The history of automotive with diaphragm accumulator
On January 5, 2023, BYD Yang wang brand officially released, the new brand also brings "Yang wang U8", "Yang wang U9" two models, of which Yang wang U8 is positioned in the medium and large SUV, look up U9 is a two-door sports car, in the eyes of the Chinese people, in the past, everyone said that the Chinese brand chassis technology and adjustment level is not good, the car is not fun to drive, Comfort is always a little off. However, in the future, this statement is afraid to change, BYD officially released Yunchariot intelligent body control system, through three systems to break the technical barriers created by foreign car companies and suppliers. What is the magic of the Unchariot system that allows us to enjoy the comfort and handling of the chassis? Technology is king and innovation is based on BYD, which has added hydraulic energy storage equipment to the chassis, making Biya's success in breeding four sets of Yunnian systems, including Yunnian C intelligent damped body control system, Yunnian A intelligent air body control system, Yunnian P intelligent hydraulic body control system, and the future can dance Yunnian -X.
Aboutthe Yunlima-P, this body with intelligent hydraulic body control system will be the top of the off-road world. It is mainly based on the precise sensing system, the intelligent calculation system, the control of the oil intake of the shock absorber, the damping adjustment and the stiffness adjustment to achieve the dynamic adjustment of the body. The Unian-P is mainly used in off-road or SUV models. The U8 will be the first model to be installed, and the next models of the new F brand are also expected to be equipped with Yunnin-P technology.
The intelligent hydraulic body control system of Yunnin-P allows the suspension stroke to be adjusted up to 200 mm, enabling simultaneous lifting of four wheels and individual lifting of a single wheel. At the same time, it can cope with a maximum wading depth of 1 meter, and the lifting capacity can reach 5 tons, and the stiffness of the suspension supports 3 levels of adjustment.
Previous suspension systems, including CDC suspension, MRC electromagnetic suspension, and even air suspension, these components are more fragmented. For Chinese brands, what suppliers give, can only use what, there is no independent control, and there is little space for car companies to adjust development.
The Unchariot system redefines the previously passive suspension system, transforming it from passive to active. A suspension that can feel and think is very important.
The Yunlima-P also features a four-wheel linkage. This function is mainly used in extreme off-road road conditions, when the unilateral wheel or diagonal suspension, is also commonly known as the cross-axis road conditions, the four-wheel linkage function can transport additional oil for the suspended shock absorber, further lengthening the suspension travel, so that the wheel as close to the ground as possible, to ensure that the four-wheel power can be effectively output. The Uni-P's four-wheel linkage enables the vehicle to have a maximum wheel differential of 620mm, comparable to the suspension system of a hard bridge.
All of the above functions are inseparable from the contribution of the diaphragm accumulator to the vehicle chassis system, which has a high energy density and working efficiency. The relatively stable pressure of the accumulator can also improve the working efficiency of the engine, hydraulic pump and hydraulic motor. The cooling effect when the medium evaporates can be used to regulate the engine and its intake temperature to increase the liter power of the engine
Since 2023, the company has vigorously developed diaphragm accumulator products, invested millions of dollars in the research and development of diaphragm accumulators, and built the factory into a professional commitment to the production and research and development of hydraulic components, products involving high pressure ball valves, solenoid valves, safety balls, globe valves, QXF, and has passed the ISO9001-2008 international quality standard certification.
