The gear box -The gearbox is a set of gears used to force processing and transmission of rotational motion at different aggregates or vehicles. It is a component of the kinematic chain of transmission that allows broadening the range of speeds and times the impeller. Mounted usually between clutch and transmission longitudinally. On vehicles built after solution "all before" or "all covered" longitudinal transmission disappears, so that the gearbox is disposed between the clutch and transmission plant.



Six-speed transmission of the system fulfills a multiple vehicle: torque amplification and broadening the scope of the wheels driving speed over that provided by the engine's speed limits, and granting the possibility of reversing and kinematic chain interruption of transmission mechanism for parking the vehicle with the engine running long. Gearboxes are made by different levels of reports called transmission gears, engine energy grants opportunities to energy requirements of the vehicle in motion to ensure dynamic performance, fuel consumption and pollution as good.

The transmission
Overview  - Transmission system consists of parts and organs with specific roles as follows: clutch, gearbox, transmission Cardan, main transmission, differential, distributor reducers, planetary gear shafts final.
Clutch  - Coupled clutch gradually disengaged from the rest of the engine transmission, both at home and while walking, step change gearbox.

Gearbox  - Gearbox thrust or speed change depending on the amount Drag is made possible without reversing  the engine and also allows the car while parking lengthy engine operation.
Transmission cardans  - Cardan transmission, time passes engine to the transmission to the main gearbox. Its necessary due to the difference between the geometric axes of the trees, the difference caused by oscillations of the suspension system.

Differential  - Differential allows the driven wheels of the same deck, turning to cover different distances.
Trees planetary  - Trees planetary differential transmit the engine when the driving wheels.
Final transmission  - Final transmission ratio increases total transmitere.Există only some buses and large trucks.

Construction of a coil - The coil is made by winding a conductor (usually copper) on a core. This core may be ferromagnetic, in this case the coil with high inductance, or may be non-ferromagnetic, or even absent (as air core), in this case coil with low inductance. AC coil is of an inductive reactant, frequency dependent alternating current.

Physical aspects - Inductance (measured in henry, H) is a physical quantity equal to the ratio of magnetic flux established by a circuit current passing through it, and that current intensity. A change in current produces a magnetic flux variation, which in turn produces electric power that tries to oppose change in current.
