Brake-by-wire: enhanced stopping power.
Daniel Triolo, Lead Key Account Manager at Datwyler, looks at brake-by-wire technology, its composition, and the many benefits it can deliver to the mobility sector and its customers.
High-performance components for brake systems
Meeting the highest safety standards, Datwyler’s system-critical brake components are characterized by mechanical-dynamic stability, resistance to high and low temperature and media for maximum durability.
Components for brake systems cover numerous applications for actuation such as vacuum brake booster and EHB (electrohydraulic brake booster). Datwyler is also a global leader for components used in foundation, EPB (electric parking brake), as well as in future-oriented technologies like brake-by-wire.
Co-engineering for future brake technologies
The brake technology has evolved and will continue to do so. Thanks to close and trustful engineering relationships with market leaders over decades, Datwyler is the right partner for future-oriented brake systems and already involved in numerous projects. Contact Datwyler at an early stage of your development project, and obtain the best-in-class support of Datwyler engineers to achieve mutual success.
With the supply of system-critical components for brake systems, Datwyler makes an important contribution to the road safety worldwide.
Advanced materials as a key factor
Thanks to Datwyler’s strong competence in surface technologies, adhesion, and materials in elastomer/ metal and elastomer/plastic including LSR (liquid silicon rubber) and TPL (thermoplastic), Datwyler is able to develop materials, which meet customer-specific requirements and needs. Electrohydraulic brake systems, for example, impose special requirements on abrasion resistance, cleanliness categories, and the precision of sealing solutions in production.
Among other things, the elastomer components in modern brake control systems must resist high-frequency, dynamic-mechanical loads under high pressure, and simultaneously guarantee safety over the lifetime of a vehicle.
Key Applications
New technologies like electrohydraulic booster, electric parking brake and brake-by-wire are driving the transition to electrification in brakes. Datwyler is committed to accompany its customers during the whole length of this transition.
Datwyler can support you in the development of sealing components for complex brake systems. Thanks to our know-how in material development and to the use of safe and reliable high-performance materials, you can benefit from Datwyler’s expertise in system-critical engineered elastomer solutions. Learn how Datwyler can support you solve your engineering challenges in single and multi-component polymer brake applications:
Brake-by-wire
Brake-by-wire technology is the ability to control brakes through electrical means. It can be designed to supplement ordinary service brakes (dry-wet) or it can be a standalone brake system (dry-dry).
Electro Hydraulic Booster
With an electrohydraulic booster, electric actuation of the brake is achieved which in turn reacts fast and generates a lot of friction power. The electrohydraulic booster is driven through electrification, ADAS, AD. Benefits are the increased safety, reduced size and weight as well as the multifunctionality.
Electric Parking Brake
By clicking on a button, the driver activates the holding mechanism in an electric parking brake (EPB) and as a result, the brake pads are electrically applied to the rear wheels. This is obtained by an electronic control unit (ECU) and an actuator mechanism.
Vacuum Booster
The vacuum booster assists the braking force applied by the driver. The vacuum booster is placed between the master cylinder and the braking pedal. Once the driver stops operating the pedal, the air valve closes again and allows for more air for continued boosted braking.
Datwyler’s advancement in sealing applications enables the use of sensors for streamlined production and tracking.
The traceability of parts via smart sealings – for example with embedded sensor technology – could expedite a product recall if required, minimizing the safety impact and potential reputational damage a brand could suffer. Sensors could also be used for predictive maintenance purposes in the future, along with providing solutions relating to authenticity that could combat counterfeiting and ensure parts are from the original manufacturer.
Not least, Datwyler’s sealing solutions designed and co-engineered specifically for purpose in these new applications will provide the highest levels of quality and integrity, ensuring the safe operation of the brake system throughout its lifetime.
Key products
Components for brake systems include seals and dampers like dust boots, bushings, primary and secondary seals, O-rings, piston seals, and diaphragms. Materials include EPDM, FKM, SBR, HNBR, AEM, and silicon materials.
Damping disc
The damping disc is made of EPDM and aluminum and is used for the electro-hydraulic booster as a noise damper.
Guide Pin Excluder
Sealing boot for caliper made of EPDM, which avoids dust and water entering.
Piston Seal
Sealing for caliper piston made of EPDM.
Diaphragms for truck air brake systems
Diaphragms for air brake systems are manufactured according to strict specification and performance tests. The products are made of fabric reinforced rubber layers.
Diaphragm for brake booster
Safety items like diaphragm are usually made of EPDM or SBR compounds and used in the brake booster.
Bushings
Datwyler manufactures bushings with and without inserts. Developing applications for passenger vehicles and commercial vehicles.
