【考案の詳細な説明】
本考案はフオークリフトやシヨベルローダのト
ルクコンバータオイルの冷却装置に関するもので
ある。[Detailed Description of the Invention] The present invention relates to a cooling device for torque converter oil in a forklift or a shovel loader.
フオークリフトやシヨベルローダには動力伝達
方式にクラツチ式とトルクコンバータ式があるが
トルクコンバータ式の場合、第１図に示すように
トルクコンバータａ用のオイルを冷却必要量のみ
ポンプｂによつて循環させて動力を伝達してい
る。 Forklifts and shovel loaders have two power transmission systems: a clutch type and a torque converter type. In the case of a torque converter type, as shown in Figure 1, only the amount of oil required for cooling the torque converter a is circulated by a pump b. power is transmitted.
このとき、トルクコンバータａのオイルは若干
の出力損失のため油温が上昇するのでトルクコン
バータａの外周にフインｃを設け通風放熱によつ
てオイルを冷却している。 At this time, the oil temperature of the oil in the torque converter a rises due to a slight output loss, so fins c are provided around the outer periphery of the torque converter a to cool the oil by ventilation heat radiation.
しかし、エンジンの出力が比較的大きく、また
負荷の変動も大きくなつてくるとこのフインｃだ
けでは冷却能力が不足するため、別にトルクコン
バータオイルクーラｄを設ける場合がある。 However, when the output of the engine is relatively large and the fluctuation of the load becomes large, the cooling capacity of the fins c alone is insufficient, so a torque converter oil cooler d may be separately provided.
その場合、従来は、エンジン冷却用のラジエー
タｅのタンクｆ内にトルコンオイルのパイプｇを
通する方法などが採られてきた。 In this case, conventional methods have been adopted such as passing a torque converter oil pipe g into a tank f of a radiator e for engine cooling.
しかし、このパイプ式では冷却能力が不足する
場合があり、そのときにはパイプ式にかえて多板
式のもの（第４図参照）を採用していたが、これ
はパイプ式のものに比べて高価になる欠点があつ
た。 However, this pipe type sometimes lacks cooling capacity, and in those cases, a multi-plate type (see Figure 4) is used instead of the pipe type, but this is more expensive than the pipe type. There was a drawback.
本考案は上記の事情に鑑みなされたものであつ
て、その目的とするところは構造が簡単で安価に
製作できしかも冷却能力の選択範囲を大きくする
ことが可能な車両の冷却装置を提供することにあ
る。 The present invention was devised in view of the above circumstances, and its purpose is to provide a cooling device for a vehicle that has a simple structure, can be manufactured at low cost, and can widen the range of cooling capacity selection. It is in.
以下、本考案を第５図および第６図を参照して
説明する。 Hereinafter, the present invention will be explained with reference to FIGS. 5 and 6.
図面１はラジエータである。ラジエータ１のタ
ンク２内にはトルコンオイルが流れるオイルクー
ラ３が設けてあり、またラジエータ１のコア部７
の前方には冷却器４が設けてあり、オイルクーラ
３の出口側は冷却器４の入口側に接続してある。 Drawing 1 shows a radiator. An oil cooler 3 through which torque converter oil flows is provided in the tank 2 of the radiator 1, and the core part 7 of the radiator 1
A cooler 4 is provided in front of the oil cooler 3, and the outlet side of the oil cooler 3 is connected to the inlet side of the cooler 4.
冷却器４はオイルクーラ３のもどり側の配管５
を蛇行させたものである。 The cooler 4 is a pipe 5 on the return side of the oil cooler 3.
It is a meandering version of
しかして、オイルクーラ３で冷却されたオイル
は冷却器４に入り、エンジン５のフアン６による
気流で更に冷却されてトルクコンバータにもど
る。 The oil cooled by the oil cooler 3 then enters the cooler 4, is further cooled by the airflow generated by the fan 6 of the engine 5, and returns to the torque converter.
なお冷却器４はラジエータ１の後方に設置して
もよい。 Note that the cooler 4 may be installed behind the radiator 1.
本考案は以上詳述したようになるから、オイル
クーラ３のもどり側もしくは入口側の配管を長く
してラジエータ１のコア部７の前、後面のいずれ
かに設置することにより冷却器４とすることがで
きて非常に構造が簡単でありながら安価に製作で
きるし、また冷却器４はラジエータ１のコア部の
前側あるいは後側の比較的広い所を利用して使用
でき冷却能力の選択範囲も大きくなる。 Since the present invention has been described in detail above, the cooler 4 is constructed by lengthening the piping on the return side or inlet side of the oil cooler 3 and installing it either in front or at the rear of the core portion 7 of the radiator 1. It has a very simple structure and can be manufactured at low cost, and the cooler 4 can be used in a relatively wide space on the front or rear side of the core of the radiator 1, allowing for a wide selection of cooling capacities. growing.
