OPENING

The power transfer system can also be called a power train system, a mechanism that transfers power from engine to wheel.

Front engine rear drive (front engine rear drive).

CONTENT

Power transfer system contained in the machine is divided into several parts, namely:

1.      Clutch

The coupling is located between the engine and the transmission. It functions to connect and disconnect from the engine to the transmission.
From the above description to maximize the clutch function, the clutch must be able to meet the following requirements:
A. The clutch must be able to connect the engine with the transmission gently.
B. The clutch must be able to free the connection from the transmission perfectly and quickly.
C. When connecting to a transmission, the clutch must be able to move power without slip.

2.      Transmission

Serves as a regulator of the size of the engine power output in accordance with travel conditions. Transmission is used to convert the engine power into a moment in accordance with the conditions of travel or when the vehicle must run backwards.
There are two types of transmission used in the vehicle that is manual transmission and automatic transmission. Manual transmission manages the amount of power out to the wheels using transmission gears.

3.      Propeller shafts

Propeller shaft on the rear drive vehicle serves to channel the power output from the transmission to the differential. Propeller shafts are of two types (Toyota Astra Motor 1995):

A.    2-joint type propeller shaft, propeller using only u-joint at both ends of the propeller.

B.     3-joint type propeller shaft, propeller using u-joint at both ends of propeller and there is center bearing in center propeller.
Univesal joint or u-joint is used to damp angle change to smooth the transfer of power from transmission to differential. U-joints are of two types:

C.     U-joint type solid bearing cup

D.    U-joint shell bearing cup type

4.      Differential

Differential serves to move and split the power to the wheels when walking straight or when turning. Differential is divided into two parts namely the final gear and differential gear that serves as follows (Toyota Astra Motor, 1995):
A. Final gear, function to enlarge the incoming moment in differential. The final gear consists of a pinion drive and a ring gear. The final gear has two types:
B. Differential gear, serves to produce different rotation speed of wheel when the vehicle change direction. Differential gear consists of differential pinion and side gear associated with axle.

CLOSING

From the material above can be concluded that the power transfer system there are 4 components that is coupling, transmission, propeller shaft, and differential
