Description:FIELD OF THE DISCLOSURE
[0001] This invention generally relates to a field of vehicle suspension systems, and in particular, to a leaf spring for a vehicle.

BACKGROUND
[0002] The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
[0003] Leaf springs are essential components of suspension systems in many commercial vehicles, providing necessary support, shock absorption, and stability. Over time, traditional leaf springs, typically designed with a rectangular cross-section, can wear out or suffer from fatigue due to the constant stress and l , Claims:We Claim:
1. A leaf spring for a vehicle, comprising:
a plurality of leaves, wherein each leaf (100) of the plurality of leaves having:
an elongated body (102) configured to be mounted to a vehicle chassis, wherein the elongated body (102) comprising:
a first end (104),
a second end (106), and
a central portion (108) disposed between the first end (104) and the second end (106) and configured to elongate or compress under a load,
wherein the elongated body (102) comprises a sinusoidal cross-section profile (110) to increase structural rigidity and load-bearing capacity of the leaf spring.

2. The leaf spring as claimed in claim 1, wherein the plurality of leaves of the leaf spring are progressively shorter in length and are configured to be vertically stacked together.

3. The leaf spring as claimed in claim 1, wherein the sinusoidal cross-section profile (110) comprises one or more crests (112) and one or more troughs (114).

4. The leaf spring as claimed in claim 3, wherein the one or more crests (112) an
