Chassis components
Always safe and sound
Subframes, twist-beams, links steering arms and knuckles; whatever your chassis requirements, BENTELER provides you full-service support. In front subframes alone, we currently produce more than eight million products in series production per year. For all vehicle segments. In 20 plants worldwide. That’s almost one in every ten vehicles built! All around the world, our customers know that they can count on us. Because we deliver consistent products on time, on cost and at the right quality.
As metal processing experts, we offer unmatched material expertise. Whether it’s in aluminum, steel or hybrid, we’re in our element. Plus, we offer a wide range of technologies to suit each individual requirement: from MAG and spot welding to press-in operations, complex stampings and hydroformed components. Whatever your needs, we actively support you. From build-to-print to full design and development.
Complete chassis systems, all under one roof
Front subframes
Quiet and low on vibration
We supply crossmembers and subframes to a number of manufacturers. These are primarily high-strength, low-alloy (HSLA) steels with corrosion protection to customer specification, i.e. pre-zinc coated, e-coat, hot-dip galvanizing or waxing. Our aluminum-FRP hybrid concept helps reduce noise and vibration while significantly decreasing weight compared to one-piece casted designs.
Rear subframes
Strong and functional
Our range of multi-link rear subframes in steel and aluminum feature the latest forming and joining technologies. Our U-O-forming technology for side and crossmembers offers weight and cost saving potential while optimizing strength and stiffness. Our hydroformed subframes fulfil complex functional requirements and offer excellent robustness and corrosion resistance.
Twist-beams
High quality and durable
Thanks to our global presence, we offer customers consistent material characteristics and quality to customers around the world. We provide complete definition and optimization of complex kinematic and elasto-kinematic behaviors, encompassing all individual parts, including torsion profiles, body bushes, etc. Our full-service solutions cover all requirements. Whether its strength and fatigue related – including simulation, prototypes and testing.
Links / Arms / Knuckles
Lighter and stiffer
BENTELER produces more than 10 million control arms per year. These, together with our knuckles are used in platform axles by a range of manufacturers. Materials include UHS steels such as CPW800 or FB780. The BENTELER aluminum system uses stretch bending and additional forming to provide high performance spring links from aluminum extrusions. These offer weight reductions of up to 35 % with a 50 % increase in stiffness compared to conventional materials.
