Abstract
The utility model provides a balanced suspension assembly comprising symmetric balanced bearing hubs and symmetric balanced shaft supports. Communication shafts are connected between each balanced bearing hub and each balanced shaft support. The balanced bearing hubs are supported on the communication shafts through two opposite joint bearings. A protective cover is arranged at the outer ends of the balanced bearing hubs. The shaft section of each communication shaft is provided with an outer thread journal. Each outer thread journal is connected with a slotted nut; the slotted nuts fix the balanced bearing hubs axially. The protective cover is a stamped part formed by stamping a steel board. Due to the fact that the slotted nuts fix the balanced bearing hubs axially, axial interval adjustment of the joint bearings in the balanced bearing hubs is facilitated, and the stability that the balanced bearing hubs are axially fixed to the communication shafts is ensured. The protective cover is the stamped part formed by the steel board, the intensity is greatly improved, the fracture accident can be avoided and lubricating oil is prevented from being leaked.
Description
Technical field
The utility model relates to bogie, especially its balance suspension assembly.
Background technology
A kind of balance suspension assembly of current bogie; as shown in Figure 1; comprise symmetrically arranged equalizer bearing hub 1, symmetrically arranged balance shaft support 2; be connected with connection shaft 3 between equalizer bearing hub 1 and balance shaft support; equalizer bearing hub 1 is supported on connection shaft by two oscillating bearings 7 that arrange in opposite directions; the axial restraint of equalizer bearing hub 1 on connection shaft 3 realized in the end that outer thrust plate 4 is fixed on connection shaft 3 by bolt 5, and the outer end of equalizer bearing hub 1 is provided with over cap 6.The balance suspension assembly of this structure, can not adjust the endplay of oscillating bearing 7, and equalizer bearing hub 1 is under the Action of Gravity Field be subject to from vehicle frame, and oscillating bearing inner ring movement tendency laterally strengthens, and bolt 5 broken end phenomenons often occur, and causes inefficacy.In addition, over cap 6 adopts ironcasting, in use easily breaks, and causes oil leak.
Summary of the invention
In order to improve the axial restraint reliability of equalizer bearing hub on connection shaft, realize the endplay adjustment of oscillating bearing, avoid oil leak, the utility model proposes the balance suspension assembly.
For this reason, the technical solution of the utility model is: the balance suspension assembly, comprise symmetrically arranged equalizer bearing hub, symmetrically arranged balance shaft support, be connected with connection shaft between equalizer bearing hub and balance shaft support, the equalizer bearing hub is supported on connection shaft by two oscillating bearings that arrange in opposite directions, and the outer end of equalizer bearing hub is provided with over cap, it is characterized in that: the shaft part of connection shaft is provided with the outside thread axle journal, be connected with fluted nut on the outside thread axle journal, to equalizer bearing hub axial restraint; Described over cap is the blanked part that adopts Steel Sheet.
Beneficial effect: the utility model to equalizer bearing hub axial restraint, not only facilitates the interior oscillating bearing of equalizer bearing hub in axial gap adjustment by flat fluted nut, can also guarantee the axial restraint reliability of equalizer bearing hub on connection shaft; Over cap adopts steel stamping part, and intensity improves greatly, has stopped the break accident generation, avoids oil leak.
The accompanying drawing explanation
Fig. 1 is the constructional drawing of existing balance suspension assembly.
Fig. 2 is the constructional drawing of the utility model balance suspension assembly.
Shown in figure: 1. equalizer bearing hub; 2. equalizer bearing hub; 3. connection shaft; 4. outer thrust plate; 5. bolt; 6. over cap; 7. oscillating bearing; 8. fluted nut; 9. lock bolt.
The specific embodiment
Balance suspension assembly as shown in Figure 2, comprise symmetrically arranged equalizer bearing hub 1, symmetrically arranged balance shaft support 2, be connected with connection shaft 3 between equalizer bearing hub and balance shaft support, the equalizer bearing hub is supported on connection shaft 3 by two oscillating bearings 7 that arrange in opposite directions, and the outer end of equalizer bearing hub is provided with over cap 6; The shaft part of connection shaft 3 is provided with the outside thread axle journal, is connected with fluted nut 8 on the outside thread axle journal, to equalizer bearing hub 1 axial restraint; Described over cap 6 is the blanked parts that adopt Steel Sheet.
As shown in Figure 2, the explanation of cross-notching nut 8: be to have axial groove on nut body, then at the two ends of axial groove, be provided with boss, be connected with lock bolt 9 on boss, the opening of axial groove dwindles, and nut body is pressed on the outside thread axle journal of connection shaft 3, realizes locking.
