Axle-Box Lubrication TRIZ Cases
- Gangway Bellows Convolute With Sliding Overlap for Flexibility
Two overlapping inner-layer pieces slide within the gangway bellows convolute, reducing stiffness and simplifying manufacture and assembly.
- Multi-Panel Gangway Sidewall for Opposite Car Rotation
A segmented gangway sidewall uses movable central and side panels to stay stable and controllable when connected cars rotate in opposite directions.
- Articulated Vehicle Side Wall Cladding for Constant Passage Width
Curved guides and pivot arms let articulated vehicle side wall cladding absorb cornering motion while preserving interior space and clear passage width.
- Rail Vehicle Grounding Through Corrosion-Resistant Bolted Contacts
Bolted conductive contact elements ground the rail vehicle superstructure through the frame, avoiding theft-prone cables and corrosion issues.
- Bus Body Insulation With Aerogel Panels and Multi-Glazed Windows
Layered aerogel and melamine insulation with multi-glazed windows cuts bus cabin heat loss without major weight or cost penalties.
- Articulated Cable Support Structure for Vehicle Misalignment
Flexible laminar joints and U-shaped cable holders keep articulated-vehicle cables aligned, absorb stress, and reduce repair-prone damage.
- Gangway Tunnel Bellows With Passenger Supports for Curved Car Movement
Flexible bellows with localized ischial and dorsal support areas improve gangway comfort in articulated vehicles during curved car movement.
- Bellows Vulcanization Bonding to Eliminate Sewn Seams
Vulcanized adhesive bonding joins bellows blanks without needle holes, blocking moisture ingress while cutting seam-forming time and cost.
- Train Bellows Auto-Latching for Faster Coach Coupling
Automated bellows latching and coupler locking cut manual train coach uncoupling effort and support flexible train reconfiguration.
