Actuators Used in Braking Systems
Learn why the world’s leading manufacturers of electric braking systems trust Envalior thermoplastic materials for high-performance gears and actuation systems.
Traditionally, clutch and accelerator pedals have been made from polyamide 6, while brake pedals have typically remained metal due to the high load requirements. However, Envalior has managed to significantly reduce the weight and cost of brake pedals by using their proprietary Akulon and Durethan PA6 materials in combination with advanced hybrid technologies.
For conventional brake pedals that activate a vacuum brake-booster mechanically, Envalior has successfully applied their plastic metal hybrid technology. Plastic metal hybrid pedals run in series production based on overmolding a deep-drawn sheet metal profile and afterwards joining this open profile with a metal top layer to achieve a hollow profile in the final part.
Applying this technology maximizes the mechanical performance while reducing weight to a minimum. In addition, for ultra-lightweighting, overmolded thermoplastic composite solutions have been commercialized, offering the design flexibility of injection molding and the high performance of thermoplastic composites for heavily loaded areas.
In e-Braking (brake-by-wire) systems, Envalior's PA6 materials and comprehensive design expertise have enabled the development of fully plastic injection-molded solutions. These innovations maximize both weight and cost efficiency.
"Durethan® is the trade name for our range of engineering thermoplastics based on polyamide 6 and polyamide 66. These polyamides are partially crystalline thermoplastics which offer an ideal combination of properties, especially for technical applications. They provide high mechanical strength and stiffness, good dielectric properties, high resistance to both heat and chemical attack, and good friction and wear properties."
"Akulon® is our family of high performance polyamide 6 and polyamide 66 materials, used by customers across the world in applications ranging from automotive, electronics & electrical, to furniture and packaging."
"We offer Akulon® grades for injection molding, blow molding and extrusion (including barrier film, stock shapes, convoluted tubes, and mono and multi filament)."
"In molded parts the material offers an excellent balance of easy design and processing with outstanding mechanical properties over a wide temperature range and in diverse conditions. Meanwhile for extrusion the strength, resilience and easy processing of Akulon® sets the market standards."
