Description

Technical Field

[0001] This utility model relates to the technical field of rubber-metal vibration damping components for vehicle chassis, and in particular to a mold for a quick-adjustment pressure relief valve structure. Background Technology

[0002] Automobiles are an indispensable means of transportation in modern society, and comfort remains a constant focus for both gasoline-powered and new energy vehicles. In the rubber-metal vibration damping components of vehicle chassis, hydraulic bushings are increasingly being adopted by major OEMs to provide better comfort. Compared to traditional automotive rubber bushings, hydraulic bushings have made significant progress in balancing softness and damping effect. While the exterior uses familiar rubber material, the interior features carefully arranged chambers and channels filled with damping fluid. During suspension movement, when the hydraulic bushing is compressed, the damping fluid quickly flows to the other side. This design allows the hydraulic bushing to maintain initial vibration damping softness while providing the necessary damping force at the end, effectively preventing unnecessary vibrations and thus providing the chassis with a soft yet resilient damping experience.

[0003] One type of hydraulic bushing contains a pressure relief valve. This device opens when the fluid in the chamber is insufficient to quickly flow into the other chamber through the flow channel, allowing the damping fluid to pass directly through the valve into the other chamber. This is designed to reduce the transmission of road impacts under complex road conditions. Because the bushing design requires frequent damping adjustments in the early stages to achieve the best vibration reduction effect, and because the pressure relief valve design also needs continuous optimization and adjustment if there are flaws, the pressure relief valve structure is constantly being modified.

[0004] Existing hydraulic bushing vulcanization molds are generally double-lobed structures. In order to achieve better vibration reduction, the pressure relief valve structure often needs to be replaced. The double-lobed molds need to be completely reprocessed, which is not conducive to quick production adjustment and has high replacement costs.

[0005] To address this, we propose a mold for quickly adjusting the structure of the pressure relief valve. Utility Model Content

[0006] In response to the shortcomings of the existing production technology, the applicant provides a mold for quickly adjusting the structure of a pressure relief valve. This allows for the formation of different pressure relief valves by quickly replacing different first and second small segments, as well as different fourth and fifth small segments, according to different hydraulic bushing performance requirements.

[0007] The technical solution adopted in this utility model is as follows:

[0009] First sub-lobes, second sub-lobes, third sub-lobes, fourth sub-lobes, fifth sub-lobes, sixth sub-lobes;

[0010] The first and second large segments are used to clamp and fix the first, second, third, fourth, fifth, and sixth small segments.

[0011] The first, second, third, fourth, fifth, and sixth small segments are arranged in a ring-shaped sequence; the first, second, fourth, and fifth small segments are respectively formed in the solid direction of the hydraulic bushing, and the third and sixth small segments are respectively formed in the hollow direction of the hydraulic bushing; at least one hydraulic valve forming structure is provided on the inner side of the first and second small segments and the inner side of the fourth and fifth small segments.

[0012] Its further features are:

[0013] The hydraulic valve forming structure inside the first and second small segments is the same as the hydraulic valve forming structure inside the fourth and fifth small segments.

[0014] The hydraulic valve forming structure inside the first and second small segments is different from the hydraulic valve forming structure inside the fourth and fifth small segments.

[0015] The first and second large segments are clamped and fixed together with bolts.

[0016] One side of the first small lobe contacts one side of the second small lobe, the other side of the first small lobe contacts one side of the sixth small lobe, the other side of the second small lobe contacts one side of the third small lobe, the other side of the third small lobe contacts one side of the fourth small lobe, the other side of the fourth small lobe contacts one side of the fifth small lobe, and the other side of the fifth small lobe contacts the other side of the sixth small lobe.

[0017] The first, second, third, fourth, fifth, and sixth sub-lobes form a ring shape.

[0018] The beneficial effects of this utility model are as follows:

According to different hydraulic bushing performance requirements, different first and second small segments, different fourth and fifth small segments can be quickly replaced.
