Abstract
The need to save energy and, in particular, oil and gas fuels is currently an
acute global problem. Automobile transport is the most massive consumer of gas,
gasoline, and diesel fuel, which has led to the need to reduce their consumption
in some European countries by limiting the maximum speeds for cars. Reducing the
maximum speed of vehicles reduces energy and fuel consumption. Energy and fuel
consumption are proportional to the cube of the speed of the car. Reducing fuel
consumption when driving on expressways can be carried out without reducing the
maximum design speed of the car due to the rational design of the transmission
and the choice of engine power. This article presents the results of the
authors’ research implemented in new methods for designing car transmissions.
These methods are based on a more accurate determination of the aerodynamic
characteristics of vehicles, taking into account the change in the drag
coefficient depending on the speed. For example, for the ZAZ-1103 “Slavuta” car,
the actual air resistance at the speed of 145 km/h is six times less than the
calculated one obtained by the traditional method. The obtained results allow to
improve the quality of the design process and increase the energy efficiency of
cars.
