Wheel Based Transmission TRIZ Cases
- E-Bike Drive Assembly With Overlapping Freewheels for Compact Torque Transfer
Coaxially overlapping freewheels shrink e-bike drive width while maintaining reliable torque transfer and a lower Q-factor for rider comfort.
- E-Bike Drive Arrangement With Overlapping Coaxial Freewheels
Coaxially overlapping freewheels combine motor and pedaling torque paths to shrink e-bike drive packaging while maintaining efficient transmission.
- Centrifugal Clutch Bicycle Transmission for Compact 3-Speed Shifting
A centrifugal clutch and composite planetary gear ring enable automatic 3-speed bicycle shifting in less space with lower weight and cost.
- E-Bike Power Module Axial Layout for Compact Torque Sensing
An axial motor-reducer layout cuts e-bike module thickness while a serial torque sensor improves pedaling torque measurement accuracy.
- Bottom Bracket Gear Layout for Compact Mid-Drive E-Bikes
A speed-up input stage and freewheel shrink the bottom bracket gearbox, fit a mid-drive motor, and improve e-bike weight distribution.
- E-Bike Drive-Brake Assembly With Planetary Rotor Transmission
A planetary link between the disk motor rotor and drive shaft lets an e-bike wheel use a high-speed motor in limited space while improving energy recovery.
- Modular E-Bike Drivetrain With Clutch for Better Power-to-Weight
A clutch-linked modular e-bike drivetrain lets pedals and motor drive together while improving serviceability and power-to-weight.
- Bottom Bracket Planetary Gear Layout for Compact E-Bike Drives
A one-piece freewheel carrier and planetary gear set fit the e-bike bottom bracket, saving pedal-shaft space while transmitting pedal and motor torque efficiently.
- Bicycle Crank Assembly With Rotating Arm for Higher Torque Stability
A rotating arm, gears, and roller-supported axle raise bicycle crank torque while preserving ergonomics, transmission stability, and service life.
- Bicycle Gear Shifting Control With Two-Switch Synchro-Shift
Two switches trigger synchro-shift and single-device shifts, reducing cockpit clutter while improving gear change response.
- Epicyclic Bicycle Gear Assembly for Compact High-Torque Shifting
Interconnected epicyclic gear sets and integrated clutches create a lighter, more compact bicycle transmission that handles high torque and shifts smoothly.
