Embodiment Construction

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0020] Such as figure 1 , figure 2 , image 3 As shown, the split-type wheel-mounted brake disc in this embodiment includes two semi-circular A disc body 1 and B disc body 5, and the ends of A disc body 1 and B disc body 5 are arranged with connecting columns 2 The connecting column 2 is provided with a pin groove 6 with an opposite opening and a positioning groove 7 with an opposite opening. The axis of the pin groove 6 is parallel to the diameter of the splicing part of the disc body, and the pin groove 6 is C-shaped, that is, the diameter of the opening of the pin groove 6 is smaller than the maximum inner diameter of the pin groove 6 . The axis of the ...

Abstract

The invention relates to a split-type wheel-mounted brake disc, which comprises a plurality of disc bodies arranged along the circumferential direction, and the ends of the disc bodies are arranged with paired connecting columns, and the connecting columns are respectively provided with pin grooves and openings opposite to each other. The opening of the positioning slot is opposite, the axis of the pin slot is parallel to the diameter of the joint of the disc body and the diameter of the opening of the pin slot is smaller than the maximum inner diameter of the pin slot, the axis of the positioning slot is perpendicular to the brake disc surface and the positioning slot is located far away from the brake disc. On one side of the moving disk surface, the pin is inserted radially into the pin groove of the connecting column to realize the connection between the disk bodies and limit the circumferential and axial movement between the two. The pin is provided with a limit perpendicular to the brake disk surface The positioning block has a corresponding limit post. When the positioning block is inserted into the positioning slot in the axial direction, the limit post is embedded in the limit slot to limit the radial movement between the discs and prevent the shape pin from sliding out in the radial direction. , so as to realize the fully constrained reliable connection between the discs.

Description

technical field [0001] The invention relates to a method for connecting disc bodies of wheel-mounted brake discs for rail vehicles, which is suitable for rail trains of various models using wheel-mounted brake discs. [0002] technical background [0003] Disc brakes are generally used for rail transit trains with a speed above 80km / h, including wheel-mounted brake discs and shaft-mounted brake discs. The wheel-mounted brake disc is located on both sides of the wheel, and is tightly fitted to the wheel web through positioning posts and bolt fasteners. [0004] The brake disc is subjected to a variety of loads during the braking process, as well as wear from the brake pads. The failure of the brake disc is usually manifested as the wear-to-limit failure and the failure of the fatigue crack length on the friction surface. In the process of train operation and maintenance, it often occurs that the brake disc needs to be replaced due to the failure of the brake disc. At present...
