The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, car body truck journal box damper mechanism is arranged on each truck journal box and arranged on left and right sides, it is formed 1 except comprising the basic spring that is arranged on the vehicle frame, in the prior art, have plenty of to form on 1 wearing plate be set at spring, by setting then be that the wedge of rigidity is formed.These frame modes all can not be controlled the location of axle box well.
The truck journal box damper mechanism that the utility model provides, what be provided with on spring composition 1 then is that the elasticity wedge forms 2.Shown in Fig. 2～4, the elasticity wedge is formed 2 and mainly is made up of wedge body 3, main friction shoe 4, main friction seat 5, elasticity locating piece 6, auxiliary friction plate 7 etc.One side of the close axle box of wedge body 3 (as shown in Figure 3) offers the open recess of level, and the opening surface of groove is to axle box, and the bottom of groove offers pinned hole, and elasticity locating piece 6, main friction seat 5 and main friction shoe 4 center separately also all offer pinned hole.In groove, outside from the bottom, be assembled with elasticity locating piece 6, main friction seat 5 and main friction shoe 4 successively, wherein main friction shoe 4 expose outside the groove and and groove between leave certain interval, assembling mode is to pass main friction shoe 4, main friction seat 5, elasticity locating piece 6 and groove successively by a spring cotter 8, and main friction shoe 4, main friction seat 5 and elasticity locating piece 6 are positioned on the wedge body 3.On the inclined-plane, top of wedge body 3, assemble an auxiliary friction plate 7, auxiliary friction plate 7 is provided with along the dip plane of wedge body 3, in the auxiliary friction plate 7 conductive pole is housed.
In the utility model, during prefabricated elasticity locating piece 6, in the monoblock elastic body, can press from both sides and establish parallel several block plates, the monoblock elastic body is divided into some stratiforms, pinned hole is also all arranged on every block plate.When elasticity locating piece 6 was encased in the groove, steel plate was vertical state and places.
In the utility model, the contact surface of main friction shoe 4 and main friction seat 5 corresponds to concave spherical surface and protruding sphere, and wherein main friction shoe 4 is protruding sphere, and main friction seat 5 is concave spherical surface (as shown in Figure 5), and their contact is the sphere contact.This ball-type damascene structures can help multidirectional location.
