ABSTRACT:
A suspension system for vehicles. With some vehicles, both tractor units and fixed lorries, no separate suspension is provided for the drivers cab. This can cause considerable discomfort to the driver, and changed legislation is such that with, e.g., agricultural tractors, they are not permitted on public highways unless the cab is suspended. It is desirable to provide an effective cab suspension system, an objective met by a construction including a front suspension unit, a rear suspension unit, an attachment of the front of the cab to the front suspension unit, and an attachment of the rear of the cab to the rear suspension unit, at least one of the attachments to the front and the rear of the cab being pivotal and at least one attachment being positioned at a height that is the approximate mid-height of the cab.
