Suspension is the mechanism that connects a vehicle to its wheels and permits relative motion between them. It consists of tires, tire air, springs, shock absorbers, and linkages. Suspension systems must support both roads holding and handling as well as ride quality, which are incompatible. Suspension adjustment is all about achieving the correct balance. Because all of the road or ground forces acting on the vehicle pass via the tires’ contact patches, it is critical for the suspension to maintain the road wheel in touch with the road surface as much as possible. The suspension also protects the vehicle from damage and wear, as well as any cargo or luggage. A car’s front and rear suspension may be designed differently.

The platform swing on iron chains connected to the wheeled frame of the carriage was an early method of suspension on ox-drawn carts. Although the iron chains were replaced by leather straps called thorough braces by the 17th century, this system remained the foundation for most suspension systems until the beginning of the 19th century. The thorough brace suspension system has never been utilized in a modern car.

Leaf springs first appeared on specific types of carriages around 1750, such as the Landau.

Elliptical springs may also begin to be utilized in carriages by the mid-nineteenth century.

Automobiles started as self-propelled versions of horse-drawn vehicles. On the other hand, horse-drawn vehicles were built for modest speeds, and their suspension was not well adapted to the greater speeds that the internal combustion engine allowed.

The first workable spring suspension needed sophisticated metallurgical knowledge and expertise, and it was only feasible with the onset of industrialization that it became possible. Obadiah Elliott was the first to file a patent for a spring-suspension vehicle; each wheel had two strong steel leaf springs on each side, and the carriage’s body was connected directly to the axles by the springs. Most British horse carriages were fitted with springs within a decade, with wooden springs in light one-horse vehicles to evade taxation and steel springs in bigger vehicles. These were generally made of low-carbon steel and came in the shape of multi-layer leaf springs.

Leaf springs have been used since the time of the ancient Egyptians. To power their siege engines, ancient military engineers utilized leaf springs in the shape of bows, which had little effectiveness at first. Years later, the usage of leaf springs in catapults was improved and made to operate. Springs were not always constructed of metal; a strong tree branch, such as one used in a bow, may also be used as a spring. This technique was utilized in horse-drawn carriages and the Ford Model T, and it is still employed in bigger cars today, mostly in the rear suspension.
