Description

ブレーキチャンバーブラケットの取付構造およびドライブアクスルBrake chamber bracket mounting structure and drive axle
　本開示は、ブレーキチャンバーブラケットの取付構造およびドライブアクスルに関する。 This disclosure relates to a brake chamber bracket mounting structure and a drive axle.
　例えば、後車軸に対して車両後方の位置にブレーキチャンバーが設けられる。このような位置に設けられたブレーキチャンバーは、路面から比較的に近いため、車両の後方移動により、路面上の突起物がブレーキチャンバーに衝突するときがある。また、車両の走行中に小石がブレーキチャンバーにぶつかり、あるいは、泥がブレーキチャンバーにかかるときがある。これらの原因により、ブレーキチャンバーに損傷を与える。ブレーキチャンバーの損傷を防ぐために、保護カバーが設けられる。 For example, a brake chamber is provided at a position behind the vehicle with respect to the rear axle. Since the brake chamber provided at such a position is relatively close to the road surface, a protrusion on the road surface may collide with the brake chamber due to the rearward movement of the vehicle. In addition, pebbles may hit the brake chamber while the vehicle is running, or mud may enter the brake chamber. These causes damage the brake chamber. A protective cover is provided to prevent damage to the brake chamber.
　後輪二軸の場合に使われる懸架方式の一つとして、例えばトラニオン式サスペンションが用いられる。トラニオン式サスペンションは、車軸の駆動力を確実に路面に伝えるのに適しており、荷重の耐久性に優れており、大型トラックなどに採用される。例えば、トラニオン式サスペンションは、車軸を車体フレームに連結するＶロッドおよびトルクロッド、並びに、車軸の上下動を吸収するリーフスプリングを有する。 For example, a trunnion type suspension is used as one of the suspension systems used in the case of a rear wheel biaxial. The trunnion suspension is suitable for reliably transmitting the axle driving force to the road surface, has excellent load durability, and is used in large trucks. For example, the trunnion suspension has a V rod and a torque rod that connect the axle to the vehicle body frame, and a leaf spring that absorbs the vertical movement of the axle.
　後輪二軸におけるリアアクスルは、車両荷重を分担する役目と駆動力を車軸に伝達する役目を持つドライブアクスルと車両荷重を分担する役目のみを持つデッドアクスルに分けられる。例えば、二軸（前軸および後軸）に、ドライブアクスルが用いられる。また、前軸にドライブアクスルが用いられ、後軸にデッドアクスルが用いられる。 The rear axle on the two rear wheels is divided into a drive axle that has a role of sharing the vehicle load and a drive axle that has a role of transmitting the driving force to the axle, and a dead axle that has only the role of sharing the vehicle load. For example, a drive axle is used for two axes (front axis and rear axis). Also, a drive axle is used for the front axle and a dead axle is used for the rear axle.
　図１は、ドライブアクスル２のアクスルケース３を車両後方から見た図である。図１に示すように、アクスルケース３の長手方向の中央部に膨らみ部３１が設けられる。一対の車体フレーム１，１間は、アクスルケース３の膨らみ部３１の上方空間４になっている。 FIG. 1 is a view of the axle case 3 of the drive axle 2 as seen from the rear of the vehicle. As shown in FIG. 1, a bulging portion 31 is provided at the center portion in the longitudinal direction of the axle case 3. Between the pair of body frames 1, 1 is an upper space 4 of the bulging portion 31 of the axle case 3.
　例えば、特許文献１には、アクスルケース３の膨らみ部３１の上面に、サスペンションブラケット５、サスペンションブラケット５の右側にブレーキチャンバーブラケット６、および、左側にブレーキチャンバーブラケット７をそれぞれ溶接したものが開示されている。 For example, Patent Document 1 discloses a suspension bracket 5, a brake chamber bracket 6 on the right side of the suspension bracket 5, and a brake chamber bracket 7 on the left side, which are welded to the upper surface of the bulging portion 31 of the axle case 3. ing.
　サスペンションブラケット５にはトラニオン式サスペンションのＶロッド（図示せず）の後端部が連結され、Ｖロッドの前端部が一対の車体フレーム１，１側の支持ブラケット１２，１２に連結される。以下、一対の車体フレーム１間であって、アクスルケースの中央部の上方の空間を、部品の取付スペースとして見たとき上方空間４といい、部品の取付作業をする際の作業スペースとして見たとき作業空間４という。なお、一般的に、車体フレーム１の上方には、ベセルやベセルを昇降させる装置などが設けられるため、リアアクスルに関係する部品は設けられない。 The rear end of a V-rod (not shown) of a trunnion type suspension is connected to the suspension bracket 5, and the front end of the V-rod is connected to a pair of support brackets 12, 12 on the vehicle body frame 1, 1 side. Hereinafter, the space between the pair of body frames 1 and above the center portion of the axle case is referred to as an upper space 4 when viewed as a component mounting space, and is viewed as a work space when performing component mounting work. Sometimes called workspace 4. In general, the bezel, the device for raising and lowering the bezel, and the like are provided above the body frame 1, and thus no parts related to the rear axle are provided.
　上方空間４の中央部は、Ｖロッドの後端部をサスペンションブラケット５に連結する際の作業空間４Ａとなる。また、上方空間４の両端部は、Ｖロッドの前端部を支持ブラケット１２，１２に連結する際の作業空間４Ｂとなる。 The central portion of the upper space 4 becomes a work space 4A when the rear end portion of the V rod is connected to the suspension bracket 5. Further, both end portions of the upper space 4 serve as a work space 4B when the front end portion of the V rod is connected to the support brackets 12 and 12.

　近年、製造コストや設計の自由度の観点から、車体フレーム１の形状を車両前後方向に沿ってストレートにする共に、一対の車体フレーム１間の幅を狭くすることが提案されている。これにより、上方空間４が狭くなる。また、より高荷重に耐え得る十分な剛性を確保するために、サスペンションブラケット５を大型にすることが提案され、これにより、上方空間４の中央部がサスペンションブラケット５で大きく占められる。上方空間４の中央部は、Ｖロッドの後端部をサスペンションブラケット５に連結する際の作業空間４Ａでもある。さらに、Ｖロッドの前端部を車体フレーム１側の支持ブラケット１２に連結する際の作業空間４Ｂを上方空間４の両端部に確保する必要もある。その結果、上方空間４の空きスペースがわずかとなり、アクスルケース３の上面に、サスペンションブラケット以外の部品を設けることができないという現状がある。 Recently, from the viewpoint of manufacturing cost and design freedom, it has been proposed to make the shape of the body frame 1 straight along the longitudinal direction of the vehicle and to narrow the width between the pair of body frames 1. Thereby, the upper space 4 becomes narrow. In order to ensure sufficient rigidity to withstand higher loads, it has been proposed to make the suspension bracket 5 large, and thereby the central portion of the upper space 4 is largely occupied by the suspension bracket 5. The central portion of the upper space 4 is also a work space 4 </ b> A when the rear end portion of the V rod is connected to the suspension bracket 5. Further, it is necessary to secure work spaces 4B at both ends of the upper space 4 when the front end portion of the V rod is connected to the support bracket 12 on the vehicle body frame 1 side. As a result, the empty space of the upper space 4 becomes very small, and there is a current situation that parts other than the suspension bracket cannot be provided on the upper surface of the axle case 3.
　保護カバーを設けず、ブレーキチャンバーの損傷を回避するために、ブレーキチャンバーを地上高の高い位置に設けることが好ましい。そのために、例えば、特許文献１に示すように、ブレーキチャンバーブラケットをアクスルケースの上面に設ければよいが、上述する現状により、アクスルケースの上面にブレーキチャンバーブラケットを設けることができないという問題点がある。 In order to avoid damage to the brake chamber without providing a protective cover, it is preferable to provide the brake chamber at a high position above the ground. Therefore, for example, as shown in Patent Document 1, the brake chamber bracket may be provided on the upper surface of the axle case. However, due to the above-described current situation, the brake chamber bracket cannot be provided on the upper surface of the axle case. is there.

　以下、本開示の実施の形態について、図面を参照しながら説明する。
　図２はアクスルケースを車両斜め後方から見た部分斜視図である。 Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
FIG. 2 is a partial perspective view of the axle case as seen from the obliquely rearward side of the vehicle.
　図２に示すように、ドライブアクスル２の本体であるアクスルケース３は、長尺の筒形状をしており、長尺方向の中央部に膨らみ部３１を有し、膨らみ部３１に差動ギアボックス（図示せず）を収納する歯車収容部３２を有し、膨らみ部３１の両側に配置された車輪のドライブシャフトを収納するシャフト収容部３３を有する。歯車収容部３２には、車両後方に開放された開口部（図示せず）が設けられる。膨らみ部３１は、アクスルケース３の上面を上方に円弧状に湾曲させた上面湾曲部３４と、アクスルケース３の下面を下方に円弧状に湾曲させた下面湾曲部３５と、車両後方に略半球形に膨らむドーム部３６と、を有する。ドーム部３６は、歯車収容部３２の開口部を車両後方から覆うように取り付けられた蓋である。 As shown in FIG. 2, the axle case 3 that is the main body of the drive axle 2 has a long cylindrical shape, and has a bulging portion 31 at the center in the longitudinal direction, and the bulging portion 31 has a differential gear. It has a gear housing portion 32 for housing a box (not shown), and a shaft housing portion 33 for housing the wheel drive shafts disposed on both sides of the bulge portion 31. The gear housing portion 32 is provided with an opening (not shown) that is opened to the rear of the vehicle. The bulging portion 31 includes an upper surface curved portion 34 in which the upper surface of the axle case 3 is curved upward in an arc shape, a lower surface curved portion 35 in which the lower surface of the axle case 3 is curved downward in an arc shape, and a substantially hemisphere at the rear of the vehicle. And a dome portion 36 that swells into a shape. The dome portion 36 is a lid attached so as to cover the opening portion of the gear housing portion 32 from the vehicle rear side.
　図３はアクスルケース３を車両後方から見た図である。図３に示すように、アクスルケース３は長尺方向を車軸方向にして配置される。上面湾曲部３４にはサスペンションブラケット５が溶接される。これにより、上方空間４の中央部がサスペンションブラケット５で占められる。仮に、上方空間４の両端部、ここでは、上面湾曲部３４の両側に何らかの部品を取り付けた場合、その部品の大きさに応じて、上方空間４の両端部が狭くなり、Ｖロッドの前端部を支持ブラケット１２に連結する際の作業空間４Ｂも狭くなる。このため、上方空間４の両端部に取り付けられる部品は、大きさの制限を受ける。 FIG. 3 is a view of the axle case 3 as seen from the rear of the vehicle. As shown in FIG. 3, the axle case 3 is arranged with the longitudinal direction as the axle direction. The suspension bracket 5 is welded to the upper curved portion 34. Thereby, the central portion of the upper space 4 is occupied by the suspension bracket 5. If some parts are attached to both ends of the upper space 4, here, both sides of the upper curved portion 34, both ends of the upper space 4 become narrow according to the size of the parts, and the front end of the V rod The working space 4B when connecting to the support bracket 12 is also narrowed. For this reason, the parts attached to both ends of the upper space 4 are limited in size.
　本実施の形態では、ブレーキチャンバー８（図５参照）およびブレーキチャンバーブラケット６，７は、その大きさが制限を超えるため、上方空間４の両端部に設けることができない。つまり、ブレーキチャンバー８等は、上方空間４のいずれにも設けることができない。そこで、ブレーキチャンバー８等を上方空間４から車両後方に離れた位置に設けることが考えられる。ただし、単に、ブレーキチャンバー８等を上方空間４の車両後方の位置に設けると、作業空間４を車両後方から遮るおそれがあるため、ブレーキチャンバー８等の地上高の位置および車軸方向の位置に配慮する必要がある。 In the present embodiment, the brake chamber 8 (see FIG. 5) and the brake chamber brackets 6 and 7 cannot be provided at both ends of the upper space 4 because the size exceeds the limit. That is, the brake chamber 8 or the like cannot be provided in any of the upper spaces 4. Therefore, it is conceivable to provide the brake chamber 8 and the like at a position away from the upper space 4 toward the rear of the vehicle. However, if the brake chamber 8 or the like is simply provided at the position behind the vehicle in the upper space 4, the work space 4 may be blocked from the rear of the vehicle. There is a need to.
　図３に示すように、車軸方向の中心位置４１と上方空間４の中心位置とは一致している。一方、車軸方向の中心位置４１から左方向に長さＬずれた位置に差動ギアボックスが配置される。このため、上面湾曲部３４、下面湾曲部３５、およびドーム部３６は、中心位置４１から左方向に長さＬずれた位置に設けられる。 As shown in FIG. 3, the center position 41 in the axle direction coincides with the center position of the upper space 4. On the other hand, the differential gearbox is disposed at a position shifted by a length L in the left direction from the center position 41 in the axle direction. For this reason, the upper surface curved portion 34, the lower surface curved portion 35, and the dome portion 36 are provided at positions shifted from the center position 41 by the length L in the left direction.
　中心位置４１の右側の位置にブレーキチャンバーブラケット６が設けられる。中心位置４１の左側の位置にブレーキチャンバーブラケット７が設けられる。ブレーキチャンバーブラケット６の貫通穴６０５の中心位置６０５ａ（図４参照）から中心位置４１までの距離は、ブレーキチャンバーブラケット７の貫通穴７０５の中心位置７０５ａ（図４参照）から中心位置４１までの距離と等しい。貫通穴６０５，７０５は、ブレーキチャンバー８のプッシュロッド８１（図４参照）が通る穴である。ドーム部３６が中心位置４１から左方向に長さＬずれた位置に設けられるため、ドーム部３６の頂部３７の位置までの距離は、右側のブレーキチャンバーブラケット６の貫通穴６０５の中心位置６０５ａ（図４参照）からの方が左側のブレーキチャンバーブラケット７の貫通穴７０５の中心位置７０５ａ（図４参照）からの方より長い。ここで、頂部３７とは、ドーム部３６において、開口部を平面で塞いだとき、その平面から最も遠い距離にある位置およびその近傍をいう。 Brake chamber bracket 6 is provided on the right side of center position 41. The brake chamber bracket 7 is provided at a position on the left side of the center position 41. The distance from the center position 605a (see FIG. 4) of the through hole 605 of the brake chamber bracket 6 to the center position 41 is the distance from the center position 705a (see FIG. 4) of the through hole 705 of the brake chamber bracket 7 to the center position 41. Is equal to The through holes 605 and 705 are holes through which the push rod 81 (see FIG. 4) of the brake chamber 8 passes. Since the dome portion 36 is provided at a position shifted by a length L in the left direction from the center position 41, the distance to the position of the top portion 37 of the dome portion 36 is the center position 605a of the through hole 605 of the right brake chamber bracket 6 ( 4) is longer than the direction from the center position 705a (see FIG. 4) of the through hole 705 of the left brake chamber bracket 7. Here, the top portion 37 refers to a position at the farthest distance from the plane and its vicinity in the dome portion 36 when the opening is closed with a plane.
　先ず、右側のブレーキチャンバーブラケット６について図２から図４を参照して説明し、続いて、左側のブレーキチャンバーブラケット７について説明する。 First, the right brake chamber bracket 6 will be described with reference to FIGS. 2 to 4, and then the left brake chamber bracket 7 will be described.
　図３に示すように、ブレーキチャンバーブラケット６は、台座部６０と第１脚部６１と第２脚部６２とを有する。台座部６０、第１脚部６１および第２脚部６２は、例えば、所定厚のスチール製平板にピアス、トリム、曲げなどのプレス加工をすることより一体的に成形される。 As shown in FIG. 3, the brake chamber bracket 6 has a pedestal portion 60, a first leg portion 61, and a second leg portion 62. The pedestal 60, the first leg 61, and the second leg 62 are integrally formed by, for example, pressing a piercing, trimming, bending or the like on a steel flat plate having a predetermined thickness.
　台座部６０は、ブレーキチャンバー８（図５参照）が装着されるもので、第１脚部６１と第２脚部６２とにより、ドーム部３６の頂部３７の位置に対し上側かつ車軸方向の端部側（右側）の位置に設けられる。車軸から貫通穴６０５の中心位置６０５ａまでの高さは、１５０［ｍｍ］から２１０［ｍｍ］であることが好ましく、さらに、１７０［ｍｍ］から１９０［ｍｍ］であることが好ましい。ここで、１５０［ｍｍ］以上としたのは、１５０［ｍｍ］未満では、ブレーキチャンバー８の取付位置が下がってしまい、ブレーキチャンバー８を地上高のより高い位置に配置することに反するためである。２００［ｍｍ］以下としたのは、２００［ｍｍ］を超えると、作業空間４をブレーキチャンバー８が車両後方から遮るようになるためである。なお、貫通穴６０５の中心位置６０５ａをブレーキチャンバー８の「取付位置」という場合がある。 The pedestal portion 60 is mounted with the brake chamber 8 (see FIG. 5). The first leg portion 61 and the second leg portion 62 allow the pedestal portion 60 to be located above the position of the top portion 37 of the dome portion 36 and end in the axle direction. It is provided at the position on the part side (right side). The height from the axle to the center position 605a of the through hole 605 is preferably 150 [mm] to 210 [mm], and more preferably 170 [mm] to 190 [mm]. Here, the reason why it is set to 150 [mm] or more is that if it is less than 150 [mm], the mounting position of the brake chamber 8 is lowered, which is contrary to disposing the brake chamber 8 at a higher position above the ground. . The reason why it is set to 200 [mm] or less is that when it exceeds 200 [mm], the brake chamber 8 blocks the work space 4 from the rear of the vehicle. The central position 605a of the through hole 605 may be referred to as the “attachment position” of the brake chamber 8.
　図４は、アクスルケース３を側方から見た図である。手前側にブレーキチャンバーブラケット７が表わされ、奥側にブレーキチャンバーブラケット６が表されている。以下、ブレーキチャンバーブラケット６を代表して説明する。図４に示すように、台座部６０は、車両後方に向かって斜め上方に傾斜している。台座部６０の水平面に対する傾斜角度θは、０°～２０°が好ましく、さらに、５°～１５°が好ましい。ここで、傾斜角度θを０°以上としたのは、０°未満の傾斜角度θでは、ブレーキチャンバー８の取付位置が下がってしまい、ブレーキチャンバー８を地上高のより高い位置に配置することに反するためである。傾斜角度θを２０°以下としたのは、２０°を超える傾斜角度θでは、ブレーキチャンバー８の取付位置が高くなって、作業空間４をブレーキチャンバー８が車両後方から遮るようになるためである。 FIG. 4 is a view of the axle case 3 viewed from the side. A brake chamber bracket 7 is shown on the front side, and a brake chamber bracket 6 is shown on the back side. Hereinafter, the brake chamber bracket 6 will be described as a representative. As shown in FIG. 4, the pedestal portion 60 is inclined obliquely upward toward the rear of the vehicle. The inclination angle θ of the pedestal 60 with respect to the horizontal plane is preferably 0 ° to 20 °, and more preferably 5 ° to 15 °. Here, the inclination angle θ is set to 0 ° or more. When the inclination angle θ is less than 0 °, the mounting position of the brake chamber 8 is lowered, and the brake chamber 8 is disposed at a higher ground level. This is to go against it. The reason why the inclination angle θ is set to 20 ° or less is that when the inclination angle θ exceeds 20 °, the mounting position of the brake chamber 8 becomes high, and the brake chamber 8 blocks the work space 4 from the rear of the vehicle. .
　台座部６０の傾斜角度θと中心位置６０５ａの高さを組み合わせることで、ブレーキチャンバー８を所望の位置に設けることができる。例えば、傾斜角度θが２０°のとき、中心位置６０５ａの高さを２１０［ｍｍ］とし、傾斜角度θが１０°のとき、中心位置６０５ａの高さを１８０［ｍｍ］とし、傾斜角度θが０°のとき、中心位置６０５ａの高さを１５０［ｍｍ］とすることで、ブレーキチャンバー８を所望の位置に設ける。 The brake chamber 8 can be provided at a desired position by combining the inclination angle θ of the pedestal 60 and the height of the center position 605a. For example, when the inclination angle θ is 20 °, the height of the central position 605a is 210 [mm], and when the inclination angle θ is 10 °, the height of the central position 605a is 180 [mm], and the inclination angle θ is When the angle is 0 °, the brake chamber 8 is provided at a desired position by setting the height of the center position 605a to 150 [mm].
　図４に示すように、ブレーキチャンバー８のプッシュロッド８１がＡ１方向に所定のストロークで作動すると、スラックアジャスタ８２がブレーキカムシャフト８３回りにＡ２方向に回転する。これにより、ブレーキカムシャフト８３の回転力がブレーキ部に伝わり、制動力を発生させる。 As shown in FIG. 4, when the push rod 81 of the brake chamber 8 is operated with a predetermined stroke in the A1 direction, the slack adjuster 82 rotates around the brake cam shaft 83 in the A2 direction. As a result, the rotational force of the brake camshaft 83 is transmitted to the brake portion, and a braking force is generated.
　図２に示すように、台座部６０の外周縁は、前縁６０１、左端縁６０２、右端縁６０３、および、後縁６０４からなる。 As shown in FIG. 2, the outer peripheral edge of the pedestal portion 60 includes a front edge 601, a left end edge 602, a right end edge 603, and a rear edge 604.
　台座部６０の前縁６０１がドーム部３６の外側においてアクスルケース３の後壁３９に溶接される。台座部６０の左端縁６０２側に第１脚部６１が設けられる。台座部６０の右端縁６０３側に第２脚部６２が設けられる。 The front edge 601 of the base part 60 is welded to the rear wall 39 of the axle case 3 outside the dome part 36. A first leg portion 61 is provided on the left end edge 602 side of the pedestal portion 60. A second leg portion 62 is provided on the right end edge 603 side of the pedestal portion 60.
　先ず、第１脚部６１について説明する。第１脚部６１は、ドーム部３６の周縁部３８の位置であって、頂部３７の位置に対し上側かつ車軸方向の端部側の位置（図２に示す台座部６０の左端縁６０２の位置）からドーム部３６に沿って頂部３７の右近傍位置に延ばされた傾斜部６１１を有する。傾斜部６１１がドーム部３６に溶接される。 First, the first leg 61 will be described. The first leg portion 61 is a position of the peripheral portion 38 of the dome portion 36 and is a position on the upper side and the end side in the axle direction with respect to the position of the top portion 37 (the position of the left end edge 602 of the pedestal portion 60 shown in FIG. 2). ) To the right vicinity of the top portion 37 along the dome portion 36. The inclined portion 611 is welded to the dome portion 36.
　図２および図３に示すように、傾斜部６１１を台座部６０の左端縁６０２から斜め下方の位置（頂部３７の右近傍位置）に延ばすことで、溶接長を十分に確保することができる。また、仮に、傾斜部６１１を設けない場合、例えば、台座部６０の左端縁６０２を頂部３７の上方に位置するように、台座部６０の左端縁６０２と右端縁６０３との間の幅を広げると、ブレーキチャンバーブラケット６の重量を増加させてしまう。これに対し、本実施の形態のように、傾斜部６１１を設けることで、ブレーキチャンバーブラケット６を軽量化することができる。 As shown in FIGS. 2 and 3, by extending the inclined portion 611 from the left end edge 602 of the pedestal portion 60 to a position obliquely below (a position near the right of the top portion 37), a sufficient welding length can be secured. If the inclined portion 611 is not provided, for example, the width between the left end edge 602 and the right end edge 603 of the pedestal portion 60 is widened so that the left end edge 602 of the pedestal portion 60 is positioned above the top portion 37. As a result, the weight of the brake chamber bracket 6 is increased. On the other hand, the brake chamber bracket 6 can be reduced in weight by providing the inclined portion 611 as in the present embodiment.
　さらに、第１脚部６１に傾斜部６１１を設けることで、第１脚部６１と、左側のブレーキチャンバーブラケット７の第１脚部７１（後述する）との間に十分な空間ができ、傾斜部６１１をドーム部３６に溶接し、また、第１脚部７１の前縁７１１をドーム部３６に溶接するときに、両者間に十分な空間ができているため、溶接作業をし易くすることができる。 Furthermore, by providing the inclined portion 611 on the first leg portion 61, a sufficient space is formed between the first leg portion 61 and the first leg portion 71 (described later) of the left brake chamber bracket 7. When the part 611 is welded to the dome part 36 and the front edge 711 of the first leg part 71 is welded to the dome part 36, a sufficient space is formed between the two parts, so that the welding operation is facilitated. Can do.
　第１脚部６１は、傾斜部６１１を一辺とする略逆三角形状を有する。略逆三角形状の他の二辺のうちの一辺は、台座部６０の左端縁６０２に沿った辺縁６１２であり、二辺のうちの他の一辺は、傾斜部６１１の下端から辺縁６１２の後端に延ばされた辺縁６１３である。第１脚部６１を略逆三角形状とし、その一辺を傾斜部６１１とすることにより、溶接長を十分に確保することができるとともに、軽量化を図ることができる。 The first leg portion 61 has a substantially inverted triangular shape with the inclined portion 611 as one side. One of the other two sides of the substantially inverted triangular shape is a side edge 612 along the left end edge 602 of the pedestal portion 60, and the other side of the two sides is the side edge 612 from the lower end of the inclined portion 611. It is the edge 613 extended to the rear end. By making the 1st leg part 61 into a substantially inverted triangle shape and making the one side into the inclined part 611, while being able to ensure weld length enough, weight reduction can be achieved.
　次に、第２脚部６２について説明する。第２脚部６２は、台座部６０の右端縁６０３側に設けられる。第２脚部６２の前縁６２１は、ドーム部３６の外側にあってアクスルケース３の後壁３９に溶接される。第２脚部６２の後縁６２２は、前縁６２１から台座部６０の右端縁６０３の後端に沿って設けられ、所定長以上の幅を有するフランジ部６２３である。フランジ部６２３の一部にはブレーキカムシャフト８３（図５参照）を通すための凹部６２４が設けられる。なお、ブレーキチャンバーブラケット６の剛性を上げるために、台座部６０の後縁６０４にフランジ部を設け、フランジ部を介して辺縁６１３とフランジ部６２３とが連続するようにしてもよい。 Next, the second leg 62 will be described. The second leg portion 62 is provided on the right end edge 603 side of the pedestal portion 60. A front edge 621 of the second leg portion 62 is outside the dome portion 36 and is welded to the rear wall 39 of the axle case 3. The rear edge 622 of the second leg portion 62 is a flange portion 623 provided from the front edge 621 along the rear end of the right end edge 603 of the pedestal portion 60 and having a width of a predetermined length or more. A recess 624 for allowing the brake camshaft 83 (see FIG. 5) to pass is provided in a part of the flange portion 623. In order to increase the rigidity of the brake chamber bracket 6, a flange portion may be provided on the rear edge 604 of the pedestal portion 60 so that the edge 613 and the flange portion 623 are continuous via the flange portion.
　次に、ドーム部３６の頂部３７の位置までの距離が短い方の左側のブレーキチャンバーブラケット７について図２から図４を参照して説明する。なお、ブレーキチャンバーブラケット７については、ブレーキチャンバーブラケット６と異なる構成を主に説明し、同じ構成の説明を省略する。 Next, the left brake chamber bracket 7 having a shorter distance to the position of the top 37 of the dome 36 will be described with reference to FIGS. Note that the brake chamber bracket 7 is mainly described in a configuration different from that of the brake chamber bracket 6, and the description of the same configuration is omitted.
　ブレーキチャンバーブラケット７は、台座部７０と第１脚部７１と第２脚部７２とを有する。 The brake chamber bracket 7 has a pedestal portion 70, a first leg portion 71, and a second leg portion 72.
　台座部７０は、ブレーキチャンバー８（図５参照）が装着されるもので、第１脚部７１と第２脚部７２とにより、ドーム部３６の頂部３７の位置に対し上側かつ車軸方向の端部側（左側）の位置に設けられる。 The pedestal portion 70 is mounted with the brake chamber 8 (see FIG. 5). The first leg portion 71 and the second leg portion 72 allow the pedestal portion 70 to be positioned above the position of the top portion 37 of the dome portion 36 and end in the axle direction. It is provided at the position on the part side (left side).
　台座部７０の外周縁は、前縁７０１、左端縁７０２、右端縁７０３、および、後縁７０４からなる。台座部７０の前縁７０１がドーム部３６に溶接される。 The outer peripheral edge of the pedestal portion 70 includes a front edge 701, a left edge 702, a right edge 703, and a rear edge 704. The front edge 701 of the base part 70 is welded to the dome part 36.
　先ず、第１脚部７１について説明する。第１脚部７１は、台座部７０の右端縁７０３側に設けられる。ドーム部３６の周縁部３８の位置であって、頂部３７の位置に対し上側の位置からドーム部３６に沿って頂部３７の左近傍位置に延ばされた前縁７１１を有する。第１脚部７１の前縁７１１がドーム部３６に溶接される。なお、ブレーキチャンバーブラケット７は、頂部３７の位置までの距離が右側のブレーキチャンバーブラケット６より短く、台座部７０の右端縁７０３が頂部３７の左近傍位置の上方に位置しているため、第１脚部７１は、台座部７０の右端縁７０３側からほぼ真下に延ばされ、前述する傾斜部６１１のようなものを設ける必要がない。 First, the first leg 71 will be described. The first leg portion 71 is provided on the right end edge 703 side of the pedestal portion 70. It has a front edge 711 that extends from the position above the position of the top portion 37 to the left vicinity of the top portion 37 along the dome portion 36 at the position of the peripheral portion 38 of the dome portion 36. A front edge 711 of the first leg portion 71 is welded to the dome portion 36. The brake chamber bracket 7 has a distance to the position of the top portion 37 shorter than that of the right brake chamber bracket 6, and the right end edge 703 of the pedestal portion 70 is located above the position near the left of the top portion 37. The leg portion 71 extends almost directly from the right end edge 703 side of the pedestal portion 70, and there is no need to provide the inclined portion 611 described above.
　第１脚部７１は、前縁７１１を一辺とする略逆三角形状を有する。略逆三角形状の他の二辺のうちの一辺は、台座部７０の右端縁７０３に沿った辺縁７１２であり、二辺のうちの他の一辺は、前縁７１１の下端から辺縁７１２の後端に延ばされた辺縁７１３である。 The first leg 71 has a substantially inverted triangular shape with the front edge 711 as one side. One of the other two sides of the substantially inverted triangular shape is a side edge 712 along the right edge 703 of the pedestal portion 70, and the other side of the two sides is a side edge 712 from the lower end of the front edge 711. It is the edge 713 extended to the rear end.
　次に、第２脚部７２について図２から図４を参照して説明する。第２脚部７２は、台座部７０の左端縁７０２側に設けられる。第２脚部７２の構成は、第２脚部６２と基本的に同じである。すなわち、第２脚部７２の前縁７２１は、ドーム部３６の外側にあってアクスルケース３の後壁３９に溶接される。第２脚部７２の後縁７２２は、前縁７２１から台座部７０の左端縁７０２の後端に沿って設けられ、所定長以上の幅を有するフランジ部７２３である。フランジ部７２３の一部にはブレーキカムシャフト８３を通すための凹部７２４が設けられる（図４参照）。なお、ブレーキチャンバーブラケット７の剛性を上げるため、台座部７０の後縁７０４にフランジ部を設け、フランジ部を介して辺縁７１３とフランジ部７２３とが連続するようにしてもよい。 Next, the second leg portion 72 will be described with reference to FIGS. The second leg portion 72 is provided on the left end edge 702 side of the pedestal portion 70. The configuration of the second leg portion 72 is basically the same as that of the second leg portion 62. That is, the front edge 721 of the second leg portion 72 is outside the dome portion 36 and is welded to the rear wall 39 of the axle case 3. The rear edge 722 of the second leg portion 72 is a flange portion 723 provided from the front edge 721 along the rear end of the left end edge 702 of the pedestal portion 70 and having a width of a predetermined length or more. A concave portion 724 for passing the brake cam shaft 83 is provided in a part of the flange portion 723 (see FIG. 4). In order to increase the rigidity of the brake chamber bracket 7, a flange portion may be provided on the rear edge 704 of the pedestal portion 70, and the edge 713 and the flange portion 723 may be continuous via the flange portion.
　次に、アクスルケース３に組み付けられる他の部品について図５を参照して説明する。図５は、ドライブアクスル２を車両後方から見た図である。 Next, other parts assembled to the axle case 3 will be described with reference to FIG. FIG. 5 is a view of the drive axle 2 as seen from the rear of the vehicle.
　図５に示すように、Ｖロッド９の後端部９１がサスペンションブラケット５に連結される。Ｖロッド９の前端部９２が車体フレーム１の支持ブラケット１２に連結される。一対の車体フレーム１の間の上方空間４の両端部には、Ｖロッド９の前端部９２を支持ブラケット１２に車両後方からボルトで連結するための作業空間４Ｂが設けられる。また、上方空間４の中央部には、Ｖロッド９の後端部９１サスペンションブラケット５に車両後方からボルトで連結するための作業空間４Ａが設けられる。作業空間４Ａを車両後方から遮らない位置にブレーキチャンバー８，８がチャンバーブラケット６，７により設けられる。 As shown in FIG. 5, the rear end 91 of the V rod 9 is connected to the suspension bracket 5. The front end 92 of the V rod 9 is connected to the support bracket 12 of the vehicle body frame 1. At both ends of the upper space 4 between the pair of body frames 1, work spaces 4B for connecting the front end 92 of the V rod 9 to the support bracket 12 from the rear of the vehicle with bolts are provided. A work space 4 </ b> A for connecting to the rear end 91 suspension bracket 5 of the V rod 9 with a bolt from the rear of the vehicle is provided at the center of the upper space 4. Brake chambers 8 and 8 are provided by chamber brackets 6 and 7 at positions where the work space 4A is not blocked from the rear of the vehicle.
　この構成によれば、第１脚部６１，７１、第２脚部６２，７２の脚の長さの調整により、また、台座部６０，７０の水平面に対する傾斜角度θの調整などにより、ブレーキチャンバー８，８を地上高のより高い所望の位置に設けることができる。 According to this configuration, the brake chamber is adjusted by adjusting the leg lengths of the first leg portions 61 and 71 and the second leg portions 62 and 72 and by adjusting the inclination angle θ of the pedestal portions 60 and 70 with respect to the horizontal plane. 8, 8 can be provided at a desired position with a higher ground clearance.
　アクスルケース３の端部の上面には、リーフスプリング９３の端部を支えるためのハンガーブラケット９４が溶接される。アクスルケース３の端部の下面には、トルクロッド９５の後端部が連結されるトルクロッドブラケット９６が溶接される。 A hanger bracket 94 for supporting the end of the leaf spring 93 is welded to the upper surface of the end of the axle case 3. A torque rod bracket 96 to which the rear end portion of the torque rod 95 is coupled is welded to the lower surface of the end portion of the axle case 3.
　本実施の形態に係るブレーキチャンバーブラケット６，７の取付構造によれば、第１脚部６１，７１、第２脚部６２，７２により台座部６０，７０を介してブレーキチャンバー８を地上高のより高い位置に、かつ、作業空間４を後方から遮らない位置に設けることができるため、作業空間４を確保して上で、保護カバーを設けずに、ブレーキチャンバー８，８の損傷を回避することができる。 According to the mounting structure of the brake chamber brackets 6 and 7 according to the present embodiment, the brake chamber 8 is raised above the ground via the pedestal portions 60 and 70 by the first leg portions 61 and 71 and the second leg portions 62 and 72. Since the working space 4 can be provided at a higher position and not obstructed from the rear, the work chamber 4 is secured and the protective chamber is not provided, and damage to the brake chambers 8 and 8 is avoided. be able to.
　また、アクスルケース３は上下入力（リーフスプリング（図示略）から鉛直下方に押される力）を受ける。これにより、ドーム部３６が変形し、ドーム部３６とアクスルケース３とを溶接している溶接部に亀裂が発生するおそれがある。本実施の形態では、第１脚部６１，７１をドーム部３６に溶接するとともに、第２脚部６２，７２をドーム部３６の外側においてアクスルケース３に溶接することにより、ブレーキチャンバーブラケット６，７によりドーム部３６とアクスルケース３とがつながれる。これにより、ドーム部３６の剛性を向上させることができ、ドーム部３６の変形を抑え、溶接部に亀裂が発生するのを防止することができる。 Also, the axle case 3 receives vertical input (force pushed vertically downward from a leaf spring (not shown)). Thereby, the dome part 36 deform | transforms and there exists a possibility that the crack may generate | occur | produce in the welding part which welds the dome part 36 and the axle case 3. FIG. In the present embodiment, the first leg portions 61 and 71 are welded to the dome portion 36, and the second leg portions 62 and 72 are welded to the axle case 3 outside the dome portion 36, whereby the brake chamber bracket 6, 7 connects the dome portion 36 and the axle case 3 together. Thereby, the rigidity of the dome part 36 can be improved, the deformation | transformation of the dome part 36 can be suppressed, and it can prevent that a crack generate | occur | produces in a welding part.
　また、図４に示すように、ブレーキチャンバー８のプッシュロッド８１がＡ１方向に作動すると、台座部６０にＲ１方向（面直方向）の反力がかかる。ここで、第１脚部６１において、傾斜部６１１がドーム部３６に溶接され、および、前縁６２１が外壁３９に溶接されているため、並びに、第１脚部６１の辺縁６１３により第１脚部６１の剛性が高くなり、第２脚部６２のフランジ部６２３により第２脚部６２の剛性が高くなるため、反力による台座部６０の変位、変形を抑えることができる。また、図４に示すように、ドーム部３６に溶接された傾斜部６１１の溶接箇所の位置（溶接位置）は、反力が作用するＲ１方向の線からの距離が約５０ｍｍから約１００ｍｍであって、比較的近く、溶接位置にＲ１方向の線に沿ってＲ１方向とは反対のＲ２方向へ引っ張る力が生じる。これによっても、反力による台座部６０の変位、変形を抑えることができる。 Further, as shown in FIG. 4, when the push rod 81 of the brake chamber 8 is operated in the A1 direction, a reaction force in the R1 direction (perpendicular direction) is applied to the pedestal portion 60. Here, in the first leg portion 61, the inclined portion 611 is welded to the dome portion 36, and the front edge 621 is welded to the outer wall 39. Since the rigidity of the leg part 61 is increased and the rigidity of the second leg part 62 is increased by the flange part 623 of the second leg part 62, the displacement and deformation of the pedestal part 60 due to the reaction force can be suppressed. Further, as shown in FIG. 4, the position of the inclined portion 611 welded to the dome portion 36 (welding position) is about 50 mm to about 100 mm from the line in the R1 direction where the reaction force acts. Thus, a force is generated that pulls in the R2 direction opposite to the R1 direction along the line in the R1 direction at the welding position relatively close. Also by this, the displacement and deformation of the pedestal portion 60 due to the reaction force can be suppressed.
　同様に、第１脚部７１において、前縁７１１がドーム部３６に溶接され、および、前縁７２１が外壁３９に溶接されているため、並びに、第１脚部７１の辺縁７１３により第１脚部７１の剛性が高くなり、第２脚部７２のフランジ部７２３により第２脚部７２の剛性が高くなるため、反力による台座部７０の変位、変形を抑えることができる。また、図４に示すように、ドーム部３６に溶接された前縁７１１の溶接箇所の位置（溶接位置）は、反力が作用する方向の線からの距離が約５０ｍｍから約７５ｍｍであって、比較的近く、溶接位置に反力方向の線に沿って反力方向とは反対の方向へ引っ張る力が生じる。これによっても、反力による台座部７０の変位、変形を抑えることができる。 Similarly, in the first leg portion 71, the front edge 711 is welded to the dome portion 36, and the front edge 721 is welded to the outer wall 39, and the first edge portion 713 of the first leg portion 71 is the first. Since the rigidity of the leg part 71 is increased and the rigidity of the second leg part 72 is increased by the flange part 723 of the second leg part 72, the displacement and deformation of the base part 70 due to the reaction force can be suppressed. Further, as shown in FIG. 4, the position (welding position) of the welded portion of the front edge 711 welded to the dome portion 36 is about 50 mm to about 75 mm from the line in the direction in which the reaction force acts. A force that pulls in a direction opposite to the reaction force direction along the line of the reaction force direction is generated relatively close to the welding position. Also by this, the displacement and deformation of the pedestal portion 70 due to the reaction force can be suppressed.
　なお、上記実施の形態では、ブレーキチャンバーブラケット６等を、後輪二軸の後軸に用いられたドライブアクスル２のアクスルケース３に溶接されるものとして説明したが、これに限らない。例えば、ブレーキチャンバーブラケット６等を、後輪二軸の前軸に用いられたドライブアクスル２のアクスルケース３に溶接されるものであってもよい。 In the above-described embodiment, the brake chamber bracket 6 and the like have been described as being welded to the axle case 3 of the drive axle 2 used for the rear axle of the two rear wheels. However, the present invention is not limited to this. For example, the brake chamber bracket 6 or the like may be welded to the axle case 3 of the drive axle 2 used for the front axle of the rear wheel biaxial.
