Description
本開示は、車両のキャブ後部構造に関する。
The present disclosure relates to a vehicle cab rear structure.
車室の下方を区画するキャブフロアパネルの後端部の下方にキャブの後側の被支持部（キャブリヤ被支持部）を設け、キャブリヤ被支持部を車体側のキャブリヤマウントによって下方から支持する車両のキャブ後部構造が公知である（例えば、特許文献１）。
A vehicle cab rear structure is known in which a cab rear supported part (cabriar supported part) is provided below the rear end of a cab floor panel that defines the lower part of the vehicle compartment, and the cab supported part is supported from below by a cab mount on the vehicle body side (for example, Patent Document 1).
座席（例えば運転席）の後端が車室の後端に近接する車両において、シートバックを後方へ傾動可能とする（リクライニング可能とする）リクライニングスペースを座席の後方に設けるため、キャブを後方へ延長することが考えられる。リクライニングスペースは、荷物を置く空間として利用することもできる。
In a vehicle where the rear end of the seat (for example, the driver's seat) is close to the rear end of the passenger compartment, it is conceivable to extend the cab rearward in order to provide a reclining space behind the seat that allows the seat back to tilt (recline) rearward. The reclining space can also be used as a space for storing luggage.
キャブを後方へ延長する場合、キャブ側及び車体側の設計変更を少なく抑えるためには、キャブリヤ被支持部の位置を変更せず、キャブフロアパネルに片持ち状に支持されてキャブリヤ被支持部よりも車両後方へ延びる延長フロアパネルを設け、キャブリヤ被支持部よりも後方のキャブの後方延長部の床面を延長フロアパネルによって構成することが好ましい。
When extending the cab rearward, in order to minimize design changes on the cab side and the vehicle body side, it is preferable to provide an extended floor panel that is cantilevered on the cab floor panel and extends further to the rear of the vehicle than the cab supported part without changing the position of the cab supported part, and that the floor surface of the rearwardly extended part of the cab behind the cab supported part is composed of the extended floor panel.
しかし、延長フロアパネルがキャブフロアパネルに片持ち状に支持されるので、キャブの後方延長部の支持剛性を確保することが難しい。
However, since the extended floor panel is supported by the cab floor panel in a cantilevered manner, it is difficult to ensure the support rigidity of the rear extension of the cab.
そこで、本開示は、キャブリヤ被支持部よりも車両後方へ延びるキャブの後方延長部の床面がキャブフロアパネルに片持ち状に支持される車両において、キャブの後方延長部の支持剛性を確保することを目的とする。
Therefore, an object of the present disclosure is to ensure the support rigidity of the rearwardly extending portion of the cab in a vehicle in which the floor surface of the rearwardly extending portion of the cab that extends to the rear of the vehicle from the cab supported portion is supported by the cab floor panel in a cantilever manner.
上記目的を達成すべく、本開示の第１の態様は、キャブフロアパネルの後端部の下方に、車体側のキャブリヤマウントによって下方から支持されるキャブリヤ被支持部が設けられ、キャブの後方延長部がキャブリヤ被支持部よりも車両後方へ延びる車両のキャブ後部構造であって、延長フロアパネルと、連結補強部材とを備える。延長フロアパネルは、キャブフロアパネルに片持ち状に支持されてキャブリヤ被支持部よりも車両後方へ延び、キャブの後方延長部の床面を構成する。連結補強部材は、キャブフロアパネルと延長フロアパネルとを連結して補強する。
In order to achieve the above object, a first aspect of the present disclosure is a vehicle cab rear portion structure in which a cab supported portion supported from below by a cab mount on the vehicle body side is provided below the rear end portion of the cab floor panel, and a rear extension portion of the cab extends further to the vehicle rear than the cab supported portion, and includes an extended floor panel and a connecting reinforcing member. The extension floor panel is supported in a cantilever manner by the cab floor panel, extends rearward of the vehicle from the cab supported portion, and constitutes the floor surface of the rear extension portion of the cab. The connecting reinforcing member connects and reinforces the cab floor panel and the extension floor panel.
上記構成では、キャブフロアパネルと延長フロアパネルとを連結して補強する連結補強部材を備えるので、延長フロアパネルに作用する荷重を、連結補強部材を介してキャブフロアパネルに分散することができ、キャブの後方延長部の支持剛性を確保することができる。
In the above configuration, since the connecting reinforcing member that connects and reinforces the cab floor panel and the extended floor panel is provided, the load acting on the extended floor panel can be distributed to the cab floor panel via the connecting reinforcing member, and the support rigidity of the rear extension of the cab can be ensured.
本開示の第２の態様は、第１の態様のキャブ後部構造であって、キャブフロアパネルは、後端部で車幅方向に沿って起立するフロア後面部を有する。フロア後面部には、延長フロア固定部と、延長フロア固定部よりも下方の第１連結部と、が設けられる。延長フロアパネルには、フロア後面部の延長フロア固定部に固定される延長フロア前端部と、延長フロア前端部よりも車両後方の第２連結部と、が設けられ、延長フロア前端部が延長フロア固定部に固定されることによって延長フロアパネルがキャブフロアパネルに片持ち状に支持される。連結補強部材は、フロア後面部の第１連結部に固定される第１固定部と、第１固定部の後斜め上方で延長フロアパネルの第２連結部に固定される第２固定部と、を有し、第１連結部と第２連結部とを直線状に連結する。
A second aspect of the present disclosure is the cab rear portion structure of the first aspect, wherein the cab floor panel has a floor rear surface portion that stands up along the vehicle width direction at the rear end portion. An extension floor fixing portion and a first connecting portion below the extension floor fixing portion are provided on the floor rear surface portion. The extended floor panel is provided with an extended floor front end portion fixed to the extended floor fixed portion of the rear surface portion of the floor, and a second connecting portion located rearward of the vehicle from the extended floor front end portion, and the extended floor front end portion is fixed to the extended floor fixed portion, thereby supporting the extended floor panel in a cantilever manner on the cab floor panel. The connecting reinforcing member has a first fixing portion fixed to the first connecting portion of the floor rear surface portion, and a second fixing portion fixed to the second connecting portion of the extended floor panel obliquely rearwardly above the first fixing portion, and linearly connects the first connecting portion and the second connecting portion.
上記構成では、延長フロアパネルの第２連結部が連結補強部材によって前斜め下方から支持された状態となるので、延長フロアパネルに作用する下方への荷重を、連結補強部材を介して効率良くフロア後面部に伝達することができる。
In the above configuration, the second connecting portion of the extended floor panel is supported obliquely from below by the connecting reinforcing member, so that the downward load acting on the extended floor panel can be efficiently transmitted to the rear surface of the floor via the connecting reinforcing member.
本開示のキャブ後部構造によれば、キャブリヤ被支持部よりも車両後方へ延びるキャブの後方延長部の床面がキャブフロアパネルに片持ち状に支持される車両において、キャブの後方延長部の強度を確保することができる。
According to the cab rear portion structure of the present disclosure, it is possible to ensure the strength of the rearwardly extending portion of the cab in a vehicle in which the floor surface of the rearwardly extending portion of the cab extending toward the rear of the vehicle from the cab supported portion is cantilevered on the cab floor panel.
以下、本開示の一実施形態について図面を参照して説明する。なお、以下の説明において、前後方向は車両の前後方向を意味し、左右方向は車両前方を向いた状態での左右方向を意味する。図中の矢印前後は車両の前後方向を、矢印上下は上下方向を、矢印左右は車幅方向をそれぞれ示す。また、各部材に関する方向は、車両に組付けられた状態での方向である。
An embodiment of the present disclosure will be described below with reference to the drawings. In the following description, the front-rear direction means the front-rear direction of the vehicle, and the left-right direction means the left-right direction when the vehicle faces forward. In the drawings, the front and rear arrows indicate the vehicle front-rear direction, the up and down arrows indicate the vertical direction, and the left and right arrows indicate the vehicle width direction. Also, the direction of each member is the direction when it is assembled to the vehicle.
図１に示すように、本開示に係るキャブ後部構造は、例えば、キャブ２が概ねエンジン（図示省略）の上方に配置されるキャブオーバー型の車両１に適用される。車両１は、車幅方向両側で車両前後方向に延設された車体フレーム３と、車体フレーム３にチルト可能に支持されるキャブ２と、キャブ２の後方で車体フレーム３の後部に下方から支持される荷台４とを備える。本実施形態の車両１は、荷台４の上方が開放された平ボディタイプのトラックである。
As shown in FIG. 1, the cab rear portion structure according to the present disclosure is applied, for example, to a cab-over type vehicle 1 in which the cab 2 is arranged generally above the engine (not shown). The vehicle 1 includes a vehicle body frame 3 extending in the longitudinal direction of the vehicle on both sides in the vehicle width direction, a cab 2 tiltably supported by the vehicle body frame 3, and a cargo bed 4 supported by the rear part of the vehicle body frame 3 from below behind the cab 2. - 特許庁The vehicle 1 of the present embodiment is a flat-body truck with an open loading platform 4 above.
キャブ２は、キャブ前面部５、左右のキャブ側面部６、キャブ後面部７、キャブ上面部８、及びキャブ下面部９によって箱状に形成され、その内部には車室１０が区画される。キャブ２の前側の下部は、キャブフロントマウント１１を介して車体フレーム３の前端部に回転自在に支持される。キャブ２の後側の下部の車幅方向両側には、左右のキャブリヤ被支持部１２が設けられ、キャブリヤ被支持部１２は、車体フレーム３側のキャブリヤマウント１３に下方から支持される。
The cab 2 is formed in a box shape by a cab front surface portion 5, left and right cab side surface portions 6, a cab rear surface portion 7, a cab upper surface portion 8, and a cab lower surface portion 9, and a compartment 10 is defined inside. A front lower portion of the cab 2 is rotatably supported by the front end portion of the vehicle body frame 3 via a cab front mount 11 . Right and left cab supported parts 12 are provided on both sides in the vehicle width direction of the rear lower part of the cab 2 , and the cab supported parts 12 are supported from below by cab mounts 13 on the body frame 3 side.
本実施形態のキャブ２は、キャブリヤ被支持部１２よりも車両後方へ延びる後方延長部１４を有する。キャブ２の後方延長部１４は、キャブリヤ被支持部１２よりも車両後方へ車室１０を拡張する。
The cab 2 of this embodiment has a rear extension portion 14 that extends to the rear of the vehicle from the cab supported portion 12 . The rear extension portion 14 of the cab 2 expands the passenger compartment 10 rearward of the vehicle beyond the cab supported portion 12 .
図１及び図２に示すように、キャブ下面部９は、キャブフロアパネル１５と、左右のフロアアンダーフレーム１６と、延長フロアパネル１７とを備える。キャブフロアパネル１５は、フロア前部１８と、フロア前部１８の後端縁部から後斜め上方へ延びるフロア中間部１９と、フロア中間部１９の後端縁部から車両後方へ延びるフロア後部２０と、フロア後部２０の後端縁部から車幅方向に沿って上方へ起立するフロア後縦面部（フロア後面部）２１とを有する。
As shown in FIGS. 1 and 2, the cab lower surface portion 9 includes a cab floor panel 15, left and right floor underframes 16, and an extension floor panel 17. The cab floor panel 15 has a front floor portion 18, an intermediate floor portion 19 extending rearward and obliquely upward from a rear edge portion of the front floor portion 18, a rear floor portion 20 extending rearward of the vehicle from a rear edge portion of the intermediate floor portion 19, and a rear vertical surface portion (floor rear surface portion) 21 rising upward along the vehicle width direction from the rear edge portion of the rear floor portion 20.
左右のフロアアンダーフレーム１６は、車幅方向に離間して車両前後方向に延び、キャブフロアパネル１５の下面に固定される。左右のフロアアンダーフレーム１６の後端部には、キャブリヤ被支持部１２が設けられる。すなわち、キャブリヤ被支持部１２は、キャブフロアパネル１５の後端部の下方に設けられる。
The left and right floor underframes 16 are spaced apart in the vehicle width direction, extend in the vehicle front-rear direction, and are fixed to the lower surface of the cab floor panel 15 . At the rear end portions of the left and right floor underframes 16, the cab-supported portions 12 are provided. That is, the cab floor supported portion 12 is provided below the rear end portion of the cab floor panel 15 .
延長フロアパネル１７は、キャブフロアパネル１５のフロア後部２０よりも上方且つ後方に配置され、その前端部（延長フロア前端部１７Ａ）がキャブフロアパネル１５のフロア後縦面部２１に固定されることにより、キャブフロアパネル１５に片持ち状に支持される。延長フロアパネル１７は、キャブリヤ被支持部１２よりも車両後方へ延び、キャブ２の後方延長部１４の床面を構成する。
The extended floor panel 17 is arranged above and behind the floor rear portion 20 of the cab floor panel 15, and its front end portion (extended floor front end portion 17A) is fixed to the floor rear vertical surface portion 21 of the cab floor panel 15, thereby being cantilevered on the cab floor panel 15. The extension floor panel 17 extends toward the rear of the vehicle from the cab 2 supported portion 12 and constitutes the floor surface of the rear extension portion 14 of the cab 2 .
キャブ２の後方延長部１４によって拡張された車室１０の後部空間２２は、キャブフロアパネル１５のフロア後部２０に取付けられた座席２３のシートバック２４の後方への傾動を許容する（リクライニング可能とする）リクライニングスペースとなる。また、車室１０の後部空間２２は、延長フロアパネル１７上に荷物２５を置く空間としても利用可能である。
The rear space 22 of the passenger compartment 10 expanded by the rear extension portion 14 of the cab 2 serves as a reclining space that allows the seat back 24 of the seat 23 attached to the floor rear portion 20 of the cab floor panel 15 to tilt rearward (make it reclinable). In addition, the rear space 22 of the passenger compartment 10 can also be used as a space for placing luggage 25 on the extended floor panel 17 .
キャブ２の後方延長部１４の上面部と車幅方向両側の側面部は、キャブ上面部８の後部と左右のキャブ側面部６の後部とによって構成される。後方延長部１４の後面部は、キャブ後面部７によって構成され、キャブ後面部７は、延長フロアパネル１７の後端縁部から上方へ延びる。キャブが後方延長部１４を備えない車両を製造する場合には、延長フロアパネル１７を設けず、キャブ上面部８及び左右のキャブ側面部６を車両後方に延長せずに、キャブ後面部７をキャブフロアパネル１５のフロア後縦面部２１の上端部から上方へ延びるように配置する。後方延長部１４を備える車両１と備えない車両とを、キャブリヤ被支持部１２の位置を変更せずに製造することができるので、キャブ側及び車体側の設計変更を少なく抑えることができる。
The upper surface portion of the rear extension portion 14 of the cab 2 and the lateral side portions on both sides in the vehicle width direction are formed by the rear portion of the cab upper surface portion 8 and the rear portions of the left and right cab side portions 6 . A rear surface portion of the rear extension portion 14 is constituted by a cab rear surface portion 7 which extends upward from a rear end edge portion of the extension floor panel 17 . When manufacturing a vehicle in which the cab does not have the rear extension part 14, the extension floor panel 17 is not provided, the cab upper surface part 8 and the left and right cab side parts 6 are not extended rearward of the vehicle, and the cab rear surface part 7 is arranged to extend upward from the upper end part of the floor rear vertical surface part 21 of the cab floor panel 15. - 特許庁Since the vehicle 1 with the rear extension part 14 and the vehicle without the rear extension part 14 can be manufactured without changing the position of the cab supported part 12, design changes on the cab side and the vehicle body side can be kept to a minimum.
キャブ２の後方延長部１４の下方（延長フロアパネル１７の下方）は、荷台４側の積荷空間として利用され、荷台４の床面２６は、キャブ後面部７よりも車両前方に延びる（図１参照）。
The space below the rear extension 14 of the cab 2 (below the extended floor panel 17) is used as a cargo space on the side of the cargo bed 4, and the floor surface 26 of the cargo bed 4 extends further forward of the vehicle than the cab rear surface 7 (see FIG. 1).
図４及び図５に示すように、キャブフロアパネル１５のフロア後縦面部２１には、フロア後縦面部２１の上端縁部から車両後方へ曲折して延びるフロア後端上面部（延長フロア固定部）２７が形成されている。延長フロアパネル１７の延長フロア前端部１７Ａは、フロア後端上面部２７に載置されて上方から重なり、フロア後端上面部２７に溶接等によって固定される。
As shown in FIGS. 4 and 5, the floor rear vertical surface portion 21 of the cab floor panel 15 is formed with a floor rear end upper surface portion (extended floor fixing portion) 27 extending from the upper edge portion of the floor rear vertical surface portion 21 to the rear of the vehicle by bending. The extended floor front end portion 17A of the extended floor panel 17 is placed on the floor rear end upper surface portion 27, overlaps from above, and is fixed to the floor rear end upper surface portion 27 by welding or the like.
