Description

Technical Field

[0001] The utility model relates to the field of bicycle component testing, and more specifically to a PC-controlled frame disc brake seat fatigue testing machine. Background Art

[0002] Disc brakes consist of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking, the high-pressure brake oil pushes the brake pads to clamp the brake disc to produce a braking effect. Disc brakes are sometimes also called disc brakes. They are divided into ordinary disc brakes and ventilated disc brakes. Ventilated disc brakes have many circular ventilation holes drilled on the disc surface, or ventilation grooves cut on the end face of the disc or pre-fabricated rectangular ventilation holes. Ventilated disc brakes use the effect of wind flow to have better cooling and heating effects than ordinary disc brakes.

[0003] The disc brake seat is the connecting and fixing part between the disc brake and the frame. During the riding of a bicycle, the disc brake seat is used very frequently because it is a very important component of the bicycle braking system, which puts high requirements on its fatigue resistance. However, after the production of the disc brake seat, due to the lack of fatigue resistance testing equipment, some inferior disc brake seats are circulated in the market, affecting the braking effect of the bicycle.

[0004] Therefore, a PC-controlled frame disc brake seat fatigue testing machine is proposed to solve some problems existing in the above-mentioned prior art. Utility Model Content
