Description

Technical Field

[0001] This utility model relates to the field of flywheel housing technology, and in particular to a lightweight flywheel housing. Background Technology

[0002] The flywheel housing is a key connecting component between the engine and the transmission, primarily used to enclose the flywheel assembly and support peripheral components such as the crankcase and starter. Its basic structure includes a through-hole crankshaft and a flywheel mounting cavity; some models integrate a gear chamber for mounting auxiliary equipment such as the oil pump and compressor.

[0003] For example, CN209245588U discloses a flywheel housing, a flywheel housing body, and a steering pump mounting hole. The back of the flywheel housing body has a gear system mounting cavity; and the steering pump mounting hole is opened on the shoulder of the front of the flywheel housing body, and the steering pump mounting hole is used for mounting and fixing the steering pump; wherein, the crankshaft gear, idler gear, steering pump drive gear, and steering pump gear are mounted in the gear system mounting cavity.

[0004] However, in the existing technology, the excessive weight of the flywheel housing leads to an increase in the overall energy consumption of the equipment, and generates a large inertial force when running at high speed, which affects the service life of the equipment. The unreasonable weight reduction design and excessive weight reduction result in insufficient strength of the support structure, which cannot reliably support the flywheel and poses a safety hazard. Utility Model Content

[0005] The purpose of this invention is to solve the problems of excessive flywheel housing weight in the prior art, which leads to increased overall energy consumption of the equipment and generates large inertial forces during high-speed operation, affecting the service life of the equipment. Therefore, a lightweight flywheel housing is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight flywheel housing, comprising a housing, a side plate fixedly connected to the side wall of the housing, a support ring fixedly connected to the inner side of the housing, a plurality of second weight-reducing holes being opened on the outer surface of the support ring, the plurality of second weight-reducing holes being evenly distributed on the outer surface of the support ring, and an inner ring fixedly connected to the inner side of the support ring, a plurality of support rods being symmetrically fixedly connected to the inner side of the inner ring, a fixing ring being fixedly connected to the inner side of each of the plurality of support rods, and the inner wall of the support ring being fixedly connected to the side plate, and a plurality of weight-reducing grooves being opened on the outer edge of the support ring.

[0007] Preferably, a bushing is fixedly connected to the middle of the side plate, and a connecting groove is provided in the middle of the side plate.

[0008] Preferably, multiple support blocks are fixedly connected to the outer surface of the housing.

[0009] Preferably, a reinforcing ring is provided on the outer side of the shell, and the inner wall of the reinforcing ring is fixedly connected to multiple support blocks.

[0010] Preferably, a bottom block is fixedly connected to the center of the bottom of the shell.

[0011] Preferably, the outer side of the shell has multiple first weight-reduction holes.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, during the flywheel installation process, the support ring not only provides the necessary support force, but also reduces its own material consumption and overall weight through the weight reduction holes and weight reduction grooves, while ensuring the support function and structural stability. The weight reduction holes effectively reduce the weight burden, while the weight reduction grooves further enhance the lightweight effect, ensuring the stability of the flywheel and the efficiency of energy transfer. During the connection process between the flywheel and the support ring, the bushing design ensures a reliable connection between the flywheel and the shaft end. The fixed ring securely fixes the shaft end, avoiding loosening or instability. The fixed ring and bushing together provide a protection mechanism, ensuring the smooth progress of the flywheel installation process.

[0014] 2. In this utility model, by using support blocks and support rings as the main reinforcement means, the arrangement of these components effectively enhances the robustness of the shell and limits the deformation and displacement of the shell when subjected to external pressure. The combination of support blocks and support rings forms multiple support points through reasonable cooperation, evenly distributing external forces and avoiding damage caused by excessive local load. In order to optimize the design and ensure smooth connection with other components, the bottom block provides a stable access platform to ensure stable connection between the shell and other components. Considering the impact of weight on performance, the design of the weight reduction hole further optimizes the mass of the shell, reducing the overall weight of the shell without affecting the structural strength and support function, and improving the flexibility and convenience of the equipment.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a lightweight flywheel housing, including a housing 1, a side plate 3 fixedly connected to the side wall of the housing 1, a support ring 2 fixedly connected to the inner side of the housing 1, a plurality of second weight-reducing holes 21 opened on the outer surface of the support ring 2, the plurality of second weight-reducing holes 21 being evenly distributed on the outer surface of the support ring 2, and an inner ring 23 fixedly connected to the inner side of the support ring 2, a plurality of support rods 24 being symmetrically fixedly connected to the inner side of the inner ring 23, a fixing ring 25 being fixedly connected to the inner side of each of the plurality of support rods 24, and the inner wall of the support ring 2 being fixedly connected to the side plate 3, and a plurality of weight-reducing grooves 22 being opened on the outer edge of the support ring 2.

[0023] The specific settings and functions of this embodiment will be described in detail below. During the flywheel installation process, the support ring 2 not only provides the support force required for flywheel installation, but its design also takes into account the needs of weight reduction and lightweighting to achieve performance optimization. Through the ingenious weight-reduction structure design, the support ring 2 effectively reduces the weight of the entire device without sacrificing the structural stability and the reliability of the flywheel support.

[0024] First, the presence of the second weight-reducing hole 21 primarily aims to reduce the material consumption of the support ring 2 itself, thereby lowering its overall weight. This not only effectively reduces unnecessary mass burden but also optimizes weight distribution without affecting its support function. Furthermore, the addition of the weight-reducing groove 22 further enhances the lightweighting effect. While maintaining structural strength, it minimizes the weight of the support ring 2, enabling more efficient energy transfer without compromising flywheel stability.

[0025] During the connection between the flywheel and the support ring 2, the design of the bushing 31 ensures a reliable connection between the flywheel and the shaft end. The engagement of the bushing 31 with the connecting end, secured by the retaining ring 25, effectively prevents loosening or instability that may occur during installation. The retaining ring 25 and the bushing 31 together form a protective mechanism, ensuring the smooth installation of the flywheel and providing stable support for the entire connection. Through this structural optimization, flywheel installation is not only more convenient but also significantly improves the stability and safety of the entire system.

[0026] Example 2: Figure 2 - Figure 4 As shown, a bushing 31 is fixedly connected to the middle of the side plate 3, and a connecting groove 32 is provided in the middle of the side plate 3. Multiple support blocks 12 are fixedly connected to the outer surface of the housing 1. A reinforcing ring 11 is provided on the outer side of the housing 1, and the inner wall of the reinforcing ring 11 is fixedly connected to the multiple support blocks 12. A bottom block 14 is fixedly connected to the center of the bottom of the housing 1. Multiple first weight-reducing holes 13 are provided on the outer side of the housing 1.

[0027] The overall effect of this embodiment is that, in order to ensure the structural strength and stability of the shell 1, support blocks 12 and reinforcing rings 11 are used as the main reinforcement methods. The arrangement of these components not only effectively enhances the overall robustness of the shell 1, but also effectively limits the deformation and displacement of the shell 1 under external pressure. The combination of support blocks 12 and reinforcing rings 11, through a reasonable matching method, forms multiple support points within the shell 1, thereby evenly distributing external forces and avoiding structural damage caused by excessive load on a single point.

[0028] In addition, to further optimize the design of housing 1 and ensure its smooth connection with other mechanical components, base block 14 provides a stable access platform, enabling housing 1 to be easily and stably connected and installed with other components.

[0029] Considering the impact of weight on the overall performance of the device, the design of the first weight-reducing hole 13 further optimizes the mass of the housing 1. While ensuring structural strength and support function, the weight-reducing hole effectively reduces the overall weight of the housing 1, minimizing unnecessary burdens caused by excessive weight. The weight-reducing hole not only makes the housing 1 lighter but also enhances the flexibility and convenience of the equipment during use.

[0030] The shell 1, through the joint action of the support block 12 and the reinforcing ring 11, ensures its stability when bearing external loads. At the same time, the bottom block 14 provides a simple and solid foundation for connection, and the weight reduction hole optimizes the overall weight. The design of the shell 1 achieves reasonable weight control while providing necessary protection and support, avoiding inconvenience and additional energy consumption caused by excessive weight.

[0031] The device's usage and working principle are as follows: The flywheel can be easily installed via the support ring 2. During this process, the second weight-reducing hole 21 reduces weight, while the weight-reducing groove 22 further reduces the weight of the support ring 2, thus achieving weight reduction while stably supporting the flywheel. Furthermore, during flywheel connection, the use of the bushing 31 provides double protection to the connecting end of the shaft during flywheel installation, thanks to both the fixing ring 25 and the bushing 31, ensuring connection stability.

[0032] To ensure overall stability, the housing 1 is reinforced by the support blocks 12 and reinforcing rings 11, ensuring the overall structure is stable. Meanwhile, the base block 14 facilitates connection and installation, and the design of the first weight-reducing hole 13 reduces the overall weight of the housing 1, allowing it to protect and support the flywheel while avoiding excessive weight.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
