Definitions
- the present invention relates to an elastic side bearing assembly system for railway vehicles, and belongs to the technical field of a locomotive vehicle.
- the elastic side bearing assembly system is widely used in bogies for railway vehicles. There is a longitudinal gap between a side bearing body and a side bearing seat in a conventional elastic side bearing assembly system, during operation, the side bearing body and the side bearing seat rub against and collide with one another constantly, so that the side bearing body and the side bearing seat are easily damaged and need to replace the wear plate frequently, which is wasteful and increases maintenance work.
- the present invention provides an elastic side bearing assembly system for railway vehicles, capable of providing good longitudinal positioning between a side bearing body and a side bearing seat and achieving wear-free.
- the present invention provides an elastic side bearing assembly system for railway vehicles, including a side bearing body and a side bearing seat, further including a first ball hinge assembly, a connecting rod and a second ball hinge assembly, the side bearing body is connected to the side bearing seat via the first ball hinge assembly, the connecting rod and the second ball hinge assembly, the first ball hinge assembly is provided below one end of the side bearing body, the second ball hinge assembly is provided above the side bearing seat at a different end with respect to the first ball hinge assembly, the first ball hinge assembly is connected to the second ball hinge assembly via the connecting rod; side bearing springs are provided between the side bearing body and the side bearing seat, stoppers are provided above the side bearing seat, and the side bearing springs are connected to the side bearing body and the side bearing seat respectively by extending through the stoppers; a side bearing wear plate is provided above the side bearing body.
- the side bearing springs are steel springs or rubber springs.
- the number of the steel springs is two or four.
- the number of the rubber springs is two.
- the side bearing wear plate is made of a wear-resistant steel plate or an organic polymeric material.
- the first ball hinge assembly is connected to the side bearing body by welding or bolting
- the second ball hinge assembly is connected to the side bearing seat by welding or bolting
- the first ball hinge assembly and the second ball hinge assembly are connected to the connecting rod by thread fitting or bolt hole.
- the present invention has the beneficial effects as follows: the side bearing body is connected to the side bearing seat via two ball hinge assembles and the connecting rod, which guarantees that there is no longitudinal gap between the side bearing body and the side bearing seat during operation of the vehicle, achieves stable performance, wear-free, high reliability, long travel stroke, increases pre-compression of the elastic side bearing, and thereby improves working stability of the elastic side bearing and has advantages of a simple and compact structure and convenient installation.
- FIG. 1 is a schematic structural diagram according to the present invention
- FIG. 2 a is a schematic structural diagram of a connecting rod via thread fitting connection according to the present invention.
- FIG. 2 b is a schematic structural diagram of a connecting rod via bolt hole connection according to the present invention.
- FIG. 3 is a schematic structural diagram according to Embodiment 1 of the present invention.
- FIG. 4 is a schematic structural diagram according to Embodiment 2 of the present invention.
- FIG. 1 is a schematic structural diagram according to the present invention.
- the system in the present invention includes a side bearing body 3 , a side bearing seat 1 , a first ball hinge assembly 2 , a connecting rod 7 and a second ball hinge assembly 8 .
- the side bearing body 3 is connected to the side bearing seat 1 via the first ball hinge assembly 2 , the connecting rod 7 and the second ball hinge assembly 8 , so that there is no longitudinal gap between the side bearing body 3 and the side bearing seat 1 , thereby good longitudinal positioning can be achieved.
- the first ball hinge assembly 2 is provided below one end of the side bearing body 3
- the second ball hinge assembly 8 is provided above the side bearing seat 1 at a different end with respect to the first ball hinge assembly 2
- the first ball hinge assembly 2 is connected to the second ball hinge assembly 8 via the connecting rod 7 .
- Side bearing springs 5 are provided between the side bearing body 3 and the side bearing seat 1 , stoppers 6 are provided above the side bearing seat 1 , and the side bearing springs 5 are connected to the side bearing body 3 and the side bearing seat 1 respectively by extending through the stoppers 6 , such an arrangement makes the elastic side bearing assembly have a long travel stroke, which increases pre-compression of the elastic side bearing, and thereby further improves working stability of the elastic side bearing.
- a side bearing wear plate 4 is provided above the side bearing body 3 .
- the side bearing springs 5 are steel springs or rubber springs.
- FIG. 1 is a schematic diagram of two steel springs, and the two steel springs are arranged in parallel.
- FIG. 3 is a schematic diagram of four steel springs, and the four steel springs are divided into two sets, that is, one set of two large springs, and one set of two small springs, and the two sets of steel springs are arranged in parallel, such an arrangement increases the pressure, and makes the side bearing body 3 more stable.
- FIG. 4 is a schematic diagram of rubber side bearing springs 5 .
- the side bearing wear plate 4 is made of a wear-resistant steel plate or an organic polymeric material.
- the first ball hinge assembly 2 is connected to the side bearing body 3 by welding or bolting
- the second ball hinge assembly 8 is connected to the side bearing seat 1 by welding or bolting.
- the first ball hinge assembly 2 and the second ball hinge assembly 8 are connected to the connecting rod 7 by threaded fitting or bolt holes.
- FIG. 2 a is a schematic diagram of thread fitting connection between a connecting rod and two ball hinge assembles.
- FIG. 2 b is a schematic diagram of bolt hole connection between a connecting rod and two ball hinge assembles.
- the stoppers 6 are connected to the side bearing seat 1 by welding or bolting.
- the side bearing body is connected to the side bearing seat via two ball hinge assembles and the connecting rod, guaranteeing that there is no longitudinal gap between the side bearing body and the side bearing seat during operation of the vehicle, achieving stable performance and wear-free during operation of the vehicle, thus extending service life of the elastic side bearing assembly and reducing maintenance cost.
- the present invention also has high reliability and long travel stroke, increases pre-compression of the elastic side bearing, and thereby improves working stability of the elastic side bearing and has advantages of simple and compact structure as well as convenient installation.
