Multi-combination vehicle incorporating an electronically coupled power trailer

摘要

A multi-combination vehicle or road-train consisting of a powered prime mover, at least one powered trailer and which may include a number of non-powered trailers. The power trailer includes a cooling means (92) separated from the engine to provide improved cooling and enabling the road-train to be used in confined areas such as in underground mines. Typically the cooling means (92) are located at the front or rear of the power trailer. The engines of the prime mover and power trailer(s) are controlled either by a synchronisation system and a dual-pot accelerator pedal by controlling their relative torques or by manual controls in the truck cab.
