The AxTrax 2 LF is developed specifically for:
18-metre articulated buses
11-metre city buses
These buses are commonly used in urban public transport systems, where low-floor design ensures easy passenger entry and exit.
The AxTrax 2 LF replaces the conventional engine, transmission, and axle assembly with a single integrated unit.
One of its key advantages is that it uses the same installation space and mounting points as conventional low-floor axles. This makes it easier for bus manufacturers to integrate the system without major design changes. It also ensures backward compatibility, simplifying upgrades from older platforms.
The electric axle is available in two continuous power variants:
260 kW
360 kW
It delivers a peak torque of up to 36,800 Nm, ensuring strong performance in demanding city conditions.
The 360 kW variant offers more than 25% gradeability, allowing 18-metre articulated buses weighing up to 30 tonnes to climb steep inclines using a single driven axle.
The AxTrax 2 LF integrates:
Two permanent magnet synchronous hairpin motors
Two independent 800-volt silicon carbide (SiC) inverters
A dedicated electronic control unit (ECU)
It also features an integrated oil cooling system, including a pump and heat exchanger within the axle. This setup manages both temperature and lubrication efficiently.
According to ZF, this configuration reduces energy consumption compared to the previous generation of low-floor e-axles in typical urban operations.
The system supports:
6x2 drivetrain configuration
6x4 drivetrain configuration
It is compatible with multiple zero-emission platforms, including:
Battery-electric buses
Hydrogen fuel cell buses
Trolley buses
This flexibility makes it suitable for a wide range of city transport applications.
The AxTrax 2 LF includes advanced software functions such as:
Regenerative braking
Torque vectoring
Hill hold
Cruise control
Axle condition monitoring
Over-the-air (OTA) software update readiness
ZF states that the system complies with ISO 26262 functional safety standards and meets regulatory cybersecurity requirements, ensuring safe and secure operation.
ZF offers the axle with the following options:
Air suspension
Wheel-end solutions
This modular package allows OEMs to configure drivetrains according to different load capacities, terrains, and operating needs.
Akash Passey, President of ZF Region India, highlighted that compatibility with multiple zero-emission platforms is a key value for OEMs. Paramjit Singh Chadha, Senior Vice President of Commercial Vehicle Solutions for ZF Group in India, noted that the integrated architecture covering propulsion, braking, suspension, and electronics helps reduce vehicle development time.
With deliveries beginning in 2026, the AxTrax 2 LF marks an important step in India’s electric mobility journey. By combining performance, efficiency, safety, and flexible integration, ZF India aims to support city transport operators and manufacturers in accelerating the shift toward cleaner and smarter public transport systems.
