DESC:TECHNICAL FIELD
[001] The embodiments herein generally relate to chassis in vehicles and more particularly, but not exclusively to a modular chassis and an apparatus and a method for manufacturing modular chassis in vehicles.

BACKGROUND
[002] Generally, a load carrying vehicle is a type of vehicle which has a cargo carrier mounted on a chassis behind a cabin to transport goods. There are various types of cargos built to support the goods transportation depending upon customer requirements. Loading capacity is the primary requirement of the load carrying vehicle. The loading capacity includes pay load and overload capacities of the cargo carried by the cargo carrier. Pay load gives the maximum permissible load allowed by manufacturer to carry goods in service for the overall vehicle to remain intact for its complete life cycle. Over load capacity is the capacity at which the vehicle can bare the maximum load (more than pay load) and it is the main design load at which the vehicle get designed and verified. Original Equipment Manufacturers (OEM) decided the over load value which may be around 60% of pay load which is the maximum loading capacity. Further, kerb weight of the vehicle, means the vehicle weight without occupant and goods plus pay load becomes the GVW (Gross Vehicle Weight). The overall GVW decides the category of the vehicle. Hence, while designing chassis & cargo carrier, payload and overload capacity of vehicle is referred to first.
[003] The length, width and height of cargo carrier are crucial in terms of overall vehicle size and the cargo carrier dimensions are defined by the payload and overload capacity of the vehicle. The specific length of vehicle determines the type of that particular vehicle and all legal, central motor vehicle rules (CMVR), and taxation regulations apply to that vehicle. Hence, the length of cargo carrier needs to be considered while deciding the overall length of the vehicle. It is applicable for width also. These factors are different for various countries.
[004] Generally, length of the chassis is dependent on the length of the cargo carrier. The chassis length defines the wheel base of the vehicle. The chassis holds/supports, suspension system, engine system, cooling system, electrical systems, air intake system, cargo mountings and spare wheel mounting.
[005] Currently different variants of chassis for accommodating corresponding cargo carrier (various cargo carrier dimensions) with different pay loads are not available in the load carrying vehicle.
[006] Further, conventional systems and methods for manufacturing various chassis dimensions is difficult and is one of the challenges faced by the original equipment manufacturers (OEM). Furthermore, the aforementioned systems and method for manufacturing various chassis dimensions incur high manufacturing cost, higher rejection rate and higher number of operations for manufacturing the various chassis dimensions which thereby increases an overall manufacturing time and the process becomes tedious.
[007] Therefore, there exists a need for a modular chassis and an apparatus and a method for manufacturing modular chassis for a vehicle, which obviates the aforementioned drawbacks.

[008] The principle object of an embodiment of this invention is to provide a modular chassis for accommodating various cargo carrier dimensions.
