What is the rod connecting the wheels called?
3 Answers
The rod connecting the wheels is called the car suspension. Definition of car suspension: The suspension system refers to all the force-transmitting connection devices between the car frame and the axle or wheels. Its function is to transmit forces and torques between the wheels and the frame, buffer the impact from uneven roads to the frame or body, and dampen the resulting vibrations to ensure smooth driving. Non-independent suspension system: The structural feature of a non-independent suspension system is that the wheels on both sides are connected by an integral axle, and the wheels together with the axle are suspended under the frame or body through an elastic suspension system.
I've been repairing cars for decades. The critical component connecting the wheels is called the tie rod, which directly links to the steering system, ensuring the wheels move synchronously when turning the steering wheel. If this part wears out, bends, or has loose ball joints, you'll feel steering wheel vibrations, unstable handling, and uneven tire wear. I've seen too many car owners neglect this small component, leading to dangerous lane departures at high speeds. I recommend checking it every two years, especially during rainy seasons to prevent rust. If you notice abnormal noises or play, replace it immediately - parts plus labor cost just a few hundred, inexpensive but life-saving. Regular maintenance should include lubricating the joint sections, which can extend its lifespan two to threefold. It's also related to wheel alignment - remember to recalibrate after replacement, otherwise tires wear faster and fuel efficiency suffers. Safe driving starts with a solid foundation.
What I learned after driving for several years is that the rod is called a tie rod, specifically connecting the wheels to the steering mechanism to coordinate wheel movement during turns. Last time, there was a clicking sound when turning right, and the shop inspection revealed the tie rod end was worn out; replacing it cost over 400, and the steering became precise immediately. The manual recommends checking it every 50,000 kilometers—don’t delay until it becomes severe. For my daily commute, I pay special attention to these small components, as even minor wear can affect handling stability. I advise car owners to regularly listen for unusual noises from the chassis—any odd sound is a warning sign. After replacement, a wheel alignment is necessary to prevent abnormal tire wear. Safety comes first, and this investment is worth more than coffee money.
