Description

[Detailed Description of the Invention] The present invention relates to a steady rest structure for a radiator mounted on a vehicle.

Conventionally, in a vehicle such as an agricultural tractor, a radiator fan is provided near the front of the engine, a radiator main body is provided in front of the fan, and auxiliary equipment such as a battery is further provided in front of the radiator main body. The radiator fan was blowing air toward the front to prevent high-temperature exhaust air from flowing into the driver's seat. Therefore, batteries and the like are adversely affected by the high-temperature exhaust air discharged from the radiator, resulting in a shortened lifespan.

Therefore, the above problem was solved by providing a large space between the engine and the radiator fan and arranging a battery or the like in this space. However, conventionally, the lower part of the radiator body was fixed to the vehicle.
The upper part was fixed by a cooling water circulation hose that connects the radiator body and the engine.
As the distance between the engine and the radiator becomes longer, it becomes difficult to secure the upper part of the radiator body with just a hose, and a complicated structure has to be used to stabilize the upper part.

Therefore, the present invention was devised in view of the above problems, and an object of the present invention is to provide a radiator steady rest structure that is extremely simple in structure and can prevent the upper part of the radiator main body from swinging. Therefore, its characteristic feature is that a wide space is provided between the engine 2 and the radiator fan 5 within the bonnet 8, the battery 4 is disposed in this space, and the radiator main body 6 is disposed in front of the radiator fan 5. In the vehicle radiator steady rest structure, a support frame body 14 rotatably supports the radiator fan 5 and the battery 4.
A joint pipe 30 is fixed to the support frame 14, and between the joint pipe 30 and the radiator main body 6,
Cooling water circulation hoses 29a and 29b are connected between the joint pipe 30 and the engine 2.

By providing the uneven strips 26 along the vertical direction on the lower side plate 12 in this way, compared to horizontal uneven stripes, it is possible to prevent rainwater, dirt, etc. from accumulating, and the space can be used to install various protruding equipment. can be stored.

The lower part of the radiator main body 6 disposed in front of the radiator fan 5 is placed and fixed on a radiator support frame 28 horizontally installed between the front axle frames 3. A cooling water circulation hose 29 extends from the upper part of the radiator body 6, and the hose 29 is connected to the engine 2. A joint pipe 30 is interposed in the middle of this hose 29, and the radiator side hose 2
9a and an engine side hose 29b. As shown in FIG.
It is fixed by 1. Since the upper part of the radiator main body 6 is supported by the joint pipe 30 via the hose 29a, swinging is prevented.

As shown in FIGS. 1 and 4, the radiator body 6
A water inlet 32 is provided in the upper part of the water inlet 3.
The top plate 9 corresponding to No. 2 is provided with an opening 34 having a lid 33 that can be opened and closed. A shielding member 35 that closes a gap between the outer peripheral surface of the radiator main body 6 and the inner peripheral surface of the bonnet 8 is attached to a frame member 36 of the radiator main body 6. The shielding member 35 is made of sponge or the like. Shielding member 35 around water inlet 32
is detoured rearward and abuts against the lower surface of the opening periphery so that water can be poured from the opening 34 into the water inlet 32.
Therefore, due to the radiator main body 6 and the shielding member 35,
The inside of the bonnet 8 is completely divided into a cooling air intake side A and an exhaust side B, and the cooling air from the radiator fan 5 is prevented from being blown back to the cooling air intake side after passing through the radiator body 6. Therefore, a decrease in the cooling efficiency of the radiator is prevented. Note that the shielding member 35 around the opening 34 may be provided in front of the water inlet 32.
