Drum Brakes TRIZ Cases

A spring-biased electromagnetic brake built into the hub motor holds the sled at standstill without separate brake hardware and engages on power loss.

Gravity-based angle sensing on the brake actuating element tracks lining wear and brake function without costly sensors on each lining.

A spring-biased brake inside the hub motor eliminates separate parking hardware while holding a delivery sled at standstill when power is lost.

Relative movement between the adjuster and shaft is sensed to track drum brake friction wear without disassembly or manual inspection.

Estimated drum temperature sets brake lining clearance after release, preventing thermal brake drag and stabilizing braking.

By sensing adjuster-shaft movement instead of the full brake stroke, this case tracks drum brake friction wear with fewer sensors and higher precision.

A solenoid pawl and press-slip-fit sleeve brake a permanent magnet generator to zero speed after short-circuit faults.

Motor current monitoring stops cable-pull brake release at the right point, avoiding residual torque while keeping release fast and reliable.

Offset brake lobes spread wheel-tread contact zones to limit hot spots, reduce thermal distortion, and extend wheel life.

An actuating ring drives segmented lining carriers radially to limit self-energization, improve wear uniformity, and expand drum brake use.

Distance sensing between the brake arm and drum enables real-time brake wear monitoring and warning signals before conveyor brake failure.

A pivoted brake with spring bias and lever action raises static friction on the roller to suppress elevator bounce and vibration.

Movable magnets and a non-ferrous flywheel disc deliver smoother resistance changes with less wear and more accurate rider energy measurement.

Non-contact magnetic or capacitance sensing tracks brake lining wear continuously, avoiding damaged contactors and enabling timely replacement.

Non-contact magnetic or capacitance sensing tracks brake lining wear continuously, avoiding damaged contactors and reducing maintenance downtime.

An axial actuating pin with an inclined contact surface simplifies pawl switching, cuts wear, and keeps the freewheel compact and reliable.

A pivoting brake with spring bias boosts static friction at the roller, limiting elevator bounce and vibration during loading and unloading.

A permanent magnet in the drum brake air gap captures escaping brake dust while preserving ventilation and cooling for stable magnet performance.

An intermediate ring removes wrap spring play in a disc brake adjustment sleeve, cutting air gap, response time, and braking delay.

Segmented magnets and a load cell smooth indoor cycle resistance changes, reduce brake wear, and improve energy measurement accuracy.

A retrofit grapple brake uses external force and friction to stop timber rotation safely while avoiding costly swivel joints.

An intermediate ring removes play between the guide sleeve and wrap spring, cutting pad reaction time and improving disc brake force.

Cup-shaped deep-drawn features join the support grid without weakening the backplate, improving brake shoe rigidity, wear, and service life.

An electric actuator unit drives drum brake shoes via a motor, gear-set, and pull rod assembly.

A sensor monitors the distance between the brake magnet armature and housing to detect wear before contact voids braking capacity.

Axle wrap weld window enables cam bracket mounting that reduces stress concentrations and improves suspension durability.

Electric wedge locks drum brake segments via lever pivot, eliminating high manual handbrake effort.

A gantry binary synchronization block-type brake uses a dual releaser to push braking arms outward synchronously.

Segmented metal or plastic connector parts form a circulating groove to flush salt residues from boat trailer brakes without modifying the plate structure.

Elevator brake uses eccentric adjustment elements to set the air gap between the brake block and drum.

Axially guided ring magnet armature replaces bulky hydraulic systems to generate high braking forces with minimal installation space.
