[0002] The heavy-duty truck engine suspension cushion is one of the important components that must be used in heavy-duty truck engines. Its main function is to reduce the transmission of engine vibration to the frame and enhance the comfort of the whole vehicle. The main principle of the suspension cushion vibration reduction is to convert mechanical energy into heat energy and release it through the characteristics of rubber. The design of the heavy-duty truck engine suspension cushion has a great influence on the NVH performance of the whole vehicle. The heavy-duty truck engine suspension cushion is a component installed between the engine and the frame. As a component in the engine suspension system, it plays a very important role in the engine suspension system. The existing heavy-duty truck engine suspension cushion also has a good seismic isolation effect, but its structure and manufacturing process are relatively complex, and generally require assembly, which increases the manufacturing cost of the heavy-duty truck engine rear suspension cushion, and due to its large size, it will occupy a large engine compartment space when installed to connect the engine and the frame. Therefore, it is necessary to improve the existing heavy-duty truck engine suspension cushion. [Contents of the utility model]
[0003] The purpose of the utility model is to solve the problems in the prior art and to propose an improved suspension cushion for a heavy truck engine, which can simplify the suspension cushion structure, reduce the production difficulty and cost, and improve the production efficiency. Moreover, since no assembly is required, the rear suspension cushion will not fail due to looseness of the assembly part during use.
[0004] To achieve the above-mentioned purpose, the utility model proposes an improved suspension cushion for a heavy-duty truck engine, comprising a fixing plate, an outer support sleeve, and an inner support core. The fixing plate is vertically arranged, and a plurality of first mounting holes are opened on the fixing plate. An outer support sleeve is fixed to one side of the fixing plate, and an inner support core is arranged inside the outer support sleeve. The inner support core includes a supporting surface, which is located outside the outer support sleeve. The supporting surface is a horizontal plane, and a plurality of second mounting holes are opened on the supporting surface. The inner wall of the outer support sleeve and the outer wall of the inner support core are fixed to each other by a vulcanized one-piece molded rubber pad.
[0005] Preferably, the outer support sleeve is perpendicular to the fixed plate, the outer support sleeve is in a convex hexagon, and the top wall and the bottom wall of the outer support sleeve are both horizontal plates.
[0006] Preferably, the inner support core is composed of a support plate, a first plate body, a second plate body, and a third plate body. The combination of the first plate body, the second plate body and the third plate body is formed by bending a plate as a whole. The support plate, the first plate body, the second plate body and the third plate body form a trapezoidal hollow structure. The support plate is located at the top end of the inner support core, the support plate is horizontally arranged, and a part of the support plate is located outside the inner support core. The support surface is a part of the upper end surface of the support plate, the second mounting hole passes through the support plate, the third plate body is located below the support plate, the third plate body is parallel to the support plate, and the first plate body and the second plate body are both parallel to the adjacent side walls of the outer support sleeve.
[0007] Preferably, the rubber pad is fixed to the fixing plate by vulcanization.
[0008] Preferably, there is a gap between the inner support core and the fixing plate.
[0009] Preferably, a plurality of heat dissipation protrusions are provided on the side of the rubber pad away from the fixing plate.
[0010] Preferably, a plurality of reinforcing ribs are provided on the outer wall of the outer support sleeve, and the reinforcing ribs are fixed to the fixing plate.
[0011] The beneficial effects of the utility model are as follows: the utility model fixes the inner wall of the outer support sleeve and the outer wall of the inner support core by means of a vulcanized one-piece rubber pad, thereby making the structure of the engine suspension cushion simpler, requiring no assembly, and preventing the suspension cushion from failing due to loosening of the assembly part during use, making the use of the utility model more reliable.
[0012] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.
