Description

Technical Field

[0001] This utility model relates to the field of engine technology, and in particular to a multifunctional bracket for an engine. Background Technology

[0002] The engine is the core power unit of modern industry, and its performance and reliability directly affect the overall operating efficiency of the machine. In the engine system, various auxiliary components (such as air conditioning compressor, fuel injection pump, pulley chamber, idler pulley, pipeline, wiring harness and lifting lugs, etc.) need to be fixed to the engine body by special brackets.

[0003] Currently, most common engine mounts are single-function designs, with each mount used to secure only a specific component. These mounts are typically made of sheet metal stampings or cast iron. Sheet metal mounts have a simple structure but lack rigidity and are prone to vibration; cast iron mounts, while strong enough, are heavy, which runs counter to the current trend of lightweight and fuel-efficient engine development.

[0004] In addition, some engine mounts attempt to integrate multiple functions, but their integration level is generally low, usually only able to integrate and fix two or three components, failing to fundamentally reduce the total number and weight of the mounts. Moreover, these integrated mounts are mostly made of cast iron, resulting in poor weight reduction, and the complex stress conditions brought about by the integration of multiple components place higher demands on their structural design. Improper design can easily lead to problems such as resonance or insufficient strength, resulting in decreased reliability.

[0005] Therefore, existing engine mount technologies suffer from drawbacks such as limited functionality, low integration, heavy overall weight, and difficulty in achieving both high reliability due to material and design limitations. There is an urgent need for a highly integrated, lightweight, and structurally robust solution to simplify engine compartment layout and reduce overall weight and manufacturing costs.

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0007] Therefore, to solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-functional bracket for an engine, comprising a bracket body; the bracket body integrates:

[0008] Engine mounting section, used for connection to the engine body;

[0009] Air conditioner installation section, used to fix air conditioner components;

[0010] Fuel injection pump mounting section, used for fuel injection pump gear timing and fixing the fuel injection pump;

[0011] Pulley chamber mounting section, used to fix the pulley chamber;

[0012] Multi-wheel mounting section, used to fix the idler wheel;

[0013] Pipeline or wire harness mounting holes are used to secure pipelines or wire harnesses.

[0014] The lifting lug mounting part includes lifting lug mounting holes for fixing the engine lifting lug.

[0015] As a preferred embodiment of the multifunctional bracket on the engine described in this utility model, the engine mounting part is provided with a mounting surface adapted to the engine body, and an engine through hole is opened on the mounting surface. The engine body is fixed and connected to the engine mounting part through the engine through hole.

[0016] As a preferred embodiment of the multi-functional bracket on the engine described in this utility model, the air conditioning mounting part includes an air conditioning mounting groove adapted to the structure of the air conditioning component, and an air conditioning mounting hole for fixing the air conditioning component, wherein the air conditioning component is embedded in the air conditioning mounting groove through the air conditioning mounting hole.

[0017] As a preferred embodiment of the multi-functional bracket on the engine described in this utility model, the fuel injection pump mounting part includes a timing hole for realizing the timing of the fuel injection pump gear, and a fuel injection pump mounting hole for fixing the fuel injection pump body.

[0018] As a preferred embodiment of the multi-functional bracket on the engine described in this utility model, the pulley chamber mounting part is provided with pulley chamber mounting holes for fixing the pulley chamber, and the pulley chamber mounting holes are distributed in the support area of ​​the pulley chamber.

[0019] As a preferred embodiment of the multi-functional bracket on the engine described in this utility model, the multi-wheel mounting part is provided with a large idler wheel mounting hole and a small idler wheel mounting hole. The large idler wheel mounting hole is used to fix the large idler wheel, and the small idler wheel mounting hole is used to fix the small idler wheel.

[0020] As a preferred embodiment of the multi-functional bracket on the engine described in this utility model, the main body of the bracket is an integrally cast aluminum alloy bracket, including a main bearing plate, and a first side enclosure and a second side enclosure disposed on the front and rear wall edges of the main bearing plate.

[0021] The first side enclosure is arranged around the outer periphery of the fuel injection pump gear;

[0022] The air conditioner installation unit is located in the lower area of ​​the second side enclosure.

[0023] As a preferred embodiment of the multi-functional bracket on the engine described in this utility model, the second side enclosure is provided with a weight reduction groove, and the weight reduction groove is provided with transverse reinforcing ribs and longitudinal reinforcing ribs distributed in a grid pattern. The junction of the transverse reinforcing ribs and the longitudinal reinforcing ribs and the connection with the bracket body are provided with reinforcing skirts.

[0024] The beneficial effects of this utility model are:

[0025] 1. This utility model integrates seven major functions—engine mounting, air conditioning component fixing, fuel injection pump fixing, timing, pulley chamber fixing, large and small idler pulley fixing, pipeline / wiring harness fixing, and lifting lug mounting—into a single molded bracket body. This greatly simplifies the layout of the engine side, reduces the number of parts and assembly steps, avoids spatial interference and cumulative error problems caused by multiple bracket installations, and improves assembly efficiency and precision.

[0026] 2. This utility model abandons traditional cast iron materials and adopts high-strength aluminum alloy die casting, achieving weight reduction from the fundamental material aspect. By opening weight-reducing grooves in the side enclosure area and arranging grid-like reinforcing ribs and reinforcing skirts within the grooves, an advanced structure of "hollowed-out weight reduction + rib reinforcement" is formed. While ensuring that the overall rigidity and strength far exceed the design requirements, the bracket is successfully made lightweight, effectively contributing to the overall weight reduction of the engine.

[0027] 3. The support structure of this utility model has superior dynamic and static performance. Its high first-order natural frequency effectively avoids the normal operating excitation frequency of the engine, preventing resonance, reducing noise, and improving component life. The optimized stress distribution ensures that even under extreme loads, the stress is far below the allowable value of the material, guaranteeing the operational safety and reliability of the support and the valuable components (such as the fuel injection pump) mounted on it.

[0028] 4. The integrated design of this utility model eliminates the material and processing costs of multiple independent cast iron supports, thus optimizing the total material cost.

[0029] 5. This utility model integrates the fuel injection pump timing function into the bracket body. Through a built-in positioning sleeve structure (positioning groove and positioning pin hole), it ensures the precise setting and fixation of the relative phase (40° before top dead center) between the fuel injection pump gear and the engine shaft. This structure simplifies the originally complex assembly process, allowing for quick and accurate positioning via the positioning pin. It effectively prevents gear rotation during belt tensioning, ensuring the accuracy of the engine's fuel injection timing and thus improving engine performance. Attached Figure Description
