What are the layout schemes of automobile transmission system?

Hello, according to the position of the engine relative to each assembly, the automobile transmission system has the following arrangements:

1) Front engine rear wheel drive (FR): Front engine rear wheel drive.

Features: Traditional layout, adopted by most trucks, some cars and buses.

2) Front engine front wheel drive (FF): Front engine front wheel drive.

Features: It is a gradually popular layout form in cars, which has the advantages of compact structure, reduced body weight, reduced floor height and improved handling stability at high speed.

3) Mid-engine rear wheel drive (MR).

Features: it is the layout adopted by most sports cars and formula racing cars at present.

4) Engine rear wheel drive (RR): Rear engine rear wheel drive.

Features: At present, the general layout of large and medium-sized buses has the advantages of reducing indoor noise and being beneficial to the internal layout of the car body.

5) All-wheel drive (nWD)4-wheel drive

Features: There are multiple drive axles, and a transfer case is added behind the transmission, which is used to transfer the power output by the transmission to all drive axles through several sets of universal transmission devices, and can further reduce the speed and increase the torque. I hope I can help you and adopt it. Thank you.
