TECHNICAL FIELD

[0001] The present application relates to a V-shaped radiator suspension soft pad. BACKGROUND

[0002] The existing traditional radiator suspension mostly adopts casting and machining process, so it has the disadvantages of low production efficiency, high waste rate and high cost. In addition, the radiator suspension is not comprehensive in limiting, which can easily cause fan damage in the use process; the radiator suspension has unreasonable design in rigidity, and the forward, backward, left, right, upward and downward translational modal is exactly in the 34-100Hz interval, which is completely coupled with the normal driving ignition modal of the engine, so there is a risk of NVH problem.

[0003] For example, CN201331139Y provides a radiator suspension module, the upper pad plate and the lower pad plate of the scheme are locked and matched in six directions, which has the advantages of compact structure, simple installation and reliability, but since the upper pad plate and the lower pad plate need to be produced by casting and machining process, there are problems of low production efficiency and high waste rate. SUMMARY

[0004] In order to solve the defects existing in the prior art, the present application provides a V-shaped radiator suspension soft pad, which has high production efficiency, low cost and effectively avoids the risk of NVH.

[0005] Therefore, the technical scheme of the present application is: a V-shaped radiator suspension soft pad, which comprises an upper support assembly and a lower support assembly, wherein the upper support assembly is located directly above the lower support assembly, the upper support assembly is connected with a radiator water tank through a radiator suspension soft pad support, and the lower support assembly is connected with a vehicle frame, characterized in that: the upper support assembly comprises an upper support and an inner support, wherein the inner support is located on the lower end face of the upper support close to the outer side, the inner support extends downward and is inclined to the inner side, a notch is arranged at the middle position of the lower end of the inner support, and the notch faces downward.

[0006] The lower support assembly comprises a lower support and an outer support, wherein the outer support is located on the upper end face of the lower support and is outside the inner support, the outer support extends upward and is inclined to the outer side, and a main rubber spring is vulcanized between the outer support and the inner support;

[0007] The lower support is provided with a gap corresponding to the notch, and the openings of the gap all face the outer side; the inner support is clamped at the gap of the lower support through the notch, the lower end of the inner support extends transversely after penetrating through the lower support, and a locking assembly is formed.

[0008] Further improvement is that: the inner support is two, in a symmetrical state, forming a "V" shape, and the corresponding outer support is also in a "V" shape, and the inner support falls on the main rubber spring of the outer support; the inner support is protruded inward at the middle position, forming a recess.

[0009] The outer support is provided with a convex arc at the position corresponding to the recess towards the inner side;

[0010] The rubber main spring is hung upside down in the recess and abuts against the convex arc.

[0011] Further improvement is that the rubber main spring is pre-vulcanized at the recess of the inner support and extends downwards along the outer wall of the inner support, so that the rubber is vulcanized on the inner wall and outer wall of the gap of the inner support and the corresponding notch.

[0012] Further improvement is that the inner side of the upper end surface of the upper support is further provided with a nut, which is integrated with the upper support through welding or riveting process;

[0013] The upper support is provided with a first mounting hole at the position corresponding to the nut.

[0014] Further improvement is that the outer side of the lower support extends outwardly and downwardly to form a clearance cavity and a mounting plate, the clearance cavity is provided with a reinforcing rib at the position corresponding to the gap, and the mounting plate is provided with a second mounting hole.

[0015] Further improvement is that the upper support, the lower support, the inner support, the outer support and the reinforcing rib are all stamping parts, wherein the upper support and the inner support are integrated into an upper support assembly through welding process, and the outer support, the lower support and the reinforcing rib are integrated into a lower support assembly through welding process.

[0016] Beneficial effects:

[0017] The upper support, the lower support, the inner support, the outer support and the reinforcing rib are all stamping parts, the upper support and the inner support are welded into an upper support assembly, and the outer support, the lower support and the reinforcing rib are welded into a lower support assembly, the reinforcing rib strengthens the strength of the lower support assembly, and the stamping part welding process has the advantages of light weight, low cost and higher production efficiency compared with the casting machining process.

[0018] After the radiator suspension rubber main spring adopts V-shaped structure, the two rubber blocks on one side evenly share the water tank inertia and mass, the stress concentration problem of the rubber is avoided in structure, so as to reduce the stiffness to obtain ideal modal distribution, and the flexible body durability risk is reduced in redesign.

[0019] Meanwhile, the inner support is two and in symmetrical state, forming a "V" state, and the corresponding outer support is also in "V" shape, and the inner support falls on the rubber main spring of the outer support; at this time, the inner support will not displace, and it is also ensured that the translational modal is less than 32 Hz, and the NVH problem risk can be solved.

[0020] The inner support and the lower support are assembled by the notch and the gap to form a lock, so that the position of the inner support and the lower support is relatively fixed, that is, the omnidirectional limiting of the whole radiator suspension cushion is realized; the inner support is provided with a recess and a notch, and the rubber main spring is formed on the outer wall and the inner wall of the recess and the notch and the corresponding gap by a vulcanization process, so that the bonding area of the rubber main spring and the inner support is large enough, and the risk of the rubber main spring falling off from the outer wall of the inner support is reduced.

[0021] The outer side of the rubber main spring abuts against the inner wall of the outer support, and the inner support and the lower support are vulcanized with rubber at the contact or bonding parts, so that the rubber main spring has omnidirectional limiting and shear resistance; by appropriately adjusting the local wall thickness of the rubber main spring, different stiffnesses can be obtained, so that different stiffness needs are met, and the whole radiator suspension cushion can provide better HNV.

[0022] In summary, the novel radiator suspension cushion provided by the patent has the advantages of light weight, low cost, high production efficiency, compact structure, simple and reliable installation, and can provide better HNV for vehicle models with different stiffness needs.
