Sidem quality standards for powers of motion on ball joints

Evaluated: Approved: Valid from: 6-10-2012

1. Purpose

To embed unequivocal agreements for testing of tie rod ends and ball-joints for cars and trucks.

2. Application field This Sidem quality standard is applicable for testing all suspension parts. 3. Technical information

3.1. Drawing

3.2 Minimal turning moment

When using Nylon nuts a min. torque must be achieved, so that the assembling of the parts will give no problem. By using an internal hexagon or flat face key is it possible to apply 0.5Nm without loosing the clearance-free movement of the part .

3.3 Decreasing of moving forces All moments of movement will be decreasing by 20-30% after a day of assembling. 3.4 Decreasing of moving forces after assembly

After use or after a test, the turning moment will be decreasing once more. A drop to 0Nm is possible, but 0K, as long as no clearance is appeared.

3.5 Purpose

The final purpose is to make the best parts which means clearance =0 turning moment is 0 Nm, and the parts must be functional good for long time.

4. How to measure 4.1 Primary turning moment in Nm.

This is the maximal value before the pin is moving into the housing. This value is measured with torque wrench . The needle of the torque wrench is indicating the value.

4.2 Dynamical turning moment in Nm.

The measuring instrument must be turned around 3 times which gives the grease the possibility to go around the ball pin. After this will be a read out while moving slowly.

4.3 Movement force

This is not required because it is a relation of the turning moment measurement.

4.4 Elasticity

The measuring is done on a Tensile strength machine (Zwick), the clamping must be adequate so that the measurement is not negatively or positively influenced.

4.5 Push & pull

The ballpin is pulled out of the assembly on the Tensile strength machine while the maximum force is recorded. If the assembly has a backplate than can the ballpin be pushed through the backplate also. The clamping must be adequate so that the measurement is not negatively or positively influenced

4.6 Minimum welded force of connection bar to housing (stabiliser link)

This connection can be tested on the tensile strength machine and with a torque key. Both tests have to happen with the dedicated tools.

4.7 Minimum disconnection force (Inner Tie Rods with Tube)

This connection between ballpin and pressed on tube can be tested with a torque key. The ballpin has to be tightly clamped while turning counterclockwise with torque key on the tube. The tube cannot move only then is the test succeeded.
