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.

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.

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

Grinding process Grinding process

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.

Domestic gears of similar products Domestic gears of similar products

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.

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.
