BOGIE

ABogieas well as called Truck American is achassisor framework carrying wheels, attached to a vehicle, thus serving as amodular subassembly of wheels andaxles.

Bogies serve a number of purposes:

Support of the rail vehicle body.
Stability on both straight and curved track.
Ensuring ride comfort by absorbing vibration and minimizing the impact of centrifugal forces when the train runs on curves at high speed.
Minimizing generation of track irregularities and rail abrasion

Key components of a bogie include:

The bogie frame: This can be of inside frame type where the main frame and bearings are between the wheels, or (more commonly) of outside frame type where the main frame and bearings are outside the wheels.
Suspensionto absorb shocks between the bogie frame and the rail vehicle body: Common types arecoil springs, or rubber airbags.
At least onewheelset, composed of anaxlewithbearingsand awheelat each end
Axle box suspensions absorb shocks between the axle bearings and the bogie frame. The axle box suspension usually consists of a spring between the bogie frame and axle bearings to permit up-and-down movement, and sliders to prevent lateral movement. A more modern design uses solid rubber springs.
Brake equipment: Two main types are used:brake shoesthat are pressed against the tread of the wheel, anddisc brakesand pads.
In powered vehicles, some form oftransmission, usually electrically poweredtraction motorsor a hydraulically poweredtorque converter
