What is the development trend of trailer axle?
The axle, together with the engine and transmission, is called the three power core assembly of the trailer. Although the axle is not as often mentioned as the engine and transmission, it plays a role in the process of automotive power transmission, and plays a decisive role in the driving power and stability of the vehicle.
The basic function of the trailer axle is to transmit the applied force and torque in all directions between the frame and the wheel:
(1) The engine torque from the universal transmission device is transmitted to the driving wheel through the main reduction tire, differential and half shaft to achieve the reduction of speed and increase of torque;
(2) Change the transmission direction of torque through the bevel gear of the main reducer;
(3) The differential function of wheels on both sides is realized through the differential to ensure that the inner and outer wheels turn at different speeds;
(4) Through the transmission of the main reducer gear, reduce the speed and increase the torque;
(5) Through the axle housing and the wheel, the bearing and force transfer function is realized.
With the rapid development of Chinese trailer axle market, the related core production technology will become the focus of attention in the industry. Now the automobile industry is generally developing towards energy saving, environmental protection, comfort and other aspects, which to a certain extent drives the axle to specialization, lightweight, high efficiency and other directions.
(1) Specialization: The axle industry will gradually improve the product spectrum classification according to the specific use conditions of vehicles, and provide specific products for market segments;
(2) Lightweight: With the introduction of the weight charge and fuel tax policy, lightweight has become the general trend of the development of trailer, axle will also use more new materials, structure design can be optimized;
(3) High efficiency: the production of sturdy and durable, high mechanical efficiency of the axle has become the goal of various enterprises, such as the trailer axle produced by Shandong DARO Group, while reducing the weight, successfully improve the use of strength and durability and other performance, can be in full load for users to expand the bearing range, no load fuel saving, energy saving and efficiency;
(4) Disc brake widely used: disc brake has been widely used in Europe and the United States, and now it has become more and more the trend of domestic transportation industry. The disc axle produced by DARO Group adopts integrated alloy brake disc, which is wear-resistant, crack resistant, efficient heat dissipation, convenient maintenance, sensitive braking and stronger stability, fully in line with industry standards;
(5) Wide application of electronic system assisted braking technology: ABS system will be gradually promoted to the trailer industry, and ESP, EBD and other technologies will also be gradually applied.
