A locking ball replaces fragile shear-loaded pins in a spring brake release mechanism, improving durability, compactness, and assembly.
A pin indicator linked to the running nut shows parking brake status externally while simplifying spring brake cylinder manufacturing.
A multi-spring parking brake actuator cuts installation space while maintaining braking force despite brake wear in commercial vehicles.
A service brake cylinder nested inside the spring brake cylinder reduces air use, saves space, and limits force interference.
Flexible rim segments snap over the housing flange to replace clamp rings and crimping, cutting assembly time and easing diaphragm replacement.
A one-piece diaphragm and reduction ring cuts leak paths while tuning effective area and force transmission in pneumatic brake cylinders.
A dual-material piston tube pairs a low-friction polymer guide with steel support to simplify spring brake actuator manufacturing and torque transfer.
A central embossment and guiding features stiffen the spring seat, keep the brake spring aligned, and reduce release noise.
A recessed release bolt secures the locking pin by press fit, avoiding precise hole drilling and cutting brake cylinder assembly cost.
Segmented connection rings prevent unauthorized disassembly while reducing zinc coating costs.
A glass fiber reinforced plastic adapter plate replaces metal components in heavy vehicle brake actuators.
An internal ventilation conduit links the spring and non-pressure chambers, eliminating complex breather valves and external piping.
An integrated bearing mediates reciprocation between the pressure plate and actuator tube, preventing thread wear on caging bolts during spring containment.
