Gasgoo Awards 2023 applicant:Air suspension system,chassis lightweight system from Anhui Zhongding Sealing Parts Co. Ltd.

Product: Air suspension system,chassis lightweight system 

Description

①Air suspension system: Automobile suspension system is the entire support system consisting of a spring and shock absorber between the body and the tire, it is the connecting device between the body and the wheel,it can transfer the forces and moments acting between the wheel and the frame, cushion the impact of uneven road surface to the frame or body,attenuating the resulting vibration and ensure the smooth running of the car.According to the difference of road environment and the signal of the distance between the car and sensor, the driving computer will determine the height of the body, and then control the air compressor and exhaust valve, so that the spring automatically compressed or extended, thereby reducing or raising the chassis clearance from the ground, in order to increase the high-speed body stability or the passing of complex road conditions. The air suspension system gives a car both the comfort of a car and the handling performance of an off-road vehicle. Air suspension systems include air compressors, control units, multi-system sensors, air springs, and more. ②Lightweight chassis system: The product is composed of control arm,ball join assembly and its support,front bushing and its support,rear bushing and its support and damper bushing.It is used to connect the wheel,subframe and damper, it can transfer the load and control the wheel travel track. It has an important impact on the safety,comfort and handling of the car.

Unique advantages

①Air control unit:Working pressure up to 21bar, it meets the requirements of air suspension pressure and supports more aerodynamic function at the same time.The service life reaches 1000hours,meeting the use of vehicle service life;1000 hours air control unit service life can guarantee 12000 times of  air storage tank inflation,twice per day,it is expected to be 6000 days.The use of Ndfeb magnetic steel, magnetic is three times that of ferrite;The motor shell is sealed, there is no high pressure gas inside the motor chamber, and the surface of the compression chamber is provided with anti-rust coating to prevent internal rust; Anti-icing design, desiccant performance support dew point reduction of 40K, to prevent freezing in low temperature environment. ②Lightweight chassis system:Control arm,rear bushing support and ball pin support are designed with forged aluminum, which has high material strength and low density, greatly reducing the unsprung quality of the vehicle, improving vehicle handling and comfort, and improving fuel economy and driving range of new energy vehicles;Ball head joint assembly adopts the upper riveting structure, which greatly improves the axial bearing capacity and increases vehicle safety compared with the traditional lower riveting structure products. The rear bushing adopts hydraulic bushing to improve vehicle comfort; The front overhang bearing arm and guide arm are combined to reduce weight and cost and save space.

Application

①Air suspension system:Lift and lower the body of the passenger car,provide a more comfortable driving experience for drivers and passengers.When driving at high speed on a horizontal road surface, the body becomes lower and the spring becomes softer, improve driving comfort.When driving on the uneven road surface, the body becomes higher, the spring stiffens, eliminates bumps, improves passability and handling stability. Prevent acceleration, deceleration and steering, longitudinal elevation and planting head and lateral tilt, keep the optical axis of the headlamp light unchanged to improve the safety of driving. It can also realize comfortable and convenient value-added functions such as welcome mode and loading mode through active suspension height control. ②Lightweight chassis system: automotive lightweight has formed a broad consensus in the automotive manufacturing industry, the lightweight of the chassis plays a pivotal role in the performance of the vehicle, aluminum alloy control arm assembly products and other lightweight chassis products are of high value, but also the core components of operational stability and comfort. This type of product can be applied to the front suspension of various types of vehicles, especially suitable for the compact suspension space, fuel economy and endurance requirements of high models.

Prospect

①Air suspension system:With the advent of the era of new energy vehicles, the appeal of new energy vehicles intelligent, while chassis protection air suspension system is no longer the exclusive high-end models, because the new energy vehicle chassis system stability requirements are much higher than pure fuel vehicles, air suspension system has gradually become the mainstream configuration of the new energy vehicle platform. AMK Germany, as a high-end supplier of air suspension system, is one of the top three leaders in the industry. Since entering the field of air suspension system business in the 1990s, it has continuously improved the product assembly technology, and has been deeply engaged in the industry for more than 20 years, supporting the world's leading vehicle manufacturers such as Jaguar, Land Rover, Volvo, Audi, Benz, BMW etc. The domestic air suspension market is in its infancy, and AMK China has been accelerating the improvement of the performance and cost optimization of the air suspension system supply chain in the Chinese passenger car market. AMK continued to develop steadily around the strategic goals of "localization promotion, technology iteration and upgrading, and industrial strengthening and completing". AMK China continues to promote the implementation of other self-produced hardware projects while launching air supply unit product assembly and production lines in succession to increase the proportion of self-produced hardware.Business of AMK China has made breakthrough progress, and it has also obtained orders from many domestic new emerging manufacturers and  leading vehicle manufacturers. Up to now, AMK China has received orders with a total output value of 7.314 billion RMB, and it is expected to get more orders in the future, especially new energy vehicle orders. ②Lightweight chassis system: Due to the needs of environmental protection and energy saving, the lightweight of automobiles has become the trend of automobile development in the world. The lightweight of automobiles is not only suitable for traditional fuel vehicles, for new energy electric vehicles, it is also very important to reduce body weight and achieve vehicle lightweight, because it is related to the main battery life of new energy vehicles. In recent years, the company has been vigorously developing chassis lightweight system assembly products, and the forged aluminum control arm assembly project has made breakthrough progress. At the same time, its  subsidiary Sichuan Wangjin Company, whose core technology is the ball joint assembly product, is the core safety component and performance component of the chassis system. It has the world's leading technology and has a very high technical threshold.With the continuous advancement of the company's lightweight chasis system assembly business, it has  obtained orders from many traditional OEMs such as Mercedes-Benz, Changan, GAC, BYD, etc. At the same time, it has made breakthroughs in the business of leading new energy enterprises and obtained relevant orders.
