The term "chassis" is used to designate the complete car minus the body. The chassis therefore consists of the engine, power-transmission system, and suspension system all suitably attached to, or suspended from, a structurally independent frame. The most common independent. This work serves as a reference concerning the automotive chassis, i.e. everything that is inside a vehicle except the engine and the body. It is the result of a.

The combination of chassis and outer covering is sometimes called an enclosure. Firearms[ edit ] In firearms, the chassis is a bedding frame on long guns such as rifles to replace the traditionally wooden stockfor the purpose of better accurizing the gun.

The chassis is usually made from metallic material such as aluminium alloy due to the more superior stiffness and compressive strength of automotive chassis compared with wood or synthetic polymer, which are commonly used in conventional rifle stocks.


The chassis essentially functions as a more extensive pillar bedding, providing a metal-on-metal bearing surface for the that has reduced potential shifting under the stress of recoil. Model Based Definition Model Based Definition Improve communications and reduce rework by incorporating product and process information during chassis automotive chassis using comprehensive 3D annotation automotive chassis that enable you to pass this information to downstream applications.

Wheels and Tires The automobile wheel has progressed from the original wooden-rim-and-wire-spokes affair borrowed from the bicycle to the present all-steel safety wheel designed specifically for automotive applications.

Made of two steel stampings welded together, the modern wheel combines great strength automotive chassis relatively light weight. Most compact cars are equipped with inch-diameter wheels 33 cm ; all other American cars use either or inch wheels 36 or 38 cm.


Tires also have undergone some radical changes over the years. For example, pressure has dropped from the 65 pounds per square inch used in early tires to the 24 pounds per automotive chassis inch now commonly recommended for low-profile tires.

A Stronger, Lighter Automotive Chassis

The tubeless tire, introduced in and now standard equipment, has added considerably to automotive safety. Increasingly, automobile manufacturers are regarding automotive chassis tire as an integral part of the car and not just as an accessory that is fitted arbitrarily into an already completed design concept.

More attention is being paid to the skidding characteristics of tires, and the scientific designing of automotive chassis treads and casings is contributing importantly to both automobile handling and passenger safety. Tires claimed to be virtually punctureproof are available to the American motorist.

Some feature a separate inner chamber that assumes the load if the regular tire casing loses its air; others utilize a gummy substance stored inside the tire to seal off leaks. In tire construction, the term "ply" automotive chassis to one of the layers of rubber-impregnated cords that provide a tire casing with automotive chassis and strength.

Thus a 4-ply tire has four layers of cord beneath its rubber tread face. By increasing the diameter of the tire cords, engineers have been able to design a 2-ply tire introduced in with the performance and safety characteristics of a conventional 4-ply tire.

In addition, the 2-ply tires provide a softer, more comfortable automotive chassis.


Once popular as a tire cord material, cotton has now been largely replaced by synthetic fabrics, such as nylon and rayon. Cotton deteriorates when moisture leaks through small cracks in the sidewall rubber and is therefore less desirable than the synthetic materials. Steering Gear Through a suitable mechanism and connecting linkage, the steering gear permits the driver to control the vehicle's direction of travel by simultaneously changing the angle of both front wheels.

Rotary motion applied to the steering automotive chassis rim is transferred via a steel shaft to a lubricant-filled steering mechanism bolted to the frame of the vehicle.
