Vehicle Energy Devices TRIZ Cases
- Hollow-Shaft Wheelset Auxiliary Drive With Integrated Planetary Gear
A hollow-shaft auxiliary drive integrates an E-machine and planetary reduction gear to enable compact wagon shunting with lower drag torque.
- Cableway Operation With Symmetric Coupling and Flexible Capacity
Self-propelled cableway transport units couple symmetrically to the haul rope while vehicle counts adjust to passenger demand and cut operating complexity.
- Magnetic Rotor Rail Energy Harvesting Without Train Retrofit
Trackside magnetic rotors harvest power from passing ferrous rail cars, avoiding vehicle retrofit while converting train motion into electricity.
- Wheelset Bearing Sensor Layout Using a Claw-Pole Generator
A claw-pole generator powers modular wheelset bearing sensors through a common line, saving space and supporting continuous monitoring.
- High-Speed Railway Bogie With Axle-End Generator for Wear Reduction
This railway bogie combines axle-end generation, rubber suspension, and dampers for 160 km/h stability and reduced wheel-rail wear.
- Modular Wheel Energy Recovery Apparatus for Twin Axle Vehicles
Segmented rotor and stator units mount independently into wheel cavities, eliminating deep axle integration that complicates maintenance.
- Rail Vehicle Electric Machine Regenerative Braking and Power Generation
Vehicle-mounted electric machines provide regenerative braking and onboard power generation, eliminating external deceleration conveyors.
- Rail Vehicle Generator System Integrating Friction Wheel Rotor
Integrating a friction wheel rotor on the wheelset end cap eliminates complex design modifications required for standard generator systems.
- Wheelset Bearing Housing Position Detection Device
Integrating a GPS receiver and bearing-free hub generator within the wheelset bearing housing protects tracking equipment from theft and environmental damage.
- Cable-Drawn Vehicle Energy Supply via Generator and Store
An onboard generator supplies power at high speeds while a smaller energy store handles acceleration, reducing system complexity.
- Axle Generator With Internal Magnets For Railway Wagons
Axle generator with internal magnets resolves torque and dirt protection trade-offs for railway wagons.
- Rail Tamping Machine Regenerative Vibration Drive
A rail tamping machine uses a regenerative electric intermediate circuit to power vibration drives directly from bogie braking energy.
