser cutting, CNC bending, and computer-controlled welding mean that the required production time can be kept to 120 seconds and the rigidity of the structure as a whole is sufficient. Such a chassis also has an exceptionally low carbon footprint. The sheet may comprise a plurality of sections, joined by a method allowing a positional tolerance so that any tolerance in the construction of the framework can be accommodated. The part of the sheet that is of unidirectional fibres extends obliquely rearwardly from a tubular section on one side of the chassis to another tubular section on the other side of the chassis, the fibres also being oriented obliquely rearwardly in the same sense. A further similar part (80) extends in the opposite direction, symmetrically, overlapping as necessary to form the sheet (50).

A vehicle seat (10) comprises a base unit (12) and an upright seat back (14), the base unit (12) being moulded composite materials with optimised fibre orientations and metallic fixing points for attachment to the vehicle and at least two laterally-spaced upstanding arms (46), the seat back (14) being of a moulded composite material with optimised uni-directional fibre orientations and being attached to each upstanding arm (46) via a connection that is distributed along the vertical direction. This vertical distribution can be achieved by providing a plurality of mechanical attachments (48) between the two parts, with the attachments (48) spaced apart in the vertical direction.

ELG Carbon Fibre Ltd and Gordon Murray Design Ltd have combined to create novel carbon fibre materials made from recycled carbon fibre waste that would have otherwise gone to landfill. These new materials are suitable for a whole range of applications which may include Aerospace, Military and Transportation as well as emerging markets that demonstrate a need for low cost carbon fibre reinforcements. Utilizing recycled carbon fibre in Gordon Murray Design’s patented iStream® process, for example, has created the opportunity for recycled carbon fibres to be introduced into mass production, low cost vehicle chassis structures.

Gordon Murray Designs innovative and ground breaking iStream automotive manufacturing technology allows significant reductions in setup, production costs, vehicle mass, and lifecycle CO2 emissions, whilst offering cost effective design flexibility that exceeds current Euro NCAP occupant and pedestrian impact regulations. The project consortium of Gordon Murray Design, Innoval Technology Limited, Constellium and Brunel University (BCAST) aim to develop an iStream monocoque that is 30 - 40% lighter than the incumbent steel/glass fibre composite structure. Using a novel high strength extrusion alloy combined with advanced composite panels based on recycled carbon fibre, the project aims to further reduce CO2 emissions through significant lightweighting, whilst maintaining the high volume, low cost benefits of the original disruptive iStream technology. The project also aims to take another major step, making full use of the iStream process, towards a new generation of lightweight vehicles for the UK market that can have a major impact on the UK government’s carbon reduction targets for the UK vehicle fleet
