Precision components and systems for transmissions in passenger cars and commercial vehicles

Recent years have seen the development of several new types of transmissions that have already made it into volume production. Automated manual transmissions, double clutch transmissions and CVTs have joined the conventional “manual transmissions” and “automatic transmissions with torque converters”. With its innovative components and systems, Schaeffler Automotive Technologies is significantly advancing the development of all types of designs and concepts in pursuit of increased driving comfort and reduced fuel consumption.

Rolling bearing solutions for electric mobility

Schaeffler offers a wide range of optimized bearing solutions that can be used in electric mobility applications such as electric axles.

The robust high-speed ball bearings or high-speed cylindrical roller bearings developed by Schaeffler for use in electrified drive systems can easily handle the high speeds achieved on the transmission input shaft.

The high-precision sensor bearings on the rotor shaft are equipped with a sensor that transmits the rotary position to the power electronics for controlling the electric motor accordingly. Current shunt bearings are characterized by an integrated shunt element that protects the bearing against damage caused by electric current.

The new angular roller unit (ARU) bearing concept used as a locating bearing on the intermediate shaft transmits axial forces in both directions.

Tandem ball bearings or tapered roller bearings with special DUROTECT B coating reduce friction on the output shaft. This makes the electric axle system even more efficient.

Damper solutions for hybrid vehicles

The dampers used in hybrid vehicles must fulfill high vibration damping requirements.

Among other products, Schaeffler offers high-performance dampers with a U pendulum. The combination of a pendulum-type absorber and arc springs achieves a degree of isolation of up to 99 % and provides excellent driving comfort even in challenging applications.

Dampers for dedicated hybrid transmissions with a slipping clutch isolate vibrations using a conventional pressure spring and provide protection against peak torques.

Bearing supports for transmissions and rear axle drives

Schaeffler focuses on systems and offers solutions for the entire bearing package used in a transmission system – with efficient use of space, high load capacity and low friction. This also includes solutions for radial and axial bearing supports of transmission shafts and gears, as well as complete planetary gear sets. When devising solutions, we look beyond the individual bearing, as we understand and consider the entire system. Conventional tapered roller bearings are being replaced by tandem angular contact ball bearings with two different pitch circles that are designed to support pinions and differentials in the front and rear axle drives. Less friction, and therefore reduced heat build-up, results in significantly higher efficiency which in turn leads to improved fuel economy. This allows modern cars to lower exhaust emissions and consume less fuel, while extending the service life of the individual components.

Clutch / Gearshift systems / Synchronization

Shifting with feeling: In manual transmissions, Schaeffler’s components for clutches, gearshift systems and synchronization ensure quick, secure and precise gear changes. The clutch-release systems and self-adjusting clutches require very little force to operate and feature automatic wear compensation.

Gearshift and synchronization components deliver smooth shifts. We work closely with our customers as an engineering partner, starting with the initial stages of system development. Schaeffler’s system expertise is required here.

Synchronization components and synchronization systems are some of the essential components in a vehicle transmission and determine the comfort of manual transmissions, automatic transmissions, and double clutch transmissions. Synchronization systems will also be needed in future applications of hybrid transmissions, some with new functions. The market-oriented expansion of the portfolio to include synchronization systems means that Schaeffler is in an excellent position here. With the Eco System and Short System, the portfolio portfolio now comprises tried-and-tested components with standardized design as well as new solutions for optimizing the design space without sacrificing performance.

Solutions for double clutch and automated transmissions

Automated solutions come in twos: We are a vital technology partner for the automotive industry in the development of new transmission designs. Recent innovations include automated manual transmissions and double clutch transmissions that offer comfortable operation and dynamic performance while reducing fuel consumption. A concept used in hybrid drives is the hybridized double clutch transmission. By integrating an electric motor, all the hybrid features – such as the start-stop function, regenerative braking and the ability to downsize the internal combustion engine through a booster function – are available without adding extra components.

Solutions for automatic transmissions

Innovative technologies that are customized to suit regional requirements: One of Schaeffler's recipes for success is having a product range that is also tailored to the requirements and demands of individual regions.

Enhanced comfort through automatic transmissions: In addition to supplying the complete set of bearings for shafts and gears as well as planetary gear sets, Schaeffler also offers components for automatic transmissions, especially torque converters and torque converter lockup clutches. By combining hydrodynamic converters and electric motors, Schaeffler is offering a key technology which should help ensure further growth of hybrid drives on the North American market.

Components such as pulley sets, multi-link chains and hydraulic components for continuously variable transmissions (CVT): The CVT is a very convenient solution for high-density traffic with widely varying driving speeds. The increasing worldwide requirements with regard to emissions and fuel consumption also make a very strong case for the use of CVTs: The continuous adjustment of the gear ratio without interrupting the tractive force means that the engine can always be operated in the section of the data map that is most favorable in terms of fuel consumption. The fuel consumption figures that this produces are on the same level as those of manual transmissions operated in the ideal manner. Hybrid concepts can also be optimally combined with CVT components.

Torsion dampers

Schaeffler has extensive technical expertise in the field of dampers in the drive train. Groundbreaking developments such as the dual mass flywheel and torsion dampers integrated into clutch disks help to ensure driving comfort for today’s drivers.

Schaeffler was the first manufacturer in Europe to successfully develop a dual mass flywheel (DMF) for high-volume production. It is most certainly the best method of damping torsional vibrations in the drive train. The innovative DMF with centrifugal pendulum-type absorber is another key component for improved fuel economy and lower exhaust emissions, and it enables even higher driving comfort at the same time. Schaeffler has transferred the operating principle of the centrifugal pendulum-type absorber to other drive train solutions, for example, it is used in the torsion damper of torque converter lockup clutches.

Today, there are also components available that can dampen vibrations in the engine, such as dampers for crankshafts and balancer shafts.

Robust design and perfect sealing: The pilot bearing supports the transmission input shaft in the flywheel. This requires a long service life, which Schaeffler achieves by means of optimum sealing. This prevents clutch wear dust entering the bearing. The large grease reservoir guarantees a long running life, while the design is convincing through its insensitivity to axial motions.

Wide angle dampers give an additional increase in torsional vibration insulation and service life in all forward-looking concepts for truck transmissions. Vibration-damping components are now also available for the belt drive on the engine.
