Description

【0001】
【発明の属する技術分野】
本発明は、車体にエンジンやトランスミッション等の駆動装置を支持するための装置、とくに、駆動装置の搭載を容易化できる装置に関する。
【0002】
【従来の技術】
従来の車両においては、図3〜図5に例示されているように、エンジン1とトランスミッション2とが一体的に結合された駆動装置3は、それぞれ車両前後方向に延びる左右のサイドレール4に対して、前部がサポート5を含むフロントマウント6により支持されていると共に、後端面が左右のサイドレール4を連結するクロスメンバ7を介してリヤマウント8により支持され、ほぼ水平状態で搭載されている。
【0003】
リヤマウント8は、それぞれ断面略ハット状で開口側を上方に向けてクロスメンバ7の下面へ固着された一対の支持部材10と、各支持部材10の底部にそれぞれ載置されたゴム材11と、各ゴム材11上にそれぞれ一端が固着され他端が垂下した吊り板12とを有し、吊り板12の下部がボルト13によって駆動装置3の後端面に固着されることにより、駆動装置3の後端部がクロスメンバ7から吊り下げられている。
【0004】
この場合、上方から車体に駆動装置3を搭載するときには、駆動装置3の後端部をクロスメンバ7の下方へもぐり込ませる必要があるため、クレーン等でほぼ水平状態に吊り下げられた駆動装置3全体を図6のように一旦車両後方側へ大きく傾斜させて、駆動装置3の後端部を吊り板12の下部へ仮止めし、その後、駆動装置3全体を水平方向へ回動させて、駆動装置3の後部をリヤマウント8によりクロスメンバ7から吊り下げるようにすると共に、駆動装置3の前部を左右のフロントマウント6に固着しなければならなかった。
【0005】
すなわち、駆動装置3の搭載に際しては、重量の大きい駆動装置3をクレーン等で吊り下げながら車両後方側へ大きく傾斜させて吊り板12の下部へ仮止めしたり、元のほぼ水平状態へ回動させたりする操作が必要とされるため、その作業性が悪いという問題があった。
【0006】
【発明が解決しようとする課題】
本発明は、車体へ駆動装置を容易に搭載できるようにしようとするものである。
【0007】
【課題を解決するための手段】
このため、本発明にかかる駆動装置の支持装置は、それぞれ車両前後方向に延びる左右のサイドレールと、上記各サイドレールにそれぞれ一端が固着されて車幅方向内側へ延びそれぞれの他端が相互に対向したブラケットと、車幅方向における両端部がそれぞれ上記各ブラケットの他端に連結され前部が上記サイドレールに支持された駆動装置の後部を下方に支持するセンタ部とを有し、上記ブラケットにおける上記他端及び上記センタ部における上記端部がそれぞれ断面略ハット状であって、上記端部が上方から上記他端に重ね合わされることにより上記端部及び上記他端における車両前後方向の位置決めがなされている。
【0008】
従って、左右のサイドレールにそれぞれブラケットの一端を固着して、それぞれ車幅方向内側へ延びた各ブラケットの他端が相互に対向しているので、駆動装置の後部から上方へ延びるようにその後部へセンタ部を予め固着しておけば、クレーン等により駆動装置をほぼ水平状態に吊り下げたまま上方から降下させて、センタ部の車幅方向における両端部をそれぞれ各ブラケットの上記他端に連結することにより、左右のサイドレールを両ブラケットとセンタ部とで車幅方向に連結できると共に、駆動装置の後部をセンタ部の下方で支持できて、駆動装置をほぼ水平状態のまま車体に搭載させることができ、しかも、ブラケットにおける他端及びセンタ部における端部がそれぞれ断面略ハット状であって、上記端部が上方から上記他端に重ね合わされることにより上記端部及び上記他端における車両前後方向の位置決めがなされるため、センタ部の車幅方向における両端部をそれぞれ各ブラケットの上記他端に連結する際、両者間の車両前後方向位置決めがきわめて簡単となる。
【0009】
以下、本発明の実施形態例について、前記従来装置との同等部分にはそれぞれ同一符号を付けて説明する。
図1及び図2において、エンジン1とトランスミッション2とが一体的に結合された車両の駆動装置3は、それぞれ車両前後方向に延びる左右の断面略コ字状サイドレール4に対して、前部がフロントマウント6により支持されていると共に、後端面が左右のサイドレール4を連結するクロスメンバ20を介してリヤマウント21により支持され、ほぼ水平状態で車体に搭載されている。
【0010】
クロスメンバ20は、ブラケット22、22とセンタ部23とから構成されていて、各ブラケット22はそれぞれ上下の断面略ハット状部材24、25が開口側を上下に向かい合わせにボルト止めされて形成されており、各ブラケット22の一端がそれぞれ左右のサイドレール4に固着されて車幅方向内側へ延びている一方、センタ部23は断面略ハット状で開口側が下方に向けられ、車幅方向における両端部がそれぞれ各ブラケット22の上方部材24における車幅方向内側の端部に上方から係合させられて、ブラケット22の他端にボルト止めされている。
【0011】
リヤマウント21は、車幅方向に間隔をおいてそれぞれ上端がセンタ部23の下面に固着された吊り板26と、吊り板26により両端が支持された軸27と、軸27が中心に配置されて軸27との環状空間にゴム材が充填されたケーシング28と、ケーシング28に一体的に形成されて下端部が駆動装置3の後端面にボルト止めされたブラケット29とから構成され、両ブラケット22における上記他端間の間隔よりも車幅方向に小さく形成されている。
【0012】
すなわち、駆動装置3の後部はリヤマウント21を介してクロスメンバ20により支持されているが、左右のサイドレール4が通常のように断面略コ字状であっても、左右のサイドレール4を連結するクロスメンバ20が両ブラケット22、22とセンタ部23とに3分割されているので、各ブラケット22の一端をそれぞれ左右のサイドレール4に固着しておけば、リヤマウント21を介してセンタ部23に後部が連結された駆動装置3は、図2に2点鎖線で示すように、クレーン等によりほぼ水平に吊り下げられた状態で上方から降下させて、前部をフロントマウント6上に載置させると共に、センタ部23の両端部をそれぞれ各フランジ22における上方部材24の端部に上方から係合させて、センタ部23の両端部と各フランジ22の上記他端とをそれぞれボルト止めすることにより、駆動装置3をほぼ水平状態のまま、駆動装置3の後部をセンタ部23の下方で車体へ支持させることができる。
【0013】
この場合、各ブラケット22の上記他端に対するセンタ部23両端部の係合は、両者がいずれも比較的大きい構造物であるため、それらを組み合わせるための目標が大きく、しかも、相互に係合する各ブラケット22の上方部材24とセンタ部23とがいずれも同じ断面略ハット状であると共に、図1に示されているように、センタ部23の両端部がそれぞれ各上方部材24の端部における上方凸部と重ね合わされるように両者を係合させているので、車両前後方向の位置決めがきわめて簡単となる。
【0014】
従って、車体に対して駆動装置3を搭載させる際、上記従来装置のように重量物である駆動装置3をクレーン等で吊り下げながら車両後方側へ大きく傾斜させたり、元のほぼ水平状態へ回動させたりする操作は全く不要となって、駆動装置3の搭載作業が非常に容易となるので、迅速、かつ、安全に搭載作業を遂行できる大きな長所がある。
【0015】
【発明の効果】
本発明にかかる駆動装置の支持装置においては、左右のサイドレールにそれぞれブラケットの一端を固着して、それぞれ車幅方向内側へ延びた各ブラケットの他端が相互に対向しているため、駆動装置の後部から上方へ延びるようにその後部へセンタ部を予め固着しておけば、クレーン等により駆動装置をほぼ水平状態に吊り下げたまま上方から降下させて、センタ部の車幅方向における両端部をそれぞれ各ブラケットの上記他端に連結することにより、駆動装置の後部をセンタ部の下方で支持できて、駆動装置をほぼ水平状態のまま車体に搭載させることができ、しかも、センタ部の車幅方向における両端部をそれぞれ各ブラケットの上記他端に連結する際、両者間の車両前後方向位置決めがきわめて簡単となるので、その搭載作業がきわめて容易となる。

BACKGROUND OF THE INVENTION
The present invention relates to a device for supporting a drive device such as an engine or transmission on a vehicle body, and more particularly to a device that can facilitate the mounting of the drive device.
[0002]
[Prior art]
In the conventional vehicle, as illustrated in FIGS. 3 to 5, the driving device 3 in which the engine 1 and the transmission 2 are integrally coupled is provided with respect to the left and right side rails 4 extending in the vehicle front-rear direction. The front part is supported by a front mount 6 including a support 5, and the rear end surface is supported by a rear mount 8 via a cross member 7 connecting the left and right side rails 4 and mounted in a substantially horizontal state. Yes.
[0003]
The rear mount 8 includes a pair of support members 10 each having a substantially hat-shaped cross section and fixed to the lower surface of the cross member 7 with the opening side facing upward, and a rubber material 11 placed on the bottom of each support member 10. Each of the rubber members 11 has a suspension plate 12 having one end fixed and the other end suspended, and the lower portion of the suspension plate 12 is fixed to the rear end surface of the drive device 3 by a bolt 13. The rear end portion is suspended from the cross member 7.
[0004]
In this case, when the drive device 3 is mounted on the vehicle body from above, the rear end portion of the drive device 3 needs to be inserted below the cross member 7, so that the drive device is suspended in a substantially horizontal state by a crane or the like. As shown in FIG. 6, the whole 3 is once inclined greatly toward the vehicle rear side, the rear end portion of the driving device 3 is temporarily fixed to the lower part of the suspension plate 12, and then the entire driving device 3 is rotated in the horizontal direction. The rear portion of the driving device 3 was suspended from the cross member 7 by the rear mount 8 and the front portion of the driving device 3 had to be fixed to the left and right front mounts 6.
[0005]
That is, when the drive device 3 is mounted, the heavy drive device 3 is suspended by a crane or the like and is largely inclined to the rear side of the vehicle and temporarily fixed to the lower portion of the suspension plate 12 or rotated to the original substantially horizontal state. There is a problem that the workability is not good because an operation to perform the operation is required.
[0006]
[Problems to be solved by the invention]
The present invention is intended to enable a drive device to be easily mounted on a vehicle body.
[0007]
[Means for Solving the Problems]
For this reason, the drive device support device according to the present invention includes a left and right side rail extending in the vehicle longitudinal direction, and one end fixed to each side rail and extending inward in the vehicle width direction. includes a opposed brackets, and a center portion of both end portions in the vehicle width direction is the front are respectively connected to the other end of each bracket supporting the rear part of the driving device which is supported on the side rails downwards, said bracket The other end and the end portion of the center portion are substantially hat-shaped in cross section, and the end portion is overlapped with the other end from above, thereby positioning the end portion and the other end in the vehicle longitudinal direction. It is gunna.
[0008]
Therefore, one end of each bracket is fixed to each of the left and right side rails, and the other ends of the brackets extending inward in the vehicle width direction face each other, so that the rear part extends upward from the rear part of the drive device. If the center is fixed in advance, the drive unit is lowered from above with a crane or the like suspended from the upper side, and both ends of the center in the vehicle width direction are connected to the other end of each bracket. By doing so, the left and right side rails can be connected in the vehicle width direction by both brackets and the center portion, and the rear portion of the drive device can be supported below the center portion, so that the drive device is mounted on the vehicle body in a substantially horizontal state. it can, moreover, be ends respectively a cross section a hat-shaped in the other end and the center portion of the bracket, superimposed on the other end the end from above Since the vehicle longitudinal direction of the positioning of the end portion and the other end is made by being I, when connecting the both ends in the vehicle width direction of the center portion to the other end of each bracket each vehicle between two front and rear Directional positioning is very simple.
[0009]
In the following, embodiments of the present invention will be described with the same reference numerals assigned to the same parts as those of the conventional apparatus.
1 and 2, the vehicle drive device 3 in which the engine 1 and the transmission 2 are integrally coupled has a front portion with respect to the left and right cross-sectionally substantially U-shaped side rails 4 extending in the vehicle longitudinal direction. While being supported by the front mount 6, the rear end surface is supported by the rear mount 21 via the cross member 20 that connects the left and right side rails 4, and is mounted on the vehicle body in a substantially horizontal state.
[0010]
The cross member 20 is composed of brackets 22 and 22 and a center portion 23. Each bracket 22 is formed by upper and lower cross-sectional substantially hat-shaped members 24 and 25 that are bolted with the opening side facing up and down. and which, while one end of each bracket 22 extends is secured to the left and right side rails 4, respectively in the vehicle width direction inner side, center portion 23 opening side is directed downward in a substantially hat-shaped, both ends in the vehicle width direction The respective parts are engaged with the end portions on the inner side in the vehicle width direction of the upper member 24 of each bracket 22 from above, and are bolted to the other end of the bracket 22.
[0011]
The rear mount 21 has a suspension plate 26 whose upper ends are fixed to the lower surface of the center portion 23 at intervals in the vehicle width direction, a shaft 27 supported at both ends by the suspension plate 26, and the shaft 27. A casing 28 in which an annular space with the shaft 27 is filled with a rubber material, and a bracket 29 formed integrally with the casing 28 and having a lower end bolted to the rear end surface of the drive device 3. 22 is formed smaller in the vehicle width direction than the interval between the other ends.
[0012]
In other words, the rear portion of the drive device 3 is supported by the cross member 20 via the rear mount 21, but the left and right side rails 4 are connected even if the left and right side rails 4 have a substantially U-shaped cross section as usual. Since the cross member 20 to be connected is divided into the brackets 22 and 22 and the center portion 23, if one end of each bracket 22 is fixed to the left and right side rails 4, the center is interposed via the rear mount 21. As shown by a two-dot chain line in FIG. 2, the drive device 3 having the rear portion connected to the portion 23 is lowered from above while being suspended substantially horizontally by a crane or the like, and the front portion is placed on the front mount 6. The both ends of the center portion 23 are engaged with the end portions of the upper member 24 of each flange 22 from above, and both ends of the center portion 23 and each flange 22 are mounted. And the other end by bolted respectively, while the driving device 3 in a substantially horizontal state, the back of the drive unit 3 can be supported to the vehicle body below the center portion 23.
[0013]
In this case, the engagement of the both ends of the center portion 23 with the other end of each bracket 22 is a relatively large structure, and therefore the target for combining them is large, and they are engaged with each other. Each of the upper member 24 and the center portion 23 of each bracket 22 has a substantially hat-like cross section, and as shown in FIG. 1, both end portions of the center portion 23 are respectively at the end portions of the upper members 24. Since both are engaged with each other so as to overlap the upper convex portion, positioning in the vehicle front-rear direction becomes extremely simple.
[0014]
Therefore, when the drive device 3 is mounted on the vehicle body, the heavy drive device 3 is suspended with a crane or the like as in the above-described conventional device, and is largely tilted toward the rear of the vehicle or rotated to the original substantially horizontal state. There is a great advantage that the mounting operation can be carried out quickly and safely because the operation of moving is completely unnecessary and the mounting operation of the driving device 3 becomes very easy.
[0015]
【The invention's effect】
In the support device of the drive device according to the present invention, one end of each bracket is fixed to the left and right side rails, and the other end of each bracket extending inward in the vehicle width direction faces each other. If the center part is fixed in advance to the rear part so as to extend upward from the rear part, the drive unit is lowered from above while being suspended in a substantially horizontal state by a crane or the like, and both end parts in the vehicle width direction of the center part by connecting each said other end of each bracket, the rear part of the drive unit can be supported below the center portion, can be mounted on the body remains substantially horizontal state drive, moreover, the car of the center portion when connecting the both end portions in the width direction, each said other end of each bracket, since the vehicle longitudinal direction positioning therebetween becomes extremely simple, the mounting operation is verge It becomes easy Te.
