Description

Technical Field

[0001] The invention relates to the technical field of rail vehicle braking devices, and in particular to a wing-shaped elastic mounting structure of a braking device. Background Art

[0002] At present, when rail transit vehicles use wheel discs or axle discs for braking, the brake calipers that execute the braking instructions are rigidly mounted on the bogie frame through fastening bolts. In general, one set of existing mounting structures can only install one set of brake calipers, and the structure is dispersed, the brake pipeline layout is difficult, and it is not conducive to maintenance. The existing mounting structure is usually connected to the bogie by welding or fasteners. The welded mounting structure cannot adjust the position, which is not conducive to ensuring the relative position relationship between the caliper and the brake disc when the brake caliper is installed; due to the large braking force, the mounting structure connected by fasteners has high requirements on the strength of the fasteners and the operation requirements for workers when installing the fasteners, and there are still problems of dispersed installation and subsequent maintenance difficulties. In addition, both the welding method and the direct connection method with fasteners are rigid connections, which are very unfavorable to the strength of the mounting structure due to the large braking force and vibration during operation.

[0003] Therefore, based on the above technical problems, technicians in this field urgently need to develop a wing-shaped elastic mounting structure for a braking device. Summary of the invention

[0004] The object of the present invention is to provide a wing-shaped elastic mounting structure of a braking device, which has high integration, reliable mounting method, excellent vibration resistance, and is easy to transport, install and maintain.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A wing-shaped elastic mounting structure of a braking device according to the present invention comprises:

[0007] a wing-shaped body; and

[0008] A first connector formed in the middle of the wing-shaped body and extending toward one side, and a second connector symmetrically arranged on one side of the wing-shaped body relative to the first connector;

[0009] The parts of the wing-shaped body located on both sides of the first connecting body are brake device mounting parts for mounting the brake device;

[0010] The first connecting body and the second connecting body are both provided with connecting holes, and elastic elements are installed in the connecting holes. The mounting structure is connected to the frame through the elastic elements of the corresponding connecting bodies.

[0011] Furthermore, the connection position between the first connector and the wing-shaped body has a reinforcing rib;

[0012] The position where the wing-shaped body cooperates with the braking device is provided with reinforcing ribs.

[0013] Furthermore, the brake device mounting portion is provided with two groups of mounting holes, namely a first mounting hole and a second mounting hole;

[0014] The first mounting hole is provided on the reinforcing rib at the matching position between the wing-shaped body and the braking device;

[0015] The second mounting hole is formed on a mounting body protruding from the surface of the mounting portion of the brake device;

[0016] The first mounting hole is used to mount the braking device, and the second mounting hole is used to mount the connecting rod of the braking device.

[0017] Furthermore, the wing-shaped body is also protruded to form an extreme working condition anti-slip portion;

[0018] A safety pin is installed on the extreme working condition anti-detachment part.

[0019] Furthermore, the first connector and the position where the first connector and the wing-shaped body cooperate are both provided with hollow process holes.

[0020] In the above technical solution, the wing-shaped elastic mounting structure of a braking device provided by the present invention has the following beneficial effects:

[0021] The mounting structure of the present invention symmetrically forms a brake device mounting structure on both sides of the wing-shaped body, and the brake device required for a single axis is integrated and installed on the same mounting structure, which can greatly reduce the complexity of the brake pipeline layout. The two sets of brake devices are symmetrically arranged, which improves the stress characteristics of the mounting structure.

[0022] The connection between the mounting structure and the frame of the present invention is installed by elastic elements. The use of elastic elements can not only attenuate the reaction force generated by braking and transmitted to the frame, but also block the vibration generated by the braking device and the mounting structure itself from being transmitted to the frame, thereby improving the safety of the bogie.

[0023] The mounting structure of the present invention is also designed with an extreme working condition anti-slip structure, which improves the reliability of the mounting structure and the safety of the braking system. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] See also Figures 1 to 4 As shown;

[0035] A wing-shaped elastic mounting structure of a brake device according to this embodiment, the wing-shaped elastic mounting structure comprises:

[0036] A wing-shaped body 1; and

[0037] A first connector 201 is formed in the middle of the wing-shaped body 1 and extends toward one side, and a second connector 202 is symmetrically arranged on one side of the wing-shaped body 1 relative to the first connector 201;

[0038] The parts of the wing-shaped body 1 located on both sides of the first connecting body 201 are the brake device mounting parts 101 for mounting the brake device 7;

[0039] The first connecting body 201 and the second connecting body 202 are both provided with connecting holes 203, and elastic elements 8 are installed in the connecting holes 203. The mounting structure is connected to the frame through the elastic elements 8 of the corresponding connecting bodies.

[0040] Specifically, the present embodiment discloses a wing-shaped elastic mounting structure. The existing brake device mounting structure is usually a "one-to-one" type, which is installed on the frame by a rigid connection method such as fastener connection or welding. The structure of the method of installing a set of brake devices in one mounting structure is too scattered, resulting in a complex layout of the brake pipeline, which is not conducive to maintenance. The wing-shaped elastic mounting structure of the present embodiment is an integrated structure, which is divided into a wing-shaped body 1 and a first connector 201. At the same time, in order to cooperate with the assembly of the component, a second connector 202 is also formed at the lower end of the wing-shaped body 1. The mounting structure of the present embodiment is connected to the component through the first connector 201 and the two second connectors 202 through an elastic element 8. The elastic element 8 can be a conventional elastic element in the prior art. The working principle of the elastic element 8 will not be repeated here. The present embodiment replaces the existing fastener connection or welding method with the connection of the elastic element 8, which is a non-rigid connection method.

[0041] Secondly, brake device mounting parts 101 are formed on both sides of the wing-shaped body 1 of this embodiment, and two brake devices 7 are symmetrically mounted through the brake device mounting parts 101, which solves the problem of brake pipe layout and has a very compact structure.

[0042] Preferably, in this embodiment, the connection position between the first connector 201 and the wing-shaped body 1 has a reinforcing rib 4; the position where the wing-shaped body 1 cooperates with the braking device 7 has a reinforcing rib 4.

[0043] Preferably, the brake device mounting portion 101 of the present embodiment is provided with two groups of mounting holes, namely a first mounting hole 102 and a second mounting hole 103; the first mounting hole 102 is opened on the reinforcing rib 4 at the matching position of the wing-shaped body 1 and the brake device 7; the second mounting hole 103 is opened on the mounting body protruding from the surface of the brake device mounting portion 101; the first mounting hole 102 is used to install the brake device 7, and the second mounting hole 103 is used to install the connecting rod of the brake device 7.

[0044] The device of this embodiment is mainly divided into a connecting body connected to the frame and a brake device mounting portion 101 of the wing-shaped body 1 connected to the brake device 7; and considering the structural strength problem, this embodiment is designed with reinforcing ribs 4 at the position where the wing-shaped body 1 cooperates with the brake device 7, and at the position where the wing-shaped body 1 cooperates with the first connecting body 201, and the overall bearing capacity is improved by the reinforcing ribs 4. At the same time, according to the installation requirements, corresponding connecting holes 203 and mounting holes are opened, and the specific installation method is as described above.

[0045] Preferably, the wing-shaped body 1 of the present embodiment is further provided with an extreme working condition anti-detachment portion 3 protruding therefrom; and a safety pin 5 is mounted on the extreme working condition anti-detachment portion 3 .

[0046] Preferably, the first connector 201 of this embodiment and the position where the first connector 201 and the wing-shaped body 1 cooperate are all provided with hollow process holes 6. In order to further achieve weight reduction and installation and lifting of the structure, this embodiment opens a plurality of process holes 6, and sets an anti-slip hanger at the installation position, that is, the above-mentioned extreme working condition anti-slip part 3, and uses the extreme working condition anti-slip part 3 to install a safety pin 5 with an anti-slip function. The anti-slip hanger of this embodiment does not form a connection with the frame under normal working conditions, and is only used to prevent the installation structure from being separated from the frame under fault conditions, so as to ensure that the braking system can be used normally under fault conditions.

[0047] In the above technical solution, the wing-shaped elastic mounting structure of a braking device provided by the present invention has the following beneficial effects:

[0048] The mounting structure of the present invention symmetrically forms a brake device mounting structure on both sides of the wing-shaped body 1, and the brake device 7 required for a single axis is integrated and installed on the same mounting structure, which can greatly reduce the complexity of the brake line layout. The two sets of brake devices 7 are symmetrically arranged, which improves the stress characteristics of the mounting structure.

[0049] The connection method between the mounting structure and the frame of the present invention adopts elastic element 8 for installation. The use of elastic element 8 can not only attenuate the reaction force generated by braking and transmitted to the frame, but also block the vibration generated by the braking device 7 and the mounting structure itself from being transmitted to the frame, thereby improving the safety of the bogie.

[0050] The mounting structure of the present invention is also designed with an extreme working condition anti-slip structure, which improves the reliability of the mounting structure and the safety of the braking system.

[0051] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
