Abstract: A suspension system (400) for supporting a chassis (200) of a vehicle (100). The suspension system (400) comprises a suspension unit (442). The suspension unit (442) comprises a wheel arm assembly (444) comprising a first wheel arm (402) having a chassis mount end (410) and a wheel mount end (412). The chassis mount end (410) of the first wheel arm (402) are provided with a chassis mounting member (414), the chassis mount end (410) of the first wheel arm (402) and chassis mounting member (414) being pivotable relative to one another around a chassis mount pivoting axis (230). The chassis mounting member (414) is configured to support the chassis mount end (410) of the first wheel arm (402) so that the first wheel arm (402) and chassis mounting member (414) are operable to pivot 180 degrees relative to one another about the chassis mount pivoting axis (230).

Abstract: A noise-reducing device for a vehicle wheel rim comprises two elements arranged to secure the device around the wheel rim. The elements are arranged to form a closed loop that is a close fit with the wheel rim so that the device is self-retaining on the wheel rim. At least one cavity is formed in one of the elements, the cavity having an opening to provide communication between the cavity and the tyre cavity. The cavity is arranged to define at least in part a chamber that acts as a Helmholtz resonator when the device is installed onto the wheel rim.

Abstract: A vehicle frame in which the transversal beams are linked to the longitudinal rails by means of a plurality of clamps joined by a high efficiency adherent substance.
