Development of a new rear axle – DAF Trucks

Objectives:

• To achieve 15-20% weight reduction of the rear axle.
• To achieve 30-40% reduction of friction losses.

M2i project:

2 Proto axles produced: 17% weight gain (65kg) and 28% reduction of losses (~1% Fuel Efficiency)

Implementation in Testing phase

• New axles include design changes proposed by M2i
• Target CO2 reduction: 30kton CO2/yr

Industrial benefits:

• Reduction of significant losses in rear axle (3% fuel efficiency)
• Complex interdependent design
• Many conventional manufacturing processes
