vehicle designed to carry two to six passengers and
a limited amount of cargo, as contrasted with a truck
, which is designed primarily for the transportation
of goods and is constructed with larger and heavier
parts, or a bus (or omnibus or coach), which is a
large public conveyance designed to carry a large
number of passengers and sometimes additionally small
amounts of cargo. truck is constructed on the general
lines of the automobile but uses larger and heavier
parts.
It may be powered by a gasoline internal-combustion
engine or a diesel engine. In some trucks propulsion
is supplied through a single front or rear axle, in
others through two rear axles, and in still others
through both front and rear axles. Many trucks have
automatic or semiautomatic transmissions. Smaller
trucks are built as a single unit, but larger trucks
are frequently combinations of a truck tractor, which
contains an engine, transmission, and cab, and a semitrailer,
which is a trailer that the tractor hauls. |
