What Causes an Electric Tricycle to Pull to One Side?
2 Answers
Inconsistent tire pressure among the wheels causes the vehicle's center of gravity to deviate significantly from the central position, resulting in uneven weight distribution on the drive wheels. This leads to varying traction forces on each side, generating a turning moment on the front wheel and causing the vehicle to pull to one side. Below is relevant information: Additional details: A twisted frame or deformed front fork may cause one or all wheels to make incomplete contact with the ground or contact with the tire sidewall. In such cases, the overall frictional resistance and traction forces from the ground become highly complex, potentially resulting in front-wheel deviation. Electric Tricycle: An electric tricycles is a three-wheeled transport vehicle powered by batteries and driven by motors, used for carrying goods or passengers. It features tubular high-capacity, left-right lined, deep-discharge, traction-type batteries that can meet the demands of prolonged continuous operation. The batteries typically maintain their capacity for two years under normal use.
I've been thinking about the issue of electric tricycles pulling to one side for a long time, and the most common cause is problems with the tires on both sides. For example, if the left tire pressure is only 20 psi while the right is inflated to 35 psi, the vehicle will definitely pull to the right, just like a person limping when walking. Another factor is uneven loading—last time I was carrying goods, I had a bag of rice on the left and foam on the right, and the vehicle immediately drifted to the left. Don’t overlook the braking system either; if the brake pads on the right side are severely worn, pulling the brake will cause the vehicle to jerk to the right. Additionally, if the bearings in the steering column are loose, the front end will feel unstable, and even slight road unevenness can pull the direction off. Finally, check if the rear axle has been knocked or deformed—that’s the most troublesome to fix. I recommend using a tire pressure gauge to check all three wheels every two weeks; keeping the tire pressure consistent will save a lot of trouble.
