As the skeleton that holds all other components in place, your car’s chassis is its foundation.mechanical chassis Often overlooked in the build process, a well-designed chassis can make or break the performance, safety, and reliability of your hot rod. Learn about the different kinds of chassis and how they impact your vehicle’s overall structure, handling, and ride comfort.
In mechanical-engineering terms, the chassis is a structural framework that supports and transfers loads between major components—like the engine, transmission, wheels, axles, suspension, and payload—and the ground.mechanical chassis The chassis also determines the position, location, and layout of these major components. The chassis defines a vehicle’s overall strength, rigidity, weight distribution, and serviceability.
While the term “chassis” can refer to a number of different parts and components, it’s most commonly used to describe the frame or body of a motor vehicle.mechanical chassis While there are several different types of chassis, the two most common types of construction are ladder and backbone frames. Each type offers unique advantages and disadvantages for specific applications.
A pressed steel-based chassis formed the skeleton for most passenger cars through the middle of the 20th century.mechanical chassis This chassis, which was welded or bolted together, provided the mounts for the powertrain and other major mechanical components. A body was then flexibly mounted onto the frame, a process known as body-on-frame construction. This approach remains a popular option for trucks, which need to withstand the forces imposed on them when carrying heavy loads.
Tubular or space chassis, meanwhile, are the underpinnings of racing and high-performance cars.mechanical chassis This light but rigid design allows these vehicles to realise the highest levels of agility and speed. This form of chassis is also used in classic models like the Caterham 7, TVR Griffith, and other bespoke vehicles. A tubular chassis is lighter and more rigid than a ladder frame, but it’s not as good at handling lateral forces or bumps. Its complex and intricate design also makes it time-consuming to produce and expensive for mass production.
More recently, manufacturers have been utilising composite materials to improve the chassis’s strength and durability while reducing its overall weight.mechanical chassis These innovative materials offer impressive strength-to-weight ratios and have the potential to revolutionise the chassis industry in the future by allowing manufacturers to create highly complex custom components with minimal material waste.
Regardless of the material you choose for your chassis, it’s important to consider the quality of the components and how they’re sourced and assembled. Look for a manufacturer with a proven track record, extensive customer reviews, engineering documentation, proper warranties, and responsive customer support. In addition to selecting the right chassis for your project, regularly inspecting it for signs of wear and tear can help you spot any issues before they become worse.
As the driving experience evolves in the coming years, we’re seeing chassis innovations that are transforming how we use our cars. These new technologies are integrating mechanical tradition with virtual reality, artificial intelligence, robotics, laser processing, connectivity, and drive-by-wire systems to create cutting-edge automotive technology.
