The lightweighting of automobiles is a major trend and is too important for energy conservation and environmental protection.†This is a consensus reached by the participants at the Automotive Components Lightweight Technology Summit Forum of the 2014 China Association of Automobile Manufacturers' Brake Branch recently held in Lingyuan City, Liaoning Province. .
The forum was sponsored by the China Automotive Industry Association's brake subcommittee, contracted by Lingyuan Municipal Government of Liaoning Province, and co-organized by Liaoning Jiutong Friction Material Co., Ltd.
The lightweight of a car is to reduce the car's trim quality as much as possible while ensuring the car's strength and safety performance, thereby improving the car's dynamic performance, reducing fuel consumption, and reducing exhaust pollution.
Experiments have shown that if the vehicle's vehicle weight is reduced by 10%, the fuel efficiency can be increased by 6%-8%; for every 100 kg of vehicle's curb weight, the fuel consumption per 100 kilometers can be reduced by 0.3-0.6 liters. To reduce fuel consumption, in addition to adopting new energy technologies, lightweighting is a very important measure. The gradual replacement of traditional heavy steel materials with lightweight materials has become an inevitable trend.
On the forum, Zhejiang Tianle New Material Technology Co., Ltd. and Liaoning Jiutong Friction Material Co., Ltd. introduced new achievements such as “Innovative Technology for Aluminum Alloy Composite Brake Discs†and “Brake linings for Aluminum Alloy Friction Platesâ€. . The weight of this new type of brake disc is reduced by more than 40%. In combination with a special brake friction disc made by Liaoning Jiutong Friction Material Company, the friction coefficient is stable, the braking performance is good, the braking distance is shortened, and the brake comfort is improved. Due to good heat dissipation performance, the temperature rise of the brake disc during braking is greatly reduced.
According to Si Wanbao, technical director of Liaoning Jiutong Friction Material Co., Ltd., the use of aluminum alloy brake discs or drums can reduce a lot of weight. The company used a "secondary refining residue after adding iron from blast furnace waste residue" as the main filler, made of anti-burning, wear-resistant "no asbestos, no glass fiber, no metal, non-ceramic nao new environmental protection, Lee waste , Emissions reduction of automotive brake linings.Overcome the friction between the conventional traditional products and aluminum alloy materials, the friction coefficient is too low, the wear resistance is not ideal. This product contains "secondary refining residue" products, not only Better wear resistance, but also better heat resistance, but also because of the "second refining waste residue" is an industrial waste, with a significant cost reduction features.
