Description
Technical field
The present invention 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 and for wheel hub transmission provides accurate guide, 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 by directly having 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 (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 by adjusting nut rollback approximately 1/6 ~ 1/4 circle, rolling brake drum 2 ~ 3 encloses.This kind of method of adjustment cannot be set to hub bearing minimum axial movement space value.According to recent statistics information, show, when axial movement space value is 0.025mm, compare with 0.010mm, the wheel hub life-span can reduce about 50%, and 75% automotive hub is due to the life-span of excessive axial float loss 15 ~ 45%.Meanwhile, adjust a small amount of difference of bearing axial movement space, make bearing easily occur axial movement space, this is the one of the main reasons that initial failure appears in bearing, and axial movement space is larger, and bearing premature wear lost efficacy more serious, cause tire wear aggravation, the life-span of greatly reducing tire.
Summary of the invention
The technical problem to be solved in the present invention 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, to improve the performance of wheel hub and automobile.
The technical scheme solving 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 is connected with central siphon sleeve through rotation urceolus, described central siphon sleeve is arranged 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 rotation urceolus, and the other end is for directly executing the free end being loaded on hub bearing inner ring.
Further technical scheme of the present invention is: rotation urceolus handle is also installed on described rotation urceolus.
Further technical scheme of the present invention is: described rotation urceolus, being also closely socketed with an outer support by O RunddichtringO near central siphon socket end, is provided with torsion gage on this outer support.
Further technical scheme more of the present invention is: described outer support is at one end also fixedly connected with a handle of being convenient to tighten operation.
Owing to adopting said structure, the present invention's hub bearing axial movement space adjusting device compared with prior art, has following beneficial effect:
1. can critically adjust wheel hub bearing shaft to play gap width:
Owing to the present invention includes claw, central siphon sleeve, rotation urceolus and sleeve, tighten handle, wherein claw can directly be executed and be loaded in hub bearing inner ring, therefore, the present invention changes the adjustment mode of hub bearing axial movement space with claw into and directly executes and be loaded in hub bearing inner ring by directly tightening adjusting nut; And because 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 hub bearing axial movement space being adjusted with this device, first by rotating shaft pipe box cylinder, tightening handle is fixed on this device on the central siphon of hub assembly, by tightening rotation urceolus handle, to hub bearing inner ring, execute and carry 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, the groove on adjusting nut is alignd, scale of the every precession of adjusting nut, the gap width of capable of regulating 0.005mm with the scale graticule on this assembly axis pipe box cylinder.Therefore the present invention can adjust to minimum by hub bearing axial movement space value, thereby can critically adjust wheel hub bearing shaft to play gap width.
2. can extend the service life of wheel hub, bearing and tire:
Because the present invention can adjust to minimum by hub bearing axial movement space value, not only can extend the service life of wheel hub, also can avoid hub oil seal earlier period damage, avoid losing efficacy because the bearing premature wear that axial movement space causes appears in bearing, thereby also can reduce the wearing and tearing of tire, extend the service life of tire.
3. easy to adjust quick, efficiency is high:
Due to this device in use, it is easy to adjust quick, without other complicated equipment, its efficiency is higher.
4. can reduce Aftermarket Claims:
Because the present invention can extend 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 present invention's hub bearing axial movement space adjusting device is further described.
