Shock absorbers: types, construction, purpose, repair and equipment necessary for this


Recommended Posts

Bad shock absorbers – dangerous driving. The vehicle is due to their failure poorly manageable, the wheels have little traction with the road surface. This also leads to a malfunction of the brake system. The main task, which is carried out shock absorber in car, is to control and hold the wheel while driving. This avoids losing control of the vehicle.

Shock absorbers are also designed to damp vibrations that occur when driving on an uneven surface, off-road and when the speed changes. Springs do not always cope with the load. Consequently, the safety of the vehicle and passengers directly depends on the shock absorber. Therefore, it is necessary to pay special attention to the selection of these parts of the chassis of the car.

The structure and types of shock absorbers

Shock absorbers consist of a cylinder with a piston inside and a valve mechanism. The combination of such elements in this system allows you to damp the vibrations in a timely manner and prevent the car from swaying violently.

Varieties by the principle of action

The most common are hydraulic and gas shock absorbers:

  • Hydraulic shock absorbers put out the vibrations of the elastic elements of the suspension using oil that flows from one tank to another through a valve system.
  • Gas shock absorbers they also use liquid, but it is preliminarily “squeezed” by a small volume of gas.

  • Two-pipe .
  • Single-tube with gas pressure.
  • Two-pipe with gas pressure.

Single-tube have advantages, because the liquid in this device does not overheat. They are also practical: the housing can be installed up and down.

Two-pipe ones consist of two cavities, one has a piston with valves, and the second is necessary to partially fill it with oil and air. If they are absent or too few in design, then the shock absorber stops working or is compressed without resistance. In the event of such malfunctions, it is necessary to contact a car service or service station that has

Diagnostics of malfunctions of shock absorbers and the main causes of their failure

Checking the fault is quite simple:

  • If during driving the car does not shake and extraneous noise is not heard, then the shock absorbers function normally.
  • If in motion there are problems with braking, smooth running, fitting into a turn, and also the car cannot gain a certain speed, then it is necessary to pay attention to the condition of the shock absorbers. Such problems can lead to an accident caused by an increase in wheel slip vibration.

Most often, the main cause of the breakdown may be leakage of fluid through a damaged seal. This can happen in such cases:

  1. Wear of the sealing material due to friction.
  2. Sudden change in temperature.
  3. Dirt and dust are trapped in the shock absorber.
  4. Gas or air are trapped in the shock absorber.

To avoid breakdowns, it is necessary to seek the help of professionals in a timely manner, who will make a diagnosis and restore the parts if necessary. This can help

      Understanding the types of brake pads essentially means understanding the materials used in each type. This provides us with a clearer understanding of their names and functions and enables us to offer a reference for choosing the right brake pads.
      Friction Materials Composition
      The basic composition of brake pads currently available in the market consists of
      Shim Steel backing, steel backing adhesive friction material At KETULLA, the steel backing is formed using internationally standard 10mm stainless steel through cold pressing. The friction material comprises a binder, metal fibers, ceramic fibers, phenolic resin, aramid fibers, and various fillers, which are heat-pressed onto the steel backing. The role of the shim is to suppress vibrations, thereby reducing noise. It effectively reduces noise generated by braking. KETULLA utilizes stainless steel or high-quality heat-resistant materials for this purpose.
      We typically classify brake pads based on the proportion of key components in the friction material: semi-metallic, low-metallic, ceramic, or collectively referred to as Non-asbestos. In China, asbestos has been strictly prohibited from use in brake pads due to its significant environmental impact and adverse effects on human health. According to the revised regulation 《GB5763-2018》, this has been explicitly stated.
      Low Metallic
      link hidden, please login to view Low-metallic brake pads are the most economical option, as they typically consist of 10% to 30% metal fibers, phenolic resin binder, graphite particles, and other fillers. These fillers primarily serve to suppress thermal expansion and contraction of the composite material, thus enhancing bonding strength.
      Due to the presence of metal fibers in this formulation, research has shown that vehicles equipped with these brake pads may generate dust on our wheel hubs during braking. This dust, typically gray or black, is a byproduct of friction from the metal fibers and tends to accumulate around the wheel hubs due to its electrostatic properties, making the area appear dirty. Over time, this dust accumulation can also cause damage to the brake discs. However, the advantages of low-metallic brake pads include superior heat conductivity, strong friction capabilities, and shorter braking distances. These factors contribute to why we recommend using low-metallic formulations for truck brake pads
      “Due to their affordability, this is also why our factory sells the highest quantity of this type of brake pads. In many countries, customers primarily compare prices and performance when selecting brake pads, making them more likely to choose this type over others
      Semi Metallic
      link hidden, please login to view Semi-metallic brake pads have a similar composition to low-metallic brake pads, but with the difference that they contain 30% to 50% metal fibers. Additionally, they use larger graphite particles, which are more visibly apparent on the surface of the brake pads compared to low-metallic ones. Furthermore, their friction coefficient is slightly higher, with better heat conductivity and braking distance performance.
      They are generally suitable for use with truck brake pads. However, they are more likely to generate dust, and improper installation may lead to increased noise. In response to this issue, KETULLA continuously optimizes and adjusts the formulation, resulting in significantly reduced dust and noise generation probabilities.
      According to market feedback, the primary cause of noise is usually improper installation, indicating that our formulation optimization has been highly effective. Therefore, our purchasers can rest assured.
      Ceramic
      link hidden, please login to view Ceramic Brake Pads link hidden, please login to view Ceramic Brake Pads GF At present, ceramic brake pads are the most expensive. Ketulla’s ceramic formulation brake pads utilize high-quality ceramic fibers, graphene, and aramid fibers, without the inclusion of metal fibers. The price of ceramic fibers is significantly higher than that of metal fibers, but they offer superior heat conductivity and friction coefficients. Although there may be a slightly softer pedal feel, it does not affect the braking performance. More importantly, they result in much lower wear on the brake discs compared to other formulations, thus extending the lifespan of the vehicle’s brake pads.
