· EV Transmission

Electrified transmissions are subject to several challenges and requirements.

A combination of international regulations and consumer expectations is driving the demand for reduced noise on all drivetrain components.

Further demand is driven by the growing trend towards EVs and HEVs, where noise from ICE is intermittent or no longer present, and the contribution of transmission noise to overall vehicle noise becomes dominant.

What is true is that the number of gear wheels is significantly reduced in electric vehicles due to the use of one or two-speed reducers instead of the classic manual or twin-clutch gearboxes. In return, these are loaded with torque and RPM’s not previously found in high-volume production.

The other big shift in the automotive industry, the one towards automated driving, is not setting off any alarm bells for gear manufacturers, either. The idea of self-driving cars is currently capturing the industry’s attention, and while it is actually a fascinating trend to follow, X a computer behind the wheel instead of a person is not likely to affect the gears side of the industry too deeply.

DESCRIPTION

In order to meet the current technical requirements, that have become more stringent for the above-mentioned reasons, Marposs can provide a wide range of products and customized applications dedicated to the process control and quality check of the transmission and its components:

  1. Thermal process monitoring for die-casted components (TTV)
  2. Process monitoring during cutting, hobbing and grinding operations 
  3. Hard gauging and mechanical fixtures for quality control 
  4. Hand-held gauges for off-line measurement of prismatic parts 
  5. Non-Destructive (ND) Eddy Current testing to verify surface defects 
  6. In-line and off-line gear measurement (M62 Product Line)
  7. Flexible off-line gear measurement (M62 Flex)
  8. Optical gauges for dimensional checks on transmission shafts and transmission components 
  9. Noise, Vibration and Harshness (NVH) testing of individual gears
  10. Air Leak Testing in pressure decay
