DESC:TECHNICAL FIELD
[001] The embodiments herein generally relate to brackets in vehicles and more particularly, but not exclusively to bracket assembly for connecting cabin to 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. The chassis is the supporting structure of the vehicle which is used for supporting the cabin, the cargo carrier and other components of the vehicle. The chassis of the vehicle has to be designed to withstand the forces and corresponding loads acting on it. Conventional vehicles comprise a L-shaped bracket for connecting the cabin to the chassis of the vehicle. The bracket is arranged in-line with respect to the cabin and the chassis long member, where a vertical portion of the bracket is connected in-line to the cabin and a horizontal portion of the bracket is connected in-line to the chassis long member. With the aforementioned configuration, the bracket is usually subjected to bending and torsional loads from the cabin due to direct contact of rear portion of cabin with the chassis long member thereby causing bracket failure. Further, the arrangement and method of connecting the cabin to the chassis in the aforementioned vehicles is subjected to bending of chassis long members at cabin-cargo interface during braking and acceleration which leads to collision of cargo front panel with cabin rear panel.
[003] Therefore, there exists a need for a bracket assembly and a method for connecting a cabin to a chassis of a vehicle, which obviates the aforementioned drawbacks.

OBJECTS
[004] The principal object of an embodiment of this invention is to provide a bracket assembly for connecting a cabin to a chassis of a vehicle, which withstands the force and corresponding loads acting thereon.
[005] Another object of an embodiment of this invention is to provide a method for connecting a cabin to a chassis of a vehicle.
[006] Yet another object of an embodiment of this invention is to provide a bracket assembly for a vehicle, which enables effective transfer of bending and torsional loads to a chassis of the vehicle.
