Optimisation of the internal shifter for Manual Transmission (F17)

Customer: GM / Opel

Scope of services of RLE:

  • Benchmark, generation of a specification
  • Concept development
  • Feasibility studies
  • Design; calculation
  • Simulation of Kinematics
  • Prototypes (functional model)
  • Patent research
  • Pre-selection of supplier with cost analysis

Special project features:

  • Benchmark: Analysis of existing solutions, compare to the stateof the art solutions
  • Concept study: Preparing various versions and solution steps, feasibility studies
  • Specification: c/o for component groups like transmission case,shift-forks, outer shifting etc.
  • Presentation and final inspection at the customer, definition of the best solution
  • Design of the modified parts, FE-calculation and simulation of Kinematics
  • Handover of documentation, presentation of a prototype an complete transmission

Technical Highlights:

  • Reduction of components for adjustment / interlock mechanism
  • Less tolerance sensitivity
  • Estimated cost savings of approx. 30%, at a gear box which is in production for 28 years
