Spring Brake Actuator Stopper for Torque Feedback

The patent implements a feedback mechanism through a stopper that contacts the housing at a predetermined position during spring compression. This contact provides haptic feedback to the operator, signaling that the spring has reached its maximum compression state and no further torque should be applied. This solves the problem of operators not recognizing the end position due to the steep torque curve of half-release bolts.

The stopper mechanism performs preliminary anti-action by preventing excessive torque application before damage can occur. The stopper is positioned to engage with the housing exactly when the spring reaches maximum compression, creating a mechanical barrier that stops further compression and protects the system from damage.

The stopper provides clear haptic feedback through its contact with the housing, creating a noticeable change in torque resistance that alerts the operator to stop rotating the release bolt. This solves the recognition problem by providing tactile information that overcomes the difficulty of detecting the end position on steep-torque bolts.

The stopper acts as an intermediary element between the release bolt mechanism and the housing. It mediates the force transmission by providing a controlled contact point that prevents direct transmission of excessive torque to the vulnerable components (bolt, running nut, housing), thereby protecting the system while still allowing operator control.

The stopper provides mechanical feedback through haptic contact with the housing, giving the operator clear information about the spring's compression state. This information transmission is achieved through a simple mechanical contact that does not require complex electronic or mechanical systems, thus providing end position indication with minimal added complexity.

The stopper mechanism is self-indicating through its haptic feedback, eliminating the need for additional indicators, gauges, or complex signaling systems. The operator receives direct tactile information from the stopper's contact with the housing, allowing the system to inform the operator of the end position through its own operational characteristics rather than requiring separate indication systems.
