Bosch adds rigid eAxle and automation hardware for electric trucks
Bosch is expanding its commercial-vehicle portfolio with a rigid electric axle for 18- to 49-tonne trucks, alongside high-voltage thermal management and automation systems.
- 18–49 tonnes
- up to 99%
- 800 V
What Happened
Bosch is showing a Rigid eAxle for electric heavy commercial vehicles at IAA Transportation. The unit combines the electric motor and transmission in one axle and is aimed at trucks from 18 to 49 tonnes.
18–49tonnes
Vehicle weight range stated by Bosch for the Rigid eAxle.
Bosch says the axle can use its silicon-carbide inverters, which the company rates at up to 99 per cent efficiency. It is also presenting an 800-volt blower module intended to cool electric commercial-vehicle components on demand while limiting the energy used by thermal management.
- A central Vehicle Integration Platform for software-defined commercial vehicles.
- Driver monitoring integrated into the left screen of a digital side mirror.
- The fully electric ServoE steering system for assisted and automated functions.
- Fuel-cell systems and hydrogen-engine components alongside battery-electric hardware.
Bosch has not disclosed the Rigid eAxle’s output, mass or quantified weight saving compared with a central electric drive. The company is positioning the unit within a broader commercial-vehicle technology package spanning propulsion, cooling, steering, computing, connectivity and fleet support.
Why this matters
The integrated axle gives truck makers another way to package the electric motor and transmission in heavier vehicles, while Bosch is tying the hardware to silicon-carbide inverters, thermal controls and software-defined vehicle systems. The supplier has not yet published performance or weight-saving figures for the axle.
