1. In the primary maintenance of the leaf springs on the front and rear axles of the car, grease should be added to the front and rear leaf spring pins, and some grease should be applied between the back end of the steel plate and the sliding plate (including both ends of the auxiliary leaf spring) to contact the bracket Place. Always check whether the steel riding bolts are loose, and tighten them in time according to the specified torque.
2. Tire inspection
①Tyre precautions: always keep the tire pressure in line with the standard; check the tire when parking, take out the nails, stones and stones between the twin tires embedded in the tread; if the tire is damaged, it should be repaired immediately; control The working temperature of the tires. When driving for long distances in hot weather, you should choose a cool place to rest halfway, and do not drive at high speed to reduce the tire temperature; drive the vehicle correctly and choose a good road, and reduce the speed when there is a bad road; slow when turning Try to avoid using emergency braking and prevent tires from rubbing; Do not overload, and load should be evenly distributed; Keep the front wheel positioning, steering, braking, and driving devices with good technical performance; Try to choose tires with the same specifications, patterns, and new and old levels. The tires of the front axle and the rear axle should be rotated regularly; the tires of some vehicles have uneven one-way wear, but also pay attention to the regular reversing; the axle tires should be stored correctly, and they should be sun-proof, waterproof and oil-proof; when the car is parked for a long time, The frame should be raised to relieve the tire load.
②The inspection standards stipulate tires: the left and right wheels on the same axle should be equipped with tires of the same model and pattern; the tire pressure and load should meet the requirements; the depth of the tread center pattern should not be less than 2, and the tire surface should not be hard. Injuries and line exposure; the steering wheel shall not be equipped with retreaded tires; the amount of tire swing and bounce shall not be exceeded for small cars.
3. Large vehicles should not exceed 5; the rim should be intact and the nuts should be complete and fastened. The main reasons for tire blasting: inflation pressure is too high or too low; tire overload work; driving on uneven road bounce and impact, etc.
