Description
Technical field
The utility model relates to a kind of adjustment instrument, particularly a kind of hub bearing axial movement space adjusting device.
Background technology
Automobile hub bearing is to bear vehicle weight to reach as the wheel hub transmission provides accurate guide, and bearing not only bears radial load but also bear axial load.Suitably whether hub bearing axial movement space (also claiming pretightning force) is adjusted, and will directly have influence on the combination property of automobile, even injures traffic safety.At present, hub bearing axial movement space method of adjustment is to adopt long torque spanner moment (the different manufacturers technological parameter is different) in accordance with regulations to tighten adjusting nut, process transfer runner hub or the wheel tightened, bearing roller is correctly contacted with inside and outside taper seat, then with about 1/6 ~ 1/4 circle of adjusting nut rollback, rolling brake drum 2 ~ 3 circles.This kind method of adjustment can't be set to hub bearing minimum axial movement space value.Show according to recent statistics information, compare with 0.010mm when the axial movement space value is 0.025mm that the wheel hub life-span can reduce about 50%, and 75% automotive hub is because the life-span of excessive axial float loss 15 ~ 45%.Simultaneously, adjust a small amount of difference of bearing axial movement space, so that axial movement space appears in bearing easily, this is the one of the main reasons that initial failure appears in bearing, and axial movement space is larger, and the bearing premature wear lost efficacy more serious, cause the tire wear aggravation, the life-span of greatly reducing tire.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of wheel hub bearing shaft of more critically adjusting to the hub bearing axial movement space adjusting device of play gap width, in order to improve the performance of wheel hub and automobile.
The technical scheme that solves the problems of the technologies described above is: a kind of hub bearing axial movement space adjusting device, this device comprises that claw, central siphon sleeve, rotation urceolus and central siphon sleeve tighten handle, it is free end that described central siphon sleeve is tightened handle one end, the other end passes the rotation urceolus and is connected with the central siphon sleeve, described central siphon sleeve is installed on the central siphon of hub assembly, and this central siphon sleeve is provided with the scale graticule of being convenient to determine adjusting nut locking packing ring lock groove particular location; Described claw one end is fixed on the rotation urceolus, and the other end is for directly executing the free end that is stated from the hub bearing inner ring.
Further technical scheme of the present utility model is: rotation urceolus handle also is installed on the described rotation urceolus.
Further technical scheme of the present utility model is: described rotation urceolus is equipped with torsion gage also closely being socketed with an outer support by the O RunddichtringO near the central siphon socket end on this outer support.
Again further technical scheme of the present utility model is: described outer support at one end also is fixedly connected with a handle of being convenient to tighten operation.
Because adopt said structure, the hub bearing axial movement space adjusting device of the utility model compared with prior art has following beneficial effect:
1. can critically adjust the wheel hub bearing shaft to the play gap width:
Because the utility model comprises claw, central siphon sleeve, rotation urceolus and sleeve and tightens handle, wherein claw can directly be executed and be stated from hub bearing inner ring, therefore, the utility model changes the adjustment mode of hub bearing axial movement space directly to execute with claw into and is stated from hub bearing inner ring by directly tightening adjusting nut; And because the central siphon sleeve is provided with the scale graticule of being convenient to determine adjusting nut locking packing ring lock groove particular location; So, when with this device the hub bearing axial movement space being adjusted, tightening handle by rotating shaft pipe box cylinder first is fixed in this device on the central siphon of hub assembly, execute to hub bearing inner ring and carry by tightening rotation urceolus handle again, until torsion gage points to particular parameter value, rotate hub assembly 2 ~ 3 circles, the inside and outside taper seat of bearing roller and bearing is correctly contacted; Reverse rotation rotation urceolus handle makes torsion gage return back to particular value, manually tightens adjusting nut, makes the groove on the adjusting nut align scale of the every precession of adjusting nut, the gap width of capable of regulating 0.005mm with scale graticule on this assembly axis pipe box cylinder.Therefore the utility model can be adjusted to minimum with hub bearing axial movement space value, thereby can critically adjust the wheel hub bearing shaft to the play gap width.
2. can prolong the service life of wheel hub, bearing and tire:
Because the utility model can be adjusted to minimum with hub bearing axial movement space value, not only can prolong the service life of wheel hub, also can avoid the hub oil seal earlier period damage, avoid the bearing premature wear inefficacy that axial movement space causes occurring because of bearing, thereby also can reduce the wearing and tearing of tire, prolong the service life of tire.
3. easy to adjust quick, efficient is high:
Because this device in use, it is easy to adjust quick, need not other complicated equipment, and its efficient is higher.
4. can reduce Aftermarket Claims:
Because the utility model can prolong the service life of tire, thereby can effectively reduce Aftermarket Claims.
5. simple in structure, cost is low, is easy to promote the use of.
Below, in conjunction with the accompanying drawings and embodiments the technical characterictic of the hub bearing axial movement space adjusting device of the utility model is further described.
