OF THE CAR |  |
The car consists of units, mechanisms
and the systems forming following parts: the chassis, a body, the
engine. Chassis include transmission, a running gear and management
mechanisms. Transmission serves for transfer of a twisting moment
from the engine to wheels of leading bridges, changing a twisting
moment on size and a direction. Transmission consists of coupling,
a transmission, the transfers, one or several leading bridges. The
mechanism which allows quickly and to connect or separate smoothly
the engine with transmission mechanisms, coupling is. The transmission
is a mechanism which will transform a twisting moment transferred
from the engine through coupling, on size and a direction. The transmission
gives the chance to the car to move forward allows to disconnect
the engine from leading bridges for long time, back. Kardannaja
transfer gives the chance to transfer a twisting moment from a transmission
to leading bridges under changing corners depending on roughnesses
of a road covering. The leading bridge includes the main transfer
and differential with semiaxes. The main transfer will transform
a twisting moment on size and transfers it from transfers through
differential to semiaxes of driving wheels under a constant corner.
The differential is the mechanism which allows to rotate to driving
wheels with various speed under the relation to each other depending
on degree of their coupling with a road covering.

The frame, forward and back axes, springs, shock-absorbers, wheels,
tyres enter into a running gear. Management mechanisms include a
steering and brake systems. They allow to change a direction and
speed of movement, to stop the car and to keep it on a place. Modern
cars have bearing body to which all units and mechanisms fasten.
The bus body represents salon in which passengers take place. The
lorry body consists of a cabin of the driver and a platform for
cargo placing. To a body carry wings, facing, a cowl and mudguards.
The engine is the unit which will transform thermal energy received
at combustion of fuel in cylinders, in mechanical work, and created
with the help krivoshipno-shatunnogo the mechanism the twisting
moment uses for car movement.
