The coupler is provided with a hanging device, and the device keeps the position of the coupler on a horizontal plane and keeps the direction of the coupler in alignment, so that the train is ensured not to be manually intervened in the coupling process.

In order to ensure the state of the coupler in the using process, a regulating function unit is configured for the coupler hanging device. Currently, existing coupler hangers include a horizontal centering device and a vertical height adjustment device.

The horizontal centering device is used for adjusting the transverse centering performance of the coupler hanging device, and the performance of the coupler buffering device is prevented from being influenced by the transverse swing of the coupler buffering device under the conditions of turning and the like. In the prior art, the horizontal centering device generally comprises a double-side centering device which is symmetrically arranged at two sides of the coupler buffering device, and when the coupler buffering device inclines to one side, the horizontal centering device at the inclined side plays a role in promoting the coupler buffering device to restore to the center.

For example, patent publication No. CN105026239A discloses a rail vehicle connector including a connector positioning device symmetrically disposed on both left and right sides, wherein the connector positioning device includes a cylinder configured to pass a compressed fluid. The coupler centering device has the following defects: the installation is needed from two sides, the structure is complex, the occupied space is large, and the installation and debugging are inconvenient.

In order to solve the problem of mounting the buffer restoring mechanism, a lifting lug 201 is arranged on the shell of the buffer 2, a lifting lug 302 is arranged on the supporting seat 3, and the first force transmission element and the second force transmission element are connected to the corresponding lifting lugs. The ends of the first force-transmitting element and the connecting rod 402 are mounted to the respective lifting eyes. The mounting structure of lug coupling formula guarantees that buffering recovery mechanism has the degree of freedom of two directions at least, does not restrict coupling horizontal and vertical swing.

As a specific embodiment, the first force-transmitting element is constructed as follows. Reference may be made to fig. 4 to 8 in combination.

A force transmission rod 7;

first bushing 8: the force transmission rod 7 is sleeved with the force transmission rod, the force transmission rod is positioned in the shell 4, and a first protruding structure 801 is arranged along the outer wall of the first shaft sleeve 8; a gasket 12 is arranged between the first shaft sleeve 8 and the shell 4 and used for buffering the collision between the first shaft sleeve 8 and the shell 4 in the movement process;

the spring 6 is located between the first protruding structure 801 and the second force transferring element.

The first sleeve 8 may be formed as an integral part of the force transmission rod 7 or may be movably mounted on the force transmission rod 7 in a nested manner. If the movable mounting mode is adopted, the positioning problem of the first shaft sleeve 8 needs to be considered. Further, in order to solve this problem, the force transmission rod 7 is provided with a first restriction member which is located at an open end of the housing, outside the first sleeve 8, and which can be inserted or transferred into the open end. The first restriction member may be formed as an integral structure with the force transmission rod 7, and may restrict the outward movement of the first boss 8.

In this embodiment, the force transmission rod 7 is a threaded rod and the first limiting member is a bolt 9 mounted on the threaded rod. The rotary bolt 9 can be rotated to relatively adjust the position of the bolt 9 on the threaded rod, so that the relative position of the first shaft sleeve 8 on the force transmission rod 7 can be adjusted in an auxiliary manner, and the compression capacity can be adjusted. Specifically, the precompression force of the spring 6 is increased when the position of the bolt 9 is adjusted toward the inside of the housing 4, and the precompression force of the spring 6 is decreased when the position of the bolt 9 is adjusted toward the outside of the housing 4.

Further, the inner diameter of the open end 401 of the housing is smaller than the outer diameter of the first protruding structure on the first boss 8. Specifically, the open end 401 of the housing forms a structure protruding toward the inner diameter, which enables the open end 401 of the housing to restrict the movement of the first sleeve 8, and ensures that the spring 6 is smoothly compressed.

The force transmission rod 7 is further provided with a second limiting structure, the second limiting structure is located on the inner side of the cavity 5, and the open end 501 of the cavity forms a protruding structure 701 facing the inner diameter direction of the cavity, so that the second limiting structure and the open end 501 of the cavity form a stop structure.

In addition, in order to form a stable compression structure for the spring 6, a second protruding structure 502 is provided along the outer wall of the cavity 5, and the spring 6 is located between the second protruding structure 502 and the first protruding structure 801 element. Meanwhile, as can be seen from fig. 1, the spring 6 is further sleeved on the first shaft sleeve 8 and the outer wall of the cavity 5, which has a fixing function and prevents the spring 6 from moving.

In order to further fix the spring 6, the buffer recovery unit further comprises a second bushing 10, arranged with the cavity second protruding structure 502 towards the side of the first bushing 8; the notch of the second shaft sleeve 10 is a wedge-shaped notch, the end part of the spring 6 is clamped in the wedge-shaped notch, and the spring 6 is fixed in the notch.

The working principle of the horizontal adjustment of the car coupler hanging device is as follows.

The first force transfer element is coupled to the support base 3 and the second force transfer element is coupled to the draft gear.

The force transmission rod 7 is in shaft connection with a lifting lug 302 of the supporting seat 3; the end of the shell 4 is provided with a section of connecting rod 402 which is coupled with the lifting lug 201 of the shell of the buffer 2.

Referring to the directions shown in the drawings of the specification, the horizontal coupler resetting mechanism is installed on the left side of the coupler buffer device and not installed on the right side of the coupler buffer device when viewed from the supporting base 3 in the direction of the coupler buffer device, taking the axial direction (length direction) of the coupler buffer device as a standard.

When the coupler buffer system deflects towards the left side under the action of external force, relative rotation is generated between the force transmission rod 7 and the lifting lug 302 and between the shell 4 and the lifting lug 201, and the coupler buffer device deviates from the centering position towards the left. External force (compression force) is transmitted to the housing 4 through the lifting lug 201, the housing 4 further transmits the external force to the cavity 5, and at this time, the cavity 5 pushes the spring 6 to move towards the first shaft sleeve 8. When the first bushing 8 is moved into contact with the first limiter bolt 9 on the force transmission rod 7, the first bushing 8 is stopped, but the chamber 5 will be moved further in the direction of the first bushing 8 by the external force, compressing the spring 6. The spring 6 is compressed and generates a counter-spring force which is transmitted via the cavity 5 to the actuating housing 4 and further to the draft gear damping device, so that the draft gear damping device returns to the centered position.

When the coupler buffer system deflects towards the right side under the action of external force, relative rotation is generated between the force transmission rod 7 and the lifting lug 302 and between the shell 4 and the lifting lug 201, and the coupler buffer device deviates from the centering position towards the right. External force (tensile force) is transmitted to the shell 4 through the lifting lug 201, the shell 4 is pulled to rotate, the shell 4 transmits the external force to the first shaft sleeve 8, the first shaft sleeve 8 is always kept in a state of being contacted with the bottom of the shell 4, and the spring 6 is compressed towards the cavity 5. When contact is made between the end on the force transfer rod 7 and the port of the cavity 5, the movement of the cavity 5 is restricted. The first sleeve 8 continues to move towards the chamber 5 compressing the spring 6. The spring 6 is compressed and generates a counter-spring force which is transmitted via the first bushing 8 to the housing 4 and further to the coupler draft gear, so that the coupler draft gear is returned to the centered position.

The buffer restoring element can generate restoring action when the first force transmission element and the second force transmission element are stressed, so the buffer restoring element provided by the invention is arranged on one side of the coupler buffer device along the horizontal swinging direction of the coupler buffer device relative to the car body. Compared with the structure in the prior art, the structure can save the installation quantity of the buffer recovery elements and ensure the centering recovery effect.

The horizontal centering adjusting mechanism can be arranged on the right side of the supporting seat 3 and the coupler buffer device, and the principle is the same, so that the repeated description is omitted.

The direction of installation of the horizontal centering adjustment mechanism can be reversed, i.e. the force transmission rod 7 is mounted to the coupler draft gear and the housing 4 is mounted to the support 3. The working principle is the same as above, and is not described in detail.

The utility model discloses in, the concrete structure of perpendicular recovery mechanism as follows, refer to fig. 1, fig. 2 to and fig. 10, fig. 11, include:

a first elastic unit including an elastic member 14 and an elastic member mounting structure;

the support element comprises a first elastic element mounting end, the coupler buffering device comprises a second elastic element mounting end, the first elastic element mounting end and the second elastic element mounting end are transversely arranged at intervals, and the elastic piece 14 is mounted between the first elastic element mounting end and the second elastic element mounting end through an elastic piece mounting structure.

Specifically, the first elastic member mounting end is the end near the vehicle body side, the second elastic member mounting end is the end near the coupler draft gear, and the first elastic member mounting end and the second elastic member mounting end are laterally spaced to provide a lateral mounting space for the elastic member 14. The lateral direction referred to herein means a direction in which the coupler draft gear extends, and may also be understood as a longitudinal direction of the coupler draft gear.

The transverse mounting structure may be parallel to the ground or non-parallel to the ground. As a preferred embodiment, the spring 14 is mounted parallel to the axis of the draft gear. That is, the elastic deformation direction of the elastic member 14 is made parallel to the ground. The mounting structure can save the mounting space to the maximum extent and can also realize the optimal elastic stopping and rebounding effects.

The resilient member 14 is transversely mounted to compress the resilient member 14 when the draft gear is vertically lowered downwardly, and the resilient member 14 provides a resilient force to inhibit downward lowering of the draft gear. The transverse installation structure effectively utilizes the clearance between the coupler buffer unit and the supporting seat 3, and can save the installation space.

Hereinafter, two mounting structures of the elastic unit at a side close to the supporting member are provided.

A first mounting means, see figures 1 and 2.

The first elastic element mounting end is located on the support base shaft 301, and the elastic element 14 is directly connected with the shaft 301 and can rotate along with the shaft 5. In the prior art, the coupler yoke key 6 is also arranged on the shaft 301 in the support seat 3, the support seat shaft 3 in the prior art is lengthened, the shaft 301 penetrates through the shaft hole more, and the elastic element 14 is arranged on the extension part of the shaft 301. The advantage of this configuration is that the spring 14 is synchronized with the rotation of the coupler draft gear and the shaft, and the spring 14 does not restrict the rotation of the coupler draft gear.

A second mounting, see fig. 11.

The first elastic element mounting end is located on the support base 3, and the elastic member 14 is connected to the support base 3. The supporting seat 3 is provided with the inserting portion 20 through which the protruding shaft 17 can penetrate, and the structure can limit the rotation of the coupler buffering device relative to the mounting seat due to the fact that the supporting seat 3 is fixedly mounted on the car body and the elastic piece 14 cannot rotate after being mounted, and can still play a role in relieving and supporting vertical movement. This type of mounting is relatively less effective than the first type of mounting.

Hereinafter, the structure of the elastic unit will be described in detail.

As mentioned above, the elastic unit includes the elastic member 14, which has the effects of alleviating the vertical movement and keeping the coupler buffer device in the vertical and horizontal posture; and an elastic member mounting structure for mounting the elastic member 14 to the support base 3 and the coupler draft gear.

The elastic member mounting structure comprises a second partition plate 15, an elastic member 14 is connected with the second partition plate 15, the second partition plate 15 is mounted at the mounting end of a second elastic element, the second partition plate 15 serves as a supporting structure of the elastic member 14, a bolt hole 1501 is formed in the second partition plate 15, and the second partition plate is mounted on the coupler buffer device through a fixing member in the form of a bolt and the like. The elastic member 14 may be made of rubber, and the rubber is directly vulcanized with the second partition 15 into a whole, so that the structure is stable.

The elastic member 14 may be a spring or the like, and may be directly attached to the second partition 15.

As a further optimization, the elastic member 14 mounting structure further includes a first partition 16, the elastic member 14 is mounted between the first partition 16 and the second partition 15, and the first partition 16 is mounted to the first elastic member mounting end. Specifically, the first partition 16 is provided with a protruding shaft 17, and the protruding shaft 17 can be mounted to a corresponding shaft hole of the holder shaft 301; or a mounting structure for mounting the elastic member to the support base 3.

The first partition plate 16 also serves as a support structure for the elastic member, similarly to the second partition plate 15, and the end of the first partition plate 16 is attached to the support base 3 or the shaft by a fixing member such as a bolt. The rubber may be directly vulcanized integrally with the second partition 15 and the first partition 16.

As a further optimization, since the elastic member 14 is close to the mounting side of the coupler draft gear, which is the force-receiving side, in order to ensure the stability of the structure of the elastic unit, the cross-sectional area of the elastic member 14 is gradually reduced along the direction from the mounting end of the second elastic element to the mounting end of the first elastic element. If the rubber block is adopted, the rubber block can be designed into a trapezoidal or frustum-shaped structure, and the side with the larger end area faces the mounting end of the second elastic element.

As a further preference, the spring 14 mounting structure includes a support member whose function is to effect a mating mounting of the spring unit to the coupler draft gear side. The second resilient element mounting end is located on a support member mounted to the draft gear, and in particular to draft gear 2.

In this embodiment, support piece specifically includes backup pad 18 and sets up in the supporting pad 19 of backup pad 18 both sides, and backup pad 18 is used for playing main supporting role to buffer 2, and supporting pad 19 plays the auxiliary stay effect for consolidate the support effect.

Due to the fact that different sizes of coupler draft gears exist, different requirements are required for the positions of supporting points of the supporting parts, and the following design is further made. The support plate 18 is non-fixedly attached to the draft gear assembly, and more particularly, the support member is configured to engage the draft gear assembly, such as by forming the draft gear housing as a cylinder, and the support member is configured to engage the draft gear housing as a channel, and the support member supports the draft gear housing. The support plate 18 is connected to the second partition 15 by means of an adjustable bolt 13, the adjusting end of which is located on the support side.

The hanging device for the coupler can be applied to various coupler buffer devices. By adopting the car coupler hanging device, the vertical level holding performance of the car coupler buffer device can be improved, the occupied space can be reduced, meanwhile, the universality is good, and various types of car coupler systems can be conveniently transplanted.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
