AUTOMATIC TRANSMISSION AND SEMI-AUTOMATIC TRANSMISSION

Mesin Automatic

Night Engineers, This evening I will explain the differences of Transmissions, in automatic transmission is a transmission that performs automatic gearshift acceleration. To change the speed of the automatic transmission system is used friction mechanism and automatic transmission oil pressure. In the automatic transmission planetary gears function to change the speed and torque as well as the gears in a manual transmission.

Tendency for people to use the automatic transmission has increased in recent years, especially for luxury cars, and even certain types are already fully automatic transmission. The same trend occurred also on a motorcycle like Yamaha Mio, Honda Vario.

Overhaul

Automatic transmission models:

Automatic transmission is controlled by simply moving the lever to the acceleration of certain positions. The position of the automatic transmission lever arranged to follow format PRND-3-2-L, as there are from left to right or from top to bottom. Machine can be turned on only at the position P or N only.

General mode of the automatic transmission are as follows:

P (Park) position to the vehicle is parked, transmission is locked in this position so that the vehicle can not be driven.
R (Reverse) is a position to reverse the vehicle.
N (Neutral) is the neutral gear position, engine ties with the wheels in the free state.
D (Drive) is the position to go forward under normal conditions.
2 / S (Second) is a position to move forward on mountainous terrain.
1 / L (Low) is a forward position on the gear to one, only used when driving on very steep terrain.

While optional is:

3 is a position to go forward and the transmission will not switch on the gear shift position.
O / D (Over Drive) is the position of the transmission gear shift that occurred at a higher engine speed.

SEMI-AUTOMATIC TRANSMISSIONS

Semi-automatic transmission is a transmission gearshift acceleration without stepping on / depress the clutch, the system uses electronic sensors, processors and actuators to move the gear acceleration on the order of the driver. This system was developed in anticipation of traffic congestion in urban areas. Semi-automatic transmission is also used on luxury sports cars such as used Porsche, Maserati, Ferrari is sometimes placed on the steering wheel to facilitate the acceleration of tooth movement.
another usage
Outstanding motorcycle in Indonesia in the early 1970s to the present generally use semi-automatic transmission is simple, moped very popular at that time only recently begun to be produced and marketed otomatisseperti transmission motors used on Yamaha Mio, Honda Vario.
