Description

Technical Field

[0001] This utility model relates to the technical field of engine shock absorption components, and in particular to a longitudinally mounted engine mount assembly. Background Technology

[0002] With the continuous development of the automotive industry, people's demands for vehicle comfort and durability are increasing. In automotive design, the installation and mounting of the powertrain is a crucial aspect. The powertrain is fixed to the chassis via a suspension system. However, as the core component of the powertrain, the engine's size, weight, and performance indicators are constantly increasing. Simultaneously, the chassis structure and the layout of surrounding accessories impose certain limitations on the powertrain's installation space, leading to increasingly cramped installation design space. Under such limited space conditions, designing a reasonable assembly structure to meet the overall vehicle comfort and durability requirements under various complex operating conditions has become an important challenge in the automotive R&D field.

[0003] Currently, to improve automotive comfort and durability, the industry commonly employs relatively complex suspension structures. These complex suspension systems typically consist of numerous components, increasing production costs and placing higher demands on manufacturing processes. For example, some suspension systems require high-precision machining equipment and complex assembly processes to ensure their performance, undoubtedly increasing production costs and manufacturing difficulty. Furthermore, complex suspension structures are more inconvenient for later maintenance and repair, requiring specialized technicians to spend more time and effort, further increasing operating costs.

[0004] Given the high cost and complex manufacturing processes of existing automotive mounting systems, there is an urgent need in this field for a new technological solution that can overcome the limitations of traditional designs. This solution should be characterized by simple structure, low cost, and ease of manufacturing, while exhibiting excellent vibration reduction, isolation, and durability under various operating conditions. This would effectively meet the stringent requirements of modern automobiles for comfort and reliability, and drive the development of automotive mounting technology towards a more efficient and economical direction. Utility Model Content

[0005] Based on the technical problems existing in the background technology, this utility model proposes a longitudinal engine mount assembly, which has a simple structure, low cost, and is easy to manufacture. It also has excellent vibration reduction, vibration isolation, and durability under various working conditions.

[0006] To achieve the above objectives, the present invention provides a longitudinally mounted engine mount assembly, including a welded bracket, a lower bracket, an upper plate, and a rubber body. The lower bracket and the upper plate are connected by vulcanization of the rubber body to form a rubber main spring, which is installed in the internal space of the welded bracket. The end of the welded bracket is provided with a limiting block corresponding to the bent end of the lower bracket to limit the movement of the lower bracket.

[0007] Preferably, the bottom of the rubber main spring is provided with a bolt, which passes through the welding bracket and is connected to the nut.

[0008] Preferably, the upper plate of the lower bracket has a triangular structure with a rim, and the middle part is provided with a mounting hole for connecting to the engine.

[0009] Preferably, one side of the lower support is bent at 45° and the other side is bent at 90°.

[0010] Preferably, rubber is attached to both sides of the lower support to form anti-collision pads at the bends.

[0011] Preferably, the anti-collision pad is part of the rubber body and can buffer collisions during engine operation.

[0012] Preferably, the welding bracket extends on both sides to form mounting surfaces that fit against the vehicle body, and the mounting surfaces are provided with mounting holes for connecting to the vehicle body.

[0013] Preferably, the welding bracket is provided with limiting baffles on both sides and in the front and rear directions.

[0014] Preferably, the components are arranged on the frame at a 50° angle along the Z-axis.

[0015] Preferably, the surfaces of the welding bracket, the lower bracket, and the upper plate are all treated with electrophoretic paint for rust prevention, and the nut is treated with Dacromet coating.

[0016] In summary, this utility model has the following beneficial technical effects:

[0017] This invention utilizes a natural rubber body to vulcanize and connect the lower bracket and upper plate to form a rubber main spring, which is then cleverly installed inside the welded bracket. By leveraging the elastic properties of the rubber body, it effectively isolates and attenuates engine vibration, significantly reducing the transmission of vibration and noise generated during engine operation to the vehicle body. This greatly improves the overall ride comfort of the vehicle, creating a quieter and smoother driving environment for passengers and meeting the ever-increasing demands of modern automobiles for interior comfort.

[0018] The limiting block structure at the end of the welded bracket, along with the limiting baffles on its sides and in the front and rear directions, together form a comprehensive limiting system. This system effectively restricts engine displacement under various complex conditions, such as when the vehicle is driving on bumpy roads, or during rapid acceleration or deceleration. It prevents excessive engine displacement from damaging surrounding components or generating abnormal noise, enhancing the reliability and durability of the mounting assembly. This ensures stable vehicle performance over long-term use, while reducing maintenance costs and risks, thus providing strong support for the reliability and safety of the vehicle.

[0019] The welded bracket, lower bracket, and upper plate are treated with electrophoretic paint for rust prevention, and the nuts are treated with Dacromet coating, giving the entire suspension assembly excellent corrosion resistance. It meets the salt spray test requirement of 120 hours, enabling it to withstand the demands of automotive use in various harsh environments, such as high humidity and saline-alkali areas. This extends the service life of the suspension assembly, reduces the frequency of component replacement due to corrosion, and lowers maintenance and time costs for car owners. Furthermore, the suspension assembly has a simple and rational structural design with fewer components, facilitating manufacturing and assembly, reducing production costs, improving production efficiency, and making it easy to promote and apply to different vehicle models. It has good market application prospects and practical promotion value. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model discloses a longitudinally mounted engine mount assembly, such as... Figure 1 and Figure 2 As shown, it mainly consists of a welded bracket 1, a lower bracket 2, an upper plate 3, a nut 4, and a rubber body 5. The lower bracket 2 and the upper plate 3 are connected by vulcanization via the rubber body 5, forming a single, integral rubber spring (as shown). Figure 4 (As shown). After vulcanization, the rubber main spring is connected to the upper plate 3 by bolts, the mounting hole in the middle of the welded bracket 1 and the nut 4, thus forming a complete engine mount assembly.

[0029] In this embodiment, the rubber main spring, as the core vibration damping and noise reduction component, is installed in the internal space of the welding bracket 1. The end of the welding bracket 1 is specially designed with a limiting block structure corresponding to the lower bracket 2. When the lower bracket 2 is installed in place, the bent portion at the end of the lower bracket 2 is located directly below the limiting block, thereby limiting the lower bracket 2 in the vertical direction. Furthermore, the rubber body 5 is made of natural rubber through a vulcanization process, maintaining good physical properties and durability even under the high temperatures generated by engine operation, thus ensuring the comfort of the vehicle during use and the reliability of the overall system. Further, limiting baffles can be provided on both sides and in the front-rear direction of the welding bracket 1. This all-around limiting design allows the suspension assembly to exhibit excellent vibration damping performance and vibration isolation effect when facing various complex working conditions.

[0030] Regarding the material selection and processing technology of the welding bracket 1 and the lower bracket 2, both are made of QSTE650 material and formed through stamping and subsequent welding processes. The welding bracket 1 has a mounting hole in the middle for connecting with the upper plate 3, and mounting surfaces extending from both sides to fit the vehicle body. These mounting surfaces also have mounting holes for connecting with the vehicle body, ensuring the entire suspension assembly is securely mounted to the vehicle body. The upper plate of the lower bracket 2 is processed into a triangular structure with edging (e.g., ...). Figure 5 As shown), the lower bracket 2 has mounting holes in its middle for connecting to the engine. Specifically, one side of the lower bracket 2 is designed with a 45° bend, and the other side with a 90° bend, with rubber attached to both bends at the lower end to form a bumper pad (as shown). Figure 4As shown in the figure, the anti-collision pad is actually a component of the rubber body 5, which can play a role in buffering collisions during engine operation.

[0031] Two bolts are provided on the upper plate 3, and the positions of these two bolts precisely correspond to the mounting holes in the middle of the welding bracket 1 to ensure a reliable connection between the two. In actual installation applications, the engine mount assembly is arranged on the frame at a 50° angle along the left and right direction of the Z-axis (e.g., Figure 6 As shown in the figure, this arrangement helps to optimize the engine's support effect on the vehicle and its vibration damping performance.

[0032] In this embodiment, the surface treatment of the welded bracket 1, lower bracket 2, and upper plate 3 all employs electrophoretic paint anti-rust process to enhance their corrosion resistance in harsh environments. The nut 4 undergoes Dacromet treatment. After this surface treatment, the entire suspension assembly can withstand a salt spray test of 120 hours, thus meeting the stringent standards of the automotive industry for the corrosion resistance of components.

[0033] The longitudinally mounted engine mount assembly provided by this utility model has advantages such as simple and reasonable structural design, relatively low cost, and convenient manufacturing process. Through the ingenious cooperation and coordinated work of its various components, this mount assembly can effectively meet the vehicle's operating condition limit requirements in multiple directions, and maintain good shock absorption performance and durability under various operating conditions. This fully guarantees the vehicle's ride comfort and reliability requirements during driving, and has good market application prospects and practical promotion value.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
