Riveting brake linings is the most important process in the production and repair of the brake system in trucks and delivery vehicles. Rivets for brake linings play an important role, connecting the lining with the rest of the system elements . This requires precise selection of materials, tools and the appropriate technological process to ensure the durability and reliability of the brake system. In this article, we will discuss the riveting process, the selection of the right rivets and tools that will help to obtain perfectly attached brake linings.
Selecting a rivet for brake linings is essential for the correct execution of the entire process. Rivets must be matched to the shape of the holes in the linings and meet the manufacturer's requirements. The most commonly used materials for rivets include steel, brass and copper. A properly selected rivet ensures high quality of the connection and appropriate durability of the elements.
The rivet length should be matched to the diameter of the hole in the lining. The formula for calculating the rivet length is:
for semi-tubular rivet A = 0.5 – 0.75 * d
for tubular rivet A = 0.8 – 1.0 * d
Example :
For a rivet with a diameter of d = 8 mm, the rivet shank length A should not protrude from the jaw hole less than 6.4 mm, but more than 8 mm. These values allow for precise fastening of the linings, which prevents them from loosening during operation of the brake system.
When riveting brake linings, it is essential to use the right tools . The right riveter and anvil must be selected to ensure the correct pressure. The riveter manufacturer and the brake lining manufacturer provide guidelines on the forces that should be applied during riveting to maintain a safe and quality joint.
In addition, some manufacturers require that a pre-tension of 300 N be applied before the brake lining insertion process begins . Special rivet drivers with a pre-tensioning device offered by Textar fit most popular riveting machines.
It is important to rivet brake linings from the inside to the outside of the shoe. This means that the process starts from the center and then moves to the edges. This method of riveting ensures even and stable attachment.
After the brake lining process is complete, it is essential to check the quality of the work performed . This is done by lightly hitting the brake lining with a hammer, which allows you to hear whether the linings are properly attached. A dull sound indicates loose linings, while a clear, distinct sound indicates properly riveted brake linings.
Another way to check is to use a valve gauge, which can detect the presence of voids under the lining. A void larger than 0.15 mm, which is located below the first row of rivet holes, can lead to noise during vehicle operation. Finally, each lining should be checked for cracks, especially in the area of the rivets. If they occur in this area, it may be an indication of improper machining.
Riveting brake linings is a precise process that requires the right materials, tools and maintaining the right technological standards. To ensure the reliability of the braking system in your vehicle, remember to choose high-quality rivets for brake linings and use tools in accordance with the manufacturers' instructions.
