Automotive spring lubrication method

Automobile spring: by a plurality of unequal length, unequal curvature of the plate. After installation, the ends naturally bend upward. When the road hits the wheel, the steel plate deforms, plays the role of cushioning and damping the vibration, and plays the role of guiding force transmission in the longitudinal arrangement. Most independent suspension adopts plate spring as elastic element, which can save guide device and shock absorber, and has simple structure.

Automobile spring is one of the most widely used elastic components in automobile suspension. It is an elastic beam of approximately equal strength, consisting of several alloy springs of equal width but unequal length (the thickness may or may not be equal).

Automobile spring lubrication method:

The new car entry period shall be conducted at the end of the trial operation period, and in summer and winter, at the end of the operation period. In the lubrication operation, the leaf spring is removed, the perforated bolt in the middle is opened, and then both sides of the steel plate are evenly coated with lithium grease or graphite grease. After installation, an oil film is formed between the two friction surfaces (it only takes time to replace a broken piece to complete a set of plate spring lubrication).

The lubrication of car springs has three advantages:

First, reduce friction and dispersed stress to prevent surface strain of steel plate;

Second, reduce the invasion of dust, soil and water to prevent corrosion;

Third, heat dissipation and cooling to prevent a decline in elastic strength.

Car spring lubrication should pay attention to:

Although the leaf spring lubrication has certain advantages, but the leaf spring lubrication should also have certain rules, such as the lubrication time of the southern leaf spring is generally quarterly lubrication, the northern lubrication every six months, can also be correctly mastered according to the mileage (often with oil drop method also plays a certain role in lubrication).
