DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator device for a vehicle.

[0002]

2. Description of the Related Art A radiator device used for a vehicle such as a motorcycle has an upper tank B and a lower tank C connected by a pair of left and right side members D and E, as in a radiator device A shown in FIG. In many cases, a plurality of cooling water pipes F are arranged in parallel between the upper tank B and the lower tank C. As a structure for supporting the radiator device A on the vehicle body side, the side member E may be fixed to a stay H provided on the vehicle body G, and the radiator device A may be supported in a cantilever state.

[0003]

However, when the radiator device A is supported in a cantilever manner as described above, the weight of the radiator device A itself and the violent vertical vibration during traveling of the vehicle cause the radiator device A to have the configuration shown in FIG. The radiator device A may be deformed as shown in FIG. When the radiator device A is deformed in this way, the free end side (side member D side) of the radiator device A always floats up and down with respect to the vehicle body G. In addition, fatigue fracture may occur at a joint portion with the cooling water pipe F, and internal cooling water may leak.

The present invention has been made to solve this problem. Even if the radiator device is supported in a cantilevered state, the radiator device is free from deformation due to its own weight, violent vertical running vibration, and the like. It is an object of the present invention to provide a radiator device for a vehicle, which has high performance.

[0005]

In order to achieve the above object, a vehicle radiator device according to the present invention comprises an upper tank and a lower tank connected by a pair of left and right side members, and a plurality of cooling water pipes between the upper tank and the lower tank. Are arranged in parallel, the overall shape is long in the vertical direction of the vehicle, and one side of the pair of left and right side members is supported by the vehicle body frame, so that the vehicle body In a radiator device for a vehicle supported by a frame, a side member supported on a body frame is elastically connected to two radiator bosses provided at an interval above and below the body frame via a cushion material. At the same time, the left and right side members are shaped like a cross in the range between the two radiator bosses. Was connected by a reinforcing member of one plate, it is characterized in that the connection position between the side members of the reinforcing member and the vehicle body frame side is brought close to each radiator bosses.

[0006]

With this construction, the rigidity of the radiator is greatly improved because the left and right side members are firmly connected by the cross-shaped reinforcing member and cannot be moved vertically. Therefore, even if the radiator device is supported on the vehicle body frame in a cantilevered state, deformation and fatigue damage due to the weight of the radiator device, severe vibration in the vertical direction, and the like are prevented, and durability is improved. Moreover, since the highly rigid radiator device is elastically supported by the vehicle body frame through the cushioning material, vibrations and impacts from the vehicle body frame are absorbed by the cushioning material and are not easily transmitted to the radiator device. The durability of the device is further increased.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a left side view of a motorcycle to which a radiator device for a vehicle according to the present invention is applied. In the motorcycle 1, an engine 3 is mounted in a central portion of a body frame 2, and a fuel tank 4 and a seat 5 are installed above the body frame 2.

5 is a side member 1 on one side (inside) of the radiator device 6.
8 is inserted through a cushion material 26 and fixed with bolts 27. For this reason, the radiator device 6 is elastically supported by the vehicle body frame 2 in a cantilever state. The radiator device 7 on the left side shown in FIG. 2 is also elastically cantilevered by the vehicle body frame 2.

Brackets 17a and 18a are formed on the side members 17 and 18 on the rear side of the radiator device 6 (7), and a nut 28 is fixed inside the brackets 17a and 18a.
Then, both ends of the reinforcing member 29 having, for example, a U-shaped cross section are attached to these bracket portions 17a and 18a by bolts 3.
1, the side members 17 and 18 are connected and fixed to each other. For this reason, the left and right side members 17 and 18 cannot relatively move, so that the rigidity of the radiator device 6 (7) is improved and the durability is increased.

FIG. 5 shows an overall embodiment of the present invention. In this embodiment, the radiator device 6 (7)
As in the case of FIG. 3, one side (inside) side member 18 is fixed to two radiator bosses 25 provided on the vehicle body frame 2 with a space therebetween by bolts via a cushion material, and cantilevered. In this state, it is elastically supported by the body frame 2.

Each of the side members 17 and 18 has
