MAN brake drum

Advantages of drum brake
Drum brake drum is cheap and conforms to the traditional design. In the braking process of four wheel car, due to the inertia, the load of front wheel usually accounts for 70% to 80% of the total load of the vehicle. The front wheel braking force is larger than the rear wheel, and the rear wheel plays an auxiliary braking role. Therefore, in order to save cost, the car manufacturer adopts the brake formula of front disc and rear drum. However, for heavy vehicles, because the speed is not very high, the durability of brake shoes is higher than that of disc brake, so many heavy vehicles still use four wheel drum design.

Shortcoming:
The braking efficiency and heat dissipation of drum brake are much worse. The braking force stability of drum brake is poor. The braking force changes greatly on different roads, which is not easy to control. Due to the poor heat dissipation performance, a large amount of heat will be accumulated in the braking process. Under the influence of high temperature, the brake pad and wheel drum are easy to have extremely complex deformation, which is easy to produce the phenomenon of brake recession and chattering, resulting in the decline of brake efficiency. In addition, after the drum brake is used for a period of time, the gap of the brake shoes should be adjusted regularly, and even the whole brake drum should be removed to clean up the accumulated brake powder.

Mantrack&bus is a leading European manufacturer of commercial vehicles and a supplier of transport solutions. It is a subsidiary of Mann group, which is affiliated to Volkswagen Group. Commercial vehicle manufacturing has a long history in man: more than 100 years ago, man built the first truck and bus. In 2015, mantrack&bus had more than 35500 employees worldwide, sold 80000 cars and achieved sales of 9billion euros. The product range includes light trucks, trucks, buses, diesel engines, gas engines and various services related to passenger and cargo operation. Mann will also identify future logistics weaknesses through new digital products and services and introduce Rio as a special platform for 2016iaa commercial vehicle show, a new brand of Volkswagen Truck & bus in the field of digital solutions. Rio is an open, independent business and technology platform for manufacturers, providing digital services for the entire logistics ecosystem. The extensive data use of digital acquisition and processing and company collaboration is the basis of intelligent control logistics process. Therefore, all links in the transportation chain are not only data providers but also data users. Mann is the originator of Rio and is responsible for its development within Volkswagen bus group. On the electric traffic roadmap, Mann will show a city bus and a semi trailer for distribution and transportation in the scheme study of IAA auto show, and prospect the electric transportation in passenger transport and in city logistics.

A variety of truck options
Mann's classic truck solutions include: mantgl (7.49-12 tons), medium TGM series (12-26 tons), and TGS and TGX series with a total weight of 18-44 tons. With 640hp power and torque converter clutch, TGX can be used in vehicles with a total weight of 250 tons. The TGS product line for the export market provides strong trucks with a total weight of 18-41 tons for Russia, Asia and Africa. The cla series trucks manufactured by Mann in India weigh 16-49 tons.

New transport series mantge
The new transport family mantge occupies the classic share of light commercial vehicles with a permitted gross weight of 3.0-5.5 tons, and will become Mann's first solution for light transport tasks in the future. Based on two wheelbases, three top heights and three vehicle lengths, the body shape is similar to that of closed van freight cars and vans with windows, as well as a variety of structural options with single and double seat cab chassis. Man's target groups are in the logistics and construction industries, for example. However, the industry-specific needs from the handicraft industry and passenger transport are also the application fields of light trucks of man Truck & bus in the future.

Man and Neoplan's bus
The product series of Mann and Neoplan bus brands include tourist bus, intercity bus, city bus and bus chassis. With the help of city bus, intercity bus and tourist bus, the diversified man models are mainly used in the application field of economy. With its unique coach, Neoplan attracts customers who want to provide luxury travel experience for passengers.

High efficiency engine of manka bus company
The common rail diesel engine developed and produced by manka bus company is not only used in manka trucks, but also in manka and Neoplan buses. Not only that, many other manufacturers also use Mann engines in their commercial vehicles, construction and agricultural machinery, rail vehicles, as well as yachts and workboats. In addition to diesel engines, manka bus also provides natural gas engines. With an average market share of 39% in Europe, man has become a market leader in the field of natural gas passenger cars.
Mann is working on engine technology to continuously reduce fuel consumption and emissions. The increasing efficiency of diesel engine shows the strong competitiveness of man in the field of engine. In addition, the company also attaches great importance to the hybrid drive technology of passenger cars. As early as 2010, Mann's lion's city hybrid city bus has been successfully put on the market. In daily use, the diesel electric hybrid can reduce fuel consumption and carbon dioxide emissions by up to 30%. With years of experience in the electric power train and components of hybrid electric bus, Mann is able to provide mature electric transportation solutions. The series products of pure electric bus will be launched before 2020. In the field of trucks, Mann has also developed a concept car that is close to usable. Based on the urban scenario in 2012, the tractor semitrailer concept vehicle, which will be displayed at IAA commercial vehicle exhibition in 2016, has a further development compared with the 26 ton garbage truck envisaged at that time, and is designed for urban logistics.

All round service
Mannka bus company can provide customers with flexible and comprehensive services: whether it is after-sales, maintenance agreement, fleet management, driver training, or financing scheme, man can combine top-notch technology with customized services for customers.
