The drum test brake is to install the friction pad of the Henan truck accessory manufacturer on the surface of the two arc brake shoes, take one end of the brake shoe as the support point, and increase the driving force from the other end to make the brake shoe press towards the inner side of the brake drum and brake. In the hydraulic mechanism pump, the piston rod of the Henan truck accessory manufacturer of the brake master cylinder immediately promotes the brake shoe; In the event of air impact braking, narrow air will promote the rotation of a camshaft to make the brake shoe extend outward. When the brake working pressure subsides, the return torsion spring pulls the brake shoe away from the brake drum, thus eliminating the brake.

Previously, there was a message on a customer's message board saying that they had just bought a car with a 504, which ran very well on the new road and didn't consume too much fuel. However, once they arrived in the plain area, their fuel consumption increased, and I couldn't accept this fuel consumption. She said that when I bought a car at that time, the people at the 4S store told me that high-power cars not only ran fast but also saved fuel, but now it doesn't seem like much, Is the market sales deceiving me? Today, people will come to briefly explain to everyone whether high-power cars are indeed fast and fuel-efficient.

If the Nitrogen Oxygen Sensor is broken, it will no longer burn urea. Damage to the nitrogen and oxygen sensor will also lead to failure to refuel, insufficient power, CAN line communication failure and other failures. You can use the urea pump test bench or the NOX sensor test function on the decoder for testing. A qualified test result indicates that the sensor is normal, and an unqualified test result indicates that the sensor performance is poor.

Both oxygen sensor and nitrogen oxide sensor are very important sensors in automobile exhaust emission system. They play a key role in monitoring and controlling engine emissions, but there are obvious differences between the two.

For over two decades in the tech industry, I've seen countless innovations come and go. But few have consistently delivered as much value in industrial settings as a robust Nitrogen Oxygen Sensor.

This article shares a long-term, field-based observation of truck ABS sensors following a real highway accident. From failure patterns and installation errors to the difference between active and passive sensors, it explains why this often-overlooked component plays a decisive role in heavy-duty vehicle safety.
