　本発明は、電動作業車両に関する。 The present invention relates to an electric work vehicle.
　従来から、環境負荷低減の観点に着目し、内燃機関に代えて走行用動力源としてモータを利用する電気自動車の開発が進んでいる。このような電動車両においては、当該モータを駆動するために駆動用のバッテリが搭載され、当該バッテリから当該モータへ電力を供給することにより、車両を走行するために必要となる動力が得られる。近年、このような電動車両に関し、トラック等の商用車の分野においても、その開発が行われている。例えば、特許文献１には、衝突安全性を向上することができる商用車向けのバッテリボックスの保持構造が開示されている。 From the viewpoint of reducing the environmental load, the development of electric vehicles that use a motor as a driving power source instead of the internal combustion engine has been progressing. In such an electric vehicle, a battery for driving is mounted to drive the motor, and by supplying electric power from the battery to the motor, power required for traveling the vehicle can be obtained. In recent years, such electric vehicles have been developed in the field of commercial vehicles such as trucks. For example, Patent Document 1 discloses a battery box holding structure for a commercial vehicle that can improve collision safety.
　ところで、塵芥車両、冷蔵車両、ダンプ車両、ミキサ車両、消防車両など、所定の作業を行う作業装置が架装された作業車両は、一般的に、内燃機関の回転動力の少なくとも一部を取り出して油圧ポンプやコンプレッサ等の作動動力源とするＰＴＯ装置（Power Take
Off）により当該作業装置を駆動させている。このような作業車両を電動化する場合には、例えば、電気トラックのバッテリから供給される電力をＰＴＯ装置で動力に変換し、車両に搭載した作業装置に動力を伝達することになる。 By the way, a work vehicle such as a dust vehicle, a refrigerating vehicle, a dump vehicle, a mixer vehicle, a fire engine vehicle or the like, on which a work device for performing a predetermined work is installed, generally takes out at least a part of the rotational power of the internal combustion engine. PTO device (Power Take) that uses hydraulic pumps, compressors, etc.
Off) is driving the work device. When electrifying such a work vehicle, for example, the electric power supplied from the battery of the electric truck is converted into power by the PTO device, and the power is transmitted to the work device mounted on the vehicle.

　しかしながら、上記のような電動作業車両は、既存の電動トラックに対してオプションとしてＰＴＯ装置やこれに付随する補機類を搭載する必要があることからレイアウトの制約を受ける場合があり、レイアウトの違いによる車両のバリエーションが増加することにより開発コストの上昇を招来する虞が生じる。また、電動作業車両において、搭載されたバッテリからＰＴＯ装置へ電力を供給する高電圧ケーブルは、通常の電気ケーブルに比して安全性及びメンテナンス性に対する要求が高く且つ高価であるため、配策によってはこれらの要求を満たせない虞が生じる。 However, the electric work vehicle as described above may be subject to layout restrictions because it is necessary to mount a PTO device or auxiliary equipments associated therewith as an option on an existing electric truck, and the layout may differ. Due to the increase in vehicle variations due to the above, there is a risk that the development cost will increase. Further, in an electric work vehicle, a high-voltage cable that supplies electric power from a mounted battery to a PTO device has higher requirements for safety and maintainability and is more expensive than an ordinary electric cable. May not meet these requirements.
　本発明は、このような状況に鑑みてなされたものであり、その目的とするところは、高電圧ケーブルの配策を簡素化し、且つ搭載される補機類のレイアウトを共通化することができる電動作業車両を提供することにある。 The present invention has been made in view of such a situation, and an object of the present invention is to simplify the arrangement of high-voltage cables and to share the layout of auxiliary equipments to be mounted.

In the present embodiment, as will be described later in detail, the PTO unit 30 rotationally drives the compressor 33 (not shown in FIG. 1) by the rotational power to supply the refrigerant to the refrigerator 22. More specifically, the PTO unit 30 circulates the refrigerant in the refrigerator 22 through a refrigerant circuit 30a provided along the surface of the freezing loading portion 21 facing the cab 15.
　次に、車体１０の構成について、より具体的に説明する。図２は、車体１０及びＰＴＯユニット３０の構成を示す斜視図である。より詳しくは、図２は、架装体２０を取り外した状態の電動作業車両１を右斜め後方から俯瞰したときの斜視図である。 Next, the structure of the vehicle body 10 will be described more specifically. FIG. 2 is a perspective view showing the configurations of the vehicle body 10 and the PTO unit 30. More specifically, FIG. 2 is a perspective view of the electric work vehicle 1 with the body 20 removed, as viewed from an obliquely right rear side.

The left side rail 11L and the right side rail 11R are connected to each other. A so-called ladder frame including a plurality of cross members 11C is configured.
　バッテリ１２は、上記したように、車体１０の走行駆動、及び電動補機類の駆動に必要な電力を供給する二次電池であり、双方に必要とされる電力を蓄えるために比較的大型で大容量のバッテリモジュール（図示せず）を内部に複数備える。また、バッテリ１２は、車両長手方向Ｘに対して前方及び後方にそれぞれ独立して電力を供給できるよう構成されている。 As described above, the battery 12 is a secondary battery that supplies electric power required to drive the vehicle body 10 and to drive electric auxiliaries, and is relatively large in size to store the electric power required for both. A plurality of high-capacity battery modules (not shown) are provided inside. Further, the battery 12 is configured to be able to independently supply power to the front and the rear with respect to the vehicle longitudinal direction X.

It has a shape in which the substantially rectangular parallelepiped portion to be arranged is integrated, and has a shape in which the cross-sectional shape in a plane perpendicular to the vehicle longitudinal direction X is an inverted T shape. Then, the battery 12 is arranged so that the left side rail 11L and the right side rail 11R respectively pass through the stepped portion caused by the difference in width between the two portions. Thereby, the battery 12 effectively uses the space below the body 20 to increase the battery capacity. The shape of the battery 12 is not limited to this, and can be appropriately changed according to the required battery capacity and the layout of the vehicle body 10.

The high voltage cable 12c connecting the unit 30 and the power distribution unit 12b can be further shortened.
　そして、本発明の第１実施形態に係る電動作業車両１によれば、ＰＴＯユニット３０の全体がキャブ１５の凹部空間１５Ｂに収容されていることから、キャブ１５と冷凍積載部２１との互いの対向面を近接して配置することができ、冷凍積載部２１の容積の確保を阻害しないようにすることができる。 Further, according to the electric work vehicle 1 according to the first embodiment of the present invention, the entire PTO unit 30 is housed in the recessed space 15B of the cab 15, so that the cab 15 and the frozen loading portion 21 are separated from each other. The opposing surfaces can be arranged close to each other, and the securing of the volume of the frozen loading section 21 can be prevented.
　また、本発明の第１実施形態に係る電動作業車両１によれば、冷凍車用架装システムとしての架装体２０は、従来のエンジントラックにおけるＰＴＯ装置と同じく、架装体２０よりも車両長手方向Ｘの前方における車両フレーム１１のサイドレール間の位置から動力を取り出すことができる。このため、本発明の第１実施形態に係る電動作業車両１によれば、必要最小限の設計変更で既存の内燃機関向けの架装システムを流用することができるため、開発及び製造に係るコストを抑制しつつ、架装システム内での電気的安全性も容易に担保することができる。 Further, according to the electric work vehicle 1 according to the first embodiment of the present invention, the body 20 as a refrigerating vehicle bodywork system is a vehicle more than the body 20 as in the conventional PTO device in an engine truck. Power can be taken out from the position between the side rails of the vehicle frame 11 in the front in the longitudinal direction X. Therefore, according to the electric work vehicle 1 according to the first embodiment of the present invention, an existing bodywork system for an internal combustion engine can be diverted with a minimum necessary design change, and thus costs for development and manufacturing can be reduced. It is possible to easily secure electrical safety in the bodywork system while suppressing the above.
　さらに、本発明の第１実施形態に係る電動作業車両１は、ＰＴＯモータ３２及びコンプレッサ３３は、いずれも回転軸が車両長手方向Ｘを向くように車幅方向Ｙに並べて配置されている。これにより、本発明の第１実施形態に係る電動作業車両１によれば、キャブ１５の凹部空間１５ＢにおけるＰＴＯユニット３０の搭載性を向上させることができ、また、コンプレッサ３３を従来のエンジントラックに搭載される冷凍車用架装システムと同じ向きに設置することができるため、冷媒回路３０ａの変更も不要となる。 Further, in the electric work vehicle 1 according to the first embodiment of the present invention, the PTO motor 32 and the compressor 33 are both arranged side by side in the vehicle width direction Y so that the rotation axes thereof face the vehicle longitudinal direction X. As a result, according to the electric work vehicle 1 according to the first embodiment of the present invention, the mountability of the PTO unit 30 in the recessed space 15B of the cab 15 can be improved, and the compressor 33 can be used as a conventional engine truck. Since it can be installed in the same direction as the mounted refrigeration vehicle bodywork system, it is not necessary to change the refrigerant circuit 30a.

It is suspended on the rail 11L and the right side rail 11R, respectively.
また、それぞれのサイドバッテリ１２Ｄは、車両長手方向Ｘの前方領域に配電部１２Ｅが設けられている。そして、それぞれの配電部１２Ｅは、高電圧ケーブル１２Ｆを介してＰＴＯユニット３０に電力を供給する。これにより、本実施形態の電動作業車両５によれば、バッテリ１２が車両フレーム１１の両側にそれぞれ配置されるサイドバッテリ１２Ｄとして構成されている場合であっても、高電圧ケーブル１２Ｆの配策を簡素化し、且つ搭載される補機類のレイアウトを共通化することができる。 Further, each side battery 12D is provided with a power distribution unit 12E in a front region in the vehicle longitudinal direction X. Then, each power distribution unit 12E supplies power to the PTO unit 30 via the high voltage cable 12F. As a result, according to the electric work vehicle 5 of the present embodiment, even if the batteries 12 are configured as the side batteries 12D arranged on both sides of the vehicle frame 11, the high voltage cable 12F can be routed. It is possible to simplify and make common the layout of the auxiliary equipment to be mounted.
