Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] For the spliced ​​anti-warping brake disc, the first disc body 1 and the second disc body 8 see the attached figure 1 .

[0016] The first disc body 1 and the second disc body 8 of the spliced ​​anti-warping brake disc, each disc body is connected as a whole by columnar heat dissipation ribs 2, long heat dissipation ribs 4, short heat dissipation ribs 5 and friction ring 6. Both the first disc body 1 and the second disc body 8 are made of low-alloy steel, and are formed by casting or forging.

[0017] The outer edges of the first disc body 1 and the second disc body 8 of the spliced ​​anti-warping brake disc are provided with the same number of columnar heat dissipation ribs 2, and the first through groove 3 and the second through hole of the columnar heat dissipation ribs 2 are processed by turning. Slot 7. The first through groove 3...

Abstract

Disclosed is a splicing type contra warping prevention axial loading brake disc. The outer edge of a disc body (1) and the outer edge of a disc body (8) are each provided with columnar radiating ribs (2) which are all provided with through grooves (3 and 7) by a turning method. The through grooves (3) are located in the outer sides of the columnar radiating ribs (2) of the disc body (1), and openings of the through grooves face the external diameter direction of the brake disc; the through grooves (7) are located on the columnar radiating ribs (2) of the disc body (8); and cutting openings of the through grooves (7) face the axis side of the brake disc. The disc body (1) and the disc body (8) are rotatably assembled to enable the through grooves (3 and 7) in the columnar radiating ribs (2) to achieve covering and splicing. When contra warping deformation occurs to the disc body (1) and the disc body (8), the matching faces of the through grooves (3 and 7) make contact to prevent axial warping deformation from continuously happening to the disc body (1) and the disc body (8), and different degrees of contra warping deformation is controlled by adjusting the opening angle and the matching gap of the through grooves (3 and 7).

Description

technical field [0001] The invention relates to the technical field of rail vehicle disc brakes, in particular to a spliced ​​anti-warping shaft-mounted brake disc. technical background [0002] China is vigorously developing express trucks above 160km / h and EMUs and high-speed trains above 200km / h. Practice has proved that when the train running speed increases to more than 120km / h, the traditional brake shoe-wheel tread braking can no longer meet the requirements of train braking, so the basic braking methods of express freight cars and high-speed EMU trains adopt disc brakes. move. [0003] The brake disc is a key component that converts the kinetic energy of the train into heat energy through friction energy. At present, most of the shaft-mounted brake discs used in freight trains and high-speed railways at home and abroad are integral brake discs, and a small part adopt spliced ​​split discs. Body brake discs. Integral discs are constrained by themselves, and the str...
