Description

この発明は、アルミ合金などで形成されるハウジングに液圧路を開閉する電磁弁やポンプなどの装置構成部品を組み付けて構成される液圧ユニットなどの部品組立体、特に、弁部品などの装置構成部品を、高精度に加工された部品組み付け穴の近くに配置し、ハウジングに対してそのハウジングの一部を塑性変形させて固定する構造の部品組立体に関する。   The present invention relates to a component assembly such as a hydraulic unit constructed by assembling device components such as an electromagnetic valve and a pump for opening and closing a hydraulic path in a housing formed of an aluminum alloy or the like, and in particular, a device such as a valve component. The present invention relates to a component assembly having a structure in which a component is disposed near a component assembly hole machined with high precision and a part of the housing is plastically deformed and fixed to a housing.

車両のブレーキ装置に採用されるブレーキ液圧制御用の液圧ユニットは、少なくとも、動力駆動のポンプと、液圧制御用の電磁弁をハウジングに組み込んで構成されるものが主流をなしている。この液圧ユニットは、車両の各車輪に設けたホイールシリンダの液圧を必要に応じて前記電磁弁で制御する。また、ハウジングの一面に装着したモータで前記ポンプを駆動して液圧を発生させ、その液圧を減圧後の再加圧用として、あるいは自動ブレーキ制御時の制動液圧としてホイールシリンダに供給する。   The main component of a hydraulic unit for controlling brake hydraulic pressure employed in a vehicle brake device is at least a power-driven pump and an electromagnetic valve for controlling hydraulic pressure incorporated in a housing. The hydraulic unit controls the hydraulic pressure of a wheel cylinder provided on each wheel of the vehicle with the electromagnetic valve as necessary. Further, the pump is driven by a motor mounted on one surface of the housing to generate a hydraulic pressure, and the hydraulic pressure is supplied to the wheel cylinder for repressurization after depressurization or as a braking hydraulic pressure at the time of automatic brake control.

この種の装置において電磁弁などの部品を液圧ユニットのハウジングに固定する方法として、ハウジングを塑性変形させて部品を固定する、いわゆるかしめ固定法がある。その具体例として、例えば下記特許文献１は、液圧制御ユニットのハウジング(弁収容ボディと称している)にそのハウジングを変形させて電磁弁の弁ハウジングを固定している。
特許第３２８１３８５号公報 As a method for fixing a component such as an electromagnetic valve to the housing of the hydraulic unit in this type of apparatus, there is a so-called caulking fixing method in which the housing is plastically deformed to fix the component. As a specific example thereof, for example, in Patent Document 1 described below, a valve housing of a solenoid valve is fixed by deforming the housing of a hydraulic pressure control unit (referred to as a valve housing body).
Japanese Patent No. 3281385

上述したブレーキ液圧制御用の液圧ユニットは、小型化が目覚しく進展しているが、さらなる小型化が強く望まれている。また、一方で、軽量化のために、ハウジングの素材としてアルミ合金を採用することが一般化している。   The above-described hydraulic pressure control unit for controlling brake hydraulic pressure has been remarkably reduced in size, but further reduction in size is strongly desired. On the other hand, in order to reduce the weight, it is common to use an aluminum alloy as a material for the housing.

上記の小型化の要求に応えるには、部品の高密度配置が不可欠であり、その高密度配置のために、ハウジングにかしめ固定される部品の近くに他部品用の部品組み付け穴を設けざるを得ないケースが生じてくる。   In order to meet the above demands for miniaturization, high-density arrangement of components is indispensable. For this high-density arrangement, component assembly holes for other components must be provided near the components that are caulked and fixed to the housing. There are cases where you cannot get it.

ところが、ハウジングをかしめ変形させると、そのときにハウジングに加えられた力がかしめ固定部に近接した他部品用の部品組み付け穴部に伝播してその部品組み付け穴が変形する。鉄系部品に比べて強度の低いアルミ合金製のハウジングではその現象が特に顕著である。この変形が大きいと、変形した部品組み付け穴に対する部品の組み付けに支障がでることが考えられる。また、他部品用部品組み付け穴に摺動部品（例えば、ピストンポンプのピストンなど）が組み付けられる場合には、穴に挿入した部品の円滑な摺動の阻害要因となる懸念が生じる。   However, when the housing is caulked and deformed, the force applied to the housing at that time propagates to the component assembling hole for other components near the caulking fixing portion, and the component assembling hole is deformed. This phenomenon is particularly remarkable in a housing made of an aluminum alloy, which has a lower strength than iron-based parts. If this deformation is large, it can be considered that there is a problem in assembling the parts into the deformed part assembling holes. Further, when a sliding component (for example, a piston of a piston pump) is assembled in the component assembly hole for other components, there is a concern that it may be an obstacle to smooth sliding of the component inserted into the hole.

現状技術では、その不具合を回避するために、ハウジングのかしめ固定部から他部品用部品組み付け穴までの距離(その間のハウジング肉厚）を十分に確保しており、このためにハウジングの体格が増し、このことが、製品のさらなる小型化を図る上でのネックになっている。   In the current technology, in order to avoid the problem, the distance from the caulking fixing part of the housing to the parts assembly hole for other parts (the thickness of the housing between them) is sufficiently secured, which increases the size of the housing. This is a bottleneck in further downsizing the product.

この発明は、電磁弁やポンプなどをハウジングに組み付けて構成される液圧ユニットなどの部品組立体のさらなる小型化を図るために、ハウジングをかしめ変形させるときの力による他部品用部品組み付け穴の変形を、かしめ固定部から他部品用部品組み付け穴までのハウジング肉厚を増やさずに抑制できるようにすることを課題としている。   In order to further reduce the size of a component assembly such as a hydraulic unit constructed by assembling a solenoid valve, a pump, or the like to a housing, the present invention can provide a component assembly hole for other components by force when caulking and deforming the housing. It is an object of the present invention to make it possible to suppress deformation without increasing the thickness of the housing from the caulking fixing part to the part assembly hole for other parts.

上記の課題を解決するため、この発明においては、ハウジングに第１の部品組み付け穴が設けられ、その第１の部品組み付け穴に挿入された装置構成部品の前記ハウジングに対する固定が同ハウジングにおいて前記装置構成部品を着座させる座面を変形させてかしめ固定部を形成するかしめ固定によってなされ、さらに、前記かしめ固定部の近傍に設けられた第２の部品組み付け穴に他部品を組み付けて構成される部品組立体の前記ハウジングに、前記座面をかしめ変形させるときにハウジングに加わった力で変形して前記第２の部品組み付け穴における前記他部品組み付け部分へ伝播される力を減衰させる変形犠牲部を設けた。   In order to solve the above-described problems, in the present invention, a first component assembly hole is provided in a housing, and a device component inserted into the first component assembly hole is fixed to the housing in the housing. A component that is formed by caulking and fixing a seating surface on which a component is seated to form a caulking fixing portion, and is configured by assembling another component into a second component assembling hole provided in the vicinity of the caulking fixing portion. A deformation sacrificial portion that is deformed by the force applied to the housing when the seating surface is caulked and deformed in the housing of the assembly to attenuate the force transmitted to the other component assembling portion in the second component assembling hole. Provided.

前記変形犠牲部は、以下に記すものが具体的な態様として考えられる。
（１）第１の部品組み付け穴の内周面に、前記座面を前記穴の径方向の内側に突出させるリセス加工の溝を設けてその溝と前記座面との間のハウジング肉部を変形犠牲部となしたもの。
（２）前記かしめ固定部と前記第２の部品組み付け穴との間において前記ハウジングの内部に空孔を設け、その空孔を前記変形犠牲部となしたもの。 The deformation sacrificial part is considered as a specific embodiment described below.
(1) A recess groove is provided on the inner peripheral surface of the first part assembly hole so that the seat surface protrudes inward in the radial direction of the hole, and a housing meat portion between the groove and the seat surface is provided. What became the deformation sacrificial part.
(2) A hole is provided in the housing between the caulking fixing portion and the second component assembly hole, and the hole is used as the deformation sacrifice portion.

前記（２）の空孔による変形犠牲部は、前記かしめ固定部に近接した位置で前記ハウジングに孔を設けてその孔で構成すると加工が容易である。この場合の孔は、第１の部品組み付け穴の軸心と平行な軸線を有する孔、第１の部品組み付け穴の軸心に対して垂直な軸線を有する孔の双方が考えられる。このうち、前者の第１の部品組み付け穴の軸心と平行な軸線を有する孔は、後者の孔に比べると設置規制が少ないと考えられる。   The deformation sacrificial part due to the holes of (2) is easy to process if a hole is provided in the housing at a position close to the caulking fixing part. The hole in this case may be both a hole having an axis parallel to the axis of the first component assembly hole and a hole having an axis perpendicular to the axis of the first component assembly hole. Among these, the hole having an axis parallel to the axis of the former first component assembly hole is considered to have fewer installation restrictions than the latter hole.

なお、この発明を適用する部品組立体は、第１の部品組み付け穴に液圧路を開閉する電磁弁が組み付けられ、第２の部品組み付け穴にモータによって駆動されるピストンポンプが組み付けられ、ブレーキ液圧制御用の液圧ユニットとして構成されたものが考えられる。ただし、ブレーキ以外の機器用の部品組立体に適用しても発明の効果が期待できる。変形犠牲部を構成する孔は、液圧通路を兼用することができる。   In the component assembly to which the present invention is applied, a solenoid valve that opens and closes the hydraulic path is assembled in the first component assembly hole, and a piston pump driven by a motor is assembled in the second component assembly hole. What was comprised as a hydraulic-pressure unit for hydraulic-pressure control can be considered. However, the effects of the invention can be expected even when applied to parts assemblies for equipment other than brakes. The hole constituting the deformation sacrificial part can also serve as a hydraulic pressure passage.

液圧ユニットのほかに、空気圧制御用のユニットなども考えられる。また、第１の部品組み付け穴に組み付ける装置構成部品は、電磁弁のほかに、液流に方向性を与えるチェック弁や、第１の部品組み付け穴の入口を塞ぐ封止栓などもあり、これらの部品もハウジングにかしめ固定することがある。従って、「ハウジングにかしめ固定する部品がある」、「その部品の近くに摺動部品などを挿入する第２の部品組み付け穴がある」の２つの条件が成立する部品組立体が、この発明の適用対象となる。   In addition to the hydraulic unit, an air pressure control unit is also conceivable. In addition to the solenoid valve, the device components that are assembled in the first part assembly hole include a check valve that gives direction to the liquid flow and a sealing plug that closes the inlet of the first part assembly hole. These parts may also be caulked and fixed to the housing. Therefore, a component assembly that satisfies the two conditions of “there is a component that is caulked and fixed to the housing” and “the second component assembly hole for inserting a sliding component near the component” is satisfied. Applicable.

この発明の部品組立体は、ハウジングに変形犠牲部を設けており、ハウジングをかしめ変形させるときに変形犠牲部が犠牲になって変形する。これにより、ハウジングに加わる力が吸収され、ハウジングの座面から第２の部品組み付け穴に伝播する力が小さくなって、近傍でハウジングをかしめることに起因した第２の部品組み付け穴の変形が抑制されるようになる。   In the component assembly according to the present invention, the housing is provided with the deformation sacrificial portion, and when the housing is caulked and deformed, the deformation sacrificial portion is sacrificed and deformed. As a result, the force applied to the housing is absorbed, the force propagated from the seating surface of the housing to the second component assembly hole is reduced, and the deformation of the second component assembly hole caused by caulking the housing in the vicinity is reduced. It will be suppressed.

なお、第１の部品組み付け穴の内周面に、前記座面を前記穴の径方向の内側に突出させるリセス加工の溝を設けてその溝と前記座面との間のハウジング肉部を変形犠牲部となすものは、前記溝を環状溝にするとその溝の加工がし易いが、その溝は第２の部品組み付け穴側に偏った位置で第１の部品組み付け穴の内周面の一部を凹ませるもの(非環状溝)であってもよい。   A recess groove is provided on the inner peripheral surface of the first part assembly hole so that the seat surface protrudes inward in the radial direction of the hole, and the housing meat portion between the groove and the seat surface is deformed. For the sacrificial part, if the groove is an annular groove, the groove is easy to process. However, the groove is located on the inner peripheral surface of the first component assembly hole at a position biased toward the second component assembly hole. It may be a concave part (non-annular groove).

前記変形犠牲部を空孔で形成するものは、その空孔が力の伝播経路の途中に配置されていると効果が高いので、空孔をハウジングの座面と第２の部品組み付け穴との間に設ける。   In the case where the deformation sacrificial part is formed by a hole, the effect is high when the hole is arranged in the middle of the propagation path of the force. Therefore, the hole is formed between the seating surface of the housing and the second part assembly hole. Provide between.

なお、リセス加工の溝を設けて作り出される変形犠牲部と空孔によって作り出される変形犠牲部は、効果の面では大きな優位差がないので、加工の便宜を考えて適当と思われるものを選択すればよい。変形犠牲部をハウジングに孔をあけて形成する場合の孔の向きも、加工面で有利な方を選択すればよい。孔の向きが違っても力の伝達防止効果はほとんど差のないものになる。   Note that the deformation sacrificial part created by providing a recess groove and the deformation sacrificial part created by the hole are not significantly different in terms of effect, so select the one that seems appropriate for the convenience of processing. That's fine. What is necessary is just to select the direction of a hole in the case of forming a deformation | transformation sacrificial part by making a hole in a housing, and a process surface is advantageous. Even if the direction of the hole is different, the effect of preventing force transmission is almost the same.

変形犠牲部をハウジングにあけた孔で構成し、その孔を液圧通路として兼用するものは、ハウジングの内部スペースの有効活用が図れ、液圧ユニットなどの小型化に関してより有利になる。なお、孔によって形成される変形犠牲部は、犠牲変形によって孔が変形するが、液体通路は僅かに変形するぐらいでは通路としての機能が損われることがない。   When the deformation sacrificial part is formed by a hole formed in the housing and the hole is also used as a hydraulic pressure passage, the internal space of the housing can be effectively used, which is more advantageous for downsizing the hydraulic pressure unit and the like. Note that the deformation sacrificial portion formed by the hole is deformed by the sacrificial deformation, but the function of the passage is not impaired as long as the liquid passage is slightly deformed.

以下、添付図面の図１〜図７に基づいてこの発明の実施の形態を説明する。図１は、この発明を適用したブレーキ液圧制御用の液圧ユニットの要部を示している。図示の液圧ユニット１は、ハウジング２と、液圧制御用の電磁弁１０と、ピストンポンプ２０を組み合わせて構成されている。   Hereinafter, embodiments of the present invention will be described with reference to FIGS. FIG. 1 shows a main part of a hydraulic unit for brake hydraulic pressure control to which the present invention is applied. The illustrated hydraulic unit 1 is configured by combining a housing 2, an electromagnetic valve 10 for controlling hydraulic pressure, and a piston pump 20.

ハウジング２には、第１の部品組み付け穴３と第２の部品組み付け穴４が設けられ、第１の部品組み付け穴３に電磁弁１０が、第２の部品組み付け穴４にピストンポンプ２０がそれぞれ組み付けられている。   The housing 2 is provided with a first component assembly hole 3 and a second component assembly hole 4. The solenoid valve 10 is provided in the first component assembly hole 3, and the piston pump 20 is provided in the second component assembly hole 4. It is assembled.

電磁弁１０は、弁スリーブ１１と、その弁スリーブの外周に装着される励磁用のコイル（図示せず）と、そのコイルを覆うヨーク（これも図示せず）と、固定鉄心を兼用した弁ハウジング１２と、一体の弁棒１３を有する可動鉄心１４と、弁ハウジング１２の内部に設けられた弁部１５及びチェック弁１６と、弁棒１３に復帰力を加える復帰スプリング１７と、フィルタ１８を組み合わせて構成されている。   The solenoid valve 10 is a valve that combines a valve sleeve 11, an exciting coil (not shown) mounted on the outer periphery of the valve sleeve, a yoke (not shown) covering the coil, and a fixed iron core. A housing 12, a movable iron core 14 having an integral valve rod 13, a valve portion 15 and a check valve 16 provided inside the valve housing 12, a return spring 17 that applies a restoring force to the valve rod 13, and a filter 18 are provided. It is configured in combination.

図示の電磁弁１０は、コイルに通電して磁力を発生させると可動鉄心１４が弁ハウジング１２側に吸引され、弁棒１３で保持した弁体１５ａが弁座１５ｂに接触して弁部１５が閉ざされる。この電磁弁は周知の弁であるので、詳細説明は省く。   In the illustrated electromagnetic valve 10, when a coil is energized to generate a magnetic force, the movable iron core 14 is attracted to the valve housing 12 side, the valve body 15a held by the valve rod 13 contacts the valve seat 15b, and the valve portion 15 is Closed. Since this solenoid valve is a well-known valve, detailed description is omitted.

図２のピストンポンプは、第２の部品組み付け穴４に摺動自在に挿入したピストン２１と、吸入弁２２と吐出弁２３を組み合わせて構成されている。ピストン２１は、モータ（図示せず)の出力軸に取り付けたカム２４(偏心したベアリング）に駆動されて往復運動し、その運動でポンプ室２５にブレーキ液が吸入され、さらに吸入されたブレーキ液が圧縮されて吐出される。このピストンポンプ２０も周知であるので、詳細説明は省く。   The piston pump of FIG. 2 is configured by combining a piston 21 slidably inserted into the second component assembly hole 4, a suction valve 22 and a discharge valve 23. The piston 21 is driven by a cam 24 (eccentric bearing) attached to an output shaft of a motor (not shown) to reciprocate, and the brake fluid is sucked into the pump chamber 25 by the movement, and the brake fluid sucked is further sucked. Is compressed and discharged. Since this piston pump 20 is also well-known, detailed description is omitted.

電磁弁１０のハウジング２に対する組み付けは、弁ハウジング１２を第１の部品組み付け穴３に挿入してハウジング２に固定する方法でなされる。このときの固定は、第１の部品組み付け穴３の入口部の縁に設けられたハウジング２の座面５(図１に一点鎖線で示す部分）を、弁ハウジング１２に設けられた着座部１２ａで加圧して塑性変形させ、塑性変形した部分を弁ハウジング１２の外周の溝などに係止させる方法が採られる。   The solenoid valve 10 is assembled to the housing 2 by a method in which the valve housing 12 is inserted into the first component assembly hole 3 and fixed to the housing 2. At this time, the seating surface 5 of the housing 2 provided at the edge of the inlet portion of the first part assembly hole 3 (the portion indicated by the one-dot chain line in FIG. 1) is seated on the valve housing 12. And pressurizing and plastically deforming, and a method of locking the plastically deformed portion in a groove on the outer periphery of the valve housing 12 is employed.

このとき、座面５に加えられた力が、座面５の近傍に設けられた第２の部品組み付け穴４に向って伝播される。その力の伝播を減少させるために、図１の液圧ユニット１は、ハウジング２に設けられた第１の部品組み付け穴３の内周面に、リセス加工の溝６を設けている。その溝６の設置によって座面５と、その座面５と溝６との間のハウジング肉部７ａがオーバハング状態（穴３の径方向の内側に突出した状態）になる。   At this time, the force applied to the seat surface 5 is propagated toward the second component assembly hole 4 provided in the vicinity of the seat surface 5. In order to reduce the propagation of the force, the hydraulic unit 1 shown in FIG. 1 is provided with a recess groove 6 on the inner peripheral surface of the first component assembly hole 3 provided in the housing 2. Installation of the groove 6 causes the seat surface 5 and the housing flesh 7a between the seat surface 5 and the groove 6 to be in an overhanging state (a state protruding inward in the radial direction of the hole 3).

座面５は、弁ハウジング１２で図１のＡ方向に加圧することによって塑性変形し、変形した部分が第１の部品組み付け穴３の中心側に突出してかしめ固定部８が形成される。このとき、ハウジング肉部７ａの下側が溝６によってえぐられているため、オーバハング状態になったハウジング肉部７ａが変形犠牲部７となって加圧方向前方(図１において下方）に向けて変位するように変形し（これを犠牲変形と称している）、これにより、かしめ固定部８から周辺に拡散する力が吸収されて減衰し、第２の部品組み付け穴４に向けて伝播される力が小さくなって第２の部品組み付け穴４の要求精度を損なうような変形が回避される。   The seat surface 5 is plastically deformed by applying pressure in the direction A of FIG. 1 with the valve housing 12, and the deformed portion protrudes toward the center of the first part assembly hole 3 to form a caulking fixing portion 8. At this time, since the lower side of the housing flesh 7a is removed by the groove 6, the overhanging housing flesh 7a becomes the deformation sacrificial portion 7 and is displaced toward the front in the pressurization direction (downward in FIG. 1). (This is referred to as sacrificial deformation), whereby the force diffused from the caulking fixing portion 8 to the periphery is absorbed and attenuated, and the force propagated toward the second component assembly hole 4 Therefore, deformation that reduces the required accuracy of the second component assembly hole 4 is avoided.

なお、図１の溝６は、加工性のよい環状溝として形成されているが、この溝６を、図３に示すように、第１の部品組み付け穴３の内周面の第２の部品組み付け穴４側に偏った部分のみに設ける構造でも発明の目的は達成される。   The groove 6 in FIG. 1 is formed as an annular groove having good workability. However, as shown in FIG. 3, the groove 6 is a second part on the inner peripheral surface of the first part assembly hole 3. The object of the invention can also be achieved by a structure provided only in a portion biased toward the assembly hole 4 side.

また、図４或いは図５に示すように、かしめ固定部８と第２の部品組み付け穴４との間においてハウジング２の内部に空孔７ｂ、７ｃを設け、その空孔７ｂ、７ｃを変形犠牲部７となしても発明の目的が達成される。   Further, as shown in FIG. 4 or FIG. 5, holes 7b and 7c are provided in the housing 2 between the caulking fixing portion 8 and the second component assembly hole 4, and the holes 7b and 7c are deformed and sacrificed. Even if it becomes the part 7, the object of the invention is achieved.

図４の空孔７ｂは、第１の部品組み付け穴３の軸心と平行な軸線を有する孔として形成されている。また、図５の空孔７ｃは第１の部品組み付け穴３の軸心に対して垂直な軸線を有する孔として形成されている。図４の空孔７ｂは、図５の空孔７ｃに比べると長さが短くて済むため加工規制を受け難く、図５の空孔よりも現実的であるが、犠牲変形については図５の空孔でも優位差の無い効果を期待できる。   The hole 7b in FIG. 4 is formed as a hole having an axis parallel to the axis of the first component assembly hole 3. 5 is formed as a hole having an axis perpendicular to the axis of the first component assembly hole 3. As shown in FIG. The hole 7b in FIG. 4 is shorter in length than the hole 7c in FIG. 5 and is less subject to processing restrictions, and is more realistic than the hole in FIG. Even if there is a hole, an effect with no significant difference can be expected.

なお、図４の空孔７ｂ、図５の空孔７ｃは、どちらも、座面５のかしめによる塑性変形を妨げない範囲でかしめ固定部８にできるだけ近接した位置に配置すると好ましく、そのような配置にすると第２部品組み付け穴４に向って伝播する力の減衰が効果的になされる。   It is preferable that the hole 7b in FIG. 4 and the hole 7c in FIG. 5 are arranged at positions as close as possible to the caulking fixing portion 8 as long as the plastic deformation due to caulking of the seating surface 5 is not hindered. When arranged, the force propagating toward the second part assembly hole 4 is effectively attenuated.

図４の空孔７ｂ、図５の空孔７ｃとも、部品組立体が液圧ユニットである場合には、液圧通路を兼用した孔を利用することができ、ハウジング２の内部スペースの有効活用により液圧ユニットのさらなる小型化に寄与できる。   When both the hole 7b in FIG. 4 and the hole 7c in FIG. 5 are hydraulic units, holes that also serve as a hydraulic passage can be used, and the internal space of the housing 2 can be used effectively. This can contribute to further downsizing of the hydraulic unit.

なお、かしめ固定によって第１の部品組み付け穴３に組み付けられる装置構成部品は、上述した電磁弁１０のほかに、図６に示すチェック弁２６や図７に示す封止栓３２なども考えられる。   In addition to the electromagnetic valve 10 described above, the device components that are assembled into the first component assembly hole 3 by caulking and fixing may be the check valve 26 shown in FIG. 6, the sealing plug 32 shown in FIG.

図６のチェック弁２６は、弁体２７、弁座２８ａを有するシート部品２８、弁体２７に閉弁力を加えるスプリング２９、シート部品２８に固定される弁ホルダ３０及び内部を通過する液体を濾過するフィルタ３１とで構成され、ハウジング２に形成された第１の部品組み付け穴３の入口部にシート部品２８がかしめ固定して取り付けられる。   6 includes a valve body 27, a seat part 28 having a valve seat 28a, a spring 29 that applies a closing force to the valve body 27, a valve holder 30 that is fixed to the seat part 28, and liquid that passes through the interior.
