Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] The core of the utility model is to provide a high-strength and lightweight flywheel housing, which has high strength and light weight.
[0028] Please refer to Figures 1 to 4 A high-strength and lightweight flywheel housing includes a flywheel housing body 1. Specifically, the front of the flywheel housing body 1 is a flywheel chamber, and the back of the flywheel housing body 1 is a gear chamber. The flywheel housing body 1 is provided with a steering pump mounting hole 2, a gear mounting hole 3 and a center hole 4 to install a steering pump and a gear. The steering pump mounting hole 2 and the gear mounting hole 3 are both arranged near the top of the flywheel housing body 1, and the center hole 4 is arranged at the center of the flywheel housing body 1. The gear chamber is provided with a starter mounting hole 5 and a fuel pump mounting hole 6 to install a starter and a fuel pump. The starter mounting hole 5 and the fuel pump mounting hole 6 are both arranged near the bottom of the gear chamber. The gear chamber and the flywheel chamber are both provided with a reinforcement structure. The strength of the flywheel housing body 1 is increased by arranging the reinforcement structure. Weight reduction holes 7 are provided on both sides of the flywheel housing body 1 to make the flywheel housing body 1 more lightweight. A sewage discharge hole 8 is provided at the bottom of the flywheel housing body 1, which can effectively solve the problem of cleaning impurities in the flywheel chamber.
[0029] Among them, the bottom of the flywheel housing body 1 is provided with a drain hole 8. When the vehicle is running, the friction of the clutch plate will produce impurities and dust will appear during driving. The drain hole 8 at the bottom of the flywheel housing body 1 can effectively solve the impurity problem. In this embodiment, it is set in this way, but in real life, there is no limitation to this, as long as the above technical effect can be achieved.
[0030] The high-strength and lightweight flywheel housing arranged in the above manner has high strength and light weight, and can improve the performance of the vehicle.
[0031] In the above embodiment, the reinforcement structure of the flywheel chamber includes the first reinforcement rib 9 , which is arranged in the circumferential direction of the center hole 4 and extends in the radial direction of the center hole 4 .
[0032] It should be noted that the first reinforcing ribs 9 are distributed in a circle with the central hole 4 as the center, and play a role in reinforcing the flywheel housing body 1. In this embodiment, the first reinforcing ribs 9 are arranged in this way, but in real life, there is no limitation to this, as long as the above technical effect can be achieved.
[0033] In the above case, at least part of the first reinforcing ribs 9 extend to the flywheel housing body 1 along the radial direction of the central hole 4 .
[0034] It can be understood that there are multiple first reinforcing ribs 9, some of which extend directly along the radial direction of the center hole 4 to the flywheel housing body 1, connecting the center hole 4 and the flywheel housing body 1, thereby achieving a reinforcing effect.
[0035] Furthermore, a plurality of bolt mounting holes 10 are provided in the flywheel chamber, and the plurality of bolt mounting holes 10 are connected to the central hole 4 through corresponding first reinforcing ribs 9 .
[0036] It should be noted that another portion of the first reinforcing ribs 9 extends along the radial direction of the center hole 4 to the bolt mounting holes 10 , and is connected in a ring with the bolt mounting holes 10 , thereby playing a reinforcing role.
[0037] In the above embodiment, the reinforcement structure of the flywheel housing further includes a second reinforcement rib 11 . The second reinforcement rib 11 is a T-shaped structure. The second reinforcement rib 11 is used to connect the bolt mounting hole 10 and the flywheel housing body 1 .
[0038] It can be understood that the second reinforcing rib 11 is connected to the bolt mounting hole 10 and the flywheel housing body 1 in a T-shape, and is thus combined with the first reinforcing rib 9 to form an integral unit, which can effectively enhance the strength of the flywheel housing body 1 .
[0039] Among them, in this embodiment, the first reinforcing rib 9 and the second reinforcing rib 11 are arranged in this way, but in actual life, there is no limitation to this, as long as the above technical effect can be achieved.
[0040] On the basis of the above embodiment, the reinforcement structure of the gear chamber includes third reinforcement ribs 12 . The third reinforcement ribs 12 are distributed in a fan shape. The third reinforcement ribs 12 are used to connect the center hole 4 and the flywheel housing body 1 .
[0041] It should be noted that the fan-shaped structure formed by the third reinforcing ribs 12 of the gear chamber is integrally formed to increase the strength of the flywheel housing body 1 .
[0042] In the above embodiment, the reinforcement structure of the gear chamber further includes a fourth reinforcement rib 13 . The fourth reinforcement rib 13 is circular with an opening. The fourth reinforcement rib 13 is arranged in the circumferential direction of the center hole 4 .
[0043] It can be understood that the gear chamber is composed of a series of third reinforcing ribs 12 forming a fan-shaped structure. When the engine is running, the center hole 4 is subjected to greater force. The fourth reinforcing rib 13 is integrally formed with the flywheel housing body 1, which greatly enhances the strength of the flywheel housing body 1, thereby improving the overall crack resistance of the heavy-duty truck flywheel housing and ensuring the durability of the heavy-duty truck flywheel housing.
[0044] Among them, in this embodiment, the third reinforcing rib 12 and the fourth reinforcing rib 13 are arranged in this way, but in actual life, there is no limitation to this, as long as the above technical effect can be achieved.
[0045] As a preferred implementation, fifth reinforcing ribs 14 are provided on both sides of the flywheel housing body 1 , and the fifth reinforcing ribs 14 are cross-connected with the weight-reducing holes 7 .
[0046] It should be noted that the two sides of the flywheel housing body 1 are composed of weight-reducing holes 7 and fifth reinforcing ribs 14. The distribution of the weight-reducing holes 7 effectively reduces the weight of the flywheel housing body 1, making the product lightweight. The staggered fifth reinforcing ribs 14 are connected to ensure weight reduction while obtaining higher strength. If the connection of the fifth reinforcing ribs 14 is missing, the strength of the flywheel housing body 1 is reduced, and the vibration generated by the bracket during movement will cause the flywheel housing to crack, affecting the operation of the engine.
[0047] In the above case, the top surface of the flywheel housing body 1 is provided with a sixth reinforcing rib 15, the sixth reinforcing rib 15 is a diagonal structure, and the sixth reinforcing rib 15 is used to connect the top surface of the flywheel housing body 1 and the flywheel chamber.
[0048] It can be understood that the top end surface of the flywheel housing body 1 is integrated with the flywheel housing body 1 by the sixth reinforcing rib 15 in an oblique manner, thereby reinforcing the flywheel housing.
[0049] Among them, in this embodiment, the fifth reinforcing rib 14 and the sixth reinforcing rib 15 are arranged in this way, but in actual life, there is no limitation to this, as long as the above-mentioned technical effect can be achieved.
[0050] In summary, the high-strength and lightweight flywheel housing provided by the utility model is currently required to be lightweight while meeting the increasingly stringent emission and high explosion pressure requirements of heavy-duty tractor engines. In order to meet customer needs and achieve higher cost-effectiveness, the requirements for engine weight are more stringent. While meeting emission requirements, the engine pursues higher performance and reasonably reduces the weight of the engine. This application designs a high-strength and lightweight flywheel housing with high strength, light weight, easy manufacturing, long service life, and greatly improves the lightweight and durability of the engine to improve the performance of the vehicle.
[0051] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
[0052] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0053] The above is a detailed introduction to a high-strength and lightweight flywheel housing provided by the utility model. This article uses specific examples to illustrate the principles and implementation methods of the utility model. The description of the above embodiments is only used to help understand the method and core idea of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
