Problems solved by technology

For the structure of the existing wheel-mounted brake disc, when replacing the brake disc, the wheel needs to be removed first, and then the replacement can be performed. The operation is inconvenient and the cycle is long, especially during the process of removing the wheel, it will cause damage to the hub hole and the axle box bearing, which will increase maintenance. Manpower and material costs in the maintenance process

Embodiment 1

[0022] A method for connecting brake discs with split wheels, including disc body A 1 and disc body B 4, positioning sleeves and hexagon socket screws 2, disc body A 1 and disc body B 4 have exactly the same structure, and disc body A 1 and the back side of the plate body B 4 adopt strip-shaped heat dissipation ribs, such as figure 1 shown.

[0023] Grooves 5 and flanges 6 are respectively arranged at both ends of the disc body A 1 and the disc body B 4, positioning holes A 7 and threaded holes 8 are provided on the grooves 5, counterbores 10 and positioning holes B 9 are provided on the flanges, like figure 2 , image 3 , Figure 4 , Figure 5 shown.

[0024] The positioning sleeve 3 passes through the flange 6 and the groove 5 accordingly to realize the radial and circumferential positioning of the disc body A1 and the disc body B4, as figure 1 As shown, the inner hexagon screw 2 is tightened through the positioning sleeve 3 and the threaded hole 8 to realize the axia...

Abstract

The invention provides a connection method for a split wheel-installed brake disk. A disk body A (1) and a disk body B (4) used by the connection method have identical structures. Grooves (5) and flanges (6) are respectively arranged at two ends of the disk body A and disk body B. Locating holes A (7) and threaded holes (8) are formed in the grooves. Counter bores (10) and locating holes B (9) areformed in the flanges (6). Locating sleeves (3) penetrate through the flanges (6) and the grooves (5) in sequence, and radial direction and circumferential direction location of disk body A (1) and disk body B (4) is achieved. Withdrawal holes (13) are formed in the locating sleeves. Inner hexagon screws (2) penetrate through the locating sleeves (3) and are screwed tightly with the threaded holes (8), axial direction location of disk body A (1) and disk body B (4) is achieved, and thus full-constrained reliable connection of displacement of disk body A (1) and disk body B (4) 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] For rail transit trains with a speed of 160km / h or more, disc brakes are generally used at present, 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...
