AI Technical Summary
Existing speed limiting devices are large, heavy, and complex in structure, which makes unpowered gliding equipment prone to rear-end collisions on long, gentle slope sections. In addition, the high installation precision requirements of existing devices limit their application in miniaturized equipment.
The speed-limiting wheel device utilizes the coordinated operation of a turntable, slider, wedge block, brake disc, and spring. The radial sliding of the slider is converted into the axial movement of the brake disc through the inclined surface structure of the wedge block, achieving lightweight and miniaturization. Centrifugal force is used to automatically trigger braking, ensuring sufficient braking force.
While ensuring braking force, the overall size and weight of the speed limiting device are significantly reduced to prevent safety accidents caused by excessive speed, and to improve equipment operating efficiency and tourist reception capacity.
