現代の推進システムがますます複雑化したことで、計測機器や試験システムに対する要求が増大しています。主要推進システムコンポーネント（ICE、ハイブリッドエンジン、電動パワートレイン、トランスミッションなど）の並行開発を行うには、可能な限り早い段階でトランスミッション試験を実施する必要があります。AVL Transmission TS™は、開発工程を通じてあらゆるトランスミッションの妥当性確認を管理しやすくなるように設計されています。AVLには、乗用車、軽量・大型トラック、バス、トラクター、オフロード車などのトランスミッション試験システムの開発に長年の実績があります。これまでの推進ユニットを適切なAVL駆動ユニットに置き換えるソリューションを提供しています。これらのソリューションは、耐久性、機能性、パフォーマンス、NVHなどの幅広い用途に適用できます。

e-モビリティに生じる新たな課題

完成車メーカーとサプライヤーは、新しい推進システムコンセプト用のコンポーネントとシステムを開発しています。これまでAVL駆動ユニットの要件は、ICEのデータによって構成されていました。純電動推進システムへの移行に伴い、AVL駆動ユニットは電動パワートレインのデータにも対応しなければなりません。つまり、ICEと比較して、e-モーターの設計において、出力密度と速度を向上させながら小型化が図られたり、柔軟性を高めたり、派生型が増えたりしているということです。

Performance Testing - Light Duty Performance Testing - Heavy Duty E-Transmission Performance Testing - Light Duty NVH Testing

Performance Testing – Light Duty

An AVL DynoPrime drive unit replaces the internal combustion or hybrid powertrain in light duty applications. Its slim design and short length allow direct mounting to the transmission input shaft, even in transverse configurations. A engine model simulates the static and dynamic behavior of an ICE, including combustion-induced speed irregularities. This setup enables early-phase testing with high realism.

Performance Testing – Heavy Duty

In heavy-duty applications, our drive units meet demanding speed and torque targets without space limitations. Two, four, or more load machines with torque capacities up to 40,000 Nm are deployed. To reach higher torques, matched gearboxes may be used. These AVL systems allow for comprehensive testing of transmissions and heavy-duty axles, making them ideal for trucks, buses, and off-road vehicles.

E-Transmission Testing – Light Duty

The e-transmission test solution meets the required speed and torque of the replaced e-motor while fitting into compact spaces. It supports the variability of e-axles in both co-axial and offset configurations. An AVL DynoPrime with up to 20,000 rpm enables direct mounting in a transverse layout. Using a gearbox increases flexibility and supports co-axial setups. This ensures reliable e-axle testing without needing the original drive unit.

NVH Testing

For NVH testing, AVL drive units are acoustically optimized to meet low-noise requirements. The NVH chamber is directly coupled to the transmission, while load units are placed outside to maintain minimal ambient noise. This testbed enables precise noise and vibration analysis under realistic conditions – an essential factor for vehicle integration and overall customer experience.

Tailored Drive Units for Precision Testing

Our transmission test systems are engineered to validate a wide range of transmissions, addressing varying types, speeds, and power classes. The main challenge lies in integrating an ICE or e-motor within a compact, close axle arrangement. The AVL drive unit is designed to meet the necessary speed and torque requirements while ensuring compatibility with the available installation space. Our solutions are capable of handling the variability of e-axles in both co-axial and offset configurations, along with the intelligent mechanical connection of e-motors to transmissions.

The optimization of the design and validation process is a key benefit, as our systems allow for early-phase transmission testing, even without a fully developed propulsion unit. This reduces the likelihood of design changes in later development stages. In addition, AVL PUMA 2™ automation software adds significant value to the testing process by synchronizing data from all connected devices. This results in precise measurement and control, enabling faster transmission system development through various test types, such as transient, time-lapse, and road load simulation tests.
