Description
Technical field
The present invention relates to a kind of rolling stock anticreep bogie truck, belong to railway equipment manufacturing technology field.
Background technology
The under-carriage of rolling stock is connected with bogie truck by center pin, thereby realizes the support of bogie truck to under-carriage, and makes under-carriage have steering capability flexibly.Existing under-carriage is only connected by center pin with bogie truck, bogie truck and under-carriage are synchronized with the movement, other spacing and coupling assemblings are not set, safe not in the process that is combined in transportation and operation between bogie truck and under-carriage, jolt or the road of certain slope on there is the risk getting loose, and on bend, also exist bogie truck to be subject to the risk of rotatory inertia effect generation excessive deflection.Therefore, need to make improvement to existing bogie truck, set up rational limit connector, to reduce above-mentioned risk.
Summary of the invention
The deficiency that the present invention exists for prior art just, provides a kind of rolling stock anticreep bogie truck, is not affecting under the prerequisite that bogie truck freely turns in permission amplitude, can improve the Bindery security of bogie truck and under-carriage.
For addressing the above problem, the technical solution used in the present invention is as follows:
A rolling stock anticreep bogie truck, comprising: bogie side frame and bolster, and described in being arranged at, shake medioccipital center pin, and between described center pin and described bogie side frame, being also provided with elastic side bearing assembly, described elastic side bearing assembly lower end is arranged on described bolster;
Also comprise limit connector, described limit connector lower end connects described bolster, and the junction of described limit connector lower end and bolster is between described elastic side bearing assembly and described bogie side frame, and described limit connector upper end is used for connecting under-carriage; Diff-H between the top and bottom of described limit connector and horizontal throw can change in preset range.
Limit the diff-H that diff-H between the top and bottom of described limit connector limits under-carriage and bogie truck, therefore can effectively reduce bogie truck and under-carriage jolt or the road of certain slope on the risk that gets loose; Limit the relative deflection amplitude that horizontal throw between the top and bottom of described limit connector limits under-carriage and bogie truck, therefore can effectively reduce bogie truck and on bend, be subject to rotatory inertia effect with respect to the risk of under-carriage generation excessive deflection.
As the improvement of technique scheme, the top and bottom of described limit connector are moving fastening, and the lower end of described limit connector is fixedly arranged on described bolster, and the upper end of described limit connector is fixedly arranged on under-carriage.
As the improvement of technique scheme, the lower end of described limit connector is provided with clasp; The upper end of described limit connector is provided with two position limit arms and the connecting rod that is connected two described position limit arms, and two described position limit arms lay respectively at the both sides of described clasp, and described connecting rod is through described clasp.
As the improvement of technique scheme, described clasp place plane is the perpendicular that is parallel to bolster.
Improvement as technique scheme, two described position limit arms are provided with through hole, described connecting rod is through the through hole of two described position limit arms, and described connecting rod one end is provided with limited cap, the described connecting rod other end be provided with screw thread and join with described screw thread and stop nut.
Compared with prior art, implementation result of the present invention is as follows in the present invention:
A kind of rolling stock anticreep bogie truck of the present invention, the limit connector that is arranged at described bolster two ends can not affect bogie truck and freely turn in permission amplitude, can also control with diff-H and the relative deflection amplitude of under-carriage bogie truck, thus reduce bogie truck and under-carriage jolt or the road of certain slope on the risk and the bogie truck that get loose on bend, be subject to rotatory inertia effect with respect to the risk of under-carriage generation excessive deflection; And limit connector is arranged at the outside of the elastic side bearing assembly of supported cart underframe, can prevent that limit connector from counteracting the work of the bogie truck assembly of elastic side bearing assembly and elastic side bearing assembly inner side.And the fastener structures of concrete preferably clasp and connecting rod, there is the processing of being simple and easy to, and mechanical strength is high, the up-and-down movement amplitude of connecting rod in clasp is the diff-H allowed band of bogie truck and under-carriage, and clasp is the spacing scope of relative deflection amplitude of under-carriage and bogie truck to the limited field of connecting rod two end motions.

The specific embodiment
Content of the present invention is described below in conjunction with specific embodiments.
As shown in Figures 1 to 4, be a kind of rolling stock anticreep bogie structure schematic diagram of the present invention.A kind of rolling stock anticreep bogie truck of the present invention, comprise: bogie side frame 1 and bolster 2, and the center pin 3 that is arranged at described bolster 2 middle parts, between described center pin 3 and described bogie side frame 1, being also provided with elastic side bearing assembly 4, described elastic side bearing assembly 4 lower ends are arranged on described bolster 2; Comprise limit connector, described limit connector lower end 5 connects described bolster 2, and the junction of described limit connector lower end 5 and bolster 2 is between described elastic side bearing assembly 4 and described bogie side frame 1, and described limit connector upper end 6 is for connecting under-carriage; The upper end 6 of described limit connector and the diff-H between lower end 5 and horizontal throw can change in preset range.The limit connector that is arranged at described bolster 2 two ends can not affect bogie truck and freely turn in permission amplitude, can also control with diff-H and the relative deflection amplitude of under-carriage bogie truck, thus reduce bogie truck and under-carriage jolt or the road of certain slope on the risk and the bogie truck that get loose on bend, be subject to rotatory inertia effect with respect to the risk of under-carriage generation excessive deflection; And limit connector is arranged at the outside of the elastic side bearing assembly 4 of supported cart underframe, can prevent that limit connector from counteracting the work of the bogie truck assembly of elastic side bearing assembly 4 and elastic side bearing assembly 4 inner sides.
