While with the contact area of backing plate so as to reduce goat to the pull force of tongue, moreover it is possible to avoid other structures issuable
The problem of stress concentration.
Optionally, 2mm is widened on the non-work side of rail head 50.Rail head 50 after widening is sturdy, and abrasion-resistance is strong, so as to reduce dimension
Shield.
As shown in Fig. 2 offering limited impression 21 at heel end 20, limited impression 21 is used to coordinate limitation heel end with installed part
20 movement.By the cooperation of installed part and limited impression 21, heel of switch rail 20 is fixed on a firmware, so as to prevent
Heel end 20 is beated.Optionally, limited impression 21 is semicircle, with the shape adaptation with installed part.Firmware can be interval iron.
The tongue of embodiment one is made up of bainitic steel material.Bainitic steel is easily obtained, and in production can add heat
Work molding procedure merges with thermal quenching process, and air cooling eliminates quenching process from hard, has not only saved the energy, has simplified technique
With improve production efficiency, and can avoid due to the heat treating fault such as strain cracking and oxidation and decarbonization caused by quenching.Phase
It is relatively low using the firm cost of bainite than the tongue of the alloy square steel manufacture in existing use high intensity, and processing tongue
Technique is simpler, and the cycle for processing tongue is also relatively short, it is often more important that, using the tongue of Pattern Bainite Alloy steel making, firmly
Degree is up to 400HB, and abrasion resisting ability is strong.High intensity, high rigidity and the excellent wearability of bainitic steel, are expected to its future
Promoted the use of in orbit instead of the alloy square steel of high intensity.
Optionally, tongue is AT tongues.AT tongues globality is strong, and rigidity is big, and section is sturdy, and stress is superior, carrying
Ability is strong, and stability is good, and haunch Gu tripe phenomenons are less prone in use, and maintenance amount is small.
The utility model additionally provides the (not shown) of embodiment two of tongue, the difference of embodiment two and embodiment one
Be, in embodiment two, the both sides of the flange of rail 30 offer friction escape groove 31, thus further reduce the flange of rail 30 and backing plate it
Between contact area.Contact area further reduces, and the frictional force that tongue is subject to when moving further reduces, so as to enter one
Step reduces pull force of the goat to tongue.Optionally, due to the narrowed width of the flange of rail 30, elastic bendable type structure is formed, is had
Beneficial to realize bend become rail.Optionally, friction escape groove 31 can be formed by the method to the progress milling of the flange of rail 30.
Identical with embodiment one, the first end of tongue forms tip 10, and the second end of tongue forms heel end 20, and heel end 20 is
Diagonal joint, is connected with the guide rail of diagonal joint.In the prior art, heel end 20 is vertical joint, in the guide rail with vertical joint
After overlap joint, produce vertical connecting sewing between heel end 20 and guide rail, wheel from heel of switch rail 20 move on guide rail when, by vertical
Connecting sewing can produce vibration and noise, and then electric car is shaken, and influence riding comfort.The heel of switch rail 20 of diagonal joint with
The Slidway lap of diagonal joint, wheel can be from tongue gentle transition to guide rail on, wheel through inclination connecting sewing when oscillation phenomenon
Mitigate, effect of vibration and noise reduction is obvious, so as to improve the comfortableness of seating.
Optionally, the angle between the end face of diagonal joint and side is between 30 °~60 °.In embodiment one, diagonal joint
Angle theta between end face and side is 45 °.The heel end 20 of diagonal joint not only contributes to vibration and noise reducing, the abrasion loss of heel end 20 itself
Also it is smaller, it is easy to safeguard.
In embodiment two, friction escape groove 31 is also deep-slotted chip breaker.Curved slot arrangement, can reduce tongue and backing plate
While contact area is so as to reduce goat to the pull force of tongue, moreover it is possible to avoid the issuable stress concentration of other structures
The problem of.
Optionally, 2mm is widened on the non-work side of rail head 50.Rail head 50 after widening is sturdy, and abrasion-resistance is strong, so as to reduce dimension
Shield.
It is identical with embodiment one, in embodiment two, limited impression 21 is offered at heel end 20, limited impression 21 is used for and peace
Piece installing coordinates the movement of limitation heel end 20.By the cooperation of installed part and limited impression 21, heel of switch rail 20 is fixed to one
On firmware, so as to prevent heel end 20 from beating.Optionally, limited impression 21 is semicircle, with the shape adaptation with installed part.Surely
Firmware can be interval iron.
Tongue in embodiment two is also made up of bainitic steel material.Bainitic steel is easily obtained, in production can be by
Thermo forming process merges with thermal quenching process, and air cooling eliminates quenching process from hard, has not only saved the energy, has simplified
Technique and improve production efficiency, and can avoid because the heat treatment such as strain cracking and oxidation and decarbonization lacks caused by quenching
Fall into.The tongue manufactured compared to the alloy square steel of existing use high intensity, it is relatively low using the firm cost of bainite, and processing point
The technique of rail is simpler, and the cycle for processing tongue is also relatively short, it is often more important that, using the point of Pattern Bainite Alloy steel making
Rail, hardness is up to 400HB, and abrasion resisting ability is strong.High intensity, high rigidity and the excellent wearability of bainitic steel, make it not
To be expected to replace the alloy square steel of high intensity to promote the use of in orbit.
Optionally, tongue is AT tongues.AT tongues globality is strong, and rigidity is big, and section is sturdy, and stress is superior, carrying
Ability is strong, and stability is good, and haunch Gu tripe phenomenons are less prone in use, and maintenance amount is small.
Optionally, the junction of the web of the rail 40 and rail head 50 passes through the first arcuate structure transition, and/or the web of the rail 40 and the flange of rail 30
Junction pass through the second arcuate structure transition.By arcuate structure transition, the stress concentration situation of junction can be slowed down, from
And prevent that slight crack from occurring in tongue its junction during long-term use, it is ensured that traffic safety.
As can be seen from the above description, the utility model the above embodiments realize following technique effect：
The heel of switch rail of diagonal joint and the Slidway lap of diagonal joint, wheel can be from tongue gentle transition to guide rail on, car
Oscillation phenomenon mitigates when wheel is by tilting connecting sewing, and effect of vibration and noise reduction is obvious, so as to improve the comfortableness of seating.
