Abstract

The invention relates to an automatic centering device, a brake caliper unit, a limit alarm method and an installation method. The automatic centering device includes a first mounting seat assembly; a second mounting seat assembly, and the first mounting seat assembly Symmetrical installation and the same structure; the first elastic component, the first end of the first elastic component is hinged to the first mount component; the second elastic component, the first end of the second elastic component is connected to the second mount component Hinged, the second end of the second elastic component is hinged with the second end of the first elastic component through a hinge; the length and elastic force value of the first elastic component and the second elastic component are the same. The invention can avoid abnormal wear caused by the free swing of the brake caliper unit, and can automatically prompt to replace the brake pads after the brake pads are worn to a limit.

Description

technical field [0001] The invention belongs to the technical field of rail traffic, relates to the braking technology of rail traffic, and in particular relates to an automatic centering device for a brake caliper unit, a brake caliper unit, a limit alarm method and an installation method. Background technique [0002] The brake caliper unit is the actuator of the rail vehicle braking system, which is used to convert the compressed air pressure into mechanical reasoning and amplify, and realize the conversion of the kinetic energy of the rail vehicle through the friction between the brake disc and the brake pad. To achieve the purpose of speed regulation or parking. In the process of converting the kinetic energy of the rail vehicle into thermal energy, the wear between the brake disc and the brake pads mainly consumes the brake pads, and the brake pads are replaced frequently. The replacement cycle of the brake pads is about 6 months, and the replacement cycle of the brak...
