Braking Drums TRIZ Cases
- Triboelectric Friction Brake Charge Recovery Circuit
Brake-pad electrodes harvest triboelectric charges during friction, using a simple collection circuit to improve braking energy recovery reliability.
- Heavy Vehicle Drum Brake Wear Sensing via Cross-Shaft Rotation
A cross-shaft sensor tracks brake shoe and drum wear in heavy vehicle drum brakes, enabling condition-based maintenance and less downtime.
- Steel-Shell Brake Drum Refurbishing by Centrifugal Iron Relining
Superheating and centrifugal iron relining restore worn steel-shell brake drums for reuse, cutting waste, cost, and carbon footprint.
- Brake Drum Sealing Ring for Fine Particle Containment
A torus-shaped sealing ring traps brake wear particles inside the drum, cutting airborne fine dust while keeping maintenance simple.
- Sealed Drum Brake Chamber With Air-Permeable Dust Filtration
An enclosed drum brake chamber uses air-permeable filter walls and pressure compensation to retain brake dust while allowing airflow.
- Composite Brake Rotor Press-Fit Joint for Torque and Heat Transfer
A press-fit undercut joint separates fixing from torque transfer in a composite brake rotor, improving stress distribution and heat dissipation.
- Composite Brake Rotor Coating for Low-Weight Thermal Stability
An aluminum alloy core with thermal barrier and wear-resistant layers cuts brake weight while protecting against heat and friction.
- Drum Brake Pivot Lever Deflection for Wheel Cylinder Durability
A deflectable pivot lever absorbs brake drum contraction forces, lowering wheel cylinder stress while maintaining brake shoe pre-load.
- Removable Drum Brake Dust Trap for Simple Particulate Capture
An annular trap seated in a drum groove captures brake dust while rotating with the drum, enabling simple removal and controlled disposal.
- Drum Brake Airflow Path for Stable Shoe-to-Drum Clearance
An internal airflow path keeps brake shoes separated from the drum to prevent partial contact, cut drag torque, and support cooling and dust removal.
- Drum Brake Flap Mechanism for Constant Shoe Clearance
Centrifugal force bends a flap to rotate a joint and keep brake shoe clearance constant, reducing drag torque, wear, and wasted drum space.
- Shaped Brake Shoe Friction Structure to Prevent Lateral Migration
A flange-matched friction structure keeps the brake shoe aligned on the wheel tread, preventing lateral migration and uneven wear.
- Segmented Drum Brake Structure for Lower Vehicle Weight
A split drum uses a lightweight body and durable friction part to cut brake weight while preserving wear resistance and fuel efficiency.
- Brake Drum Cooling Conduits for Controlled Thermal Distribution
Varying thermal conductance across brake drum sections controls local cooling, keeping braking surface temperature in an effective range.
- Composite Brake Rotor Press-Fit Layout for Lower Pin Shear
A separate press-fit and fixing interface spreads brake loads, cuts pin shear stress, and improves heat dissipation in composite rotors.
- Brake Drum Dust-Guiding Grooves for Low-Emission Dust Collection
Dust-guiding grooves channel brake dust to an integrated collector, cutting emissions without adding a heavy dust-tight casing.
- Annular Drum Brake Dust Trap for Easy Removal and Disposal
A removable annular trap seated in the drum groove captures brake dust during rotation, making disposal easier and limiting particulate escape.
- Aluminium Drum Brake Structure for Heat Dissipation and Contact Flexibility
A segmented aluminium drum wall adds heat-dissipating mass away from the transition area to improve cooling, wear, and shoe contact.
- FRP Brake Drum Structure for Lower Weight and Heat Stability
Using fiber-reinforced plastic with tailored fiber layers, this brake drum cuts unsprung mass while preserving strength and heat stability.
