ATV deviation refers to the obvious angular difference in the direction control of the vehicle during the forward process, which causes the vehicle to not go straight when there is no steering, or a large turn or unable to turn when it is turned slightly, which are all vehicle deviations. ATV runaway is a more common type of failure with very high safety risks. When a new car is bought, it will have a lesser degree of runaway. This is due to the lack of running-in of vehicle components. This phenomenon usually occurs in 2 to 3 weeks. Disappears within. If deviations occur for a long time, professional diagnosis is needed. The deviation of the ATV is mainly caused by the failure or control of the steering system. It is mainly divided into two reasons: the road cause and the vehicle's own failure. The road cause is the excessively high and low inclination of the road, which causes the car body to lose balance and the control force. Deviations occur. ATVs usually travel on complex terrain, so deviations are normal. Another reason is the failure of the vehicle, that is, when the road surface is flat, the vehicle still shows obvious deviation and the direction cannot be controlled. The following components may be faulty: 1. Insufficient air pressure in the tire; 2. The degree of tread pattern wear is inconsistent; 3. There is a problem with the suspension system design; 4. The suspension is injured, deformed, or shifted; 5. The quality of the steering system will also affect the straight-line driving of the car. Due to the large wear clearances or loosening of the bearings, kingpins, and bushes, the connecting parts will cause the car to swing its head during driving and cannot maintain a normal motion trajectory. If the steering knuckle arm or steering knuckle is deformed, it will generally cause the car to veer off in one direction. The most serious is that the horizontal tie rod ball head is severely worn and loosened, which will cause steering failure and the car will lose control completely; 6. Caused by the brake. When the disc brake is braking, the brake fluid pushes the piston outward, and the piston pushes the brake pad and the brake disc to serve the purpose of braking. The piston needs to overcome a certain resistance (that is, the starting pressure) when it moves outwards. If the resistance is not the same, it will affect the time and force of the brake pads on the brake disc, causing the brake to deviate. The drum brake must first overcome the pulling force of the brake shoe return spring (that is, the threshold pressure), and then cause friction between the brake shoe and the brake drum to generate a braking torque. If the design of the drum brake on the return spring force is not very high or the return spring is stuck, then the force to overcome the brake shoe return spring when braking is different. The magnitude and speed of the braking force generated by the left and right brakes Variations, resulting in braking deviation. The gap between the left and right brakes and the shoe pads can also cause the brake to drift.
If the brake system or wheel wear of the ATV causes a deviation, it needs to be repaired at a professional repair shop to avoid safety accidents during use.
