Car PWD Transmission
Introduction
A car PWD transmission, also known as a powertrain with differential, is a type of transmission that uses a differential to split the power from the engine between the two driving wheels. This allows the wheels to rotate at different speeds, which is necessary when the car is turning. PWD transmissions are typically used in cars that have a rear-wheel drive layout.
How a PWD Transmission Works
A PWD transmission consists of the following components:
- A driveshaft
- A differential
- Two axle shafts
The driveshaft connects the transmission to the differential. The differential is a gear assembly that allows the two axle shafts to rotate at different speeds. The axle shafts connect the differential to the wheels.
When the car is driving in a straight line, the differential sends equal amounts of power to both wheels. This causes the wheels to rotate at the same speed.
When the car is turning, the differential allows the inside wheel to rotate more slowly than the outside wheel. This is necessary because the inside wheel has to travel a shorter distance than the outside wheel.
Advantages of a PWD Transmission
There are several advantages to using a PWD transmission:
- It allows the wheels to rotate at different speeds, which is necessary when the car is turning.
- It provides better traction in slippery conditions.
- It can improve fuel economy.
Disadvantages of a PWD Transmission
There are also some disadvantages to using a PWD transmission:
- It is more expensive to manufacture than a FWD transmission.
- It is heavier than a FWD transmission.
- It can be more difficult to maintain than a FWD transmission.
Conclusion
PWD transmissions are a good option for cars that need to be able to turn and handle well. However, they are more expensive and more difficult to maintain than FWD transmissions.
