What Causes the Bumpy Sensation When Driving the Chery Ant at Low Speed?
3 Answers
The bumpy sensation experienced when driving the Chery Ant at low speed is due to a mismatch between the spring parameters and shock absorber parameters. Below is an introduction to Chery Automobile: Introduction: Chery Automobile's manufacturing plant is located in Wuhu, in the eastern part of Anhui Province. Currently, the company has established three major passenger vehicle production bases in Wuhu, Dalian, and Ordos, with an annual production capacity of 900,000 vehicles, 900,000 sets of engines, and 800,000 transmissions. Models: Chery's automotive brands include Chery, Karry, Qoros, Cowin, as well as two premium brands, Jaguar Land Rover. Cowin and Rely have been discontinued. The Chery brand is the largest under the Chery umbrella, and the company has continuously pursued reform and innovation, achieving significant improvements in product strength and quality.
I've seen many similar cases over the years. The Chery Ant's bumpy ride at low speeds, like going over small bumps, is mostly caused by suspension system issues. The car's chassis is inherently on the stiffer side. If the shock absorbers are worn out or the springs are deformed, you'll feel even small road protrusions noticeably below 20 km/h. Another often overlooked issue is tire problems – if the tire pressure differs by more than 0.2 bar between sides, or if there's tire bulging, uneven force distribution during wheel rotation can make the whole body shake. Excessive rear axle half-shaft clearance is also a potential culprit, especially if you hear clunking noises when turning. When encountering this situation during daily school runs, I recommend first checking all four tires with a pressure gauge to rule out this simple issue.
Last time I drove my friend's Little Ant, I noticed this issue—the steering wheel was shaking when maneuvering at low speeds. Later, he took it to a mechanic and found out that the front suspension's control arm bushings were cracked. These electric vehicles have a short wheelbase, so even minor play in the chassis components gets amplified, especially when going over speed bumps—the rear wheels bounce more noticeably. If the steering wheel vibrates enough to make your hands numb, you should also check the tie rod ends. When the rubber deteriorates, metal-on-metal contact will definitely cause jolts. As a side note, if you hear a clunking noise over bumps, there’s an 80% chance the brake discs, pads, or caliper brackets are loose, and you should address it immediately. Don’t tough it out like my neighbor, who waited until the wheel hubs got damaged—that’ll cost you hundreds more to fix.
