Gearing Control TRIZ Cases
- Synchronous Motorcycle Transmission with Dual Centrifugal Clutch
A synchronous motorcycle transmission uses a dual centrifugal clutch to engage fixed gear ratios automatically.
- Infinitely Variable Transmission Clutch Control for Work Machine Traction
Adjusting clutch slip speed and input output ratios minimizes power loss from wheel spin while maintaining constant tractive effort at low ground speeds.
- Gearbox Control Unit Prevents Double Gear Shifts
A gearbox control unit bars manual gear changes during automatic shifts to stop unwanted double gear selections.
- 9-Speed Transmission Form-Locking Shift Element Sensor Control
A sensor detects form-locking shift element states in 9-speed transmissions to generate precise disengagement control signals.
- Vehicle Control Device for Sensor Abnormality Fail-Safe
A vehicle control device determines shift position sensor abnormalities to enable safe starting under specific braking conditions.
- Pneumatic CVT Actuator Control for Ratio Adjustment
A pneumatic actuator adjusts CVT transmission ratios by connecting to vacuum or pressure sources based on engine speed.
- Machine Acceleration Control via Virtual Gear Downshift
A control system determines a virtual gear to downshift the transmission upon exiting a grade.
- Range Switching Device Solving Valve Sticking with Single Solenoid
A range switching device uses a single solenoid valve to regulate source pressure for parking actuation.
