Types Of Chassis | How Many Are There ?| All Types Explained #AskIT- Aaj ke time mein Indian market mein kitne saare segments of passenger vehicles introduce ho chuke hain, although three major segment of passenger vehicles still remain the same jo hain Hatchback, Sedan and SUV.
Abb to cater the affordable and budget restricted category of buyers sab hee segment ke compact versions introduce ho chuke hain and SUV segment ka toh compact se aur bhi zyada compact segment nikala jaa chuka hain which is termed as sub-compact SUV which are under the 4 meter length barrier.
So yeh sab hee segments or categories of vehicles are based on different platforms and unn hee platforms ko bolte hain Chassis or different types of chassis. Toh exactly kya hota hain chassis and what’s the role and baaki sab kuch related to different types of chassis hum aapko bataenge so let’s begin with it.
Type Of Chassis | Hatchback, Sedan & SUV | All Types Explained #AsktIT-
Types Of Chassis | What Is A Chassis?-
Human body ka basic structure is based on the skeleton, basically skeleton acts like a frame for the human body. Toh similarly ek gaadi ka frame hota hain uski chassis, yahi frame gaadi ki overall strength define karta hain. Jitne bhi types ke forces gaadi experience karti hain woh saare forces gaadi ki chassis hee handle karti hain. Infact chassis sirf four wheelers mein hee use nahi ki jaati even in two-wheelers chassis utna hee importance hold karti hain.
Types of Chassis | What Role Does A Chassis Play?-
So jaisa ki hum ne aapko bataya chassis ek gaadi ka body frame hoti hain jo provide karti hain rigidity and stability to a vehicle. So technically speaking chassis handles total weight of the vehicle. Iss total weight mein included hain vehicle ke saare important components like engine, suspension etc. and the passenger load.
With all the passenger load jab bhi aapki car bad roads yah fir any undulations on the road ke upar se jaati hain then chassis hee poori car ko jodke rakhti hain intact and absorb karti hain saare stresses this includes normal braking, acceleration basically all movements jo ek car undergoes in real life conditions on the road.
Different Types Of Chassis-
Depending on the type of usage different types of chassis are designed jiss par different vehicles are made. For example ek SUV jiss chassis par based hoti hain thats way different than the chassis jiss par ek hatchback yah sedan is made. So lets discuss exactly kitne types of chassis are there:
1. Monocoque Chassis-
Monocoque is a French word which means single piece armour, so by the name shayad aapko thoda idea mil gaya hoga exactly what monocoque chassis is all about. To make it simple for you, Monocoque chassis manufacture hoti hain as a single unit. Iss chassis ko construct kiya jata hain as a shell, basically gaadi ke top to bottom tak Monocoque chassis is there as a single protection shield.
Advantages: Currently modern world cars ko develop kiya ja raha hain on Monocoque due its numerous advantages jaise ki:
- Monocoque chassis ko jaisa ki hum ne bataya develop kiya jata hain as a single unit so issi wajah se Monocoque provide karti hain better overall protection.
- Easy to manufacture for mass production cars: usually Monocoque chassis ko prefer kiya jata hain in the cases of cars jo manufacture hoti hain for masses.
- Easy maintenance: jab bhi kisi car ka accident hota hain and if the chassis gets all the impact then usko repair karna is not a difficult task for car manufacturers.
Disadvantages: Sabse major disadvantage Monocoque chassis ka hain that it is heavier in comparison to other chassis jisse overall car ka weight increases.
2. Ladder On Frame Chassis-
Ladder on frame chassis was specifically developed for vehicles jo normal roads par kam and off-road zyada chalti ho. Basically vehicles jo heavy duty activities like off-roading, towing, loading etc. performa karti hain unke liye Ladder on frame chassis is made. By the name itself aap samjh sakte hain that iss chassis ka design is ladder like in which two very heavy beams which are parallely placed and unko join karte hain from the middle shorter beams.
Ladder on fram chassis setup mein, chassis ke upar vehicle body place ki jaati hain. So now kabhi bhi aap koi SUV yaah utility vehicle ko dekhe toh you can imagine what it looks under its body.
Advantages: Almost every SUV jo real SUVs hoti hain not the compact ones are based on Ladder on frame chassis.
- It is best for rugged use.
- Ladder on frame chassis mein vehicle components can be better put together and fir unki maintenance is also not complex.
Disadvantages:
- Ladder on frame chassis par made vehicles mein sabse zyada body roll is experienced.
3. Backbone Chassis-
Real world mein kaafi rarely use hone waale chassis setup mein se yeh hain Backbone chassis, iss setup mein just like the human body ek backbone hoti hain major jo connect karti hain top and the bottom of the shockers. Backbone chassis abhi bhi kaafi reliable hain and big car manufacturers like Škoda abhi bhi apni premium sedans issi par develop karti hain.
Advantages:
- One of the biggest advantage of backbone chassis is that, yeh cover karke rakhti hain driveshaft ko jo gaadi ke centre se hoke guzarti hain jisse driveshaft remains safe.
- Backbone chassis ki overall rigidity is more as compared to ladder on frame chassis.
Disadvantages:
- Very expensive chassis setup
- Expensive to maintain
So guys yeh the kuch types of chassis jo aaj kal ke modern world mein use kiya jaate hain to develop cars, and there are many other setups also but most of them are used for special purpose vehicles like racing cars and very heavy duty off-roading.
