As public transportation worldwide accelerates toward greater efficiency, energy savings, and comfort, innovations in drive systems have become a pivotal driving force of transformation. CDTL's independently developed dual-motor distributed e-axle, with its groundbreaking design, exceptional operational economy, and proven reliability, is increasingly becoming the preferred choice for leading bus manufacturers—injecting new vitality into modern urban transit.

A Technological Leap: From Centralized to Distributed for Intelligent Driving

The core advantage of CDTL's e-axle lies in its innovative dual-motor distributed drive design. By replacing the traditional mechanical differential with an industry-leading electronic differential control algorithm, the system enables precise torque distribution and independent control of each drive wheel.

This distributed drive architecture represents a major technological breakthrough. Its success is built on CDTL’s mature multi-dimensional cooperative electronic differential control technology, backed by extensive experience in developing torque distribution strategies for complex operating conditions.

Delivering Value: Space Optimization, Increased Capacity, and Lower Lifecycle Costs

Technological innovation immediately translates into tangible benefits/(value) for users. First, the removal of the mechanical differential enables significant weight reduction and a more compact axle design. Taking CDTL’s EA2100N product as an example, this design enables buses to achieve a truly flat low-floor architecture—greatly improving boarding safety and passenger comfort while increasing the effective standing area by approximately 20%.

This means operators can increase passenger capacity within the same vehicle length, or optimize vehicle size and weight to improve operational economy per kilometer.

Second, independent torque control of the left and right wheels enables vehicle torque vectoring, providing greater freedom in vehicle dynamics management. This enhances the response speed and precision of safety control systems such as IESS（Intelligent Electronic Stability System） and EASR（Electronic Acceleration Slip Regulation）, significantly improving handling stability and active safety.

At the heart of this system is CDTL’s self-developed electronic differential technology. It has undergone 14 years of iteration and over 100 million kilometers of real-world validation, ensuring a mature and highly reliable solution.

Additionally, CDTL guarantees a tire replacement interval of over 100,000 kilometers for buses equipped with the EA2100N e-axle, substantially reducing maintenance frequency and lifecycle costs. With a gradeability of 25%, the system empowers vehicles to tackle complex terrains such as mountainous and hilly regions worldwide, opening up broader market opportunities for bus manufacturers.

Global Certifications: Enabling Worldwide Deployment

Designed to meet global market demands, the CDTL 13T e-axle has obtained international E-mark certification and passed rigorous DV validation and years of real-world testing.

Notably, this e-axle series has become an ideal solution for high-capacity platforms such as articulated and double-decker buses. Its mature technology ensures excellent power performance, smooth operation, and stability—supporting customers in the efficient development and mass production of high-value models.

The CDTL e-axle is more than just a component—it is a strategic enabler helping bus manufacturers achieve product upgrades, improve operational efficiency, and expand into new markets. It is positioned to become a core technology defining the next generation of buses, leading public transportation toward a more efficient, economical, and safe future.
