Abstract
The utility model provides a novel track traffic rubber bush, relates to rubber bush technical field, its characterized in that: including inner frame, the rubber body and outer skeleton, the mid portion of inner frame set up to the sphere, rubber body parcel in the outside of the sphere of inner frame, outer skeleton parcel in the outside of the rubber body, the both ends thickness of outer skeleton thickness and the both ends in the middle of being greater than go on excessively through the inclined plane with the centre, thickness in the middle of being greater than of the both ends thickness of the rubber body and inboard for the sphere, the outside of the rubber body set to with outer skeleton inboard matched with inclined plane. The utility model discloses an inner frame is lived to rubber bush's outer skeleton parcel, reaches axial rigidity greatly increased and improves stably. And the inner frame is escaped, avoid that the incident appears in the locomotive under the overstrain condition in can not following outer skeleton.
Description
Technical field:
The utility model relates to rubber bushing technical field, specifically a kind of novel track traffic rubber bushing.
Background technique:
Existing track traffic rubber bushing in use, because lining axial rigidity is lower, locomotive occurs that in movement process transverse judder is comparatively large, and when there is axial load factor, inner frame departs from from purchasing ore, affects the stability of locomotive, Security and travelling comfort like this.And because the radial rigidity of track traffic rubber bushing is large, swing angle is large, and inner frame plunger encapsulate face adopts sphere, causes the rubber thickness deviation between interior purchasing ore to cause very greatly greatly reduce the working life of rubber bushing.
Model utility content:
The technical problems to be solved in the utility model is to provide a kind of track traffic rubber bushing, when not changing radial rigidity, greatly improves axial rigidity.In addition, the conformity of inside and outside skeleton rubber thickness is improved.
Solve technical problem adopt following technological scheme:
A kind of novel track traffic rubber bushing, it is characterized in that: comprise inner frame, rubber body and purchasing ore, the intermediate portion of described inner frame is set to sphere, described rubber body is wrapped in the outside of the sphere of inner frame, described purchasing ore is wrapped in the outside of rubber body, the two-end thickness of described purchasing ore is greater than middle thickness and two ends are undertaken excessively with middle by inclined-plane, the two-end thickness of described rubber body is greater than middle thickness and inner side is sphere, and the arranged outside of rubber body becomes and the inclined-plane matched inside purchasing ore.
Described purchasing ore becomes and is symmetrical arranged.
The sphere of described inner frame and joint, two ends are provided with step and carry out excessively.
Purchasing ore of the present invention is designed to the inclined-plane of big at both ends and small in middle, through undergauge after sulfuration, the cut-off at two ends is more much bigger than middle cut-off, it is more severe that the two ends internal diameter of such purchasing ore can contract, and under the vulcanization of rubber body, now the two ends of purchasing ore just by the sphere position of inner frame tightly be wrapped in purchasing ore inside, just prevent inner frame from escaping from purchasing ore so on the one hand, while not affecting radial rigidity, axial rigidity can increase greatly on the other hand.
The beneficial effects of the utility model are: the utility model wraps inner frame by the purchasing ore of rubber bushing, reach axial rigidity greatly increase improve stable.And inner frame can not be escaped from purchasing ore, locomotive is in the event of overloading avoided to occur security incident.
Accompanying drawing illustrates:
Fig. 1 is schematic diagram before track traffic rubber bushing undergauge of the present utility model.
Fig. 2 is finished product schematic diagram after track traffic rubber bushing undergauge of the present utility model.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As illustrated in fig. 1 and 2, a kind of novel track traffic rubber bushing, comprise inner frame 1, rubber body 2 and purchasing ore 3, the intermediate portion of inner frame 1 is set to sphere 4, rubber body 2 is wrapped in the outside of the sphere 4 of inner frame 1, purchasing ore 3 is wrapped in the outside of rubber body 2, the two-end thickness of purchasing ore 3 is greater than middle thickness and two ends are undertaken excessively with middle by inclined-plane, the two-end thickness of rubber body 2 is greater than middle thickness and inner side is sphere, and the arranged outside of rubber body 2 becomes and the inclined-plane matched inside purchasing ore 3.Purchasing ore 3 becomes and is symmetrical arranged.Sphere 4 and the joint, two ends of inner frame 1 are provided with step 5 and carry out excessively.
Rubber bushing is before undergauge, and purchasing ore 3 is designed to the inclined-plane of big at both ends and small in middle, and through undergauge, the cut-off at the two ends of purchasing ore 3 is more much bigger than middle cut-off, and it is more severe that the two ends internal diameter of purchasing ore 3 also contracts simultaneously.Situation after undergauge is as Fig. 2, and the two ends minimum diameter of purchasing ore 3 is more additional than the sphere of inner frame 1 little many, the two ends of purchasing ore 3 just by the sphere position of inner frame 1 tightly to be wrapped in purchasing ore 3 inner.And the thickness between purchasing ore 3 and inner frame 1 of the rubber body 2 after undergauge is also relatively more even, stressed basically identical in unit area.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
