Further, described bearing pin is the bearing pin of end with pin-and-hole, be assemblied in the bearing pin in the first spherical plain bearing rod end to be connected with the control lever of height adjusting valve, for preventing in locomotive operation process because vibration makes bearing pin get loose with control lever, bearing pin adopts hexagon slotted nut fastening with control lever, in the pin-and-hole of end part of pin shaft, plug spring cotter after fastening, preventing from being threaded gets loose; Be assemblied in the bearing pin in the second spherical plain bearing rod end and the framework mount pad on bogie truck adopts hexagon slotted nut to be fastenedly connected, after fastening, in the pin-and-hole of end part of pin shaft, plug spring cotter.
In order to antirust, non-maintaining and have higher service life, first, second spherical plain bearing rod end described and spiral shell bucket adopt stainless steel material.
The beneficial effects of the utility model are:
1. have employed the long shorter upper and lower screw rod of bar, the spiral shell bucket large by rigidity docks with upper and lower screw rod, and structure compared to existing technology increases integrally-built rigidity, avoids the moderate finite deformation that insufficient rigidity causes, the needs of vehicle by small curve radius can be met, wide adaptability.
2. dihedral ball-joint has been replaced to flake joint self-lubricating rod end spherical plain, the advantage brought by this spherical plain bearing rod end self structure, made structural safety reliable, there will not be case accident, and can be implemented in whole whole of life non-maintaining.
3. upper and lower screw rod and spiral shell bucket are equipped with bayonet socket, very convenient when adjusting with spanner.
4. first, second spherical plain bearing rod end and spiral shell bucket adopt stainless steel material, do not need the maintenance processes such as rust cleaning.
5. very convenient when the unit design of height regulating rod makes mounting and adjusting, only upper and lower screw rod spanner need be fixed, namely can conveniently by the length rotating spiral shell bucket and regulate upper and lower screw rod simultaneously.
