Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for an automobile radiator.

As shown in FIG. 1, a radiator 1 has a mounting rubber 4 attached to a pin 3 implanted in a vehicle body member 2 at its lower part.
At the same time, insert the upper part into the radiator panel 5 through the rubber 6 and the bolt 7.
It is normal to install it by tightening and fixing it.

In such a radiator mounting structure, conventionally, as shown in FIG. 2, an annular groove 6a of an appropriate depth is formed on the outer peripheral surface of the upper mount rubber 6.
Fit the peripheral edge of the mounting hole 5a provided in the radiator panel 5 into the annular groove 6a, fit the cylinder 8 of an appropriate length into the bolt insertion hole of the mount rubber 6, and insert the cylinder 8 through the plate 9, washer 10, etc. Nut 11 fixing bolt 7 to upper member 1a of radiator 1
The mount rubber 6 is screwed into the mounting hole 5a of the radiator panel 5 on both sides of the annular groove 6a and the periphery of the mounting hole 5a of the radiator panel 5 is clamped with a predetermined pressure.

However, in such a conventional configuration, the radiator can be installed by simply setting the radiator in a predetermined position and screwing in the bolts 7 from the front side of the vehicle body. Although the radiator installation workability is extremely good, Radiator 1 due to vibration of
The downward load of the radiator 1 is received by the compression of the lower mount rubber 4 via the lower member 1b and the bracket 1b' of the radiator 1, and also by the frictional force of the upper mount rubber 6 holding the radiator panel 5. The upward load is supported only by the frictional force of the upper mount rubber 6, and if a vertical load greater than the frictional force is repeated, the radiator panel holding part of the upper mount rubber 6 will be damaged, causing damage to the upper mount. This can cause backlash and eventually cause problems such as cracks in the radiator.

The present invention provides a structure that can solve the above-mentioned conventional problems with extremely simple measures.

That is, in the present invention, as shown in FIGS. 3 and 4, the outer peripheral surface of the upper mount rubber 6 is attached to the outer periphery of the mounting hole 5a of the radiator panel 5 that is fitted into the annular groove 6a of the upper mount rubber 6. A cylindrical protrusion 5b is formed so as to wrap around the cylindrical protrusion 5b.

As mentioned above, the mounting hole 5a of the radiator panel 5
By forming the cylindrical protrusion 5b on the outer periphery of the periphery, the cylindrical protrusion 5b wraps around the outer circumferential surface 6b near the radiator 1 from the annular groove 6a of the mount rubber 6 in the installed state. At the upper mount part, the vertical load of There is almost no damage to the parts, and the durability of the mount rubber can be significantly improved.

In FIG. 3, the structure of the lower mount portion of the radiator 1 is the same as that of the conventional one shown in FIG. 2, so a detailed explanation will be omitted.

As described above, the present invention has an extremely simple structure in which only a cylindrical protrusion is formed on the outer periphery of the mounting hole of the radiator panel to which the upper part of the radiator is attached, without impairing the workability of mounting the radiator in the slightest. , the durability of the mount rubber is significantly improved, and the radiator can be accurately supported for a long period of time, and the practical effect is extremely large.

Claims (1)

[Scope of utility model registration request] The lower part of the radiator is inserted and locked from above into a pin provided on a vehicle body member through a mounting rubber, and a cylindrical protrusion is formed on the outer periphery of the mounting hole of the radiator panel that supports the upper part of the radiator. When the peripheral edge of the mounting hole is fitted into an annular groove provided on the outer periphery of the upper mount rubber, the cylindrical protrusion surrounds the outer periphery of the upper mount rubber, and the upper mount rubber is attached to the upper part of the radiator by bolts. By tightening and fixing the radiator, the vertical load of the radiator is received by both the frictional force between the annular groove of the upper mount rubber and the peripheral edge of the radiator panel mounting hole held therein, and the outer circumferential surface of the upper mount rubber. Radiator mounting structure.
