Abstract
The invention discloses a train rail capable of reducing noise and vibration. The train rail comprises a rail body, connecting parts and connecting bodies, wherein the connecting parts are arranged at the two ends of the rail body, and the connecting bodies are arranged on the tops of the connecting parts. Each connecting part comprises a first connector and a second connector which is matched with the first connector, wherein the first connector and a second connector of another rail are connected in a convex-concave mode or are meshed in a step mode, and the top of the first connector and the top of the second connector are provided with steps which are lower than the rail body. The connecting bodies wrap the tops of the steps and are flush with the top of the rail body. The vibration and noise between a train and the rail can be reduced, the comfort for driving the train is improved, the train passing resistance is reduced, the service life of the rail is prolonged, the maintenance cost of the rail is reduced, and manpower and financial resources are saved.
Description
Technical field
The present invention relates to a kind of rail, relate in particular to a kind of rail that reduces noise and concussion.
Background technology
The advantages such as along with social development, traffic is also more and more flourishing, and railway transportation relies on its conveying capacity strong, and the low and speed of cost is fast, therefore become the main machining tool in a lot of areas.But traditional rail in use, for preventing from can being provided with because of the joint that variations in temperature produces the rail that joins at two tack while making rail distortion lay rail of expanding with heat and contract with cold the gap of certain width, the heavy-loaded line angle direction that the angle in gap contacts with rail with wheel is consistent and parallel to each other, therefore when wheel grinds gap, fell in gap, and caused and clash into and send noise.Owing to there being gap between rail, not only affect passengers inside the car's rest and work, and increasing train resistance, limited further raising train speed, also easily cause the damage of train Parts, shorten rail application life, increased the operation cost of train, caused the waste of huge human and financial resources.
Summary of the invention
For the defect existing in prior art and deficiency, the object of this invention is to provide a kind of rail that reduces noise and concussion, it can reduce concussion and noise between train and rail, improves train running comfort level, extend rail application life, reduce train operation cost.
For achieving the above object, the present invention adopts following technical scheme:
Reduce a rail for noise and concussion, comprise rail body, be arranged on the connecting portion at described rail body two ends and be arranged on the connector at described connecting portion top, wherein,
Described connecting portion comprise the first joint and with suitable the second joint of described the first joint, described the first joint is with the second joint of another root rail that convex-concave shape is connected or stepped engagement;
The top of described the first joint and described the second joint has step, and described step is lower than described rail body;
Described connector is wrapped in the top of described step, and concordant with the top of described rail body.
Further, the coefficient of thermal expansion and contraction of described connector is less than rail body coefficient of thermal expansion and contraction.
Further, described connector is formed by the casting of high-strength wearable Alcoa.
The rail of minimizing noise provided by the invention and concussion, by improving the connected mode flushing of traditional rail and cover the connector that coefficient of thermal expansion and contraction is less on link position, reduce concussion and noise between train and rail, improve train running comfort level, reduced car resistance, extend rail application life, thereby reduced the upkeep cost of rail, saved human and financial resources.

Fig. 1 is the preferred rail connecting portion of the present invention structural representation.
Fig. 2 is another preferred rail connecting portion structural representation of the present invention.
Fig. 3 is the preferred rail connector structural representation of the present invention one.
Fig. 4 is the preferred rail connecting portion cross-sectional view of the present invention one
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Below in conjunction with accompanying drawing, by specific embodiment, the invention will be further described:
With reference to figure 1-3, comprise rail body 1, the connecting portion 2 at body two ends is in-orbit set and is arranged on the connector 3 at connecting portion top 2, wherein, described connecting portion comprise the first joint 21 and with suitable the second joint 22 of the first joint 21, the first joint 21 and the second joint 22 of another root rail are to convex-concave shape is connected or stepped engagement; The top of the first joint 21 and the second joint 22 has step 23, and step 23 is lower than rail body 1; Connector 3 is wrapped in the top of step 3, and concordant with the top of rail body 1.
During use, the first joint 21 protuberance intercalations are meshed together in the recess of the second joint 22 of another root rail or by the first joint 21 and the stepped joint of the second joint 22 of another root rail, at the step 23 top parcel connectors of connecting portion 2.
The present invention is by improving the connected mode flushing of traditional rail, make it both in the flexible direction of rail, leave gap, meet the requirement of expanding with heat and contract with cold, do not overlap completely with wheel path again, while making cartwheel roll cross gap, always there is part rail support wheel, and at the top of connecting portion parcel connector, this connector is concordant with rail body, therefore wheel can pass through rail clearance more reposefully, reduce concussion and noise between train and rail, improve train running comfort level, reduced car resistance, extend rail application life, thereby reduced the upkeep cost of rail, human and financial resources have been saved.
As a preferred embodiment of the present invention, for casting the coefficient of thermal expansion and contraction of metallic interconnect materials, be less than rail body coefficient of thermal expansion and contraction, for example, connector is by high-strength wearable Alcoa, for example its alloy composition (% by weight) is Si1.0-50.0, Fe0.5-10.0, Cu0.1-5.0, Mg0.01-5.0, La0.01-3.0, Ce0.01-3.0, surplus is that the aluminium alloys of A is made, can further reduce the issuable gap of seam crossing, wheel can be passed through more reposefully, reduce collision, thereby reduce concussion and the noise between train and rail.
The present invention has reduced noise and concussion by improving the connected mode flushing of traditional rail, make passenger have comfortable environment by bus, the resident of railway both sides also avoids noise puzzlement, can also reduce concussion and the resistance of train simultaneously, has widened the transport field of train and has contributed to train speed-raising; In addition, the present invention has also extended the application life of train wheel and rail, has reduced the upkeep cost of rail, has saved human and financial resources.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of the claims in the present invention.
