Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0036] exist figure 1 In the figure, as one embodiment of the rubber pad for fuel tank constructed according to the present invention, a rubber pad for fuel tank 10 for supporting a fuel tank of an automobile is shown. The tank rubber pad 10 has a structure in which two combined cylindrical rubbers 14 a , 14 b are attached to the inner shaft member 12 . In addition, the inner shaft member 12 is directly fixed to the mounting piece 16 on the vehicle body side, and the inner shaft member 12 penetrates the mounting hole 20 provided in the support portion 18 on the fuel tank side, and is indirectly mounted through the two combined cylindrical rubbers 14a, 14b. The fuel tank is attached to the fuel tank, and the fuel tank (not shown) is supported by vibration isolation of the vehicle body. In addition, the fuel tank is supported on the vehicle body at multiple places by a...

Abstract

Provided is a tank rubber cushion which has a novel structure to achieve a sufficiently high support spring rigidity in the vertical direction and a low spring property in the horizontal direction without complicating the structure or increasing parts counts. Two divided pieces of cylindrical rubber (14) are fitted over an inner axial member (12) which is inserted into an insertion hole (20) of a support portion (18). Each divided piece of cylindrical rubber (14) is provided with an axial vibration damping rubber portion (40) which is interposed between the axially opposed surfaces of a flange portion (38, 28) and the support portion (18), and a tubular axially perpendicular vibration damping rubber portion (42) which is interposed between the axially perpendicular opposed surfaces of the inner axial member (12) and the support portion (18). The axially perpendicular vibration damping rubber portion (42) of each divided piece of cylindrical rubber (14) is provided with circumferentially recessed and projected portions (48, 50) which have partially different diameters along the circumference, so that the outer circumferential surface of the inner axial member (12) and the inner circumferential surface of the support portion (18) are assembled together with gaps (52, 54) present therebetween at the recessed and projected portions (48, 50).

Description

technical field [0001] The invention relates to a rubber pad for a fuel tank for vibration-insulating and supporting a fuel tank on a vehicle body. Background technique [0002] Conventionally, in order to support the fuel tank on the vehicle body, a rubber gasket for the fuel tank has been used. For example, Japanese Patent Application Laid-Open No. 2009-67108 (Patent Document 1) discloses a rubber gasket for a fuel tank. [0003] In addition, in order to be able to stably supply fuel into the fuel tank, or to reduce the transmission of vibration to the vehicle body due to the displacement of the fuel tank itself, it is desired that the rubber pad for the fuel tank has vibration isolation support performance, and the rubber pad for the fuel tank is required to reduce fuel consumption. The sound of fuel flowing in the tank. Then, in order to meet these requirements, it is generally considered effective to ensure the support elastic stiffness (Japanese: ばね rigidity) of the ...
