Tires. 1) Observe the correct tire inflation pressure, you should check the pressure in the wheels, 2 times a month 2) Keep clean the wheels of your car 3) Use a special tire for cleaning air conditioning 4) Examine Tire imbalance at least in a week. 5) Always keep the back wheel in good condition inflated. 6) If your car is aimed rubber, the back wheel is better to have that installed on the right direction of movement of the car. 7) Strive to always carry a kit for rapid tire repair puncture: a special awl kit repair harnesses. 8) Try not to use sealants tire 9) You should always keep in set jack and pump. 10) It should be remembered that, having separated the rubber, the movement of the car changed dramatically. 11) To improve rear-wheel drive vehicle stability control company Pirelli recommends setting on the front axle Tyres with directional tread on the rear axle tires with an asymmetrical pattern.
12) Since producers of automobile tires are constantly updating their product lines, we advise you to seamlessly update the model used by you to your car, you have to update them in pairs on the axis. 13) If you have a car kit is an asymmetric tire, for even wear rubber, we advise you not less than two months to change it on the diagonal. 14) If you have to car kit is designed rubber, for even wear rubber, we advise you not less than two months to change its axis by keeping its focus. 15) Check and follow the correct torque the wheels of your car, remember that the tightening of the wheel runs diagonally to the desired use of a torque wrench. 16) Try as much as possible to make an external inspection of your wheels! 17) Remember that the use of Low profile rubber detrimental effect on the suspension of your car with the quality of road surface in our country!
These detailed characteristics require precise mechanical testing to ensure that the welding process is correct and that the mechanical properties of the joint are adequate. The test machine (materials testing equipment) that can apply dynamic loads (fatigue studies) and / or static (to control the load angle error) are used to check the mechanical performance of the welds. TESTS flexi N Such testing involves carrying out a bending test at four points, applying cyclic loading to verify the performance of the weld in regard to fatigue. The charge will be applied sinusoidal, which will go from the maximum load value up to 90% of that value. This tension is repeated for five million cycles or until the solder fails. If failure occurs, the part must be marked and the series belonging to the discarded.
Ca LOAD TEST CLICK This is the most essential tests. It is playing a regular load of constant amplitude, for three million cycles in a position and at an angle to simulate the actual stress exerted by a train of wheels on the railway line. The magnitude of the load and actuator position (angle of load application) is determined from the value of vertical dynamic stiffness of the plate bearing the railway line. Elements adapted tests on materials used are of polymer, for the following reasons: – Insulation: essential to ensure that interference will not occur. – Comfort: It has a high absorption / damping qualities.
Therefore, it is essential to confirm the validity of the benefits of these materials when subjected to high voltages. TESTS ON RIGID ELEMENTS normal load for this test are 25 and 95 kN, and applied for one minute. – Tensile strength: Looking for the residual deformation of the coil. A load of 20 kN is applied to the sheath steadily. Subsequently, the load increases to a maximum of 1.1 kN per mm coil inserted. This load is maintained for two minutes before the release of 20kN load up again. Once you spend a minute with this last load, the deformation is measured. The value of this residual deformation should be less than 0.35 mm – Value of the ultimate tensile strength: The average value must be greater than 1.65 kN / mm coil inserted. First aplica1, 1 kN per mm coil inserted. If you break the pod, it records the value 1.1. If there is breakage of the load is increased until failure or up to 2 mm kN. FATIGUE TESTING UNDER LOAD LATERL A device is used to simulate the load side of the railway. This lateral load of the compression type for the part in question. The test conditions are the real operating conditions.
