source of technology Just like the Hanma engine, the Hanma gearbox is a new gearbox product developed by Valin in cooperation with Europe's top gearbox design company. It uses foreign advanced technology and inherits European noble blood. Hanma Transmission Active Lubrication System The HMA transmission oil grade is GL-4 80W/90, and the domestic similar product lubricant is GL-5. Although the GL-5 oil grade is higher than the GL-4, the GL-5 grade oil contains the additive sulfur phosphor Corrosion can occur on non-ferrous metals (synchronizers), and Hanma's gearboxes can create high-quality benefits with low-quality oils. effect Mandatory lubrication of various components and key points inside the gearbox; it compensates for the defects of long-uphill and long-downhill that are caused by traditional splash lubrication, resulting in poor lubrication; it greatly improves the reliability and service life of the gearbox. Maintenance cycle Domestic similar bad review splash lubrication method Lubricity-free pumps and fuel injection pipes are not adequately lubricated, especially when they are on long downhill slopes or long uphill slopes. Some gears are poorly lubricated and do not even lubricate, causing premature damage to parts. Hammer Gears Helical Tooth Grinding Technology Gears It adopts a full helical gear structure with a larger gear meshing contact surface and longer gear service life. After carburizing heat treatment, grinding is performed and the tooth profile has a high precision, up to DIN7, which effectively improves gear meshing. Make the transmission smoother, lower noise and higher transmission efficiency. Spur gears are used. Under the same conditions, the contact surface is smaller than that of the helical gears. The bearing capacity does not grind after heat treatment, and the accuracy is low. It is a national standard, and it has a large noise, a short service life, a low transmission efficiency, and a large fuel consumption. Hanma transmission spindle assembly comparison Hanma gearbox rear sub-box system Using five small, lightweight, compact planetary gears to distribute the output torque of the sun gear, the bearing capacity is large and the transmission efficiency is high. The rear sub-tank of the Hanma transmission has stronger anti-overload capability. Rear box of domestic similar products Shafts and gears are treated with a welding process that is susceptible to fatigue and fracture when overloaded. Hanma gearbox full open structure and housing The assembly process is simple and easy to maintain; the front box, main box and rear box are made of aluminum alloy material, and the blanks are imported from Germany. Shift tower and assist cylinder Light weight, clear shift, plus assist cylinder shifting force is greatly reduced, truly enjoy the quality of the truck. Hanma Patented PTO Products Small size, weight about 3Kg, far less than the weight of similar products (30Kg); output torque 1000Nm, no need to pull files to force the work; do not need to add a separate lubricant. The Hanma gearbox uses a German brand synchronizer. Under normal conditions of use, the Hanma gearbox synchronizer uses 200,000 kilometers without maintenance. What is the ignition coil?
The core components of the ignition device are the ignition coil and the switching device, improve the energy of the ignition coil, the Spark plug can produce enough energy spark, which is the basic condition of the ignition device to adapt to the operation of modern engines.
A high-quality ignition coil has several unique characteristics that make it an important part of the engine. Here are five key characteristics of a quality ignition coil and its role in the engine: Coil Pack,Auto Part Nissan Sunshine Ignition Coil,Auto Engine Ignition Coil For ,Oem Ignition Coil For 1D auto parts , https://www.1dauto.com

1. Efficient energy transfer: A high quality ignition coil is designed to transfer power from the battery to the spark plug with maximum efficiency. It minimizes energy loss and ensures that the spark plug receives the required voltage to ignite the fuel-air mixture.
2. Durability and reliability: High quality ignition coils can withstand extreme temperatures, vibrations and other harsh conditions in the engine compartment. It is made of high-quality materials and has undergone rigorous testing to ensure its durability and reliability.
3. Consistent performance: A high quality ignition coil provides consistent performance over its service life. Regardless of the operating condition of the engine, it produces a strong and sustained spark each time, igniting the fuel-air mixture.
4. Improve fuel efficiency: A high-quality ignition coil can improve the fuel efficiency of the engine, ensuring that the fuel-air mixture is effectively ignited. This reduces waste of fuel and improves the overall performance of the engine.
5. Reduce emissions: A high-quality ignition coil can also reduce engine emissions by ensuring that the fuel-air mixture burns efficiently. This results in lower levels of harmful pollutants emitted from the engine.
In short, a high-quality ignition coil is a key component of an engine that ensures efficient energy transfer, durability, reliability, consistent performance, improved fuel efficiency and reduced emissions.
Heavy-duty truck gearboxes have always been one of the relatively weak technical forces of domestic heavy-duty truck manufacturers. Therefore, many manufacturers are reluctant to manufacture heavy-duty truck gearboxes themselves. Instead, they purchase other manufacturers because this not only eliminates the need for after-sales services. The trouble can also pass the risk to the supporting manufacturers. But trucks are a system. The matching between parts is an important guarantee for the quality of trucks. In addition, the gearbox is one of the key parts of trucks. Independent production can not only ensure the stability of truck performance, but also reduce the dependence on buyers. Therefore, we developed and produced our own home gearbox.
