Description

Technical Field

[0001] The utility model mainly relates to the technical field related to engine flywheel housings, in particular to a flywheel housing. Background Art

[0002] The engine structure includes a flywheel, which is mainly used to store part of the energy of the engine's power stroke. The flywheel is mainly installed in a corresponding flywheel housing. In the prior art, the structures of flywheel housings are diverse, but most of them still use old structural designs, and there are few innovative structural designs. With the gradual improvement of engine technology, the actual products of old flywheel housings often contain some redundant parts that have no practical use, making the overall volume and weight of the flywheel housing large. In actual use, the flywheel housing often needs to be installed with corresponding components such as air filters and sensors. The existing air filter bracket generally adopts a two-point braid bridge connection method. When the engine is running, the air filter vibrates greatly and is easily damaged. In addition, the installation position design of the air filter and sensor is not reasonable, which is not conducive to the assembly of the product and the subsequent replacement and maintenance of accessories.

[0023] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model.

[0024] This embodiment provides a flywheel housing, and its related structure refers to Figure 1 , Figure 2 as well as Figure 3 shown.

[0025] The main structure of the flywheel housing of this embodiment is as follows: it includes a circular outer shell body 1, the inner part of the outer shell body 1 has a cavity, and a first machine foot mounting platform 2 and a second machine foot mounting platform 3 are respectively arranged on both sides of the lower part of the outer shell body 1, and the first machine foot mounting platform 2 and the second machine foot mounting platform 3 are respectively used to connect the engine foot.

[0026] In a specific implementation manner provided in this embodiment, the specific structures of the first machine foot mounting platform 2 and the second machine foot mounting platform 3 are as follows: the first machine foot mounting platform 2 and the second machine foot mounting platform 3 both protrude from the outer shell body 1, and the outer side surfaces of the first machine foot mounting platform 2 and the second machine foot mounting platform 3 are both flat, and are both provided with multiple machine foot threaded holes 9, which can be conveniently connected to the engine.

[0027] Among them, the first machine foot mounting platform 2 is a solid structure, the second machine foot mounting platform 3 is a hollow structure, the interior of the second machine foot mounting platform 3 is connected to the cavity of the shell body 1, and the second machine foot mounting platform 3 is provided with a starter motor mounting hole 7 for mounting the starter motor on the side away from the cavity opening of the shell body 1, and the starter motor mounting hole 7 is connected to the cavity of the shell body 1. In the above structure, not only can the installation of the starter motor be facilitated, but also the specific structure of the machine foot mounting platform is limited according to the force conditions, so as to ensure the structural strength and achieve lightweight design.

[0028] In this embodiment, an air filter mounting platform 4 is arranged in the middle of the top of the shell body 1. The air filter mounting platform 4 is mainly used for mounting the air filter. Designing it in the middle of the top of the shell body 1 can facilitate the installation and subsequent maintenance of the air filter.

[0029] In a specific implementation provided in this embodiment, the air filter mounting platform 4 abandons the traditional two-point bridge installation method and adopts a direct connection structure. As shown in the figure, the air filter mounting platform 4 protrudes from the shell body 1, the upper surface of the air filter mounting platform 4 is a plane, and is provided with a plurality of filter threaded holes 8. The air filter mounting platform 4 is designed as a hollow structure inside, which can ensure strength while being lightweight. The air filter can be directly connected to the air filter mounting platform 4 in the middle of the top of the shell body 1 through the filter threaded holes 8. By adopting the direct connection method in the middle of the top of the shell, the air filter is more convenient and firm to install, and the vibration of the air filter is smaller when the engine is running, and it is not easy to be damaged.

[0030] In this embodiment, a flywheel speed sensor mounting platform 5 is provided between the air filter mounting platform 4 and the second machine foot mounting platform 3, and is mainly used for mounting a flywheel speed sensor.

[0031] In a specific implementation provided by this embodiment, as shown in the reference figure, the flywheel speed sensor mounting platform 5 protrudes from the housing body 1, and two are arranged in parallel, on which a sensor threaded hole 10 is arranged, and the sensor threaded hole 10 penetrates the housing body 1, and is used to install the flywheel speed sensor, so as to facilitate the sensor to measure the flywheel speed. In this embodiment, the flywheel speed sensor mounting platform 5 is arranged in the middle position between the air filter mounting platform 4 and the second machine foot mounting platform 3, which is more conducive to the later installation and adjustment.

[0032] In this embodiment, a flywheel line observation port 6 is arranged between the flywheel speed sensor mounting platform 5 and the second machine foot mounting platform 3. The flywheel line observation port 6 is connected to the cavity of the outer shell body 1. The flywheel line condition can be conveniently observed through the flywheel line observation port 6. The position of the flywheel line observation port 6 does not interfere with other components and is convenient for observation.

[0033] The flywheel housing structure disclosed in this embodiment reduces the weight of the flywheel housing, making the engine lighter, adjusting the position of the flywheel speed collection sensor to make its installation and maintenance more convenient, optimizing the processing procedures to better ensure the processing accuracy of the flywheel housing, and adjusting the installation position of the external accessory "air filter" to make its installation more convenient and the structure more compact.
