18 Kinds of Semi-trailer Tire Eating Phenomenon and Solutions
Among the components of a semi-trailer, the tire is the only part of the car that is in direct contact with the road. Since semi-trailers often run under various road and climatic conditions, the working environment of tires is also changeable and harsh. According to the survey, there is a common problem of tire eating in semi-trailers driving on the road, and worn tires even account for as much as 30% of the total number of semi-trailers. So, how can we improve the abnormal wear of tires and effectively extend their service life?
Case 1
eat tire phenomenon: abnormal wear on both sides of the tread of a single tire.
Solution: Check whether the tire pressure is too low or whether there is a problem with the tire quality.
Case 2
eat tire phenomenon: single tread in the middle of abnormal wear.
Solution: Check whether the tire has quality problems or whether the tire pressure is too high.
Case3
tire eating phenomenon: steering bridge tire tread wear is "S" shape.
Solution: Check whether the toe, steel ring, steering ball head and steering gear are fixed and loose.
Case 4
tire eating phenomenon: the rear tire tread is "S" type abnormal wear.
Solution: Check whether the steel ring, hub screw and axle head are loose.
Case5
tire eating phenomenon: abnormal wear of a certain part of the tire tread.
solution: check whether the brake hub is not round.
Case 6
eat tire phenomenon: two tires on the same axis, the inner edge of the wear is not normal.
Solution: Check whether there is a problem with the toe and knuckle kingpin.
Case 7
eat tire phenomenon: tires on the same axis, abnormal wear outside.
solution: Check if the toe size is correct.
Case 8
tire eating phenomenon: abnormal wear on the inside of the unilateral tire of the steering axle.
Solution: Check the kingpin of the steering knuckle.
Case 9
tire eating phenomenon: abnormal wear on the outside of the unilateral tire of the steering axle.
Solution: Check whether the front axle king pin and steering knuckle are deformed.
Case 10
Tire eating phenomenon: The inner side of the tire on the rear axle side of the vehicle is abnormally worn.
Solution: Check whether the gap between the hub bearings is too large, whether the hub and the bearing bush are loose (outward circle), and whether the half shaft guide is bent and deformed upward.
Case 11
Tire eating phenomenon: abnormal wear of tires on the rear axle side of the vehicle.
Solution: Check whether the steel plate center screw, steel plate pin sleeve and steel plate lifting lug are loose.
Case12
tire eating phenomenon: abnormal wear on the outside of one side of the rear axle and the inside of one side of the tire.
Solution: Check whether the steel plate center screw, steel plate pin sleeve and steel plate lifting lug are loose.
Case13
tire eating phenomenon: abnormal wear on the inner side of a single tire on the steering axle of a double front axle vehicle.
Solution: Check whether the king pin, hub bearing and ball head of the steering knuckle are loose, and whether the toe is too large.
Case 14
tire eating phenomenon: abnormal wear on the outside of a single tire on the steering axle of a double front axle vehicle.
Solution: Check whether the toe of the tire shaft is too small, and whether the steering knuckle king pin and shaft are deformed.
Case 15
tire eating phenomenon: abnormal wear of the inner side of the steering axle and the outer side of the first axle tire of the double front axle vehicle.
solution: check the steering synchronization and the suspension alignment of the axle.
Case16
Tire eating phenomenon: The coaxial tire on the steering axle of a double front axle vehicle is abnormally worn on one side and abnormally worn on the other side.
solution: check the steering synchronization and the suspension alignment of the axle.
Case17
Tire eating phenomenon: The outer side of the dual-axle tires of dual-front axle vehicles is abnormally worn.
Solution: Check the kingpin of the steering knuckle.
Case18
Tire eating phenomenon: There is no normal wear inside the tires on the two axles of a dual front axle vehicle.
Solution: Check whether the front axle king pin and steering knuckle are deformed.
Although semi-trailer tires are common, it is not safe to avoid them. As long as they are used and maintained correctly, this problem can still be alleviated.
