Description

Technical Field

[0001] This utility model relates to the field of racing simulator technology, and in particular to a servo electric pedal structure applied to racing simulators. Background Technology

[0002] Existing racing simulators use springs or hydraulic structures to provide resistance. Spring structures are prone to loosening, and hydraulic structures are prone to oil leakage. Furthermore, they cannot simulate the force feedback provided by ABS to simulate real braking vibrations. Racing pedals provide braking resistance through springs and hydraulic cylinders, which are based on the compression of the mechanical structure itself. However, the resistance level cannot be set according to different user preferences. Existing racing simulators use bushings or hydraulic piston rod sliding structures for their pedals. These structures are unstable, prone to loosening, and wear, resulting in high noise levels. Summary of the Invention
