In the last article, we had discussedClassification of IC Engines and Components of IC Engines whereas, in Today's session, we will discuss on Types of Chassis in Automobile based on fitting of the engine, No. of wheels fitted in the vehicle, No. of driving wheels and also on the type of drive (Front Wheel Drive, Rear Wheel Drive, and All-wheel Drive), etc. in a detailed way.
Let's dive into the Topic.
Classification or Types of Chassis:
The classification of chassis is based on:
According to the fitting of the engine
According to No. of wheels fitted & No. of driving wheels
According to the Drive
The explanation for types of chassis is as follows:
1. According to the fitting of engine:
Engine at back
Engine at the centre
Location of Engine: Outside the driver cabin
For Example Cars, Mahindra Jeeps, etc.
For example TATA SE Series of Vehicles
Location of Engine: Totally in the driver's cabin
For example Buses, Trucks, etc.
Engine at back:
Location of Engine: At the back portion of chassis
For example Leyland Buses (Volvo Bus)
Engine at centre:
Location of Engine: Center of the chassis
For example, Top Speed cars like Porsche, Renault Alpine, etc.
2. According to No. of wheels fitted & No. of driving wheels:
3. According to Drive:
Rear Wheel Drive
Front Wheel Drive
All Wheel Drive
Left hand Drive
Right hand Drive
Lets discuss more on Rear Wheel Drive and Front Wheel Drive.
Rear Wheel Drive (RWD):
Engine Power is transmitted to the rear wheels via the gear box, propeller shaft, differential and axles whereas the Front wheels are used for providing the direction for the motion of the vehicle.
Traditionally, Vehicles are of Rear wheel drive only and now it is moving towards Front Wheel Drive.
Advantages of Rear Wheel Drive:
Mileage: In general, Rear-Wheel drive vehicle gets less mileage than FWD.
Complexity: It is less complex than FWD
Ruggedness:Much higher than FWD.
Handling:RWD is better because the front wheels are just to turn the vehicle whereas the power will be given only to the Rear wheels
