Abstract
The invention relates to a dual-mode wedge for a bogie damping device. The dual-mode wedge is characterized by comprising a wedge body; the top surface and the bottom surface of the wedge body are parallel with each other; two cavities used for containing first springs are formed in the wedge body, two through holes are formed in the bottom surface of the wedge body, and each through hole right faces one cavity; and a round navel used for installing a second spring is arranged in the middle of the bottom surface of the wedge body. Due to the fact that the first springs having a certain pre-compression amount can be arranged in the two cavities respectively, and meanwhile the second spring is arranged at the bottom, the dual-mode wedge can provide larger damping force unrelated to the dead weight of a wagon body when a wagon is empty, and also can provide corresponding damping force along with increasing of the load weight of the wagon; and in other words, the dual-mode wedge can play a role of a constant-friction damping device and a role of a variable-friction damping device at the same time.
Description
Technical field
The present invention relates to a kind of parts for truck damping device, be specifically related to a kind of double mode wedge for truck damping device.
Background technology
The shock attenuation unit be used at present on railway goods train bogie mostly is and becomes friction damping device or normal friction damping device.These two kinds of shock attenuation units have respective feature, but also have obvious shortcoming.The friction force that becoming friction damping device can provide increases, the phenomenon of the stability that empty wagons then can be caused to run for the vehicle that the less load-carrying of dead weight of vehicle is larger and stationarity proportion car poor performance along with the load-carrying increase of vehicle.Normal friction damping device provides constant friction force for empty and load, excessive relative to damping force empty wagons, and not enough to loaded vehicle friction force.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of double mode wedge for truck damping device, it coordinates damper spring to can be assembled into bimodulus shock attenuation unit, and this shock attenuation unit all can provide suitable frictional power under empty wagons and loaded vehicle state.
For achieving the above object, the present invention is by the following technical solutions: a kind of double mode wedge for truck damping device, it is characterized in that: it comprises a wedge body, end face and the bottom surface of described wedge body are parallel to each other, two are provided with for holding the cavity of the first spring in the inside of described wedge body, offer two through hole in described wedge body bottom surface, described in through hole described in each and, cavity is just right; One is provided with for installing the round navel of the second spring in the middle part of the bottom surface of described wedge body.
One is arranged respectively for carrying out with bolster the auxiliary hole assembled in the both sides of described wedge body.
The inclined-plane of described wedge body is plane or cambered surface.
The inclined-plane of described wedge body is provided with a groove.
Described wedge body is cast structure.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention can arrange the first spring that has certain pre compressed magnitude respectively in two cavitys, one second spring is set in bottom simultaneously, therefore larger damping force can be provided when empty wagons, conduct oneself with dignity irrelevant with car body, and along with the increase of vehicle load, corresponding damping force can be provided again, namely the present invention can play normal friction damping device simultaneously and become the effect of friction damping device.2, structure of the present invention is simple and ingenious, with low cost, is easy to processing.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present invention;
Fig. 2 is elevational schematic view of the present invention;
Fig. 3 is the schematic diagram of using state of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1 and Figure 2, the present invention includes a wedge body 1, end face and the bottom surface of wedge body 1 are parallel to each other, and are provided with two for holding the cavity 2 of the first spring 8 in the inside of wedge body 1, offer two through hole 3 in wedge body 1 bottom surface, each through hole 3 and a cavity 2 just right.One is provided with for installing the round navel 4 of the second spring 9 in the middle part of the bottom surface of wedge body 1.
In above-described embodiment, an auxiliary hole 5 is set respectively, for assembling with bolster in the both sides of wedge body 1.
In above-described embodiment, the inclined-plane of wedge body 1 can be plane, also can be cambered surface.
In above-described embodiment, the inclined-plane of wedge body 1 is provided with a groove 6, its effect has two: one to be arrange groove 6 inclined-plane of wedge body 1 can be made to split into multiple less face, is easy to processing like this when adopting casting; Two is that groove 6 surrounding can form raised structures, and raised structures can play the effect weighing limit of wear, and namely when jut wears up to concordant with groove 6 in use for some time, then the abrasion representing wedge body 1 reach the limit of.In above-described embodiment, wedge body 1 adopts cast structure.
The present invention in use, one first spring 8 is installed respectively in two cavitys 2, the bottom of the first spring passes from through hole 3, sheathed one second spring 9 on circle navel 4 again, and the first spring realizes certain pre compressed magnitude by means of bolster 7, now provided friction force is identical with normal friction shock absorber effect.Along with the increase of load, the second spring 9 be positioned at bottom wedge body 1 is also compressed, and makes the friction force of the main friction face of wedge body 1 increase along with the second spring 9 amount of deflection and increase.The advantage of this double mode vibration damping can provide when empty wagons to hand over large damping force, conducts oneself with dignity irrelevant with car body.And along with the increase of vehicle load, corresponding damping force can be provided again.
The present invention is only described with above-described embodiment, and the structure of each parts, setting position and connection thereof all can change to some extent.On the basis of technical solution of the present invention, all improvement of carrying out individual part according to the principle of the invention or equivalents, all should not get rid of outside protection scope of the present invention.
