Hydraulic control unit for AT and CVT
Customer: ZF Friedrichshafen
Scope of services of RLE:
- Installations study, definition of assembly parts
- Layout according to hydraulic diagram and valve –specification
- Parametric design acc. functional and manufacturing (die cast)
- Detailing and tolerancing for serial parts
- Tolerance analysis of valve/control edges
Special project features:
- The hydraulic diagram including functional description has been coordinated with the customers ZF resp. Ford.
- Definition of minimum numbers of design parameters, layout
- Definition of control edges, parameterized CAD-construction, to simplify design modifications
- Generation of documentation incl. tolerance analysis of control edges
- Design and specification of hydraulic diagram
- Modelling and inspection of functions with programs as: Matlab/ Simulink, AMESim
- CAD-Engineering: responsibility at RLE (from concept up to serial parts)
- Parameterized construction according to a self developed method, which simplifies later modifications and the development of gear bodies of the same family automatically. Now basis for ZT internal standard!
