Fluid Actuated Drum Brakes TRIZ Cases
- Hydraulic Support Legs for Self-Leveling on Uneven Surfaces
Hydraulic pistons use structural load to self-level support legs, then pressure-activated braking locks the structure stable on uneven surfaces.
- Air Brake Operating Cam Geometry for Reverse Braking Noise
Adjusting the cam-to-roller contact direction during reverse braking stabilizes reaction force and cuts air brake vibration and low-frequency noise.
- Radial Drum Brake Lining Retraction With Preloaded Restoring Springs
Preloaded restoring springs fully retract drum brake linings after release, preventing residual grinding torque, wear, and fuel loss.
- Radial Drum Brake Return Spring Layout for Residual Torque Release
Preloaded return springs retract drum brake linings fully after braking, cutting residual grinding torque, wear, and fuel loss.
- Flexible Shaft Locking Clamp for Precise Axial Positioning
A one-piece flexible clamping piece locks a shaft with even friction contact, improving positioning precision without a bulky mechanism.
- Integrated Drum Brake Module With Adjacent Service and Parking Actuators
Adjacent service and parking actuators on one brake holder save drum brake space, simplify assembly, and support self-locking parking brake operation.
- Hydraulic Clamping Element With Thin Membranes for Compact Radial Release
Thin inner and outer membranes direct hydraulic deformation radially, enabling compact shaft clamping with lower space and cost.
- Drum Brake Adjuster With Disc Spring for Parking Force Retention
A disc spring built into the adjuster maintains shoe spreading force during parking while keeping the motor gear unit compact.
- Forestry Winch Belt Brake Regulating Mechanism for Smooth Deceleration
An adjustable dual-actuator belt brake enables gradual load deceleration on slopes while reducing stress on winch components and towed loads.
- Vehicle Drum Brake Device with Internal Motor Nesting
Nesting the motor inside the drum improves water tightness and reliability while reducing overall product size.
- Internal Shoe Brake Actuator Guide Element for Reliable Adjustment
A pivotally mounted adjusting lever interacts with a housing-fixed guide element to convert axial movement into precise pivoting motions.
