Abstract
The utility model relates to an oblique joint rail. The rail joint cross section 1 of the exciting railway forms an included angle of 45 DEG with the rail side surface 3, and forms an included angle of 135 DEG with the rail side surface 4. A rail gap 5 forms an included angle of 45 DEG with the motion direction of train wheels. The utility model avoids the breakage of wheels and rails on the contact rail gap parts, and thus the utility model reduces the impact force of the wheels and the rails on the contact rail gap parts, extends the service lives of the rails, and is favorable to enhance the train speed.
Description
The utility model is a kind of diagonal joint rail that is used for railroad track.
The rail of railroad track use now, the angle of its joint section and rail extending direction is 90 °, and because the influence of rail stroke amount, the rail joint part must leave the rail gap of certain width.To moment of rail gap, rail gap makes the wheel track contact be interrupted at this place at wheel rolling, and the big more this influence of rail gap is big more, and this is that the joint produces a reason of adding percussion; Another reason is to close on the moment of rail gap at wheel rolling, the two rail ends changing of the relative positions relatively up and down form step, the step discrepancy in elevation on the general circuit is 0.02cm, when wheel contacts with it, produce impingement phenomenon, under this impact force action, track generation forced vibration, this vibration has bigger destruction to track.
The purpose of this utility model is the diagonal joint rail that impingement phenomenon between a kind of blank area that can improve existing common plain adapter Rail for railway and train wheel will be provided.
Solution of the present utility model be the joint section of rail is made and the rail extending direction between angle be acute angle, desirable angle is 45 °, make the angle between the rail gap and the train wheel direction of motion be 45, avoided the interruption of wheel track contact at the rail gap place, thereby reduce the impact of wheel track at the rail gap place, prolong the application life of rail, also help improving the train speed of a motor vehicle.
Below in conjunction with accompanying drawing the utility model is specified:
Accompanying drawing is the utility model structural representation.
The utility model is by rail joint section 1, rail rail level 2, and rail side 3, rail side 4 constitutes.The rail joint section 1 at rail two ends is a parallel surface, 2 angles of joint section 1 and rail rail level are 90 ° of angles, be 45 with rail side 3 angles, be 135 ° of angles with rail side 4 angles, be that angle is 45 between the extending direction of rail gap 5 and rail, like this, arrive the moment of rail gap 5 at train wheel rolling, train wheel will be pressed on the track rail level 2 at rail gap 5 two ends simultaneously, avoided existing railroad track to make the phenomenon of wheel track contact discontinuity at the rail gap place, also making simultaneously the relative changing of the relative positions up and down of two rail ends form step reduces, eliminated the consequent additional percussion that produces at the rail joint place, played and reduce track vibration, the effect that prolongs rail application life and help improving the train speed of a motor vehicle.
Rail material, length and other structure are identical with the standard rail that requires to use with present railway.
Claims (2)
1, a kind of diagonal joint rail, by rail joint section 1, rail rail level 2, rail side 3,4 constitutes, and it is characterized in that: the rail joint section 1 at rail two ends is parallel surface, with rail rail level 2 angles be 90 ° of angles, with rail side 3 angles be acute angle, with rail side 4 angles be the obtuse angle.
2, rail according to claim 1 is characterized in that: the desirable angle of rail joint section 1 and rail side angle be with rail side 3 angles be 45, with rail side 4 angles be 135 ° of angles.
