Abstract
This utility model provides a kind of simple in construction, and anti-muddy water performance is good, low cost, is suitable for the waterproof construction outside the automobile wheel hub bearing that old structure high-volume is improved.This waterproof construction includes wheel hub, brake disc, mud guard, knuckle and wheel hub bearing, the end sleeve of described knuckle is located on described wheel hub bearing, described mud guard is arranged on the outer ring of described knuckle, it is critical only that the outer ring of described knuckle is additionally provided with mud cover near the side of described wheel hub, described mud cover has the inclined-plane tilted from knuckle outer ring to brake disc inner ring.This utility model is by arranging mud cover in the outer ring of knuckle near the side of wheel hub, block muddy water and be poured into bearing by the gap of knuckle and wheel hub, and mud cover advantageously reduces accumulation and the discharge of muddy water by arranging inclined-plane, thus provides outstanding anti-muddy water performance.
Description
Technical field
This utility model relates to the parts technical field of automobile chassis structures, is specifically related to the waterproof construction outside a kind of automobile wheel hub bearing.
Background technology
What automobile wheel hub bearing structural strength aspect had developed at present is the most ripe.Each parts producer is all in the strick precaution of the invasion being devoted to Bearing outer environment, particularly muddy water.(near drive axle segments) inside corresponding wheel hub bearing, can be coordinated by labyrinth and prevent muddy water from invading；For (close hub end), the most good structural shielding inside wheel hub bearing.It is illustrated in figure 1 the periphery member that tradition coordinates with wheel hub bearing, typically by wheel hub 1, brake disc 2, mud guard 3, knuckle 4, wheel hub bearing 5, five part compositions.Owing near wheel hub 1 end, not having relevant waterproof construction, muddy water is caused can be directly poured into bearing by brake disc 2 and the gap of mud guard 3 and wheel hub 1 and the gap of knuckle 4.Wherein, the arrow in figure is the direction that muddy water flows into.Muddy water is poured into bearing, can cause Bearing inner grease failures, and bearing life reduces.
Summary of the invention
The purpose of this utility model is to propose a kind of simple in construction, and anti-muddy water performance is good, low cost, is suitable for the waterproof construction outside the automobile wheel hub bearing that old structure high-volume is improved.
According to the waterproof construction outside the automobile wheel hub bearing that this utility model provides, including wheel hub, brake disc, mud guard, knuckle and wheel hub bearing, the end sleeve of described knuckle is located on described wheel hub bearing, described mud guard is arranged on the outer ring of described knuckle, it is critical only that the outer ring of described knuckle is additionally provided with mud cover near the side of described wheel hub, described mud cover has the inclined-plane tilted from knuckle outer ring to brake disc inner ring.
Waterproof construction outside automobile wheel hub bearing of the present utility model, by arranging mud cover in the outer ring of knuckle near the side of wheel hub, block muddy water and be poured into bearing by the gap of knuckle and wheel hub, and mud cover advantageously reduces accumulation and the discharge of muddy water by arranging inclined-plane, thus provides outstanding anti-muddy water performance.
Further, described mud cover is interference fit with the outer ring of described knuckle.Such mud cover and the fit structure of knuckle outer ring, have only to be fitted in mud cover knuckle outer ring during installation, be suitable for old structure high-volume and improve.
Specifically, the outer ring of described mud cover and described brake disc inner ring matched in clearance, to facilitate the installation of wheel hub and brake disc.
Accompanying drawing explanation
Fig. 1 is the waterproof construction schematic diagram of existing automobile wheel hub bearing.
Fig. 2 is the waterproof construction schematic diagram outside this utility model automobile wheel hub bearing.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail such as the mutual alignment between the involved shape of each component, structure, each several part and annexation, the effect of each several part and operation principle etc..
Embodiment 1:
Such as Fig. 2, waterproof construction outside automobile wheel hub bearing of the present utility model, including wheel hub 1, brake disc 2, mud guard 3, knuckle 4 and wheel hub bearing 5, the end sleeve of knuckle 4 is located on wheel hub bearing 5, mud guard 3 is arranged on the outer ring of knuckle 4, the outer ring of knuckle 4 is additionally provided with mud cover 6 near the side of wheel hub 1, and mud cover 6 has the inclined-plane 61 tilted from knuckle 4 outer ring to brake disc 2 inner ring.Mud cover 6 is interference fit with the outer ring of knuckle 4.Such mud cover 6 and the fit structure of knuckle 4 outer ring, have only to be fitted in mud cover 6 outer ring of knuckle 4 during installation, be suitable for old structure high-volume and improve.The outer ring of mud cover 6 and brake disc 2 inner ring matched in clearance, to facilitate wheel hub 1 and the installation of brake disc 2.Wherein, the arrow in figure is the direction that muddy water flows into.
Waterproof construction outside automobile wheel hub bearing of the present utility model, by arranging mud cover 6 in the outer ring of knuckle 4 near the side of wheel hub 1, block muddy water and be poured into bearing by the gap of knuckle 4 and wheel hub 1, and mud cover 6 advantageously reduces accumulation and the discharge of muddy water by arranging inclined-plane 61, thus provides outstanding anti-muddy water performance.
