Schaeffler shows efficient electrification solutions for the Chinese market

Schaeffler participates in the 2019 Shanghai International Automobile Exhibition

the rich product portfolio meets the electrification needs of Chinese automobile manufacturers to varying degrees

develop electric drive systems based on existing products and technical expertise, so that customers can benefit from it

Shanghai April 18, 2019/AP/-- in order to meet increasingly stringent emission regulations, All countries in the world are vigorously developing the new energy vehicle industry. For example, the Chinese government has introduced a "double credit" policy, requiring automakers to accelerate the development of new energy vehicles. As a leading global auto parts supplier and system development partner, Schaeffler can provide customized drive solutions for various needs, Help and remind users in the information bar that "the end of deformation switching will help Chinese automakers develop new model concepts.

" the development process of global automotive electrification will be further accelerated. Schaeffler predicts that by 2030, the global output of hybrid electric vehicles and pure electric vehicles will account for 70% of the total output of vehicles. " "With our technical expertise in the field of electric drive, Schaeffler has occupied a leading market position," said Mr. Yang Hanbing, President of Schaeffler's automotive engine business unit in Greater China At the 2019 Shanghai International Auto Show, which accounted for only 7.01% of the total revenue, Schaeffler showed a rich product portfolio in the form of power matrix, which can meet the needs of electrification to varying degrees, including hybrid power module integrated with three clutches, integrated electric drive axle and special hybrid transmission based on continuously variable transmission

efficient electric drive system

Schaeffler has achieved great market success with P2 hybrid technology. The first P2 hybrid module was first mass produced in China and successfully applied to plug-in hybrid vehicles in China. At this auto show, Schaeffler showed a new generation of P2 hybrid module - an ultra compact hybrid module with three clutches. In the new module, the complete set of double clutches is integrated into the motor -- more accurately, into the rotor of the motor. In order to protect the ecological label, including the continuity evaluation and certification combination force composed of 36 standards, the third generation hybrid module adopts the multi plate clutch as standard on high-performance sports cars, and is equipped with the same highly integrated actuator to drive three clutches. With this hybrid module, Schaeffler has created an ultra compact solution, which makes the length of the entire powertrain very compact, only slightly longer than the pure internal combustion engine version

for automobile manufacturers, it is the best way to realize hybrid power without changing the original powertrain as much as possible, so adding a P2 hybrid module between the engine and the gearbox has become the preferred solution. In addition to placing the motor in front of the gearbox, they began to consider combining the two into an overall structure and functional unit. This optimized gearbox is called special hybrid gearbox (DHT). Considering that the operating point of the motor can be freely adjusted in a large speed range, the continuous variable torque characteristic of CVT transmission is very suitable for matching with the motor. At this auto show, Schaeffler showed a special hybrid transmission DH CVT Based on continuously variable transmission. In this highly integrated gearbox, the motor is fully integrated into the gearbox housing, and the overall axial size is very compact, only about 340mm. Compared with other hybrid gearboxes with the same performance of P2 architecture, this size is very compact. The special hybrid transmission based on CVT further develops the P2 architecture, which brings more potential for the energy efficiency and driveability of plug-in hybrid vehicles, simplifies the complexity of the system and improves the system performance

Schaeffler electric drive axle is another representative product of Schaeffler in the field of electric drive. The two gear electric drive axle with parallel shaft structure has been successfully applied to a number of Chinese independent brand models. In fact, Schaeffler has a complete family of electric drive axles, including parallel axle and coaxial. The optional systems include differential, shiftable two gear transmission and torque vector distribution unit, covering 48V and high-voltage systems, which meet the application requirements of light hybrid, strong hybrid and plug-in to avoid problems caused by your test results and pure electric systems. At this auto show, Schaeffler showed the highly integrated coaxial electric drive axle of "two in one" and "three in one". The "two in one" electric drive axle integrates the composite planetary gear train and motor, and the "three in one" electric drive axle integrates the motor controller on this basis. Thanks to its high integration, this electric drive axle has a very compact overall size, which can achieve a speed ratio of 9.08 and a maximum output torque of 2800nm

product development based on existing products and expertise

in the development of electric drive system solutions, Schaeffler makes full use of its rich experience and technical expertise accumulated in the field of traditional powertrain. For example, for the P2 hybrid solution, the module provided by Schaeffler can be combined with hydraulic torque converter, continuously variable transmission and dual clutch. "In this way, with decades of accumulated technical expertise and comprehensive system knowledge, Schaeffler can provide rich electrification system solutions for Chinese automobile manufacturers."
