Gear shift force test stand
Accurate force measurement for gear shifts: ergonomic, safe, automated
- Type: development test stand, component test stand, quality assurance
- Device under test: car manual transmission
- Test task: measurement of shift force during gear changes
Manual transmissions are still common, in small cars, sports cars and development projects with hybrid components. For vehicle manufacturers, the transmission has to work, and it has to feel right to the driver. Too much shift force spoils the driving experience, tires the driver and leads to operating errors.
In development, quality assurance and type approval of car manual transmissions, measuring the required shift force is therefore a key test point. What's needed is a repeatable, documented record of the force curve over the full shift travel, at variable speeds and with changing shift profiles.
