What are the four major systems of a car chassis?

The four major systems on the chassis include the transmission system, running system, braking system, and steering system. Below is a detailed introduction about these four systems: Running system: The running system of a car mainly consists of wheels, suspension, and axles. Braking system:

As a veteran driver with decades of experience, the four major systems of a car's chassis include the drivetrain system, running gear system, steering system, and braking system. The drivetrain transmits engine power to the wheels, enabling the car to move. Common issues like transmission aging causing jerking require timely oil changes and maintenance. The running gear absorbs road bumps, consisting of the suspension and tires – if too stiff or soft, it affects stability, especially when driving unsteadily on rough roads. The steering system controls direction, linking the steering wheel to the front wheels; failure makes turning difficult and prone to accidents. The braking system is critical – failure has severe consequences. I believe these systems complement each other: slow power transmission means weak acceleration, weak braking means inability to stop. Monthly chassis inspections ensure safe driving with peace of mind.

I love modifying cars, and the four major chassis systems are the drivetrain, suspension, steering, and braking. The drivetrain manages power output, and upgrading it can enhance acceleration. The suspension is key to the handling system—stiffening it improves cornering grip. Responsive steering makes driving more thrilling, but improper modifications can lead to dangerous oversteer. Upgrading brake calipers in the braking system shortens stopping distances. I often neglect suspension maintenance when tuning cars—once, loose suspension caused excessive bouncing and nearly led to a loss of control. These systems are interconnected—while car modifications bring plenty of fun, basic maintenance shouldn’t be skipped, especially for brakes, which are critical to safety. Regular checks at professional shops help avoid major issues.

Over the years of driving, I've learned about the four major systems of a car chassis: the transmission system manages engine power delivery; the suspension system handles wheel support; the steering system controls direction; and the braking system manages stopping and deceleration. These systems must work in proper coordination for safe driving. Transmission issues result in weak acceleration; brake failure spells danger at high speeds; steering abnormalities lead to loss of control in turns. Regularly check brake pads and steering fluid—don't wait for strange noises before repairs. These systems safeguard driving safety and demand meticulous attention.
