Amphibious vehicle

a technology for amphibious vehicles and vehicles, applied in the field of amphibious vehicles, can solve the problems of adversely affecting the safe operation of vehicles, becoming increasingly difficult and uneconomical to do, and increasing the obsoleteness of vehicles, so as to prevent heat dissipation of radiators, increase the cooling efficiency of radiators, and reduce the effect of engine cooling

AI Technical Summary

Benefits of technology

This configuration enhances the vehicle's buoyancy reserve while maintaining safety and reducing the risk of overheating, allowing for compliance with regulatory standards and improved operational efficiency in both water and land environments.

Problems solved by technology

However these vehicles are becoming increasingly obsolete due to outdated technologies.
While many operators continue their attempts to modify the original DUKW design, it is becoming increasingly difficult and uneconomical to do so while complying with the essential regulatory standards for operation.
In particular, it has been a great challenge to upgrade the existing DUKW design to meet the United Kingdom regulations for buoyancy reserve (i.e. 110% buoyancy) without adversely impacting on the safe operation of the vehicle.
In practice these methods have proven to be deficient in a number of ways.
For example in one case an attempt to meet buoyancy reserve regulations by packing foam into the hull of a DUKW was insufficient with the consequence of the vehicle sinking in an accident, and in other case the proximity of foam to moving parts caused overheating and fire.

Abstract

An improved amphibious vehicle comprising: a drive train; a plurality of ground engaging wheels; a cooling system; a water propulsion system; and a hull which defines a passenger compartment, wherein the form / shape of the hull below the waterline is substantially defined by a plurality of buoyancy modules that are demountably mountable to the amphibious vehicle.

Description

CROSS REFERENCE[0001]This application is a continuation of U.S. Ser. No. 15 / 519,093, which was filed on Apr. 13, 2017, and was allowed on Oct. 3, 2018; U.S. Ser. No. 15 / 519,093 is a national phase application of International Application No. PCT / GB2015 / 053162, which was filed on Oct. 22, 2015, and which claims priority to GB Patent Application No. 1418813.0, filed on Oct. 22, 2014.[0002]The present invention relates to an amphibious vehicle and a propulsion and cooling system therefor, in particular to an improved amphibious vehicle particularly adapted for sightseeing services.BACKGROUND OF THE INVENTION[0003]Self propelled vehicles having ground engaging wheels and being capable of operation on both land and in water are well known in the art. Such vehicles are most often seen nowadays as sightseeing vehicles whereby vehicle passengers visit sights on land before the vehicle enters the water as part of the sightseeing experience. Many of these sightseeing amphibious vehicles are b...
