In some conventional brake devices, the brake device is connected to the axle, and the brake is applied by an annular brake disc in the brake device, and when the brake device is connected to the axle, the brake device is usually connected by two end sleeves, and the two end sleeves are usually connected to the brake device by flanges, so that the axle is connected with the wheel set to form a brake device system. In general, maintenance of a brake disc in a brake device requires disassembly and disassembly of the wheel set, axle, and brake device as a whole, and then the annular brake disc can be removed or inserted. In this regard, the technical scheme of the utility model can realize the disassembly and assembly of the annular brake disc under the condition of incomplete disassembly and assembly.

A brake device according to the present utility model is described below with reference to fig. 1 to 3, and is configured to be connected to an axle of a railway vehicle, and includes a brake portion 300, wherein the brake portion 300 has a cylindrical cage housing and a brake disc 303 mounted inside the housing, two ends of the brake portion 300 are respectively connected with a sleeve 200, two ends of the sleeve 200 are respectively configured with a plurality of flanges 201 in a radial direction, the flanges 201 at the two ends are arranged in a one-to-one correspondence with each other on a coaxial line N, and a dismounting tool 100 of any one of the embodiments is connected between each of the corresponding flanges 201.

As shown in fig. 4, one end of the sleeve 200 is a pipe body structure 202, the other end of the sleeve 200 has an annular flange edge 203, the same two ends of the housing of the brake device are respectively provided with annular connecting flanges, the sleeve 200 is fixedly connected to two ends of the brake portion 300 through the connecting flanges, the sleeve 200 is provided with a flange 201, the flange 201 freely extends outwards along the radial direction of the sleeve 200, and the dismounting tool 100 is connected between the corresponding flanges 201, that is, the dismounting tool 100 can be connected with the brake device as a whole. The radial extension of the flange 201 makes the connected dismounting tool 100 be placed on the periphery of the braking portion 300, and no influence is caused on the normal operation of the braking portion 300.

The flanges 201 are arranged such that at least one gap between adjacent flanges 201 allows the brake 300 to pass through, and a considerable distance is provided between the dismounting tool 100 connected to the flange 201 and the brake 300 due to the radial extension of the flanges 201, so that a dismounting space a is formed between the dismounting tools 100 connected to the flange 201. Theoretically, the farther the distance between the dismounting tool 100 and the brake portion 300 is, the more the position where the brake portion 300 is allowed to pass can be provided, but the more the flange 201 is extended relatively, the more the occupied space is, which causes unnecessary space waste.

In some embodiments, the flanges 201 are symmetrically arranged along the center line L, so that the support rods 101 at the closest distance can provide the required disassembly space a, so that the assembly space of the disassembly tool 100 can be saved, for example, in an ideal case, two flanges 201 are arranged at two opposite sides of the center line L, and the two flanges 201 only need to extend radially beyond the space where the disassembly tool 100 can be assembled, that is, the flanges 201 extend radially a little greater than the diameter of the support rods 101 in the disassembly tool 100, and because the two disassembly tools 100 are located at two sides of the center line L, the distance between the two disassembly tools 100 is greater than the diameter distance of the brake part 300, that is, the brake part 300 can be taken out or put in from the disassembly space a between the disassembly tools 100.

It will be appreciated that in a specific example, the brake portion 300 includes a housing and an annular brake disc 303 mounted inside the housing, the housing is integrally configured in a cylindrical structure, and annular connecting flanges are respectively configured on both ends of the housing in the cylindrical structure, and are connected with the sleeve 200 through the connecting flanges. The cylindrical shell makes it more convenient when taking out.

In a specific embodiment, there are at least two flanges 201 on each side opposite the centerline L. As can be seen from the above description, the present application needs to maintain the stability of the structures such as the two-end shaft sleeves 200 by the dismounting tool 100 when the brake device is dismounted or mounted, and this requires the connected supporting tool to have sufficient stability and reliability for supporting.

In this embodiment, in the structure with at least two flanges 201 on each side, at least four sets of dismounting tools 100 are connected to each brake device, and the four sets of dismounting tools 100 are located on two sides of the center line L, thereby forming a rectangular support body connected between the shaft sleeves 200 at two ends, theoretically, if the stability and strength of the support need to be adjusted, the number of the flanges 201 can be increased or decreased at corresponding positions on two sides, respectively, the number of the flanges 201 is increased, which means that the number of the support rods 101 is increased, at this time, the structural stability and strength are effectively improved, correspondingly, the number of the flanges 201 is decreased, then the number of the support rods 101 is reduced, the operation is convenient, the occupied space is small, and the manufacturing is convenient.

As further shown in fig. 4, in the specific example, the sleeve 200 has a funnel-shaped structure, an annular flange edge 203 is provided at an opening end thereof, the flange 201 extends outwardly from the annular flange edge 203, and a through hole is formed at an end of the flange 201 extending. When the supporting seat 102 is connected, the locking bolt 103 passes through the through hole to be connected with the locking screw hole 102-1 on the supporting seat 102, so that the supporting seat 102 is fixed on the flange 201, the bolt connection mode is more flexible, and the application range is wider. In a more specific embodiment, a plurality of vent holes are machined into the sleeve 200.

In some embodiments, the brake 300 includes a cage housing and a brake disc 303 mounted inside the housing, the housing being composed of a first housing 301 and a second housing 302 that are detachably connected.

The first shell 301 and the second shell 302 are formed by split structures, when the brake disc 303 needs to be replaced, the first shell 301 or the second shell 302 can be detached through the detachable connection structure, and the machine is replaced, so that the convenience of detachment is further improved.

Specifically, the first casing 301 and the second casing 302 are respectively configured with the connection portions 304, the connection portions 304 respectively extend along the axial direction of the casings, and are connected by means of bolts when the first casing 301 and the second casing 302 are connected, so that the first casing 301 and the second casing 302 form a casing body in a manner of being buckled up and down, and the disassembly of the upper casing and the lower casing can be realized more conveniently by screwing the bolts of the connection portions 304 when the disassembly is performed.

It will be appreciated that when the housing main body is connected in a split type, the space in which the flange 201 protrudes can be effectively saved, and as described above, it is necessary to make the flange 201 have a certain extension length in order to have a gap through which the brake device passes, but for the above-described embodiment, by arranging the housing in a split type structure, it is apparent that the dismounting space a that can satisfy the passage of the housing can be reduced, and thus the extension distance of the flange 201 can be effectively shortened, thereby achieving the purpose of saving space.

Wherein the distance S between the axis N between the flanges 201 and the central axis i between the bushings is equal, i.e. the distances that the flanges 201 on the bushing 200 extend in radial direction are the same, such that the flanges 201 form an outer circle with the central axis i. The arrangement with the central axis i is that the assembly and disassembly tools can have better overall support stability and reliability after being connected.

Further, the brake disc 303 includes a split stationary disc of a semi-annular structure and a split movable disc of a semi-annular structure.

The split type static disc and the split type movable disc are of a semi-annular split type structure and are assembled in the first shell 301 and the second shell 302 respectively, so that the operation of removing and replacing the brake disc 303 is more convenient, namely, the semi-annular brake disc 303 can be directly taken down for replacement by removing the first shell 301 or the second shell 302.

As shown in fig. 5, according to another aspect of the present utility model, there is provided a dismounting tool for a brake device according to the above embodiment, wherein the dismounting tool 100 is configured to be suitable for dismounting the brake device, and comprises a support rod 101, two ends of the support rod 101 are respectively connected with a support seat 102 in a threaded manner, the support seats 102 at the two ends have threads with opposite directions, the support seats 102 are configured to be capable of being separated from or approaching each other, and locking screw holes 102-1 suitable for fixing the support seats 102 on the brake device are configured on the support seats 102.

As shown in fig. 2, the supporting seats 102 at two ends have threads with opposite rotation directions, and the supporting seats 102 at two ends are in threaded connection with the supporting rod 101 in the middle, that is, the supporting seats 102 at two ends are either close to each other or far away from each other when the supporting rod 101 rotates, and a locking screw hole 102-1 is formed in the supporting seat 102, the supporting seat 102 can be fixed on the shaft sleeves 200 at two ends of the braking device through the locking screw hole 102-1, and the supporting seats 102 at two sides are connected to the shaft sleeves 200 at two ends of the braking device through threads, so that the dismounting tool 100 can be flexibly dismounted.

When the brake device is disassembled, the shaft sleeve 200 is firstly disassembled from the connecting flange bolts of the brake device, the supporting seats 102 at the two ends can be driven to be far away by the rotation of the supporting rods 101, at the moment, the supporting rods 101 generate thrust with opposite acting force to the shaft sleeves 200 at the two ends, so that the shaft sleeves 200 are separated from the brake device, the shaft sleeves 200 at the two ends are supported and kept stable under the action of the supporting rods 101, and the brake device can be independently taken out to replace the annular brake disc. Since the shaft sleeves 200 at both ends need to be stably supported, a plurality of dismounting tools 100 can be used at a time to support, and at least one dismounting space a enough to take out the brake device is ensured when the plurality of dismounting tools 100 are used for position selection.

When the ring brake disc is mounted, that is, after the replacement of the ring brake disc is completed, the brake device is mounted through the mounting/dismounting space a, and then the support rods 101 are rotated in the opposite direction with respect to the mounting/dismounting time, so that the support seats 102 are brought close to each other to complete the connection of the both end bosses 200 of the brake device. This completes the replacement of the annular brake disk without complete disassembly.

It will be appreciated that, as further shown in fig. 1, the threaded connection of the two ends of the supporting rod 101 and the locking screw hole 102-1 on the supporting seat 102 make the dismounting tool 100 more widely applicable. In theory, the sizes of the braking devices are different according to the braking force requirements, while the supporting rods 101 can be matched by changing the sizes, and similarly, the loads required to be carried by the braking devices with different sizes are different, so that the matching can be performed by changing the sizes of the supporting seat 102 and the locking bolts 103, thereby the overall applicability is wider.

In a specific example, the support rod 101 has internal threads at both ends, the two support seats 102 are external threads, the heads of the two support seats 102 are machined with locking screw holes 102-1, the locking screw holes 102-1 extend in the axial direction of the support seat 102 to be blind holes, and the internal threads are machined in the locking screw holes 102-1, so that the support seat 102 is fixed on the shaft sleeve 200 of the brake device by the locking bolts 103.

Further, the rod body of the support rod 101 is provided with an engaging portion 101-1 adapted to screw the support rod 101 in cooperation with the attaching/detaching tool. Specifically, the engaging portion 101-1 may have various structures, and the supporting rod 101 can be effectively rotated by the engagement of the engaging portion 101-1 with the attaching/detaching tool. For example, the engaging portion 101-1 may be a through hole penetrating the support rod 101, a rod body is inserted into the through hole to rotate the support rod 101, a notch for engagement with a socket wrench, or a raised hexagonal mesa structure formed on the rod body, the raised hexagonal mesa structure being capable of engagement rotation with the socket wrench. The position of the engaging portion 101-1 is located at the middle of the support rod 101.

In a specific embodiment, the brake device of each wheel set is configured with four dismounting tools 100, and the four dismounting tools 100 are arranged outside the brake device housing in a rectangular shape.

At this time, the four sets of dismounting tools 100 replace the casing of the braking device to connect the shaft sleeves 200 at two ends into a whole, so that the shaft sleeves 200 are guaranteed to be connected with the wheels at two sides in an integral way, the vertical load of the wheel set is borne, and the shaft sleeves 200 at two sides and the wheels are prevented from being unbalanced.
