Engine front suspension

Abstract

An engine front mount includes an inner frame, a suspension rubber body, a base, a right-side frame, and a left-side frame. The main cross-section of the inner frame is an inverted isosceles trapezoid, and each side of the inner frame is connected to the right-side and left-side frames via the suspension rubber body. The right-side and left-side frames are symmetrically arranged. The inner frame, suspension rubber body, right-side frame, and left-side frame are integrally formed through a rubber vulcanization process. The right-side and left-side frames are bent outward to form side frame bending plates, and each side frame bending plate is tightly connected to the base mounting surface of the base. This utility model, through optimized structural design, ensures that the stress on the base is still less than the yield strength of the material. Combined with fatigue test results, under a loading condition of ±3g, it can withstand 1 million vibrations without any damage. This new base is superior to traditional composite mounts in terms of service life and strength.

Description

Technical Field

[0001] This utility model relates to a front mount, specifically an engine front mount. Background Technology

[0002] In fields such as machinery and equipment manufacturing and the automotive industry, composite suspension bases serve as key components for support and vibration damping, and their performance directly affects the operational stability and reliability of equipment. However, existing composite suspension bases suffer from numerous production cost issues.

[0003] From a structural design perspective, traditional suspension bases often employ complex, integrated structures. The excessive number of components not only increases manufacturing difficulty but also leads to excessive material consumption during production, thus driving up costs. For example, some bases, to achieve multiple functional integrations, incorporate numerous reinforcing ribs and connecting bosses. These structures require multiple complex processing steps in actual production, resulting in high manufacturing costs. Regarding material selection, many manufacturers, in order to ensure the strength and durability of the suspension base, blindly choose high-performance, high-cost metals or special composite materials without fully considering the actual operating conditions' requirements for material performance. This excessive material selection leads to material costs far exceeding actual needs, causing unnecessary waste. Furthermore, the poor machinability of some materials further increases manufacturing costs. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a front engine mount.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: an engine front mount, comprising an inner frame, a suspension rubber body, a base, a right frame, and a left frame. The main cross-section of the inner frame is an inverted isosceles trapezoidal structure, and each side of the inner frame is connected to the right frame and the left frame through the suspension rubber body. The right frame and the left frame are symmetrically arranged. The inner frame, the suspension rubber body, the right frame, and the left frame are integrally formed by a rubber vulcanization process. The right frame and the left frame are bent outward to form side frame bending plates, and each side frame bending plate is tightly connected to the base mounting surface of the base.

[0006] Furthermore, the left and right sides of the back of the base are provided with base side limiting surfaces, the bottom of the back of the base is provided with an upwardly recessed lower limiting surface, and the top of the back of the base is provided with a downwardly recessed upper limiting surface.

[0007] Furthermore, the outer edge of the back of the base is provided with multiple mounting holes for fixed connection with the frame. The inner frame is designed with mounting threads and positioning pins for fixed connection with the engine mount. Positioning pins are optional to ensure smooth connection between the engine, suspension, and body.

[0008] Furthermore, the base edge between the right and left skeletons is recessed inward, separating the lower ends of the right and left skeletons from each other.

[0009] Furthermore, the mounting holes extend outwards, and the outer walls between the mounting holes are reinforced with reinforcing ribs.

[0010] Furthermore, the two sides of the base protrude outwards.

[0011] The weight of this utility model is approximately 8.4 kg, which is about 0.5 kg less than the traditional fully enclosed suspension. At the same time, because all the limiting structures of the product are retained, the movement trajectory of the vulcanized body in the base is still within the controllable range. This invention utilizes CAE finite element analysis to optimize the structural design. The inner skeleton, suspension rubber body, right side skeleton, and left side skeleton are integrally formed through a rubber vulcanization process. The right side skeleton and left side skeleton are bent outward to form side skeleton bending plates, and each side skeleton bending plate is tightly connected to the base mounting surface of the base, ensuring that the stress on the base is still less than the yield strength of the material. Combined with fatigue test results, under a loading condition of ±3g, it can withstand 1 million vibrations without any damage. This new type of base is superior to traditional composite suspension in terms of service life and strength. Attached Figure Description

[0012] The present invention will now be further described with reference to the accompanying drawings.

[0014] like Figure 1-2 As shown, an engine front mount includes an inner frame 1, a mounting rubber body 2, a base 3, a right frame 4, and a left frame 5. The main cross-section of the inner frame 1 is an inverted isosceles trapezoidal structure, and each side of the inner frame 1 is connected to the right frame 4 and the left frame 5 through the mounting rubber body 2. The right frame 4 and the left frame 5 are symmetrically arranged. The inner frame 1, the mounting rubber body 2, the right frame 4, and the left frame 5 are integrally formed by a rubber vulcanization process. The right frame 4 and the left frame 5 are bent outward to form side frame bending plates 6, and each side frame bending plate 6 is tightly connected to the base mounting surface 7 of the base 3.

[0015] Specifically: The left and right sides of the back of the base 3 are provided with base side limiting surfaces 8, the bottom of the back of the base 3 is provided with an upwardly recessed lower limiting surface 9, the top of the back of the base 3 is provided with a downwardly recessed upper limiting surface 10, and the outer edge of the back of the base 3 is provided with multiple mounting holes 11.

[0016] The base 3 between the right frame 4 and the left frame 5 is recessed inward, so that the lower ends of the right frame 4 and the left frame 5 are separated from each other. The mounting hole 11 extends outward, and the outer walls between the mounting holes 11 are reinforced by reinforcing ribs 12. The two sides of the base 3 protrude outward.

[0017] The base can be fixedly connected to the frame through mounting holes. The inner frame is designed with mounting threads and positioning pins, which can be fixedly connected to the engine mount. Positioning pins are optional, ensuring a smooth connection between the engine, suspension, and body.

[0018] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
