Abstract
The utility model discloses a shaft-mounted braking disc for railway locomotives, which comprises a disc hub, a disc body and a spacer ring, the disc body and the disk hub are fixedly connected via fasteners, the disc body is formed by a plurality of disc blocks, two sides of the disc hub are respectively equipped with at least two disc blocks, and the back of the disc block is provided with radiating ribs. The shaft-mounted braking disc increases radiating areas, and is fine in thermal cracking resistance, thereby facilitating exchange.
Description
Technical field
The utility model relates to a kind of axle-mounted brake disk of rail vehicles.
Background technique
Along with improving constantly of domestic train running speed, have higher requirement to train braking system, and brake disc to be as the power unit of train braking, its performance quality directly determines the performance of braking system.The following train of present domestic 160km/h adopts cast iron brake disk, and on the train more than the speed 200km/h, the thermal capacity of cast iron brake disk can not meet the demands, and must use Forging Steel Brake Disc.Present domestic Forging Steel Brake Disc is used less, and the Forging Steel Brake Disc of domestic-developed mainly is the china academy of railway sciences exploitation, is applied to " China Star " and waits on some tentative rail motor set.
The axle-mounted brake disk that uses mainly is made up of parts such as dish hub, disk body, spacer rings at present, and its mid-game hub is connected by fastening piece with disk body.Disk body is 1 or two, and it makes brake disc wearing away limit back replacing inconvenience, needs external force disk body to be smashed or releases wheel; Disk body only is distributed in the one-sided of dish hub, makes brake disc in use produce bigger radial deformation, and makes the stressing conditions of bolt bad; Disk body makes that for not with the structure of radiating fin or inner distribution radiating fin the heat dispersion of brake disc is not high, more is easy to generate defectives such as hot crack; Fastening piece is that the diameter of thread is the following bolt of M14, makes that the rigidity of bolt is not strong; Spacer ring is one, and is not with flange, make spacer ring processing need higher precision, and spacer ring can not play the effect that prevents that fastening piece is loosening; Brake disc is not with radiating fin or inner distribution radiating fin, makes the brake disc heat dispersion reduce, and makes that the processing of brake disc radiating fin is difficult, and machining accuracy and quality of processing are difficult for guaranteeing, also influence the dynamic balance performance of brake disc.
Summary of the invention
The purpose of this utility model is to provide a kind of heat diffusion area, heat crack resistance that can increase brake disc good, the axle-mounted brake disk of being convenient to change.
In order to achieve the above object, the technical solution of the utility model is: a kind of axle-mounted brake disk comprises dish hub, disk body and spacer ring, disk body is fixedlyed connected by fastening piece with the dish hub, disk body is made of some disk body pieces, and each arranges at least 2 disk body pieces dish hub both sides, and the disk body piece back side has radiating fin.
The disk body piece is 4, respectively arranges 2 in dish hub both sides.
Described fastening piece is high-strength bolt and nut.
Spacer ring is two, is distributed in a side of dish hub, and every is half-turn.
Spacer ring has flange.
The sectional shape of radiating fin is trapezoid shaped on the disk body piece, and the friction plate adjacent of radiating fin bottom and disk body piece has fillet.
Coil between the adjacent disk body piece of each side of hub and locate mutually by locating stud.
After adopting said structure,, make that the replacing of axle-mounted brake disk after wearing away limit is very convenient, only need loosening fasteners, change new axle-mounted brake disk disk body and get final product because disk body is a polylith; Disk body is distributed in the both sides of dish hub, makes that the stressing conditions of fastening piece is good, and makes that disk body radial deformation under the situation of being heated is very little, makes axle-mounted brake disk not need to add special construction and eliminates radial deformation stress, and make the connection fastening piece not be subjected to shear deformation; Radiating fin is arranged at the back side of every disk body piece, makes the heat diffusion area of axle-mounted brake disk increase greatly, and axle-mounted brake disk intensity is increased greatly, improves the thermal capacity of axle-mounted brake disk greatly, improves the heat crack resistance of disk body; Fastening piece is preferably the high-strength bolt of the diameter of thread more than M24, has not only guaranteed the reliability that brake disc connects, and brake disc can better be located by bolt, has improved the dynamic balance performance of axle-mounted brake disk; Spacer ring is preferably two, at the spacer ring inner circle flange is arranged, and makes spacer ring can not produce tensile stress because of the axle-mounted brake disk thermal distortion in braking process, destroy spacer ring, flange can also prevent that fastening piece from rotating, and not only makes axle-mounted brake disk easy for installation, can also play locking effect; The back side distribution sectional shape of disk body piece is trapezoidal radiating fin, make radiating fin be suitable for forging processing, and have good intensity and heat dispersion, but also make because radiating fin is processed caused brake disc unbalancing value seldom, the dynamic balance performance of axle-mounted brake disk improved greatly; Locate mutually by locating stud between the disk body piece of each side of dish hub, not only make the assembly precision of axle-mounted brake disk higher, also make to connect each other between two of the axle-mounted brake disks, eliminated the height difference problem between one-sided adjacent two disk body piece seams after the axle-mounted brake disk temperature distortion.
