Abstract
The utility model discloses a kind of bearing life early warning type wheel end assembly, comprise steering swivel, wheel hub, wheel hub cover, interior outer bearing, neck bearing and wheel hub are linked on the axle journal of steering swivel successively, outer bearing is arranged in the outboard-bearing hole of wheel hub, wheel hub cover is with being bolted on wheel hub, the inner end surface of wheel hub cover is near the outer face of steering swivel spindle nose, and the gap A of wheel hub cover inner end surface and steering swivel spindle nose outer face is within the scope of 0.3-0.7mm.The utility model bearing life early warning type wheel end assembly by control wheel hub cap can with the clearance distance of steering swivel spindle nose, when hub bearing occurs play, starts to damage in advance, the wheel hub cover preset will rub with steering stub axle crown end, produce very large sound, thus prompting chaufeur checks bearing, accomplish to change in time in advance, avoid potential safety hazard.
Description
Technical field
The utility model relates to automotive wheels end assembly technical field, and more particularly, it relates to bearing life early warning type wheel end assembly.
Background technology
Existing wheel is held in assembly, tierod assembly connects with steering swivel with track arm, vertical pulling lever arm is connected on steering swivel, neck bearing and wheel hub are linked on steering swivel axle journal successively, outer bearing is arranged in the outboard-bearing hole of wheel hub, and successively lock washer, steering swivel nut are contained on steering swivel spindle nose, with spring cotter locking, then by wheel hub cover with being bolted on wheel hub.The wheel end assembly of existing structure, when hub bearing damages, not obvious sign in advance, by the time chaufeur awares hub bearing when having abnormal, bearing has been in badly damaged state, makes vehicle be in dangerous condition, even has wheel hub to depart from the risk of axletree.
Utility model content
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of bearing life early warning type scientific and reasonable for structure wheel end assembly, start to damage in advance at hub bearing, wheel end assembly can send warning automatically, prompting chaufeur checks bearing, accomplish to change in time in advance, avoid traffic safety hidden danger.
The technical scheme in the invention for solving the technical problem is: bearing life early warning type wheel end assembly, comprise steering swivel, wheel hub, wheel hub cover, interior outer bearing, neck bearing and wheel hub are linked on the axle journal of steering swivel successively, outer bearing is arranged in the outboard-bearing hole of wheel hub, wheel hub cover is with being bolted on wheel hub, the inner end surface of wheel hub cover is near the outer face of steering swivel spindle nose, and the gap A of wheel hub cover inner end surface and steering swivel spindle nose outer face is within the scope of 0.3-0.7mm.
Also comprise tierod assembly, described tierod assembly is connected with steering swivel by track arm.
Vertical pulling lever arm is connected on steering swivel.
The beneficial effects of the utility model are: bearing life early warning type wheel end assembly by control wheel hub cap can with the clearance distance of steering swivel spindle nose, when hub bearing occurs play, starts to damage in advance, the wheel hub cover preset will rub with steering stub axle crown end, produce very large sound, thus prompting chaufeur checks bearing, accomplish to change in time in advance, avoid potential safety hazard.
Accompanying drawing explanation
Fig. 1 is bearing life early warning type of the present utility model wheel end assembly structure schematic diagram.
Detailed description of the invention
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should make broad understanding, such as, can be fixedly connected with.Also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, particular case above-mentioned term can be understood at concrete meaning of the present utility model.
As shown in Figure 1, bearing life early warning type wheel end assembly, comprises the parts such as steering swivel, wheel hub, wheel hub cover, bearing.Wherein, tierod assembly (scheming not shown) is connected with steering swivel 1 by track arm 3, vertical pulling lever arm 4 is connected on steering swivel 1, neck bearing 12 and wheel hub 11 are linked on steering swivel axle journal successively, outer bearing 13 is arranged in the outboard-bearing hole of wheel hub, and wheel hub cover 2 is with being bolted on wheel hub 11.Key is: the inner end surface of wheel hub cover 2 is near the outer face of steering swivel spindle nose 10, and their gap A is within the scope of 0.3-0.7mm.
Because the gap of wheel hub cover inner end surface and steering swivel spindle nose outer face is very little, therefore, when hub bearing appearance damage in advance during end float misalignment, namely it hit wheel hub cover, the steering swivel maintained static and the wheel hub cover of High Rotation Speed produce dry friction, send huge sound, thus remind chaufeur to need check and change bearing, thus avoid occurring serious safety misadventure.
Although illustrate and described embodiment of the present utility model; those of ordinary skill in the art is to be understood that: can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and aim; scope of the present utility model limited by claim and equivalent replacement thereof; in the improvement etc. done without creative work, all should be included within protection domain of the present utility model.
