Embodiment Construction

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, 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] like figure 1 , figure 2 , image 3 As shown, the split 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 positioning...

Abstract

The invention relates to a split type wheel-mounted brake disc. The split type wheel-mounted brake disc comprises a plurality of disc bodies arranged in the circumferential direction, butt-joint connecting columns are arranged at the butt-joint ends of the disc bodies, pin grooves with opposite openings and positioning grooves with opposite openings are formed in the connecting columns correspondingly, the axes of the pin grooves are parallel to the diameter of the splicing position of the disc bodies, the mouth diameters of the openings of the pin grooves are smaller than the maximum inner diameter of the interior of the pin grooves, the axes of the positioning grooves are perpendicular to the brake disc face and located on the side, away from the brake disc face, of the pin grooves, pinsare inserted into the pin grooves of the connecting columns in the radial direction to achieve connection between the disc bodies and limit circumferential and axial movement between the disc bodies,limiting grooves perpendicular to the brake disc face is formed in the pins, positioning blocks are provided with limiting columns corresponding to the limiting groove, the limiting columns are embedded into the limiting grooves while the positioning blocks are inserted into the positioning grooves in the axial direction, radial movement between the disc bodies is limited, the shape pins are prevented from sliding out in the radial direction, and therefore displacement full-constraint reliable connection between the disc bodies is achieved.

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...
