Envalior (Düsseldorf, Germany), a global supplier of high-performance engineering materials, has partnered with transmission shift systems company Koki Tecknik Transmission Systems GmbH (Niederwürschnitz, Germany) to develop a new technology for use within the E-powertrain decoupling unit. We provide a shift fork that fits your needs. Koki selected his Envalior's ForTii ACE PPA, which is reinforced with 50% glass fiber, for shift fork applications. This is because this material offers extremely high stiffness up to 160°C, design freedom and maximum wear resistance without the need for additional bushings.
The main objective for Koki's shift fork application was low weight with high stiffness and maximum wear resistance. The company also wanted to reduce the cost of the application compared to heavily machined aluminum parts.
According to Ron Krotwaar, Envalior's advanced development specialist for lightweight solutions, ForTii ACE is a competitive alternative to aluminum components in decoupling units used in E-powertrains and conventional transmissions. It is said to be a material with
“Almost all functions, such as assembly interfaces, gearing, and sensing systems, can be integrated into well-designed components made of fiberglass and thermoplastic composites without the need for additional processes. As a result, potential cost savings can be achieved,” added Martin Wollenberg, Head of Business Development at Koki.
Additionally, with the help of Envalior's CAE services and predictive technology, the two companies will work together to further improve the accuracy of Koki's advanced CAE simulation capabilities to optimize shift fork mechanical performance and geometry for machining. Succeeded. The Koki/Envalior team worked together on anisotropic material behavior and material modeling. Additionally, we shared our knowledge and experience in simulation and interpretation of results. Additionally, Envalior supported his Koki with viscosity measurements.
“The team understood how to capture material behavior and process the results specifically for Envalior's ForTii ACE MX53 material,” says Krotwaar. “Koki and the Envalior team have enabled more robust part performance and design to safety limits. Envalior’s deep materials knowledge and experience with material behavior allows Koki to provide product design, simulation, and tools as needed. We were able to readjust and maximize the performance of the material.”
