The auxiliary ring 18 is disposed between the upper end plate 11 and the lower end plate 12, and the auxiliary ring 18 is further disposed outside the diaphragm plate 16, so that the auxiliary ring 18 is not preferably disposed as an annular whole for facilitating auxiliary assembly. In this embodiment, the auxiliary ring 18 may be made of an elastic material, and the auxiliary ring 18 may be a rubber and a metal vulcanized together, wherein the rubber is disposed inside the auxiliary ring 18 and the metal is disposed outside the auxiliary ring 18.

And the gap S2 between the auxiliary ring 18 and the diaphragm plate 16 is also smaller than the gap S1 between the upper and lower end plates 11 and 12 and the vertical diaphragm plate 15.
As shown in fig. 6, 7 and 9, the front coupler 31 includes a front coupler body 311 and a front coupler bottom plate 312, the front coupler bottom plate 312 is seamlessly connected below the front coupler body 311, a front coupler cavity 313 penetrating the front coupler body 311 is formed on the front coupler body 311, a front bottom plate hole 314 penetrating the front coupler bottom plate 312 is formed on the front coupler bottom plate 312, and the size of the front bottom plate hole 314 in the radial direction is smaller than that of the front coupler cavity 313.

The rear coupler 32 includes a rear coupler body 321 and a rear coupler end plate 322, and a rear coupler plate hole 323 penetrating the rear coupler body 321 is formed at one side of the rear coupler body 321, so that the rear coupler end plate 322 is formed above and below the rear coupler plate hole 323, and a shaft mounting hole 324 penetrating the rear coupler end plate 322 is formed at an outer side of the rear coupler end plate 322 above and below.
As shown in fig. 8, the metal joint includes a joint outer ring 21, a joint inner ring 22 and a pin shaft 23, the joint outer ring 21 is sleeved on the joint inner ring 22, an inner ring through hole 221 penetrating through the joint inner ring 22 is formed in the middle of the joint inner ring 22, and the pin shaft 23 is installed in the inner ring through hole 221 in an interference fit manner. The pin 23 includes an ear plate 231 and a shaft body 232, the ear plate 231 is integrally formed at the upper end of the shaft body 232, a through hole is formed at the lower end of the shaft body 232, and the cotter 24 passes through the through hole at the lower end of the shaft body 232. The outer side surface of the joint inner ring 22 is a spherical surface, and the inner side surface of the joint outer ring 21 is a spherical surface matched with the outer side surface of the joint inner ring 22, so that the pin shaft 23 can drive the joint inner ring 22 to rotate relative to the joint outer ring 21 when rotating.
As shown in fig. 1 to 9, the specific installation process of the composite coupler is as follows: the end plate, the intermediate partition plate and the rubber body are vulcanized into a whole, and the rubber joint 1 is assembled after the auxiliary ring 18 is assembled. The joint inner ring 22 and the joint outer ring 21 of the metal joint are arranged in the partition plate through hole 17 of the vertical partition plate 15 in an interference fit mode, and the metal joint and the rubber joint 1 can be combined into a composite joint. The composite knuckle is then installed in the front coupler 31 in an interference fit such that the outer sides of the secondary ring 18, the upper end plate 11 and the lower end plate 12 are all against the inner side of the front coupler 31. Then the pressing plate 33 is covered above the rubber joint 1, and the bolt penetrates through the pressing plate 33 and the front hook body 311 to press the rubber joint 1 in the front hook cavity 313. Finally, the pin 23 is sequentially passed through the shaft mounting hole 324 of the upper rear hook end plate 322, the plate body through hole 331, the inner ring through hole 221 and the shaft mounting hole 324 of the lower rear hook end plate 322 from top to bottom, and the cotter pin 24 is passed through the through hole at the lower end of the shaft body 232, so that the rear coupler 32 is hinged on the pin 23 of the metal knuckle. So far, the front coupler 31, the rubber joint 1, the metal joint and the rear coupler 32 are sequentially connected to form a composite connection coupler.
The metal joint in the composite joint of the embodiment mainly provides large-angle deflection capability and small deflection rigidity in the axial direction, and the rubber joint 1 in the composite joint mainly provides good radial buffering performance and small radial rigidity. For example: the front coupler 31 of the composite connection coupler of the embodiment is connected with one carriage, the rear coupler 32 is connected with the other carriage, when a vehicle turns, the two couplers can rotate relatively, and the vehicle can turn in a small radius due to the metal joint in the composite joint. And the rubber joint 1 in the composite joint can provide good buffering performance during the starting and braking of the vehicle under a large load.
Specifically, when the coupler of the rear car is hinged on the pin 23 and the composite knuckle is installed in the coupler of the front car, the good damping performance provided by the rubber knuckle 1 when the vehicle is emergently braked under a large load is realized by the following principle: the rear car will push the pin 23 forward through the rear coupler 32 due to inertia, causing the metal knuckle to push the intermediate deck forward. At this time, since the outer sides of the auxiliary ring 18, the upper end plate 11, and the lower end plate 12 all abut against the inner side of the front coupler 31 of the front car, the metal knuckle moves relative to the rubber knuckle 1 in the radial direction. During the relative movement, firstly, the upper rubber body 13 and the lower rubber body 14 generate shearing deformation to provide damping force, so as to play a role of buffering. As the metal knuckle moves further relative to the rubber knuckle 1, the outer side of the diaphragm 16 abuts against the auxiliary ring 18, and since the auxiliary ring 18 is made of an elastic material, when the diaphragm 16 presses the auxiliary ring 18 forward, the auxiliary ring 18 deforms to provide a damping force, and further plays a role in buffering. However, since the auxiliary ring 18 abuts against the inner side of the front coupler 31, the auxiliary ring 18 is difficult to be further compressed after being compressed to a certain extent, and at this time, the auxiliary ring 18 and the front coupler 31 form a hard stop function together, so that the composite knuckle has variable rigidity, the rigidity is greatly improved, and the metal knuckle can be prevented from moving forward relative to the rubber knuckle 1.
It will be apparent that modifications and variations are possible without departing from the principles of the invention as set forth herein.
