Axially Engaging Brakes TRIZ Cases

A segmented brake piston seals the spindle and nut assembly from hydraulic fluid without limiting travel or anti-rotation engagement.

Motor shaft angle and current profiles identify brake contact and force behavior, enabling precise sensor-less electromechanical braking.

By nesting the sensor and target inside the brake, this case tracks shaft position without adding encoder length to the motor output shaft.

A centering device aligns the brake caliper and pneumatic brake cylinder while enabling removal without extra wheel-housing space.

An annular extraction chamber with a suction ring, filter insert, and cooling fins captures brake dust while limiting heat damage in drum brakes.

A motor-driven leadscrew, captive nut, and failsafe brake help a pipeline plug hold sealing and position under pressure variation.

A double through-hole caliper flange adds offset fixing points to spread motor loads, reduce vibration fatigue, and improve brake reliability.

A split brake caliper housing isolates the BCU from motor heat and mechanical stress while keeping the electric brake assembly compact.

A unidirectional torque-limited stud separates wear compensation from force gain, simplifying brake structure and improving reliability.

A unidirectional torque limiter separates wear compensation from force gain in an electromechanical brake, reducing interference and structure complexity.

A stopper constrains ball screw retraction and brake pad separation to prevent wear, collision, and sticking while easing brake maintenance.

A combined radial and axial flux eddy current brake raises aircraft wheel braking torque without the weight and bulk of larger magnets.

A tuned raceway radius-to-ball diameter ratio boosts brake force transmission while limiting Hertzian pressure and preserving smooth return.

A ball-and-race torque limiter enables asymmetric piston travel in electromechanical brakes while keeping pad load uniform and wear lower.

A nested sensing ring with bending elements and strain gauges measures brake force inside the caliper, saving space while improving reliability.

Axial insertion joins the electric actuator to the bracket in one motion, improving assembly while restricting rotation and reducing brake size.

A drive gear links two screw-nut brake mechanisms to raise clamp force, spread stress, and save axial space in electromechanical brakes.

An integrated anti-rotation boss and recess layout shortens brake caliper axial length while preserving sealing and simpler machining.

Hydraulic piston preloading followed by mechanical locking keeps parking brake force without electrical power or continuous hydraulic assistance.

A shared support shaft keeps dual output members coaxial in a disc brake motor gear unit, improving gear meshing, assembly, and reliability.

A self-locking secondary motor and gear path releases residual brake clamping after EMB motor or control failure, preventing wheel drag.
