LANDSKRONA, Sweden – At next month’s IAA (International Automobile Exhibition) in Frankfurt, Haldex will disseminate pre-production information about its new EMB, electromechanical brake, which is not due to enter high-volume manufacture until 2025 or later.
In terms of the value proposition, the EMB system is much simpler than the existing pneumatic system, in that it is entirely electric controlled and actuated from the brake pedal to the wheel-end.
In EMB, there are about half as many components, which makes the entire system lighter and simpler to produce.
Because it has no need for a compressor, EMB supports up to 90-percent energy savings, compared to existing conventional pneumatic systems on trucks and buses, due to higher efficiency.
There are also noise benefits, as compressors and valves are typically noisy when charging and venting. EMB also includes an electric parking brake function as part of the integrated wheel end design.
Haldex also claims that the system offers a reduced stopping distance, thanks to better and more precise control of the wheel speed compared to pneumatic systems when braking.
Over the next few years, Haldex will continue to develop, test and validate the technology with simulations and physical units in readiness for industrialization.
Says Haldex Executive Vice President, Product and Technology, Fredrik Seglö: “Given the huge development of hybrids, and now the transition in industry to full-electric vehicles, we believe the move is justified for full electric brake transmission, not just for the control signals but also for the wheel end actuation itself. That’s the natural next step in the future.”
The Landskrona, Sweden-based company’s IAA exhibit will feature some of its newest, as well as most significant braking products including the ModulT air-disc brakes; EB+ 4.0 remote EBS platform, and LifeSeal+ actuators.
