Description
【０００１】[0001]
この考案は、自動車の車軸管の外端部側（車輪側）の車軸を支持する軸受装置 、特に軸受内への泥水やダスト等の侵入を防止することの出来る車軸用軸受装置 に関する。 The present invention relates to a bearing device that supports an axle on the outer end side (wheel side) of an axle pipe of an automobile, and particularly to an axle bearing device that can prevent muddy water, dust, and the like from entering the bearing.
【０００２】[0002]
自動車の半浮動式リヤアクスルでは図３に示すように車軸（回転軸）３の端部 に設けたフランジ３ａに車輪を取付け、該フランジ３ａより内側に軸受装置１を 配置した構造とするものが知られている（実開平３−１０２６１９）。 この軸受装置１は外輪２側を車軸管端部のハウジング６に、内輪４を車軸３に それぞれ嵌合してあるが、泥水等の侵入を防止するためこの軸受装置１にはシ− ルリング５を嵌め込んだものが使用される。またこのような半浮動式リヤアクス ルでは軸受装置１の外輪２を嵌め込むハウジング６の外側にバッキングプレ−ト ７が設けられ、更に該バッキングプレ−ト７には軸受装置１を抑えるように抑え 蓋８が固定されているが、該抑え蓋８は車軸３の段部３ｂとの間に小さな隙間ｄ が形成されるよう取付けられるためダスト侵入の役目をする。 In a semi-floating rear axle of an automobile, as shown in FIG. 3, it is known that a wheel is attached to a flange 3a provided at an end of an axle (rotary shaft) 3 and a bearing device 1 is arranged inside the flange 3a. (Actual Kaihei 3-102619). In this bearing device 1, the outer ring 2 side is fitted in the housing 6 at the end of the axle tube and the inner ring 4 is fitted in the axle 3, respectively. To prevent intrusion of muddy water, etc. The one that is fitted is used. Further, in such a semi-floating rear axle, a backing plate 7 is provided on the outside of the housing 6 into which the outer ring 2 of the bearing device 1 is fitted, and the backing plate 7 is restrained so as to hold down the bearing device 1. Although the lid 8 is fixed, the holding lid 8 is attached so that a small gap d 1 is formed between the restraining lid 8 and the step portion 3b of the axle 3 and thus serves as a dust intrusion.
【０００３】[0003]
上記するように半浮動式リヤアクスルの軸受装置においてシ−ルリング５のみ では防水対策が不完全であり、一方別個に密封装置を組み込むのは構造的にも煩 雑になる傾向がある。この考案はかかる課題に鑑みてなされたものであり、その 目的とするところは比較的構造も簡単で且つ有効な防水機能を有する車軸用軸受 装置を提供することにある。 As described above, in the bearing device for the semi-floating rear axle, the waterproofing measures are not complete only with the seal ring 5, while the separate incorporation of the sealing device tends to be structurally complicated. The present invention has been made in view of such problems, and an object thereof is to provide an axle bearing device having a relatively simple structure and an effective waterproof function.
【０００４】[0004]
即ち、この考案は上記する課題を解決するために、車軸を通した車軸管の外端 部に取付けたハウジングに外輪を嵌合すると共に該車軸には内輪を嵌合しこれら 内・外輪間にシ−ルリングを設け更に前記ハウジング端にはバッキングプレ−ト を取付けると共に該バッキングプレ−トには前記外輪を固定する抑え蓋を取付け て成る車軸用軸受装置において、前記内輪の内周面又は車軸の前記抑え蓋の内側 にスリンガ−を嵌合配置したことを特徴とする。 That is, in order to solve the above-mentioned problems, the present invention fits an outer ring to a housing attached to the outer end of an axle tube that passes through an axle, and fits an inner ring to the axle, and between the inner and outer rings. A bearing device for an axle, comprising a seal ring, a backing plate attached to the housing end, and a retaining cover attached to the backing plate for fixing the outer ring. A slinger is fitted and arranged inside the holding lid.
【０００５】[0005]
車軸用軸受装置を上記手段とすると、スリンガ−９と抑え蓋８とがラビリン ス構造を形成し、また該スリンガ−の遠心作用により泥水やダスト等が侵入しに くくなる。更にスリンガ−９と抑え蓋８との間に水が侵入しても下側のドラムブ レ−キやディスクブレ−キ等に設けた水抜き穴（図示せず）から素早く排出する ことが出来る。 If the bearing device for an axle is used as the above means, the slinger 9 and the restraining lid 8 form a labyrinth structure, and the centrifugal action of the slinger makes it difficult for muddy water, dust and the like to enter. Further, even if water enters between the slinger 9 and the restraining lid 8, it can be quickly drained from a drain hole (not shown) provided in the lower drum brake or disc brake.
【０００６】[0006]
以下、この考案の具体的実施例について図面を参照して説明する。 図１はこの考案の車軸用軸受装置１の軸方向の一部断面図である。この図にお いて説明の都合上、同一構成部品には図３と同一の符号を使用して説明する。 車軸３の端部に形成されたフランジ３ａ内側には段部３ｂが形成され、軸受装 置１は該段部３ｂの内側に配置される。この車軸３に形成された段部３ｂには防 水用のスリンガ−９が圧入嵌合され、軸受装置１はハウジング６と車軸３との間 に配置される。 Hereinafter, a specific embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partial sectional view in the axial direction of an axle bearing device 1 of the present invention. For convenience of explanation, the same reference numerals as those in FIG. 3 are used for the same components in this figure. A step portion 3b is formed inside the flange 3a formed at the end of the axle 3, and the bearing device 1 is arranged inside the step portion 3b. A watertight slinger 9 is press-fitted into the step portion 3b formed on the axle 3, and the bearing device 1 is arranged between the housing 6 and the axle 3.
【０００７】 次に、前記軸受装置１の外輪２を嵌合するハウジング６は懸架装置を介して支 持される車軸管（図示せず）の開口端部に固定されて取付けられるが、該ハウジ ング６端には軸受装置１の外輪２を嵌合し、更に外輪２固定用としてバッキング プレ−ト７を取付ける。こうして軸受装置１を取付けた後、更に該バッキングプ レ−ト７には抑え蓋８が取付けられる。また、車軸３に嵌合された軸受装置１の 内輪４内側にはアキシアル荷重による軸受装置の移動を防止するため内側より固 定用リング１０が嵌め込まれる。前記ハウジング６と該固定用リング１０との間 にもダスト侵入のためのシ−ル１１が配置されている。尚、前記スリンガ−９は 軸受装置の内輪４に仮止めするようにしても良い。Next, the housing 6 into which the outer ring 2 of the bearing device 1 is fitted is fixedly attached to the open end of an axle tube (not shown) supported via a suspension device. The outer ring 2 of the bearing device 1 is fitted to the end of the ring 6, and a backing plate 7 for fixing the outer ring 2 is further attached. After mounting the bearing device 1 in this manner, a holding lid 8 is further mounted on the backing plate 7. Further, a fixing ring 10 is fitted from the inside to the inside of the inner ring 4 of the bearing device 1 fitted to the axle 3 in order to prevent the bearing device from moving due to an axial load. A seal 11 for dust intrusion is also arranged between the housing 6 and the fixing ring 10. The slinger 9 may be temporarily fixed to the inner ring 4 of the bearing device.
【０００８】 この車軸用軸受装置を以上のように構成すれば、スリンガ−９と抑え蓋８とが ラビリンス構造を形成し、また該スリンガ−の遠心作用により泥水やダスト等が 侵入しにくくなる。更にスリンガ−９と抑え蓋８との間に水が侵入しても下側の ドラムブレ−キやディスクブレ−キ等に設けた水抜き穴（図示せず）から素早く 排出することが出来る。When the bearing device for an axle is configured as described above, the slinger 9 and the restraining lid 8 form a labyrinth structure, and the centrifugal action of the slinger makes it difficult for mud and dust to enter. Further, even if water enters between the slinger 9 and the restraining lid 8, it can be quickly drained from a drain hole (not shown) provided in the lower drum brake or disc brake.
【０００９】 図２はこの考案にかかる車軸用軸受装置の変形実施例である。即ち、スリンガ −９は車軸３の段部３ｂに嵌合させるのではなく、軸受装置の内輪４の内周面に 嵌合させても良い（スリンガ−９の向きは逆でも良い）。このようにスリンガ− ９を内輪４の内周面に取付けても同様の作用効果を生じさせることが出来る。FIG. 2 shows a modified embodiment of the bearing device for an axle according to the present invention. That is, the slinger 9 may be fitted to the inner peripheral surface of the inner ring 4 of the bearing device instead of being fitted to the step portion 3b of the axle 3 (the slinger 9 may be reversed). Even if the slinger 9 is attached to the inner peripheral surface of the inner ring 4 in this way, the same effect can be obtained.
【００１０】[0010]
この考案の車軸用軸受装置は以上詳述したような構成としたので、簡単な構造 でしかも効果的に泥水やダストの侵入を防止することが出来る。またこのような 防水構造としても組立てにくくなる等の不都合はなくコスト的にも安価である。 Since the bearing device for an axle of the present invention is configured as described in detail above, it has a simple structure and can effectively prevent the intrusion of muddy water and dust. Even with such a waterproof structure, there is no inconvenience such as difficulty in assembling, and the cost is low.
