Description

[Technical Field]

[0001] The present invention relates to a utility vehicle. [Background technology]

[0002] As shown in Patent Document 1, there is a multipurpose vehicle in which an engine is provided at the rear of the vehicle body (airframe). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-100173 Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, a radiator is installed at the front of the vehicle and is connected to the engine by a coolant circulation path to cool the engine. However, in the rear of the vehicle, the engine may not be cooled efficiently due to heat dissipation from the engine and engine accessories such as the exhaust muffler being trapped inside.

[0005] The present invention provides a multi-purpose vehicle that can cool the engine efficiently and inexpensively. [Means for solving the problem]

[0006] The multipurpose vehicle according to the present invention comprises: The vehicle is equipped with an engine located at the rear of the vehicle body, a radiator located at the front of the vehicle body and connected to the engine by a coolant circulation path, and a blower located around the engine to supply cooling air toward the engine.

[0007] With this configuration, the engine is cooled not only by the coolant circulating between the engine and the radiator, but also by the cooling air supplied by the blower. In addition, the cooling air supplied by the blower also flows around the engine, preventing heat buildup around the engine. Compared to a system with a sub-radiator, the blower can be installed inexpensively, as it does not require a coolant circulation path, making it possible to cool the engine efficiently and inexpensively.

[0008] In the present invention, The peripheral area is preferably located laterally outward of the engine on the vehicle body.

[0009] According to this configuration, the cooling air supplied to the engine by the air blower can be efficiently introduced from the outside of the vehicle body side, so that the engine can be efficiently cooled.

[0010] In the present invention, The blower preferably includes a rotary fan and an electric motor that drives the rotary fan.

[0011] According to this configuration, the blower device can be driven inexpensively by simply supplying power to the electric motor, so that the engine can be cooled inexpensively.

[0012] In the present invention, It is preferable that a battery be provided on one side of the air blower.

[0013] According to this configuration, the battery is located near the blower, so the electrical circuit connecting the electric motor and the battery can be simplified, making it possible to cool the engine at low cost. [Brief explanation of the drawings]

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, with respect to the body of the multipurpose vehicle, the direction of arrow F shown in Figures 1 and 2 is referred to as the "front direction of the body," the direction of arrow B shown in Figures 1 and 2 is referred to as the "rear direction of the body," the direction of arrow U shown in Figure 1 is referred to as the "upward direction of the body," the direction of arrow D shown in Figure 1 is referred to as the "downward direction of the body," the direction of arrow L shown in Figure 2 is referred to as the "leftward direction of the body," and the direction of arrow R shown in Figure 2 is referred to as the "rightward direction of the body." The left-right direction of the body corresponds to the width direction of the body.

[0016] [Overall configuration of multipurpose vehicle] The utility vehicle shown in FIGS. 1 and 2 is used for multiple purposes, such as transporting luggage and recreation. The utility vehicle has a body 4, which includes a body frame 1, front wheels 2 steerably and drivably mounted at the front of the body frame 1, and a pair of left and right rear wheels 3 drivably mounted at the rear of the body frame 1. A front lid 5 is provided at the front of the body 4. A driver's section 6 is formed between the front wheels 2 and the rear wheels 3 of the body 4. The driver's section 6 includes a driver's seat 16, a steering wheel 17 for steering the front wheels 2, and a cabin 7 that covers the passenger space. A cargo bed 8 is provided at the rear of the body 4. An engine 9 and a driving transmission 10 are provided at the rear of the body 4. The engine 9 and the driving transmission 10 are inputted from the engine 9, and the driving power is changed and output to the front wheels 2 and the rear wheels 3. The driving transmission 10 extends rearward from the rear of the engine 9. The engine 9 and the driving transmission 10 are located in a position that is covered from above by the cargo bed 8.

[0017] [Engine cooling structure] As shown in Figures 1, 2, and 3, a radiator 11 is provided in the front part of the vehicle body 4, and the radiator 11 and engine 9 are connected by a coolant circulation path 12. The radiator 11 is covered from above by a front lid 5. A rotary fan 13 is provided behind the radiator 11 and can be driven by an electric motor (not shown). Cooling air is introduced into the radiator 11 from the front of the vehicle body 4 by the rotation of the rotary fan 13, and the introduced cooling air cools the coolant located inside the radiator 11. The cooled coolant is supplied to the engine 9 through an outward path 12a of the coolant circulation path 12, and the coolant that has cooled the engine 9 is returned to the radiator 11 through a return path 12b of the coolant circulation path 12, thereby cooling the engine 9.

[0018] 2 and 3, a blower 14 is provided around the engine 9. Cooling air is supplied to the engine 9 by the blower 14 to cool the engine 9. The cooling air supplied by the blower 14 also flows around the engine 9, preventing heat from building up around the engine 9.

[0019] 2 and 3, the area around the engine 9 where the blower 14 is provided is located laterally outward of the vehicle body relative to the engine 9. The blower 14 introduces cooling air to be supplied to the engine 9 from the lateral side of the vehicle body.

[0020] 2 and 3, the blower 14 includes a rotary fan 14a and an electric motor 14b connected to the rotary fan 14a. In the blower 14, the rotary fan 14a is driven by the electric motor 14b, and cooling air is introduced from outside the vehicle body by the rotary fan 14a and supplied toward the engine 9.

[0021] As shown in Figures 2 and 3, a battery 15 is provided on the side of the blower 14. This battery 15 is connected to the electric motor 14b, and power is supplied from the battery 15 to the electric motor 14b. As shown in Figure 1, a side cover 18 is provided on the side of the vehicle body 4, covering the blower 14 and the battery 15 from the lateral outer side. The side cover 18 is formed with an air intake port that allows cooling air to be introduced by the blower 14. The air intake port is equipped with a mesh-like dustproof member.

[0022] [Another embodiment] (1) In the above-described embodiment, the blower device 14 is provided at a location located laterally outward from the engine 9, but it may also be provided at a location located forward from the engine 9, or rearward from the engine 9, or above the engine 9.

[0023] (2) In the above embodiment, the blower 14 is driven by the electric motor 14b. However, the blower 14 may be driven by the power of the engine 9.

[0024] (3) In the above embodiment, the battery 15 is provided to the side of the blower 14, but it may be provided in any location, such as above the blower 14, in front of the blower 14, or behind the blower 14. [Industrial Applicability]
